________________________________________________________________________ Foreword
This “Specification for the Application of Thermal Spray Coatings (Metallizing) of Aluminum, Zinc, Their Alloys, and Composites for the Corrosion Protection of Steel” is issued to meet a critical industry and government need. Thermal spray coatings (TSCs) are used extensively for the corrosion protection of steel and iron in (1) a wide range of environments. The corrosion tests carried out by the American Welding Society (2) and the marine-atmosphere performance reports of ASTM and the LaQue Center for Corrosion (3) Technology confirm the effectiveness of flame-sprayed aluminum and zinc coatings over long periods of time in a wide range of hostile environments. The British Standards Institution “Code of (4) Practice for the Corrosion Protection of Steel” specifies that only TSCs give protection for more than 20 years to first maintenance for the 19 industrial and marine environments considered and that only sealed, sprayed aluminum or zinc gives such protection in seawater immersion or splash zones. This standard may be used by owners, and design, fabrication, and maintenance engineers to detail and contract for the application of TSCs for the preservation and maintenance of steel structures. This standard may also be used by TSC inspectors and TSC applicators to develop and maintain application procedures, equipment inventory, and an operator-training program. This standard presents the basic need-to-know information for the application of quality TSCs. Appendixes present amplifying information. The Table of Contents gives an overview of this standard and may be used to find specific information. This standard was prepared by the AWS C2B Subcommittee on Thermal Spray Coatings for Corrosion Protection, SSPC C.1.2.B Committee on Thermal Spraying, and NACE Task Group (TG) 146 on Thermal Spray Coatings. TG 146 is administered by Specific Technology Group (STG) 02 on Protective Coatings and Linings—Atmospheric, and is sponsored by STG 39 on Process Industry—Materials Applications.

NACE No. 12/AWS C2.23M/SSPC-CS 23.00 ________________________________________________________________________ Section 1: General
1.1 General This standard is a procedure for the application of metallic thermal spray coating (TSC) of aluminum, zinc, and their alloys and composites for the corrosion protection of steel. Required equipment, application procedures, and in-process quality control (QC) checkpoints are specified. This standard may be used as a procurement document. Appendix A presents a fill-in-the-blanks model procurement specification. The flow diagram in Figure 1 provides an overview of the thermal spray coating process presented in this standard.
Sealer or Sealer and Topcoat Application
Figure 1: Thermal Spray Coating Process
Not included in this standard are requirements for design and fabrication, thermal spray equipment qualification, coating selection, and operator and inspector certification. For successful thermal spray application, the steel structure and components should be designed and fabricated according (5) Additional consideration to NACE Standard RP0178. should be given to weldments whose oxyfuel cut edges may affect hardness which may preclude adequate profile depth. 1.2 Safety The basic precautions for thermal spraying are essentially the same as for welding and cutting. Information on safety can be found in the Safety Chapter in AWS Thermal Spraying: Practice, Theory, and Application; ANSI Z49.1, Safety (6) in Welding, Cutting; and Allied Processes; and NFPA 58, Standard for the Storage and Handling of Liquefied Petroleum Gases. Safety precautions can also be found in the manufacturer’s equipment technical instructions and manuals and the feedstock Material Safety Data Sheet. This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

--`,,,,,-`-`,,`,,`,`,,`---
Potential thermal spraying hazards include exposure to vapors, dust, fumes, gases, noise (from the spray gun), and arc ultraviolet (UV) radiation. Additionally, improperly used thermal spray equipment can create potential fire and explosion hazards from the fuel and carrier gases and a potential electrical shock hazard from the electrical and electronic equipment and charged wire spools. To minimize hazards, proper safety precautions shall be followed. Operators shall comply with the procedures in the safety references, the manufacturer’s technical manuals, and the material safety data sheets. Thermal spraying can be a completely safe process when performed by an operator who follows the recommended precautionary measures, has a proper understanding of thermal spraying practices, and has knowledge, skill, and exercises care in using thermal spray equipment. 1.3 Units of Measure This specification makes use of both the International System (SI) and U.S. Customary units. The measurements are not exact equivalents; therefore each system must be used independently of the other without combining in any way.

3.3 Bond Test: A test to determine the tensile strength of a thermal spray coating. 3.4 Companion Coupon: A small rectangular metal sample surface prepared and coated concurrently with the workpiece, used for inspection. 3.5 Contract Pre-Award Validation: The purchaser’s contract pre-award evaluation of the thermal spray coating applicator includes (a) written procedures for and (b) demonstration of surface-preparation and thermal spray materials, equipment capabilities, and application process proposed for the contract work. 3.6 Cut Test: The TSC cut test shall consist of a single cut 40 mm (1.5 in.) long through the TSC to the substrate without severely cutting into the substrate. All cuts shall be made with sharp-edge tools. The chisel cut shall be made at a shallow angle. The cutting tool shall be specified in the contract. 3.7 Holding Period: Holding period is the time between the completion of the final anchor-tooth blasting, or final brush blasting, and the completion of the thermal spraying. The holding period, by definition, ends with the onset of rust bloom. 3.8 Job Control Record (JCR): The JCR is a record form that enumerates the essential job information and the inprocess QC checkpoints required by this standard. The JCR includes information on safety precautions, and the equipment, parameters, and procedures for surface preparation, thermal spraying, and sealing or sealing and topcoating. Appendix B is a model JCR. 3.9 Job Reference Standard (JRS): The JRS is a job site pass/fail reference standard representative of the whole job or major sections of the job. See Paragraph 13.2 and Figure 2.

3.10 Overspray: The portion of the thermal spray deposit that is not deposited on the desired area of the workpiece. 3.11 Rust Bloom: Discoloration indicating the beginning of rusting. For the purpose of this standard, rust bloom is rusting that occurs after specified surface preparation. 3.12 Sealer: The sealer is a thin paint coat about 38 μm (1.5 mils) thick that is absorbed into the pores of the TSC. Aluminum and zinc TSCs have porosities ranging up to 15%. Interconnected porosities may extend from the surface to the substrate. Sealing extends the service life. Sealing is accomplished (a) naturally by the oxidation of the sprayed aluminum or zinc filling the pores with a tightly adherent oxide layer or (b) by applying thin paint sealer coatings that penetrate and are absorbed into the pores of the TSC. 3.13 Soluble-Salt Contaminants: These water-soluble salts are inorganic compounds (such as chlorides and sulfates) that contaminate a product. If soluble salts are present on a prepared steel surface, they may cause rust bloom and premature coating failure. 3.14 Topcoat: The topcoat is a paint coat over the seal coat. Note: Paint topcoats should never be applied over an unsealed TSC.

For critical surfaces and marine and underwater service, clean to a white metal finish (NACE No. 1/SSPC-SP 5) with ≥65 μm (2.5 mils) angular profile. The owner should specify the minimum required blast quality and its validation according to Section 5, Job Reference Standard. The angularity of the blast profile can be determined by a metallographic analysis of a companion coupon according to ASTM E 3 using a specimen cut from a successful bend coupon prepared and thermal sprayed per the contract specifications and tested according to Paragraph 6.5. (B) Verification that the manufacturers or suppliers provide a certificate or affidavit that (1) the blasting media conforms to SSPC-AB 1 for mineral and slag abrasive, SSPC-AB 2 for recycled ferrous metallic abrasives, or SSPC-AB 3 for newly manufactured or remanufactured steel abrasive; (2) the TSC-feedstock chemical composition, obtained from a representative sample of each heat during the pouring or subsequent processing, conforms to ANSI/AWS C2.25; and (3) the sealer and topcoat paints are formulated for the contract-specified thermal spray coating. The Material Safety Data Sheets (MSDS) provide supporting physical and chemical information. (C) Measure the TSC thickness according to SSPC-PA 2. Calibrate the instrument using a calibration wedge near the contract-specified thickness placed over a representative sample of the contract-specified abrasive blasted steel, a prepared bend coupon, or both. (D) Specify the ASTM D 4541 self-adjusting portable tensile instrument to be used and its minimum acceptable value for the Job Reference Standard and the job work surfaces. (E) As an alternative to the portable tensile-bond test, which may be considered potentially destructive on a finished part, a companion coupon may be bend tested, or a companion tensile test specimen may be tested in accordance with ASTM C 633 to validate the coating adhesion strength. The bend test is a macro system test for proper surface preparation, equipment set-up, and spraying parameters. (F) Metallographic analysis of a companion coupon may be specified to establish the suitability of the surface preparation, TSC application, and/or porosity of the TSC. (G) TSC cut test should be made by a tool cutting through the TSC to the steel surface. The TSC is defective if any part of the coating lifts off the surface.

Feedstock Zn Al 85/15 Zn/Al 90/10 Al2O3 MMC 6.4.1.2 One portable tensile-bond measurement 2 2 shall be made every 50 m (500 ft ). If the tensile bond is less than the contract specification, the degraded TSC shall be removed and reapplied. 6.4.1.3 For nondestructive measurement: Tensile force shall be measured to the contract-specified tensile. The tensile force shall then be reduced and the tensile fixture removed without damaging the TSC. 6.4.2 Note: The tensile-bond measurement of the portable test instrument may be calibrated according to the ASTM C 633 test method as described in Appendix C. MPa (psi) 3.45 (500) 6.89 (1,000) 6.89 (1,000) 6.5 Bend Test 6.5.1 The bend test (180° bend on a mandrel) is used as a qualitative test for proper surface preparation, equipment setup, and spray parameters. The bend test puts the TSC in tension. The mandrel diameter for the threshold of cracking depends on substrate thickness and coating thickness. 6.5.2 Table 4 summarizes a very limited bend-test cracking threshold for arc-sprayed zinc TSC thickness on steel coupons 1.3 mm (0.05 in.) thick versus mandrel diameter.

7.3 Post-Blasting Substrate Condition and Thermal Spraying Period 7.3.1 Steel Surface Temperature 7.3.1.1 The steel surface temperature shall be at least 3°C (5°F) above the dewpoint of the ambient air temperature. 7.3.2 Holding Period 7.3.2.1 Time between the completion of the final anchor-tooth blasting (or final brush blasting) and the completion of the thermal spraying should be no greater than six hours for steel substrates with the following exceptions: (1) In high-humidity and damp environments, shorter holding periods shall be used. If rust bloom or a degraded coating appears at any time while spraying, spraying shall be stopped. (See Paragraph 8.2.4.) (2) In low-humidity environments or in controlled environments with enclosed structures using industrial dehumidification equipment, it may be possible to retard the oxidation of the steel and hold the surface finish for more than six hours. The TSC applicator, with the concurrence of the purchaser, can establish a holding period greater than six hours by determining the acceptable temperature-humidity envelope for the work enclosure by spraying and analyzing bend coupons, tensilebond specimens, or both. The following method shall be used for bend-test coupons: (a) establish, measure, and record the low-humidity environment; (b) prepare four bend-test coupons according to contract specifications; (c) place bend-test coupons in the low-humidity environment; (d) after target holding period duration, apply the contractspecified thermal spray coating; (e) perform the bend test according to Paragraph 6.5; (f) the lowhumidity environment and holding period are satisfactory if the four bend coupons meet the requirement of Paragraph 6.6.3 (2). Alternately, tensilebond specimens can be similarly tested. (3) For small and movable parts, if more than 15 minutes is expected to elapse between the completion of surface preparation and the start of thermal spraying, or if the part is moved to another location, the prepared surface should be protected from moisture, contamination, and finger/hand marks. Wrapping with clean ink-free paper is normally adequate. 7.4 TSC Flash Coat 7.4.1 Application Time 7.4.1.1 A 25- to 50-μm (1- to 2-mil) flash coat of the TSC may be applied within six hours of completing surface preparation to extend the holding period for up to four more hours beyond the complete application of the flash coat. The final TSC thickness, however, shall be applied within four hours of the completion of the application of the flash coat provided the TSC can be maintained free of contamination. 7.4.2 Validation Procedure 7.4.2.1 The use of a flash TSC to extend the holding period shall be validated with a tensile-bond measurement, bend test, or both. The use of a flash TSC shall be validated by: (1) Cleaning and abrasive blasting a representative job area for a portable tensile-bond measurement, a bend-test coupon, or both. (2) Applying a flash TSC. (3) Waiting the delay period and applying the final TSC thickness. (4) Measuring the tensile bond, performing the bend test, or both. 7.4.2.2 The flash TSC and holding period are acceptable if the tensile bond, bend tests, or both, are satisfactory.

8.2 Thermal Spraying 8.2.1 Crossing Passes 8.2.1.1 The specified coating thickness shall be applied in several crossing passes. The coating tensile-bond strength is greater if the spray passes are kept thin. Laying down an excessively thick spray pass increases the internal stresses in the TSC and decreases the ultimate tensile-bond strength of the total TSC. The suitability of the crossing-pass thickness shall be confirmed with a bend test, tensile-bond measurement, or both. 8.2.2 Manual Spraying 8.2.5 TSC Thickness 8.2.2.1 For manual spraying, right-angle crossing passes shall be used to minimize the thin areas in the coating. 8.2.3 Mechanized Spraying 8.2.3.1 For mechanized spraying (mechanized movement of the gun, workpiece, or both), overlapping and crossing passes shall be programmed to eliminate thin spots and stay within the coating thickness specification. 8.2.4 Rust Bloom 8.2.4.1 If rust bloom, blistering, or a degraded coating appears at any time during the application of the TSC or flash TSC, the following procedure applies: (1) Stop spraying. 8.2.5.1 The TSC thickness shall be that specified in Table 1 and Paragraph 6.1.3.
--`,,,,,-`-`,,`,,`,`,,`---
(2) Mark off the acceptable sprayed area. (3) Re-prepare the unsatisfactory areas to the required degree of surface cleanliness and surface profile, including any areas where the TSC was applied to unsatisfactory surfaces. (a) Blast the edges of the TSC to provide for a 5.0- to 7.5-cm (2.0- to 3.0-in.) featheredarea overlap of the new work into the existing TSC. (b) Apply TSC to the newly prepared surfaces, and overlap the existing TSC to the extent of the feathered edge so that the overlap is a consistent thickness.
8.2.6 Low-Temperature Spraying 8.2.6.1 Thermal spraying in low-temperature environments (below freezing) must: (1) Meet the substrate surface temperature and holding period specified in Paragraphs 7.3.1 and 7.3.2. No moisture condensation on the surface is permissible during thermal spraying. (2) Be qualified with a bend test, portable tensilebond test, or both. Note: TSCs are mechanically bonded to the substrate. Preheating may be required to improve the TSC tensile bond to the substrate and reduce internal stresses.
________________________________________________________________________ Section 9: Application of Sealers and Topcoats
9.1 General 9.1.1 Thermal sprayed steel should be sealed and/or topcoated under any of the following conditions: (1) The environment is very acidic or very alkaline (normal pH range for pure zinc is 6 to 12 and for pure aluminum, 4 to 11). (2) The metallic coating is subject to direct attack by specific chemicals. (3) A particular decorative finish is required. (4) Additional abrasion resistance is required. (5) Frequent saltwater spray, splash, or immersion service. (6) Frequent freshwater spray, splash, or immersion service, excluding potable water. 9.1.2 Sealers and topcoats shall meet the local restrictions on volatile organic compound (VOC) content. Sealer and topcoats shall be applied according to the paint manufacturer’s instructions for use with a TSC, or as specified by the purchaser. 9.2 Sealer 9.2.1 The seal coat, if applied, shall be thin enough to penetrate into the body of the TSC and seal the interconnected surface porosity. Typically the seal coat is applied at a spreading rate resulting in a theoretical 38μm (1.5-mil) dry-film thickness (DFT).

Porosity measurements are not used for in-process quality control in metallizing for corrosion protection of steel. However, a metallographic sample must be used to evaluate TSC porosity and confirm the TSC nonporous thickness for the contract-specified thickness. If required, the porosity metallographic sample should be taken from the bend coupon made during the purchaser’s witnessing of the preparation of the JRS. Specify use of sealer if (a) the service environment precludes effectiveness of the natural oxidation to “fill and seal” the pores or (b) a paint topcoat (cosmetic and/or functional purpose) is specified. Long delay times will preclude adequate penetration of the sealer into the pores of the TSC. The sealer must be chemically compatible with the TSC material and the topcoat. Instructions/Rationale
The bend test (180° bend on a mandrel) is used as a qualitative test for proper surface preparation, equipment setup, and spray parameters. The bend test puts the TSC in tension. The mandrel diameter for the threshold of cracking depends on substrate thickness, coating thickness, and mandrel diameter.
The TSC shall have a porosity ≤ __(a)__ % for each metallographic analysis of a bend coupon made during the Contract Pre-Award Evaluation, Demonstration, and Validation.

防腐施工方案_范文

防腐施工方案本文是关于范文的防腐施工方案，感谢您的阅读！防腐施工方案（一） 1、钢结构防腐蚀措施（1）耐候钢：耐腐蚀性能优于一般结构用钢的钢材称为耐候钢，一般含有磷、铜、镍、铬、钛等金属，使金属表面形成保护层，以提高耐腐蚀性。其低温冲击韧性也比一般的结构用钢好。标准为《焊接结构用耐候钢》（GB4172-84）。（2）热浸锌：热浸锌是将除锈后的钢构件浸入600℃左右高温融化的锌液中，使钢构件表面附着锌层，锌层厚度对5mm以下薄板不得小于65μm，对厚板不小于86μm。从而起到防腐蚀的目的。这种方法的优点是耐久年限长，生产工业化程度高，质量稳定。因而被大量用于受大气腐蚀较严重且不易维修的室外钢结构中。如大量输电塔、通讯塔等。近年来大量出现的轻钢结构体系中的压型钢板等。也较多采用热浸锌防腐蚀。热浸锌的首道工序是酸洗除锈，然后是清洗。这两道工序不彻底均会给防腐蚀留下隐患。所以必须处理彻底。对于钢结构设计者，应该避免设计出具有相贴合面的构件，以免贴合面的缝隙中酸洗不彻底或酸液洗不净。造成镀锌表面流黄水的现象。热浸锌是在高温下进行的。对于管形构件应该让其两端开敞。若两端封闭会造成管内空气膨胀而使封头板爆裂，从而造成安全事故。若一端封闭则锌液流通不畅，易在管内积存。（3）热喷涂铝（锌）复合涂层：这是一种与热浸锌防腐蚀效果相当的长效防腐蚀方法。具体做法是先对钢构件表面作喷砂除锈，使其表面露出金属光泽并打毛。再用热喷涂设备的热源（乙炔—氧燃烧火焰、电弧、等离子弧等）将不断送出的铝（锌）丝融化，并用压缩空气吹附到钢构件表面，以形成蜂窝状的铝（锌）喷涂层（厚度约80μm~100μm）。最后用环氧树脂或氯丁橡胶漆等涂料填充毛细孔，以形成复合涂层。此法无法在管状构件的内壁施工，因而管状构件两端必须做气密性封闭，以使内壁不会腐蚀。这种工艺的优点是对构件尺寸适应性强，构件形状尺寸几乎不受限制。大到如葛洲坝的船闸也是用这种方法施工的。另一个优点则是这种工艺的热影响是局部的，受约束的，因而不会产生热变形。与热浸锌相比，这种方法的工业化程度较低，喷砂喷铝（锌）的劳动强度大。（4）涂层法：涂层法防腐蚀性一般不如长效防腐蚀方法（但目前氟碳涂料

喷砂除锈设备及施工工艺

喷砂除锈设备及施工工艺 [摘要]研究了钢桥面防腐蚀涂装前的喷砂除锈设备与工艺问题，针对钢桥面大面积防腐蚀涂装施工要求工期短、质量高和无尘生产的特点，对比了二类喷砂除锈设备，提出了采用高效无尘喷砂除锈设备的建议，并介绍了该设备的工作原理和在钢桥面施工实例中的工艺。 [关键词]钢桥面；无尘；喷砂；除锈引言近年来，我国加大了对交通建设的投资，桥梁建设技术也在突飞猛进，新修建的大跨径钢桥大多是采用正交异形钢桥面板的钢箱梁桥，如厦门海沧大桥、江阴长江大桥、南京长江二桥、武汉军山长江大桥、舟山桃天门大桥等。为了保护桥面板，提高钢桥梁的使用寿命和行车舒适性，减少振动和噪音，桥面板必须进行防腐蚀处理并铺装高性能沥青混凝土层。由于沥青混凝土铺装层存在大量孔隙，空气中的氧气和路面积水会穿过这些孔隙到达桥面板，与桥面钢铁直接接触，从而引起桥面钢铁的腐蚀。腐蚀结果是腐蚀产物体积膨胀，使桥面板与沥青混凝土铺装层相分离；再加上路面汽车重载的碾压，急刹车、车辆启动等造成桥面不均匀受力，使得桥面沥青混凝土层产生局部变形、开裂、脱落、破损等路面损坏。因此对桥面板进行有效的腐蚀保护，才能同时保证路面沥青混凝土层的经久耐用。目前，各国钢桥桥面铺装完全成功的实例不多，主要是因为桥面板和铺装层受力十分复杂，可能导致桥面铺装层破坏的因素很多。桥面铺装仍是世界性的难题。各国桥梁专家多注重对桥面铺装层的性能和破坏机理进行研究，而常常忽略了桥面防腐层前处理喷砂除锈施工质量对桥面铺装体系的影响因素。桥面防腐涂层体系现在世界上有两大类：一类是富锌漆的油漆涂装体系，另一类是电弧喷涂锌或锌铝合金的金属涂层体系。这两大体系在我国和国外的许多钢桥面上都有应用实例，文中姑且不对其进行评论。无论采用何种涂层体系，涂装前钢材表面预处理的优劣程度都会影响涂装工程质量(涂层与钢基体的结合强度)及涂层的使用寿命，从而影响整个桥面铺装层的施工质量和使用寿命。 1 钢桥面喷砂除锈设备的选择国内外目前对钢桥面喷砂除锈的设备主要有二大类：一类是气动压力式喷砂设备；另一类是机械离心式抛砂/丸设备。二类设备的比较如表1所示。

脱硫塔内壁喷铝施工方案

脱硫塔内壁喷铝施工方案一、工程概况：脱硫塔内壁喷铝防腐二、工程内容：脱硫塔内壁喷砂除锈达到Sa2.5级，喷铝层0.3mm。三、编制依据： 1、SHJ4007-86《涂装前钢材表面处理规范》 2、GB765-886《涂料涂覆技术条件》 3、GBT126-89 《工业设备及管道防腐蚀工程施工及验收规范》 5、GB2923 《涂装前钢材表面锈蚀等级和防锈等级》 6、我公司多年来同类工程的施工经验。四、施工前准备：因为施工和准备工作是防腐工程的一个重要组成部分，它直接影响到防腐质量、进度、安全，所以要高度重视。 1、人员组织：由公司选派3-5名有组织能力、施工管理经验，懂技术的人员组成领导小组，并组织身体健康，熟练掌握喷砂、喷镀的技术人员、参加本次工程施工。施工人员将在指定开工时间前3天到达施工现场，搭设临时设施，接受管理、技术人员对施工现场、技术要求、安全文明施工的交底。做好材料、施工对象的各项防护措施。 2、技术资料准备：在工程开工前应做好相应有关资料的准备工作，如：填报开工报告、编制周施工计划、材料抽检、隐蔽记录、施工记录等工作。 3、材料准备：施工前应备齐所用的材料，并检验材料的规格，性能是否符合施工操作要求。 4、机械准备：开工前，把所用的机械设备（空气压缩机、砂罐、气

罐）就位，并进行调试。 5、备齐磅称、容器、搅拌棒、漆刷、料桶等操作工具，并保持干净清洁。 6、备齐安全帽、安全带、防毒口罩、安全鞋等劳动保护安全措施和砂子、铁锹、灭火器等消防器材。五、施工程序被喷镀脱硫塔检查→喷砂除锈Sa2.5级→试喷→喷镀→检查→涂封孔剂→养生→成品。￣六、施工方法：对被喷镀脱硫塔检查：对被喷镀脱硫塔的要求：被喷镀的脱硫塔制作应符合管道制作的有关规定或设计要求，经有关部门检查合格后。经检查验收合格方可进行喷镀。 1、表面处理：在施工过程中必须认真科学、工艺性的作好每一层次每一环节的工作，首先必须做好基材表面的预处理，因为表面处理的好坏，直接影响镀层的质量和保护年限。表面处理，本公司结合并参照国内喷镀防腐技术规范，根据我公司多年防腐技术施工经验，对基材表面采用喷砂除锈，除锈标准按照中华人民共和国标准GB8923-88Sa2.5级标准，本标准具体质量要求是：彻底的喷砂除锈、氧化皮、油脂、锈及污物和油漆等附着物，该表面应显示均匀的金属色泽，最后表面用清洁干燥的压缩空气或干净的刷子清理，同时也可参照中华人民共和国国家GB8923-88除锈等级图片对比。

热喷铝施工技术

储罐内壁热喷铝工艺及问题分析沈芝银吴建中（南化集团建设公司，南京 210044）摘要详细论述了线材火焰喷涂法进行储罐内壁喷铝的工艺，以及在施工中如何控制施工的质量，避免缺陷的发生。关键词喷砂热喷铝喷涂角度喷涂距离雾化 1 概述热喷铝是制备涂层的一种工艺方法，已成为金属表面防护的新技术之一。热喷铝技术现在已广泛应用于产品制造和设备维修，以降低产品成本，提高产品质量和延长使用寿命。在我公司承建的张家港扬子港务有限公司06罐区工程中，有3台3000M3乙二醇碳钢罐，罐内壁需喷铝，喷铝层厚度≥0.15mm。由于乙二醇原料为无色透明液体，即使储罐内表面有一点微锈，乙二醇原料都会受到污染，严重一些就会造成整罐的原料报废，给企业带来很大的经济损失和名誉损失。因此罐内表面喷铝质量至关重要，必须对喷铝工作的每一步进行严格管理和控制，保证最终的施工质量满足要求。 2 热喷铝工艺流程 3 热喷铝前表面处理： 3.1 喷砂除锈（1）储罐内表面喷铝前，必须采用铜矿砂对金属表面进行喷砂除锈，除锈结果应达到国家规范Sa3级的要求：钢材表面无可见的油脂、污垢、氧化皮和油漆涂层等附着物，该表面应显示均匀的金属光泽。表面粗糙度达到75μm以上。

（2）压缩空气必须经过性能良好的油水分离器、缓冲罐以后才能进入喷枪，压力不低于0.5MPa。（3）为了保证金属表面的粗糙度和洁净度，铜矿砂必须清洁干燥且粒度为3~5mm。 3.2 除尘处理喷砂除锈后应采用吸尘器对金属面进行除尘处理。经喷砂除锈合格的金属表面，不得用手触摸，并尽快进行喷涂，晴天时间间隔不得超过12h，雨天或潮湿的天气不得超过2h。否则应重新进行表面处理。如喷砂达不到预定要求，容易形成以下缺陷：喷砂层与金属层结合力差，容易脱落；喷铝层起皮、起壳。 4 热喷铝施工的方法和技巧 4.1 热喷铝方法选择、目前热喷铝应用较多的是线材火焰喷涂和电弧喷涂两种方法，该工程储罐喷铝的现场条件较差，所以采用线材火焰喷涂。线材火焰喷涂是研制早、应用早、技术成熟的热喷涂方法，其特点是轻便、灵活、机动性好，因此在该项目中应用尤为合适。该方法采用氧-乙炔焰作为热源，喷涂材料为铝线材。 4.2 设备、材料选用及要求线材火焰喷涂设备是由氧气及乙炔供给系统、压缩空气系统、气喷枪及丝盘等组成，见下图：

喷铝主要施工方法一、表面处理表面处理，本公司结合并参照国际与国内喷镀防腐技术规范，根据我公司多年防腐技术施工经验，对基材表面采用喷砂除锈，除锈标准按照中华人民共和国标准GB8923-88Sa3级标准，本标准具体质量要求是：非常彻底的喷砂除锈、氧化皮、油脂、锈及污物和油漆等附着物，该表面应显示均匀的金属色泽，最后表面用清洁干燥的压缩空气或干净的刷子清理。在施工过程中，我公司采用以下设备和措施 1）根据不同的工程规范范围，喷砂设备有6m3/8Kg和9m3/8Kg 空气压缩机、储气罐、油水分离器、空气滤清器、喷砂罐、胶带、喷砂枪、耐磨瓷嘴，一切机具齐备。 2）磨料选用硬度高，有棱角的0.5-1mm石英砂。砂粒干燥，含水量小于1%（含水量＜1%），清洁无杂质，喷嘴选用扩张Ｌ型瓷嘴。空气经扩张－压缩－扩张等阶段，流出砂嘴的空气流量能达到超音速状态，使喷射的磨料大大增加，使基体表面更加活化和电化，而导致镀层结合强度的增加。 3）工艺流程：压缩空气进入储气罐，经油水分离器、空气滤清器，使其清洁干燥，不含油质，然后进入砂罐，经胶带将砂粒压至喷砂枪，喷射金属基体。 4）操作工艺：操作前首先检查砂罐压力表、胶带、喷砂枪、喷嘴等机具正常时，将喷砂底气阀打开，穿好喷砂衣，系好安全带，做

好喷射前的一切准备，当砂罐压力达到8Kg/cm２时，方可将送气门打开，喷射金属基体。 5）影响喷镀层的主要原因由实践经验和理论研究证明，不但金属基体所在的环境腐蚀介质是影响喷镀层的原因，更主要的是影响喷镀层的保护年限和保护效率，是表面处理的好坏，而影响表面处理好坏的根本原因是：压缩空气压力、喷射角度、喷射后停放时间、喷射距离。 5.1压缩空气压力应在6-7Kg/cm2，常用7Kg/cm2。因在不同的压力下，表面的电极电位值不同，所以，镀层的结合强度就不同，随着空气压力的增加，表面平均粗糙度增加，其表面晶畸变更为剧烈，基体表面更加活化。因此镀层在基体上的投描效应更为显著。镀层金属与基体之间的健结合力将会上升，当压缩空气增加到7Kg/cm2，其镀层结合力达到最高点，若压力7Kg/cm2时，镀层结合强度处于饱和状态。 5.2喷射时间：喷射时间的长短，是对基体表面电极电位粗糙度和涂层的结合强度有直接影响。由实践经验证明，在实际操作过程中，对基体略喷即可，使基体表面没有什么大的变化，保持粗糙度在40-60um之间，此时为最佳粗糙度，有操作经验可知，喷射应在20秒以内，随着喷砂时间的延长，电极电位减少，表面活化增加趋于停止。镀层强度有明显的增加，由此可知，喷射时间达到20秒时，基体表面各项指标达到饱和值，此时基体表面能和镀层很好的结合和随着镀层有高的结合强度值。

钢结构件电弧喷铝工艺

钢结构件电弧喷铝工艺 11.1概述位于沿海地区，海洋性大气对钢结构的腐蚀性强，外部环境非常恶劣，同时养护条件较差，为减少养护工作量，延长涂装体系的使用寿命，采用金属热喷涂防护体系。具体涂装方案如下：注：1.表中漆膜厚度均指干膜厚度。 2.电弧喷铝的铝丝化学成份按GB/T3190-1996标准中L2要求，Al≥99.6%。 3.结构出厂前涂面漆一道，现场施工完后先对现场焊接区域进行手工除锈，依次补充涂装，然后全桥整体作清洗后涂第二道面漆。 11.2施工方案和场地平面布置

㈠总体施工方案 ⑴工件由平板运输车运进涂装车间并支撑在1米高的支撑架上进行防腐施工（机械除锈、喷砂、电弧喷涂和第一道油漆），施工完毕工件运出涂装车间放置在工件存放周转场地，在工件存放地完成剩余油漆涂装，直至达到出厂要求。 ⑵首先在存件区对待涂装工件进行净化处理，清理焊渣，清洗油污。然后运输一节工件进涂装厂房进行防腐。先对工件外表面喷砂除锈，喷砂完毕，清理钢砂后进行电弧喷铝，喷铝完毕后移支撑架对支撑架下处理不到的部位进行喷砂除锈和电弧喷铝，然后对内表面进行机械除锈。机械除锈完毕后对铝涂层封闭一道，同时对内表面喷涂第一道油漆。一节工件完成后继续运进另一工件至涂装车间进行下一轮工件防腐施工。油漆干燥后工件运出涂装车间到存放区完成后几道油漆涂装，剩最后一道面漆待整桥施工完毕后在桥址现场整体涂装以保证大桥外观美观。 ⑶为了提高防腐涂层质量，使电弧喷铝涂层性能良好，涂层细致、致密，使用二次雾化喷枪进行电弧喷涂。 ⑷运到现场的工件经安装加工单位拼焊完毕后进行焊缝和破损处防腐涂装，不同部位均采用与原涂装方案相同的工艺进行防腐蚀施工，以保证钢结构防腐蚀涂层的完整性。焊缝防腐施工与拼装进度同步，并利用拼装单位的拼装焊接作业平台、临时设施和起吊运输工具。 ⑸整拱安装完毕，焊缝防腐处理结束后对整桥涂装最后一道面漆，面漆涂装利用现场的起吊设备。 11.3防腐蚀涂装施工工艺要求㈠外表面涂装工艺要求 ⑴表面净化
