Coating process: coating construction process of heavy-duty anticorrosive coating

Core tip: steel structure anti-corrosion coating project includes three parts: engineering design, engineering construction and engineering management Its goal is to achieve technical reliability, economic rationality and construction feasibility according to the anti-corrosion requirements of steel structure project In recent years, with the development of steel structure manufacturing industry, coating technology has been paid more and more attention Some scholars have put coating technology and welding technology together, which are called two pillars of steel structure manufacturing The coating process of steel structure has gradually stepped into standard operation For a long time, iso8501 (equivalent to gb8923), iso85 Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Coating home news: the steel structure anti-corrosion coating project includes three parts: engineering design, engineering construction and engineering management Its goal is to make efforts to achieve technical reliability, economic rationality and construction feasibility according to the anti-corrosion requirements of the steel structure project In recent years, with the development of steel structure manufacturing industry, coating technology has been paid more and more attention Some scholars have put coating technology and welding technology together, which are called two pillars of steel structure manufacturing The coating process of steel structure has gradually stepped into standard operation For a long time, iso8501 (equivalent to gb8923), iso8503 and other international standards have been guiding documents for coating process China has also successively formulated relevant specifications on coating process of steel structures, such as gb2705-198, GB50205-2001, gb50212-2002, etc The former Ministry of railways, the Ministry of water resources and electric power and so on have formulated more detailed industrial standards for steel structure coating, such as TB / t1527-1995, Yb / t9256-1996, SY / t0447-1996, sl15-1995 and so on Especially in recent years, the International Standardization Committee has issued an international standard which has guiding significance for coating process For example, the international standard iso12944-1998 on heavy-duty anticorrosive coating and coating provides rules for coating process in surface treatment, coating matching, film thickness control, determination of coating service life, etc The coating process of steel structure specifically includes the following five works: ① surface treatment before coating ② Determine the matching system of anti-corrosion coating ③ Determine the coating process flow ④ Spraying construction of heavy anticorrosive coating ⑤ Inspection and evaluation of coating quality According to the relevant specifications of iso12944-1998 international standard, it is divided into three parts: coating process, surface treatment and spraying construction of heavy-duty anticorrosive coating 2 In the current steel structure manufacturing industry, the coating process is divided into two processes according to whether there is steel pretreatment equipment or not First, large steel structure manufacturers like Jiangnan Heavy Industry (Group) Co., Ltd., Shanghai guandar Steel Structure Co., Ltd., Wuchang Shipyard, etc all of them are equipped with steel plate or section steel pretreatment lines In this equipment, the steel raw materials are shot blasted first to remove the oxide skin and rust on the surface, spray shop primer and dry to prevent rust in the process interval This kind of coating process flow is as follows: second, for some small and medium-sized steel structure manufacturers without steel plate preprocessing, their coating process flow is as follows: paint house focuses on coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fireproof coating,
