Coating standard: wind power protective coating standard and certification

Core tip: at present, there is no national standard for wind power anti-corrosion technology, mainly referring to the requirements for anti-corrosion in relevant national standards of wind turbine Foreign countries have unified standards for wind power protection and regulations on all aspects of anti-corrosion technology China has established leading group, expert consultation group and Standardization Technical Committee for wind power standard construction in energy industry, and will soon set up wind power standard system, including six categories of standards, including wind power plant planning and design, wind power plant construction and installation, wind power plant operation and maintenance management, wind power grid connection management technology, wind power mechanical equipment, wind power electrical equipment, etc Among them, coating protection for wind power equipment Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: there is no national standard for wind power anti-corrosion technology, mainly referring to the requirements for anti-corrosion in relevant national standards of wind turbine Foreign countries have unified standards for wind power protection and regulations on all aspects of anti-corrosion technology China has established leading group, expert consultation group and Standardization Technical Committee for wind power standard construction in energy industry, and will soon set up wind power standard system, including six categories of standards, including wind power plant planning and design, wind power plant construction and installation, wind power plant operation and maintenance management, wind power grid connection management technology, wind power mechanical equipment, wind power electrical equipment, etc Among them, the wind power equipment coating protection standards should be made relevant provisions The rules for offshore wind turbines formulated by China Classification Society has organized and passed the review meeting The specification for offshore wind turbines puts forward technical requirements for corrosion protection of steel structure, mechanical parts, electrical parts, internal and external surfaces of concrete infrastructure and external surfaces of wind turbine blades The national standards for wind turbines mainly include the following, including the coating part: Safety requirements for wind turbines (gb18451.1-2001) / national standards of the people's Republic of China; code for acceptance of wind turbines (GB \ t20319-2006) / national standards of the people's Republic of China; Wind turbine tower (GB \ t19072-2003) / national standard of the people's Republic of China; JB / t10194-2000 wind turbine blade / machinery industry standard The determination of anti-corrosion coating for steel structure of wind farm is mainly based on three standards: 1) iso12944 color paint and varnish - corrosion protection of protective coating system for steel structure (1998): iso12944 is an important standard of anti-corrosion coating system for steel structure in various corrosion environments, especially in atmospheric corrosion environment 2) norsokm501 surface treatment and protective coating (Rev 4, 2004): norsokm501 is an important standard for anticorrosive coating and coating of offshore oil platforms in northern Europe, so it is also an important reference standard for steel structure protection of offshore wind farms 3) iso20340 paints and varnishes - Performance requirements for offshore engineering and related structure protective coating system (2003): iso20340 is the minimum performance requirements for offshore steel structure anti-corrosion coating, which is an important complementary reference standard of iso12944 for offshore steel structure anti-corrosion coating Therefore, iso20340 is also an important reference standard for steel structure coating system of offshore wind farm At present, the most authoritative certification of wind power coating is GL certification of GL It has a complete set of wind turbine standards, including wind power coating standards Several foreign manufacturers of galenic coatings, such as Mankiewicz, bergolin, Maga and PPG, have passed the GL certification The main test items and basis of GL certification include: viscosity (iso2284), density (iso2881), nonvolatile content (iso3251), hardness (iso1519), bending (iso9352), wear resistance (iso7784), aging resistance (ISO11341), adhesion test (iso4624) The adhesion test was carried out under two conditions: A FRP sample, 24h; B steel plate, 480h salt spray, 720h water condensation Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
