Coating process: production process of heavy-duty anticorrosive coating

Core tips: China performance coatings network news: Production process of heavy anticorrosive coating With the development of modern industry, the emergence of a number of new industrial fields and the construction of many modern projects, the ability to withstand the environment and the service life of anticorrosive coatings are put forward higher requirements The common anticorrosive coating can not meet these needs The concept of "heavy duty coating" put forward by people generally refers to the coating used in harsh corrosive environment, including primer and top coat Simply put: heavy duty anticorrosive coating is longer service life, more adaptable 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 With the development of modern industry, the emergence of a number of new industrial fields and the construction of many modern projects, the ability to withstand the environment and the service life of anticorrosive coatings are put forward higher requirements The common anticorrosive coating can not meet these needs The concept of "heavy duty coating" put forward by people generally refers to the coating used in harsh corrosive environment, including primer and top coat Simply put: heavy-duty anticorrosive coating is a kind of coating with longer service life and can adapt to more severe use environment, which is called heavy-duty anticorrosive coating In chemical atmosphere and marine environment, heavy-duty anticorrosive coating can be used for more than 10 years or 15 years, in acid, alkali, salt and solvent medium, and under certain temperature corrosion conditions, it can be used for more than 5 years The application of heavy-duty anti-corrosion coating involves various fields of modernization Large industrial and mining enterprises: chemical industry, petrochemical industry, iron and steel, pipes, tanks and equipment for smelting in large mines, etc.; important energy sources Industry: natural gas, oil pipes, oil tanks, power transmission and transformation, nuclear power equipment, coal mines, etc.; modern transportation: bridges, ships, containers, trains and automobiles, etc.; emerging marine engineering Offshore facilities, coastal and Gulf structures, offshore oil drilling platforms, etc The coating with epoxy resin as the main film-forming material is called epoxy coating Every year, more than 40% of the world's epoxy resins are used to make epoxy coatings, most of which are used in the field of anti-corrosion Epoxy anticorrosive coating is one of the most widely used and important heavy anticorrosive coatings in the world The epoxy coating in the production process is composed of a and B components, with solvent added Component A: (paint part) select ingredients according to the ingredient scheme → crush, dry and dehydrate → weigh and accurately measure into the kettle, Seal tightly, send electricity for heating, reaction, dehydration, reflux, stirring for 30-40 minutes → cut off the power supply and exit the kettle in the high-speed disperser, add dry and metered pigments and fillers, stir vigorously for 30-40 minutes → grind to make its fineness reach the standard → put it in the disperser, mix, measure the viscosity (coating-4 viscometer) to reach the standard → separate and weigh the paint → measure the solid content, adhesion and flexibility Physical and mechanical properties such as property, etc shall be packed and warehoused after all indexes are qualified Component B: (curing agent part) proportioning according to different epoxy coating schemes → in the disperser → power transmission and even mixing → discharging, screening, separation, weighing and warehousing Diluent part: prepare diluent according to diluent proportioning scheme of various epoxy coatings → filter, sub pack, weigh and store 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,
