Coating classification: aging time

Core tip: curing refers to the two-component coating according to the ratio of the coating and curing agent to add curing agent to mix evenly for curing Generally, the ripening time is about half an hour The curing time of paint coating, also known as induction period, is mainly used in the construction of two-component epoxy resin coating Pure epoxy coating mostly uses polyamide as curing agent The viscosity of polyamide resin is relatively large and the miscibility of epoxy resin is not good Therefore, the epoxy coating using polyurethane curing agent needs to be well mixed with two components and placed for 15-30 minutes for curing Curing agent and epoxy resin 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 Paint Home News: curing refers to the two-component paint according to the ratio of the paint and curing agent to add curing agent to mix evenly for curing Generally, the ripening time is about half an hour The curing time of paint coating, also known as induction period, is mainly used in the construction of two-component epoxy resin coating Pure epoxy coating mostly uses polyamide as curing agent, and the viscosity of polyamide resin is larger than that of epoxy resin, so polyurethane is used The epoxy coating of curing agent needs to be cured after the two components are well stirred and placed for 15-30 minutes The mixture of aliphatic amine curing agent and epoxy resin is good, but the amine is easy to volatilize, and the amino methyl ester salt is synthesized with the moisture in the atmosphere and carbon dioxide in the air, which makes the coating white seriously, especially under the condition of low temperature and high humidity In order to overcome this disadvantage, it is necessary to mix the base material and the fixative, and then make the amine react with some epoxy resin for 15 minutes to prevent and reduce the latex paint Because of the volatility of molecular amines, modern coatings can be used without diluting Habitual diluting behavior must be avoided Diluents are mostly used for cleaning tools If diluent must be used due to environmental temperature coating method or other specific needs, pay attention to the manufacturer's instructions, and confirm that the correct diluent is used, the wrong dilution will lead to deterioration of coating quality, coating quality problems, and excessive diluent will lead to decrease of solid content of coating If the specified film thickness is not reached, the drying and curing time will be slowed down, which will cause sagging problem Generally, the coating needs to be diluted In winter, when the temperature is low, a proper amount of diluent can be added to reduce the viscosity of the coating In manual or air spraying, a diluent should be added, which is easy for construction The film thickness can be specially reduced, and a proper amount of diluent can be added The coating interval is the interval before the next coating The coating interval is related to temperature, film thickness, coating number and future exposure The adhesion of some coatings is more affected by the recoating interval than other types of coatings, such as the epoxy zinc rich surface is hard and smooth If the maximum recoating event exceeds the fixed limit, the surface of the film shall be roughened to ensure the adhesion of recoating 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,
