Paint knowledge: Causes and Countermeasures of paint particles

Core tip: what kind of infant is the particle phenomenon after painting? The particle appearance may be that dust, sand and other sundries are mixed into the paint, the bubbles are not scattered when the strip is mixed, the construction environment is not clean, and the base treatment is not qualified, etc How to solve the problem of paint particles, please see the introduction below 1 Problems: dust, flying flocs, foreign matters, etc are attached to the surface of the coating 2 The cause of the problem (1) dust, sand and other debris mixed into the paint (2) When the paint is mixed, the bubbles generated in the paint solution are not dispersed, which means that the bubbles can not be separated, especially in cold weather, making the paint film rough after drying (3) construction ring 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 Home of paint news: what is the original baby of particles after painting? The particles may be dust, sand and other debris mixed into the paint, the bubbles are not scattered when the strip is mixed, the construction environment is not clean, and the base treatment is not qualified How to solve the problem of paint particles, please see the introduction below 1 Problems: dust, flying flocs, foreign matters, etc are attached to the surface of the coating 2 Cause of the problem (1) dust, sand and other debris mixed into the coating (2) when the paint is mixed, the bubbles generated in the paint liquid will be constructed without being dispersed, especially in cold weather, which is easy to cause the bubbles to not be dispersed, making the surface of the paint film rough after drying (3) the construction environment is not clean, with dust and sand falling in the paint, or there are sundries on the brush tools such as oil brush (4) the base course treatment is unqualified, the grinding is not smooth, and the dust and sand particles are not removed (5) due to improper use of diluent and poor solubility, the paint cannot be completely dissolved, resulting in particles (6) improper use of curing agent, incompatibility with paint, resulting in particles 3 Solution (1) the prepared coating must be filtered by filter cloth before brushing to remove sundries (2) after the paint oil is prepared, it shall be left for 10-20 minutes (3) the uneven part of the base course shall be filled with putty, polished with sandpaper, and painted after the dust is removed (4) use matching diluent and curing agent (5) the surface of the coating film has been rough, which can be polished with sandpaper, and then the top coat is applied again Home of coatings focuses on coatings, paint coatings, coating technology, news and information of fire retardant coatings, coatings, coating technology, decoration knowledge and decoration renderings of fire retardant coatings,
