Common knowledge of coating: what are the contents and characteristics of functional putty

Core tip: functional putty for exterior wall refers to the putty that can meet some special needs in finishing works It is mainly used for the treatment of special base, not the traditional leveling function of base For example, the flexible water-resistant putty with certain deformation ability suitable for base treatment of various external wall external insulation systems; the elastic putty with good covering effect for base cracking; the roughing putty that can reflect special decoration effect; the ceramic tile renovation putty that directly renovates the old ceramic tile surface and then performs decoration; the special putty for metallic paint matching with the construction and application of various metallic paints on the external wall Zi et al 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: functional external wall putty refers to the putty that can meet some special needs in the finishing project, mainly used for the treatment of special base, not the traditional leveling function of the base For example, the flexible water-resistant putty with certain deformation ability suitable for base treatment of various external wall external insulation systems; the elastic putty with good covering effect for base cracking; the roughing putty with special decoration effect; the old ceramic tiles Directly renovate the surface and then decorate the tile with renovated putty; apply the special putty of metal paint matching with the construction of various metal paint on the exterior wall, etc (1) Elastic putty, also known as anti cracking elastic putty, is mainly used to solve the common quality problems of external wall cracking Elastic putty is generally composed of a larger proportion of polymer elastic emulsion as binder, and cement or other fillers and auxiliaries It can be paste like single component or two-component product The use method is basically the same as that of ordinary putty for exterior wall The putty has good fracture elongation and tensile strength, so it has certain elasticity and can resist wall cracking (except structural cracks) Although the price is on the high side, it is often used in high-grade exterior wall decoration, old building reconstruction and renovation projects (2) Due to the inevitable defects and accidents of ceramic tile and mosaic facing and the rapid development of architectural coatings in recent years, local governments have issued some policies to restrict the use of ceramic tile and mosaic and promote the development of architectural coatings Many projects require that the old ceramic tile finish be changed to paint finish, but they do not want to destroy the original tiles In view of this demand, the ceramic tile renovation putty came into being, which solved the problem that the coating can not be directly used for the old ceramic tile surface renovation It can save the tedious process of removing tiles and re plastering, which is convenient, economical and does not disturb the residents It is a kind of product with rapid development and more application in recent years This kind of putty is mainly composed of special polymer latex and cement, and is made up of special glue and special powder This kind of putty has very good water resistance and adhesion It can be applied directly on the glaze of old ceramic tiles (or mosaics), instead of the traditional treatment method of removing ceramic tiles (or mosaics) and reapplying cement mortar (3) Metal paint, resin curtain wall construction supporting putty Different manufacturers call it different, but the main function of putty is to solve two problems: first, to solve the cracking problem after the construction of metal paint and resin curtain wall, so it is usually made to meet the requirements of crack resistant putty (mortar) by using glass fiber mesh; second, to solve the flatness problem, because the flatness of metal paint and resin curtain wall construction requirements is high, and the operability of putty is good, It is easy to level and polish The putty is often a series of supporting products, such as bottom putty, crack resistant putty, smooth putty, oily putty, etc 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,
