Paint knowledge | main defects of emulsion paint coating: cracking

Core tips: causes: · low construction temperature of emulsion paint, poor water resistance of putty layer, easy cracking, unreasonable supporting system, poor coating, excessive dilution or too thick coating, poor substrate treatment prevention methods: · thoroughly treat the substrate, do not use poor putty; · select excellent coating and reasonable system, and construct according to the specified requirements Treatment method: · remove the cracks, smooth the edges, and apply the primer and recoat in strict accordance with the regulations Several ways of roller coating Recommended introduction: roller coating includes rubber roller coating, insert plate roller coating and ceramic rubber roller coating The following is a detailed introduction of these three ways of coating The function of roller rubber coating is to increase the friction derivative between the conveyor belt and the cylinder surface during transmission, so as to reduce the friction coefficient of the conveyor belt on the cylinder surface, reduce the mutual wear of the sliding machine of the conveyor belt on the cylinder surface, improve the traction force during operation, and extend the service life of the conveyor belt and the electric roller One, three, six, 8385-7180 (V) rubber rollers are covered with diamond rollers and flat rollers, generally pure rubber plates The rubber coating of the inserted plate roller is divided into tile shell type roller and Home of coatings: causes: · low construction temperature of emulsion paint, poor water resistance of putty layer, easy cracking, unreasonable supporting system, poor coating, excessive dilution or too thick coating, poor substrate treatment prevention methods: · thoroughly treat the substrate, do not use poor putty; · select high-quality coating and reasonable system, and construct according to the specified requirements Treatment method: · clear the cracks, smooth the edges, and lay the foundation strictly in accordance with the regulations The home of repainting is focused on the coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fireproof coating,
