Coating technology: several points for attention in construction coating

Core tip: coating construction is a very important link in the process of coating from semi-finished products to finished products The selection of high-quality coatings in architectural decoration engineering is to meet the requirements of architectural protection and decoration, and is the basic guarantee for the completion of high-quality coating engineering However, the reality is that high-quality coatings may not be able to make high-quality projects The reason lies in: people generally pay more attention to the performance and quality of the coating, but they do not pay enough attention to the coating construction technology, and the coating engineering quality accidents caused by the grass-roots reasons and improper construction are common Therefore, it is necessary to be familiar with the performance and characteristics of the coating substrate Various coatings 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 Coating home news: coating construction is a very important link in the process of coating from semi-finished products to finished products The selection of high-quality coatings in architectural decoration engineering is to meet the requirements of architectural protection and decoration, and is the basic guarantee for the completion of high-quality coating engineering However, the reality is that high-quality coatings may not be able to make high-quality projects The reason lies in: people generally pay more attention to the performance and quality of the coating, but they do not pay enough attention to the coating construction technology, and the coating engineering quality accidents caused by the grass-roots reasons and improper construction are common Therefore, it is necessary to be familiar with the performance and characteristics of the coating substrate The construction requirements of all kinds of coatings, to achieve the organic unity of high-quality coating and strict construction, can obtain excellent coating effect 1 When the paint is applied by hand, the direction of application and the length of stroke shall be consistent with each other If the paint dries quickly, it should be dipped in short brush frequently, and the lap joint is better at the grid joint Generally, the painting layer shall not be less than two layers, and the next layer shall be painted after the former layer is dry The interval time between the two painting layers is closely related to the temperature and temperature of the construction site, usually not less than 2H 2 In the spraying construction, there are certain requirements for the viscosity of coating, air pressure, spraying distance, operation angle and speed of spray gun, etc Viscosity should be moderate, too thick for construction, too thin and easy to flow If the air pressure is too low or too high, the coating will suffer from poor texture and loss The spraying distance is between 40-60cm, the nozzle is too close to the painted wall, the coating thickness is difficult to control, and the coating consumption is large During the operation of the spray gun, the center line of the nozzle must be vertical to the wall, the spray gun should move in parallel, and the operation speed should be consistent If the spray gun runs too fast, the coating will be thinner, the color will be uneven, and if the spray gun runs too slow, the coating will adhere more, and it is easy to flow and hang The continuous operation in China shall be carried out in one go and stop at the partition joint Pay attention to the coating effect, and avoid the defects such as virtual spraying, flower face, sagging and leakage spraying 3 During roll coating construction, dip a small amount of paint on the roller, and then roll back and forth gently and steadily on the painted wall surface, straight up and down to avoid twisting and snaking, so as to ensure the consistency of coating thickness, color and texture 4 The whole process of the construction of the paintball facing must be carried out according to the requirements of the color of the sample plate designed in advance and the shape of the coating surface First brush 1-2 coats of primer on the surface of the base course, and then spray paint according to the design requirements after drying 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,
