Paint knowledge on the correct use of adhesives

Core tips: 1 Procedure of bonding process: surface treatment for different properties of adherends and different situations It can be strictly divided into general method, chemical method and physical method In the decoration industry, it mainly deals with the glued objects simply Such as: dust, oil, rough surface, moisture and other aspects of the treatment, to ensure that the surface is clean, dry and free of oil 2 The glued surface shall be evenly glued to ensure infiltration and avoid bubbles as much as possible The bonding strength will be greatly reduced due to pores, leading to degumming Attention shall be paid to the alignment of the position at one time, and it is not allowed to move wrongly, it can be pressurized, and the air can be removed to make it closely connected 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: 1, bonding process procedures: surface treatment for different properties of the adherend and different situations, surface treatment It can be strictly divided into general method, chemical method and physical method In the decoration industry, it mainly deals with the glued objects simply Such as: dust, oil, rough surface, moisture and other aspects of the treatment, to ensure that the surface is clean, dry and free of oil 2 The glued surface shall be evenly glued to ensure infiltration and avoid bubbles as much as possible The bonding strength will be greatly reduced due to pores, leading to degumming Attention should be paid to the alignment at one time It is not allowed to move wrongly It can be pressurized to remove air and make it in close contact 3 The process of solidifying the adhesive layer through chemical and physical actions Curing is the last step to obtain bonding properties, which has a great influence on bonding strength In the curing process, temperature, pressure and time are three important parameters of the curing process The change of each parameter has a direct impact on the bonding strength (each adhesive has a specific curing temperature and time) When curing, a certain amount of pressure should be applied, which should be said to be necessary for all adhesives, because the pressure is conducive to the diffusion and penetration of the adhesive and is close to the adherend Contact helps to exhaust gas and water, avoid bubbles and pores, and make the adhesive layer uniform and the position of the adherend fixed Whether it is by chemical reaction or physical action to complete the curing of the adhesive layer, it needs a certain time In order to achieve the maximum bonding strength, it is necessary to ensure that there is enough curing time (this is usually proposed to make the adhesive reach the final adhesion for a certain time) 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,
