Common knowledge of coating: analysis of the causes of the film's tarnish in putty powder construction

Core tips: 1 Causes of problems The factors that affect the gloss of putty film are the quality of putty itself and the construction method The content of the former base material (polyvinyl alcohol or redispersible polymer) and the amount of light calcium carbonate significantly affect the gloss of the film The higher the amount of base material and light calcium carbonate is, the higher the gloss of the coating is When starch ether or carboxymethylcellulose is used as the supplement of thickener or base material, the gloss of the coating will be affected, so it should be used as little as possible The latter, construction is also a very technical problem, construction is not skilled, the performance of putty is not understood Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: 1 The reasons for the problems affecting the gloss of putty coating include the quality of putty itself and the construction method The content of the former base material (polyvinyl alcohol or redispersible polymer) and the amount of light calcium carbonate significantly affect the gloss of the film The higher the amount of base material and light calcium carbonate is, the higher the gloss of the coating is When starch ether or carboxymethylcellulose is used as the supplement of thickener or base material, the gloss of the coating will be affected, so it should be used as little as possible In the latter case, the construction is also a highly technical problem Unskilled construction, lack of understanding of the performance of putty, inaccurate timing of light collection or improper operation of light collection may reduce the luster of the film 2 The prevention and control measures are to analyze the specific reasons and take corresponding measures according to the various factors that have adverse effects on the gloss of the film In case of improper use of constituent materials, it shall be solved by adjusting putty formula For example, appropriately increase the amount of base material or light calcium carbonate; try not to use or use less starch ether If the construction method is improper, it should be solved from the improvement of the construction method It is very important to master the time and operation method of light collection correctly to ensure the gloss of the film 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,
