Coating general knowledge: coating adhesion quality management of floor coating project

Core tip: the adhesion of epoxy floor coating is an important sign of coating engineering quality, but there is no correct article in construction specifications and quality inspection and evaluation standards to test the adhesion of epoxy floor coating The adhesion of epoxy floor coating is the basis of the service life of the coating project The coating thickness is related to the service life, but there is no certain proportion relationship Under the condition that other influencing factors are consistent with the objective law, the coating thickness is beneficial to prolong the life In the code of coating design, Hg / j20587-96 code for coating design of chemical building, 5.2 for the selection of floor paint primer 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 Home of coatings: the adhesion of epoxy floor coating is an important sign of coating engineering quality, while there is no correct article in the construction specifications and quality inspection and evaluation standards to test the adhesion of epoxy floor coating The adhesion of epoxy floor coating is the basis of the service life of the coating project The coating thickness is related to the service life, but there is no certain proportion relationship Under the condition that other influencing factors are consistent with the objective law, the coating thickness is beneficial to prolong the life In the specification of coating design, article 5.2.8 in the code for coating design of chemical buildings (Hg / j20587-96) on the selection of floor paint primer: nth = "12" isrocdate = "false" islunadate = "false" day = "30" > 5.2.8: "the adhesion of primer and cement base shall not be lower than grade 2, and the adhesion of primer of anti-corrosion floor paint shall be grade 0." In this paper, we will not comment on whether the standard of adhesion is high or low Finally, we found a professional standard and talked about the testing requirements of coating adhesion The quality problems of floor paint coating project, such as sagging and missing painting, are exposed immediately after the completion of floor paint coating Some problems are months or one or two years later, such as blistering and falling off, which will not be exposed in the project quality acceptance stage This is exactly the reflection of the hidden danger of poor adhesion and the essence of floor paint coating project quality The adhesion of the floor paint coating is determined by the variety and performance of the coating, surface treatment quality (rust grade, derusting grade and roughness of the base material), construction environment conditions (temperature, relative humidity), coating interval time of the supporting floor paint between layers and maintenance of the floor paint coating, etc., which becomes the quality control point of the coating project If each link is grasped, the adhesion of the floor paint coating can be achieved It is ensured that the service life of the floor paint coating project can reach the expected target of the design 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,
