In the construction quality management of anti-static epoxy floor paint, film thickness management is a major one. The so-called film thickness management is the process of controlling the film thickness in the construction of Antistatic Epoxy Floor paint and checking and analyzing the film thickness after construction, distinguishing and quality reaction and treatment. The purpose of film thickness management is to ensure that the thickness of epoxy floor coating not only meets the thickness of planning rules to ensure protection performance, but also to prevent the waste caused by excessive thickness. 防静电环氧地坪涂装关于膜厚办理各个项均有清晰的请求，例如在涂装技术规划上，对每道应到达的厚膜和总干膜厚度都有严厉的规则，应按请求履行。
Anti-static epoxy floor coating has clear requests for film thickness management. For example, in the coating technology planning, there are strict rules for the thickness of thick film and dry film to be reached, which should be fulfilled as requested.
Film thickness management includes wet film thickness check and dry film thickness check. Wet film thickness is usually checked in time at the end of each paint brushing in the process of epoxy flooring Engineering painting. Dry film thickness can be checked in the construction process, but it is necessary to check the total dry film thickness after the completion of construction.
1. Check the wet film thickness.
Wet film thickness measurement is usually used by the coater to instruct the builder to determine the amount of Antistatic Epoxy Flooring materials required to achieve the desired dry film thickness. There are two kinds of wet film thickness gauge: wet film thickness gauge and wet film thickness comb gauge. The advantage of choosing a wet film thickness gauge is that it can inspect and correct inappropriate film thickness in the process of coating. If the builder knows the thickness of the wet film, the thickness of the dry film can be estimated by multiplying this data by the volume percentage of the solid component of the paint.
It is difficult to correct after destructive experiments in practice, so the determination of wet film thickness and the accumulation of each coating thickness and the control of coating dosage can usually be used to replace the measurement of total dry film thickness.
2. Dry film thickness check.
The main purpose of measuring dry film thickness is to ensure the thickness of coating arrival rules and prevent premature failure of coating due to inappropriate thickness, especially for floor coating. It is necessary to use dry film thickness gauge to measure dry film thickness.
Commonly used in the dry film thickness of epoxy floor, the instrument has destructive thickness gauge and caliper. Many coatings exceed the rules and specifications, which are usually not a problem, but bring excessive loss of anti-static epoxy floor coatings and the addition of painting funds. Due to the influence of coating thickness on evaporation and thorough drying of solvents and curing of the next coating, wrinkling or cracking may occur in the overly thick coating. It should be noted that. During construction, when the thickness of the membrane exceeds 10% of the maximum dry film thickness, we should try to deal with it.
