GB 1754-1979 "Measurement of weight gain after painting of cloth cloth" is a national standard, which stipulates the measurement method of weight gain after painting of cloth. The content covers the test principle, the requirements of equipment (such as Balance), the preparation of the sample (cleaning and weighing of the cloth before and after painting), the operation of the painting process and the calculation steps of weight gain. Calculate the weight increase rate by weighing the mass difference of the cloth before and after painting. The standard is applicable to the performance testing of various types of cloth after painting. It provides a technical basis for evaluating the adhesion of paint materials and the uniformity of the process. It helps to standardize the mass inspection of the paint cloth and ensure that the coating thickness and adhesion performance meet the requirements.
