QB/T 1950-1994 "Determination of Salt Bath Resistance of Furniture Surface Film" is a light industry standard, which stipulates the determination method of the salt bath resistance of furniture surface film. The content includes the test principle (evaluating the resistance by the corrosion effect of the salt bath solution on the film), equipment (constant temperature water bath device, salt solution preparation equipment, etc.), sample preparation (simulating the furniture film surface), test steps (salt solution concentration control, soaking time setting, film Appearance and performance observation) and result judgment. This standard is applicable to the testing of salt corrosion resistance performance of various furniture surface films, providing a technical basis for evaluating the stability of films in humid salt environments, and helping to improve furniture coating mass and service life.
