Determination of coating film polishing
The national standard "GB1769-(79) 88 Test Method for Polishing of Paint Film" adopts QG-1 type paint film polishing instrument, after the specified number of polishing times under a certain load, it is expressed by the gloss (%) of the coating film.
Coating film polish measurement is a method to evaluate the wear performance of coatings. It is mainly used to test the wear resistance and wear rate of the coating surface during the wear process.
Coating film polishing is usually tested using a polishing instrument, which includes a pair of rotating grinding heads and a pair of rotating polishing heads. During the test, place the grinding head on the coating surface, apply a certain force and rotation speed for abrasion, then use the polishing head to polish the worn surface, and finally measure the gloss before and after abrasion to evaluate the wear performance of the coating .
Coating film polish measurement can be used to evaluate the abrasion performance of various types of coatings, such as automotive paints, wood paints, architectural coatings, etc. By measuring the wear performance of the coating, the durability and quality of the coating can be evaluated, and basic data can be provided for formulating coating improvement and maintenance programs.
