Method for detecting surface finish quality of dust-free cloth

Abstract

The invention relates to the dust-free cloth detecting method field, in particular to a dust-free cloth surface finish detecting method which comprises the steps of preparing at least one piece of dust-free cloth to be detected and folding the dust-free cloth, measuring the length of the folding line of the dust-free cloth, counting the number of burrs on the folding line with a selected double stereomicroscope, and calculating the dust-free cloth surface finish characteristic parameter, i.e. the density of the burrs on the folding line according to the formula: the density of the burrs on the folding line = the total number of the burrs measured each time / the total measuring distance. Accordingly, the dust-free cloth surface finish characteristic parameter, i.e. the density of the burrs on the folding line can be calculated objectively; the smaller the value of the density of the burrs on the folding line, the better the effect of the dust-free cloth surface finish. Whether the dust-free cloth surface finish of the dust-free cloth meets the requirement can be judged by comparing the dust-free cloth surface finish with the set reference density of the burrs on the folding line, sothat the problem on the detection of the dust-free cloth surface finish can be solved, and the efficiency and the reliable objectivity of the dust-free cloth can be improved. The dust-free cloth surface finish detecting method has the advantages of high precision and strong operability.

Description

technical field [0001] The invention relates to the field of detection methods for dust-free cloths, in particular to a detection method for the surface smoothness of dust-free cloths. Background technique [0002] Dust-free cloth is a kind of chemical cloth widely used in electronic optical equipment. It has high requirements for its surface finish. To achieve the "dust-free" effect, it is necessary to reduce the number of surface burrs as much as possible and eliminate potential damage Gross factor. At present, the inspection method of the surface finish of the dust-free cloth is to spread the dust-free cloth and check the burrs on the cloth surface with the naked eye based on experience. This inspection method has the shortcomings of inconsistent inspection standards and too strong subjectivity, which brings serious problems to both the supply and demand sides. A lot of disagreements came. Contents of the invention [0003] The object of the present invention is to pr...
