Abstract

The invention discloses a PRTV coating testing sample preparation die and a sample preparation method thereof. The PRTV coating testing sample preparation die comprises a die body, a die outer edge, an outer disc and multiple sample preparation grooves positioned in the undersurface of the outer disc, uniformly distributed along the center of the outer disc and close to each other are arranged onthe die body, the die outer edge is higher than the surface of the outer disc, at least three sample preparation grooves are formed, cross section of each sample preparation groove is round, and the cross sections of the sample preparation grooves are identical. By the PRTV coating testing sample preparation die, efficient and standard sample preparation of a PRTV coating can be realized; the dieis uniform in coating sample preparation thickness, low in defective rate and good in practical effect, and samples prepared by the die are free of adhesion with the die.

Description

technical field [0001] The invention relates to the field of paint sample preparation, in particular to a PRTV paint detection sample preparation mold and a sample preparation method thereof. Background technique [0002] As an important part of the anti-pollution flashover performance of electrical external insulation equipment, PRTV anti-pollution flashover coating plays an important role in ensuring the safe operation of the power system. PRTV anti-pollution flashover coating has excellent electrical and mechanical properties, strong hydrophobicity and hydrophobic migration, good adhesion, long service life, flammability index not lower than FV-1 level, non-conductive residue after combustion, spraying PRTV anti-fouling After the pollution flashover coating, the power external insulation equipment can be cleaned and maintained without cleaning, saving a lot of manpower and material resources. It is widely used in AC and DC power transmission and transformation equipment. ...
