Improvement method of standard inspection sieve

Abstract

The invention provides an improvement method of a standard inspection sieve. The improvement method comprises the following concrete steps: 1, a commercially available inspection sieve is selected, paper or other coverings in the proper size are sheared and are fixed or pasted on the upper surface and the lower surface of a sieve net; 2, a layer of paint can be coated on the side frame surface of the inspection sieve by a brush coating method or a spraying coating method; 3, the paint is also coated on the other side of the inspection sieve according to the method in the step 2; and 4, the inspection sieve obtained in the step 3 is placed in a place with good ventilation, the drying is carried out for 30 minutes, then, the inspection sieve is placed in a 105-DEG-C oven, the constant-temperature baking is carried out for 2 hours, and the manufacture is completed. The improvement method has the advantages that the side frame surface of the merchant standard inspection sieve is subjected to paint coating improvement, when a wet sieve method is used for inspection, the water corrosion on the side frame material of the inspection sieve can be effectively avoided, the service life of the sieve is greatly prolonged, resources are saved, in addition, the side frame rusting condition is also eliminated, the rust slag cannot be generated, and sieve residues are also favorably judged.

Description

technical field [0001] The invention relates to solid separation technology, in particular to an improved method of a standard inspection sieve. Background technique [0002] In the paint and pigment industry, there are specific performance requirements for the particle size of the pigment to ensure that the paint film is smooth and smooth without particles. According to the industry standard HG / T 3852-2006, many companies use the wet sieving method to test the particle size of pigments. [0003] The industry standard HG / T 3852-2006 stipulates the inner diameter and outer diameter of the sieve, and each enterprise independently selects the aperture of the sieve according to the use requirements. However, there is no clear regulation on the material of the sieve. Many standard inspection sieves currently on the market are made of stainless steel, but the frame of the sieve is mostly made of galvanized sheet or tin-plated sheet. When inspecting according to the wet sieving m...

Problems solved by technology

[0004] In order to overcome the defects of the existing commercially available standard test sieves, this application provides a method for improving the standard test sieves. The surface of the frame of the commercially available standard test sieves is improved by painting. When using the wet sieve method for testing, it can effectively avoid The corrosion of water on the frame material of the inspection sieve greatly prolongs the service life of the sieve and saves resources. In addition, it also eliminates the rusting of the frame and no more rust residues, which is also conducive to the judgment of sieve residues
