Test sieve use is divided into: general test sieves, test sieve special processing, consolidation abrasive particle inspection sieve, sieve coated abrasive particle inspection, casting test sieve, sieve diamond special test screening examination. Test sieve screen surface materials are divided according to: Test sieves of metal wire cloth, perforated metal test sieves, electroformed mesh. Woven wire test sieves national standard GB / T6003.1-1997 production. Having a mesh size of 2.36mm-0.038mm basic screening test, in line with international standards ISO3310-1: 1990 R20 / 3, R20, R40 / 3 series, the screen is made of brass, bronze, stainless steel. 2.36um-100um test sieve using nickel processing factory can not only improve the accuracy of mesh, mesh deformation can be prevented, strong, wear-resistant and durable. Our aim is to filter screening qualified product testing sieve manufacturers, precision material has reached the requirements, to be done by measuring the test sieve. Standard test sieve professional manufacturers, communication screening inspection process with you. First, the control material particle size and particle size selected products is to ensure that important aspects of the production of technical indicators. Production of particle size greater than 6mm punched by steel or steel woven wire mesh sieve, and 6mm-0.045mm material is used a standard set of laboratory test sieve sieve model of particle size between 0.2mm-0.05mm, the using laboratory grade water or water decantation (also known as sedimentation analysis) method, referred to as water analysis, a more detailed analysis of the material used and the centrifuge microscope analysis.
