粒度检验是控制磨料粒度质量的最重要的工作之一;但单靠粒度检验还不能说是对产品质量的一种积极的控制办法,因为它只是所谓的“事后检查”;积极控制磨料粘度质量的办法应该是推行全面质量管理,通过对磨料粒度的检验利用概率与统计的方法找出既能保证产品质量而又比较合理的最佳磨料筛分生产工艺。再通过生产过程中的抽样检查,根据测定结 Particle size testing is one of the most important tasks in controlling the particle size of abrasives; however, particle size testing alone cannot be said to be a positive control over product quality because it is only a so-called “post-mortem inspection”; active control of abrasive viscosity quality The approach should be to implement total quality management. Through the inspection of the abrasive particle size, a probability and statistics method is used to find out the best abrasive screening process that can ensure product quality and is relatively reasonable. Then through the sampling inspection in the production process, according to the determination of the knot
