衡量硬质纤维板的质量好坏,在物理力学性能方面有三个主要指标,即静曲强度、容积重、吸水率。根据LY110—62规定,检验人员可以在十几分钟时间内测知一批产品的静曲强度和容积重。但吸水率的测定,必须把试件在水中浸泡24小时之后方可测定,所以当班的生产指挥员和工人师付就无法在8小时内知道自己产品的质量情况,出现了次品也就无法及时发现和纠正。为了解决这个问题,我们进行了缩短试件浸泡时间的吸水率测定方法的试验。经过一年
Measuring the quality of hardboard is good or bad, there are three main indicators in physical and mechanical properties, namely, static bending strength, bulk density, water absorption. According to the provisions of LY110-62, inspectors can detect a batch of products in a dozen minutes of static bending strength and volumetric weight. However, the determination of water absorption, the specimen must be soaked in water for 24 hours before the determination, so on duty production commanders and workers can not pay within 8 hours to know the quality of their products, there will be no defective Find and correct in time. In order to solve this problem, we conducted a test that shortens the method of determining the water absorption of the sample soaking time. After a year
