How to identify the quality of fused quartz crucibles? Product quality depends on the quality of raw materials and processing technology, for quartz products so. Here, Xiaobian to tell you how to identify crucible quality.

First of all, the general quality of high melting fused quartz crucibles surface no pores, the thickness of about 15mm or more, the thickness of the standard, the bending resistance will be affected; therefore, this is the identification of crucible quality of the most significant standard.

Second, the hardness of quartz sand to 7, therefore, in the fused quartz crucibles with a knife or sharp metal objects, if left obvious scratches, then the quality of substandard. Cutting the surface along the edge, if there is collapse, the quality is unqualified. Quartz sand splicing gap is not obvious, the better the quality.

At present, the quartz crucibles due to poor quality of domestic quartz sand, so there are some flaws, but also by raw materials, equipment, technology and other aspects. In addition, China's quartz sand in the identification of the lack of professional inspection units, so some manufacturers of quartz sand quality is difficult to accurately grasp.
