The rapid development of society, makes the application of quartz sand in each big industry in the middle, but pay more attention to quality requirements higher quartz sand in the world do have a unified standard requirements identification standard, we all know that product quality is good bad is determined by its raw material, the high purity quartz sand quality stand fall of how to identify?

First of all, there is no porosity on the surface of high purity quartz sand with high quality, the thickness is about more than 15mm, the flexural resistance will be affected if the thickness is up to standard.

Secondly, the hardness of high purity quartz sand reaches 7, it can be seen in the quartz sand with a knife sharp metal scratching, if there are obvious scratches obviously quartz sand is qualified, about the cutting surface along the collapse grain is qualified quartz sand, quartz sand splicing gap is obvious the better the quality.

At present, the quality of domestic high purity quartz sand is poor, because of the influence of raw materials, equipment, technology other aspects, the country is less in the quartz sand identification inspection unit, so that the carelessness of factory workers is the reason that affects the quality of quartz sand.

Choose buy high purity quartz sand, identify qualified manufacturers is the key, Jiangsu Jingrui quartz Industrial Development Institute professional high purity quartz sand R & D base, to provide quality quartz products, such as related questions welcome to inquire!
