Now we are all not completely unfamiliar with the development of quartz stone plate, quartz stone has become the enterprise green ecological environmental protection engineering building decorative stone preferred surface material, belongs to artificial stone stone, because the plate contains up to 93% of quartz sand is called quartz stone by quartz stone manufacturers. However, at present, for China's quartz stone market economic chaos, quartz stone prices are also uneven, and even some students some social adverse effects of businesses in order to improve their own interests, the use of calcium powder instead of quartz sand content. Now some people in China should constantly ask Xiaobian, what is the difference between adding calcium powder and unadded calcium powder in the plate.

We all know what contact, quartz stone with wear-resistant, scratch resistance, heat resistance, impervious and many other advantages quickly occupied the decorative stone market. However, once the quartz stone plate is added with calcium powder, its quality will be greatly affected. The first thing that affects is the hardness of the board. The hardness of quartz stone is more than 6 degrees, and it is easy to scratch the hardness of 6 degrees. In addition, the acid and alkali resistance of the plate decreases, the high temperature resistance decreases, and if the plate is in contact with hot objects, it is easy to crack the plate.

How to identify the calcium powder in quartz stone plate? In fact, the identification method is very simple. Calcium is known to react with acids. But oxalic acid, household toilet cleaner or vinegar will do. If bubbles appear on the surface of the plate, it means that the plate contains calcium powder. Many businesses will give us experiments before purchase, but they will also use inspection after purchase, check the back of the plate jet code, ask for the manufacturer's warranty certificate and acid and alkali resistance test, to avoid bad businesses in the processing of the replacement of packaging.
