How to check the quality of quartz stone countertops?
1. Avoid some unscrupulous merchants to maximize their profits by adding calcium powder to the raw materials for filling. Oxalic acid can be used for testing. Take a small amount of oxalic acid and drip it into the surface of the board. If bubbles appear, it means that the board contains calcium powder. The test time should not exceed half an hour. After the test, it should be cleaned and dried with clean water or soapy water.
2. Detect the anti-permeability ability. The water absorption rate of the quartz stone plate is 0.02%, and the density of the plate can reach 2.6g m3. In addition, there is no pores and small cracks on the surface, and the possibility of liquid penetration is very small. A small amount of soy sauce can be dropped on the surface of the board and cleaned within 24 hours. If it penetrates into the board, it is unqualified.
3. For high temperature resistance testing, you can use a stainless steel container to fill boiling water or light a cigarette on the surface of the board, and place it for about half an hour. If the board is discolored and cannot be cleaned with water, it is unqualified.
