Quartz stone must be known to everyone. It "dominates" the first place on the cabinet countertop with its advantages of wear resistance, scratch resistance, high temperature resistance, impermeability, non-toxicity, and no radiation. As the production technology of prefab quartz countertops manufacturers continues to mature, the output is also rising. Quartz stone has also been fully developed from being the only favorite on the countertop to a decorative stone, and is now being used more on the ground and walls. Quartz stone is a new artificial stone, which is also artificially synthesized.

The production raw materials of prefab quartz countertops are synthesized from quartz sand, resin, curing agent, coupling agent, and natural pigments. The content of quartz sand alone accounts for more than 93%. Anyone who knows quartz stone very well knows that quartz sand can be divided into pickling sand and ordinary sand. What are the advantages of pickling sand? Pickling quartz sand is also called refined quartz sand, SiO2≥99-99.5% Fe2O3≤0.02-0.015%, pickling is to soak the carrier with 6mol/L hydrochloric acid for 2 hours or concentrated hydrochloric acid for 30 minutes, filter, and wash with water until medium sex, dry. Pickling can remove impurities such as iron, aluminum, calcium, and magnesium on the surface. Commonly used acids for pickling are: hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, and hydrofluoric acid.

It can be said that pickling sand can fundamentally eliminate harmful substances and possible radiation sources to the human body. The use of pickling sand can omit manual removal of impurities before plate production, but some brand companies still have a removal process for safety. Pickling sand is also called A-grade sand in the industry, which is one of the reasons for the high price of quartz stone.
