Kitchen decoration is essential in home improvement, especially the choice of materials such as cabinets, door panels, countertops, etc. The cabinet should be environmentally friendly, the door panels should be corrosion resistant, and the countertops should be strong. This is the basic common sense of choice.
At present, the mainstream materials for countertops are quartz stone, artificial stone and natural stone, and the usage rate of stainless steel is gradually reduced. Simply put, artificial stone is made of resin, aluminum powder (calcium powder), pigment and curing agent; quartz stone is quartz crystal plus resin and other additives artificially synthesized by high pressure and high temperature, because the plate contains up to 93% of the quartz sand solid is called quartz stone, and it is also the most expensive product.
Since the price of quartz stone is higher than other stone materials, some bad businesses will add calcium carbonate in order to reduce costs. Calcium carbonate is the main component of limestone and has certain corrosiveness. If the food is in contact with a table containing more calcium carbonate for a long time, it will cause certain pollution, and people will have certain influence on the digestive tract after eating.
How to distinguish the quartz powder containing calcium powder? In fact, the method of identification is very simple. As we all know, calcium reacts with acid to cause a chemical reaction. You can use oxalic acid or the toilet bowl and vinegar in your home. If there are bubbles on the surface of the board, it means that the board contains calcium powder.
