Teach you how to quickly identify the quality of quartz stone

When decorating cabinets and other households that require high hardness, many families often choose quartz stone that is not scratched, used, or burnt as the main decorative material. However, the quality of quartz stone plates on the market is uneven. Consumers often don't know where to start when making choices. The following will introduce you to the method of quickly distinguishing the quality of quartz stone:

One: soak test with hydrochloric acid, etc. In order to maximize profits, some quartz stone manufacturers will doped calcium carbonate in the production of quartz stone raw materials. Calcium carbonate easily reacts with acid. If you choose this kind of countertop, the countertop will easily change in later use. Therefore, when purchasing, you can ask for a sample and soak it in dilute hydrochloric acid or other acidic liquids. If the product contains calcium carbonate, it will react with the acid and bubbles will appear.

Two: Test the permeability. The surface and internal structure of high-quality quartz stone are equally fine, dense and uniform, with low water absorption and strong penetration resistance; while inferior quartz stone is often limited to the appearance that looks similar, but the internal structure is loose and porous, with weak penetration resistance and water absorption. , Strong permeability. When purchasing, you can pour the soy sauce on the quartz stone plate to check whether it will bleed. Inferior quartz stone countertops will bleed in one day, but high-quality ones will not.

Three: Use a knife to check the wear resistance. The main component of quartz stone plate is silicon dioxide, which has high hardness. The quartz stone on the market is generally marked with a quartz content of more than 90%. Therefore, the possibility of fracture is very small, and it is relatively wear-resistant. Inferior quartz stone quartz sand is of poor quality, high impurity content, low surface hardness and easy to scratch. When purchasing, you can try to draw a line on the board with a knife.

Four: Check the heat resistance with fire. The resin used in inferior quartz stone is of poor quality and high content, and the heat resistance will also be reduced. So you can take advantage of this and burn the sample with a lighter etc. and see if there are burn marks left on it.
