Stone is a kind of building decoration material with a long history. With the continuous development of human society, the continuous improvement of the economic level, and the continuous progress of technology, the current quality of the artificial stone can be comparable to natural stone. In particular, artificial quartz stone can be said to be the perfect combination of technology and nature. It not only has the elegant appearance of natural stone, but also the noble temperament but also has powerful and unparalleled advantages. Quartz stone is colorful and rich, can be adjusted artificially, and lasts as new; it has a non-microporous structure and is resistant to dirt. As a new type of green building material, it can comprehensively utilize various resources, which can effectively inhibit the over-development of natural stone and protect The environment, the development of circular economy and low-carbon economy play a great role in promoting.

As the newest environmentally friendly composite material, quartz stone uses natural quartz stone particles, micro powder, and unsaturated polyester resin mixed with fillers and pigments. Under the action of a small amount of initiator, the quartz stone manufacturer uses special production equipment to die-cast the surface. The entire process is considered complete. Therefore, in addition to the selection and ratio of raw materials, the selection of production and processing equipment is a key factor in determining the quality of quartz stone plates.

The main filling materials of quartz stone are quartz sand, titanium dioxide, and toner, and the auxiliary materials are unsaturated resin, curing agent, and accelerator. The proportion of filler is 93%, among which the content of quartz sand is higher than 90%. That is to say, the higher the proportion of quartz stone plate filler (quartz sand), the better the quality. The impact of production equipment on quality is also very important. The vacuum value must be above -99 before pressing to avoid bubbles in the sheet. The pressing pressure cannot be less than 50 tons so that the density of the plate can reach the required value of 2.6g/m3, and the water absorption rate of the finished plate cannot exceed 0.02%.
