Main factors affecting the quality of quartz stone plates
Stone is a kind of building decoration material with a long history. With the continuous development of human society, the continuous improvement of economic level and the continuous improvement of science and technology, the quality of artificial stone has been 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, the temperament of nobles, but also has powerful and unparalleled advantages. Quartz stone is rich in color, can be artificially controlled, lasting as new; has no 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 excessive development of natural stone and protect it. The environment, the development of circular economy, low-carbon economy has played a significant role in promoting.
As the latest environmentally friendly composite material, quartz stone is made of natural quartz stone particles, micro-powder and unsaturated polyester resin mixed with filler and pigment. Under the action of a small amount of initiator, it is die-cast and surface-formed by quartz stone manufacturers using special production equipment. Processing, the entire process is completed. Therefore, in addition to the choice and ratio of raw materials, the choice of production and processing equipment is a key factor in determining the quality of quartz stone sheets.
Quartz stone is mainly filled with quartz sand, titanium dioxide and toner. The supplementary materials are unsaturated resin, curing agent and accelerator. The proportion of the filler is 93%, and the content of the quartz sand is higher than 90%, that is to say, the higher the proportion of the quartz stone plate filler (quartz sand), the better the quality. The impact of production equipment on quality is also very important. The vacuum value before pressing should reach -99 or above to avoid bubbles on the board. The pressing pressure should not be less than 50 tons, so that the density of the sheet can reach the required value of 2.6 g / m3, and the water absorption of the finished sheet can not exceed 0.02%.
