The quality of quartz stone slab is reflected in which aspects specifically
What are the main differences in the quality of quartz stone slab ?The same quartz stone slab, but the quality has a huge difference. First,the quality of quartz stone raw materials will directly affect the quality of slab .The main filler quartz sand is divided into several grades, and the price is also several times different.In addition,if the content of quartz sand in the slab is less than 90%,it will directly affect quartz stone slab hardness. Second,the most important reason for affecting the quality is production equipment . At present, the quartz stone production process is mainly based on die-casting,and the tonnage of the press is the key to the quality of the slab.In the production of quartz stone,the force per square should be above 60 tons (the negative pressure should be above 98 under vacuum conditions), and the density of the slab should reach 2.6g/cm³. So how should we distinguish the quality of quartz slab ？ Actually,the...
