Artificial marble is durable consumer goods directly to the public, more strict with the quality of products, and as the main raw material of artificial marble aluminum hydroxide in the artificial marble content more than 60% (mass percent), aluminum hydroxide directly influences the quality of artificial marble processing technology and product quality of aluminum hydroxide crystal morphology impurity moisture and tone is a key factor affecting the quality of artificial marble dense crystal structure forms tend to be spherical aluminum hydroxide to join after polymer viscosity is low, add in artificial marble quantity is high, reduce the production cost of artificial marbleCompared with advanced foreign products, the crystal structures of domestic aluminum hydroxide filler is relatively loose, oil absorption rate is high, poor filling properties of the products to reduce moisture content can promote aluminum hydroxide filler with polymer to better reduce the impurity content and shorten curing time, try to improve the whiteness and maintain color stability, to improve the quality of artificial marble level at present, the domestic aluminum hydroxide has been able to better control the moisture content, the prominent problem is much higher viscosity chromatism volatile impurities, the product of oil absorption rate is higher, the product of the filling performance is poorer, after filling resin viscosity is big, not easy to disperse, affect the compound after the appearance of the productMechanical properties etc. In addition, due to domestic aluminum hydroxide level is the use of metallurgical production special aluminum hydroxide, alumina production process grafting volatility production technology, product quality stability is bad, in addition, the lack of effective domestic product homogenization method, different batch products between the physical and chemical performance there is a big fluctuation, the production and product performance to downstream users bring some adverse effects
