Aluminum hydroxide has a good whiteness, moderate refractive index, easy to process, with good flame retardant, smoke suppression and other characteristics, so that aluminum hydroxide as artificial stone is a very good filler.
Artificial stone products made of aluminum hydroxide raw materials have the following characteristics:
Light weight, low cost, easy processing, good color, good toughness, can achieve seamless stitching, and its manufacturing method is simple, short production cycle.Therefore, it quickly spreads to all parts of the world and is called a widely used building material.
At present, the world’s artificial stone with aluminum hydroxide annual demand of about 700,000 tons, and every year with about 10 percent of the rate of increase.More incomplete statistics, China’s artificial stone market annual demand in 1100 square meters above, and the current domestic artificial stone manufacturers’ production capacity is only 7 million square meters, huge market potential.
Due to the special sintering process and the deep desilication process of sodium chlorate solution, the alumina products produced by alkali lime sintering process have the characteristics of high whiteness and low iron content.Based on the rapid development of artificial stone industry, the filler aluminum hydroxide production line is being rapidly expanded to the market share at home and abroad.
The following is aluminum hydroxide manufacturers on the artificial stone with aluminum hydroxide three process production methods as follows:
(1) products produced by carbon separation method have slightly higher whiteness, higher pH value and SiO2% of products, and lower purity.Carbon separation production of products, the original grain size of the product is small, the grain surface is very rough, the crystal crystal is loose, the crystallization degree is poor, the pores are large, this is the reason for the high oil absorption rate of the product, with its production of artificial stone plate white.
(2) the whiteness of the products produced by the species classification method is slightly lower, the oil absorption rate is low, the pH value and the SiO2% of the products are relatively low, and the purity of the products is relatively high.The production of products, crystal growth is more complete, crystal grain surface is relatively clean, crystal crystals are relatively dense, the degree of crystallization is relatively good, the gap between the particles is small, this is the product oil absorption rate is low willing to you, with its production of artificial stone plate high strength.
(3) the products produced by the mixing method have the lowest oil absorption rate with the whiteness bottom.Blending method of products, both large particles of raw materials, and small particles of carbon filler, gradation, fill in full, make the aluminum hydroxide product of oil absorption rate is greatly reduced, at the same time, the viscosity of the product is low, less than 20000 eps, with its low cost, the production of artificial stone plate and customers do not need to allocate aluminum hydroxide filler, save Labour.
