Aluminum hydroxide industry known as alumina hydrate, because of its good whiteness, refractive ratio moderate, easy to process, with good flame retardant, smoke suppression performance, so that aluminum hydroxide as a very good artificial stone filler.
The artificial stone products made from aluminum hydroxide have the following characteristics:
Light weight, low cost, easy to process, good color, good toughness, seamless splicing can be achieved, and its manufacturing method is simple, short production cycle.Therefore, it quickly spread to all parts of the world, known as a kind of widely used building materials.
At present, the world’s annual demand for aluminum hydroxide for artificial stone is about 700,000 tons, and the annual growth rate is about 10%.More incomplete statistics, China’s annual demand for artificial stone market in 1100 square meters, and the current domestic production capacity of artificial stone manufacturers is only 7 million square meters, the market potential is huge.
Due to the special sintering process and the deep desilication process of sodium chlorate solution in the production of alumina by caustic lime sintering process, the aluminum hydroxide products produced have the characteristics of high whiteness and low iron content, and have unique advantages.Based on the rapid development of the artificial stone industry, the production line of aluminum hydroxide filler is being expanded rapidly to expand the market share at home and abroad.
The following is the manufacturer of aluminum hydroxide for artificial stone with the production of aluminum hydroxide three processes are introduced as follows:
(1) the products produced by carbon separation have slightly higher whiteness, higher pH value and higher SiO2%, and lower purity.Carbon method of production of the product, the original grain size of the product is small, the grain surface is very rough, the crystal crystal is more loose, the degree of crystallization is poor, the porosity is larger, this is the product oil absorption rate is higher, with its production of artificial stone plate whiteness is high.
(2) the products produced by classification method have lower whiteness, lower oil absorption rate, lower pH value, lower SiO2% of the products and higher purity.Seed division method production products, crystal development is more perfect, crystal particle surface is more bright and clean, crystal crystal is more dense, crystal degree is better, the gap between the particles is small, this is the product oil absorption rate is low would like you, with its production of artificial stone plate strength.
(3) products produced by the mixing method have the lowest oil absorption and the lowest whiteness.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.
