China (Mainland)
Is the production of sulfuric acid method by sharp titanium type of titanium dioxide, has excellent optical properties and pigment performance, high purity, whiteness, covering power is strong and elimination of high and is easy to be scattered color vision. Apply to interior wall coating materials, indoor decorative paint, primer, plastic, rubber, paper, leather, etc. (note: recommended for paint, coating)
Sulfuric acid method with titanium dioxide industry sulfuric acid decomposition is made of titanium iron ore titanium solution, then the purification, hydrolysis made into hydration titanium dioxide (partial titanium acid), and further purification partial titanium acid to remove iron and other kinds of impurity calcined after dehydration, desulfurization, crystal into titanium dioxide makings, don't after disposal as a crushing goods, also can pass further grinding scattered, ShuiXuan post-processing, surface coating processing, dry, precision grinding be a commodity. This is the route of titanium dioxide production wet method, is sulfuric acid method of titanium dioxide; And in the route of law is LvHuaFa titanium dioxide different production process. Sulfuric acid method can produce sharp titanium type of titanium dioxide, also Harding type of titanium dioxide production rutile, has become a mature process route classic.
