Titanium White Production of sulfuric acid in the waste acid is mainly residue after sedimentation solution, the main ingredient is not decomposed iron ore of titanium, rutile, zircon, gangue, mud and sand, ferrous sulfate, sulfuric acid, and the free portion soluble titanium (TiOSO 4), is generally washed with water (neutralization with lime or), filtered, pressed dry made after inorganic waste, coal slag or blended with sub-brick.
The US Environmental Protection Agency stipulates that the allowable content of heavy metals in sludge fertilization is: Cd10mg/kg, Mo1000mg/kg, Hg10mg/kg, Ni200mg/kg, Pb1000mg/kg, Zn2000mg/kg, acid hydrolysis residue from a domestic plant (using Liangguang Mine) test The results were lower than this standard: Fe 2 O 3 14.9%, A1 2 O 3 22.93% CaO 8.47%, MgO 6.3%, CdO 2.8 mg / kg, Mo 36.2 mg / kg, PbO4 3.5 mg / kg, NiO55. 7 mg/kg, ZnO 49.4 mg/kg, and Hg were absent.
The acid-decomposed waste residue can also be returned to the ilmenite for re-acidification. In China, there have been examples of re-acidification of the acid-decomposed waste residue in the factory, but too much application affects the whiteness of the product, and TiO in the slag (dry basis) When the content is less than 40%, there is no need to return to continue use. Recently, it has been reported that Saatchi, Germany, has about 50% of acid-decomposed waste residue containing TiO 2 , which is blown into a steel-making furnace in a steel-making plant, and finally sintered on the inner wall of the furnace, which can greatly extend the steel-making furnace refractory brick. The service life of the lining.
CMC Carboxy Methyl Cellulose used as Wet-end additive,smoothing agent,surface-sizing agent in defiberination optimization.wet end.surface-sizing.
Hansstar CMC add in all parts of Papermaking process.
Strengthen water retention, improve the paint rheology,provide the carrier for whitening agent and
brightening agent in coated preparation process;Take chemical effect and enhance cohesion between the fibers,improve paper strength under wet-end process;Enhance the lubrication property between fibers,protect the fiber from over cutting,boost fiber swell up, easy beating,reduce energy consumption and save the cost in defibrination optimization process;In surface-sizing process, CMC is with excellent film form and entire film transferability and it also can form a good closure and oil-resistance on paper and paperboard surface. Furthermore, CMC is a dispersant which makes the entire sizing material or coating material enter into the stable and uniform system,reach good sizing effect.
