Below 20% substitution, it is recommended to replace 1 kg of TiO2 with 1 kg of lithopone supplier.
The reaction liquid is filtered through plate and frame pressure to obtain lithopone in the form of a filter cake with a moisture content of no more than 45%. It is then roasted in a drying furnace to change the crystal form of lithopone, and is then pickled with sulfuric acid at a temperature of 80°C.
