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. Finally, it is washed with water, reinforced with colorants, filtered, dried and ground into powder.
The zinc content in the electrolytic zinc acid leaching residue in the leaching step is 5% to 35%. In the purification step, after the primary immersion liquid is added with ammonium persulfate for one oxidation, a polyacrylamide coagulant is added before the filtration separation. It is used for flocculation to produce arsenic and iron coprecipitation to remove harmful elements.
When it comes to purchasing lithopone, one of the best options available is lithopone B301 and B311. These high-quality lithopone products are widely used in various industries, including paint, coatings, plastics, and rubber. If you are looking for a reliable supplier of lithopone B301 and B311, then look no further than our factory.
For exterior wall paints, titanium dioxide's role becomes even more critical due to its excellent weather resistance. It safeguards the paint from UV degradation, preventing fading and chalking over time. This durability increases the lifespan of the paint, reducing the need for frequent repainting and maintenance, which is a significant advantage for construction and painting industries.
