Pigments are indispensable raw materials in the production process of coatings and are divided into organic and inorganic. Chemically-reactive synthetic inorganic pigments include various metal oxides, chromates, carbonates, sulfates, and sulphides, such as aluminum powder, copper powder, carbon black, zinc white, and titanium dioxide, all of which belong to the category of inorganic pigments. . Inorganic pigments are widely used in coatings, plastics, synthetic fibers, rubber, construction materials, cultural and educational supplies, paints, inks, paper and other fields. It is also the largest and most widely used pigment in the coating industry.
With the recovery of the global economy, domestic and foreign construction and building materials, paints, paints, plastics, inks and other industries have experienced rapid growth, and the demand for inorganic pigments has also rapidly increased. It is understood that in 2010 China's total production of paint was 9.666 million tons, an increase of 22.8% year-on-year; China's total annual production of pigments in 2010 was approximately 2,247,640 tons, an increase of 22% year-on-year; in 2011, the national paint output reached 1079.5 tons, a year-on-year increase. 16.44%. With the rapid development of the paint industry, inorganic pigments as one of its main raw materials have made considerable progress, with titanium dioxide and iron oxide accounting for the largest proportion.
During the “Twelfth Five-Year Plan†period, the country will implement total control of heavy metals and other characteristic pollutants in some regions. With the increasingly stringent national environmental protection regulations and the growing demand for environmentally-friendly inorganic pigments in downstream areas, the “Twelfth Five-Year Plan†period The development, production and application of environment-friendly inorganic pigments will surely make great progress. At present, under the strict environmental protection regulations, many countries are innocuous and environmentally friendly inorganic pigments that can replace traditional lead and cadmium pigments are popular. Domestically, we are also actively developing environmentally-friendly inorganic pigments, which have brought hope to downstream industry applications and the industrial outlook is expected to expire.
