lithopone 28-30% quotes manufacturers
China's lithopone industry has been a significant player in the global market for several decades. Lithopone, also known as zinc sulfide white, is an inorganic pigment that finds applications in various industries such as coatings, plastics, rubber, and paper. This article provides a comprehensive guide to understanding the lithopone factory in China, including its history, production process, market trends, and environmental concerns.
Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.
Lithopone 28-30%, also known as B301 and B311, is a white pigment that has been widely used in various industries due to its excellent properties such as high brightness, good weather resistance, and chemical stability. This pigment is primarily composed of zinc sulfide (ZnS) and barium sulfate (BaSO4), which are combined in a specific ratio to achieve the desired color and performance.
One of the key trends in the wholesale TiO2 market is the shift towards sustainable and environmentally friendly production methods. Manufacturers are increasingly investing in research and development to develop eco-friendly production processes that reduce carbon emissions and minimize waste. This trend is driven by increasing regulatory pressure on industries to reduce their environmental impact and meet sustainability goals.
