Heavy calcium carbonate and light calcium carbonate are widely used powder fillers in the plastics industry. China's annual output of plastic products has exceeded 10000 tons. According to the calculation that plastic powder filler accounts for 8% of the total plastic products and calcium carbonate accounts for 70% of the total amount of various powder fillers, China's plastic industry uses about 5.7 million tons of calcium carbonate of various specifications every year. Calcium carbonate has become an incremental material in the plastic processing industry due to its low price, easy to use, and low side effects, which has brought huge business opportunities to the calcium carbonate industry.
Calcium carbonate can not only reduce the raw material cost of plastic products, but also improve some properties of plastic materials. In recent years, gratifying achievements have been made. The research results of many universities and scientific research institutions show that if used properly, different types of calcium carbonate can significantly improve the performance of matrix plastics. However, the difference between light calcium carbonate and heavy calcium carbonate has always plagued most users.
The calcium carbonate industry has a wide range of uses in all walks of life, with high quality and low price, so its uses can be many, so what we are going to talk about today is some knowledge of light calcium carbonate. Only when we understand it can we make better use of it, thus bringing better promotion and help to our products.
Heavy calcium carbonate is a very important inorganic mineral, not only in industry, but also in our lives everywhere. Geologically, ground calcium carbonate is a natural mineral of the earth's crust. There are three types of ground calcium carbonate deposits: limestone, chalk and marble. According to research by relevant departments, the distribution area of carbonate rocks (including heavy calcium carbonate and dolomite) in the world is 5.34 million square kilometers, accounting for 4% of the earth's land surface area. China's carbonate rock area of 3.44 million square kilometers, accounting for 64% of the world.
