WhatsApp: +86 18838072829Abrasion characteristics of any material are a function of hardness, concentration and particle size. Hardness is typically measured on the Mohs scale, where a diamond is 10 and talc is 1 (Figure 1). A higher Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs hardness of 3.
WhatsApp: +86 18838072829Ground calcium carbonate used in the manufacturing of roofing, flooring, and other building materials. Ground calcium carbonate is often used to increase durability and reduce costs by displacing or "extending" other raw materials that are more expensive. It is the ideal raw material as it has low absorption qualities, consistent particle size distribution and color.
WhatsApp: +86 18838072829Natural calcium carbonate is hydrophilic in nature and is just as invasive to organic elements as polymers. However, a cheap white filler has been forced by the plastics industry. If you mix ground calcium carbonate with plastic, the high energy of the particles creates friction. Fortunately, to reduce this resistance, we can change the surface ...
WhatsApp: +86 18838072829The main operation principle of quicklime production plant is the decomposition or calcination of limestone which contains mainly calcium carbonate. In the calcination process, when calcium carbonate is heated with high but appropriate temperature, the calcium carbonate decomposes into quicklime(CaO) and carbon dioxide(CO₂).
