Production technology of heavy calcium carbonate powder for breathable membranes
What is calcium carbonate used in breathable membranes? What are the production difficulties? What is a breathable membrane? A breathable film is microporous. It lets water vapor through but obstructs liquid water. It is primarily used to make health products. It also makes breathable, rainproof cloth and other products. It is used in various fields […]
Application of ultrafine grinding technology in food processing
Ultrafine grinding technology is a new technology developed in the past 20 years. Ultrafine grinding involves using force to crush solids. It does this by overcoming their internal cohesion. It crushes particles from above 3 mm to 10-25 microns. It was developed in the 1970s to adapt to modern times. A high-tech material processing technology […]
What is the use of modified calcium carbonate?
Calcium carbonate’s modification mechanism has two types. One is chemical action, the other is physical action. Surface chemical effects, such as substitution, polymerization, grafting and hydrolysis of functional groups. The filler causes surface effects like adsorption, coating, and infiltration. These effects happen at the phase interface. When the filler is completely wetted, it causes physical […]

Jet mill technology, an important method for preparing ultrafine powder, has become one of the preferred methods for developing high-performance micro powder materials. Characteristics of jet mill Jet mill, also known […]
How can calcium carbonate be used without adding fillers?
Superhydrophobic surfaces have a wide range of applications in a variety of fields such as waterproofing, anti-fog, self-cleaning, corrosion resistance, anti-icing, and flow resistance reduction due to their unique properties. Nevertheless, mass producing low-cost, low toxicity, easy to apply, and durable superhydrophobic coatings remains a challenge. In nature, there are a vast number of calcium […]
How do calcium carbonate performance parameters affect the plastic filler-modified masterbatch?
Calcium carbonate is the first choice of filler in plastic industry, widely used in plastic film, profiles, tubes, plastic knitting and artificial leather and other plastic industrial production, and can replace the expensive white pigment to play a certain role in whitening, to improve the surface luster of the product and the surface flatness and […]
Which calcium carbonate should I use for PVC modification?
Polyvinyl chloride (PVC) is a cheap and readily available polymer material with a wide range of applications in industries such as footwear, pipe fittings, wire, cable, and calendered films. However, the poor toughness and lack of thermal stability of pure PVC materials have limitations in many applications. Therefore, in many industries, PVC composites modified with […]
