(Summary description)1. On the one hand, the purity level affects the color and appearance of the product, on the other hand, it will have an important impact on the mechanical properties and processing properties of the material. Generally, the lower the impurity content of heavy calcium carbonate, the better, and the higher the calcium carbonate content, the better.

1.

Generally, the lower the impurity content of heavy calcium carbonate, the better, and the higher the calcium carbonate content, the better.
2. Whiteness
The degree of whiteness will affect the color and appearance of the product; the higher the whiteness, the less and less the impact on the coloring power of the material; under the same performance conditions, the higher the whiteness has a competitive advantage in the market.
3. Particle size and distribution
The particle size and its distribution is an important index to measure the grade of heavy calcium carbonate products, and it mainly affects the mechanical properties of the material. The finer the particle size of the heavy calcium carbonate powder, the larger the specific surface area, and the greater the surface energy. The primary particles are easily agglomerated and added to the resin in the form of multi-aggregation. The dispersion is uneven and it is difficult to form a stable interface, which reduces the performance of the product. Therefore, heavy calcium for plastics requires appropriate fineness, not the finer the better.
4. Particle morphology and crystal form
The particle form of heavy calcium carbonate has a greater impact on the filling and modification of plastics. For example, fibrous and thin plates have an important impact on the mechanical strength of PVC composites, but have no effect on the molding performance. In contrast, spherical fillers can be improved The processing performance of the material, but it will reduce the mechanical strength of the material.
5. Moisture and low molecular weight substances
The moisture and low-molecular substances in heavy calcium carbonate will have a bad effect on the product, because moisture and low-molecular substances will cause defects and wrinkles on the surface of the product, and in severe cases, the product will be honeycombed or the material will be transported. Cause the bridge to break. It will affect the mechanical properties of the product and the appearance of the product.
The above are the factors that affect the use of heavy calcium carbonate introduced to you by the editor. I hope you can help you after reading it. If you have any questions, please contact us.
