Nano calcium carbonate is also called ultrafine calcium carbonate. The standard name is ultrafine calcium carbonate. The most mature industry for the application of nano calcium carbonate is the plastics industry, which is mainly used in high-end plastic products. It can improve the rheological properties of plastic masterbatch and improve its formability. It can be used as a plastic filler to strengthen and toughen, improve the bending strength and bending elastic modulus, heat deformation temperature and dimensional stability of plastics, and also give plastics thermal hysteresis. Nano calcium carbonate is used in ink products to show excellent dispersibility and transparency, excellent gloss, excellent ink absorption and high drying properties. Nano calcium carbonate is used as an ink filler in resin-based inks, with good stability, high gloss, and does not affect the drying properties of printing inks. Strong adaptability and other advantages.
For plastics, ordinary calcium carbonate can only act as a filler. Among various non-metallic mineral powder materials, calcium carbonate has the widest range of use and the largest amount, accounting for more than 70% of the total amount of plastic additives. This is because calcium carbonate has the following advantages.
a. Cheap price. Calcium carbonate is the cheapest among various non-metallic mineral powder materials.
B. Good color, easy to color, and suitable for making various light-colored plastic products.
c. Low hardness. The Mohs hardness of calcium carbonate is only 3.0, which is much lower than the hardness of steel used in manufacturing and processing machinery and molds. Therefore, the wear of the equipment parts and molds in contact with the filled plastic is relatively light.
d. Good thermal stability and chemical stability. The thermal decomposition temperature of calcium carbonate is as high as 800℃, and the highest temperature of the plastic processing process does not exceed 300℃. Therefore, the decomposition reaction of calcium carbonate will not occur during the plastic processing process. Calcium carbonate is a strong alkali and weak acid salt. It has good chemical stability except when it encounters an acidic medium.
e. Easy to dry, no crystal water, and the adsorbed moisture can be removed by heating.
f. Non-toxic, tasteless, and non-irritating.
Only modified nano calcium carbonate filled in plastic products can play the role of an active agent and reinforcing agent in addition to fillers. Calcium carbonate is used as a filler and modified material. Modified nano calcium carbonate can increase the volume of plastic products, reduce costs, improve stability, hardness and rigidity, improve the processing performance of plastics, improve their heat resistance and density, improve the astigmatism, scratch resistance and smoothness of plastics, and can also improve the transparency, toughness, waterproofness and aging resistance of plastic films. It has obvious effects on the toughening effect of cylinder mouth impact strength and viscosity during mixing. Nano calcium carbonate can also improve the bending strength, bending elastic modulus, heat deformation temperature and dimensional stability of plastics, and at the same time give plastics thermal hysteresis from time to time.arbonate in plastics
