Ultra-active light calcium carbonate

I'd be happy to chat with you! What would you like to talk about?Jiangxi Ultrafine Calcium Carbonate ManufacturerThe Chinese character "的" is a possessive particle or modifier, often equivalent to "'s" or "of" in English. It can also be used to form adjectives or indicate a descriptive relationship. In different contexts, it may be translated as "of," "'s," or omitted depending on the sentence structure.What are the uses and characteristics of super-active light calcium carbonate?
Active lightweight ultrafine calcium carbonate, as a high-filling-volumeFillers are widely used in industries such as rubber, plastics, plastic-steel doors and windows, PVC cable materials, coatings, pipes, tires, shoe soles, polyethylene blown film, sealing strips, fiberglass products, cable wrapping cloth, papermaking, building materials, printing inks, daily chemicals, textiles, feed, and food additives.
1、Jiangxi Ultrafine Calcium Carbonate ManufacturerIn plastics, it can improve the dimensional stability, hardness, and rigidity of plastic products, enhance the processing performance of plastics, as well as the heat resistance and light-diffusing properties of their finished products.
2. When used as a filler in rubber, it can increase volume, reduce costs, and improve processing and vulcanization properties.
3. In papermaking, it can be used as a filler for paper, a white pigment for coated paper, a filler for calcium plastic paper, etc.;
4. In coatings, it acts as a filler and provides a skeletal structure, hence it is referred to as a "body pigment." In oil-based coatings, the filling amount can reach 10–50%, while in water-based coatings, the filling amount can reach 10–20%.Activated light calcium carbonate is used as the base material, and is processed through surface modification and activation of inorganic powder using multifunctional surfactants and composite processing aids. The modified calcium carbonate powder forms a cladding structure on its surface, which significantly improves its dispersibility and affinity in polymer matrices such as polyolefins. Additionally, it creates interfacial interactions with the polymer matrix, thereby enhancing the impact strength of the final product. It is an excellent performance-enhancing incremental filler additive, typically used at a filling amount of 30.Some products even exceed 100 units.
Characteristics of Activated Light Calcium Carbonate
(1) Appearance: white powder, odorlessNon-flammable, non-explosive, low refractive index, easy to color, insoluble in water, and stable in air.
(2) After activation treatment, the product undergoes a change in molecular structure, achieves uniform particle size distribution, and exhibits strong hydrophobicity.
(3) It features high whiteness, good fluidity, excellent gloss, uniform dispersion, and high filling capacity. It also possesses good lubricity, fluidity, dispersibility, and organic properties.

(4) It has strong intermolecular affinity with rubber and plastics, and its filling amount can be 2 to 5 times or even several times higher than that of ordinary calcium carbonate, significantly reducing overall production costs.

(5) Low oil absorption, high whiteness, high elongation, and its uniqueThe metal stripping property and significant lubrication effect can also enhance the surface brightness, wear resistance, and impact strength of the product.

(6) It can reduce wear on processing machinery, improve product processing techniques, enhance product performance, and provide a good reinforcing effect.

(7) When applied in coatings, this product can increase solid filling capacity, reduce viscosity, and simultaneously lower the baking temperature, shorten the baking time, improve product quality, and reduce production costs, resulting in significant economic benefits.
(8) Fluidity: Due to the surface of activated calcium carbonate products being coated with organic active agent molecules of lower surface tension, their specific surface energy is lower than that of non-activated products. This reduces the viscous resistance between particles and improves the flowability of the particles. As a result, the powder exhibits fluidity similar to that of a liquid.
(9) Dispersibility: The good flowability of active products indicates differences in dispersion. Due to their excellent dispersion, active calcium products exhibit good compatibility and dispersibility with the base material during application. The particles also have strong penetration ability, making them prone to forming dust. Products packaged in ordinary woven bags generate significant dust during loading, unloading, and use.
