Heavy calcium carbonate products should be used in papermaking, rubber and plastic industries. Its application range is relatively wide. So, in which industries is it used? Do friends understand? Let's take a brief look with the editor below!

1. Papermaking: The demand for calcium carbonate in papermaking is also increasing. Light calcium carbonate loses its sizing appearance due to high oil absorption and large consumption of glue. In addition, light calcium carbonate has strong water retention. Increased in machine paper, paper strength is lower than heavy calcium carbonate.

But for the production of cigarette paper, light calcium carbonate is better than heavy calcium carbonate. The calcium carbonate used in cigarette paper at home and abroad is mainly light calcium carbonate, especially spindle-shaped calcium carbonate. Because its crystal form determines the accumulation of particles and interspersed together, it will have a bridging effect. It is looser, has better opacity and whiteness. It is a good choice for calcium carbonate for cigarette paper.

2. Plastics: Ordinary light calcium carbonate is too light in some plastic calculations due to its high oil absorption value, and it is difficult to mix and increase the amount. It can only be used as a general extender. Therefore, in plastic woven products, pipes, injection molding or hollow products, heavy calcium carbonate is widely used.

3. Rubber: Light calcium carbonate enterprises can increase the volume of rubber, improve rubber vulcanization performance, and play a role of semi-reinforcement or reinforcement due to the small particle size and large settlement volume of light calcium carbonate enterprises.

4. Others: For equipment coatings, putty, felt packaging, feed, etc., heavy calcium carbonate should be used because the particle size is relatively coarse and meets the requirements.

The above is the entire content of the application of heavy calcium carbonate in various industries introduced by the editor. I hope you can have a better understanding of it after reading it.

Shandong Shenxing Calcium Industry Technology Co., Ltd. was established in 2017. As a calcium carbonate manufacturer and a manufacturer of heavy calcium carbonate, the company’s main products are heavy calcium carbonate, calcium carbonate powder, calcium carbonate, etc. If you have a demand for this, Welcome to consult us, we sincerely look forward to cooperating with you.
