The ringing stone paper of our company is made of grindstone as the main raw material, plus 15% polyethylene and 5% adhesive. This kind of paper is waterproof, strong and not easy to burn. The most important thing is that it doesn't need to cut down trees to make paper, which is very environmentally friendly.

Paper made of stone looks nothing special on the outside, but you can write in the water, take it out after ten minutes and wipe it with your hands. Not only will the words not faint, but you can also dry the water before writing. If you burn stone paper and plain paper at the same time, the plain paper will burn out at once, but the fire of stone paper will gradually become smaller and finally go out.

Stone papermaking technology was invented by Hong Kong Longmeng Technology Paper Industry, and has been patented in many countries in the world. Now it is used in notebooks, paper bags and lunch boxes. In an era when people pay more and more attention to environmental protection, this new technology will attract more and more attention from the world.

Now I want to know the following questions, please help me answer them:

1 can inorganic mineral powder (stone powder) be replaced by calcium carbonate?

Resin is made of PE, can it be replaced by PVC?

If it is feasible to use PVC and calcium carbonate, how can the proportion achieve the effect of stone paper now? In response to the call for energy conservation and emission reduction, we will vigorously support the production and research of "stone paper". After the transformation of the ordinary mill, the ultra-fine mill YLM 1 120 was developed, and the fineness can be adjusted arbitrarily between 200 and 850. The mill has low power and high output!
