Stone paper production process and process

Zero benzene, zero formaldehyde wall paper, the product has no harmful substances such as heavy metals, no odor, moisture-proof, flame retardant and antibacterial and other functional properties, the production of synthetic paper surface treatment, slitting, coating, is synthetic paper. Some of the process flow adopts special master batch and calendering stage production, and some imported production equipment also adopts continuous one-time molding process.

The specific technological process of stone paper is as follows: Grind ore containing more than 95% calcium carbonate into superfine powder of high calcium 1500-2500 mesh in a limestone mine; 1. Formula: calcium carbonate, polyethylene, and adhesive are its main components, but It is also necessary to add some small materials such as auxiliary materials such as lubricants, coupling agents, accelerators and other auxiliary materials for granulation to meet the requirements of production and use. Any thickness you want can range from 80-600um.

Stone paper production process: granulation (material handling) --> papermaking (drool stretching) --> coating (paper surface treatment)

Stone paper can be made into decorative wallpaper, cartons, cartons, coated paper, cigarette paper, labels, cards, advertising decoration paper, postage paper, etc.

Special paper: paper for field work, paper for underwater work, paper for mine work, special paper for military use

The cost of stone paper is 20-30% lower than that of alternative paper, making it highly competitive
