A method for calcium carbonate retention reconstituted tobacco paper making process to improve the

The present invention relates to a method of calcium carbonate reconstituted tobacco paper making process to improve the retention, which will be added to the pulp fiber slurry of calcium carbonate certain freeness of the pulp fiber slurry with the calcium carbonate to form a composite full adsorption It was carried out with cationic starch wrapped to form larger flocs mer, respectively, and then with a surfactant, a crosslinking agent for the flocculation stability and surface modification treatment by means of the multiple composite retention and drainage system will be modified after by papermaking tobacco mixed with calcium carbonate slurry, pressing, coating, drying, slitting into reconstituted tobacco. Bonding force of calcium carbonate slurry after modification using the present method of enhancing, and easy loss, the modified calcium carbonate in the retention rate of reconstituted tobacco.
