METHOD OF TREATMENT OF MINERAL MATERIALS BY AMPHOTERIC POLYMERS, MINERAL MATERIALS OBTAINED, THEIR USE AS AN AGENT TO REDUCE COLLOIDAL QUANTITIES IN THE PRODUCTION OF STEAM

摘要

The invention relates firstly to a new mineral material treatment method using at least one amphoteric polymer, to make these mineral materials effective as an agent to reduce the quantity of natural and organic colloids in the manufacturing process for a sheet of paper. The second purpose of the invention is the treated mineral materials obtained using the method according to the invention. The third, fourth and fifth purposes of the invention consist of dry powders, aqueous suspensions and pellets of treated mineral materials obtained using the method according to the invention. A final purpose of the invention is the use of mineral materials treated using the method according to the invention as an agent to reduce the quantity of natural and organic colloids in the paper sheet manufacturing process. ® KIPO & WIPO 2009
