Acicular wollastonite: wollastonite mineral fiber filler for papermaking, is a new type of papermaking raw material, which can partially replace wood pulp, straw pulp, waste paper pulp and other papermaking raw materials in packaging paper and cultural paper. It can effectively improve the physical strength of the finished paper, improve the whiteness, opacity, stiffness and flatness of the paper, improve the covering rate and surface properties of the paper, and at the same time, the retention rate of wollastonite mineral fiber is as high as 80%. To meet the requirements of the papermaking process, it also greatly improves the utilization rate of materials, reduces the production cost of paper products, and reduces the amount of pollutant emissions.
Superfine talc powder: The use of talc powder can improve the evenness, flexibility, gloss, smoothness and ink absorption of the paper sheet, and improve the printing and writing properties of the paper sheet; the produced paper is smooth, delicate, and can save money raw materials, improve the service life of paper. Widely used in medium and high-grade electrostatic copy paper, double-adhesive paper, coated paper, writing paper and other cultural papers; carbonless copy paper, thermal base paper, aluminum foil lining paper, decorative base paper, industrial paper and other special papers.
