                                                Abrasion Degree *2.2%The mineral fibre HP***0A used in papermaking has unique physical and chemical performances, namely high whiteness, high dielectric property, resistance to acids and bases and heat-resistance, which is processed with natural mineral fibre- wollastonite as its basic raw material and its chemical formula is CaSiO3. Net structure can be formed after mineral fibre is interweaved with plant fibre by special processing, and then plant/mineral fibre composite fibrous material is obtained. This material can be used in papermaking by replacing part of paper pulp made of plant fibres and the production cost will be considerably decreased when the paper performance is improved. It’s more appropriate for high-speed paper machine.
