Ash ash chemical composition of raw materials is a plant fiber material in the inorganic salts, carbon paper use, mainly potassium, sodium, calcium, magnesium, sulfur, phosphorus, silicon salts. Wood ash are between 0.2 to 1.0%, ordinary carbon paper, grasses raw ash slightly higher. Usually paper ash content of the raw material has no special needs. However, when the production of electrical insulation paper, ash must be removed in order to achieve certain quality requirements. Grasses raw materials, Zhejiang carbonless paper, in particular straw ash high ash content of SiO2 high, causing difficulties alkali recovery. Recovery to reduce or eliminate the interference of silicon, which is a problem to be solved. Carbonless copy paper front "color layer" (Reactive Layer), or called the active layer. Color layer of the active ingredient is a color agent. Common reagent can be divided into three categories: clay type (ingredients such as), there are models (such as phenolic resin), aromatic carboxylic acid metal salt (such as zinc salicylate). The reagent is used as a proton donor. Zhejiang Jinzhou Paper Carbonless Paper _ _ non-carbon paper material provided by the Xinxiang City, New Materials Co., Ltd. Jinzhou.
