Chemical performance ① Water: Paper contains at 100 ~ 105 ℃ can evaporate moisture by weight, Xinxiang City, NCR, to indicate the percentage of the paper weight. ② Ash: paper by weight of the residue after burning pattern oven dry sample weight expressed as a percentage. ③pH value: pattern was immersed in distilled water for 95 ~ 100 ℃ for 1 hour, to obtain a water extract pH. The chemical properties of indicators is particularly important for electrical and technical paper. Color-layer coating is added adhesives goal is to combine the color agent and Paper, NCR triple, to enhance its bonding strength between layers, NCR, in order to prevent delamination and dusting. The amount of adhesive is important, the amount is excessive, the coating reagent may all be covered with adhesive, making color performance degradation, wholesale NCR, increase the cost of a paper. Too small amount of adhesive, although the color is better, but the combination of strength and reagent paper drop, easy to produce powder out, leaving the paper delamination lose value. Other additives include defoamers, preservatives and the like. NCR characteristics, NCR, Jinzhou Paper provided by Xinxiang City Jinzhou New Materials Co., Ltd. Xinxiang City, New Materials Co., Ltd. Jinzhou (www.hnjinzhou.com) strong, credible, in Xinxiang of paper and paper processing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Jinzhou Paper into the brilliant and you work for a better future!
