The main raw material for papermaking plant fiber raw materials, in addition to containing cellulose, hemicellulose, lignin three main components, there are fewer components other content, such as resin, ash and the like. In addition to sodium and other auxiliary ingredients. In addition to the paper plant fiber, also need to add different fillers based on different paper stocks. Such as copper-based antimicrobial paper is to copper ions recombine polyacrylonitrile (commonly known as: acrylic) on the first monomer acrylonitrile, polyacrylonitrile composite fiber obtained, and then added to a plant with modified acrylic fibers, with uses a variety of paper, can be obtained anti-bacterial paper. The 2010 environmental protection is growing, paper mills have launched with different percentages of recycled content paper, there is a 100% recycled paper, also adding only 50 percent recycled content of paper, NCR plant, suitable for different customer It needs. Recycled paper from waste paper, after sterilization, the pulping process may be re-used and so on. The purpose pulping systems are completely disintegrated waste paper without damaging the fibers, the non-paper components are not broken. ① quantitative physical properties: Weight per square meter, in g / m expressed. Culture printing paper as quantitative usually 32 ~ 80g / m, NCR, quantitative cardboard is generally 200 ~ 400g / m. ② Thickness: between the two measuring plates, applying pressure 100kPa, direct measurement of the thickness, in mm. ③ tightness: indicates the degree of tightness of the paper structure, the weight per cubic centimeter of paper to g / c mean?. The same quantity of paper, large paper thickness on the loose. ④ porosity and permeability: Fair paper contains 70% porosity. Air permeability is a certain area of ??the paper in a certain vacuum degree, Henan NCR, the amount of air per minute through the air or through a certain amount of time, NCR wholesale, respectively, ml / min or s / 100ml expressed . ⑤ expansion rate: After soaking the paper or at different temperatures after humidification or dehumidification, change the paper size relative to the size of the increase or decrease of the percentage of the original sample sizes are indicated. Offset paper for expansion rate higher. ⑥ strength: Paper by external force, to achieve a number of specific values ??reflected the point of failure. There are tensile strength and elongation at break, bursting strength, folding, tearing and stiffness. The strength index is particularly important for wrapping paper. ⑦ ignition point: generally 130 ~ 255.5 ℃.
