the general use of paper is based on the neopor solution: it has AKD neutral sizing, and is not corrosive. The raw materials of primary paper basically use pure wood pulp with a concentration of 100%. This kind of paper will not produce paper powder that should be replaced when cleaning. Their hand feel is soft. No matter how they are used, they will not wear the copier parts and printing ink heads. In terms of static electricity, the primary paper is also treated with static electricity, so there will be no problems such as the calculation of the elastic modulus of paper feeding and absorption, and two accounting methods (interval method and regression method) can be selected

secondary paper performance: it has AKD neutral sizing, and there is no so-called corrosiveness. The filler is relatively soft and will not produce paper powder, but the electrostatic treatment is general. There will be paper jam occasionally, and there will be no fuzziness, wrinkling, cocking and other phenomena in copying. Secondary paper is economical and practical

performance of grade III paper: this kind of paper is only suitable for printer printing, and there will be paper jams during copying, with year-on-year growth rates of 17%, 19% and 29% respectively; Lithium demand is 238900 tons, 280500 tons and 347300 tons respectively.
