Abstract
The present invention discloses a method for making pulp and paper with young poplars. The whole trunks of young poplars are steamed and boiled for making pulp by a KP+AQ method, the fine pulp rate reaches 41%, the Kappa number reaches 16.2, pulp beating time is shortened for one time, the dosage of ClO2 is saved, and heat and chemical substances can be recycled. The method for making pulp and paper with young poplars solves the problem of environment pollution caused by paper mills and is suitable for large-scale industrial production.
Description
The present invention relates to a kind of method, relate in particular to a kind of new method with children's willow total-bar slurry making in age with the willow pulping and paper-making.
Traditional wood pulp papermaking is all adopted and adult timber.Slurrying after the need peeling, otherwise will influence the quality of paper, and the peeling process had both bothered contaminated environment, and the existing forest reserves of China reduce gradually, the adult wood raw material is in short supply, and domestic demand to wood pulp paper is in continuous growth, and it is more and more outstanding that imbalance between supply and demand seems, it is wide that this just forces us must seek a kind of raw material sources, and the paper that processes can satisfy the requirement of the cultural paper that is used to manufacture paper with pulp.
The objective of the invention is to overcome the existing wood pulp papermaking shortage of raw materials contradiction of contaminated environment again, a kind of novel raw material are provided, and need not peeling, but full bar new method of slurrying all.
The object of the present invention is achieved like this: it is to adopt the full bar of children willow in age to carry out slurrying without peeling.
The suitable KP+AQ method conditions of cooking of described children willow in age full bar belt leather material is: alkali charge 15%-30%, sulphidity are 20%-30%, AQ consumption 0.02%-0.04%, and liquor ratio is: 1: 4.
The temperature conditions that the full bar belt leather of described children willow in age material adopts the KP+AQ method to steam is: 155 ℃-175 ℃ of maximum temperatures, and the heating-up time is 60-70 minute, temperature retention time is 90-180 minute.
The present invention compares with conventional art, and having full bar papermaking can pull an oar without peeling, and bleachability is good, and environmental pollution is little in the production, reaches discharging standards, and paper strength is big, whiteness good, can satisfy the requirement of the cultural paper of manufacturing paper with pulp.
Below the present invention is described in further detail: the present invention adopts the full bar of children willow in age to pull an oar without peeling, and making beating only needs 30 minutes to 45 ° of SR, and bleachability can good (CLO
2Consumption be 1.0%, the conventional 1.2%-1.5% that needs).In addition, children's Yangchuan village skin in age is still unaged, can overcome the harmful effect of bark to pulping and paper-making, when adopting KP+AQ method pulping by cooking, is the best to adopt following condition and temperature: alkali charge is with 20%, sulphidity 25%, and AQ consumption 0.03% liquefies and is advisable at 1: 4.Temperature conditions: 165 ℃ of maximum temperatures, heating-up time 60-70 minute, temperature retention time 120 minutes, screened yield 41.0% as a result, and Kappa number 16.2 reaches industry standard BY-A level, can satisfy the requirement of the cultural paper that is used to manufacture paper with pulp, and heat and chemical substance are recyclable, and be free from environmental pollution, is suitable for industrial production.
Claims (1)
