Abstract
The technological process for making pulp by using artificially-cultivated paper mulberry is characterized by that its tappa is undergone the forced raw material preparation p rocess and HAP method can be adopted to prepare tappa pulp, and APMP method can be used to make its trunk into chemimechanical pulp. Said invention adopts normal-pressure, low-temp., low-alkali, high-concentration and short-time pulping process, and can simultaneously implement cooking and bleaching two operations, and can obtain high-whiteness, high-quality and high yield and low-consumption tappa pulp and trunk pulp.
Description
One. the invention belongs to the new technology of paper industry with paper mulberry slurrying.
The paper mulberry slurrying that China is traditional all is to be raw material with wild tapa (without the paper mulberry bar).The feature of raw material of this project: without wild paper mulberry, but with 1 year of the artificial growth living paper mulberry of speed.Traditional production method adopts alkaline process and sulfate process (the auxiliary agent methods of indivedual station-service applicant inventions).With the wild paper mulberry skin prescind, soaked back adds boiling vessel (rotary spherical digester) with alkali lye, feed steam and carry out boiling.(production process comprises; Heat up, put little vapour, heat up, be incubated, amplify vapour, blowing again).At high temperature utilize the effect of alkali, the lignin in the cladding and other foreign material are deviate from, make paper pulp.Because of having one deck casting skin shell, the bark top layer is difficult to cook out, so traditional digesting technoloy all is to adopt; The hard boiling technology of high temperature, high alkali number, long-time insulation.Deviate from though the casting skin shell is dissolved, made fiber be subjected to serious destruction, caused the yield of pulping very low (abbreviating " three high one is low " hard boiling technology as).This traditional hard boiling technology material consumption is many, energy consumption is high, production cost is expensive, pollutional load is heavy.For quality and the output that improves pulping, for energy-saving and cost-reducing, the contaminated solution problem.At the deficiency of traditional handicraft, the applicant has finished two-step method slurrying through the research of more than ten years.It is characterized in that: raw material separates skin, bar earlier after preliminary treatment, and removes with the casting skin shell of partly mechanical method with the bark top layer, makes white cladding, removes to make latex with white cladding then.Latex successively experienced four generation pulping process reform, promptly by traditional soda pulping process, change into the auxiliary agent method, again change into the APO method, until the HAP method the 4th generation new process.Realized by the traditional handicraft of " three high is low " transformation to " three low height " advanced technologies.Result's contrast of now the structure leather being starched the reform of four foundries skill is as following table.
The structure leather is starched the process conditions of four generations reforms and contrast table as a result and is become pulp yield magma whiteness for condition with raw material alkali charge cooking pressure (temperature) temperature retention time as a result
The artificial white skin of the wild structure skin 25 of production method % Kg/Cm ℃ of branch % % generation tradition alkaline process～wild structure skin 17 5 (158) 120 42 light three generations APO methods of 32 6.5 (167) 360 20～26 dark two generation auxiliary agent methods 10 0 (90) the 180 75 73 4 artificial white skins 50 (80) 30～50 92 80 of generation HAP method
Two. the present invention considers the enforcement of China's natural forest protection engineering.After the natural forest taboo was cut down, the wild paper mulberry skin will no longer may be supplied in a large number.Must use the artificial growth paper mulberry instead.Walk the combination of woods paper, woods paper is integrated.Walk the road of artificial fast-growing, high-yield woods.Use the paper mulberry system paper pulp of artificial growth.Be second feature of the present invention.This project adopts the new and high technology of forestry, and the annual paper mulberry of high-density planting has been realized the plantation of forestry chemurgy, and paper mulberry has been carried out complete attached comprehensive utilization (patent is declared in plantation of paper mulberry and comprehensive utilization in addition).
Three. paper mulberry bar pulping and paper-making in the past both at home and abroad all is out of use.After the present invention has started the artificial growth paper mulberry, for outlet is sought in the utilization of giving the paper mulberry bar.The present invention has finished the research of paper mulberry bar APMP method machine slurry.Not only widened raw material, and provide a kind of novel, high whiteness, high yield, high-quality, energy-saving and cost-reducing change machine slurry for paper industry for paper industry.With paper mulberry bar work machine slurry is the 3rd feature of the present invention.
Four. pollutional load of the present invention is light, and pulp-making waste-water is faint yellow, PH7.5～8.Can handle together (but handling just qualified discharge) with middle-stage wastewater through general biochemistry and materialization.The 4th feature of the present invention is clearer production technology.
