Description
Technical field
The present invention relates to waste paper recycling fields, and in particular to a method of waste paper pulp-making is squeezed out using screw machine.
Background technique
Waste paper is important renewable resource, and China's paper industry is faced with that there is lack of raw materials, energy shortage and pollution at present
Serious to wait three big main problems, the three big main problems that China's paper industry faces that are recycled as solving of waste paper have provided
Effect approach.Have relevant information introduction, recycles waste paper with using compared with Resources, can saving water 50%, it is energy saving
60% to 70%.If needing 4 m3 to 5 m3 logs to produce 1 ton of chemical pulp using wood raw material, and wastepaper as raw material is utilized, 1.25 tons
Waste paper can produce 1 ton of regenerated paper pulp, be not required to boiling chemicals or reduce chemicals dosage, so as to reduce atmosphere pollution
60% to 70%, bod reduces 40%, and suspended matter reduces 25% in sewage, and recycling waste paper can greatly reduce project throwing
Money reduces operating cost, increases economic efficiency and competitiveness.
