Abstract

The invention relates to an agent for recycling straws by using a biologically cold fermentation method, belonging to the field of recycling and utilization of crop straws. The recycling agent comprises the following components in parts by weight: 2-8 parts of straw rapid corrosion agent, 2-8 parts of sodium dodecyl sulfate, 15-25 parts of dispersed anthraquinone, 60-80 parts of quick lime and 5 parts of fumed silica. The invention also relates to a process for producing plant fibers by using the straws with the biologically cold fermentation method; and the process comprises the following steps of: crushing the straws until the water content reaches 20-50 wt%; adding 40-60% by weight of the agent for recycling the straws by using the biologically cold fermentation method and mixing the mixture uniformly; fermenting and swelling the mixture at a temperature of 20-30 DEG C for 1-3 days to obtain a fermented material; rubbing, devillicating, fibrillating and pulping the fermented material to obtain plant fiber slurry with the beating degree of 37-47 DEG SR (Schopper Riegler). According to the recycling agent and the process provided by the invention, the plant fibers are recycled from the straws by utilizing the biologically cold fermentation method without stewing, so that no waste liquid is discharged in the whole process, the cost is low, the effect is quick, the yield of the prepared slurry is greatly improved, the fibrousness is high, the paper performance is excellent, and the production requirements on various paper products can be met.

Description

technical field [0001] The invention relates to the field of crop straw recycling and utilization, in particular to a biological cold fermentation straw recovery agent, and also relates to a process for producing plant fiber from biological cold fermentation straw. Background technique [0002] As a big straw-producing country, our country is short of arable land and fresh water resources. Crop straws, especially corn straws, cotton straws, wheat straws, etc. are extremely precious. A great waste of resources. Straw contains a lot of fiber and can be used to make paper. [0003] With the development of society, the use of paper products is also increasing rapidly, so the paper industry needs a lot of fiber materials, but the long growth cycle of wood greatly restricts the development of the paper industry, so the fiber is recovered from straw with a short growth cycle The need to exploit is becoming more and more urgent. [0004] However, in the existing technology, the...
