Description
Technical field
The invention belongs to dregs of a decoction resource regeneration technical fields, and in particular, to a kind of prescriptions worth thousand gold dregs of a decoction resource regeneration
Utilize the sanitary paper and its method of preparation.
Background technique
Dregs of a decoction resource regeneration is the important proposition of the field of Chinese medicines.Chinese medicine slag is both medical processing enterprise's production Chinese herbal medicine
The discarded object of power boiler discharge generated in the process, while being also the distinctive plant fiber resource of China, it is the weight of pulp and paper industry
Want raw material.The Chinese medicine slag residue that be Chinese medicine remaining after water or organic solvent extraction, ingredient be mainly cellulose,
Hemicellulose and lignin are limited since Chinese medicine is generally herbaceous plant by chemical pulping process and equipment, Chinese medicine slag ingredient
Diversity and complexity and Chinese medicine slag institute fibre-bearing is short and small, influence of the heteroproteose cell mostly with pigment weight so that using Chinese medicine slag into
Row chemical pulping is by a degree of obstruction.
The Organosolv Pulping to grow up in recent years can provide better delignification method, the wood of degradation
There are more response function groups in element, hemicellulose, and easier can recycle, purify from solvent medium.?
Under certain condition, organic solvent can be with the lignin in degrading plant raw material, so that it is efficient to reach lignin, cellulose, hemicellulose
Isolated purpose, and organic solvent can be recovered by distillation, the basic non-wastewater discharge of whole process, be to realize pollution-free green
The effective technical way of environmentally friendly papermaking.
Wherein, ethanol pulping is pulping process the most typical in organic solvent pulping, including self-catalysis, base catalysis
