Problems solved by technology

[0007] However, the application of traditional Chinese medicine dregs as a sizing agent still cannot process a large amount of various traditional Chinese medicine dregs in actual production, and the pre-treatment time is relatively long. It is necessary to study better and faster processing methods to truly realize the efficient treatment of all traditional Chinese medicine dregs. Turning waste into treasure

Embodiment 1-8

[0032] Raw materials: 20 tons of mixed dregs of Ganoderma lucidum, yam and Atractylodes macrocephala provided by a Chinese medicine company, with a moisture content of about 80%; the weight ratio of mixed dregs of ganoderma, yam and Atractylodes macrocephala is 60:30:10.

[0033] Proportion: 8% crushed medicinal residue + 62% coniferous wood pulp + 30% hardwood pulp

[0034] 16% broken medicinal residues + 54% coniferous wood pulp + 30% hardwood pulp

[0035] 24% broken medicinal residues + 56% coniferous wood pulp + 20% hardwood pulp

[0036] 32% broken medicinal residues + 48% coniferous wood pulp + 20% hardwood pulp

[0037] 1) Pretreatment of raw materials of traditional Chinese medicine dregs: dry the mixed dregs of Ganoderma lucidum, Chinese yam and Atractylodes Rhizoma Atractylodes Rhizome provided by the Chinese medicine company for the first time, and after drying for the first time, the water content of the dregs of the dregs is ≤50%, crush once to make the particle...

Abstract

The invention discloses medicine residue envelope paper. The gram weight is 80 to 200gsm; a main fiber raw material is prepared from traditional Chinese medicine residue slurry, softwood pulp and hardwood pulp with the grain diameter being less than or equal to 3mm and the fiber length less than or equal to 10mm, wherein the weight content of the traditional Chinese medicine residue slurry is 8 percent to 35 percent, the weight content of the softwood pulp is 45 percent to 65 percent and the weight content of the hardwood pulp is 0 to 30 percent. According to the medicine residue envelope paper disclosed by the invention, traditional Chinese medicine residues are used as paper pulp raw materials and are recycled; a treatment step of the traditional Chinese medicine residues is a normal plant fiber raw material pulping process and additional special equipment and treatment technology are not needed; wastes are directly changed into valuable things and resources and cost are saved, so that the treatment difficulty of the medicine residues of a traditional Chinese medicine factory is radically solved. An actual papermaking experiment shows that the envelope paper prepared by doping common wood pulp into the slurry prepared from the traditional Chinese medicine residues meets product quality standards.

Description

technical field [0001] The invention belongs to the technical field of envelope paper and its preparation method. Background technique [0002] At present, the common envelope paper on the market is generally produced by 80g-150g offset paper and kraft paper (natural color kraft paper, white kraft paper). According to different functions, there are also art paper, coated paper and so on. Because envelope paper needs to be printed and formed for packaging, it is required that the paper must have high tensile strength and tear resistance to avoid paper breakage and cracking, and at the same time have good printing performance. [0003] Traditional Chinese medicine dregs are clearly classified as non-hazardous waste in garbage disposal. As long as no secondary pollution is generated, the Environmental Protection Bureau does not impose strict disposal regulations. The existing treatment methods for medicinal dregs mainly include landfill, composting, and incineration. Although ...
