Embodiment 1

[0030] An environment-friendly recovery method of rosewood waste sawdust, specifically comprising the following steps:

[0031] (1) Sieve the discarded rosewood sawdust to 30 meshes, then put it into a stirring mill, and grind it into powder together with a ball milling medium at a temperature of 40° C., and set aside;

[0032] (2) Add NaOH solution to the powder of step (1) and stir evenly, wherein the mass fraction of NaOH is 50%, and the mass ratio of sawdust and NaOH solution is 1:2, put into the pot and stir fry until the sawdust is soft, Then take it out and soak it in warm water for 1 hour, take it out, rinse it, and filter it, and drain the obtained filter residue from the surface water for later use;

[0033] (3) Soak the filter residue treated in step (2) in the soaking solution for 30 minutes, take it out, place it in an oven, dry it, and pulverize it to 30 meshes to obtain sawdust powder, which is set aside;

[0034] Wherein, the soaking liquid is mainly made of t...

Abstract

The invention relates to the technical field of waste wood dust recovery, in particular to an environment-friendly recovery method of rosewood waste wood dust. The environment-friendly recovery methodincludes the steps: 1) crushing and grinding the wood dust; 2) softening the wood dust in alkali liquor and then soaking the wood dust in soaking solution mainly prepared from cape jasmine fruits, redroot gromwell roots, white mustard seeds, dill fruits, sargentg loryvine stems, Mongolian snakegourd fruits, petioled pyrrosia fronds, clove oil, lemon essential oil and ethyl acetate; 3) uniformly mixing the soaked wood dust with Chinese herbal medicine powder, sterilizing mixture to obtain medicinal pillow filling materials and realize environment-friendly recovery of the rosewood waste wood dust. The Chinese herbal medicine powder is mainly prepared from roof iris rhizome, citron daylily roots, violet, wild mint herbs, Chinese tuldoide bamboo culm medium, common selfheal spikes, oriental cattail herbs, resurrection lily rhizome and dahurian angelica roots. The wood dust and the Chinese herbal medicine powder are uniformly mixed to prepare medicinal pillow filling materials, so that a medicinal pillow has flower fragrance, can effectively improve sleep and further has the functions of refreshing, relaxing muscles, stimulating blood circulation, killing bacteria, relieving itching, depressing qi, dissipating blood stasis, stopping bleeding, settling pain, expelling parasites, disinfecting and the like, environment-friendly recovery of the rosewood waste wood dust is realized, anduse values are improved.

Description

technical field [0001] The invention relates to the technical field of recycling waste sawdust, in particular to an environmentally friendly recycling method for waste rosewood sawdust. Background technique [0002] Rosewood, alias: Hainan Dalbergia, Hainan Huanghuali, Huanghuali, the wood color is golden and warm, the heartwood is darker in reddish-brown or dark brown, and has the texture of repeated horns. Because the woodiness of rosewood is extremely stable, it will not deform, crack, or bend regardless of cold or heat, and has a certain degree of toughness, which can be used to make various special-shaped furniture. When rosewood is processed into various special-shaped furniture, sawdust will be produced, and most of the sawdust is directly burned as firewood, which cannot be recycled well, and direct combustion will produce a large amount of carbon monoxide and carbon dioxide, which will pollute the environment. Rosewood sawdust wood powder has a mysterious long-last...
