Embodiment Construction

[0015] (1) the seaside mallow stalks after harvesting the seeds are collected;

[0016] (2) chopping and making coarse material: seashore mallow stalks are pulverized into fragments less than 4cm with a pulverizer as coarse material, so as to further pulverize;

[0017] (3) Screen and dedust the coarse material: further eliminate impurities such as seeds and dust; the stalk fragments after screening are relatively clean, improving the quality of raw materials;

[0018] (4) Coarse material re-crushing: the coarse material cleaned after (3) is further crushed into finer debris;

[0019] (5) Cooking and extracting: Put the seashore mallow coarse material treated in (4) into a cooker or pool, add tap water to submerge it, cover and seal it, and let it boil for 45-60 minutes with steam to soften it , to facilitate the exudation and dissolution of soluble substances and the dissociation of fibers;

[0020] (6) heat grinding: send the seashore mallow scraps softened through (5) int...

Abstract

The present invention belongs to the field of ecological engineering technology, and is especially process of making medium density fiber board with beach mallow stalk. The present invention makes it possible to convert great amount of the biomass of beach mallow into fiber board capable of replacing woody fiber board.

Description

1. Technical field [0001] The invention belongs to the technical field of ecological engineering, and specifically relates to a method for producing medium-density fiberboards by utilizing seashore mallow straw, a non-wood fiber material. 2. Background technology [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, my country's construction, decoration, furniture, packaging and other industries have risen rapidly, and people's consumption of panels has continued to increase. In the past, wood boards or wood fiber boards were mostly used in construction, decoration, furniture and packaging, but my country's per capita forest stock volume is only 0.12m3, which is far lower than the world's per capita forest stock volume of 0.65m3 3 level, while my country's current average annual total wood consumption is 2.5×10 8 m 3 , my country's forests have been severely damaged, the area has shrunk rapidly, and the tim...
