Embodiment Construction

[0017] Such as figure 1 As shown, 12mm thick mulberry branch medium density fiberboard is processed and produced by the following steps:

[0018] 1. Handle and store the raw materials of mulberry branches. Since the mulberry branches are all cut during the growing season of mulberry trees from May to June, the content of polypentose, hot water lysate and protein in the branches is high, and the cut mulberry branches are very susceptible to fungal erosion and rot and insects, so the mulberry branches must be dried in the sun after cutting, and then stacked in a sheltered and ventilated place. When the stacking storage period is longer (more than 3 months), it can be sprayed with a mixture of 10% Baidu fungicide and 50% chrysanthemum insecticide or wood anti-mold preservative (such as 3% CH anti-mold) Processing can also adopt the storage method of bagging after peeling or shaving the mulberry strips, so as to ensure the supply of raw materials for the production line througho...

Abstract

A middle-density fibre board is made from mulberry fibres, water-proofing agent and adhesive through cutting mulberry twigs into piece, steaming for softening, adding water-proofing agent, hot grinding, adding adhesive, drying, spreading, pre-pressing, removing edges by sawing and hot pressing. Its advantage is use of cheap mulberry twigs as raw material for low cost.

Description

technical field [0001] The invention relates to a fiberboard and a production method thereof, in particular to a medium density fiberboard and a production method thereof. Background technique [0002] Mulberry is a perennial woody plant. my country has planted mulberry and raised silkworms for more than 5,000 years. Sericulture production has spread all over the country except Qinghai and Tibet, mainly distributed in the Yangtze River, Pearl River, and Yellow River basins. In order to keep the mulberry trees luxuriant for a long period of time, silkworm farmers have to cut and shape the mulberry trees every year. In northern Zhejiang, cutting is usually carried out from May to June. There are more than 7,000 mulberry branches cut from one mu of mulberry orchard, with a total length of more than 10,000 meters and a weight of about 800 kilograms. In the past, mulberry branches as agricultural residues were generally used as fuel, but now with the impr...
