Problems solved by technology

At present, the use of non-wood raw materials to produce boards has factors such as large-scale raw material purchases that are not suitable for large-scale purchases, strong seasonality of raw material purchases, and greater environmental factors during the purchase season, resulting in unstable raw material quality and high purchase costs. too large to scale production

Embodiment 1

[0028] All shavings are prepared from giant fungus

[0029] (1) Cutting and sorting: 1,000 kg of giant fungus grass is cut into a unit length of 5-50 mm by a grass cutter, and impurities and small leaves in giant fungus grass are sorted out according to the principle of heavy object sorting. And carry out drying and sterilization treatment at a temperature of 100-200°C, and control its moisture content between 18-20%;

[0030] (2) Preparation of shavings: Put the cut giant fungus grass into the pulverizer for primary powder, then enter the ring grinder for fine grinding, and then classify and sieve into 50% surface shavings and 50% core shavings. Drying, the moisture content of surface shavings is 18.0%, and the moisture content of core shavings is 12.0%;

[0031] (3) Sizing: Sizing the surface shavings and core planing respectively;

[0032] Firstly, the weight of the surface and core layer shavings is measured respectively through the belt weighing conveyor and the electro...

Abstract

The invention discloses a method for preparing a shaving board by using Jujuncao. The method comprises the steps of: (1) cutting and sorting; (2) shaving preparation and classification; (3) shaving mixing; (4) sizing; (5) pavement; (6) hot pressing; and (7) post-treatment step, that is, the shaving board is prepared by the Jujuncao. Compared with the prior art, the method has the following advantages: (1) raw materials are wide in use; the Jujuncao can be singly used for preparing the board, or can be mixed with other raw materials for preparing the board, so that the application field of the Jujuncao is widened, the problems of insufficient raw materials and uncertainty in a non-wood shaving board are solved, the design scale of single production line is widened, and the production cost can be reduced; (2) precise mixing of various raw materials is realized through single equipment; the control level of the production line can be promoted; (3) the Jujuncao shaving adopt a crushing and finish polishing second-level preparation mode to guarantee the fiber uniformity and consistency and to improve the product pass percent and the subsequent machinability; and (5) the problem of applying the Jujuncao to the board manufacturing industrialization is solved through arranging the whole process and equipment.

Description

technical field [0001] The invention relates to the field of application of giant juncao, and more particularly to a method for preparing particle boards by using giant juncao. Background technique [0002] In the past, Jujuncao was mainly used in the production of base materials for edible fungi and animal feed. With the vigorous promotion of Jujuncao and the rapid production characteristics of Jujuncao, the production capacity of Jujuncao can reach more than 20 tons per mu. Its huge production capacity cannot be digested by the demand for edible fungus base material and animal feed, and new digestion and growth points must be found. [0003] At present, China is the world's largest wood-based panel production base and exporting country, and the annual demand for wood far exceeds the production volume of wood. In 2015, the country began to gradually implement the natural forest logging ban, which will inevitably increase the contradiction between supply and demand of timbe...
