Example Embodiment

[0025] Example 1

[0026] The surface layer shavings are all made of giant fungus, and the core layer shavings are mixed with 40% cotton stalk shavings.

[0027] (1) Cutting and sorting: Cut 800 kg of giant fungus with a grass cutter into a unit length of 5-50 mm, and sort out the impurities and fine leaves in the giant fungus according to the principle of heavy sorting. And carry out drying and sterilization treatment at a temperature of 100-200℃, and control its moisture content between 20-22%.

[0028] (2) Preparation of shavings: The cut giant fungus is fed into the pulverizer for primary powder, then enters the ring grinder for fine grinding, and then is classified into 63% surface layer shavings and 37% core layer shavings through grading and screening. Through secondary drying, the moisture content of the surface layer shavings is 20%, and the moisture content of the core layer shavings is 7.0%.

[0029] (3) Sizing: Sizing the surface shavings and the core layer separately

Abstract

A shaving board manufacturing method includes the following steps of (1) cutting-off and sorting, (2) shaving preparation and classification, (3) shaving mixing, (4) sizing, (5) laying, (6) hot pressing and (7) after-treatment. Shaving boards are manufactured through puelia production. Compared with the prior art, the method has the advantages that (1) raw materials are widely used, puelia can be used independently for board manufacturing and can be mixed with other raw materials for board manufacturing, the application field of the puelia is widened, the problems of the deficiency and uncertainty of non-wood shaving board raw materials are solved, the design scale of a single production is enlarged, and production cost can be reduced; (2) various raw materials are precisely mixed through independent equipment, and the control level of the production line can be improved; (3) puelia shaving guarantees the uniformity and consistency of fibers by means of a smashing and precise grinding two-stage manufacturing mode, and the product yield is increased and subsequent processing performance is improved; (4) by means of distribution of the overall technology and equipment, the problem caused when puelia is applied to industrialization of board manufacturing is solved.

Description

technical field [0001] The invention relates to the expansion of the application field of giant juncao, and further relates to a preparation method of particleboard. 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 timber. At pres...
