Embodiment 1

[0024] Example 1 Preparation of pure industrial hemp stalk particleboard

[0025] The industrial hemp stalk waste is used as the raw material for the board. It has been determined that the moisture content of the industrial hemp stalk raw material is 15-18%, and the raw material is humidified to control its moisture content to 40%. Use a chipper to make raw materials into fragments with a length of 5-10mm, and then use a double-drum planer to further crush the raw materials to obtain shavings with a length of 3-8mm, a width of 2-4mm, and a thickness of 2-4mm, and use A vibrating sieve removes oversized shavings. Use a single-channel dryer to dry the industrial hemp stalk shavings at 140°C until the moisture content is 3-5%. Apply a urea-formaldehyde resin adhesive to the dried industrial hemp shavings by using a spray glue sprayer, the solid content of the adhesive is 60-65%, and the sizing amount is 8% of the absolute dry weight of the industrial hemp shavings, and at the s...

Embodiment 2

[0027] Repeat Example 1, with the following differences: 10% shaving sizing amount, and the test results are shown in Table 1.

Embodiment 3

[0029] Repeat Example 1, with the following differences: 12% shaving sizing amount, and the test results are shown in Table 1.

Abstract

The invention discloses a high-intensity shaving board and a manufacturing method thereof. The manufacturing method comprises the following steps of: smashing industrial hemp rods into wood shavings; adding 2 to 14 percent of adhesive; and performing hot pressing to obtain the shaving board. A hemp rod/wood composite shaving board can be prepared by further blending common wood shavings. In the invention, the shaving board is manufactured by the industrial hemp rods which have the characteristics of high intensity, a large number of holes and low density for the first time; and compared with a similar wood shaving board product, the shaving board product has the characteristics of low density, high intensity and high load bearing property. By the implementation of the technology, wood resources can be obviously saved, an ecological environment is protected, wastes are made profitable, and a new path is provided for the application of industrial hemp; and further development of an industrial hemp industry is facilitated, and good social and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel processing, and in particular relates to a high-strength particleboard prepared by using industrial hemp stalks. At the same time, the invention also relates to a manufacturing method of the high-strength particle board. Background technique [0002] Cannabis is a woody herbaceous plant belonging to the phylum Angiosperms, Magnolia, Hamamelis, Urtica, Cannabis, Cannabis genus, scientific name Cannabis sativa L. , commonly known as hemp, hemp, cold hemp, thread hemp, flower hemp, etc. There are about 150 varieties. The "United Nations Convention against Illicit Trafficking in Narcotic Drugs and Psychotropic Substances" promulgated in 1988 clearly stipulates that cannabis plants containing tetrahydrocannabinol (THC) < 0.3% no longer have the value of extracting THC toxic components, and there is no direct smoking as drugs. Value, this kind of hemp variety specially designed for industr...
