Embodiment 1

[0039] A kind of production process step of tea stem particle board is:

[0040] 1) Dry the tea stalks at a drying temperature of 80°C, control the moisture content of the dried tea stalks at 10%, and pulverize them to form broken tea stalks with a particle size of 20-120 meshes;

[0041] 2) Evenly mix the pulverized tea stalk fragments with the adhesive modified urea-formaldehyde resin to form a mixture; the concentration of the adhesive is 65%, and the sizing amount is 12% of the weight of the tea stalk;

[0042] 3) Paving and forming: According to the requirements of the structure design of the tea stalk scrap board, according to the needs of the low density, medium density and high density of the board, the tea stem scrap after sizing can be paved and withdrawn several times to a thickness specification of 200mm Particle slabs of multi-layer structure can also be formed by mechanical or air-laid forming equipment.

[0043] 4) Pre-pressing: the unit pressure of slab pre-pr...

Embodiment 2

[0053] A kind of production process step of tea stem particle board is:

[0054] 1) Dry the tea stalks at a drying temperature of 130°C. The dried tea stalk scraps are controlled at 3%, and crushed to form tea stalk scraps. The particle size of the tea stalk scraps is 20-120 mesh.

[0055] 2) Evenly mix the pulverized tea stalk fragments with the adhesive melamine resin to form a mixture, the concentration of the adhesive is 55%, and the sizing amount is 10% of the weight of the tea stalk;

[0056] 3) Paving and forming: According to the requirements of the structure design of tea stalk scrap slabs, and according to its high-density requirements, the tea stalk scrap after sizing can be evenly spread and withdrawn into a single-layer scrap slab with a thickness of 100mm.

[0057] 4) Pre-pressing: make the slab of tea stalk scraps have a certain degree of compactness, which is convenient for slab transportation and cutting, etc. The unit pressure of slab pre-pressing is 1.0 MPa,...

Embodiment 3

[0067] A kind of production process step of tea stem particle board is:

[0068] 1) Drying the tea stalks at a drying temperature of 100°C, controlling the moisture content of the dried tea stalk scraps to 7%, and pulverizing them to form tea stalk scraps;

[0069] 2) Evenly mix the crushed tea stalk fragments with the adhesive isocyanate resin to form a mixture, the concentration of the adhesive is 45%, and the sizing amount is 5% of the weight of the tea stalk;

[0070] 3) Paving and forming: According to the requirements of the structure design of the tea stalk scrap board, according to the needs of the low density, medium density and high density of the board, the tea stem scrap after sizing can be paved and withdrawn several times to a standard thickness of 150mm Particle slabs of graded structure can also be formed by mechanical or air-laid forming equipment.

[0071] 4) Pre-pressing: Make the slab of tea stalk scraps have a certain degree of compactness, which is conve...

Abstract

The invention relates to a tea stem particle board and a production process thereof. The production process comprises the following steps of: 1) drying tea stems, and crushing the tea stems into tea stem particles; 2) mixing the crushed tea stem particles with an adhesive uniformly to form a mixture; and 3) paving the mixture which is obtained in the step 2) to make the mixture formed, and pressing to form the particle board. By the process, residuals of tea leaves can be utilized efficiently, timber resources are saved effectively, and the particle board which is manufactured by raw materials of the tea stems can be applied to the fields of building renovation, interior decoration, furniture manufacture, transportation and the like.

Description

technical field [0001] The invention specifically relates to a tea stalk particle board and a production process thereof. Background technique [0002] With the development of the economy, in the production process of wood-based panels, people's demand for particle board is increasing day by day, and the enterprises that produce this board are also increasing year by year. However, with the gradual increase of protection of the environment and forest resources in various countries, the wood raw materials used in particle boards are increasingly scarce. [0003] At the same time, with the improvement of people's health awareness, indoor environment awareness and quality of life awareness, the air pollution and health damage caused by volatile organic pollutants in wood-based panels have attracted more and more attention. In my country, following the "soot type" ", "photochemical smog type" pollution, modern people are caught in the third pollution period marked by "indoor air...
