Problems solved by technology

However, compared with wood-based panels, there are some problems in the production technology of crop straw-based panels: the use of traditional methods for material crushing or fiber separation results in low fiber acquisition rate and poor shape, which affects the physical properties of the product; Contains substances that are not conducive to bonding, so it is difficult to obtain satisfactory bonding strength with traditional urea-formaldehyde resin or phenolic resin glue

Embodiment Construction

[0025] Fig. 1 is the flow chart of the present invention utilizes crop stalks and timber to mix and manufacture artificial panel method, as shown in Fig. 1, this method comprises:

[0026] Step 1: The processed wood raw material and at least one processed crop straw are sent to the dry silo for uniform mixing;

[0027] Step 2: After the mixed materials are measured, they are sent to the glue mixer for sizing together;

[0028] Step 3: Send the shavings after sizing to the surface and core layer paving machine, and the paving machine will pave a uniform and flat slab on the backing plate;

[0029] Step 4: The slab is pre-pressed by a continuous pre-pressing machine;

[0030] Step 5: After pre-pressing, it is transported to a multi-layer hot press for hot-pressing to obtain a raw board;

[0031] Step 6: Send the raw board to the cooling machine and stay in the cooling machine for a period of time;

[0032] Step 7: The raw board is sent to the vertical and horizontal cutting a...

Abstract

The present invention discloses the process of making artificial board with the crop stalk and timber. The process includes the following steps: mixing processed timber material and processed crop stalk material in a dry material bin, mixing with glue in a glue mixing machine, spreading in a spreading machine to form board blank, pre-pressurizing in a continuous pre-pressurizing machine, hot pressing in a hot press to form coarse board, cooling in a board cooling machine, and cutting in a margin cutting machine to obtain artificial board. Making artificial board with the crop stalk and timber can save timber and make artificial board with high quality.

Description

technical field [0001] The invention relates to a method for manufacturing an artificial board, in particular to a method for manufacturing an artificial board by mixing crop stalks and wood. Background technique [0002] Wood-based panels are widely used in many fields and gradually expanded due to their good physical properties and easy machining, surface processing and finishing properties. The main raw materials of wood-based panels currently on the market are wood. The use of a single wood-based panel to manufacture products results in huge waste of wood, and a single wood-based panel is easy to deform and split, which affects the use effect and life of the product. With the advancement of science and technology and the improvement of farmers' living standards, straw is no longer used as a daily fuel in rural areas. Exploring an effective way to comprehensively utilize straw to alleviate the problem of scarcity of wood resources that is expanding rapidly has attracted ...
