Problems solved by technology

However, what this invention provides is a medium-density bamboo particle board, which has low strength and insufficient internal structure; it cannot meet the requirements for high strength and compactness of the board, such as making laminated floors or carving patterns on the board. Medium density bamboo particle board cannot be used

Embodiment 1

[0018] a, material selection: screen out the bamboo powder with a particle diameter of ≤4 mm, and use the impurity removal device to remove the impurities in the bamboo powder so that the sand content rate is ≤0.2%.

[0019] b, drying: the bamboo powder after the screening is sent into the drier to dry, so that its moisture content is ≤3%. The moisture content of raw materials after drying has a significant impact on the following processes such as sizing and hot pressing, so controlling the moisture content after drying is one of the key processes.

[0020] c. Glue sizing: In production, it is hoped to produce high-density boards with small sizing amount, high strength, good quality and low cost. Therefore, higher requirements are put forward for the sizing process and equipment. How to correctly select bamboo powder The proper ratio of glue and sizing amount, and how to make a small amount of glue evenly distributed on the surface of a large amount of bamboo powder, are all ...

Embodiment 2

[0026] a. Material selection: screen out bamboo powder with particle diameter ≤ 4mm and sand content ≤ 0.2%.

[0027] b. Drying: Put the selected bamboo powder into a drier to dry, so that its moisture content is less than or equal to 3%.

[0028] c, sizing: take 80kg of dried bamboo powder, spray 23kg of melamine-formaldehyde resin into it with a spray gun, and stir evenly. Process parameters are: pressure 0.2~0.35Mpa, viscosity of melamine formaldehyde resin 150~600cp, sizing rate 110~150kg / m 3 .

[0029] d. Pavement: Pave the mixed material directly on the pressure belt and send it to the pre-press.

[0030] e. Pre-pressing: Pre-pressing with a roller-driven continuous pre-pressing machine (multi-roller continuous pre-pressing machine is used in this example), the pre-pressing pressure is controlled at 1.5-1.6Mpa, and the slab compression reaches 1 / 2- 1 / 3.

[0031] f. Hot pressing: heat press the pre-pressed blank board with an oil press, the temperature is controlled a...

Embodiment 3

[0035] a. Material selection: screen out bamboo powder with particle diameter ≤ 4mm and sand content ≤ 0.2%.

[0036] b. Drying: Put the selected bamboo powder into a drier to dry, so that its moisture content is less than or equal to 3%.

[0037] c. Sizing: Take 150kg of dried bamboo powder, spray 25kg of urea-formaldehyde resin into it with a spray gun, and stir evenly. The process parameters are: pressure 0.2-0.35Mpa, viscosity of urea-formaldehyde resin 150-600cp, sizing rate of 110-150kg / m 3 .

[0038] d. Pavement: Pave the mixed material directly on the pressure belt and send it to the pre-press.

[0039] e. Pre-pressing: Pre-pressing with a continuous pre-pressing machine driven by rollers (in this example, a multi-roller continuous pre-pressing machine is used), the pre-pressing pressure is controlled at 1.5-1.6Mpa, and the slab compression is 1 / 2 ~1 / 3.

[0040] f. Hot pressing: heat press the pre-pressed blank board with an oil press, the temperature is controlled...

Abstract

The invention relates to a manufacture process of high-density bamboo chip plates, in particular to a manufacture process of preparing high-density bamboo chip plates by utilizing waste bamboo chips. The made plates have compact edges, fine and even texture structure and inner and outer consentience and can substitute for natural wood as a structural material. For solving the problems, the invention adopts the technical scheme that bamboo chips are used as a main raw material in the process which comprises the working procedures of selecting materials, drying, gluing, paving, preliminarily pressing, thermally pressing and sawing edges. The invention can be used for indoor and outdoor decoration, composite floors, strengthened floors, packing cases and the internal decoration of cars.

Description

technical field [0001] The invention relates to a manufacturing process of a high-density bamboo chip board, which can be applied to indoor and outdoor decoration, compound floor, reinforced floor, packing box and automobile interior decoration. Background technique [0002] Due to the limitation of my country's special geographical location, my country's natural resources, especially forest resources, are still extremely scarce. Compared with wood, bamboo has a shorter growth cycle, higher strength, toughness, wear resistance and water resistance in my country. widely used. In the production process of bamboo products, a large amount of bamboo chips will inevitably be produced. And at present, a large part of bamboo chips is disposed as garbage, which is a waste of resources. [0003] Chinese invention patent ZL200510049609.9 discloses "a kind of bamboo chip board and its manufacturing process", which uses bamboo powder as the main raw material to make boards, which can be...
