Problems solved by technology

The strength and hardness are good, but there are large consumption of raw materials and high processing requirements. Bamboo glue formwork (plywood) has defects such as large gaps, large thickness errors, and low turnover times; bamboo curtain panels (laminated panels) have rough surfaces and often cannot be used. Meet the flatness requirements of the building surface
Particle boards use bamboo chips as the main raw material, and the bamboo chips are mixed with glue and then cold-pressed or hot-press

Embodiment Construction

[0021] As shown in the figure, the bamboo magnesite cement composite board consists of a core layer 1 and a bamboo mat layer 4 and a facing layer 5 that are successively laid on both sides of the core layer from the inside to the outside. The core layer 1 is made of chips and diamond A fusion body 2 formed by mixing magnesium cement with water, and bamboo strips 3 are inserted into the above fusion body 2 . The manufacture method of this bamboo magnesite cement composite board is as follows:

[0022] 1) Raw material preparation: bamboo material, the bamboo material used for making bamboo sticks can be Moso bamboo, also can select other bamboo species for use. Moso bamboo is usually 6 years old (4 degrees) is more suitable, other bamboo species are 4 years old is more suitable.

[0023] 2) The bamboo chips from the bamboo processing plant are passed through a 2cm hole sieve as the bamboo chips raw material.

[0024] 3) Bamboo chips are piled up for aging and dried to a moistu...

Abstract

The invention discloses a bamboo magnesite cement composite board and a manufacturing method thereof. The existing plates are inferior in composite characteristics of intensity, rigidity, density and smoothness and inferior in reuse rate. The chip material and the magnesite cement are taken as the raw materials in the invention. The bamboo strip or bamboo filament is embedded into the magnesite cement as the reinforced material; the chip material is mixed into the cement and taken as the filling material. The magnesite cement is taken as the bonding and reinforcing material to mix the three kinds of materials, which form sandwich layer of the plates. The prefabricated bamboo mat and finish coat are pasted to the upper and lower surfaces and the hot compacting is carried out. The manufacturing method of the invention reduces raw material consumption of bamboo and improves complex utilization rate of recourses. The plates have the advantages of high strength, high hardness, high smoothness, middle density, etc. The product made by the manufacturing method can be broadly used in templet, wrapping plate, partition plate, carriage plate, etc.

Description

technical field [0001] The invention relates to the field of artificial boards, in particular to a bamboo magnesite cement composite board and a manufacturing method thereof. Background technique [0002] Bamboo has the advantages of high strength, high hardness, rich resources, and can replace wood. Bamboo waste and bamboo chips have the characteristics of good filling, uniform expansion, sound insulation, and heat insulation. Therefore, the two are widely used in the panel industry. At present, the wood-based panels produced by bamboo and bamboo chips are divided into plywood, laminated board and particle board according to their structure and processing technology. The first two boards use bamboo as the main raw material. After splitting into pieces, they are glued and hot-pressed into boards. The strength and hardness are good, but there are large consumption of raw materials and high processing requirements. Bamboo glue formwork (plywood) has defects such as large gap...
