Embodiment 1

[0033] Embodiment 1, gluing process:

[0034] The first step is to cut off the cut bamboo according to the demand length of the restructured bamboo market. At present, more than 90% of the length of the restructured bamboo strips on the market is about 1.90 meters; the second step is to give the cut bamboo to it with a collider Cut open, according to the diameter of the bamboo, cut into several bamboo slices; the third step, remove the green slices, yellow slices, and bamboo knots from the bamboo slices. The green bamboo slices can be used for other products, such as bamboo mats, bamboo curtains, bamboo handicrafts, etc. ; The fourth step is to divide the bamboo slices into 1-6mm thick bamboo strips through the bamboo breaking equipment by means of one broken two, two divided four, and four divided eight; the fifth step is to carbonize the broken bamboo strips, according to Customers require carbonization to light, medium and dark colors, such as the production of natural colo...

Embodiment 2

[0035] Embodiment 2, glue spraying process:

[0036] The seventh step of the above gluing process is replaced by the following content, and the rest of the technical solutions are the same as the gluing process of Example 1.

[0037] The seventh step is the special glue spraying machine, which is composed of conveyor system, air compressor, glue tank, nozzle head and so on. The operator arranges the bamboo wood flatly, each piece cannot be overlapped, and there is a pressure wheel on the bamboo wood to press the bamboo wood to avoid rolling after spraying glue. After being transported to the sealed cabin, the upper and lower sets of nozzles use air to bring the glue into the mist form to balance Spray on the upper and lower sides of bamboo wood, the amount of glue sprayed is between 6% and 12%, the amount of glue applied can be adjusted according to the use of bamboo wood, and the surroundings are closed to prevent the glue from atomizing and leaking after spraying glue. After...

Abstract

The invention discloses a novel production process for reconstituted bamboo and reconstituted wood. According to the process, coating glue and spraying glue which are free of gum dipping and drying are adopted, the gluing amount can be reduced by at least 50%, each wooden veneer and each wooden sheet can be coated and sprayed with original glue without being dried or aired, and production working procedures are reduced. The reconstituted bamboo manufactured through the process can be used for floor decoration materials, floors, reconstituted bamboo furniture and outdoor floor materials and does not contain broken bamboo shreds or building formworks or carriage boards or container bottom boards formed by pressing bamboo chips and bamboo strips, and the density of the manufactured reconstituted wood which is put in a mold to be cold-pressed can reach over 0.9.

Description

technical field [0001] The patent of the invention belongs to the field of reprocessing of bamboo and wood, in particular, it is a new production process of recombined bamboo and recombined wood. Background technique [0002] The forest is the "dispatcher" of nature. It regulates the circulation of air and water in nature, affects climate change, protects the soil from wind and rain, reduces natural disasters, and reduces the harm caused by environmental pollution to people. However, due to the development of society and the continuous improvement of people's living standards, the demand for timber has increased year by year, and excessive logging has caused the global forest to disappear at a rate of 38 hectares per minute, which is equivalent to disappearing a Daxing'an Mountains in 155 days. Therefore, in the existing technology The application of recombined wood and recombined bamboo is very extensive, but although my country has a vast land and abundant resources, the re...
