Embodiment 1

[0014] First make glue, this glue is urea-formaldehyde resin, its raw material comprises formaldehyde 1000 kilograms, urea 500 kilograms, ammoniacal liquor 50 kilograms.

[0015] a. Put 1000 kg of formaldehyde into the reaction pot, adjust the pH value to 8.0-8.2, and add 313 kg of urea;

[0016] b. Heat the material in the reaction pot until the temperature reaches 90°C ± 2°C and keep it warm for 30 minutes. The temperature in the pot should be controlled at 90°C when the reaction is carried out;

[0017] c. Adjust the pH value to 4.8-5.1, and cool down through the jacket of the reaction pot;

[0018] d. When the reaction is 20 minutes, start to measure the muddy point of the materials in the pot. When measuring the muddy point, use a 10 ml measuring cup, put 2 / 3 measuring cup, 25 ℃ water, adjust the pH value to 6.7 when the muddy point is reached, and add 142 kg of urea and 16 kg of ammonia water. At this time, the temperature should be controlled at 88±2°C. Measure the clo...

Embodiment 2

[0029] First make glue, this glue is urea-formaldehyde resin, its raw material comprises formaldehyde 1200 kilograms, urea 700 kilograms, ammoniacal liquor 70 kilograms.

[0030] a. Put 1200 kg of formaldehyde into the reaction pot, adjust the pH value to 8.0-8.2, and add 437 kg of urea;

[0031] b. Heat the material in the reaction pot until the temperature reaches 90°C ± 2°C and keep it warm for 30 minutes. The temperature in the pot should be controlled at 90°C when the reaction is carried out;

[0032] c. Adjust the pH value to 4.8-5.1, and cool down through the jacket of the reaction pot;

[0033] d. When the reaction is 20 minutes, start to measure the muddy point of the materials in the pot. When measuring the muddy point, use a 10 ml measuring cup, put 2 / 3 measuring cup, 25 ℃ water, adjust the pH value to 6.7 when the muddy point is reached, and add 200 kg of urea and 23 kg of ammonia water. At this time, the temperature should be controlled at 88±2°C. Measure the mud...

Embodiment 3

[0044] First make glue, this glue is urea-formaldehyde resin, its raw material comprises formaldehyde 1050 kilograms, urea 600 kilograms, ammoniacal liquor 60 kilograms.

[0045] a. Put 1050 kg of formaldehyde into the reaction pot, adjust the pH value to 8.0-8.2, and add 375 kg of urea;

[0046] b. Heat the material in the reaction pot until the temperature reaches 90°C ± 2°C and keep it warm for 30 minutes. The temperature in the pot should be controlled at 90°C when the reaction is carried out;

[0047] c. Adjust the pH value to 4.8-5.1, and cool down through the jacket of the reaction pot;

[0048] d. When the reaction is 20 minutes, start to measure the muddy point of the materials in the pot. When measuring the muddy point, use a 10 ml measuring cup, put 2 / 3 measuring cup, 25 ℃ water, adjust the pH value to 6.7 when the muddy point is reached, and add 171 kg of urea and 20 kg of ammonia water. At this time, the temperature should be controlled at 88±2°C. Measure the mud...

Abstract

A bamboo dust board for furniture or as floor board and decorative board is proportionally prepared from aged bamboo powder, new bamboo powder and the urea-formaldehyde resin prepared from formaldehyde, urea and ammonia water proportionally.

Description

technical field [0001] The invention relates to a manufacturing process of a bamboo chip board. It can be used as a material for furniture, floors, and decorative panels. Background technique [0002] With the reduction of forest area and the scarcity of wood resources, bamboo has broad market prospects as an alternative product. Bamboo is a resource that can be quickly regenerated. Compared with wood, it has higher strength and better wear resistance. Bamboo resources are being widely developed in our country. In the manufacturing process of bamboo products, a large amount of bamboo chips will inevitably be produced. Under the current situation, these bamboo chips are all treated as garbage, which is actually a waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manufacturing process of bamboo chipboard made of waste bamboo chips. . [0004] The manufacture technology of bamboo chip board o...
