Embodiment Construction

[0064] The present invention will be further described below in combination with preferred embodiments.

[0065] A method for manufacturing a clustered bamboo integrated profile, comprising the following steps:

[0066] Firstly, the raw bamboo of clustered bamboo is sawn to a fixed length, split into strips, planed and laminated to obtain clustered bamboo shreds, and then the integrated profile is prepared according to the following steps:

[0067] S1, immerse the planed and yellowed clustered bamboo shreds in water for high-temperature cooking, the water used for cooking contains 5% to 10% hydrogen peroxide and 0.5% to 1% sodium hydroxide by mass, and the cooking temperature is 100℃~120℃, the best temperature is 110℃, and the cooking time is not less than 4 hours.

[0068] S2. Put the wet bamboo shreds cooked at high temperature in step S1 into a carbonization furnace for carbonization. The carbonization temperature is 130° C. to 150° C., the carbonization time is 4-6 hours,...

Abstract

The invention discloses a sympodial bamboo integration profile manufacturing method. The method is characterized by including the following steps: S1, soaking bamboo filaments of sympodial bamboo which are subjected to green planing and yellow removing in water for high-temperature stewing at temperature of 100-120 DEG C for at leat four hours, wherein the water contains, by mass, 5-10% of hydrogen peroxide and 0.5-1% of sodium hydroxide; S2, disposing wet bamboo filaments in a carbonization furnace for carbonizing at temperature of 130-15o DEG C and at pressure of 3-4 MPa for 4-6 hours; S3, drying for the first time, dipping in glue, and drying for the second time after glue dipping; S4, performing high-pressure forming at pressure of being not less than 1.2 t/cm2; S5, performing thermosetting for more than 10 hours at temperature of 80-150 DEG C under the condition that the pressure of being not less than 1.2 t/cm2 is maintained. By the sympodial bamboo integration profile manufacturing method, sympodial bamboo integration profiles meeting structural profile requirements can be manufactured.

Description

technical field [0001] The invention relates to a bamboo forming process, in particular to a method for manufacturing a clustered bamboo integrated profile. Background technique [0002] With the progress of human beings and the rapid development of society, people have higher and higher requirements for housing and living conditions, and more and more sophisticated living supplies. Especially the rapid development of various high-tech products for daily life in the world today has promoted the diversification of human social life. Rapidly improved people's material civilization and living standards. Therefore, people's demand for wood is increasing. In particular, developing countries import large quantities of timber in order to meet domestic demand, while less developed countries conduct disorderly logging in order to survive and export a large amount of timber, causing serious damage to global forest resources. Some timber species have become extinct. Extensive loggi...
