Abstract
The invention discloses the method for a kind of mao bamboon cylinder material drying, select mao bamboon cylinder material length to be 450mm-500mm, cylinder material just moisture content is greater than 50%, whole cylinder material dry run is divided into three phases: the first stage is warm-up phase, time 12h, relative humidity controls 60%, temperature 50 C; Second stage is drying stage, time 13-56h, and relative humidity controls 45%, temperature 50 C, and wherein, in the 13-24h stage, relative humidity controls 45%, temperature 50 C; In the 25h stage, carry out conditioning, relative humidity controls 60%, temperature 50 C; In the 26-56h stage, relative humidity controls 45%, temperature 50 C; When the present invention adopts above technical method dry to mao bamboon cylinder material, do not need bamboo in cylinder material every getting through, diameter can be made to be dried to moisture content at the mao bamboon cylinder material of below 12cm through 80h is about 15%, after drying terminates, and mao bamboon cylinder material does not ftracture appearance.
Description
Technical field
The present invention relates to the method for a kind of mao bamboon cylinder material drying, effectively can improve mao bamboon cylinder material dry mass.
Background technology
Along with the growing tension of wildwood wood supply, and people are to the increase of natural material demand, and the efficiency utilization of bamboo wood obtains very large development.Wherein, mao bamboon due to grow fast, output is high, material good, purposes is wide, has become the bamboo kind of China's economy of forestry Maximum Value.But bamboo wood is easy to crack, the feature of easily going mouldy, sternly
Heavily have impact on environment for use and the aesthetic requirements of bamboo wood, constrain bamboo utilization.
Drying improves Material Physics mechanical property, reduces the loss of material degradation, improve stock utilization, ensure the important step of quality of item; Being Appropriate application material, the important technique measure of saving material, is the important procedure in biological material processing.Current China studies more to bamboo fiber board, bamboo carbon, vinegar etc., construction unit mostly generally is bamboo chip, bamboo slights and the forms such as particle, to the rarely seen report of research of cylinder material drying.
Summary of the invention
The object of this invention is to provide a kind of drying means of mao bamboon cylinder material, this kind of method effectively can improve the utilization of bamboo wood.
For realizing above object, the present invention adopts following technical scheme:
A method for mao bamboon cylinder material drying, is characterized in that, select mao bamboon cylinder material length to be 450mm-500mm, cylinder material just moisture content is greater than 50%, and whole cylinder material dry run is divided into three phases:
First stage is warm-up phase, time 12h, and relative humidity controls 60%, temperature 50 C;
Second stage is drying stage, time 13-56h, and relative humidity controls 45%, temperature 50 C, and wherein, in the 13-24h stage, relative humidity controls 45%, temperature 50 C; In the 25h stage, carry out conditioning, relative humidity controls 60%, temperature 50 C; In the 26-56h stage, relative humidity controls 45%, temperature 50 C;
Phase III is the Balance Treatment stage, time 24h, closing temperature and relative humidity, allows sample leave standstill in dry kiln.
Further, select mao bamboon cylinder material length to be 480mm, cylinder material just moisture content is 60%.
When the present invention adopts above technical method dry to mao bamboon cylinder material, do not need bamboo in cylinder material every getting through, diameter can be made to be dried to moisture content at the mao bamboon cylinder material of below 12cm through 80h is about 15%, after drying terminates, and mao bamboon cylinder material does not ftracture appearance.
Detailed description of the invention
A method for mao bamboon cylinder material drying, select mao bamboon cylinder material length to be 450mm-500mm, cylinder material just moisture content is greater than 50%, and whole cylinder material dry run is divided into three phases:
First stage is warm-up phase, time 12h, and relative humidity controls 60%, temperature 50 C;
Second stage is drying stage, time 13-56h, and relative humidity controls 45%, temperature 50 C, and wherein, in the 13-24h stage, relative humidity controls 45%, temperature 50 C; In the 25h stage, carry out conditioning, relative humidity controls 60%, temperature 50 C; In the 26-56h stage, relative humidity controls 45%, temperature 50 C;
Phase III is the Balance Treatment stage, time 24h, closing temperature and relative humidity, allows sample leave standstill in dry kiln.
