Abstract
The invention discloses a bamboo softening/carbonizing modification process. The bamboo softening/carbonizing modification process comprises the steps that 1, bamboo is cut into segments and placed into industrial microwave equipment to be subjected to microwave processing; 2, the bamboo subjected to microwave processing is placed into mildewproof mothproof liquid prepared in advance to be soaked for 3-5 min and taken out to be drained; and 3, the bamboo processed in the step 2 is dried for 20-30 hours at the temperature of 35 DEG C-45 DEG C, then heated to 60 DEG C-70 DEG C and dried for 50-60 hours and finally cooled to 50 DEG C-60 DEG C and subjected to heat preservation for 5-10 hours. The bamboo softening/carbonizing modification process has the beneficial effects that the specific microwave processing process is adopted to replace a traditional high temperature steaming-boiling process to process the bamboo, nutrient substances in bamboo fiber can be removed, and mildew and moth-eaten situations are effectively prevented; in addition, natural plant extracts are adopted to process the bamboo, no poisonous and harmful chemical additive is added, the mildewproof mothproof effect of the bamboo is further improved, and the bamboo is softer and tougher; and the color fixing function is achieved, so that the bamboo is prevented from being deformed and discolored.
Description
Technical field
The present invention relates to bamboo product production technical field, it particularly relates to a kind of bamboo soft/carbonizing and modifying
Technique.
Background technology
Bamboo, has another name called bamboo, formal name used at school Bambusoideae (Bambusaceae or Bamboo), is standing grain basis
One branch of section, is distributed in subtropical zone, has short like grass, has again high such as big tree.Generally by ground
Under the rhizome crawled grow in flakes.Can also be by blossoming and having seeds procreation, its seed is referred to as bamboo rice.For many
Year raw plant.There are some species of bamboo sprout edible.For tall and big, grow rapid grass kind plant, stem
For wooden.It is distributed in the torrid zone, area, subtropical zone to warm temperate zone, East Asia, Southeast Asia and the Indian Ocean and the Pacific Ocean
Being distributed on island and concentrate most, kind is the most most.Our people always likes bamboo, and China is also to grind in the world
Study carefully, cultivate and utilize bamboo country the earliest.Formed in Chinese historical culture development and spirit culture from bamboo
Great function produced by, bamboo and Chinese poems painting and calligraphy and the relation of long standing and well established of gardens construction, with
And bamboo and people's lives closely bound up in be not difficult to find out, China deserve to be called and is described as " the state of bamboo civilization
Degree ".
Bamboo product refer to bamboo be process raw material manufacture product, mostly be article of everyday use, as chopsticks, chopsticks cage,
Chopping block, bed-mat for summer, tea cup mat, curtain etc., the most popular bamboo flooring and bamboo furniture etc., also have
Some value are higher, such as artwares such as bamboo carvings.The advantage of bamboo furniture is: salubrious uniqueness, winter warm up the summer
Cool, resistance to compression, bending strength are good, the feature such as environmental protection.Shortcoming is: easily damage by worms mouldy, just holds after damaging by worms
Easily be broken, use in the north may ftracture, deformation etc..In order to overcome bamboo product easily to damage by worms, mouldy and open
The problems such as fission shape, conventional processing method is by bamboo high temperature steaming, and uses the chemicals such as hydrogen peroxide
Bleaching, carbonization.Such method exists to waste time and energy, and cost is high, heavy-polluted defect, and bamboo is anti-
Mould insect resistance is the best.
For the problem in correlation technique, effective solution is the most not yet proposed.
Summary of the invention
It is an object of the invention to provide a kind of bamboo soft/carbonizing and modifying technique, it is to avoid use at chemical agent
Reason bamboo, processes the time short, and production cost is low, relatively environmental protection, and modified bamboo anti-mould and anti-moth is good,
It is difficult to craze and transfiguration, effectively overcomes currently available technology above shortcomings.
It is an object of the invention to be achieved through the following technical solutions:
A kind of bamboo is soft/carbonizing and modifying technique, comprise the following steps:
Step 1: by preprepared bamboo cutting, the bamboo of cutting is put into the work pre-set
Industry microwave equipment carries out microwave treatment；
Step 2: the bamboo after microwave treatment is put in preprepared anti-mould and anti-moth liquid and soak
3-5min, taking-up drains；
Step 3: the bamboo after step 2 being processed dries 20-30 hour at 35-45 DEG C, then heats
Dry 50-60 hour to 60-70 DEG C, be finally cooled to 50-60 DEG C and be incubated 5-10 hour.
Further, the concrete technology of described step 1 microwave treatment includes:
5-8min is heated, then with the high power section heating of microwave power with the low power period of microwave power
3-5min, then with the middle power section heating 4-7min of microwave power.
Preferably, the microwave power of described low power period is 10-20KW, the microwave of described middle power section
Power is 30-50KW, and the microwave power of described high power section is 80-100KW.
Further, the anti-mould and anti-moth liquid in described step 2 includes leaf of Cortex cinnamomi camphorae extract.
Further, the preparation method of described leaf of Cortex cinnamomi camphorae extract includes:
The leaf of Cortex cinnamomi camphorae gathered in advance is dried to moisture content below 10%, carries out pulverization process, and
Solid-liquid ratio by 1g: 10-15ml adds dehydrated alcohol and mixes, and extracts at 40-50 DEG C
30-40min, and carry out filtration treatment, filtering residue is pressed the solid-liquid ratio of 1g: 8-12ml and is added dehydrated alcohol,
At 40-50 DEG C, extract 40-60min, and again carry out filtration treatment, the filtrate obtained is closed
And, obtain leaf of Cortex cinnamomi camphorae extract.
The invention have the benefit that and avoid using Chemical treatment bamboo, processing the time short, production cost is low,
Relatively environmental protection, modified bamboo anti-mould and anti-moth is good, the most soft more tough, is difficult to craze and transfiguration, and concrete passes through
Use specific microwave processes to replace traditional high temperature steaming to process bamboo, bamboo can be removed fine
Nutrient substance in dimension, destroys moth and the conditions of existence of antibacterial completely, prevents from going mouldy and damaging by worms, microwave treatment
After complete, use natural plant extract to process bamboo, without any poisonous and harmful chemical addition agent, enter
One step strengthens anti-mould and anti-moth effect of bamboo, can prevent bamboo surface discolouration simultaneously, strengthens glossiness.Finally
Use specific stoving process so that bamboo is the most soft more tough, has tint retention, prevent bamboo deformation, become
Color.
