Description

A kind of carbonization method of high-carbon anti-corrosion bamboo wood
Technical field
The present invention relates to a kind of carbonization method, particularly a kind of carbonization method of high-carbon anti-corrosion bamboo wood.
Background technology
Using the sheet material that bamboo wood is made as Raw material processing because raw material is cheap, be easy to get, low cost, good appearance and intensity is high, performance is good and be widely used in the dalles such as floor, wallboard, furniture or other industry.Particularly Bamboo Growth is fast, aboundresources, and wooden boards can be not only replaced very well, has saved timber resources, and is conducive to the protection of ecological environment, thus is increasingly subject to national to be paid much attention to industry.But, during being higher than timber, thus storage in bamboo wood, processing and the use of bamboo product due to the content of the organic matters such as bamboo wood internal starch, carbohydrate, more it is also easy to produce than timber and goes mouldy, brown stain and damaged by worms, influence the attractive in appearance and service life of bamboo product.So, the sheet material being made as Raw material processing using bamboo wood is had to by the removal of organic matter.Traditional bamboo wood organic matter removal mode is usually to use boiling, processed by the noxious chemicals for being put into anticorrosive mildewproof, so as to reach the purpose for being decomposed the organic matter nutrients such as sugar, the fat in bamboo wood, but, which not only can not complete organics removal, and can store harmful components again in process, such as chlorine, sulphur material are unfavorable for health.
At present, bamboo wood organic matter removal mode is broadly divided into two kinds of high pressure carbonization and high temperature cabonization.Wherein, high pressure carbonization refers to that dried bamboo wood is placed in carbonization tank, by being put into raise steam, bamboo wood is warming up into 125~175 DEG C, then constant temperature certain hour, so as to reach the purpose of organics removal.On the one hand, due to the high pressure carbonization by being put into steam, it is difficult to bamboo wood to be warmed up to the temperature for making its organic matter get rid of completely enough, on the other hand, due to the high pressure carbonization by being put into steam, the control sensitivity to temperature is not very strong.And high temperature cabonization refers to that dried bamboo wood is placed in the carbonizing chamber of normal pressure, bamboo wood is warming up to 100~300 DEG C by conduction oil, changes in process parameters is larger in the method production process, it is due in temperature-rise period, the constant temperature time in each stage is different, and the maximum temperature for heating up is not sought unity of standard, so as to cause the bamboo wood shade after carbonization to differ, easily cause that organic matter removal degree is inadequate or organic matter removal is excessive, so as to bamboo wood hardness can be caused to decline, and then cause that the bamboo panel product produced tends not to meet international standard, the advantage of bamboo wood high temperature cabonization cannot to greatest extent be played.
The content of the invention
The purpose of the present invention is to overcome the above-mentioned not enough of prior art and provide a kind of carbonization method of high-carbon anti-corrosion bamboo wood, it can not only ensure to make the clearance of organic matter in bamboo wood reach maximum by high temperature cabonization under conditions of the flexible sexual satisfaction requirement of bamboo wood, so as to increase substantially the antiseptic property of bamboo wood, the bamboo wood that stacking can also be made highly different obtains uniform carburized, so that bamboo wood color after carbonization is uniform, no color differnece, and it also has the advantages that with short production cycle, simple to operate, safety and environmental protection.
The technical scheme is that:A kind of carbonization method of high-carbon anti-corrosion bamboo wood, comprises the following steps:
1)Fresh bamboo wood removes tabasheer, is made bamboo chip, dries;
2)By dried bamboo chip, neatly tiling is placed on the rack of carbonization kiln, measures the tiling thickness h of now bamboo chip, according to tiling thickness h, setting carbonization benchmark;
3)Heated up stage by stage according to set carbonization benchmark, and temperature to reaching each stage is incubated, until the organic removal rate Q of all bamboo chips in carbonization kiln just reaches maximum when meeting flexibility requirements;
4)After the completion of carbonization, carbonization kiln is lowered the temperature using atomization cooling method, after temperature drops to uniform temperature, go out the kiln that is carbonized, obtain high-carbon anti-corrosion bamboo wood.
Further technical scheme is the present invention:Step 2)In setting carbonization benchmark concretely comprise the following steps:
(1)On the multilayer rack dried bamboo chip uniformly fitly tiled in carbonization kiln kiln car, unify the bamboo chip thickness on every layer of rack, measure the thickness h;
(2)According to thickness h, it is determined that needing to carry out the times N of stage intensification, the maximum temperature T in each stage, the soaking time t of each step temperature;
3rd, the carbonization method of the high-carbon anti-corrosion bamboo wood described in claim 2, it is characterised in that step(2)In as 0 < h≤10mm, N=1, T=180~240 DEG C, t=1~3h;As h > 10mm, the number of times that the stage heats up is more than N > 2, and the number of times that the stage heats up is proportional with h.
Further, step 3)In only when the organic removal rate Q1 of the rack upper surface bamboo wood measured after each holding stage terminates is equal with the organic removal rate Q2 of inner core bamboo wood, just carry out the heat temperature raising of next stage.
Further, step 4)In atomization cooling method be specially:
(1)Atomization tap is opened, the atomization water power air cock of control cabinet is opened, after steam drain displacement diminishes, starts atomized water spraying cooling;
(2)In spray process, blower fan is closed down manually, half an hour changes a wind direction;
(3)When temperature drops to 120~170 DEG C, note observing the temperature data that thermometer is indicated, when 10~50 DEG C of the temperature data reduction for indicating, stop atomized water spraying, during data stabilization to be instructed, then start atomized water spraying;When temperature drops to 105~115 DEG C, crack between a door and its frame is stoppered with rag, entered in kiln with air-prevention;
(4)When temperature is reduced to 90~100 DEG C, exhaust outlet is closed, when continuing a small amount of atomized water spraying and cooling to 80~85 DEG C, blower fan is turned off during pending data stabilization, finally opened and steam sink faucet, to injecting cold water in tank;
(5)Natural cooling is carried out using the cold water in bosh, when being cooled below 75 DEG C, you can open wicket.
Further, temperature data changed no more than 2 DEG C i.e. in stable state in one minute in atomization temperature-fall period.
Further, the step of being atomized temperature-fall period(5)In, when opening wicket, the temperature of inner core bamboo wood is less than 75 DEG C.
Further, step 3)In the previous temperature rise period terminate after and be intended to the organic removal rate of measurement surface bamboo wood and inner core bamboo wood respectively before latter temperature rise period starts.
Further, step 1)After the completion of middle drying, the moisture content of bamboo chip is 13~17%, and bamboo chip is the thread bamboo sheet obtained after rolling.
Further, step 3)It is to carry out at ambient pressure.
