Description
Technical field
The invention belongs to treating of wood field, be specifically related to the method for anticorrosion treatment of a kind of Lignum paulowniae.
Background technology
Phoenix tree, the blue or green paulownia of another name, paulownia fiber crops, also genus fallen leaves megaphanerophyte, up to 15 meters；Trunk is straight and upright, and bark is green, smooth.Originating in China, there is cultivation north and south each province, also views and admires tree for common shade tree and Garden virescence.Phoenix tree is to cultivate the ornamental trees in flower garden.Timber is light and soft, for system wood casket and the good timber of musical instrument.Seed fries edible or oil expression, and oil is non-drying oil.Root bark, stem, leaf, flower, fruit and seed are the most pharmaceutically acceptable, control diarrhoea, hernia, early whitening of beard and hair, have effect of heat-clearing and toxic substances removing.The fiber of bark is pure white, may be used to papermaking and sennit etc..Wood flake can leach mucus, claims wood shavings, hair care.Lignum paulowniae is a kind of important furniture and artware raw material, but it easily corrodes, and affects product property.
Summary of the invention
In order to solve the problems referred to above, the invention provides the method for anticorrosion treatment of a kind of Lignum paulowniae.
The present invention is achieved through the following technical solutions:
The method for anticorrosion treatment of a kind of Lignum paulowniae, comprises the steps:
(1) bacterium solution processes: Lignum paulowniae is put into immersion treatment 2 ~ 3h in the bacterium solution prepared, and period keeps the temperature of bacterium solution to be 30 ~ 32 DEG C；Living bacteria count in described bacterium solution is 2 × 108 ~ 4×108CFU/ml；Utilize mould bacterium solution that Lignum paulowniae is carried out pretreatment, trickle crackle can be formed on the shallow top layer of Lignum paulowniae, the nutritional labeling removed in the plant cell of shallow top layer can be consumed again, the tannins in Lignum paulowniae, flavonoid, aldehydes matter, follow-up process operation can also be decomposed simultaneously；
(2) immersion treatment: the Lignum paulowniae after step (1) being processed puts into immersion treatment 1h in the acetum that mass fraction is 2%, place into immersion treatment 1h in the saleratus solution that mass fraction is 1.5% after taking-up, put it into immersion treatment 30min in the potassium permanganate solution that mass fraction is 2.5% the most again；Can suppress the activity of enzyme in Lignum paulowniae with after acetic acid and saleratus solution immersion treatment, the mycete etc. of above-mentioned steps residual can be inactivated by potassium permanganate solution；
(3) dried: the Lignum paulowniae after processing step (2) with deionized water is rinsed processing, then puts it into that to be dried under conditions of temperature is 45 ~ 50 DEG C to water content be 13 ~ 17% standby；
(4) transformation processes: the Lignum paulowniae after step (3) being processed is put in vapor tight tank, the initial pressure controlled in vapor tight tank is 0.03 ~ 0.05MPa, then in vapor tight tank, inject antiseptic wash, and boost with the speed of 0.1 ~ 0.12MPa/min, until the pressure in vapor tight tank is 0.63 ~ 0.65MPa, after pressurize 8 ~ 10min, then carry out pressure release with the speed of 0.15 ~ 0.18MPa/min, until the pressure in vapor tight tank is identical with outside atmospheric pressure, then Lignum paulowniae is taken out standby；Described antiseptic wash is formed by the material mix homogeneously of following weight portion: 1 ~ 2 part of p-nitrophenyl sulfonic acid, 3 ~ 5 parts of sodium chloride, 1 ~ 2 part of Borax, 3 ~ 6 parts of phosphoric acid hydrogen amine, 4 ~ 5 parts of sodium carboxymethyl cellulose, 2 ~ 3 parts of glyceryl monostearates, 80 ~ 100 parts of water；
(5) guarantee the quality process: after the Lignum paulowniae after processing step (4) with deionized water is rinsed processing, then put it in temperature control box, controlling initial temperature is 35 DEG C, then heat up with the speed of 0.5 DEG C/min, during to 65 DEG C, then lower the temperature with the speed of 0.5 DEG C/min, to 35 DEG C, this is a circulation, and total is taken out standby after circulating 3 times continuously, and period the most once sprays water every 15min and processes operation；
(6) redrying processes: the Lignum paulowniae after step (5) is processed put into temperature be 50 ~ 52 DEG C, relative humidity be to be dried in the environment of 18 ~ 20%, the water content to Lignum paulowniae is not more than 15%.
Further, the viable bacteria described in step (1) is trichoderma and penicillium citrinum.
Further, described in step (4), in vapor tight tank, inject antiseptic wash, be finally as the criterion so that Lignum paulowniae can be totally submerged.
Further, when the water spray described in step (5) processes, the amount every time sprayed is 0.3 ~ 0.4kg/m2 。
There is advantages that the transformation that the inventive method uses processes operation, in well penetrating into inside Lignum paulowniae by antiseptic wash, being filled in the plant cell on shallow top layer, further reduce the easy complexion changed in Lignum paulowniae, cause corruption composition；When guaranteeing the quality process, the repeatedly temperature cycling operation carried out, water balance and the homogenizing of organizational structure of each position in plank can be promoted, be obviously improved its moistureproof, anticorrosion and crack resistence performance.Under the comprehensive function of each step of the present invention, the without putrefaction in 10 years under the conditions of conventional use of the Lignum paulowniae after process, the most mouldy, and there is preferable surface strength.
