Description
Technical field
The present invention relates to treating of wood field, particularly relate to a kind of Lignum paulowniae method for anticorrosion treatment.
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 for cultivating in flower garden
Ornamental trees.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
Skin, 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
Pure white, may be used to papermaking and sennit etc..Wood flake can leach mucus, claims wood shavings, hair care.Platane wood is a kind of important furniture
And artware raw material, but it easily corrodes, and affects product property, and, existing Lignum paulowniae aseptic technic, antiseptic effect is not
Good, do not reach the demand of many occasions on market.
Summary of the invention
In order to overcome above-mentioned deficiency, the invention provides a kind of Lignum paulowniae method for anticorrosion treatment.
The present invention is achieved through the following technical solutions:
A kind of Lignum paulowniae method for anticorrosion treatment, comprises the following steps:
(1), by Lignum paulowniae surface clean totally, the aqueous sodium carbonate brushing Lignum paulowniae surface then using mass concentration to be 1.8%,
Natural air drying 20min；
(2), the Lignum paulowniae surface processed through step (1) uniformly being sprayed pressurized clear water, sustained firing 5min, the most again to Lignum paulowniae
Pressurized saline is uniformly sprayed on surface, after sustained firing 10min, and natural air drying；Processed by this, it is possible to significantly improve Lignum paulowniae table
The compactness of face fiber, improves Lignum paulowniae intensity, thus improves the ruggedness of Lignum paulowniae, and can lay well for subsequent treatment
Basis, it is thus possible to improve further the antiseptic effect of Lignum paulowniae；
(3), the elm processed through step (2) is immersed in dissolved with in the water of ozone, uses ultrasonic Treatment simultaneously, continue
30min, then, takes out, and surface air-dries；The cytoactive on Lignum paulowniae surface can be changed, the activity of enzyme in suppression Lignum paulowniae, it is possible to
Make Lignum paulowniae while keeping primary characteristic, there is the anticorrosion of excellence, mildew-resistant, insect protected, antibacterial, anti-current mistake multifunctional modification effect
Really；
(4) Lignum paulowniae processed through step (3) is placed in airtight pressure treatment tank, air is compressed, keep pressure
Reaching 0.1-0.2MPa, in tank, temperature is 58-60 DEG C, and the dwell time is 18min, then to adding anhydrous second in pressure treatment tank
Alcohol, when dehydrated alcohol fills pressure treatment tank, adjusts the temperature to 48-50 DEG C, slowly rises the pressure in tall can, and holding pressure is
0.4-0.5MPa, the retention time is 25-28min；Processed by this, it is possible to strengthen the absorbability of cell, it is possible to improve further
Lignum paulowniae antiseptic property, improves the dimensional stability of timber；
(5) Lignum paulowniae, by step (4) handled well 47 DEG C, under conditions of relative air humidity 35% after 20min, every 10min
It is the potassium citrate solution of 0.12% to mass concentration of Lignum paulowniae surface sprinkling, altogether sprays 4 times, sprayed when for the last time
After, adjust the temperature to 57 DEG C, relative air humidity regulate to 27%, when reach balance after, take out；Again by allowing Lignum paulowniae 47
DEG C, the environment of 32% relative humidity processes 25min, it is possible to strengthen the absorbability of cell, then discontinuity quantitatively sprayed to Lignum paulowniae surface
Spill potassium citrate solution so that drug effect rapidly enters Lignum paulowniae inside and is uniformly distributed, it is possible to quickly fixes drug effect, substantially prolongs
The antiseptic effect of Lignum paulowniae and holding time；
(6) Lignum paulowniae, by step (5) handled well 32 DEG C, process under conditions of relative humidity 10% and reach balance after,.
Further, the saline in described step (2) be mass concentration be the sodium chloride solution of 0.18%.
Further, in described step (2), pressurized clear water is 0.45MPa by pressure pressure, pressurized saline by pressure pressure
For 0.66MPa.
Further, in described step (3), concentration dissolved with the ozone in water of ozone reaches 1-1.5mg/L.
Further, in described step (3) ultrasonic intensity be 18kHz, output be 150W.
Further, described step (5), each fountain height of potassium citrate solution is 0.12kg/m.
The invention has the beneficial effects as follows: the Lignum paulowniae method for anticorrosion treatment that the present invention provides is simple, by each step of the present invention
Process, Lignum paulowniae can be effectively prevented after process and go mouldy, damage by worms or breed bacteria causes the corrosion of Lignum paulowniae, and can be to salt fog
Corrosion has the strongest resistance, extends Lignum paulowniae anticorrosion time, good penetrability greatly, and resistance leachability is strong, substantially prolongs paulownia
The use of wood and holding time, after the present invention processes, Lignum paulowniae wood internal structure is the most stable, compared to not locating in intensity
The Lignum paulowniae of reason improves 12%, and crack resistence performance is greatly improved, and is processed further obtaining great quality for follow-up Lignum paulowniae
Ensure, Lignum paulowniae without putrefaction in 10 years under usual use conditions after process, the most mouldy, can be widely applied to interior/exterior decoration, building
The field such as material, furniture woods.
