Abstract
Provided is an insect preventing treatment method for wood. The method comprises the following steps that 1, an insect-resist agent is diluted in water according to the volume ratio of 1:5, an insect prevention solvent is weighed out according to the ratio of the diluted insect prevention solvent to the loading size of the wood of 1:40-60, and the insect prevention solvent is poured into a water tank of an atomized water spraying device; 2, when the wood is dried till the moisture content is lower than 18% and a wood balancing stage is carried out, air inlet and exhaust windows of a drying kiln are closed, and the atomized insect prevention solvent is sprayed into the drying kiln; 3, the atomized insect prevention solvent absorbs heat in the drying kiln and is turned into steam, and the insect prevention solvent permeates into the wood along with the steam; 4, after all the insect prevention solvent in the water tank of the atomized water spraying device is sprayed, the air inlet and exhaust windows of the drying kiln are continuously closed for 12-30 hours; and 5, treatment is finished. The method has the characteristics of being easy to operate, short in time, low in cost and the like, and the technical problems that permeation of an insect-resist agent is hard, and the insect-resist agent is likely to run off are solved.
Description
Technical field
The invention belongs to timber processing and manufacture field, be specifically related to a kind of wood preservation from decay processing method.
Background technology
The macromolecular material that timber is made up of cellulose, hemicellulose and lignin, containing nutriment and the moisture such as soluble sugar divides, starch in it, is the natural place that insect lays eggs and breeds.Usually, the greenwood of just felling is by reasonably dry, and moist wood insect can obtain effectively preventing.But timber product is still subject to grave danger of bole insect in its life cycle.
Wood furniture, floor and timber are the important household articles of people, in use easily cause the erosion of wood borers, and especially in the season of warm moist, this brings huge loss to consumers in general and manufacturing enterprise.Research in the past shows, selects suitable medicament to carry out insect-prevention treatment to timber and effectively can contain the infringement of insect to timber.At present, the method for wood preservation from decay process mainly contains infusion process, diffusion method, hot and cold bath method and fumigating system, and wherein infusion process is most widely used, and it refers to and is directly immersed in insect protected solvent by timber, and insect-proof agent penetrates into wood internal.The advantage of this method is that timber energy entirety absorbs mildew-resistant solvent rapidly, but follow-up also need is carried out dry process and will cause the loss of a part of medicament, and to environment.Chinese patent literature CN104859012A discloses " a kind of wood preservation from decay agent and utilize its process timber method ", airtight impregnation process tank put into by timber by it, be evacuated to-0.08MPa ~-0.1MPa, keep 30 ~ 60min, insect-proof agent is injected impregnation process tank, make the complete submergence timber of solution, remove vacuum and be forced into 0.6MPa ~ 0.9MPa, keep 30 ~ 90min.This processing method impregnating autoclave limited volume used, can not realize extensive batch process, and equipment manufacturing cost is higher.After process, timber still needs to carry out follow-up drying, adds cost and time.
Summary of the invention
The present invention will solve the problem of timber insect pest, utilizes the method for dry insect-preventing integration to process timber, and the method has the features such as simple to operate, the used time is few and cost is low, solves insect-proof agent infiltration technical problem that is difficult and that easily run off.
Object of the present invention is achieved by the following technical programs:
A kind of wood preservation from decay processing method, it comprises the steps:
1), insect-proof agent with volumetric ratio 1:5 at dilution with water
, press after dilutioninsect protected solvent and loading timber volume ratio 1:40-60 measure insect protected solvent, are poured in the water tank of atomized water injection apparatus;
2), at the drying of wood to moisture content lower than 18%, when carrying out timber equilibrium stage, close the intake and exhaust window of dry kiln, to dry kiln internal spraying chemoprevention worm solvent;
3), the rear insect protected solvent of atomization absorbs heat and becomes steam, with steam infiltration wood internal in dry kiln;
4), after the insect protected ejection of solvent, in water jet device water tank to be atomized, dry kiln continues not open intake and exhaust window in 12-30 hour;
5), process terminates.
In the improvement project to wood preservation from decay processing method described above, in step 1, described insect protected solvent is water-soluble insect-proof agent, soluble in water, this insect protected solvent and loading timber volume ratio 1:50.
In the improvement project to wood preservation from decay processing method described above, in described step 2, described moisture content is 8 ~ 10%, and at this moment insect protected solvent easily infiltrates wood internal.
In the improvement project to wood preservation from decay processing method described above, in step 4, described insect protected solvent is after atomising device sprays, and dry kiln continues not open intake and exhaust window in 18 ~ 24 hours.
beneficial effect of the present invention is:the inventive method is easy and simple to handle, and cost is low, and insect-proof agent osmotic effect is good, and the insect protected solvent after atomization is evenly distributed at wood surface and inside, and not easily run off, vermins-proof effect obtains Integral lifting; And owing to realizing dry, insect protected integral process in dry kiln, thus decrease place needed for independent insect-prevention treatment, equipment and artificial, there is the advantage that vermins-proof effect is good, production cost is low and production efficiency is high.
