Abstract
The invention relates to a method for pressure impregnating a medical solution for modifying wood, which is a method for mainly aiming at the wood with large humidity, under a certain pressure, impregnating chemical reagent from the end of a log, while replacing tree-juice from the log, and performing chemical modification processing to the wood and improving multi-term performance and value. The method is characterized in that the impregnation pressure is small (the pressure is not over 0.8 MPa), the permeation of the medical solution in the wood is even, the absorption is good, the use amount of the medical solution is small, and the medical solution is applicable for the industrial production, various polymers such as coloring agent, anticorrosive agent, fire retardant, modifier and so on can be impregnated to the humid log, and the log with various size can be impregnated and processed.
Description
Technical field
The present invention relates to a kind of medicated liquid pressuring and injecting method that is used for Wooden modifying, specifically, be a kind of at the bigger timber of humidity, chemical reagent is impregnated in termination from log under certain pressure, timber is carried out the method that chemical modification processing improves its multinomial performance and value, belong to wood processing field.
Background technology
Type in the mode main three of timber pickling at present: open normal pressure impregnates, and the closed high pressure impregnates and vacuum is impregnated, and its corresponding apparatus is normal pressure immersion can, high pressure immersion can and vacuum immersion can.These several classes are impregnated the top layer that equipment and the mode of impregnating can immerse modified solution timber preferably, but owing to be subjected to the inhibitory action of timber internal liquid and air, even under very high pressure or vacuum degree condition, modified solution also is difficult to be immersed in equably in the lumen and cell membrane of timber deep layer, therefore cause and impregnate overlong time, soup is used the most excessive and is produced waste, and soup permeates inhomogeneous in timber.
At present, some patent reports in this respect that CN1490136A has reported as patent, timber is placed high-pressure bottle, be evacuated down to vacuum and be-0.3～-0.85MPa, kept 15～60 minutes, suck resin then, treat to remove vacuum after resin is full of container, slowly be pressurized to 0.1～0.2MPa, kept 6～24 hours, then resin is discharged, being evacuated down to vacuum once more is-0.65MPa to keep 3～15 minutes.Patent CN200984766Y has reported the multi-functional timber pressure impregnation of a kind of automatic control jar, the vacuum port of impregnating autoclave is connected with vacuum valve, vavuum pump etc., the pressurization mouth of impregnating autoclave is connected with check-valves, pressurizing valve, force (forcing) pump, controls by automatic controller and vacuumizes, removes vacuum, pressurization, conversion between the process such as vacuumizes again.Patent CN2521010Y has reported a kind of high pressure impregnating machine that is used for timber, promptly the end at the trough of a upper shed is equipped with fastening baffle plate, the other end is equipped with high-pressure pump, fluid storage tank is equipped with on the top of trough, fluid storage tank presses mouth to link to each other by liquid discharging tube and taper shape, during use timber is put into open slot, opens valve liquid is put into the conical mouth of pressing, open high-pressure pump, under the high pressure effect, liquid is pressed in the timber.
Summary of the invention
The present invention is used for the medicated liquid pressuring and injecting method of Wooden modifying, by main by frame, add the timber pressure impregnating equipment that locking oil cylinder, fluid injection band tooth seal disc, discharge opeing band tooth seal disc, collecting tank, log lifting support, seal disc lowering or hoisting gear and topping-up pump constitute, impregnate chemical reagent being no more than under the 0.8MPa pressure termination, the resin of log is cemented out from log.
Method of the present invention is to utilize the log lifting support to adjust log to the appropriate location, utilizes seal disc lifting handwheel to adjust fluid injection band tooth seal disc and discharge opeing band tooth seal disc and the alignment of log two ends.Utilization adds locking oil cylinder fluid injection band tooth seal disc and discharge opeing band tooth seal disc is snapped in the log two ends.Under the pressure effect of topping-up pump, the fluid injection band tooth seal disc that enters log one end by flexible pipe enters log from the chemical reagent of medical solution pool, and enters the resin collecting pit from the resin that the other end of log is extruded by flexible pipe.
When the other end of log no longer flows out resin, open pneumatic unloader and pressurization conversion valve, the valve closing that will lead to resin collecting pit pipe simultaneously, from the chemical reagent of medical solution pool under the effect of topping-up pump pressure, the discharge opeing band tooth seal disc that enters the log other end by flexible pipe is injected into log, from the chemical reagent backflow medical solution pool of log other end outflow.
The present invention uses trees in growth course, this principle of each position that nutrient in the soil and moisture fiber duct or test-tube baby and the capillary etc. by trees are transported to trees continuously, under the bigger situation of timber humidity, the nutrient of timber and moisture induction system remain intact, the termination thick at log applies certain pressure, chemical reagent is injected, and the resin in the log is cemented out.This characteristics of impregnating mode: impregnate pressure little (pressure is no more than 0.8MPa), the infiltration of soup in timber is even, good absorbing, and speed is fast, and the soup consumption is little.The inventive method can be impregnated various polymer such as coloring agent, anticorrisive agent, fire retardant, modifier to moor wood, log that can the impregnation process full range of sizes.
The medicated liquid pressuring and injecting method that is used for Wooden modifying of the present invention, by main by frame, add the timber pressure impregnating equipment that locking oil cylinder, fluid injection band tooth seal disc, discharge opeing band tooth seal disc, collecting tank, log lifting support, seal disc lowering or hoisting gear and topping-up pump constitute, impregnate chemical reagent being no more than under the 0.8MPa pressure termination from log, the resin of log is cemented out, and main operational steps is as follows:
1), utilize the log lifting support to adjust log to the appropriate location, utilize seal disc lifting handwheel to adjust fluid injection band tooth seal disc and discharge opeing band tooth seal disc and log two ends and align;
2), utilize and to add locking oil cylinder fluid injection band tooth seal disc and discharge opeing band tooth seal disc are snapped in the log two ends;
3), from the chemical reagent of medical solution pool under the pressure effect of topping-up pump, the fluid injection band tooth seal disc that enters log one end by flexible pipe enters log, and enters the resin collecting pit from the resin that the other end of log is extruded by flexible pipe;
4), when the other end of log no longer flows out resin, open pneumatic unloader and pressurization conversion valve, the valve closing that will lead to resin collecting pit pipe simultaneously, from the chemical reagent of medical solution pool under the effect of topping-up pump pressure, the discharge opeing band tooth seal disc that enters the log other end by flexible pipe is injected into log, from the chemical reagent backflow medical solution pool of log other end outflow.
By accompanying drawing the present invention can be described in further detail.
Description of drawings
Fig. 1 has showed the equipment cross-sectional structure figure of the method for the invention.
This equipment comprises frame, adds locking oil cylinder, fluid injection band tooth seal disc, discharge opeing seal disc, collecting tank, log lifting support, seal disc lifting handwheel and topping-up pump.
