Timber is put in people's pressure impregnation tank, with vacuum pump by impregnating autoclave evacuation, and keep certain time as stable
Property, extract the air in wood cell chamber out so that timber is easily modified agent dipping, and reduce the modifying agent recoil when release
Emit, retain more modifying agent in wood, keep timber saturation；
2) modifying agent is added:
In the case of not closing vacuum pump, under conditions of i.e. keeping original vacuum, add modifier solution；
3) pressurization:
After pressure impregnation tank filled it up with by modifying agent, close vacuum pump, after eliminating vacuum, apply pressure, reach required
Keep a period of time after pressure, until required modified dosage is the most profoundly by inside pressure people's timber；
4) discharge opeing:
After pressure relief, utilize the action of gravity of modifier solution, or with positive displacement pump, by the modification in pressure impregnation tank
Agent solution returns in modifier solution storage tank；
5) final vacuum:
After drained retardant solution, close all valves immediately, connect vacuum pump, start the final vacuum time；Final vacuum
Vacuum can be the same with initial vacuum, then releases vacuum, releases the modifier solution extracted out in the final vacuum stage；Open tank
Door, takes out treated timber, completing of modification.
Described 3) pressurization time use hydraulic pressure, or use air pressure.
Described 3) during pressurization or be added to till timber refusal absorbs after modifier solution.
Described 3) pressure period completes when the pressure period, during pressure release, a small amount of empty due to be compressed in timber
The expansion of gas, the modifier solution absorbed by timber in the pressure period has part now can recoil out from timber, returns
In pressure impregnation tank.
The vacuum of described final vacuum can be compared with initial vacuum, or more slightly lower, and keeps a period of time.
The beneficial effect of the invention:
The present invention is possible not only to make modifying agent enter into the deep part of material in relatively short period of time, and can utilize pressure
The size adjustment of power and vacuum enters the degree of depth and inlet, adapts to the different requirements of material character change, improve treatment effeciency and
Control cost.
The present invention makes to be full of in wood cell modifier solution, makes timber remain with the maximum amount of modifying agent.This method
Condition is harsher, can reach maximum modification agent and inhales dose and length of penetration.
