Product Details
International standard wood anticorrosion treatment tankTechnological process profileIn the process of wood preservative treatment,the most important and effective way is pressurization.Putting the wood into the wood preservative tank and injecting the antiseptic inside of the wood by pressure.
Operating steps
1.Initial vacuum:vacuum first before adding the antiseptic,in order to draw out the air in the wood so that the antiseptic steeping the wood thoroughly.Generally the vacuum degree is 79.8-90kpa,steeping time own to the different products(generally 15-60 minutes),when the tank become vacuum tank,part of air in the wood is draw out, then the antiseptic can go into the wood more fluently. |
2.Add the antiseptic:in the case of vacuum,adding the antiseptic by valve,to make sure the air stayinside of the wood. |
3.Increase pressure:relief the vacuum when the tank is filled with antiseptic,then increase the pressure slowly to 1.01.4Mpa and stay at this press until prescribed antiseptic are totallyinjected into the wood. |
4.Pressure relief,removal of preservatives:when the prescribed antiseptic are totally absorbed,thendischarge the pressure inside the tank,there may be a certain degree of recoil at this moment(5-15%) |
5.Final vacuum:when the antiseptic are discharged in the tank,then vacuumized the tank,in order to extract the excess antiseptic out of the cell and surface of the wood to reduce dropping liquid when take out the wood. |
6.Open the door and take out the wood when the atmosphere restored |
Principle:
It combines vacuum and pressurizing. |
A:Vacuum: suck out air out of tank and wood cells, which makes it easy for chemical agent to be absorbed into wood cell. |
B: Pressurizing: help chemical agent go into wood cell with pressure. |
