Chongqing anti-corrosion wood tells you, how to choose high-quality anti-corrosion wood?
The good and environmentally friendly preservative is ACQ. Most of the preservative wood on the market uses CCA. Its corrosion resistance is stronger than ACQ, and the environmental protection is slightly worse, but the price is relatively cheap.
Second, the concentration of antiseptics
It depends on whether the concentration of the reagent is the initial concentration of 1≤10. Many manufacturers say that using the 1:30 concentration, it is actually mixed with water, and then the concentration of the agent is reduced, the cost is saved, and the anti-corrosion performance is greatly reduced.
Third, the penetration depth of the antiseptic agent
Chongqing anticorrosive wood is made by pressure in a vacuum tank. The atmospheric pressure in the tank should not be lower than 16 standard atmospheres. The time to press into the wood should be about 8 hours, and the penetration force of the pine should not be less than 15mm. The infiltration of fir should not be less than 20 mm.
Fourth, raw materials should be dry before storage
At present, many manufacturers directly saw the raw materials and directly processed the anti-corrosion treatment. Since the raw materials are not steamed and dried, the raw materials contain a lot of water, the effect of the preservatives pressed into the wood will be greatly reduced, and the anti-corrosion effect of the wood will not be ideal. .
Designers should tailor their clothes and select anti-corrosion wood according to the owner's budget input, climate, environment, and actual wood conditions.
