The use of anticorrosive wood in urban fashion
1. Anticorrosive agent. The best and most environmentally friendly antiseptic is ACQ. Most anticorrosive woods on the market use CCA. Its antisepticity is stronger than ACQ, and its environmental protection is slightly worse, but the price is relatively low. The concentration of the antiseptic agent depends on whether the concentration of the antiseptic agent can be the original concentration of 1:10. Many manufacturers say that the concentration of 1:30 is actually added to water to reduce the concentration and save costs, and its antiseptic function is greatly reduced.
2. Proof of supply of anti-corrosion wood: A. Production license for anti-corrosion pressurization treatment (because preservatives need to be used under extra protection conditions); B. Environmental protection certificate (ISO14001); C. Product quality certification system certificate (ISO9001); D. Commodity inspection certificate (imported products).
3. It can be seen from the wood as a whole whether the specification is correct and the regularity is not too faulty. Generally, the fault of the thinner board should be less than 0.5-1mm; the overall fault of the larger specification anticorrosive wood should not be greater than 2mm. Generally, it is not wrong to standardize and organize the materials under the production line. The hand-processed materials have greater faults, which will constitute construction difficulties. In addition, with regard to planed materials, we need to look at the quality of the surface planing. Smooth and natural ones are better.
4. Pressing depth of antiseptic agent. The production of antiseptic wood is to use a vacuum tank to pressurize the agent. The atmospheric pressure in the tank is not less than 16 standard atmospheres. The pressurization takes about 8 hours to press into the wood. The penetration of the class should not be less than 15mm. For Chinese fir, the penetration should be no less than 20mm.
