Precautions for installation of anticorrosive wood engineering
1. When installing anti-corrosion wood, there should be a gap of 0.2-1cm between the anti-corrosion wood (the size of the gap is determined according to the moisture content of the wood. When the moisture content of the wood is greater than 30%, the gap should not exceed 0.8cm to avoid water accumulation in rainy days. Anticorrosive wood expansion; for square columns with a thickness greater than 50mm or 90mm, grooves can be made on the back to reduce cracking.
2. The stainless steel, hot-dip galvanized or copper should be drilled in advance (mainly to avoid future corrosion and affect the firmness of the connection) to avoid cracking of the anticorrosive wood.
3. The existing size and shape of the preservative wood should be used as much as possible, and the damaged part should be coated with preservatives and outdoor protective coatings, because the preservative wood itself is a semi-finished product. After the moisture content of the wood is reduced to less than 20%, the rough part Polish again. After paving, the outdoor protective paint can also be painted after cleaning the surface (if there is a protective paint color, it should be stirred well). If it rains, cover it with a plastic sheet and apply outdoor protective paint after cleaning it up. Note: Avoid rain within 24 hours after painting.
4. Apply external protective coating or oil-based paint on the surface of anti-corrosion wood (only once) to ach
