If there is no correct laying method and accurate theoretical knowledge, the service life of Shandong anticorrosive wood will be greatly reduced. Then, how to improve the anti-aging properties of antiseptic wood?
1、 The general outdoor wood protective coating is permeable. A protective film will be formed on the wood fiber, which can effectively prevent the erosion of water on the wood. The cleaning can be cleaned with general detergent and tools can be brushed. Maintenance shall be carried out once every 1 to 1.5 years, which can be brushed with special wood water-based coating or oil-based coating.
2、 The existing size and shape shall be used as much as possible, and the damaged parts shall be painted with preservatives and outdoor protective coatings; Since the anticorrosive wood itself is a semi-finished product, the rough part can be sanded again after the wood moisture content is reduced to less than 20%. If you want to have better effect, you can also brush outdoor protective coating after the surface is cleaned (if there is colored protective coating, it should be fully mixed). In case of overcast and rainy days, cover it with plastic cloth first, and then brush outdoor protective coating after it clears up.
Note: rain shall be avoided within 24 hours after painting
After the surface is painted with outdoor protective coating or oil-based coating (only one time), in order to achieve the effect, avoid personnel walking or heavy objects moving within 48 hours, so as not to damage the protective film formed on the anti-corrosion wood surface. If you want to achieve better anti dirt effect, if necessary, the surface layer shall be treated with two layers of special outdoor varnish.
3、 Treatment of wood structure base course: the air circulation between anti-corrosion wood and the ground shall be fully maintained in the design and construction, which can more effectively prolong the service life of wood structure base course.
When making and installing anti-corrosion wood, a gap of 0.2-1cm shall be left between the anti-corrosion wood (the gap size shall be determined according to the moisture content of wood, and it shall not exceed 0.8cm when the moisture content of wood exceeds 30%) to avoid ponding and expansion of anti-corrosion wood in rainy days; For square columns with a thickness of more than 50mm or more than 90mm, a groove can be opened on the back to reduce cracking. The hardware shall be connected with stainless steel, hot-dip galvanized or copper. Please drill holes in advance during installation to avoid cracking of Shandong anti-corrosion wood.
1. Stainless steel cross screws are used to connect with the keel on the front of the anti-corrosion wood;
2. The keel is fixed on the reverse side of the anti-corrosion wood with screws, and several pieces are assembled into a whole, which not only does not damage the ground structure, but also can be disassembled and cleaned freely;
3. Suspended paving, keel leveling on the ground can be connected into frame / well frame structure, and then anti-corrosion wood is paved.
Five, fixed shop: try to use the expansion screws to fix the keel on the ground. The expanded wire is nylon material (anti-aging is better), the iron expansion pipe should be painted with anti rust paint, and then lay up the anti rot wood.
