Knowledge of preservative wood manufacturers

Wood is a kind of stone that people began to use. It is also a natural resource that can be recycled and dissolved in the four major raw materials (concrete, wood and plastic) in today's society. It has small capacity, high compressive strength, anti-seismic grade, low thermal conductivity, good dielectric strength, impact resistance, strong service performance, ductility and arrogance, and beautiful texture, The characteristics of physical and mental health, environmental protection and easy production and processing make it ideal indoor and outdoor building decoration materials and building decoration materials; In addition, because of the renewable wood, wood is also a kind of energy-saving decorative building materials.

In the situation of the increasing scarcity of natural resources in the world, as renewable energy, the effective use of wood should first identify with the sustainable development trend of mountains and forests, so as to maintain the ivory balance of the world. Increasing the service life of wood and saving natural resources have been the pursuit of contemporary wood and engineering construction industry. CCA / ACQ and other vacuum pumps are more commonly used in Japanese capitalist countries, which is a reasonable anti-corrosion technology for wood; After the vacuum pump charging, it can reasonably control the corrosion of various Aspergillus flavus, white ants, mahelon drill and microbial strains on wood.

In addition to a few pure eco-corrosion-resistant wood materials, the wood which is filled by vacuum pump is called anticorrosive wood in the industry at present, and it can be used for 30-50 years in geographical environment; Other methods such as brush coating and bubble dip are attributed to the target that can not be cleaned and can not be truly anti-corrosion; The different ways; After the saws of wood sawn by filling and pressing, some additives of the side materials will penetrate above 85% (but the penetration of oil and root materials will be difficult); If the solution is not filled with pressure, such as brush coating, bubble immersion, additives always float on the surface of wood, and the original color of wood will be displayed after sawing; ACQ filling wood is light green, CCA is light green. The application of anti-corrosion wood in outdoor natural environment and how to maintain the actual effect of external type Chinese anti-corrosion wood food belongs to the new field. At present, the field is not very standard. Most processing plants basically adopt the non air drying plate (when the moisture content exceeds 30%, the actual effect of pressure filling and infiltration is not significant), and the first is to accelerate the production cycle, Second, control cost; Some customers also have a short delivery time, which causes some processing plants to make good quality, reduce the production process, deliver in a hurry, and the quality of anti-corrosion cannot be guaranteed. Needless to say, after the construction of the project, the appearance will even occur serious crack, shrinkage, and specification will be reduced; In order to reduce the deformation level of wood in the open air, it is suggested that the moisture content should be controlled below 20% during the construction. If the outdoor drying project can be constructed during the rush period, in addition, the probability of wood cracking deformation can be reduced by applying outdoor maintenance building coating after the construction.
