Wood preservation mechanism
Antiseptic treatment is through some means, one of the necessary conditions for the elimination of microbial survival, to prevent the breeding objective. For example, water soaked wood is cut off the source of oxygen microorganism; drying methods for drying wood, is the elimination of microbial survival water; chemical anti-corrosion treatment agent is mainly to sever their nutrient source. At present, wood preservation is mainly by chemical preservatives antiseptic effect.
The anticorrosion mechanism of preservatives mainly in two aspects: mechanical isolation and mechanical isolation anticorrosion antiseptic preservative toxicity, such as decorative coating, surface protection of wood exposed to stop mining, timber and environmental factors in direct contact, to prevent the erosion of the microorganism. This method is to paint as a wood preservative, but its anti-corrosion performance is limited, not up to the preservative efficacy due. Toxic anti-corrosion is on the toxicity of preservatives to inhibit microbial growth, microbial preservatives or absorption are poisoned. The preservative mostly with toxic effect to achieve a preservative. Therefore, people pay more and more attention to the relationship between preservatives and human survival and ecological environment, chemical and biological control, non-toxic, a more effective agent will be the future direction of development.
