The LOSP (Light Organic Solvent Preservative) wood treatment system is a method of treating wood (with moisture content < 20%) using light organic solvents to protect it from insect attack, mold, and decay due to moist environmental conditions. LOSP is a typical method for wood preservation, especially for outdoor applications or in high moisture environments.
The treated wood must be completely free from decay, insect infestation, and excessive resin content. Ideally, the wood should have been kiln-dried to at least 20% moisture content and be in its final form and shape with all machining and sawing processes completed before treatment. LOSP treatment for wood involves immersing the preservative into the wood using treatment programs developed by European experts such as VacVac, VacVacPres, TriVac, Lowry Rueping. The treatment programs are controlled to optimize the effectiveness of wood impregnation with LOSP solvent and ensure that the preservative does not leak out or pose hazards to humans.
The LOSP wood treatment system is equipped with wood handling carts to move wood into treatment tanks controlled by electricity. Control software records treatment cycles, provides charts, and reports data for each cycle. The system can qualitatively, quantitatively, and output data on absorbed preservative (liters/m3) in treated wood blocks.
Implementation: During the LOSP wood treatment process, wood is placed in a specialized treatment system or in a treatment tank. Light organic solvents, often derivatives of petroleum such as hydrocarbons or oil-like compounds, are used to carry the preservative into the wood structure. Then, the treatment process relies on the diffusion of the preservative into the wood structure through solvent absorption.
Advantages:
Effective Protection: The LOSP wood treatment system provides good protection against insect attack, mold, and the effects of moisture. Comprehensive Protection: This method allows the preservative to penetrate deep into the wood, providing comprehensive protection. Uniform Penetration: LOSP penetrates evenly into the wood structure, helping prevent the growth of harmful molds and insects. Environmentally Friendly: LOSP can reduce the need for stronger chemical preservatives, helping decrease the consumption of hazardous compounds. High Durability: Wood treated with LOSP typically exhibits increased resistance to decay and maintains high durability in moist environments.
Limitations:
Solvent Evaporation: One limitation of LOSP is the solvent's tendency to evaporate after treatment, which can lead to environmental and safety issues. Energy Consumption: The LOSP wood treatment process may require significant energy consumption. Limited Wood Species Options: Not all wood species are suitable for LOSP treatment, and selecting the appropriate wood species is important.
The LOSP Thiên Hưng wood treatment system is an efficient method of wood preservation widely used in the wood industry to produce products resistant to moisture and insect attack.
