Wood Kiln Dry Seasoning Service
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method.
Woodworking: when wood is used as a construction material, whether as a structural support in a building or in woodworking objects, it will absorb or desorb moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood.
For some purposes, wood is not dried at all, and is used green. Often, wood must be in equilibrium with the air outside, as for construction wood, or the air indoors, as for wooden furniture.
Wood is air-dried or dried in a purpose built oven (kiln). Usually the wood is sawed before drying, but sometimes the log is dried whole.
Vaccum Chemical Impregnation
The introduction of chemical substances into wood in order to improve its characteristics and impart new properties. Impregnation stabilizes dimensions, increases strength and resistance to water, moisture, and chemicals, and reduces cracking. The most common methods ofimpregnation employ antiseptics, which ensure protection against wood rot and other forms of biological deterioration, and fire retardants,which prevent wood from catching fire and burning. Impregnation is used in the railroad industry, power engineering, the manufacture off frail road cars, shipbuilding, and construction.
Heat treatment As per ISPM-15 (Licence no.140)
International Standards For Phytosanitary Measures (ISPM 15) is an International Phytosanitary Measuredeveloped by the International Plant Protection Convention (IPPC) that directly addresses the need to treat wood materials of a thickness greater than 6mm, used to ship products between countries. Its main purpose is to prevent the international transport and spread of disease and insects that could negatively affect plants or ecosystems. ISPM 15 affects all woodpackaging material (pallets, crates, dunnages, etc.) requiring that they be debarked and then heat treated or fumigated withmethyl bromide and stamped or branded, with a mark of compliance. This mark of compliance is colloquially known as the "wheat stamp". Products exempt from the ISPM 15 are made from alternative material, like paper, plastic or wood panel products (i.e. OSB, hardboard, and plywood).
