What is the heat treated wood?
The heat treated wood is wood that has been exposed to high temperatures. The purpose of the heat treatment is to improve the usefulness of the material. The heat treatment usually limits the amount of reduction or swelling of the wood after installation. It also prevents rot by limiting the amount of sugar available to mushrooms to which it can grow.
Ordinary types of heat -treated wood include pine, aspen and spruce. These types of heat -treated wood are usually used for floors, walls or ceiling panels. Heat -treated wood is also used to make furniture. The temperature at which the wood is treated is about 392 ° F (200 ° C). Completion of the process usually takes 24 hours. In general, the temperature is around 133 ° F (56 ° C) and the duration is about 30 minutes. This is the recommendation of international standards for phytosanite measures (ISPM) 15, which IS international export standard. The primary focus is the elimination of pests who could live in the wood structure. Nematoda Pinewood and Asian with a long corner beetle are two insects whoEr is commonly found in wooden pallets.
Officially ISPM 15 requires both hard wood and soft wood treated with heat. All types of wood packaging material should have a stamp, which indicates it in accordance with the standard of wood treated with heat. Shipments that lack a stamp must not pass through other countries. It is recommended to warm up the treatment of all wood packaging materials to avoid delay in delivery.
The longer and more intensive duration of heating needed for wood used for production products or building houses is needed to ensure that the wood is in the best condition. One of the advantages of heating is that the water inside the wood. This reduces the amount of wood reduction during its life.
Another advantage is that the heating converts sugar inside the wood into an unusable form. This prevents mushroom accumulation in the structure and reduces rot. In addition, JSOU during heating the natural protective compounds inside the wood. It also prevents wood rot.
Heat processing is an effective way to increase the life of wood or wood structure. It reduces problems that could occur later, including rot and shrinkage. Approximately 130 countries received the ISPM 15 standard for wood wrapping materials.
