[0002] Wood powder refers to the powder made from wood, generally referring to the leftover scraps from wood processing in furniture factories, density board factories, and multi-layer board factories. It is divided into incense-making wood powder, paper-making wood powder, and wood-plastic wood powder. Wood powder has a wide range of uses and is a new type of energy-saving and environment-friendly raw material. It can be used as raw materials for various products such as mosquito coils, leather, clothing, paper-making, electrical appliances, daily necessities, coatings, cat litter, chemical industry, insulating materials, outdoor decoration materials, and building materials. Wood powder has multiple uses and is mainly used as a filler in synthetic leather. In the wood reprocessing industry, disposable chopsticks and recycled boards such as plywood, compressed boards, multi-layer boards, and medium-density fiberboards are all made from the leftover scraps of wood. It can also be made into incensed sticks, Buddhist incense, and essence, etc., and is widely used in industries such as chemical industry, building materials, medicine, health care, breeding, food, manufacturing, power generation, etc. In addition, it can be made into mechanism charcoal for heating, and wood powder needs to be processed by a circular sieve before use.
