Method for producing homogenous carbonized wood by using pinus massoniana wood as raw material

Abstract

The invention relates to a method for producing homogenous carbonized wood by using pinus massoniana wood as a raw material, and belongs to the technical field of processing of forestry products. The method is implemented through processes of degreasing, carbonizing and the like. The method has the benefits that the pinus massoniana wood is degreased, so the phenomena of non-uniform internal and external carbonization degree caused by excessive external carbonation at high temperature when excessive grease is overflown in a carbonization process can be avoided, and foundation is laid for homogenous carbonization; different heating and cooling speed, carbonization temperature and carbonization time are adopted according to different materials and colors of the pinus massoniana raw materials, so that each part of the pinus massoniana wood can be subjected to carbonization with the same degree from outside to inside, moisture absorptivity, dimensional stability, mechanical property, corrosion resistance, hardness, pressure resistance, gluing and surface coating performance, particularly color of each part show the same good characteristic, the true homogenous effect is achieved, the application field of the pinus massoniana wood is greatly enlarged, and the application value and the economic benefit are improved.

Description

technical field [0001] The invention belongs to the technical field of forestry product processing, in particular to a production method of homogeneous carbonized wood using masson pine wood as a raw material. Background technique [0002] Carbonized wood is to carbonize wood under high temperature without any chemical agent, so that its nutrients are destroyed, so it has better anti-corrosion and insect-proof functions. Because its water-absorbing functional group hemicellulose is reorganized, the product has better physical properties. [0003] Carbonized wood is a real green and environmentally friendly product. Although the product has anti-corrosion and insect-proof properties, it does not contain any harmful substances. Animals and the environment have any negative impact; the surface of the charred wood has a dark brown aesthetic effect, and has the effect of anti-corrosion and anti-biological attack. It has low moisture content, is not easy to absorb water, stable m...

Problems solved by technology

[0005] Although deep carbonized wood can achieve anti-corrosion and moisture-proof effects, its internal and external colors are different, which seriously affects the quality of further processed products. Therefore, the applicant's research team has summarized a set of homogeneous carbonized wood after long-term research and practice. Advanced processing and production methods, not only anti-corrosion and moisture-proof, but also beautiful, uniform and durable

[0006] At present, the main species of carbonized wood are Pinus sylvestris sylvestris, hemlock, oak, etc. At present, there is no use of masson pine raw materials, mainly because the resin pipe diameter of masson pine is developed, the content of turpentine is high, and the wood deformation is large. When it is dry, it warps seriously, and it is not resistant to corrosion. When the temperature is high, it even overflows and pollutes the surface of the material, resulting in poor paint and bonding performance. Therefore, it is less used in furniture. At present, it is mainly used for building templates, mine pillars, boards, and packaging. Boxes, matchsticks, plywood, etc., or as raw materials for man-made fiberboards; however, masson pine, as a fast-growing economic forest, is widely planted in most mountainous areas of my country, and its due economic value is not sufficient due to its limitations in application fields.
