Production method of homogeneous carbonized wood using masson pine wood as raw material

Abstract

The production method of homogeneous carbonized wood using masson pine wood as raw material belongs to the field of forestry product processing technology, and is completed by degreasing and carbonization. Excessive carbonization of the outer layer at high temperature due to excessive grease overflow causes uneven carbonization inside and outside, laying a solid foundation for achieving homogeneous carbonization; different heating and cooling methods are adopted according to different materials and color targets of masson pine raw materials Speed, carbonization temperature and carbonization time, so that the masson pine wood can be carbonized to the same degree from the outside to the inside, so that the hygroscopicity, dimensional stability, mechanical properties, corrosion resistance, hardness and compression resistance of each part, The properties of gluing and surface finishing, especially the color, all show the same good characteristics and achieve a true homogeneous carbonization effect, which greatly expands the application field of masson pine wood and improves the application value and economic benefits.

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.
