Anonymous users2024-02-09The main component of wood tar is wood creosote oil, which is usually obtained by distilling tar from non-greasy wood, treating it with sodium hydroxide, re-acidifying and re-distilling to separate it from other components. Wood creosote is a colorless liquid, but it is colored, smoky and corrosive under the action of air and light, and is mainly used as a disinfectant and preservative. Wood tar is an organic compound with high hydrocarbons, acids and phenols, and creosote, antipolymerizer, flotation foaming agent, wood asphalt and other products can be obtained after processing.
It can also be used in pharmaceutical, synthetic rubber and metallurgical sectors. Wood tar: a product that is discharged when wood (softwood or other wood) is carbonized in a charcoal kiln (e.g., Swedish tar or pine tar) or distilled in a retort or furnace (distilled tar).
Distilled tar can be obtained directly from the precipitation of scorched wood water (precipitated tar) or by distillation of scorched wood water (tar is partially dissolved) (dissolved tar). The portion of the distilled tar obtained after further distillation to remove some of the volatile oils is also included in this tariff code. All of these tars are complex mixtures of hydrocarbons, phenols and their homologues, glycaldehydes, acetic acids, and various other products.
Tar made from grease-filled wood is different from tar made from non-grease wood that contains resin-distilled products (terpenes, rosin oil, etc.), it is a viscous product that varies in color from brownish-yellow to dark brown. These products, which are obtained by simple dehydration or partial distillation, are mainly used for impregnation of marine cables, as plasticizers in the rubber industry, for caulking glue and for medicine. Tar made from non-grease wood is a thick, brownish-black liquid that can be distilled or otherwise treated to produce a variety of by-products (xylogic oil, guaiacol, etc.).
Juniper oil, also known as pine tar, is used in pharmaceuticals and soap making, and is also classified under this tax code. (2) Refined wood tar, obtained by distilling wood tar. Among them, the light oil (containing aliphatic hydrocarbons, terpenes and higher ketones) is used to make sheep medicated bath water and horticultural sprays, while the heavy oil (containing aliphatic hydrocarbons and aromatic hydrocarbons, higher ketones and higher phenols) is used to impregnate wood and extract wood creosote oil.
According to its characteristics, the decreosote obtained from creosote extraction can be used for flotation method to select minerals, make pesticides, and be used as solvents and fuels. (3) Wood creosote is the main component of wood tar, which is usually prepared by distilling tar from non-fat-filled wood, treating it with sodium hydroxide, re-acidifying and re-distilling to separate it from other components. Wood creosote is a colorless liquid, but it is colored, smoky and corrosive under the action of air and light, and is mainly used as a disinfectant and preservative.
However, it is not to be confused with creosote or mineral creosote, which are classified as tariff numbers. 2. Rough wood essence is obtained by treating scorched wood water. It is a light yellow liquid with a burnt odor, usually containing 70 90 methanol and different proportions of acetone and other ketones (usually 8 20), and also contains other impurities (methyl acetate, higher alcohols, tar-like substances, etc.).
Certain crude wood is used as an ethanol denaturant.

Anonymous users2024-02-08Brother, in addition to wood tar, the discharge of the mechanism charcoal plant is wood vinegar, and the long-term discharge to the fish pond is equivalent to making the water of the fish pond acidic, do you want to soak the fish in vinegar without dying?
If the mechanism charcoal smoke is too large and the residents have opinions, they can install a set of flue gas ** system to solve the problem, that is, about six or seven thousand yuan, once and for all.
