Description
Technical field
The invention belongs to the production field of rosin, be specifically related to a kind of working method of rosin.
Background technology
Rosin is by the oozy resin of conifer trunk, belongs to the product of trees physiological activity, is viscous liquid or blocks of solid in air, contains abundant rosin and turps.Rosin and turps are a kind of widely used chemical industry basic raw materials, and wherein, rosin is water insoluble, have anticorrosion, insulation, the performance such as bonding, softening, are the main supplementary materials of each Chemicals such as synthetic rubber, paint, soap, emulsifying agent, papermaking.Turps is a kind of colourless or flaxen volatile oil, is widely used in the industries such as paint, process hides.
In recent years, rosin and terebinthine demand present the trend of increase year after year, and due to the reason of the aspects such as now environmental pollution, cause the of low quality of starting material rosin, cause rosin and the turps quality prepared according to existing production method can not meet the Production requirement of downstream industry, become and be badly in need of the technical barrier that solves so prepare up-to-standard rosin and turps.Another existing rosin working method exists the shortcoming that can not remove well impurity in rosin, causes obtained rosin and the turps quality product can not be up to standard, the shortcoming such as also exist rosin and turps output is not high, active constituent content is low.
Summary of the invention
Main purpose of the present invention has been to provide a kind of working method of rosin, and rosin and the turps that can make rosin obtain after processing are superior in quality, meet Production requirement.
The technical solution used in the present invention is a kind of working method of rosin, comprises the following steps:
A, dissolving: adopt lysate to dissolve in rosin, component and the weight percent content of described lysate comprise: 55%～82% turps, 17.5%～44.5% water and 0.1%～0.5% oxalic acid;
B, clarification, coarse filtration: the Oleoresin after dissolving is inserted in transition pot and clarified, and then coarse filtration, obtains coarse filtration liquid;
C, pickling: add oxalic acid to wash;
D, washing: add hot water to wash;
E, clarification, essence filter: insert again in transition pot and clarify, then essence filter;
F, add thermal distillation: insert in rectifying tower and add thermal distillation, obtain respectively rosin and terebinthine finished product.
As preferably, the weight that in described step a, lysate adds is 30%～40% of described rosin weight.
As preferably, in described step b, coarse filtration adopts 60 object filter screens to filter.
As preferably, the weight that adds oxalic acid in described step c is 0.1%～0.2% of described coarse filtration liquid weight.
As preferably, in described steps d, the temperature of hot water is 70～80 DEG C.
As preferably, in described step e, essence filter adopts 120 object filter screens to filter.
As preferably, the Heating temperature in described step f is 170～175 DEG C.
Beneficial effect of the present invention is: (1) adopts after working method of the present invention, and rosin and the turps that can make rosin obtain after processing are superior in quality, thereby ensures the Production requirement of downstream industry; (2) turps that the present invention obtains, can recirculation be used for dissolving rosin, has saved production cost, and has ensured without the adding of tramp material, thereby the quality of rosin is improved greatly; (3) working method of the present invention adopts the lysate of turps, water and oxalic acid composition to dissolve rosin, and wherein turps can reduce fat liquid concentration and viscosity, is conducive to rosin and dissolves and clarify; Water can dissolve the water-soluble foreign matter in rosin, thereby well removes impurity; Oxalic acid can make resinous acid molysite dark in resin become water miscible material, thereby is convenient to remove impurity; (4) the inventive method is carried out respectively coarse filtration and essence filter to fat liquid, can remove well the small foreign matters such as preserved egg, pine moth and bark in fat liquid, make process obtain rosin and turps final product quality better; (5) the inventive method adopts hot water to wash, and can remove well the foreign material such as water-soluble foreign matter and separation of sediment; Carry out pickling and can remove further foreign matter, ensure quality product; (6) the inventive method adopts the complete processing of clarification, is to utilize the difference in specific gravity of fat liquid, water and impurity to carry out purified lipase liquid, thereby can removes better foreign matter.
