Description

A kind of degreasing method of pine veneer
Technical field
The present invention relates to a kind of degreasing method of pine veneer, specifically, relate to a kind of method that removes rosin in the pine veneer.
Background technology
At present, various pines are because the difference of its wood property, rosin content and inclusion, degreasing method is variant slightly, but current degreasing pinewoods method and technology can be concluded five kinds: (1) alkali lye saponification method, (2) solvent extraction, (3) catalyst polymerization, (4) high temperature drying method, (5) boulton process.
Generally, usually adopt two or more degreasing method to combine, but manufacturer is unsatisfactory in actual applications in order to improve degreasing effect.As the degreasing pinewoods rate of utilizing the alkali lye saponification method to handle is low, easy to change, the gloss dimness, and wastewater problem is not basic yet to be solved, and has hindered the development that the pine wood products is produced.
In sum,, obtained considerable progress, also had problems, can not satisfy the requirement in enterprise and market at aspects such as degreasing rate, the anti-variable color processing of degreasing material and degreasing depth though developed many methods in that degreasing pinewoods is technical at present both at home and abroad.Simultaneously, on present degreasing pinewoods theory and technological development, also there are two problems of obviously being badly in need of research:
At first, related in the timber process of manufacture relevant with degreaser infiltration all is non-steady-state permeation process, and the parameter of promptly describing process is the amount relevant with the time.But model in the past is too idealized, and uses steady-state flow data fitting unstable state infiltration mostly.Therefore, set up a theoretical model that meets timber unstable state degreaser infiltration real process, design suitable unstable state degreaser permeability experimental technique, this is an all very important job in theoretical and production application.
Secondly, because measuring large scale test specimen degreaser infiltration coefficient has any problem in practical operation, and the research about the degreasing infiltration all is based on laboratory scale small size test specimen at present, add that the infiltrative variation of degreaser is very big, small size test specimen degreaser permeability has certain limitation in the application of reality, is difficult to the accurately actual degreaser Penetration Signature of reflection large scale test specimen.Thereby the degreaser saturated model of structure large scale timber test specimen, study its permeability, prediction and estimation large scale timber test specimen degreaser infiltration coefficient, can shorten the gap of experimental study and production practices, more effectively be applied in the relevant production reality of timber industry, avoid " large scale effect " to take place.
Therefore, utilize modern test, analysis means, carry out theory and technological innovation, new technology that research and development low cost, high efficiency, low pollution, wood color are fresh, technology maturation and industrialization level are high and new technology are development trends from now on.Applicant of the present invention carries out system research to the pine veneer degreasing, obtains to utilize the technology of efficient degreasing, and this can change the situation that China's pine poor benefit is utilized, and also the sustainable development to China Forest has crucial meaning.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly is easy to realize, the degreasing method of easy to operate, environmental protection, pine veneer that production cost is low.
In order to solve the problems of the technologies described above, the degreasing method of pine veneer provided by the invention comprises the steps:
(1), degreaser preparation: utilize ethanol and benzene, according to volume V Ethanol: V Benzene=1.5～2.5: 1 is made into degreaser;
(2), pine veneer is got the raw materials ready: select the thick pine veneer of 0.05～2.5mm;
(3), ungrease treatment: degreaser is filled the degreasing pond, down auxiliary at ultrasonic wave then, 1～10 pine veneer is fixed on the conveyer belt, from the degreasing pond, transport, require pine veneer under the liquid level of degreaser, pine veneer immerse the degreasing liquid level to the time of exposing the degreasing liquid level be 10～60min.
Pine veneer is handled 60min in degreaser, degreasing rate is lower than at 70% o'clock, changes degreaser, and waste and old degreaser carries out distillating recovering solvent, raffinate and the residue rosin for deviating from from pine veneer.
Pine veneer described in the above-mentioned steps (2) is meant the veneer of rotary-cut or slicing, and breadth does not have specific (special) requirements.
Conveyer belt described in the above-mentioned steps (3) is meant the belt or the steel band of anti-degreaser corrosion.
Described distillation is meant under normal pressure and 75～85 ℃, or under vacuum is 0.01Mpa and 45～55 ℃, the separated from solvent in the waste and old degreaser come out.
Adopt the degreasing method of the pine veneer of technique scheme, be to rely on benzene/alcoholic solution the rosin in the veneer to be deviate to the dissolving of rosin, the present invention can make the pine veneer degreasing rate reach more than 70%, wood color keeps the fresh wood color of pine, physico-mechanical properties descends less, can satisfy the requirement of furniture fully.This invention have be easy to realize, easy to operate, production cost is low, what is more important utilizes this technology not produce waste water, improves the added value of pine, job-creation helps promoting artificial forest resource and ecological, social harmonious development.
In sum, the present invention be a kind ofly be easy to realize, the degreasing method of easy to operate, environmental protection, pine veneer that production cost is low.
