Description

Известные способы рекуперации органических растворителей при нанесении нитрокрасок на окрашиваемую поверхность методом пульверизации не дают положительного эффекта, так как фильтрующие системы быстро забиваютс  высокодисперсной пылью минеральных и органических пигментов и красителей, что нарушает непрерывность процесса, уменьшает производительность фильтрующей системы и повышает потери растворителей.The known methods of recovery of organic solvents when applying nitrokrasok to the surface to be painted are not beneficial by spraying because the filtering systems are quickly clogged with highly dispersed dust of mineral and organic pigments and dyes, which violates the continuity of the process, reduces the performance of the filtering system and increases the loss of solvents.

Описываемый способ устран ет указанный недостаток и заключаетс  в том, что во врем  нанесени  нитрокрасок на окрашиваемую поверхность методом пульверизации в зону улавливани  органических растворителей ввод т дополнительно нитролак в количестве от 5 до 50% от веса нитрокрасок. При пульверизации нитролака в зоне улавливани  растворителей образуютс  хлопь  коллоксилина, обладающего огромной развернутой поверхностью и кле щей способностью. На этой поверхности хлопьев осаждаетс  основна  масса высокодисперсной пыли пигментов и красителей.The described method eliminates this drawback and consists in the fact that during the deposition of nitrokrasok on the surface to be painted by the method of pulverization, an additional nitrolac in an amount from 5 to 50% by weight of nitrokrasok is introduced into the trapping zone of organic solvents. When spraying nitrolac in the solvent trapping zone, flakes of colloxylin are formed, which have a huge unfolded surface and adhesive power. On this surface of the flakes, the bulk of the finely divided dust of pigments and dyes is deposited.

Коллоксилиновые хлопь   вл ютс  своеобразными искуственными фильтрами дл  нитрокрасочной пыли, эти хлопь  при столкновении образуют более крупные частицы, и, осажда сь на поверхности матерчатых фильтров, они не забивают их пор, а, в свою очередь, фильтруют паровоздушную смесь от нитрокрасочной пыли.Kolloksilinovye flakes are a kind of artificial filters for nitrokrasochnogo dust, these flakes form larger particles during the collision, and, deposited on the surface of fabric filters, they do not clog their pores, and, in turn, filter the vapor-air mixture from nitrokrasochnoy dust.

Предмет изобретени Subject invention

Способ рекуперации органических растворителей, получаемых при испарении в процессе нанесени  нитрокрасок на окрашиваемую поверхность методом пульверизации, с созданием самофильтрующей от высокодисперсной пыли системы, отличающийс  тем, что, с целью повышени  производительности самофильтрующей системы, в зону улавливани  растворителей ввод т дополнительно распыленный нитролак в количестве от 5 до 50% от веса нитрокрасок дл  выделени  коллоксилина, создающего основу самофильтрующей системы.The method of recovery of organic solvents obtained by evaporation in the process of applying nitrokrasok to the surface to be painted by the method of spraying, creating a system that is self-filtering from highly dispersed dust, is characterized in that, in order to increase the performance of the self-filtering system, additional sprayed nitrolac is introduced in the amount 5 to 50% by weight of nitrocolors for the release of colloxylin, which forms the basis of a self-filtering system.
