Description
Изобретение относитс к способам переработки невулканизованных н слабо вулканизованных, отходов ггрорезиненной тканн на резину и тканевые обрезки нутем обработки в стиральных барабанах, роллах н подобных .ах с последуюнгим разделением на тканевые обрезки и резииу флотационным методом.The invention relates to methods for processing uncured and weakly vulcanized waste groproizinennoy fabric for rubber and fabric trimming with processing in washing drums, rolls on the similar, with subsequent separation into fabric cutting and rubber by the flotation method.
Известны снособы переработки резиново-тканевых отходов резниового производства путем их нредварительиой химической обработки, с иос.тедующим отделеиием волокна от резины флотациоииым методом. Одиамо эти способы требуют предварительного измельчени отходов, что неизбежно приводит к xTvioifbHieuHio ДЛН1ПЛ волокон.Dunnage processing of rubber-fabric waste from the production of rubbish is known by means of their chemical pretreatment, with the separation of fiber from rubber by the flotation method. Odiamo these methods require pre-grinding of waste, which inevitably leads to xTvioifbHieuHio DLN1PL fibers.
Огнчсываемый способ не требует предвл ите;н-з;1ого измельчени отходов нрорезниенной тканн при переработке их iia резину и тканевые обрезки.The fireproof method does not require a preliminary; 1st, first shredding of waste nroresnennoy fabric when processing them rubber and fabric trimming.

The mass, after it has been machined, will go: the following pages of individual pieces of fabric and rubber, while maintaining the original configuration of the segments.
Полученна смесь резиновых и тканевых обрезков в течение 30- 40 минут обрабатываетс 3-5%-ным раствором соды, отжимаетс от раствора на сите или центрифуге и затем ногружаетс в ванну с 0,5- 1,5%-ным водным раствором серной кислоты, где в течение 30-40 минут перемешиваетс .The resulting mixture of rubber and fabric scraps is treated with a 3-5% soda solution for 30-40 minutes, squeezed out of the solution on a sieve or a centrifuge and then dipped into a bath with a 0.5-1.5% aqueous solution of sulfuric acid, where it is stirred for 30-40 minutes.
Через 15-30 минут смесь расслаиваетс на резину и тканевые обрезкн , нричем ткань вснлывает вверх, а резина остаетс на дне.After 15-30 minutes, the mixture is exfoliated into rubber and tissue trimming, the fabric sticks up and the rubber remains at the bottom.
Всплывша ткань снимаетс , кислый раствор сливаетс в канализацию и резина выгружаетс со дна ванны.The floating tissue is removed, the acidic solution is drained to the sewer, and the rubber is discharged from the bottom of the bath.
Далее резина и ткань на центрифуге обезвоживаютс и обычными методами высушиваютс .Next, the centrifuge rubber and cloth are dehydrated and dried using conventional methods.
