Description

Przedmiotem wynalazku niniejszego jest sposób regeneracji kauczuku, zwla¬ szcza kauczuku zawartego w zuzytych o- pomach kól pneumatycznych.Sposób niniejszy polaga w zasadzie na wytwarzaniu pewnego rodzaju, oleju lub esencji przez destylacje odpadków niepod- legajacych regeneracji, jak np. nasad pneu¬ matycznych kól samochodowych, starych przewodów kauczukowych do gazu, wody, kól pneumatycznych rowerowych i tym po¬ dobnych przedmiotów, a nastepnie na im¬ pregnowaniu tym olejem lub esencja opjn pneumatycznych do kól samochodowych, pocietych uprzednio na paski lub wieksze albo mniejsze kawalki; impregnowane w talki sposób kawalki zostaja po ukonczeniu impregnowania (t. j. po zaabsorbowaniu calej ilosci oleju lub esencji) zanurzone w kwasie solnym, najlepiej stezonym, który ma za zadanie przemiane pewnych czesci tego oleju lub esencji w kauczuk syntetycz¬ ny (prace Bouchardata), jak równiez cal¬ kowite zniszczenie plótna, zawarbejgo w ka¬ walkach zuzytych opon kól pneumatycz¬ nych (nalezy zauwazyc, ze zimny kwas solny nie dziala na kauczuk).Po zakonczeniu polimeryzacji esencji (w ciagu 15 — 20 dni) nieco lepka masa zostaje plókana w duzej ilosci wody celem usuniecia nadmiaru kwasu, poczem prze¬ chodzi na walce do mycia lub odoedzaniacelem usuniecia odpadków plótna, spalone¬ go przez kwas; odpadki te wypadaja z walca w postaci pylu. Otrzymany w taki sposób kauczuk moze sluzyc, z wyjatkiem rozpuszczania, do wszystkich pozostalych celów, do których stosuje sie kauczuk plan¬ tacyjny. PLThe present invention relates to a process for the regeneration of rubber, in particular rubber contained in used pneumatic pulleys. The present method essentially involves the production of some kind of oil or essence by distilling non-reclaimable waste, such as, for example, pneumatic wheel bases. automotive, old rubber pipes for gas, water, bicycle pneumatic wheels and the like, and then impregnated with this oil or the essence of pneumatic options for car wheels, previously cut into strips or larger or smaller pieces; after the impregnation is completed (i.e. after the entire amount of oil or essence has been absorbed), the pieces are immersed in hydrochloric acid, preferably concentrated, which is to transform some parts of this oil or essence into synthetic rubber (Bouchardat's work), as well as complete destruction of the cloth contained in the battles of the worn pneumatic tires (note that cold hydrochloric acid does not affect the rubber). After completion of the polymerization of the essence (within 15 - 20 days), the slightly sticky mass becomes fluffed for a long time. the amount of water to remove excess acid, then goes to washing rollers or drainage to remove linen scraps which have been burnt by acid; this waste falls out of the roller as dust. The rubber obtained in this way can be used, with the exception of dissolution, for all other purposes for which the vegetation rubber is used. PL

Claim, A method of cold recovery of rubber, in particular rubber contained in worn pneumatic tires, a significant amount of oil or essence produced by the distillation of waste unsuitable for regeneration, the essence of which is used to impregnate the previously cut worn pneumatic tires which are then impregnated in hydrochloric acid, preferably concentrated, in order to obtain synthetic rubber while destroying the cloth, making the cloth blackened. in this way, the somewhat sticky mass is, after complete absorption of the oil or essence by hydrochloric acid, washed with plenty of water and finally passed to the washing or decontamination roller, Syndicat Franco-Neerlandais.
