Description
Najdluzszy czas trwania patentu do 22 kwietnia 1942 r.W patencie Nr 7417 wskazano, ze w celu wytwarzania gumy z duza iloscia mi¬ kroskopijnie malych por mozna zamiast bezposredniej przemiany na galarete prze¬ twarzac mleko kauczukowe przedewszyst- kiem w postac papki, która po pewnym czasie sama przez sie zamienia sie na jed¬ norodna lslpoista galarete, Przy takim ro¬ dzaju pracy mozliwe jest doprowadzanie papki do dowolnego ksztaltu, np, rozprze¬ strzenianie albo rozwalcowywanie jej w ksztalcie cienkich plytek, które pózniej przyjmuja wlasciwosci galarety i wkoncu zostaja zapomoca mokrej wulkanizacji przeprowadzone w stala, wysoce porowata gume. Zasadniczo przy wyborze srodka scinajacego jest, zeby nietylko przeprowa¬ dzal w pajpke mleko kauczukowe, ale by ono przez dluzszy czas w tym stanie bylo utrzy¬ mane w celu moznosci ksztaltowania. Te¬ mu warunkowi zadawalniajaco odpowiada¬ ja, jak poikaizalo 'doswiadczenie, sole man¬ ganowe, iszczególnie siarczan manganu.Dla zapobiezenia szkodliwemu oddzialy¬ waniu zwiazków manganu na gotowa gume zostaja oue usuniete zapomoca wymywania odpowicdniemi srodkami po albo przed wulkanizacja. Nie jest wprawdzie nowe, ze przy dodaniu znanego srodka scinajace¬ go w malych dawkach wystepuje stopnio-we wyrastanie lepkosci az do stanu papki, ale nie dalo sie dotychczas nigdy obserwo¬ wac przejscia papki w stan stalej spoistej galarety; galareta taka nie mogla byc wul¬ kanizowana bez odciagania wody.Przyklad. 100 cm- mleka kauczukowe¬ go miesza sie z 15 3 kwiatu siarkowego i zadaje przy poruszaniu 40 cm3 10%-go roztworu siarczanu manganu,' przy tern powstaje gesta papka, która przeprowadza sie w formy: po 1—2 godzM albo przy o- grzewanfu po krótszym czasie, nastepuje przemiana papki na stala jednorodna ga¬ larete, która nastepnie zostaje przerabia¬ na wedlug sposidbu, opisanego w patencie Nr 7417. Bezposrednio przed! wulkaniza¬ cja, albo równiez i po wulkanizacji zosta¬ je guma dokladnie wylugowana rozwod¬ nionym krasem siarkowym, a nastepnie— wymyta woda. PL PLThe longest duration of the patent until April 22, 1942. Patent No. 7417 indicates that in order to produce a gum with a large amount of microscopically small leeks, instead of converting directly to jelly, the rubber milk can be processed primarily in the form of a pulp, which after some time itself is by itself it turns into a homogeneous shiny jelly, With this type of work it is possible to bring the pulp to any shape, for example, spreading it or rolling it into the shape of thin plates, which later take on the properties of jelly and finally the wet vulcanization is forgotten solid, highly porous rubber. As a general rule, when selecting a cutting agent, it is necessary not only to spike the rubber milk into the spider, but to keep it in this state for a long time in order to be able to shape. This condition satisfactorily corresponds to experiment, manganese salts, and especially manganese sulfate. To prevent harmful effects of the manganese compounds on the finished rubber, they are removed by washing with appropriate agents after or before vulcanization. It is not new, however, that with the addition of the known cutting agent in small doses, a gradual build-up of viscosity up to a slurry occurs, but the transformation of the slurry into a solid cohesive jelly has never been observed before; such jelly could not be vulcanized without draining the water. 100 cm 3 of rubber milk is mixed with 15 3 of sulfur flower and 40 cm 3 of a 10% manganese sulphate solution are mixed with stirring. after a shorter time, the slurry is transformed into a solid, homogeneous jelly, which is then processed according to the method described in patent No. 7417. Immediately before! vulcanization, or also after vulcanization, the rubber is thoroughly leached with diluted sulfurous karst and then washed with water. PL PL
