Description
Przedmiotem wynalazku jest sposób chlodzenia mieszanek gumowych w mieszalniku zamknietym. Wedlug znanych metod chlodzenie mieszanek gumowych polegalo na chlodzeniu posrednim poprzez sciany komory i wirników mieszalnika oraz wode, która odbierala nadmiar ciepla z mieszanki. Chlodzono mieszanke równiej poprzez przetrzymywanie jej po wyladowaniu z miksera w otwartej przestrzeni spryskujac ja strumieniem wody lub mgla powietrzno-wodna. W metodach tych wada byla slaba efektywnosc odbierania ciepla z mieszanki oraz wydluzenie cyklu produkcyjnego wykonywania mieszanki. Wad tych nie posiada sposób wedlug wynalazku, który polega na chlodzeniu mieszanki w sposób bezposredni w trakcie jej wytwarzania albo chlodzenia po wy¬ tworzeniu poprzez odbiór z niej ciepla przez wprowadzenie do mieszanki stalego dwutlenku wegla.W sposobie wedlug wynalazku dodatkowa korzyscia jest uzyskanie mieszanki o wiekszym stopniu wymie¬ szania oraz mozliwosc regulacji intensywnosci schladzania mieszanki gumowej przez odpowiedni dobór proporcji dwutlenku wegla do masy mieszanki.Przyklad I. Do mieszalnika o pojemnosci 50 dcm3 wprowadza sie 29,6 kg kauczuku izoprenowego, 20,8 kg kaolinu, 0,37 kg stearyny, 0,65 kg tlenku cynku, 1,63 kg parafiny, 0,50 kg kwasu benzoesowego, sklad¬ niki te miesza sie przez okolo 2 minut, nastepnie wprowadza sie 10,0 kg stalego dwutlenku wegla i 9,2 kg siar¬ czanu baru, skladniki te miesza sie z poprzednimi przez 1 minute a nastepnie wprowadza sie 0,14 kg przyspie¬ szacza T oraz 0,73 kg siarki i miesza sie przez okolo 20 sekund. Gotowa mieszanke o zadanej temperaturze okolo 75°C wyladowuje sie.Przyklad II. Do mieszalnika o pojemnosci 50 dcm3 wprowadza sie wczesniej wykonana mieszanke z zespolem wulkanizacyjnym w ilosci 65,0 kg i miesza przez 1 minute, nastepnie wprowadza sie 10,0 kg stalegp dwutlenku wegla i miesza sie przez 45 sekund po czym wyladowuje mieszanke o temperaturze okolo 80°C.Zastrzezenie patentowe Sposób chlodzenia mieszanek gumowych w trakcie ich wytwarzania albo przetwarzania w mieszalniku zam¬ knietym, znamienny tym, ze cieplo z mieszanki odbierane jest przez staly dwutlenek wegla wprowadzq- - ny w trakcie jej wytwarzania i równomiernie rozmieszczony w jej masie poprzez mechaniczne mieszanie. \ PLThe subject of the invention is a method of cooling rubber mixtures in a closed mixer. According to known methods, the cooling of rubber mixtures consisted of indirect cooling through the walls of the chamber and mixer rotors and water, which received the excess heat from the mixture. The mixture was cooled more evenly by keeping it in an open space after discharging it from the mixer by spraying it with a stream of water or air-water mist. The disadvantages of these methods were the poor efficiency of receiving heat from the mixture and the extension of the production cycle of the mixture. The method according to the invention, which consists in cooling the mixture directly during its production, or cooling after its production by removing heat from it by introducing solid carbon dioxide into the mixture, does not have these disadvantages. The method according to the invention provides an additional advantage of obtaining a mixture with a greater degree of mixing and the ability to regulate the intensity of cooling the rubber mixture by appropriate selection of the proportion of carbon dioxide to the mass of the mixture. Example I. 29.6 kg of isoprene rubber, 20.8 kg of kaolin, 0.37 kg of stearin are introduced into the mixer with a capacity of 50 dcm3. , 0.65 kg of zinc oxide, 1.63 kg of paraffin, 0.50 kg of benzoic acid, these ingredients are mixed for about 2 minutes, then 10.0 kg of solid carbon dioxide and 9.2 kg of sulfate are added barium, these components are mixed with the previous ones for 1 minute and then 0.14 kg of the accelerator T and 0.73 kg of sulfur are introduced and mixed for about 20 seconds. Ready mix with a set temperature of around 75 ° C is discharged. The mixer with a capacity of 50 dcm3 is filled with the previously made mixture with a vulcanization unit in the amount of 65.0 kg and mixed for 1 minute, then 10.0 kg of solid carbon dioxide is introduced and mixed for 45 seconds, then the mixture is discharged at a temperature of about 80 ° C. Patent claim A method of cooling rubber mixtures during their production or processing in a closed mixer, characterized in that the heat from the mixture is received by the solid carbon dioxide introduced during its production and evenly distributed in its mass by mechanical mixing. \ PL
