Ukukhiqizwa kwemikhiqizo yenjoloba

Ngesikhathi senqubo yokulungiselela okubonakalayo eluhlaza, izithako kumele zibhekwe ngokunembile ngokuya ngefomula. Ukuze irabha eliluhlaza kanye ne-ejenti ehlanganisiwe ukuxubana ngokulinganayo, izinto ezithile zokwakha zidinga ukucutshungulwa:

Irabha eluhlaza kufanele ithathwe egumbini lokumisa le-60-70 ℃ ngaphambi kokusikwa futhi liphuke izingcezu ezincane;

Vimba njengezengezo ezinjengepharafini, i-stearic acid, i-rosin, njll. Kudingeka uchotshozwe;

Uma i-powked compound iqukethe ukungcola kwemishini noma izinhlayiya ezihlanganayo, kudinga ukubonwa futhi kususwe;

Izengezo eziwuketshezi (i-pine tar, i-coumarone) idinga ukufudumeza, ukuncibilika, ukuhwamuka kwamanzi nokuhlunga;

I-ejenti ehlanganisiwe idinga ukomiswa, ngaphandle kwalokho ithambekele ekuhlolweni futhi ayikwazi ukuhlakazeka ngokuxuba, okuholela kuma-bubble ngesikhathi se-Vulcanization futhi kuthinta ikhwalithi yomkhiqizo;

3. Ukucwengisisa

I-RAW RUBBER i-Elastic futhi ayinazo izakhiwo ezidingekayo (i-plastiki) yokucutshungulwa, okwenza kube nzima ukucubungula. Ukuze kuthuthukiswe i-plastiki yayo, kuyadingeka ukucwilisa irabha eluhlaza; Ngale ndlela, i-ejenti ehlanganisiwe ihlakazeka kalula enjoloba eluhlaza ngesikhathi sokuxuba; Ngasikhathi sinye, ngesikhathi senqubo yokugoqa nokwakha, futhi kuyasiza ukuthuthukisa ukuvumela kwezinto zenjoloba (ukungena kwindwangu yefayibha) kanye nokwakheka. Inqubo yokonakalisa ama-molecule amade werabha enjoloba eluhlaza okokwenza i-plastity ibizwa ngokuthi yiplastiki. Kunezindlela ezimbili zokucwilisa irabha eluhlaza: Ukucwengeka kwemishini nokucwengeka okushisayo. I-Mechan Plasticing yinqubo yokwehlisa ukonakala kwama-molecule enjoloba amade futhi awuguqule esimweni sepulasitiki esisesimweni seplastiki ngokukhishwa komshini weplastiki emazingeni okushisa aphansi. I-Thermoplastic Refining inqubo yokwethula umoya oshisayo ocindezelwe enjoloba eluhlaza, okuthi, ngaphansi kwesenzo sokushisa kanye nomoya-mpilo, anciphise futhi anciphise ama-molecule amade, ngaleyo ndlela athole i-plasticity.

4. Ukuxuba

Ukuze uvumelane nezimo zokusetshenziswa ezahlukahlukene, zuza ukusebenza okuhlukile, futhi uthuthukise ukusebenza kwemikhiqizo yenjoloba futhi unciphise izindleko, kuyadingeka ukufaka izengezo ezahlukahlukene kwirabha eluhlaza. Ukuxuba kuyinqubo yokuxuba irabha eluhlaza eluhlaza nge-ejenti ehlanganisiwe bese uyibeka ku-recber mixer. Ngokuxuba okwenziwe ngomshini, i-ejenti ehlanganisiwe ihlakazeka ngokuphelele futhi ihlakazeka ngendlela efanayo enjoloba eluhlaza. Ukuxuba kuyinqubo ebalulekile ekukhiqizweni kwemikhiqizo yenjoloba. Uma ukuxuba kungafani, indima yenjoloba futhi izengezo ayinakusetshenziswa ngokuphelele, okuthinta ukusebenza komkhiqizo. Izinto zenjoloba ezitholwe ngemuva kokuxubha, ezaziwa ngokuthi irabha elixubile, kusetshenziselwa izinto eziqediwe ukukhiqiza imikhiqizo ehlukahlukene yenjoloba, eyaziwa njengezinto zenjoloba. Imvamisa ithengiswa njengempahla, futhi abathengi bangacubungula ngokuqondile futhi bavuselela izinto zenjoloba ukukhiqiza imikhiqizo edingekayo yenjoloba. Ngokusho kwamafomula ahlukile, irabha elihlanganisiwe linochungechunge lwamamaki ahlukene nezinhlobonhlobo ezinezakhiwo ezahlukahlukene, zinikeza ukukhetha.
