Izithasiselo zeRubber
Yini ama-auxilies enjoloba
I-Rubber Auxiliaries yasungulwa ekuvulekekeni kwerabha yemvelo. Ngemuva kweminyaka engaphezu kwamashumi ayisishiyagalombili yocwaningo, kuze kube yiminyaka engama-20 yekhulu lama-20 ~ 30, ngezinhlobo eziyisisekelo ze-Accelerator ye-Vulcanization 2-Mercoptobobothiazole kanye ne-P-Phenyleniamine derivalization kanye ne-antioxidant i-antio uhlelo. Izithasiselo zeRubber ngesikhathi esizinzile, i-accelerator ye-Vulcanization kanye ne-antioxidant izinhlobo ezimbili zokukhiqiza izengezo ezinkulu ezingaba ngu-4% zokusetshenziswa kwerabha eluhlaza.
Lapho r 'ngu-H, r yiqembu eli-organic; noma r 'futhi r amaqembu ezi-organic; R ', r nayo ingabanda nge-accelerator m noma usawoti wayo we-sodium, kodwa futhi nge-accelerator dm, nge-cyclohexylamine (umkhiqizo we-accelerator CZ), i-cyclohexylamine (umkhiqizo we-accelerator DZ), i-diisopropylamine (umkhiqizo we I-Accelerator DIBS), iMorpholine (Umkhiqizo we-Accelerator Nobs), iTertiary-Butyamine (umkhiqizo we-NS), njll. Ngezinqubo ezahlukahlukene. Zikhiqizwa ngezinqubo ezahlukahlukene. Ukuvuka kwabo kuqala kancane, kepha isivinini se-Vulcan siyashesha, sibizwa ngokuthi ama-accelerators ashelelayo sesikhathi sekwephuzile, futhi ikakhulukazi asetshenziswa ekukhiqizweni kwamathayi neminye imikhiqizo emikhulu yenjoloba. Emakhishini ajwayelekile, umthamo wazo kuphela kwezintathu kuphela kwalezo zi-accelerators M ne-DM (umthamo ojwayelekile wama-accelerators m ne-DM izingxenye 1 kuya ku-2). Kulesi simiso esibizwa ngokuthi "uhlelo olusebenzayo lwe-Vulcanization" (okungukuthi i-sulfur / i-hilfur accelerator inhlanganisela), umthamo ufinyelela ezingxenyeni ezi-3-5 (ezinezingxenye ze-sulfur), ezingathola ukuphepha okuhle nokuthuthukisa ukusebenza okuphelele kwenjoloba evundlekeni.
