I-Silane coupling agents iwuhlobo lwezinhlanganisela ze-organic silicon eziqukethe izinto ezimbili zamakhemikhali ezihlukene ku-molecule, ezisetshenziselwa ukuthuthukisa amandla okubopha wangempela phakathi kwama-polymers nezinto ezingaphili.Lokhu kungase kubhekisele ekwandeni kokunamathela kwangempela, kanye nokuthuthukiswa kokumanzi, izakhiwo ze-rheological, nezinye izakhiwo zokusebenza.Ama-ejenti ahlanganisayo angase abe nomthelela wokulungisa endaweni yesixhumi esibonakalayo ukuze kuthuthukiswe isendlalelo somngcele phakathi kwezigaba zezinto eziphilayo nezingaphili.
Ngakho-ke,ama-silane coupling agentsasetshenziswa kakhulu ezimbonini ezifana nokunamathelisa, okokunamathela noyinki, irabha, ukusakaza, i-fiberglass, izintambo, izindwangu, amapulasitiki, ama-filler, nokwelapha okungaphezulu.
Umkhiqizo wayo wakudala ungamelwa ifomula evamile ye-XSiR3, lapho i-X iyiqembu elingelona i-hydrolytic, okuhlanganisa amaqembu e-alkenyl (ikakhulukazi i-Vi) namaqembu e-hydrocarbon anamaqembu asebenzayo afana ne-CI ne-NH2 ekugcineni, okungukuthi amaqembu e-carbon functional;I-R iyiqembu elikwazi ukusebenzisa amanzi, okuhlanganisa i-OMe, i-OEt, njll.
Amaqembu asebenzayo athwelwe ngo-X athambekele ekuphenduleni ngamaqembu asebenzayo kuma-polymers ephilayo, njenge-OH, NH2, COOH, njll., ngaleyo ndlela axhuma i-silane nama-polymers wemvelo;Uma iqembu elisebenzayo lenziwa i-hydrolyzed, i-Si-R iguqulelwa ku-Si-OH futhi imikhiqizo ephumayo efana ne-MeOH, i-EtOH, njll.I-Si OH ingabhekana nokusabela kokufiphala nokuphelelwa amanzi emzimbeni nge-Si OH kwamanye ama-molecule noma i-Si OH ebusweni be-substrate ephathwayo ukuze yakhe amabhondi e-Si O-Si, futhi iphinde iphendule nama-oxide athile ukuze yakhe ibhondi ye-Si O ezinzile, ivumelesilaneukuxhuma ngezinto ezingaphili noma zensimbi.
Okuvamileama-silane coupling agentszihlanganisa:
I-silane equkethe isulfure: bis – [3- (triethoxysilicon) propyl] – tetrasulfide, bis – [3- (triethoxysilicon) propyl] – disulfide
I-Aminosilane: y-aminopropyltriethoxysilane, NB – (aminoethyl) – v-aminopropyltrimethoxysilane
I-Vinylsilane: Vinyltriethoxysilane, Vinyltrimethoxysilane
