I-Silane coupling agents luhlobo lwe-organic silicon compounds equlethe iipropathi ezimbini zeekhemikhali ezahlukeneyo kwi-molecule, ezisetyenziselwa ukuphucula amandla okwenene okudibanisa phakathi kweepolymers kunye ne-inorganic materials. Oku kunokubhekisa ekwandeni kokunamathela kokwenyani, kunye nokuphuculwa kokumanzi, iipropathi zerheological, kunye nezinye iipropathi zokusebenza. Iiarhente zokudityaniswa zinokuba nempembelelo yokuguqula indawo yojongano ukuze kuphuculwe umaleko womda phakathi kwezigaba eziphilayo kunye ne-inorganic.
Ngoko ke,i-silane coupling agentszisetyenziswa kakhulu kumashishini afana nokuncamathelisa, iingubo kunye nee-inki, irabha, ukuphosa, i-fiberglass, iintambo, amalaphu, iiplastiki, izihluzi kunye nonyango lwangaphezulu.
Imveliso yayo yeklastiki inokumelwa yi-formula jikelele ye-XSiR3, apho i-X i-non-hydrolytic group, kubandakanywa amaqela e-alkenyl (ikakhulukazi i-Vi) kunye namaqela e-hydrocarbon anamaqela asebenzayo afana ne-CI kunye ne-NH2 ekupheleni, oko kukuthi amaqela asebenzayo ekhabhoni; R liqela le-hydrolyzable, kuquka i-OMe, i-OEt, njl.
Amaqela asebenzayo athathwe kwi-X ajwayele ukusabela kunye namaqela asebenzayo kwiipolymer eziphilayo, ezifana ne-OH, NH2, COOH, njl., ngaloo ndlela idibanisa i-silane kunye neepolymer eziphilayo; Xa iqela elisebenzayo lifakwe i-hydrolyzed, i-Si-R iguqulwa ibe yi-Si-OH kunye neemveliso ezifana ne-MeOH, i-EtOH, njl. I-Si OH inokungena kwi-condensation kunye ne-dehydration reactions kunye ne-Si OH kwezinye iimolekyuli okanye i-Si OH kumphezulu we-substrate ephathwayo ukwenza iibhondi ze-Si O-Si, kwaye ziphinde ziphendule ngee-oxides ezithile zenze iibhondi ze-Si O ezizinzileyo, ezivumela.silaneukudibanisa nezinto ezingaphiliyo okanye zetsimbi.
