I-Silane coupling agents luhlobo lwee-organic silicon compounds eziqulethe 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 zide ziphendule ngee-oxides ezithile zenze iibhondi ze-Si O ezizinzileyo, ezivumela.silaneukudibanisa nezinto ezingaphiliyo okanye zetsimbi.
