Izakhiwo Ezibonakalayo

Luwuketshezi oluphuzi olucwebezelayo olukhanyayo olunephunga elincane lotshwala futhi luncibilika kalula kutshwala, i-acetone, i-benzene, i-toluene njll. Aluncibiliki emanzini. Lungancibilika emanzini uma luthinta amanzi noma umswakama. Amandla adonsela phansi angu-1.08g/ml.

Imininingwane

α γ2: γ-chloropropyltriethoxy silane. β: ikakhulukazi iqukethe ukungcola kwe-silane.

Ibanga Lohlelo Lokusebenza

I-HP-669 isetshenziswa ngempumelelo embonini yerabha njenge-ejenti yokuxhumanisa i-poly sulfur silane esebenza kabili.
I-HP-669 ingasetshenziswa ohlelweni lwerabha oluhlanganisiwe olunezigcwalisi ezifana ne-silica, i-fiberglass, i-talc powder, i-mica powder kanye nobumba njenge-ejenti yokuqinisa. Ingathuthukisa izakhiwo zokuqinisa zezigcwalisi kanye nezakhiwo zokumelana nokuklwebheka kwerabha.
Ifanele ukusetshenziswa njengesengezo serabha—i-ejenti yokuvuselela kanye ne-activator kuma-polymers afana ne-NR, i-IR, i-SBR, i-BR, i-NBR kanye ne-EPDM.
Enkambisweni ye-vulcanization, izinga lokuxhumanisa le-poly-sulfur alkyl lifana nezinga le-deoxidizing le-sulfur, ngakho-ke lisebenza ukumelana ne-deoxidization ye-vulcanization, bese lithuthukisa izakhiwo zokugoba eziguqukayo njengokwakheka kokushisa kanye nokwanda kwama-crack. Ama-athomu amane e-sulfur angasebenza njenge-activator ye-vulcanization.
Ezimweni eziguquguqukayo nezinganyakazi, isetshenziselwa ukukhiqiza le mikhiqizo yerabha: ithayi, ipayipi, irabha yokugoqa, ibhande, ikhebula, izicathulo kanye nemikhiqizo yokusungula imishini. Ingathuthukisa ukumelana nokuklwebheka, ukumelana nokusika kanye nokumelana nengcindezi, inciphise ukulahlekelwa yi-hysteresis kanye ne-hygroscopicity, ithuthukise izakhiwo zemishini nezokunamathela, futhi ikhulise ukusebenza kokuguga kokushisa, i-modulus kanye nokuphila kwe-flex.
Engeza i-ejenti yokuhlanganisa i-sulfur-silane embonini yamathayi enjoloba, ayigcini nje ngokunciphisa ingozi yokubhoboka njengoba izinga lokushisa liphezulu kakhulu uma ugijima emgwaqweni ohamba ngesivinini esikhulu noma isikhathi eside, kodwa futhi inciphisa ukumelana nokugoqa kwethayi, bese inciphisa ukusetshenziswa kukaphethiloli, inani lokukhishwa kwe-CO2 ukuze kuhambisane nokuvikelwa kwemvelo kokunciphisa ikhabhoni.
