Yiziphi izinhlelo zokusebenza ze-silane?

Izindaba

A) I-ejenti yokuhlanganisa:
Ukusebenza kwe-organici-alkoxysilaneisetshenziselwa ukuhlanganisa ama-polymer aphilayo nezinto ezingaphili, futhi isici esijwayelekile salolu hlelo lokusebenza ukuqinisa. Isibonelo, i-glass fibre kanye ne-mineral fillers exutshwe nepulasitiki nerabha. Zisetshenziswa ngokuhambisana ne-thermosetting kanye ne-thermoplastic systems. Izigcwalisi zamaminerali, njengekhabhoni emhlophe emnyama, i-talc, i-Wollastonite, ubumba nezinye izinto, zengezwa ngqo kwinqubo yokuxuba noma ziphathwe ngaphambilisilanenoma kunqubo eyinhlanganisela.
Ngokusebenzisa i-organic functional silane kuma-hydrophilic, ama-non-Organic reaction fillers, i-mineral surface iqala ukusebenza futhi ibe ne-lipophilic. Izicelo ze-glass fiber zihlanganisa umzimba wemoto, umkhumbi, ishawa, ibhodi lesifunda eliphrintiwe, i-satellite Television antenna, ishubhu lepulasitiki nesiqukathi, nokunye.

silane
Izinhlelo zokugcwalisa amaminerali zifaka i-polypropylene eqinisiwe, amapulasitiki amhlophe agcwele ikhabhoni emnyama, amasondo okugaya e-silicon carbide, ukhonkolo ogcwele i-polymer ogcwele isihlabathi, izintambo zokulahla ezigcwele isihlabathi, izintambo nezintambo ze-EPDM ezigcwele ubumba, kanye nerabha egcwele isikhutha esimhlophe esigcwele izimoto. amathayi, amasoli ezicathulo, izinto zokwakha, nezinye izinto zokusebenza.
B) Umgqugquzeli we-Adhesive
Uma isetshenziswa njenge-adhesive kanye ne-primer yokubopha amapende, oyinki, okokunamathela, okunamathelisa kanye nama-sealants,silaneama-coupling agents angabagqugquzeli bokunamathela. Uma isetshenziswa njengesengezo sisonke, i-silane idinga ukuthuthela esixhumi esibonakalayo phakathi kokunamathelayo nokokusebenza okulashiwe ukuze ibe wusizo. Uma isetshenziswa njenge-primer, ama-agent okuhlanganisa ama-silane adinga ukusetshenziselwa izinto ezingaphili ngaphambi kokuba umkhiqizo uhlanganiswe.
Kulesi simo, i-silane isesimweni esihle sokusebenza njengesithuthukisi esihlanganisayo (endaweni yokusebenzelana). Ngokusebenzisa ngendlela efanele izinto ezihlanganisa i-silane, ngisho nasezimeni ezingezinhle zemvelo, uyinki onamathele, upende, into enamathelayo, noma isivalo singagcina ukunamathela.
C) Amanzi esibabule, dispersant
Ama-Siloxanes anamaqembu e-hydrophobic organic anamathiselwe kuma-athomu e-silicon anganikeza izindawo ze-hydrophilic ze-inorganic ezinezici ezifanayo ze-hydrophobic, futhi asetshenziswa njengama-ejenti ahlala isikhathi eside we-hydrophobic ekwakheni, ebhulohweni, nasekufakweni kwedekhi. Zibuye zisetshenziswe kuma-hydrophobic inorganic powders ukuzivumela ukuthi zigeleze ngokukhululeka futhi zihlakazeke kalula kuma-polymers we-organic kanye noketshezi.
D) I-Crosslinking agent
I-alkoxysilane esebenzayo ye-organic ingasabela nama-polymers ephilayo, ibophe amaqembu e-trialkoxyalkane ochungechungeni oluyinhloko lwe-polymer. I-silane ingabe isisabela ngomhwamuko wamanzi ukunqamula i-silane, yakhe isakhiwo se-siloxane esizinzile esinezinhlangothi ezintathu. Lo mshini ungasetshenziswa ukuxhumanisa amapulasitiki, i-polyethylene, nezinye izinhlaka zemvelo, njenge-acrylic resin nerabha ye-polyurethane, ukuthuthukisa ukuqina kanye nokungangeni kwamanzi kopende, okokunamathela, nezinamatheliso.
I-agent ye-PSI-520 ye-silane coupling isetshenziselwa ukwelashwa kwe-organic dispersion of fillers njenge-MH/AH, i-kaolin, i-talc powder, njll. Ibuye ifanelekele i-MH/AH yokwelashwa kwe-organic kanye nokusetshenziswa kwezinto zekhebula ezingenalo halogen. Ukwelashwa kwezinto zempushana ezingaphili kune-hydrophobicity engu-98%, kanti i-engeli yokuxhumana namanzi ebusweni bempushana yemvelo ingu-≥ 110 º. I-powder ye-inorganic ingahlakazwa ngokulinganayo kuma-polymers ephilayo njenge-resin, ipulasitiki, nerabha, enezici zokuthuthukisa ukusebenza kokuhlakazeka kwezigcwalisi; Khulisa inani le-oxygen limiting index (LOI); Ukwandisa i-hydrophobicity ye-filler kungase futhi kuthuthukise izakhiwo zikagesi (i-dielectric constant tan, ugesi omningi ρ D) Ngemva kokuhlangana namanzi; Khulisa inani lokugcwaliswa okungeziwe, kuyilapho futhi unamandla aphezulu okudonsa kanye nobude ngesikhathi sekhefu; Thuthukisa ukumelana nokushisa futhi uthuthukise ukusebenza
