Yintoni usetyenziso lwe-silane?

Iindaba

A) I-arhente yokudibanisa:
Ukusebenza kwe-Organicialkoxysilaneisetyenziselwa ukudibanisa iipholima eziphilayo kunye nemathiriyeli ye-inorganic, kwaye uphawu oluqhelekileyo lwesi sicelo kukuqinisa.Ngokomzekelo, i-fiber yeglasi kunye ne-mineral fillers exutywe neplastiki kunye nerabha.Zisetyenziswa ngokubambisana ne-thermosetting kunye ne-thermoplastic systems.Izihluzi zeminerali, ezifana nekhabhoni emhlophe emnyama, i-talc, i-Wollastonite, udongwe kunye nezinye izinto, zongezwa ngokuthe ngqo kwinkqubo yokuxuba okanye ukuphathwa kwangaphambili kunyesilaneokanye kwinkqubo edibeneyo.
Ngokusebenzisa i-organic functional silane kwi-hydrophilic, non Organic reaction fillers, umphezulu wezimbiwa uba reactive kwaye lipophilic.Ukusetyenziswa kwefiber yeglasi kubandakanya umzimba wemoto, inqanawa, ishawa, ibhodi yesekethe eprintiweyo, i-antenna yeTelevishini yesathelayithi, ityhubhu yeplastiki kunye nesitya, kunye nabanye.

silane
Iinkqubo zokuzalisa izimbiwa ziquka i-polypropylene eyomeleziweyo, iiplastiki ezibunjiweyo zekhabhoni ezimhlophe ezimhlophe, amavili e-silicon carbide okusila, ikhonkrithi egcwele i-polymer egcwele igranular, isanti ezaliswe yintlabathi yokuphosa, kunye neengcingo ze-EPDM ezizaliswe ngodongwe kunye neentambo, kunye nodongwe oluzaliswe yirabha egcwele i-carbon emnyama egcwele iimoto. amatayara, iisoli zezihlangu, imathiriyeli yoomatshini, kunye nezinye izinto ezisetyenziswayo.
B) Umgqugquzeli wokuncamathelisa
Xa isetyenziswa njengento yokuncamathelisa kunye neprimer yokudibanisa iipeyinti, ii-inki, iingubo, izinto zokuncamathelisa, kunye nezitywini,silaneii-agents ezidibanisayo ngabakhuthazi bokubambelela.Xa isetyenziswe njengesongezo ngokubanzi, i-silane idinga ukufuduka kwi-interface phakathi kwe-adhesive kunye nezinto eziphathwayo ukuze zibe luncedo.Xa isetyenziswa njenge-primer, ii-agent zokudibanisa i-silane kufuneka zisetyenziswe kwizinto ezingaphiliyo phambi kokuba imveliso ibotshwe.
Kule meko, i-silane ikwimeko efanelekileyo yokusebenza njengesixhasi sokubopha (kwindawo yojongano).Ngokusebenzisa ngokuchanekileyo i-silane coupling agents, naphantsi kweemeko ezirhabaxa zokusingqongileyo, i-inki encamatheleyo, ipeyinti, into encamathelayo, okanye into yokutywina inokugcina ukuncamathelisa.
C) Amanzi esulfure, dispersant
I-Siloxanes enamaqela e-hydrophobic organic adityaniswe kwi-athomu ye-silicon inokunika iindawo ze-hydrophilic ze-inorganic kunye neempawu ezifanayo ze-hydrophobic, kwaye zisetyenziswa njengeejenti ze-hydrophobic ezihlala ixesha elide ekwakheni, kwibhulorho, nakwi-deck applications.Zikwasetyenziswa kwi-hydrophobic inorganic powders ukuzivumela ukuba zihambe ngokukhululekileyo kwaye zisasazeke ngokulula kwiipolymer eziphilayo kunye nolwelo.
D) I-arhente edibanisayo
I-alkoxysilane esebenzayo ye-Organic inokusabela nge-polymers eziphilayo, ukubopha amaqela e-trialkoxyalkane kwikhonkco eliphambili le-polymer.I-silane inokusabela ngomphunga wamanzi ukunqumla i-silane, yenze ulwakhiwo oluzinzileyo lwe-siloxane enamacala amathathu.Lo matshini unokusetyenziselwa ukunqumla iiplastiki, i-polyethylene, kunye nezinye ii-resin eziphilayo, ezifana ne-acrylic resin kunye nerabha ye-polyurethane, ukomeleza ukuqina kunye nokungangeni kwamanzi kwepeyinti, iingubo kunye nokunamatheliswa.
I-agent ye-PSI-520 yokudibanisa i-silane isetyenziselwa unyango lwe-organic dispersion of fillers ezifana ne-MH / AH, i-kaolin, i-talc powder, njl.Unyango lwemathiriyeli yomgubo we-inorganic ine-hydrophobicity ye-98%, kwaye i-angle yoqhagamshelwano lwamanzi kumphezulu womgubo we-organic inorganic ngu ≥ 110 º.I-powder ye-inorganic inokusasazwa ngokufanayo kwiipolymer eziphilayo ezifana ne-resin, iplastiki, kunye ne-rubber, kunye neempawu zokuphucula ukusebenza kwe-dispersion of fillers;Ukwandisa ixabiso le-oxygen limiting index (LOI);Ukwandisa i-hydrophobicity ye-filler kunokuphucula iimpawu zombane (i-dielectric constant tan, umbane omkhulu ρ D) Emva kokudibana namanzi;Yandisa isixa sokugcwaliswa okongeziweyo, ngelixa ukwanawo amandla aphezulu kunye nobude ngexesha lekhefu;Ukuphucula ukumelana nobushushu kunye nokuphucula ukusebenza
