A) Sui so'o fa'atasi:
Galuega fa'aletinoalkoxysilanee fa'aoga e fa'aluaina polymers fa'aola ma mea e le fa'a-organic, ma o le uiga masani o lenei talosaga o le fa'amalosia.Mo se faʻataʻitaʻiga, alava tioata ma minerale faʻatumu faʻafefiloi ma palasitika ma paʻu.E fa'aogaina fa'atasi ma le thermosetting ma le thermoplastic system.O mea e faʻatumu ai minerale, e pei o le paʻepaʻe carbon black, talc, Wollastonite, omea ma isi mea, e faʻaopoopo saʻo i le faʻafefiloi o faʻagasologa poʻo le muaʻi togafitia masilanepo'o le fa'agasologa tu'ufa'atasi.
E ala i le fa'aogaina o le silane fa'akomepiuta i luga ole hydrophilic, non Organic reaction fillers, o le mineral surface e fa'afoliga ma lipophilic.Fa'aaogāga alava tioata e aofia ai le tino o le ta'avale, va'a, ta'ele, laupapa fa'asalalau lolomi, antenna Televise satelite, paipa palasitika ma pusa, ma isi.
O faiga e fa'atumu ai minerale e aofia ai le polypropylene fa'amalosia, palasitika fa'apipi'i pa'epa'e kaponi pa'epa'e, uili olo fa'ameamea kasa, sima polymer fa'atumu, oneone fa'atumu le resini, ma uaea EPDM ua fa'atumuina ele, fa'apea fo'i le pa'u e tumu i le omea ma le pa'u pa'epa'e kaponi pa'epa'e mo ta'avale. pa'u, seevae seevae, mea fa'ainisinia, ma isi mea fa'aoga.
B) Fa'aliga fa'apipi'i
Pe a faʻaaogaina e fai ma mea faʻapipiʻi ma faʻamuamua mo le faʻapipiʻiina o vali, vaitusi, ufiufi, faʻapipiʻi, ma faʻamaufaʻailoga,silaneso'o fa'apipi'i e fa'aoso fa'apipi'i.A faʻaaogaina e avea o se faʻaopoopoga lautele, e manaʻomia e le silane le faʻafeiloaʻi i le va o le faʻapipiʻi ma le mea e togafitia ina ia aoga.A fa'aaogaina e fai ma fa'amata, e mana'omia le fa'aogaina o so'o fa'apipi'i silane mo mea e le fa'aogaina a'o le'i fa'apipi'iina le oloa.
I lenei tulaga, o loʻo i ai le silane i se tulaga lelei e galue ai o se faʻaleleia faʻapipiʻi (i totonu o le vaega faʻaoga).I le fa'aoga sa'o o le silane so'o fa'apipi'i, e o'o lava i tulaga faigata o le si'osi'omaga, o le vaitusi pipi'i, vali, fa'apipi'i, po'o le fa'amaufa'ailoga e mafai ona fa'atumauina le pipii.
C) Vai sulfur, faʻasalalau
Siloxanes fa'atasi ai ma vaega fa'aletino fa'apipi'i e fa'apipi'i i fa'amea kasa e mafai ona tu'uina atu i luga o le vai fa'atasi ai ma uiga tutusa o le hydrophobic, ma o lo'o fa'aaogaina e avea ma vaila'au fa'ato'aga umi i fale, alalaupapa, ma fa'ato'aga.O lo'o fa'aogaina fo'i i pa'u pa'u fa'ato'aga hydrophobic ina ia mafai ai ona tafe sa'oloto ma ta'ape gofie i polymers ma vai.
D) Sui so'otaga
Ole alkoxysilane galue fa'aletino e mafai ona tali fa'atasi ma polymers fa'aola, fa'apipi'i vaega trialkoxyalkane ile filifili autu ole polymer.Ona mafai lea e le silane ona tali atu i le ausa vai e faʻafesoʻotaʻi ai le silane, ma fausia ai se fausaga siloxane tolu-dimensional mautu.O lenei masini e mafai ona faʻaogaina e faʻafesoʻotaʻi ai palasitika, polyethylene, ma isi resini faʻaola, e pei ole resini acrylic ma polyurethane paʻu, e faʻaleleia ai le tumau ma le faʻafefe o vali, faʻapipiʻi, ma faʻapipiʻi.
PSI-520 silane coupling agent o loʻo faʻaaogaina mo togafitiga faʻasalalau faʻasolosolo o mea faʻapipiʻi e pei o le MH / AH, kaolin, talc powder, ma isi. E fetaui lelei foi mo le MH / AH togafitiga faʻale-aganuʻu ma le faʻaogaina i mea e leai se mea uaea halogen.O le togafitiga o mea faʻapipiʻi paʻu o loʻo i ai le hydrophobicity o le 98%, ma o le faʻafesoʻotaʻi vai i luga o le paʻu oona e ≥ 110º.O le paʻu faʻapitoa e mafai ona faʻasalalau tutusa i polymers organic e pei o resin, palasitika, ma paʻu, faʻatasi ai ma uiga o le faʻaleleia o le faʻasalalauga faʻatinoga o faʻatumu;Fa'ateleina le tau o le okesene fa'atapula'aina index (LOI);Faʻateleina o le hydrophobicity o le faʻatumu e mafai foi ona faʻaleleia mea tau eletise (dielectric constant tan, tele eletise ρ D) A maeʻa ona faʻafeiloaʻi vai;Faʻateleina le aofaʻi o mea faʻapipiʻi faʻaopoopo, aʻo iai foʻi le malosi maualuga ma le faʻalauteleina i le malepe;Faʻaleleia le vevela vevela ma faʻaleleia le faʻatinoga
