Silicone sealant poʻo le faʻapipiʻi o se mea mamana, fetuutuunai oloa e mafai ona faʻaaogaina i le tele o talosaga eseese. E ui lava e le malosi le fa'amaufa'ailoga silikoni e pei o nisi fa'amaufa'ailoga po'o mea fa'apipi'i, e tumau pea ona fetu'una'i le fa'amaufa'ailoga silikoni, tusa lava pe ua uma ona mago pefaamaloloina. E mafai fo'i e le fa'amaufa'ailoga silisiona ona tatalia le maualuga o le vevela, ma fa'apena mo fa'aoga o lo'o mafatia i le maualuga o le vevela, pei o luga ole afi afi.
Fa'amālōlō fa'amaufa'ailoga silikoni fa'aalia le lelei tele o le tau, fa'atupuina le matua, fa'afefe UV, osone, maualuga ma le maualalo o le vevela, tete'e o le vibration, le susu, ma le fa'afefe vai; o le mea lea, o ana faʻaoga e matua lautele lava. I le 1990s, e masani ona faʻaaogaina mo le faʻapipiʻiina ma le faʻamaufaʻailogaina i totonu o fale tioata, o lea e masani ona taʻua o le "faʻapipiʻi tioata."

Ata agavale: Fa'apipi'i pa'u o fa'amaufa'ailoga silikoni
Silicone sealant e masani ona faʻavae i luga ole 107(hydroxy-terminated polydimethylsiloxane), ma e aofia ai mea e pei o polymers maualuga-molecular-weight, plasticizers, fillers, cross-linking agents, coupling agents, catalysts, etc. Faʻapipiʻi masani e aofia ai le silicone. suauu, suauu paʻepaʻe, ma isi mea faʻapipiʻi masani e aofia ai le nano-activated calcium carbonate, mamafa calcium carbonate, ultrafine calcium carbonate, silica fumed, ma isi mea.
Silicone sealants e sau i ituaiga eseese.
E tusa ai ma le ituaiga o teuina, e vaevaeina i: lua (tele) vaega ma le tasi vaega.
E lua (tele) vaega o lona uiga o le silicone sealant e vaevaeina i ni vaega se lua (pe sili atu ma le lua) vaega A ma le B, soʻo se tasi vaega e le mafai ona faʻamalolo, ae a maeʻa ona faʻafefiloi vaega e lua (pe sili atu ma le lua), o le a latou. fa'atupuina feso'ota'iga feso'ota'iga fa'amalologa e fai ai elastomers.
O le paluga e tatau ona faia vave aʻo leʻi faʻaaogaina, lea e fai ai lenei ituaiga o faʻamaufaʻailoga silikoni e faigata ona faʻaoga.
Silicone sealant e mafai foi ona sau o se oloa e tasi, e aunoa ma se faʻafefiloi e manaʻomia. E ta'ua se tasi ituaiga o fa'amaufa'ailoga silicone tasi oloaVulcanizing Temperature Room(RTV). O lenei ituaiga o faʻamaufaʻailoga e amata ona fofo i le taimi lava e faʻaalia ai i le ea - pe, sili atu, o le susu i le ea. O le mea lea, e tatau ona e galue vave pe a faʻaaoga le RTV silicone sealant.
E mafai ona vaevaeina sealant silicone tasi-vaega i: ituaiga deacidification, ituaiga dealcoholization, ituaiga deketoxime, ituaiga deacetone, ituaiga deamidation, ituaiga dehydroxylamine, ma isi e tusa ai ma sui sooupu crosslinking eseese (po o molelaiti laiti gaosia i le taimi o faamalologa) faaaogaina. Faatasi ai ma i latou, ituaiga deacidification, ituaiga dealcoholization ma ituaiga deketoxime e masani ona faʻaaogaina i le maketi.
Deacidification ituaiga o le methyl triacetoxysilane (poʻo le ethyl triacetoxysilane, propyl triacetoxysilane, ma isi) e fai ma sui faʻafesoʻotaʻi, lea e maua ai le acetic acid i le taimi o togafitiga, e masani ona taʻua o le "acid kelu". O ona tulaga lelei o: malosi lelei ma manino, vave faʻamalolo vave. O mea le lelei o: faʻafefe o le acetic acid manogi, pala o metala.
O le tu'aiga tu'aiga o le methyl trimethoxysilane (po'o le vinyl trimethoxysilane, ma isi) e fai ma sui fa'afeso'ota'i, o lona fa'amalologa e maua mai ai le methanol, e masani ona ta'ua o le "kelu ituaiga ava". O ona tulaga lelei: puipuiga o le siosiomaga, e le corrosive. Leaga: fa'agesegese le fa'amalolo vave, fa'apolopolo le ola e fai si leaga.
Deketo oxime type o le methyl tributyl ketone oxime silane (poʻo le vinyl tributyl ketone oxime silane, ma isi) e fai ma sui faʻafesoʻotaʻi, e maua ai le butanone oxime i le taimi o togafitiga, e masani ona taʻua o le "oxime type glue". O ona tulaga lelei e: leai se manogi tele, pipii lelei i mea eseese. Le lelei: pala o kopa.
E tusa ai ma le faʻaogaina o oloa ua vaevaeina i: faʻamaufaʻailoga faʻapipiʻi, faʻamaufaʻailoga tau, faʻamaufaʻailoga faitotoʻa ma faʻamalama, faʻamau faʻamaufaʻailoga, faʻamaufaʻailoga afi, faʻamaufaʻailoga faʻafefe, faʻamaufaʻailoga maualuga.
E tusa ai ma le lanu o le oloa i togi: lanu masani uliuli, porcelain paepae, manino, lanu efuefu siliva 4 ituaiga, isi lanu e mafai ona tatou faia e tusa ai ma manaoga o tagata e faaaogāina auaunaga toning.
O lo'o i ai le tele o isi, sili atu fa'atekinolosi ituaiga fa'amaufa'ailoga silikoni. Tasi ituaiga, ua ta'uamaaleale mamafafa'amaufa'ailoga silikoni, e fa'amaumau tumau ma pipi'i ma le fa'amalosi ma'oti - i se isi fa'aupuga, e ui lava e "pi'i" i taimi uma, e le pipii pe a na'o se mea e pulumu pe fa'asaga i ai. O le isi ituaiga ua ta'uaUV or fa'amaloloina fa'avevelafa'amaufa'ailoga silikoni, ma fa'aogaina le malamalama ultraviolet e fa'amalolo ai le fa'amau. Mulimuli ane,thermosetsilicone sealant e manaʻomia le faʻaalia i le vevela ina ia mafai ai ona fofo.
Silicone sealant e mafai ona faʻaaogaina i le tele o talosaga. O lenei ituaiga fa'amaufa'ailoga e masani ona fa'aaogaina i ta'avale ma fa'aoga fa'atatau, e pei o se fesoasoani mo le fa'amauina o se afi, fa'atasi pe leai fo'i gaskets. Ona o lona sili atu ona fetuutuunai, o le sealant o se filifiliga lelei foi mo le tele o mea e fiafia i ai po o galuega taulima.
