I-silicone sealant yenye yezona zinto zokuncamathelisa ezisebenziseka lula kunye nezixhobo zokutywina kulwakhiwo lwanamhlanje kunye nokuveliswa. Ukuguquguquka kwayo, ubomi bayo obude, kunye nokumelana nemozulu kunye nobushushu obugqithisileyo kwenza ukuba ibe lukhetho lokuqala lweengcali kwihlabathi liphela.
Nangona kunjalo, ukukhethauhlobo olufanelekileyo lwe-silicone sealantAkulula njengoko kubonakala. Ukukhetha gwenxa kunokukhokelela ekungabambeki kakuhle, ukuvuza, ukuqhekeka, okanye ukuphinda kusetyenziswe imali eninzi. Esi sikhokelo sibonelela ngesikhokelo sokulungisa izinto.isakhelo sobungcali, ngokusekelwe kwimigangatho yamazwe ngamazwe (ASTM, ISO, GB), ukukunceda ukhethe isitywina se-silicone esifanelekileyo kwiprojekthi yakho.
1. Tshatisa iSealant neSubstrate (Izinto ezisemgangathweni)
Izitywini zesilicone azihambelani ngokupheleleyo nazo zonke izinto ezisetyenziswayo. Indlela engalunganga yokwenza izinto inokubangela ukugqwala okanye ukungaphumeleli kokubopha.
-Iglasi kunye neGlazing
--Sebenzisai-silicone yonyango olungathathi calaIifomyula ze-acetoxy (ezine-asidi) zinokudla izihlanganisi zesinyithi kwiinkqubo zeglasi.
--Umzekelo: Iiprojekthi zodonga lwamakhethini ezifanaIsitishi sikaloliwe saseMzantsi eBeijingi-silicone engasetyenziswanga neutral ukuqinisekisa ukuba ihlala ixesha elide kangangeminyaka engama-20 nangaphezulu.
Iiphaneli ze-Aluminiyam kunye neMetal
--Kucetyiswa ukuba ii-silicone zesakhiwo ezicocayo nezingathathi cala zithintele ukubola okanye ukubola.
--ASTM C1184 icacisa iimfuno zokusebenza kwezixhobo zokutywina iiglasi zesakhiwo.
-Ikhonkrithi, Amatye, kunye noBugcisa
--Ii-substrates ezinemingxuma zifuna ii-primer ngaphambi kokuba zifake i-silicone ukuthintela ukufunxwa kunye nokunamathela okubuthathaka.
--I-silicone engathathi cala enekhono eliphezulu lokushukuma (±50%) ikhethwa kakhulu kwiindawo zokwandisa amalungu.
-Iiplastiki (iPVC, iPolycarbonate, iAcrylic)
--Ayizizo zonke ii-silicone ezinamathela kakuhle. Uvavanyo lokuhambelana kubalulekile kuba ezinye iiplastiki zikhupha iioyile ezithintela ukubola.
--Kwiindawo zokuvala ze-elektroniki, ii-silicone ze-RTV (i-Room Temperature Vulcanizing) zixhaphakile.
Ingcebiso yobungcali:Soloko ucelaIphepha leDatha yoBugcisa (i-TDS)kumthengisi wakho kwaye ujonge ii-substrates ezicetyiswayo. Kwiiprojekthi ezinkulu, yenza uvavanyo lokuhambelana ngaphambi kokusetyenziswa ngobuninzi.
2. Ukusetyenziswa Kwangaphakathi vs. Kwangaphandle
Iindawo ezahlukeneyo zifuna iindlela ezahlukeneyo zokwenziwa.
1. Izicelo zangaphakathi
--Ii-silicone sealants zococeko ezineizongezo ezichasene nefunguszezona zilungele iikhitshi, amagumbi okuhlambela, kunye nemibhobho ye-HVAC.
--Zithintela ukukhula kwesikhunta esimnyama kwiindawo ezifumileyo kwaye ziyavavanywa ngokwe-ISO 846 ukuze zifumane ukumelana neentsholongwane.
--Iifomyula ze-VOC eziphantsi (i-volatile organic compound) ziyacetyiswa ukuze zihlangabezane nemigangatho yezakhiwo eziluhlaza zanamhlanje (i-LEED, i-BREEAM).
2. Izicelo Zangaphandle
--Ii-sealants kufuneka zixhathiseImitha ye-UV, i-ozone, ukuguquguquka kobushushu, kunye nokuvezwa yimvula.
--I-silicone yokulungisa engathathi cala enomthamo ophezulu wobude (ukuya kuthi ga kwi-400%) iqinisekisa ukuba isitywino sihlala singaguquki xa sisandiswa ngobushushu.
--Umzekelo:Ikomkhulu leCCTV eBeijingi-silicone sealant esebenza kakuhle iyadingeka kwiindawo zokudibanisa ubuso ezichatshazelwe kubusika obuyi-20°C kunye nehlobo eliyi-+40°C.
3. Izinto ezibangela uxinezeleko lwendalo kunye noomatshini
Ngaphambi kokukhetha i-sealant, jongaiimeko zoxinzeleloiprojekthi yakho iya kujongana:
1) .Ukumelana nobushushu
--Iisilicone zeenjongo eziqhelekileyo: -40°C ukuya ku +150°C
--Iisilicone ezishushu kakhulu: ukuya kuthi ga kwi-+300°C ukuvezwa rhoqo
--Umzekelo: Iigasket zezithuthi zisebenzisa i-silicone ebomvu enobushushu obuphezulu ukumelana nobushushu benjini.
2) .Ukufuma kunye nokufuma
--Iigumbi zokuhlambela neekhitshi: sebenzisa i-silicone yococeko ene-mildew inhibitors.
--Iibhulorho zangaphandle kunye neetonela: ukumelana nokuntywiliselwa emanzini kubalulekile.
3) .Ubuchule bokuHamba
--Ichazwe yi-ASTM C719 (intshukumo yesitywina).
--Amalungu okwandisa kwi-façades: Kufuneka intshukumo eyi-±50%.
--Izitywini ezisebenza kancinci (±12.5%) zilungele kuphela izikhewu ezincinci.
4. Izicelo zeSakhiwo vs. ezingezizo ezeSakhiwo
1) .Iitywina zeSilicone zoLwakhiwo
--Isetyenziswa kwiglasi yodonga lwekhethini kunye ne-bonding ethwala umthwalo.
--Kufuneka ithobele i-ASTM C1184 okanye i-GB 16776 (eTshayina).
--Ifuna ukulungiswa komphezulu ngokuchanekileyo, uyilo lokudibanisa, kunye nolawulo lomgangatho ngexesha lokufakwa.
2) .IiSilicone zeNjongo Jikelele
--Ixabiso layo liphantsi, kulula ukuyifaka, kwaye ifanelekile ekulungiseni izinto zasekhaya nasekuvaleni izinto ezingabalulekanga.
--Ixesha lobomi lihlala lifutshane (iminyaka emi-5–10) xa lithelekiswa neesilicones zesakhiwo (iminyaka engama-20–30).
5. Iziqinisekiso kunye neMigangatho yoMgangatho
Abathengi abaziingcali kufuneka baqinisekise rhoqo izatifikethi:
--ISO 9001 kunye ne-ISO 14001– Iinkqubo zolawulo lomgangatho nokusingqongileyo.
--Imigangatho yeASTM– C920 (i-elastomeric joint sealants), C1184 (i-structural glazing).
--Imigangatho yeGB (eTshayina)– GB/T 14683 (izinto zokuvala izakhiwo).
--Uphawu lwe-CE (eYurophu)– Iqinisekisa ukuthotyelwa kwemigangatho yokhuseleko kunye nokuqina yaseYurophu.
Ezi ziqinisekiso zinciphisa iingozi zeprojekthi kwaye ziqinisekisa ukuthotyelwa kweemfuno zikarhulumente nezemizi-mveliso.
6. Ukulula kokusetyenziswa
I-Silicone yeCandelo elinye (i-RTV)
--Iikhatriji okanye iisoseji ezilungele ukusetyenziswa.
--Inyanga xa ifumile, ngesiqhelo ngaphakathi kweeyure ezingama-24–48.
--Ilungele usetyenziso lwesiza apho isantya kunye nokulula kubalulekile.
I-Silicone enamacandelo amabini
--Ifuna ukuxuba, kodwa inyangeka ngokukhawuleza nangokungaguquguqukiyo.
--Ikhethwayoiglasi yefektrikwayeimigca yokuhlanganisa yemizi-mveliso.
--Umzekelo: Isetyenziswa kwimigca yokuvelisa iindonga zamakhethini ezenzekelayo ukuqinisekisa ukuphiliswa rhoqo.
7. Ukusebenza kweendleko xa kuthelekiswa nomjikelo wobomi
Kuyathandeka ukukhetha i-sealant enexabiso eliphantsi, kodwa iindleko zomjikelo wobomi zibaluleke ngakumbi.
--Isitywini esingabizi kakhulu: ukunamathela okuncinci, ukutshintsha kombala, ukuqhekeka kwisithuba seminyaka emi-3-5.
--I-silicone yesakhiwo sePremium: Iminyaka engama-20–30 yobomi benkonzo, iindleko zokulungisa eziphantsi, kunye ne-ROI engcono yexesha elide.
--Kwiiprojekthi ezinkulu zokwakha,iindleko zesitywina zingaphantsi kwe-1% yebhajethi iyonke yefaçade, kodwa ukungasebenzi kakuhle kwe-sealant kunokubangela ukuba kulungiswe izigidi zabantu.
