Izinto zokuvala ze-siliconezisetshenziswa kabanzi ekwakheni, ekufakeni amaglasi, nasekulungiseni izindlu ngenxa yezizathu zazo.ukuguquguquka, ukumelana nesimo sezulu, kanye nokuphila isikhathi esideKodwa ngisho ne-silicone sealant engcono kakhulu ingahluleka uma isetshenziswe ngendlela engafanele noma ngaphansi kwezimo ezingalungile.
Ngezansi, sichaza izinkinga ezivame kakhulu ngama-silicone sealant, izimbangela zazo, kanye nezixazululo zesinyathelo ngesinyathelo zokuzilungisa.
1. Ukunamathela Okubi (Isivali Asinamatheli)
Izimpawu:I-sealant iyahlubuka, ihlukane, noma ayibophi ebusweni.
Izimbangela:
-
--Izinsika ezingcolile, ezinothuli, noma ezinamafutha
-
--Umswakama ebusweni ngesikhathi sokufaka
-
--I-substrate engahambisani (isb., i-polyethylene, i-PTFE, noma izinkuni ezinamafutha)
-
--Isivali esiphelelwe yisikhathi noma esisezingeni eliphansi
Indlela Yokulungisa:
-
1. Susa ngokuphelele isivalo esiphukile ngesikrufu noma ngesisusi se-sealant.
-
2.Hlanza i-substrate nge-solvent (i-IPA noma i-acetone) ukuze ususe amafutha nothuli.
-
3.Sebenzisa i-i-primeruma kuhlanganiswa nezinto ezinezimbobo ezifana nokhonkolo noma itshe lemvelo (Ukuhlolwa Kokunamathela kwe-ASTM C794).
- 4. Phinda ufake ubuhlalu obusha be-aisivalo se-silicone esingathathi hlangothiukuze kube nokunamathela okungcono
2. Ukubhamuka noma Ukuphelelwa Yisivalo Esivalweni
Izimpawu:Amapokhethi omoya, amabhamuza, noma amabala angenalutho avela ngaphakathi kwe-sealant evuvukile.
Izimbangela:
-
--Umoya ovalelekile ngesikhathi sokufaka
-
--Umswakama owedlulele emalungeni (ikakhulukazi ezindaweni ezinomswakama)
-
--Isivalo sifakwe kakhulu ngesikhathi esisodwa
Indlela Yokulungisa:
-
--Sika bese ususa izingxenye ezinamabhamuza.
-
--Qiniseka ukuthi i-substrate yomile ngokuphelele ngaphambi kokufaka kabusha.
-
--Faka i-sealant ngezingqimba uma ugcwalisa amalunga ajulile, usebenzisaizinduku zokusekelalapho kudingeka khona (Umhlahlandlela Wokutywina Ama-Dow Construction).
- --Khetha ibanga lochwephesheisivalo se-silicone esakhiwe ngesakhiwoukuze kube nokuzinza.
3. Ukuncishiswa noma ukuqhekeka kwesivalo
Izimpawu:I-sealant iyancipha, idonseleke emaphethelweni, noma idale imifantu.
Izimbangela:
-
--Ukusebenzisa umkhiqizo osezingeni eliphansi noma osekelwe ku-solvent olahlekelwa yivolumu lapho uphola
-
--Ukufaka i-sealant emazingeni okushisa aphezulu kakhulu
-
--Ukwakheka kwamalunga okungalungile (kuncane kakhulu, akukho ukuvumela ukunyakaza)
Indlela Yokulungisa:
-
--Susa ubuhlalu obunephutha bese uphinda ufakai-silicone sealant yokwelapha engathathi hlangothi encipha kancane.
-
--Landela umklamo ohlanganisiwe onconyiwe ngamunyeIzindinganiso ze-ISO 11600:2002
- --Faka ngaphakathi kwebanga lokushisa elinconywe ngumenzi (ngokuvamile 5–40°C).
4. Ukukhula Kwesikhunta Nokukhunta
Izimpawu:Kuvela amabala amnyama noma amnyama, ikakhulukazi ezindlini zangasese nasemakhishini.
Izimbangela:
-
--Ukuchayeka isikhathi eside emswakama kanye nomswakama
-
--Ukuntuleka komoya endaweni
-
--Ukusebenzisa i-silicone engahlanzekile ezindaweni ezimanzi
Indlela Yokulungisa:
-
--Sika ngokuphelele isivalo esinobuthi (ukuhlanza kukodwa akusebenzi).
-
--Hlanza indawo nge-bleach exutshwe amanzi noma umshini wokuhlanza isikhunta.
- --Faka isicelo kabushaisivalo se-silicone esihlanzekilengezithasiselo zokubulala ukhunta.
- --Thuthukisa umoya ukuze uvimbele ukukhula kwesikhathi esizayo.
5. Isivali Asipholi Noma Sihlala Sinamathela
Izimpawu:I-silicone ihlala ithambile, inamathele, noma ayisoze yaqina.
Izimbangela:
-
--Umkhiqizo ophelelwe yisikhathi noma isitoreji esingafanele
-
--Indawo yokulungisa engahambisani (umswakama ophansi wama-silicone e-RTV ayingxenye eyodwa)
-
Iphutha lokuxuba (kuma-silicone anezingxenye ezimbili)
Indlela Yokulungisa:
-
-- Susa i-silicone engakapheki ngokuphelele.
-
--Sebenzisa umkhiqizo omusha ogcinwe endaweni epholile, eyomile.
-
--Kuma-silicone aqeda umswakama, qinisekisa amazinga afanele omswakama (40–70% RH).
-
--Kwimikhiqizo enezingxenye ezimbili, landela izilinganiso zokuxuba ngokunembile (Umhlahlandlela Wokwelapha I-Sealant – BSI).
6. Isivali Esikhipha Amalunga (Ukwehluleka Kwamalunga)
Izimpawu:Kuvuleka izikhala phakathi kwe-sealant kanye ne-substrate, okushiya i-joint ingavalwanga.
Izimbangela:
-
--Ukunyakaza kwe-substrate ngale kwebanga lokuguquguquka kwe-sealant
-
--Ukwakheka kwamalunga okungalungile (okujulile kakhulu noma okungajulile kakhulu)
-
--Akusebenzi i-backer rod noma i-bond breaker tape
Indlela Yokulungisa:
--Yakha kabusha ijoyinti ngokushoIzindinganiso ze-ASTM C920-18(2024)
--Sebenzisa i-sealant enekhono lokunyakaza elifanele (+/- 25% noma ngaphezulu).
--Njalo faka i-sealant phezu kwenduku yokusekela noma i-bond breaker ukuze uvimbele ukunamathelana okunezinhlangothi ezintathu.
Ithebula Lokuxazulula Izinkinga Ngokushesha
| Inkinga | Imbangela Eyinhloko | Lungisa |
|---|---|---|
| Ukunamathela okubi | Indawo engcolile / ukungahambelani | Hlanza, faka kabusha, phinda ufake |
| Ukubhabhula/ukungabi nalutho | Umswakama / ukuvaleka komoya | Yomisa, phinda ufake izingqimba ezincane |
| Ukushwabana/ukuqhekeka | Idizayini ye-sealant esezingeni eliphansi / i-joint engalungile | Sebenzisa ikhambi elingathathi hlangothi, dala kabusha ijoyinti |
| Ukukhula kwesikhunta | Isivali esingenakho ukungcola / umswakama | Shintsha nge-silicone yenhlanzeko |
| Akupholi | Umkhiqizo ophelelwe yisikhathi / izimo ezingalungile | Sebenzisa isivali esisha, indawo efanele yokupholisa |
| Ukwehluleka kwamalunga | Ukunyakaza ngokweqile / ukwakheka okungalungile | Dala kabusha ijoyinti, sebenzisa induku yangemuva |
Ama-sealant e-silicone aphakathi kwezixazululo zokuvala ezihlala isikhathi eside ezitholakalayo—kodwa kuphela uma zisetshenziswa kahle.izinkinga ezivamile kanye nokulungiswa kwazo, ungaqinisekisa impilo yesevisi ende, ukugcinwa okuncishisiwe, kanye nokusebenza kangcono kwephrojekthi.
At Izivalo zeSiway, sihlinzekaizivalo ze-silicone ezisebenza kahle kakhuluyakhelwe ukunciphisa lezi zinkinga. Xhumana nathiithimba lokusekela lobuchwephesheukuze uthole izincomo eziqondene nephrojekthi.
Umbuzo 1. Kungani i-silicone sealant yami inganamatheli kahle?
Lokhu kuvame ukwenzeka ngenxaukungcoliswa kwendawo, umswakama, noma ukusebenzisa isivalo esingafanele se-substrateHlanza futhi womise indawo njalo, sebenzisa i-primer uma kudingeka, bese ukhetha i-silicone sealant efanele yokuhlanza izinto ezibucayi njengensimbi noma itshe.
Umbuzo 2. Ngingawalungisa kanjani amabhamuza noma izimbobo ku-silicone sealant?
Ukuvuvukala kuvame ukwenzeka uma i-substrate imanzi noma uma i-sealant ifakwa ngokushesha kakhulu. Susa ingxenye ehlulekile, yomise ngokuphelele indawo, bese uphinda uyifaka endaweni epholile.ubuhlalu obuhamba kancane, obuqhubekayoUkuze uthole imiphumela yobungcweti, bheka ku-I-ASTM C920-18(2024)iziqondiso zohlelo lokusebenza
Umbuzo 3. Kungani i-silicone sealant iphenduka isikhunta ezindlini zangasese?
Ngisho ne-silicone “ehlanzekile” ingakha isikhunta uma itholakala ku-umswakama oqhubekayo kanye nokungena komoya okungekuhleSebenzisa i-silicone sealant ehlanzekile enezithako ze-fungicide futhi ugcine indawo yomile uma kungenzeka. Ukuhlanza njalo ngezihlanzi ezingakhuculi kusiza ukwandisa isikhathi sokuphila.
Umbuzo 4. Kuthatha isikhathi esingakanani ukuthi i-silicone sealant iphole ngokuphelele?
Iningi lama-silicone liyaphulukisa2–3 mm ngosukukodwa ukuqina okuphelele kungathatha isikhathi esingafika ku-Izinsuku ezingu-7–14, kuye ngokuthi ubuhlalu buqine kangakanani, umswakama, kanye nokushisa. Hlola njalo amaphepha edatha yobuchwepheshe bomkhiqizi ukuze uthole izikhathi eziqondile zokuqina.
Umbuzo 5. Ngingafaka i-silicone entsha phezu kwe-silicone endala?
Cha. I-silicone endala kumele ibekususwe ngokuphelelengoba isivali esisha ngeke sinamathele kahle. Sebenzisa i-sealant remover noma i-mechanical scraper ngaphambi kokufaka kabusha.
Umbuzo 6. Kungani i-silicone sealant yami ephulukisiwe iqhekeka noma incipha?
Lokhu kuvame ukubangelwaukusebenzisa uhlobo olungalungile lwe-sealant kumajoyinti anyakaza kakhulunoma ukufaka ubuhlalu obuncane kakhulu. Kumajoyinti esakhiwo noma okunwetshwayo, khetha i-structrual silicone sealant ehlangabezanaIzindinganiso ze-ISO 11600 zamandla okunyakaza.
