I-silicone sealant ingenye yezinto zokunamathisela ezisebenziseka kakhulu kanye nezinto zokuvala ezakhiweni nasekukhiqizeni kwanamuhla. Ukuguquguquka kwayo, impilo yayo ende, kanye nokumelana nesimo sezulu kanye nokushisa okuphezulu kwenza kube ukukhetha kokuqala kochwepheshe emhlabeni jikelele.
Nokho, ukukhethauhlobo olufanele lwe-silicone sealantAkulula njengoba kubukeka. Ukukhetha okungalungile kungaholela ekuhlulekeni kokunamathela, ukuvuza, ukuqhekeka, noma ukulungiswa kabusha okubizayo. Lo mhlahlandlela unikeza i-athikili echazayo.uhlaka lwezinga lobuchwepheshe, ngokusekelwe ezindinganisweni zomhlaba wonke (ASTM, ISO, GB), ukukusiza ukhethe i-silicone sealant efanele yephrojekthi yakho.
1. Qondanisa i-Sealant ne-Substrate (Izinto Ezingaphezulu)
Ama-silicone sealant awahambisani kahle nazo zonke izinto ezisetshenziswayo. Ukwakheka okungalungile kungabangela ukugqwala noma ukwehluleka kokubopha.
-Ingilazi kanye ne-Glazing
--Sebenzisai-silicone yokwelapha engathathi hlangothiIzakhi ze-acetoxy (ezine-asidi) zingalimaza izinsimbi ezifakwe ezinhlelweni zokugqwala.
--Isibonelo: Amaphrojekthi odonga lwamakhethini afanaIsiteshi Sesitimela SaseNingizimu saseBeijingkusetshenziswe i-silicone engathathi hlangothi ukuqinisekisa ukuqina kweminyaka engaphezu kwengu-20.
-Amaphaneli e-Aluminium ne-Metal
--Kunconywa ama-silicone esakhiwo ahlanzekile angathathi hlangothi ukuze kugwenywe ukugqwala noma ukubola.
--ASTM C1184 icacisa izidingo zokusebenza kwezivikelo zeglasi zesakhiwo.
-Ukhonkolo, Amatshe, kanye Nokwakha Amatshe
--Izingqimba ezinezimbobo zidinga ama-primer ngaphambi kokufaka i-silicone ukuvimbela ukumuncwa kanye nokunamathela okubuthakathaka.
--I-silicone engathathi hlangothi enekhono eliphezulu lokunyakaza (±50%) iyathandwa kakhulu kumajoyinti okunwebeka.
-Amapulasitiki (i-PVC, i-Polycarbonate, i-Acrylic)
--Akuwona wonke ama-silicone anamathela kahle. Ukuhlolwa kokufaneleka kubalulekile ngoba amanye amapulasitiki akhipha amafutha avimbela ukubola.
--Ezindlini zokuvala zikagesi, ama-silicone e-RTV (i-Room Temperature Vulcanizing) avamile.
Icebiso Lochwepheshe:Cela njaloIshidi Ledatha Lobuchwepheshe (i-TDS)kusuka kumhlinzeki wakho bese uhlola ama-substrate anconyiwe. Kumaphrojekthi amakhulu, yenza ukuhlolwa kokuhambisana ngaphambi kokusetshenziswa ngobuningi.
2. Ukusetshenziswa Kwangaphakathi vs. Kwangaphandle
Izindawo ezahlukene zidinga ukwakheka okuhluke kakhulu.
1. Izicelo Zangaphakathi
--Izivalo ze-silicone ezihlanzekile ezineizithasiselo zokulwa nesikhuntazilungele kakhulu amakhishi, izindlu zangasese, kanye nemigudu ye-HVAC.
--Zivimbela ukukhula kwesikhunta esimnyama ezindaweni ezinomswakama futhi ziyahlolwa ngokusho kwe-ISO 846 ukuze kutholakale ukumelana nezinto eziphilayo.
--Izakhi ze-Low-VOC (i-volatile organic compound) ziyanconywa ukuze zihlangabezane nezindinganiso zesimanje zokwakha eziluhlaza (i-LEED, i-BREEAM).
2. Izicelo Zangaphandle
--Izivalo zokuvala kumele zimelane nazoImisebe ye-UV, i-ozone, ukushintshashintsha kwezinga lokushisa, kanye nokuchayeka emvuleni.
--I-silicone yokwelapha engathathi hlangothi enekhono eliphezulu lokunwebeka (kufika ku-400%) iqinisekisa ukuthi uphawu luhlala lungashintshi ngaphansi kokukhula kokushisa.
--Isibonelo:Indlunkulu ye-CCTV eBeijingkudingeka i-silicone sealant esebenza kahle kakhulu ukuze kuhlanganiswe ama-façade joints abhekene nobusika obungu-20°C kanye nehlobo lika-+40°C.
3. Izici Zokucindezeleka Kwezemvelo Nezemishini
Ngaphambi kokukhetha i-sealant, hlolaizimo zokucindezelekaiphrojekthi yakho izobhekana nalokhu:
1). Ukumelana Nokushisa
--Ama-silicone ajwayelekile: -40°C kuya ku-+150°C
--Ama-silicone ashisa kakhulu: ukuvezwa okuqhubekayo kuze kufike ku-+300°C
--Isibonelo: Ama-gasket ezimoto asebenzisa i-silicone ebomvu enokushisa okuphezulu ukuze amelane nokushisa kwenjini.
2) .Umswakama kanye Nomswakama
--Izindlu zangasese namakhishi: sebenzisa i-silicone ehlanzekile enezivimbeli zesikhunta.
--Amabhuloho angaphandle kanye nemihubhe: ukumelana nokucwiliswa emanzini kubalulekile.
3). Amandla Okunyakaza
--Kuchazwe yi-ASTM C719 (ukunyakaza kwe-sealant).
--Amalunga okwandisa emaceleni: Kudingeka ukunyakaza okungu-±50%.
--Izivalo zokuvala ezinyakazayo kancane (±12.5%) zilungele kuphela izikhala ezincane.
4. Izicelo Zesakhiwo vs. Ezingezona Ezakhiwe
1). Izivalo zeSilicone zesakhiwo
--Isetshenziswa ekufakeni amakhethini odongeni kanye nokubopha okuthwala umthwalo.
--Kumele ihambisane ne-ASTM C1184 noma i-GB 16776 (eShayina).
--Dinga ukulungiswa kwendawo okunembile, ukwakheka kwamalunga, kanye nokulawulwa kwekhwalithi ngesikhathi sokufakwa.
2) .Ama-Silicone Enhloso Ejwayelekile
--Iyabiza kancane, kulula ukuyisebenzisa, futhi ifanele ukulungiswa kwendlu kanye nokuvalwa okungenasidingo.
--Isikhathi sokuphila ngokuvamile sifushane (iminyaka emi-5-10) uma siqhathaniswa nama-silicone esakhiwo (iminyaka engama-20-30).
5. Izitifiketi kanye namazinga ekhwalithi
Abathengi abangochwepheshe kufanele baqinisekise njalo izitifiketi:
--ISO 9001 kanye ne-ISO 14001- Izinhlelo zokuphatha ikhwalithi kanye nemvelo.
--Izindinganiso ze-ASTM– C920 (ama-sealant e-elastomeric joint), C1184 (ukucwebezelisa kwesakhiwo).
--Izindinganiso ze-GB (eShayina)– GB/T 14683 (izinto zokuvala izakhiwo).
--Uphawu lwe-CE (eYurophu)– Iqinisekisa ukuhambisana nezindinganiso zokuphepha nokuqina zaseYurophu.
Lezi zitifiketi zinciphisa izingozi zephrojekthi futhi ziqinisekisa ukuhambisana nezidingo zikahulumeni nezemboni.
6. Kulula Ukusebenzisa
I-Silicone ye-One-Component (RTV)
--Amakhatriji noma amasoseji alungele ukusetshenziswa.
--Yelapha ngomswakama ozungezile, ngokuvamile zingakapheli amahora angu-24-48.
--Kufanelekela izinhlelo zokusebenza zesayithi lapho isivinini kanye nokulula kubalulekile khona.
I-Silicone Enezingxenye Ezimbili
--Kudinga ukuxuba, kodwa kuphulukiswa ngokushesha kakhulu futhi njalo.
--Kukhethwa kakhuluukucwebezela kwefektrifuthiimigqa yokuhlanganisa yezimboni.
--Isibonelo: Kusetshenziswa emigqeni yokukhiqiza odongeni lwekhethini ezenzakalelayo ukuqinisekisa ukuqiniswa okuqhubekayo.
7. Ukusebenza Kwezindleko vs. Umjikelezo Wokuphila
Kuyayenga ukukhetha i-sealant ebiza kancane, kodwa izindleko zomjikelezo wokuphila zibaluleke kakhulu.
--I-sealant eshibhile: ukunamathela okuphansi, ukushintsha kombala, ukuqhekeka kungakapheli iminyaka emi-3-5.
--I-silicone yesakhiwo se-premium: Iminyaka engama-20–30 yempilo yesevisi, izindleko zokulungisa eziphansi, kanye ne-ROI engcono yesikhathi eside.
--Emisebenzini emikhulu yokwakha,izindleko zokuvala zingaphansi kwe-1% yesabelomali esiphelele se-façade, kodwa ukwehluleka kwe-sealant kungabangela izigidi zokulungiswa.
Umhlahlandlela Wokukhetha Okusheshayo
| Uhlobo Lohlelo Lokusebenza | I-Silicone Sealant Enconyiwe | Amazinga/Amanothi |
|---|---|---|
| Indlu yokugezela / Ikhishi | Isivalo se-Silicone Sanitary | I-ISO 846 ihlolwe, ilwa nesikhunta |
| Ifasitela kanye nodonga lwekhethini | I-Silicone Yesakhiwo Esingathathi Nhlangothi Yokwelapha | I-ASTM C1184, GB 16776 |
| Amajoyinti Okunwebeka (Ingaphambili) | I-Silicone Engathathi hlangothi Ehamba Kakhulu (±50%) | I-ASTM C719 |
| Izimoto / Injini | I-Silicone Enokushisa Okuphezulu | Imelana nokushisa okufika ku-300°C |
| Ukulungiswa Kwezinto Zokuzenzela | I-Silicone Yenhloso Ejwayelekile | Kulula ukuyisebenzisa, kuyabiza kakhulu |
Ukukhetha i-silicone sealant efanele kudinga ukuhlolwaizinhlaka, indawo ezungezile, ukucindezeleka komshini, kanye nezindinganiso zesitifiketiNgezinhlelo zokusebenza ezibalulekile ezifana nezindonga zamakhethini, amajoyinti okunweba, kanye nezingxenye zezimoto, sebenzisa njalo izithiyo zokuvala eziqinisekisiwe ezisebenza kahle ukuqinisekisa ukuphepha nokuphila isikhathi eside.
At Izivalo zeSiway, sihlinzeka ngemikhiqizo eqinisekiswe yi-ISO kanye ne-ASTM eyenzelwe ukwakhiwa, ukusetshenziswa kwezimoto kanye nezimboni. Xhumana nethimba lethu ku-cela amashidi edatha obuchwepheshe, izincomo zephrojekthi ethile, noma amasampula wamahhala.
