I-silicone building sealant imelela ingqalasizinda yesayensi yezinto zokwakha, eyenzelwe ukubhekana nezidingo zokusebenza ezibalulekile ezingenakuhlangatshezwa yi-sealants yendabuko. Njenge-polymer esebenza kahle kakhulu, inikeza ukusebenza okungenakuqhathaniswa kokuqina kwesakhiwo, ukuvikela isimo sezulu, kanye nokuphila isikhathi eside.
Ukwakheka kanye Nendlela Yokusebenza
Njengoba zenziwe ngama-polymer e-silicone aqiniswe nge-silica, lezi zi-sealant ziyaphulukiswa nge-acetoxy noma izindlela ezingathathi hlangothi zibe ama-elastomer aqinile, aguquguqukayo. Izici ezibalulekile zama-molecule zifaka:
1. Umgogodla we-Siloxane ohlinzeka ngokuqina kwe-UV kanye nokumelana nokushisa
2. Amaqembu asebenzayo avumela ukunamathela kwe-substrate
3. Izithasiselo ezithuthukisiwe (imithi yokubulala isikhunta, abagqugquzeli bokunamathela) ezithuthukisa ukusebenza
Izinzuzo Zokusebenza Ezibalulekile
1. Indawo Yokuhlalisa Ukunyakaza Kwesakhiwo
- Igcina ubuqotho ngokunyakaza kwamalunga okungu-±50% (izindinganiso ze-ASTM C920), ivimbela ukuqhekeka kokucindezeleka ezakhiweni eziguquguqukayo.
2. Ukuqina Kwemvelo Okukhulu
Isebenza kusukela ku--73°C kuya ku-+260°C ngaphandle kokuwohloka kwe-thermoplastic, isebenza kangcono kunezinye izindlela ze-polymer eziphilayo.
3.Ukuvikelwa Kwezimvilophu Zokwakha
Kudala izithiyo ezingangeni manzi eziqhubekayo, ezibalulekile ku:
- Izinhlelo zodonga lwamakhethini
- Izinhlelo zokuhlanganisa ezinwetshiwe
- Izicelo zokuvala umjikelezo
4. Ukuhambisana kwezinto ezibonakalayo
Ihlangana kahle nezingxenye ezahlukahlukene ze-substrate kufaka phakathi:
Ingilazi | I-Aluminium Enodisiwe | Ukhonkolo | I-Granite | I-PVC Ngaphandle kokubangela ukugqwala kwe-galvanic noma ukuwohloka kwendawo.
5. Ukusebenza Okuhlanzekile
Amafomula aqinisekiswe yi-NSF avimbela ukukhula kwamagciwane ezindaweni ezimanzi (ezizungezile ichibi, izindawo zokucubungula ukudla).
Umhlahlandlela Wokucaciswa Kobuchwepheshe
| Impahla | Uhlobo lwe-Acetoxy | Uhlobo Olungathathi hlangothi |
|---|---|---|
| Indlela Yokwelapha | I-Acetic Acid | Utshwala/i-Ketoxime |
| Ukuhambisana kwe-Substrate | Okungeyona insimbi | Zonke izinto zokwakha |
| Izinga Lokushisa Lesevisi | -50°C kuya ku-180°C | -73°C kuya ku-260°C |
| Amandla Okunyakaza | ±25% | ±50% |
Iphrothokholi Yesicelo Esinjiniyela
1. Ukulungiselela Okungaphezulu
Ukuhlanza i-solvent (i-isopropyl alcohol)
Ukuguguleka ezindaweni ezingenazo izimbobo
Isicelo se-Primer lapho kuchaziwe khona
2. Ukunemba Kokufakwa
Ukufakwa kwenduku yangemuva yamalunga >6mm
I-engeli yomlomo engu-45° ngokucindezela okungaguquki
Ukufaka amathuluzi kungakapheli imizuzu eyi-10 kusukela ekusetshenzisweni
3. Isayensi Yokwelapha
Ukwakheka kwesikhumba: imizuzu eyi-15-30
Ukwelashwa okuphelele: amahora angu-24-72 (kuncike ekujuleni)
Umphumela wokusheshisa umswakama
Ukuthobela Imithetho
Izinhlobo ezihamba phambili zihlangana:
Izidingo ze-ASTM C920 Class 100/50
Ukuhlukaniswa kwe-ISO 11600 F&G
Amakhredithi ezinto ezibonakalayo e-LEED v4.1
