I-silicone building sealant imele eyona nto iphambili kwisayensi yezinto zokwakha, eyenzelwe ukujongana neemfuno ezibalulekileyo zokusebenza ezingenakukwazi ukuhlangabezana ne-sealants zemveli. Njenge-polymer ye-elastomeric esebenza kakhulu, inika umsebenzi ongenakuthelekiswa nanto wobume besakhiwo, ukuthintela imozulu, kunye nobude bexesha.
Ukwakhiwa kunye neNkqubo
Zenziwe ngee-polymers ze-silicone eziqiniswe nge-silica, ezi sealants ziyanyangeka nge-acetoxy okanye iindlela ezingathathi cala zibe zii-elastomers eziqinileyo neziguquguqukayo. Iimpawu eziphambili ze-molecular ziquka:
1. Umqolo weSiloxane obonelela ngozinzo lwe-UV kunye nokumelana nobushushu
2. Amaqela asebenzayo ngokwendalo avumela ukunamathela kwe-substrate
3. Izongezo eziphambili (i-fungicides, izikhuthazi zokunamathela) eziphucula ukusebenza
Iingenelo zoKusebenza ezibalulekileyo
1. Indawo yokuhlala yoHamba lweZakhiwo
- Igcina ukuthembeka ngokusebenzisa intshukumo yamalungu e-±50% (imigangatho ye-ASTM C920), ithintela ukwaphuka koxinzelelo kwizinto zokwakha eziguqukayo.
2. Ukuqina Okukhulu Kwendalo Esingqongileyo
Isebenza ukusuka kwi -73°C ukuya kwi +260°C ngaphandle kokubola kwe-thermoplastic, iphumelela ngaphezu kwezinye iindlela ze-organic polymer.
3.Ukhuseleko lweMvulophu yeSakhiwo
Idala imiqobo engapheliyo yokuthintela amanzi, ebalulekileyo kwezi zinto zilandelayo:
- Iinkqubo zodonga lwamakhethini
- Iinkqubo zokwandisa amaqabane
- Izicelo zokutywina umjikelezo
4. Ukuhambelana kwezinto
Isebenzisana kakuhle neentlobo ngeentlobo zezityalo, kuquka:
Iglasi | I-Aluminiyam eyosiweyo | Ikhonkrithi | Igranite | I-PVC Ngaphandle kokubangela ukubola kwe-galvanic okanye ukuwohloka komphezulu.
5. Ukusebenza kakuhle kococeko
Iifomyula eziqinisekiswe yi-NSF zithintela ukukhula kweentsholongwane kwiindawo ezimanzi (kwiindawo ezingqonge ichibi, kwiindawo zokulungisa ukutya).
Isikhokelo seNkcazelo yoBugcisa
| Ipropati | Uhlobo lwe-Acetoxy | Uhlobo olungathathi cala |
|---|---|---|
| Indlela Yokunyanga | I-Acetic Acid | Utywala/iKetoxime |
| Ukuhambelana kweSubstrate | Ayiyoyesinyithi | Zonke izixhobo |
| Ubushushu beNkonzo | -50°C ukuya kwi-180°C | -73°C ukuya kuma-260°C |
| Amandla okuHamba | ±25% | ±50% |
Iprotokholi yesicelo sobunjineli
1. Ukulungiswa komphezulu
Ukucoca isinyibilikisi (i-isopropyl alcohol)
Ukukrala kwiindawo ezingenamibhobho
Isicelo sokuqala apho kuchaziwe khona
2. Ulungelelwaniso loFakelo
Ukufakelwa kwentonga yomqolo kwiindawo zokudibanisa >6mm
I-engile ye-nozzle engama-45° kuxinzelelo olungaguqukiyo
Ukufaka izixhobo ngaphakathi kwemizuzu eli-10 emva kokufaka isicelo
3. Isayensi yokunyanga
Ukwakheka kolusu: imizuzu eli-15-30
Unyango olupheleleyo: iiyure ezingama-24-72 (kuxhomekeke kubunzulu)
Isiphumo sokukhawulezisa umswakama
Ukuthotyelwa kweMithetho
Iifomyula eziphambili ziyahlangabezana:
Iimfuno ze-ASTM C920 Class 100/50
Uhlu lwe-ISO 11600 F&G
Iikhredithi zezinto ze-LEED v4.1
