Iyini i-silicone yesakhiwo?

I-Silicone structural sealant iyisinamathiselo sesakhiwo esiphilisayo esingathathi hlangothi esiklanyelwe ngokukhethekile ukuhlanganiswa okuhlangene kwesakhiwo ekwakheni izindonga zamakhethini.Ingakhishwa kalula futhi isetshenziswe ezinhlobonhlobo zezimo zokushisa, futhi yelashwa ibe yi-modulus ephakeme kakhulu, ehlala njalo, irabha ye-silicone enwebeka kakhulu ngomswakama emoyeni.Obondeni lwamakhethini engilazi, isetshenziselwa into enamathelayo ye-silicone yesakhiwo phakathi kwepuleti nohlaka lwensimbi, ipuleti nepuleti, kanye nepuleti nombambo lwengilazi.Kuyinto eyinhloko yokucindezeleka yohlaka olufihliwe kanye nodonga lwamakhethini ohlaka olufihliwe kancane, futhi kuyisici esibalulekile esithinta ukuphepha kodonga lwamakhethini engilazi.Inezici zokumelana ne-UV, ukumelana ne-ozone, ukumelana nesimo sezulu esihle nokunamathela okuqinile.Ngaphambi kokusetshenziswa, ukuhlolwa kokuhambisana kwengilazi, uhlaka lwensimbi, i-spacer, i-gasket, i-positioning block nezinye izinsimbi kufanele zenziwe, futhi ukuhlolwa kokuhambisana kungasetshenziswa kuphela ngemva kokuphumelela ukuhlolwa.
Ukwahlukanisa

Ukusebenza okuphezulu kweSilicone StructuralI-Sealant
Umkhiqizo ungakhiqiza ukunamathela okuhle kakhulu ezintweni eziningi zokwakha ngaphandle kwe-primer.
Inezici zomkhiqizo ezihamba phambili ezilandelayo:
1. Kulula ukuyisebenzisa: Ingakhishwa futhi isetshenziswe nganoma yisiphi isikhathi.
2. Ukwelapha okungathathi hlangothi: kulungele izinto eziningi zokwakha ngaphandle kokusabela okubi noma ukugqwala.
3. Ukunamathela okuhle kakhulu: akukho primer edingekayo, futhi ingakha ukunamathela okuqinile ngezinto eziningi zokwakha.
4. Ukuzinza okuhle kakhulu kokulwa nokuguga.
5. Ngemva kokwelapha, inokusebenza kwemodulus ephezulu futhi ingathwala ukunwetshwa nomthamo wokuthutha ongu-±25% wesixhumi esibonakalayo.
6. Ukuhlanganiswa kwesakhiwo, amasampula ezinto ezibonakalayo kanye nemidwebo yokuhlanganisa kufanele kuthunyelwe enkampanini yokuhlola echwepheshile ukuze ihlolwe futhi ibuyekezwe kusenesikhathi.
 
I-Silicone structural sealant engathathi hlangothi ecacile
Ingxenye eyodwa, ukwelapha okungathathi hlangothi, okuklanyelwe ngokukhethekile ukuhlanganiswa okuhlanganisiwe kwezakhiwo ezicwebezelayo kuma-façade ezakhiwo.Ingakhishwa kalula futhi isetshenziswe ezinhlobonhlobo zezimo zokushisa.Thembela kumswakama osemoyeni ukuze welaphe ube yimodulus ephezulu ehlala isikhathi eside, irabha ye-silicone enwebeka kakhulu.Umkhiqizo awudingi i-primer engilazini, futhi ungakhiqiza ukunamathela okuhle kakhulu.Inezici zomkhiqizo ezihamba phambili ezilandelayo:
1. Kulula ukuyisebenzisa: ingakhishwa futhi isetshenziswe nganoma yisiphi isikhathi
2. Ukwelapha okungathathi hlangothi: akukho mphumela kungqimba lwengilazi elaminethiwe
3. Ukunamathela okuhle kakhulu;
4. Ukuzinza okuhle kakhulu kokulwa nokuguga;
5. Ngemva kokwelapha, inokusebenza okuphezulu kwe-modulus futhi ingathwala ukunwetshwa nomthamo wokuthutha ongu-±25% wesixhumi esibonakalayo;
6. Ukuze kuhlanganiswe isakhiwo, amasampula ezinto ezibonakalayo kanye nemidwebo yomhlangano kufanele kuthunyelwe enkampanini yokuhlola echwepheshile ukuze ihlolwe futhi ibuyekezwe kusenesikhathi.

Umehluko phakathi kwesakhiwoi-sealantfuthi okungezona ezakhiwei-sealant
I-Structural sealant ibhekisela kumandla aphezulu (amandla acindezelayo> 65MPa, amandla e-steel-steel positive tensile bonding> 30MPa, shear strength> 18MPa), ingakwazi ukumelana nemithwalo emikhulu, futhi imelana nokuguga, ukukhathala, ukugqwala, nokusebenza ngaphakathi kwempilo elindelekile.Izinzile, ifanele ukuhlangana okuqinile kwesakhiwo.
I-non-structural sealant inamandla aphansi kanye nokuqina okuncane, futhi ingasetshenziswa kuphela ekuhlanganiseni okuvamile nesikhashana, ukuvala, nokulungisa, futhi ayikwazi ukusetshenziselwa ukuhlanganisa izakhiwo.
Impilo yesevisi yamaphrojekthi wokwakha ngokuvamile ingaphezu kweminyaka engama-50, futhi izingxenye zinengcindezi enkulu futhi eyinkimbinkimbi, ehlobene ngokuqondile nokuphepha kwabasebenzi kanye nempahla.Izinamathiselo zesakhiwo zisetshenziswa kakhulu kwezobunjiniyela, ikakhulukazi ezisetshenziselwa ukuqinisa, ukubambelela, ukubopha, ukulungisa, njll.
