I-Sealant isho impahla yokubopha uphawu edonswa ngesimo sendawo yokubekwa uphawu, akulula ukugeleza, futhi inokunamathelisa okuthile.
Kuyinto enamathela okusetshenziselwa ukugcwalisa izikhala zokucushwa zokubekwa uphawu. Inemisebenzi yokuvuza, okungangeni manzi, i-anti-vibration, ukufakwa okuzwakalayo kanye nokufakelwa kokushisa. Imvamisa, izinto ezomile noma ezingezona ezomile ezifana ne-asphalt, resin yemvelo noma i-sonthetic resin, irabha yemvelo noma i-chorthetic emnyama enjenge-talc, ubumba, i-asbestos emnyama, i-asbestos ingeziwe. Amapulasitiki, ama-sollents, ama-ejenti okulapha, ama-accelerator, njll. Kungahlukaniswa ngezigaba ezintathu: I-Elastic Sealant, i-gasket yokubopha uphawu lokubopha uphawu lokubopha uphawu. Kusetshenziswa kabanzi ekubekeni uphawu kokwakhiwa, ezokuhamba, izinsimbi zikagesi nezingxenye.
Kunezinhlobo eziningi zama-sealants: ama-balants abizo, ama-polyurethane sealants, ama-sealars e-acrylurethane, ama-sealars e-anaerobic, ama-balances we-neoprene, ama-sealars we-PVC, kanye nama-sealants asphalt.
Izici eziphambili ze-sealant
(1) Ukubukeka: Ukubonakala kwe-sealant kunqunywa ikakhulu ukuhlakazwa kwe-filler esisekelweni. I-filler yi-powder eqinile. Ngemuva kokuhlakazwa yi-KINESERER, i-grinder kanye nomshini weplanethi, ingahlakazwa ngokulinganayo enjoloba esekelweni ukuze wakhe unamathisela omuhle. Inani elincane lenhlawulo noma isihlabathi elincanyana lamukelekile futhi lijwayelekile. Uma i-filler ingahlakazwa kahle, kuzovela izinhlayiya eziningi ezinobunzima. Ngaphezu kokuhlakazwa kwama-fillers, ezinye izinto kuzothinta nokubukeka komkhiqizo, njengokuxubana kokungcoliswa kwenhliziyo, ukugcwala, njll la macala athathwa njengokubukeka kahle.
(2) Ubulukhuni
(3) Amandla asheshayo
(4) Elongation
(5) Tensile modulus kanye nekhono lokuxoxisana
(6) Ukunamathela ku-substrate
(7) Ukukhishwa: Lokhu ukusebenza kokwakhiwa kwe-sealant into esetshenziselwa ukukhombisa ubunzima be-sealant lapho isetshenziswa. I-glue emnene kakhulu izoba ne-extuderable empofu, futhi kuzoba nzima kakhulu ukunamathisela lapho isetshenziswa. Kodwa-ke, uma ngabe i-glue yenziwe inciphile kakhulu ngokubheka ukweqiwa, kuzothinta i-thixotropy ye-sealant. Ukukhishwa kungalinganiswa ngendlela echazwe kwiZinga Likazwelonke.
(8) UThixotropy: Le ngenye into yokwenza umsebenzi wokwakha we-sealant. I-Thixotropy ihlukile kobubi, okusho ukuthi i-sealant ingashintsha kuphela ukwakheka kwayo ngaphansi kwengcindezi ethile, futhi ingalondoloza ukwakheka kwayo lapho kungekho mandla angaphandle. ukwakheka ngaphandle kokugeleza. Ukunqunywa kwe-sag kuchazwe yiNational Standard ukwahlulela kwe-Thixotropy ye-sealant.
