I-Sealant yimpahla yokutywina ekhubaza kwimilo yendawo yokutywina, akulula ukuhamba, kwaye inonamathela okuthile. Yinto encamathelayo esetyenziselwa ukugcwalisa izithuba phakathi kwezinto ezidlala indima yokutywina. Inemisebenzi ye-anti-leakage, i-waterproof, i-anti-vibration, i-sound insulation kunye nokushisa ukushisa.
Ngokuqhelekileyo isekelwe kwizinto ezomileyo okanye ezingasomisiyo ze-viscous ezifana ne-asphalt, i-resin yendalo okanye i-resin yokwenziwa, i-rubber yendalo okanye i-rubber yokwenziwa. Yenziwe nge-inert fillers njenge-talc, udongwe, i-carbon black, i-titanium dioxide kunye ne-asbestos, kwaye yongeza i-plasticizers, i-solvents, i-agent ephilisayo, i-accelerators, njl.
Ukuhlelwa kwee-sealants
I-Sealant inokwahlulwa ibe yi-elastic sealant, i-liquid sealant gasket kunye neendidi ezintathu zokutywinwa kwe-putty.
Ngokohlelo lokwakheka kweekhemikhali:inokwahlulwa ibe luhlobo lwerabha, uhlobo lwe-resin, uhlobo olusekwe kwi-oyile kunye ne-polymer sealant yendalo. Le ndlela yokuhlela inokufumanisa iimpawu zemathiriyeli yepolymer, infer ukumelana nobushushu babo, ukutywinwa kunye nokuguquguquka kwimidiya eyahlukeneyo.
Uhlobo lwerabha:Olu hlobo lwe-sealant lusekelwe kwirubha. Iirubha ezisetyenziswa ngokuqhelekileyo ziyirabha ye-polysulfide, irabha ye-silicone, irabha ye-polyurethane, irabha ye-neoprene kunye ne-butyl irabha.
Uhlobo lwe-resin:Olu hlobo lwe-sealant lusekelwe kwi-resin. Ngokuqhelekileyo i-resin esetyenziswayo yi-epoxy resin, i-polyester engaxutywanga, i-phenolic resin, i-polyacrylic resin, i-polyvinyl chloride resin, njl.
Isekwe kwi-oyile:Olu hlobo lwe-sealant lusekelwe kwioli. Iioyile ezisetyenziswa ngokuqhelekileyo ziioyile ezahlukeneyo zemifuno ezifana neoli ye-linseed, ioyile yecastor kunye neoyile ye-tung, kunye neoyile yezilwanyana ezifana neoyile yentlanzi.
Ukuhlelwa ngokwesicelo:inokwahlulwa ibe yintlobo yobushushu obuphezulu, uhlobo lokumelana nokubanda, uhlobo loxinzelelo njalo njalo.
Ukuhlelwa ngokweempawu zokwenza ifilimu:Inokwahlulwa ibe luhlobo oluncamathelayo olomileyo, uhlobo olomileyo olucwetywayo, uhlobo oluncangathi olungomileyo kunye nohlobo lwe-viscoelastic eyomileyo.
Ukuhlelwa ngokusetyenziswa:Inokwahlulwa ibe yi-sealant yokwakha, i-car sealant, i-insulation sealant, i-packaging sealant, i-mining sealant kunye nezinye iintlobo.
Ngokokusebenza emva kokwakhiwa:inokwahlulwa ibe ziindidi ezimbini: ukunyanga i-sealant kunye ne-semi-curing sealant. Phakathi kwabo, ukunyanga i-sealant inokwahlulwa ibe lukhuni kwaye iguquguquke. I-Rigid sealant iqinile emva kokutshatyalaliswa okanye ukuqina, kwaye kunqabile ukuba ne-elasticity, ayikwazi ukugoba, kwaye ngokuqhelekileyo i-seams ayinakushukunyiswa; izinto zokutywina eziguquguqukayo ziyalastiki kwaye zithambile emva kokwenziwa vulcanization. Isitywina esinganyangekiyo sisitywina esithambileyo esiqinisayo esagcina i-tackifier engomisi emva kokwakhiwa kwaye ifudukela ngokuqhubekayo kumphezulu womhlaba.
