I-Sealant yinto yokutywina eguqukayo ibe yimo yomphezulu wokutywina, akulula ukuyihambisa, kwaye inokuncamathela okuthile. Yi-glue esetyenziselwa ukugcwalisa izikhewu phakathi kwezinto ukuze idlale indima yokutywina. Inemisebenzi yokulwa nokuvuza, ukungangeni manzi, ukuthintela ukungcangcazela, ukuthintela isandi kunye nokuthintela ubushushu.
Ihlala isekelwe kwizinto ezomileyo okanye ezingomiyo ezifana ne-asphalt, i-resin yendalo okanye i-resin yokwenziwa, irabha yendalo okanye irabha yokwenziwa. Yenziwe ngezinto zokuzalisa ezingasebenziyo ezifana ne-talc, udongwe, i-carbon black, i-titanium dioxide kunye ne-asbestos, uze wongeze iiplastiki, izinyibilikisi, ii-curing agents, ii-accelerators, njl.njl.
Uhlu lwee-sealants
I-Sealant inokwahlulwa ibe yi-elastic sealant, i-liquid sealant gasket kunye neendidi ezintathu ze-sealing putty.
Ngokwendlela yokwakheka kweekhemikhali:Ingahlulwahlulwa ibe luhlobo lwerabha, uhlobo lweresin, uhlobo olusekwe kwioyile kunye nesealant yepolymer yendalo. Le ndlela yokuhlela inokufumanisa iimpawu zezinto zepolymer, igqibe ekubeni ziyamelana nobushushu bazo, ziyatywinwa kwaye ziyazilungelelanisa neentlobo ngeentlobo zemidiya.
Uhlobo lwerabha:Olu hlobo lwesitywini lusekelwe kwirabha. Iirabha ezisetyenziswa kakhulu yirabha ye-polysulfide, irabha ye-silicone, irabha ye-polyurethane, irabha ye-neoprene kunye nerabha ye-butyl.
Uhlobo lweresin:Olu hlobo lwesitywini lusekelwe kwi-resin. Ii-resin ezisetyenziswa kakhulu yi-epoxy resin, i-unsaturated polyester resin, i-phenolic resin, i-polyacrylic resin, i-polyvinyl chloride resin, njl.
Isekelwe kwioyile:Olu hlobo lwesitywini lusekelwe kwioyile. Iioyile ezisetyenziswa rhoqo ziioyile zemifuno ezahlukeneyo ezifana neoyile ye-linseed, ioyile ye-castor kunye neoyile ye-tung, kunye neeoyile zezilwanyana ezifana neoyile yeentlanzi.
Uhlu ngokwesicelo:inokwahlulwahlulwa ibe luhlobo lobushushu obuphezulu, uhlobo lokumelana nokubanda, uhlobo loxinzelelo njalo njalo.
Uhlu ngokweempawu zokwenza ifilimu:Ingohlulwa ibe luhlobo lokunamathela okomileyo, uhlobo olomileyo oluxobukayo, uhlobo olunamathelayo olungomiyo kunye nohlobo lwe-viscoelastic olomileyo kancinci.
Uhlu ngokwendlela olusetyenziswa ngayo:Ingahlulwahlulwa ibe yi-construction sealant, i-vehicle sealant, i-insulation sealant, i-packaging sealant, i-mining sealant kunye nezinye iintlobo.
Ngokwendlela esebenza ngayo emva kokwakhiwa:Ingohlulwa ibe ziintlobo ezimbini: i-curing sealant kunye ne-semi-curing sealant. Phakathi kwazo, i-curing sealant inokwahlulwa ibe yi-rigid and flexible. I-rigid sealant iqinile emva kwe-vulcanization okanye i-solidification, kwaye ayifane ibe ne-elasticity, ayinakugotywa, kwaye idla ngokuba nemithungo ayinakushukunyiswa; i-flexible sealants iyanwebeka kwaye ithambile emva kwe-vulcanization. I-non-curing sealant yi-soft solidifying sealant esagcina i-non-drying tackifier emva kokwakhiwa kwaye iqhubekeka ifudukela kwimeko yomphezulu.
