I-Sealant iwuphawu lokuvala olushintshayo lube sesimweni sendawo yokuvala, akulula ukugeleza, futhi inokunamathela okuthile. Yingcina esetshenziselwa ukugcwalisa izikhala phakathi kwezinto ukuze zidlale indima yokuvala. Inemisebenzi ye-anti-leakage, i-waterproof, i-anti-vibration, i-sound insulation kanye nokushisa ukushisa.
Ngokuvamile kusekelwe ezintweni ezomile noma ezingakomi ze-viscous ezifana ne-asphalt, i-resin yemvelo noma i-synthetic resin, irabha yemvelo noma irabha yokwenziwa. Yenziwe ngama-inert fillers afana ne-talc, ubumba, i-carbon black, i-titanium dioxide ne-asbestos, bese wengeza ama-plasticizers, ama-solvents, ama-ejenti okwelapha, ama-accelerator, njll.
Ukuhlukaniswa kwama-sealants
I-Sealant ingahlukaniswa ibe yi-elastic sealant, i-liquid sealant gasket kanye nezigaba ezintathu ze-sealing putty.
Ngokuya ngezigaba zokwakheka kwamakhemikhali:ingahlukaniswa ngohlobo lwenjoloba, uhlobo lwe-resin, uhlobo olususelwa kuwoyela kanye ne-polymer sealant yemvelo. Le ndlela yokuhlukanisa ingathola izici zezinto ze-polymer, ifake ukumelana kwazo nezinga lokushisa, ukubekwa uphawu kanye nokuvumelana nezimo kumidiya ehlukahlukene.
Uhlobo lwerabha:Lolu hlobo lwe-sealant lusekelwe ku-rubber. Amarabha asetshenziswa kakhulu irabha ye-polysulfide, irabha ye-silicone, irabha ye-polyurethane, irabha ye-neoprene nerabha ye-butyl.
Uhlobo lwe-resin:Lolu hlobo lwe-sealant lusekelwe ku-resin. Ama-resin asetshenziswa kakhulu yi-epoxy resin, i-polyester engafakwanga, i-phenolic resin, i-polyacrylic resin, i-polyvinyl chloride resin, njll.
Amafutha:Lolu hlobo lwe-sealant lusekelwe ku-oyela. Amafutha asetshenziswa kakhulu amafutha emifino ahlukahlukene njengamafutha e-linseed, amafutha e-castor namafutha e-tung, namafutha ezilwane afana namafutha ezinhlanzi.
Ukuhlukaniswa ngokuya ngesicelo:ingahlukaniswa ngohlobo lokushisa eliphezulu, uhlobo lokumelana okubandayo, uhlobo lwengcindezi nokunye.
Ukuhlukaniswa ngokuya ngezakhiwo zokwakha ifilimu:Ingahlukaniswa ngohlobo lokunamathela olomile, uhlobo olomile oluxebukayo, uhlobo olunamathelayo olungakomi kanye nohlobo lwe-viscoelastic olomile.
Ukuhlukaniswa ngokusetshenziswa:Ingahlukaniswa i-sealant yokwakha, i-car sealant, i-insulation sealant, i-packaging sealant, i-sealant yezimayini nezinye izinhlobo.
Ngokusho kokusebenza ngemuva kokwakhiwa:ingahlukaniswa ngezinhlobo ezimbili: i-curing sealant kanye ne-semi-curing sealant. Phakathi kwabo, ukuphulukisa i-sealant kungahlukaniswa kube okuqinile futhi okuguquguqukayo. I-Rigid sealant iqinile ngemva kokuqina noma ukuqina, futhi ayivamile ukuba nokunwebeka, ayikwazi ukugoba, futhi ngokuvamile imithungo ayikwazi ukunyakaza; ama-flexible sealants ayanwebeka futhi athambile ngemva kokwenziwa vulcanization. I-sealant engapholi iyisici esithambile esiqinisayo esagcina i-tackifier engomisi ngemva kokwakhiwa futhi ithuthela endaweni engaphezulu ngokuqhubekayo.
