Izinto Zamathoyizi Asemfashinini
"I-Vinyl", "Resin", "PU resin", "PVC", "Polystone", ngikholwa ukuthi abangani abathanda amathoyizi asemfashinini bezwile ngale migomo.
Kuyini lokhu? Ingabe zonke ziyipulasitiki? Ingabe i-resin ibiza kakhulu futhi ithuthuke kakhulu kune-vinyl?
Wonke umuntu udidekile mayelana nalezi zindaba zezinto zemfashini kanye nobuciko.
Kunezinhlobo ezinhlanu eziyinhloko zamapulasitiki ajwayelekile ajwayelekile: i-PE (i-Polyethylene), i-PP (i-Polypropylene), i-PVC (i-Polyvinyl chloride), i-PS (i-Polystyrene) ne-ABS (i-Acrylonitrile-butadiene-styrene Copolymer), i-PVC ne-ABS ivame ukusetshenziswa amathoyizi emfashini.
Futhi sabona ukuthi imisebenzi yomklami othile isebenzisa izinto "ze-resin", futhi eziningi zazo ziyi-PU resin (Polyuracet), iyini i-Polyurethane?
I-PU resin (i-polyurethane) iyinhlanganisela ye-polymer ephilayo evelayo, eyaziwa ngokuthi ipulasitiki yesithupha ngobukhulu.Inobuhle obuthile amapulastiki endabuko ayizinjongo ezinhlanu angenazo.
I-PVC
I-PVC iza ngezindlela ezimbili eziyisisekelo: eqinile futhi evumelana nezimo. Amafomu aqinile empilweni njengamapayipi amanzi, amakhadi asebhange, njll.;imikhiqizo eguquguqukayo iba yinto ethambile futhi enwebekayo ngokungeza ama-plasticizers, njengamajazi emvula, amafilimu epulasitiki, imikhiqizo ephefumulayo, njll.
I-PVC ne-vinyl evame ukusetshenziswa ezithombeni ezidumile ze-PVC empeleni zenziwe nge-PVC (i-polyvinyl chloride), kodwa izinqubo zihlukile. I-PVC ngokuvamile ibhekisela kunqubo yokubumba umjovo, futhi "i-vinyl" empeleni iyinqubo ekhethekile yokukhiqiza ye-PVC ehlanganisa uketshezi "neglue". (isixazululo se-PVC sokunamathisela) sihlanganiswe ngokulinganayo odongeni lwangaphakathi lwesikhunta ngokusebenzisa ukujikeleza kwe-centrifugal.
I-ABS
I-ABS yakhiwe nge-Acrylonitrile (PAN), Butadiene (PB), kanye ne-Styrene(PS) iyi-copolymer yezingxenye ezintathu, ehlanganisa izinzuzo zokusebenza zezingxenye ezintathu. Kuyinto "eqinile, eqinile futhi eqinile" enezinto zokusetshenziswa ezitholakala kalula, intengo eshibhile, ukusebenza kahle kanye nezinhlobonhlobo zokusetshenziswa. Inokushisa okuhle kakhulu nokubanda.
I-ABS kulula kakhulu ukuyicubungula. Ingakhiwa ngezindlela ezihlukahlukene zenqubo ezifana nomjovo, i-extrusion, ne-thermoforming; ingacutshungulwa ngokusaha, ukubhoboza, ukufaka, ukugaya, njll.; ingahlanganiswa nezincibilikisi eziphilayo ezifana ne-chloroform; kungase futhi kufuthwe, umbala, electroplated, kanye nezinye zokwelapha surface.
Embonini yamathoyizi, isibonelo esidume kakhulu sohlelo lokusebenza lwe-ABS yi-LEGO.
