Ziziphi izinto zemveliso zeplastiki?
Iimveliso zePlastiki zihlulwe kakhulu zibe ziintlobo ezimbini ze-thermoplastic kunye ne-thermosetting, oku kulandelayo kukwaziswa okucacileyo, ndiyathemba ukunceda.
1. Thermoplastic
I-Thermoplastics, eyaziwa ngokuba yi-thermoplastic resins, lolona didi luphambili lweeplastiki.Zenziwe ngezinto zokwenziwa zepolymer ezinokuqukuqela omnye komnye ngokunyibilika ngobushushu kwaye zikwazi ukunyanga kwakhona.Ezi zixhobo ngokuqhelekileyo zinobunzima obuphezulu be-molecular kwaye zine-repetitive ye-molecular chain structure.I-Thermoplastics inokucutshungulwa ngokubumba inaliti, i-extrusion, i-blow molding, i-calendering kunye nezinye iinkqubo ukwenza iinxalenye kunye neemveliso zeemilo ezahlukeneyo kunye nobukhulu.
(1) I-Polyethylene (PE) : I-PE yenye yeeplastiki eziqhelekileyo, ezisetyenziselwa ukupakisha, iipayipi, i-insulators yocingo kunye nezinye iinjongo.Ngokwesakhiwo sayo se-molecular kunye nobuninzi, i-PE inokwahlulwa ibe yi-polyethylene ephezulu (HDPE), i-polyethylene ephantsi (LDPE) kunye ne-linear low density polyethylene (LLDPE).
I-Polypropylene (PP) : I-PP nayo iplastiki eqhelekileyo, esetyenziswa ngokuqhelekileyo kwiibhotile, iibhotile kunye nezixhobo zonyango.I-PP yiplastiki ye-semi-crystalline, ngoko yomelele kwaye icace ngakumbi kune-PE.
(3) I-Polyvinyl chloride (PVC) : I-PVC yenye yezona mveliso ziphakamileyo zehlabathi zeplastiki, ezisetyenziswa ngokubanzi kwizinto zokwakha, i-insulators yocingo, ukupakishwa kunye nezixhobo zonyango kunye nezinye iinkalo.I-PVC inokuba nemibala kwaye iyaxhathisa kwiikhemikhali ezininzi.
(4) I-Polystyrene (PS) : I-PS isetyenziswa ngokuqhelekileyo ukwenza izinto zokupakisha ezilula, ezicacileyo, ezifana nezitya zokutya kunye neebhokisi zokugcina.I-PS ikwasetyenziswa ngokubanzi ukwenza amagwebu, njenge-EPS foam.
I-Acrylonitrile-butadiene-styrene copolymer (ABS) : I-ABS yiplastiki eqinile, i-impembelelo-resistant-resistant isetyenziswe ngokuqhelekileyo ukwenza izixhobo zokuphatha izixhobo, izindlu zombane, kunye neendawo zemoto.
(6) Abanye: Ukongezelela, kukho ezinye iintlobo ezininzi ze-thermoplastics, ezifana ne-polyamide (PA), i-polycarbonate (i-PC), i-polyformaldehyde (i-POM), i-polytetrafluoroethylene (PTFE) kunye nokunye.
2, iplastiki ye-thermosetting
Iiplastiki ze-Thermosetting yiklasi ekhethekileyo yeeplastiki, eyahlukileyo kwi-thermoplastics.Ezi zixhobo azithambi kwaye zihamba xa zishushu, kodwa zinyangwa bubushushu.Iiplastiki ze-Thermosetting zidla ngokuba namandla aphezulu kunye nokuqina kwaye zifanelekile kwizicelo ezifuna ukuqina okukhulu kunye namandla.
I-Epoxy resin (EP) : I-Epoxy resin yiplastiki eqinile ye-thermosetting esetyenziswa kakhulu kulwakhiwo, umbane kunye noshishino lweemoto.I-epoxy resins inokusabela kwikhemikhali kunye nezinye izinto ukwenza izinto ezincamathelayo ezinamandla kunye neengubo.
(2) I-Polyimide (PI) : I-Polyimide yiplastiki enokumelana nokushisa kakhulu enokugcina iimpawu zayo kumaqondo aphezulu.Isetyenziswa kakhulu kwi-aerospace, i-electronics kunye nemizi-mveliso yeemoto ukwenza izinto ezinokumelana nobushushu obuphezulu kunye neengubo.
(3) Abanye: Ukongezelela, kukho ezinye iintlobo ezininzi zeeplastiki ze-thermosetting, ezifana ne-phenolic resin, i-furan resin, i-polyester engaxutywanga kunye nokunye.
