Iiplastiki zinokwahlulwa zibe ziiplastiki eziqhelekileyo, iiplastiki zobunjineli kunye neeplastiki ezikhethekileyo ngokusetyenziswa kwazo.Ngokohlelo lomzimba kunye neekhemikhali lunokwahlulwa kwiiplastiki ze-thermosetting, iiplastiki ze-thermoplastic zimbini iindidi;Ngokwendlela yokubumba ulwahlulo lunokwahlulwa lube kukubumba, ukulatyuza, inaliti, ukubunjwa kokuvuthela, i-extrusion, iplastiki yokuphosa kunye neplastiki yenaliti esebenzayo kunye nezinye iintlobo.I-1, iplastiki ngokubanzi: ihlala ibhekisa kwimveliso enkulu, ukusetyenziswa okubanzi, ukwakheka okuhle, iplastiki ephantsi.Kukho iindidi ezintlanu zeeplastiki eziqhelekileyo, ezizezi, i-polyethylene kunye ne-polypropylene.
1.iplastiki jikelele: ngokuqhelekileyo ibhekisela kwimveliso enkulu, ukusetyenziswa okubanzi, ukwakheka okulungileyo, iplastiki ephantsi.Kukho iintlobo ezintlanu zeeplastiki eziqhelekileyo, ezizezi i-polyethylene, i-polypropylene, i-polyvinyl chloride, i-polystyrene, i-acrylonitrile - i-butadiene - i-styrene copolymer.
2. iiplastiki zobunjineli: ziyakwazi ukumelana namandla athile angaphandle, zineempawu ezintle zoomatshini kunye nokumelana nokushisa okuphezulu kunye nokuphantsi, ukuzinza okuhle kwe-dimensional, kunokusetyenziswa njengesakhiwo sobunjineli beeplastiki, ezifana ne-polyamide, i-polysulfone, njl.
3. Iiplastiki ezikhethekileyo: Zibhekiselele kwiiplastiki ezinemisebenzi ekhethekileyo enokusetyenziswa kwi-aviation, i-aerospace kunye nezinye iindawo ezikhethekileyo zesicelo, ezifana neeplastiki ze-fluorine kunye ne-organic silicon.
4. I-Thermoplastic: ibhekisela kwiplastiki eya kunyibilika emva kokufudumeza, inokugeleza kwi-mold emva kokupholisa kunye nokwenza, kwaye iya kunyibilika kwakhona emva kokufudumeza;Ungasebenzisa ukufudumeza kunye nokupholisa ukwenza ukuguqulwa, yinto ebizwa ngokuba yinguqu yomzimba.
5. iiplastiki ze-thermosetting: zibhekisela phantsi kobushushu okanye ezinye iimeko ezinokunyanga kwaye zibe neempawu ezingenakunyibilika (ezinyibilikayo) zeeplastiki, ezifana neeplastiki ze-phenolic, iiplastiki ze-epoxy, njl.
I-6.iplastiki yoxinzelelo lwefilimu: uninzi lweepropathi ezibonakalayo zepropathi yokucubungula kunye neplastiki eqinile ngokubanzi efana neplastiki.
I-7.iplastiki ye-laminated: ibhekisela kwi-resin efakwe i-fiber fabric, i-composite, i-hot pressing kwaye idibaniswe kuyo yonke into.
8. inaliti, ukuvuthela ukubumba, iplastiki extrusion: uninzi lweempawu ezibonakalayo kunye neempawu processing kunye thermoplastic jikelele efanayo iplastiki.
I-9.Iplastiki yokuphosa: Ibhekisela kumxube we-resin ye-liquid, njenge-nylon ye-MC, enokuthi igalelwe kwi-mold kwaye iqiniswe kwiimveliso zemilo ethile phantsi koxinzelelo okanye uxinzelelo oluncinci.
10.ifanele ifakwe iplastiki: izinto eziluhlaza, i-injection yoxinzelelo kwi-membrane cavity, ukwenzela ukuba ukuphendula ukunyangwa kwimilo ethile yeemveliso zeplastiki, ezifana ne-polyurethane, njl.
