1. Incazelo yepulasitiki:
Ipulasitiki yinto ene-polymer ephezulu njengengxenye eyinhloko. Iqukethe i-resin yokwenziwa kanye nokugcwaliswa, ama-plasticizers, ama-stabilizers, ama-lubricants, ama-pigment nezinye izithasiselo. Kusesimweni soketshezi ngesikhathi sokukhiqiza nokucubungula ukwenza kube lula ukumodeliswa, Iveza isimo esiqinile lapho ukucubungula kuqediwe. Ingxenye eyinhloko yepulasitiki yi-resin yokwenziwa. "I-Resin" ibhekisa kupolymer yamangqamuzana aphezulu engahlanganisiwe nezithasiselo ezahlukahlukene. I-resin ibalelwa ku-40% kuya ku-100% wesisindo esiphelele sepulasitiki. Izici eziyisisekelo zamapulasitiki ikakhulukazi zinqunywa izakhiwo ze-resin, kepha izithasiselo nazo zidlala indima ebalulekile.
2. Izizathu zokuguqulwa kwepulasitiki:
Okubizwa ngokuthi "ukuguqulwa kwepulasitiki" kusho indlela yokwengeza into eyodwa noma ngaphezulu ku-resin yepulasitiki ukushintsha ukusebenza kwayo kwasekuqaleni, ukuthuthukisa into eyodwa noma ngaphezulu, bese ngaleyo ndlela kufezekiswe inhloso yokwandisa ububanzi bayo bokusebenzisa. Izinto zepulasitiki eziguquliwe ngokuhlanganyela zibizwa ngokuthi "amaplastiki aguquliwe".
Ukuguqulwa kwepulasitiki kubhekisa ekushintsheni izakhiwo zezinto zepulasitiki ohlangothini olulindelwe ngabantu ngokusebenzisa izindlela zomzimba, zamakhemikhali noma zombili izindlela, noma ukunciphisa kakhulu izindleko, noma ukwenza ngcono izakhiwo ezithile, noma ukunikeza amapulasitiki Umsebenzi omusha walokho okusetshenziswayo. Inqubo yokuguqula ingenzeka ngesikhathi se-polymerization ye-resin yokwenziwa, okungukuthi, ukuguqulwa kwamakhemikhali, njengokuhlanganiswa kwe-copolymerization, ukuxhumanisa, ukuxhumanisa, njll., Kungenziwa futhi ngesikhathi sokucubungula i-resin yokwenziwa, okungukuthi, ukuguqulwa komzimba, ukugcwalisa kanye nokubambisana kwe-polymerization. Ukuxuba, ukuthuthukisa, njll.
Izinhlobo zezindlela zokuguqulwa kwepulasitiki:
I-1) Ukuqinisa: Inhloso yokwandisa ukuqina namandla kwento kutholakala ngokungeza okugcwalisa imicu noma i-flake njenge-fiber fiber, i-carbon fiber, ne-mica powder, njenge-fiber fiber eqinisiwe ye-nylon esetshenziswa kumathuluzi kagesi.
2) Toughening: Inhloso yokwenza ngcono ukuqina namandla omthelela wepulasitiki kutholakala ngokungeza i-raber, i-thermoplastic elastomer nezinye izinto kupulasitiki, njenge-polypropylene ethintekayo evame ukusetshenziswa ezimotweni, imishini yasendlini kanye nokusetshenziswa kwezimboni.
3) Ukuxuba: ngokufanayo hlanganisa izinto ezimbili noma ngaphezulu ezingahambisani ngokuphelele nezinto zepolymer zibe ingxube ehambelana ne-macro-ehambisanayo nehlukaniswe isigaba ukuze ihlangabezane nezidingo ezithile ngokuya ngezakhiwo zomzimba nezomshini, izakhiwo ezibonakalayo, nezakhiwo zokucubungula. Indlela edingekayo.
4) Ukugcwalisa: Inhloso yokwenza ngcono izakhiwo zomzimba nezomshini noma ukunciphisa izindleko kutholakala ngokungeza okugcwalisa kupulasitiki.
5) Okunye ukuguqulwa: njengokusebenzisa izinto zokugcwalisa ukwehlisa ukumelana kagesi kwepulasitiki; ukwengezwa kwama-antioxidants kanye ne-stabilizers elula yokuthuthukisa ukumelana nesimo sezulu kwento leyo; ukwengezwa kwezingulube nodayi ukushintsha umbala wento leyo; ukwengezwa kwezigcobi zangaphakathi nezangaphandle zokwenza okokusebenza Ukusebenza kokucubungula kwepulasitiki eyisi-crystalline kuyathuthukiswa; i-ejenti ye-nucleating isetshenziselwa ukuguqula izici ze-crystalline zepulasitiki eyisi-crystalline ukuthuthukisa izakhiwo zayo zemishini ne-optical.
