Amapulasitiki aluhlaza emikhakheni ehlukene yokusetshenziswa

Njengoba ubuchwepheshe buqhubeka nokuthuthuka,ipulasitiki yobunjiniyelakancane kancane ziye zaba ukwaziswa okubalulekile ezimbonini ezihlukahlukene emkhakheni wesayensi yezinto zokwakha.Lesi sihloko sizocubungula izici, ukuhlukaniswa, izinqubo zokukhiqiza, kanye nokusetshenziswa okubanzi kwamapulasitiki obunjiniyela, kwembula izici ezingaqondakali zale sayensi yezinto.

I-Concept and Characteristics of Engineering Plastics Engineering amapulasitiki angamapulasitiki asebenza kahle kakhulu anezakhiwo ezinhle kakhulu zemishini, ukuqina kwamakhemikhali, nokumelana nezinga lokushisa eliphezulu.Uma kuqhathaniswa namapulasitiki ajwayelekile, akhombisa amandla aphakeme, ukuqina, nokumelana nokushisa, okuwenza agqame emikhakheni eyahlukene yobunjiniyela.

Ukuhlelwa Kwepulasitiki Yobunjiniyela

Amapulasitiki asebenza kahle kakhulu: njenge-polyamide (PAI) kanye ne-polyetheretherketone (PEEK), aziwa ngokuzinza kwawo okuvelele kwezinga lokushisa eliphezulu namandla, asetshenziswa kakhulu endaweni yezindiza, ezezimoto, nakwezinye izimboni.
Ubunjiniyela be-thermoplastics: njenge-polystyrene (PS) kanyei-polycarbonate (PC), enokucutshungulwa okuhle nokusebenza okuphelele, isetshenziswa kabanzi ku-electronics, imithi, nakweminye imikhakha.
Amapulasitiki e-thermosetting yobunjiniyela: okuhlanganisa ama-epoxy resins nama-phenolic resins, aziwa ngezakhiwo zawo ezinhle kakhulu zemishini kanye nokumelana nokushisa okuphezulu, okuvame ukusetshenziswa emishinini kagesi kanye nokukhiqizwa kwezingxenye zezimoto.
Ama-elastomers wobunjiniyela: njengei-polyurethane (PU)kanye nama-thermoplastic elastomers (TPE), anenani ngenxa yokunwebeka kwawo okuhle nokumelana nokugqokwa, asetshenziswa kakhulu emikhakheni yezimoto nemishini yezemidlalo.
Inqubo Yokukhiqiza Yepulasitiki Yobunjiniyela Ukwenziwa koplastiki bobunjiniyela ngokuvamile kuhilela ukulungiswa kwempahla eluhlaza, ukufudumeza nokuncibilika, nokukhipha noma ukubumba umjovo.Ukukhiqizwa kwamapulasitiki asebenza kahle kakhulu kuyinkimbinkimbi, kudinga ukulawulwa okuqinile kwenqubo kanye nemishini ethuthukisiwe.Ukuqamba okusha okuqhubekayo ezinqubweni zokukhiqiza kuthinta ngokuqondile ukusebenza kanye nekhwalithi yemikhiqizo yepulasitiki yobunjiniyela.

Izicelo ze-Engineering Plastics emikhakheni Ehlukahlukene

I-Aerospace: Oplastiki bobunjiniyela badlala indima ebalulekile emkhathini, ngepulasitiki esebenza kahle kakhulu i-PEEK esetshenziselwa ukwakha izingxenye zenjini yendiza, okuthuthukisa izinga lokushisa eliphezulu nokugqwala kwazo.

Ukukhiqizwa kwezimoto: Amapulasitiki obunjiniyela asetshenziswa kakhulu ekukhiqizeni izimoto, kusukela ezingxenyeni zangaphakathi kuya emabhokisini enjini, njenge-PC ne-PA, ehlisa kakhulu isisindo semoto futhi athuthukise ukusebenza kahle kukaphethiloli.

I-elekthronikhi nenkundla kagesi: Amapulasitiki wobunjiniyela asebenza izindima ezibalulekile kumishini kagesi kanye nekagesi, ahlinzeke ngokufaka inzalo, ukumelana nomlilo, neminye imisebenzi.Amapulasitiki afana ne-PC ne-PBT asetshenziswa kakhulu ezindlini ze-elekthronikhi nezixhumi.
Ukwenziwa kwemishini yezokwelapha: I-biocompatibility yamapulasitiki obunjiniyela iwenza abe yisinqumo esifanelekile sokwenziwa kwemishini yezokwelapha.Isibonelo, i-polycarbonate (i-PC) isetshenziselwa ukukhiqiza ama-casings edivaysi yezokwelapha esobala futhi ehlala isikhathi eside.

Ubunjiniyela bokwakha: Ukusetshenziswa kwamapulasitiki obunjiniyela kwezobunjiniyela bokwakha kugxile kakhulu ekumelana nesimo sezulu, ukumelana nokugqwala, nezinye izici.Amapulastiki afana ne-PVC ne-PA asetshenziswa kumapayipi, izinto zokufakelwa, nokunye.
Amathrendi Okuthuthukisa Ikusasa Lobunjiniyela Bepulasitiki

Ukuthuthukiswa okusimeme: Ukuthuthukiswa kwesikhathi esizayo kobunjiniyela bepulasitiki kuzogcizelela ukusimama, okuhlanganisa nokuthuthukisa ukusebenza kokucekelwa phansi nokucwaninga ukuphinda kusetshenziswe kabusha ukuze kuncishiswe umthelela wendawo.

Ukusebenza okuthuthukisiwe: Ngokuthuthuka kwezobuchwepheshe, amapulasitiki obunjiniyela azogxila ekuthuthukiseni ukuzinza kwezinga lokushisa eliphezulu, amandla, nezinye izakhiwo ukuze kuhlangatshezwane nezidingo zobunjiniyela eziguqukayo.

Izinhlelo zokusebenza ezihlakaniphile: Amapulasitiki wobunjiniyela kulindeleke ukuthi abambe iqhaza elikhulu ezinhlelweni zokusebenza ezihlakaniphile ngokuzayo, njengokwenza amapulasitiki obunjiniyela ahlakaniphile anemisebenzi yokuzwa yokuqapha isimo sezempilo sesakhiwo.

Ngaphezu kwalokho, ipulasitiki yobunjiniyela isetshenziselwaama-conveyor rollers(I-gravity roller） kufaka phakathi i-polyethylene (PE), i-polypropylene (PP), ne-nylon (PA), phakathi kokunye.Uma kuqhathaniswa nendabukoamarola ensimbi,  ama-roller epulasitiki babe umehluko olandelayo:

Isisindo:Amarola epulasitikizilula kuneamarola ensimbi, okufaka isandla ekwehliseni isisindo sisonke somthumeli, ukusetshenziswa kwamandla, kanye nokusebenza kahle komthumeli.

Ukumelana nokugqoka: Amarola epulasitiki ngokuvamile anokumelana okuhle nokugqokwa, anciphisa ukungqubuzana neibhande lokuthuthakanye nokwandisa isikhathi sabo sokuphila.

Ukumelana nokugqwala: Izinto zepulasitiki zobunjiniyela zinokumelana nokugqwala okuhle kakhulu, zilungele ukusetshenziswa ezindaweni ezinomswakama noma ezigqwalile.

Ukusimama: Izinto ezisetshenziswayo zamarola epulasitiki zingaphinda zisetshenziswe futhi zisetshenziswe kabusha, zihambisane nemigomo yentuthuko esimeme kanye nokuzuzisa imvelo.

Ukuncishiswa komsindo: Amarola epulasitiki avame ukuba nokumuncwa okuhle kokushaqeka kanye nemiphumela yokunciphisa umsindo, athuthukisa ukunethezeka kokusebenza kwesithuthi.

Kubalulekile ukukhetha izinto ezifanele ze-roller ngokusekelwe ezimweni ezithile zokusetshenziswa kanye nezidingo zokuqinisekisa ukuzinza nokusebenza ngempumeleloamasistimu okuthutha.

Njengomuntu ohamba phambili emkhakheni wesayensi yezinto zokwakha, ukusetshenziswa okusabalele kobunjiniyela bepulasitiki kuzo zonke izimboni ezahlukahlukene kugcizelela indima yabo ebalulekile kubunjiniyela besimanje.Njengoba ubuchwepheshe buthuthuka njalo, amapulasitiki obunjiniyela alungele indawo yokuthuthukiswa ebanzi, ehlinzeka ngezixazululo zempahla enokwethenjelwa nezisebenza kakhulu kumaphrojekthi wobunjiniyela kuyo yonke imikhakha.
