Umkhiqizi wezimoto e-Asia ushintshe izinto zendabuko ezilawula indawo yokungena enjini namavalvu okulawula uwoyela akhipha umoya, esikhundleni se-aluminium esebenzisa izinhlanganisela eziqiniswe nge-carbon fiber.
Le valve, eyenziwe ngezinto ezisezingeni eliphezulu ze-thermoplastic (kuye ngokuthi ubukhulu benjini, cishe ama-valve angu-2-8 ngemoto ngayinye), inciphisa kakhulu izindleko nesisindo sokukhiqiza imoto futhi ithuthukisa ukuphendula kwenjini.
I-2018 Septhemba 5-7th, i-Miami izosingatha i-American Association of Plastics Engineers Automotive Composites Conference (SPE Acce), izobonisa abantu uhlobo olusha lwe-resin olubizwa ngokuthi "Sumiploy CS5530", impahla ikhiqizwa yi-Sumitomo Chemical Company yaseTokyo, eJapane, Futhi inkampani inesibopho sokuthengisa emakethe yaseNyakatho Melika.
Izinhlayiya ze-Sumiploy zinefomula eyingqayizivele, eyenziwe ngokungezwa kwezintambo zekhabhoni eziqotshiwe nezithasiselo ku-PES resin ekhiqizwe yi-Sumitomo Corporation, ethuthukisa kakhulu ukumelana nemihuzuko kanye nokuzinza kwe-dimensional kwento. Kuthiwa le nhlanganisela inokumelana nokushisa okuhle kakhulu, ukuzinza okuhle kwe-dimensional kanye nokumelana nokukhuphuka okude kwebanga lokushisa elibanzi, amandla omthelela amahle, kanye nohlu lwezindawo ezinhle kakhulu ezifana nokumelana namakhemikhali kumakhompiyutha anuka kamnandi njengophethiloli, i-ethanol namafutha enjini, ukubambezeleka komlilo okungokwemvelo kanye nokumelana nokuqhekeka kwemvelo okuphezulu (ESCR).
Ngokungafani nezinye izinto eziningi ezisezingeni eliphezulu ze-thermoplastic, i-Sumiploy CS5530 inoketshezi oluningi, okwenza kube lula ukubumba amajiyometri e-3D anembe kakhulu. Ekusetshenzisweni okungokoqobo kwe-valve yokulawula, izinhlanganisela ze-Sumiploy CS5530 kufanele zihlangabezane nezidingo zobunjiniyela zokunemba kobukhulu obuphakeme kakhulu (10.7 mm±50 mm noma 0.5%), 40 ℃ kuya ku-150 ℃ ukuqina kwe-thermal, i-coefficient ephansi yokungqubuzana, ukumelana namakhemikhali ku-oyela nokukhathala okuhle kakhulu. Ukuguqulwa kwe-aluminium ibe yizinhlanganisela ze-thermoplastic akunciphisi nje kuphela izindleko zokukhiqiza, kodwa futhi kuthuthukisa kakhulu ukusebenza kanye nezindinganiso zokukhanya kwezinjini zezimoto. Kusukela yethulwa ngo-2015, ingxenye ibilokhu isetshenziswa kwezohwebo njengempahla ye-thermoplastic futhi ingaphinda isetshenziswe ngokuncibilika nokucutshungulwa kabusha.
Ngaphezu kwezinhlelo zokusebenza zezimoto, ama-Sumiploy resins nawo afaneleka kugesi/i-elekthronikhi kanye nezingxenye ze-aerospace ukuze zithathele indawo yensimbi eyenziwe ngomshini noma i-aluminium, kanye nezinye izinto ezisebenza kahle kakhulu ze-thermoplastic ezifana ne-PEEK, i-polyether ketone (PAEK), ne-Polyether imide (PEI). Nakuba lezi zinhlelo zokusebenza zingagxili ekunakeni kwethu, ama-sumiploy resins anciphisa ukungqubuzana ngezindawo ezifanayo endaweni yokumanzisa okuncane, kuyilapho ukuhlanganiswa kwezingxenye ezibunjwe ngomjovo onembe kakhulu kuthuthukisa ukusebenza kwempahla futhi kwehlisa izindleko zokukhiqiza. Ama-Sumiploy resins alungele ukushintsha izinsimbi kuma-valve pistons okulawula uwoyela, ama-solenoid valve pistons, ama-HVAC blades namapiston, kanye namagiya ezimboni, ama-bushing-free bushings nama-bearings.
