I-Polyoxymethylene (POM) Resin: Itshe Lekona Elisebenza Kakhulu Elivuselela Ukukhiqiza Kwezimboni
Ukuhlaziywa Kokusebenza: Izakhiwo Ezivelele Zinika Izinzuzo Ezihlukahlukene
Amandla Angavamile Okusebenza Kwemishini
Amandla Okudonsa: 60–70 MPa, okuqhathaniswa nezinye izinto zensimbi, okuqinisekisa ukumelana nokuguquguquka ngaphansi kokucindezeleka okuphezulu.
I-Gonding Modulus: 2.5–3.0 GPa, enikeza ukwesekwa okuqinile kwesakhiwo sezingxenye ezithwala umthwalo.
Ukumelana Nokugqokwa: I-coefficient ephansi yokungqubuzana (0.1–0.3 ngaphansi kokungqubuzana okomile) yenza kube kuhle kakhulu ezingxenyeni ezishelelayo/ezijikelezayo njengegiya, ama-pulley, nama-sprocket, okunciphisa ukuguguleka nokwandisa isikhathi sokuphila kwemishini.
Ukumelana Nokukhathala: Imelana nezigidi zemijikelezo yokucindezeleka ejikelezayo ngaphandle kokwehluleka, ifanele izingxenye ezifakwa ekumisweni njalo noma ekulayishweni okuvamile.
Ukuqina Kwamakhemikhali Okuhle Kakhulu
I-POM imelana nezinyibilikisi eziphilayo, uwoyela, ama-asidi abuthakathaka, nama-alkali, igcina ubuqotho ezindaweni eziyinkimbinkimbi zamakhemikhali. Isibonelo, ezindaweni zenjini yezimoto, izingxenye ze-POM (isb., amagiya epompo kaphethiloli) zibekezelela uwoyela wemoto, i-coolant, kanye namazinga okushisa aphezulu ngaphandle kokuvuvukala noma ukugqwala. Kodwa-ke, ingase yonakale ngaphansi kwezimo ezimbi kakhulu zama-asidi aqinile, ama-alkali, noma umswakama okushisa okuphezulu.
Ukusebenza Okuthembekile Kokushisa
Izinga Lokushisa Eliphansi: 136–162°C (ngaphansi komthwalo we-0.45 MPa), kanye nokushisa kokusetshenziswa okuqhubekayo okungu-85–105°C, okulungele ukusetshenziswa okudinga ukumelana nokushisa okumaphakathi.
Ukushisa Okuphansi: 0.22–0.35 W/(m·K), okunikeza izakhiwo zokuvikela ukushisa zokuphathwa kokushisa kumadivayisi kagesi.
Ukufakwa Kokushisa Okuphezulu Kagesi
Ukumelana Nomthamo: 10¹³–10¹⁴ Ω·cm, ene-dielectric constant engu-3.7–3.9 (ku-1 MHz), igcina ukusebenza okuzinzile kokushisa kuzo zonke izigaba zokushisa/zomswakama kanye nama-frequency band.
Izicelo: Ilungele izingxenye zikagesi ezifana namaswishi, amabhlogo e-terminal, kanye nezindawo zokugcina zikagesi, okunciphisa izingozi zokuvuza noma izifunda ezimfushane.
Ukucutshungulwa Okuguquguqukayo
Ukuncibilika okuhle kakhulu kwe-POM kwenza kube lula ukwenziwa ngendlela enembile ngokubumba nge-injection molding, extrusion, blowing molding, njll., ngezikhathi zomjikelezo ezimfushane kanye nokusebenza kahle okuphezulu. Lokhu kuyenza ifaneleke ezingxenyeni eziyinkimbinkimbi ezikhiqiza ngobuningi, ihlangabezane nesidingo sezimboni esisheshayo.
Izinkambu Zokusebenza: Ukungena Okubanzi Okuqhubekisela Phambili Ukusungula Izinto Ezintsha Kwezimboni
Imboni Yezimoto: Ukusekelwa Okuthembekile Kwezingxenye Ezibalulekile
Uhlelo Lwenjini: Amagiya epompo kaphethiloli enziwe nge-POM aqinisekisa ukusebenza okuzinzile ngaphansi kwezimo zikaphethiloli ezinomfutho ophezulu, ngenxa yokungqubuzana okuphansi, ukumelana nokuguguleka, kanye nokuqina kwamakhemikhali, okuvumela ukulethwa kukaphethiloli okunembile.
Uhlelo Lwangaphakathi: Izibambo zeminyango, amagiya okulawula amafasitela, kanye nezingxenye zokulungisa izihlalo zisebenzisa amandla okusebenza e-POM ukuze kusebenze kahle futhi kuhlale isikhathi eside, kuyilapho ukucutshungulwa kwayo kuvumela amathuba ahlukahlukene okuklama.
Uhlelo Lokudlulisa: Ama-pulleys nama-sprocket esikhathi enziwe nge-POM adlulisa amandla ngempumelelo ngokulahlekelwa amandla okuncane.
Izinto zikagesi kanye nezinto zikagesi: Ukusekelwa Okubili Kokusebenza Nokuphepha
Izindawo Zokuhlala Zedivayisi: I-POM inikeza isivikelo esiqinile sama-electronics angaphakathi ngenkathi iqinisekisa ukuvikelwa kukagesi (isb., ama-fan blades namafreyimu ezinhlelweni zokupholisa zekhompyutha, okugcina ukuzinza ngesivinini esiphezulu ngaphandle kokuphazamisa izingxenye).
Izixhumi: Izingxenye ze-POM zinikeza ukunemba okuphezulu kanye nokuthembeka, okubalulekile ekugcineni ukuzinza kokuxhumana kukagesi ezixhumini.
Imishini Nemishini Yezimboni
Izingxenye Zemishini: Amagiya, ama-bushing, nama-bearings emishinini yezimboni azuza ekumelaneni nokuguguleka kwe-POM nomsindo ophansi, okunciphisa izidingo zokulungisa nokuthuthukisa ukusebenza kahle.
Amavalvu namaphampu: I-POM isetshenziswa kumaphampu amakhemikhali nama-valve ngenxa yokumelana kwayo nokugqwala, ifanele ukuthutha uketshezi olungagqwali ezimbonini zemithi nezokudla.
Izimpahla Zabathengi kanye Nezinsimbi Zokucacisa
Imikhiqizo Yabathengi: Ama-zipper, amagiya ewashi, kanye nezingxenye zemishini yasekhishini (isb., amagiya e-blender) asebenzisa i-POM ngenxa yokuqina kwayo kanye namakhono ayo okubumba ngobuhle.
Izinsimbi Zokucacisa: Kumadivayisi ezokwelapha kanye nemishini yokukhanya, ukunemba okuphezulu kanye nokuqina kwe-POM kuqinisekisa ukusebenza okuthembekile ezingxenyeni ezifana nama-syringe plunger kanye nama-lens mounts.

Ukusimama: Amazinga angasetshenziswa kabusha (izinga lokusebenzisa kabusha ngemva kwezimboni ≥90%) kanye nokukhiqizwa kwekhabhoni ephansi (ukusetshenziswa kwamandla okungaphansi kuka-15% uma kuqhathaniswa nesilinganiso semboni).
Ukuthobela Umthetho Komhlaba Wonke: Kuqinisekiswe yi-ISO 9001, i-FDA (ukuxhumana kokudla), kanye ne-RoHS/REACH yama-elekthronikhi, ngokulethwa okusheshayo (amasonto ama-2-4 emhlabeni jikelele).
Ubunjiniyela Bokushayela Injini Ukuqamba Amapulasitiki
Kusukela ezingxenyeni ezibalulekile zezimoto kuya ku-elekthronikhi enembile, i-POM resin iyaqhubeka nokuchaza kabusha lokho okungafezwa yipulasitiki yobunjiniyela. Inhlanganisela yayo eyingqayizivele yokuqina kwemishini, ukuqina kwamakhemikhali, kanye nokuguquguquka kwenqubo kuyenza ibe yinto ebalulekile kuzo zonke izimboni. Khetha i-POM yethu ukuze uvule ukuthembeka, ukusebenza kahle, kanye nokusungula izinto ezintsha—lapho yonke ingxenye iyibufakazi bokuhlanganiswa kokusebenza kwepulasitiki kanye nokuqina kwensimbi.
