I-Polyoxymethylene (POM) Resin: Litje Lelisetulu Lelisebenta Kabusha Lelisungula Kukhicita Timboni
Kuhlatiya Kusebenta: Timphahla Letivelele Tinika Emandla Tinzuzo Letehlukahlukene
Emandla Emishini Langakavami
Tensile Emandla: 60–70 MPa, kucatsaniswa naletinye tintfo tensimbi, kucinisekisa kumelana nekugucuka ngaphansi kwekucindzeteleka lokusetulu.
Modulus yekugoba: 2.5–3.0 GPa, kuniketa kusekelwa lokucinile kwesakhiwo setincenye letithwala umtfwalo.
Kumelana nekugcoka: Kugcoka lokuphansi kwe coefficient (0.1–0.3 ngaphansi kwekugcoka lokomile) kwenta kutsi kube kuhle kakhulu kushelela/kujikeleta tincenye letifana nemagiya, ema pulleys, kanye nema sprockets, kunciphisa kugcoka kanye nekwelula sikhatsi sekuphila kwetintfo tekusebenta.
Kumelana nekudzinwa: Kumelana netigidzi temijikeleto yekucindzeteleka lokujikeletako ngaphandle kwekwehluleka, kulungele tincenye letibhekene nekucala-kuma njalo noma kulayishwa ngetikhatsi letitsite.
Kusimamisa Lokuhle Kakhulu Kwemakhemikhali
iPOM imelana netinhlayiya letiphilako, emafutsa, ema esidi labutsakatsaka, kanye ne alkalis, igcina bucotfo etindzaweni letiyinkimbinkimbi temakhemikhali. Sibonelo, emagumbini enjini yetimoto, tincenye te POM (sib., emagiya ephampu yaphethiloli) tibeketelela oyili wemoto, kupholisa, kanye nekushisa lokusetulu ngaphandle kwekuvuvuka noma kugcola. Nomakunjalo, ingahle yehle ngaphansi kwetimo letimbi kakhulu tema esidi lacinile, ema alkali, noma umswakama lonekushisa lokusetulu.
Kusebenta Kwekushisa Lokwetsembekile
Kushisa Kwekuphambuka Kwekushisa: 136–162°C (ngaphansi kwemtfwalo wa 0.45 MPa), ngekushisa kwekusebentisa lokuchubekako kwa 85–105°C, kulungele kusetjentiswa lokudzinga kumelana nekushisa lokulinganiselwe.
Kushisa Lokuphansi: 0.22–0.35 W/(m·K), kuniketa timphahla tekuvikela tekulawula kushisa kumadivayisi e-elekthronikhi.
Kuvikela kwagezi lokusezingeni lelisetulu
Kumelana Kwevolumu: 1013–1014 Ω·cm, nge dielectric lehlala njalo ye 3.7–3.9 (ku 1 MHz), kugcina kusebenta kwekuvikela lokucinile kuyo yonkhe imikhakha lebanti yekushisa/umswakama kanye nemabhande emvamisa.
Ticelo: Kulungele tincenye tagezi letifana nemaswitshi, emabhulokhi ekugcina, kanye netindlu te-elekthronikhi, kunciphisa bungoti bekuvuta noma emasekethe lamafishane.
Kucubungula lokuhlukahlukene
POM's enhle kakhulu kuncibilika fluidity kuniketa emandla fabrication ngqo nge umjovo kubumba, extrusion, blow kubumba, njll, nge tikhatsi emjikeleto emfushane kanye nekusebenta kahle lokusezingeni leliphakeme. Loku kwenta kutsi ilungele kukhicita ngebunyenti tincenye letimise ngendlela leyinkimbinkimbi, kuhlangabetana nesidzingo lesisheshako setimboni.
Tinsimu Tesicelo: Kungena Lokubanti Kushayela Kusungulwa Kwetimboni
Imboni Yetimoto: Kusekelwa Lokutsembekile Kwetincenye Letibalulekile
Luhlelo Lwenjini: Emagiya ephampu yaphethiloli lentiwe nge-POM acinisekisa kusebenta lokucinile ngaphansi kwetimo tephethiloli letinemfutfo lomkhulu, sibonga kukhuhlana lokuphansi, kumelana nekugcoka, kanye nekusimama kwemakhemikhali, kwenta kutsi kuhanjiswe phethiloli ngalokucondzile.
Luhlelo lwangekhatsi: Tibambo temnyango, emagiya ekulawula emafasitelo, kanye netincenye tekulungisa situlo tikhutsata emandla emishini ye-POM kute isebente kahle futsi icinise, kantsi kucubungula kwayo kuvumela ematfuba lahlukahlukene ekuklama.
Luhlelo Lwekudlulisela: Timing pulleys kanye sprockets lentiwe POM kahle kudlulisela emandla ngekulahlekelwa emandla kancane.
Tintfo Tegezi Netintfo Tagezi: Kusekelwa Lokubili Kwekusebenta Nekuphepha
Tindlu Temadivayisi: I-POM iniketa kuvikeleka lokucinile kwe-elekthronikhi lengekhatsi ngesikhatsi icinisekisa kuvikeleka kwagezi (sib., ema-fan blades kanye nemafreyimu etinhlelo tekupholisa emakhompyutha, lagcina kusimamisa ngesivinini lesikhulu ngaphandle kwekuphazamisa tincenye).
Tihlanganisi: Tincenye te-POM tiniketa kuciniseka lokusezingeni leliphakeme kanye nekwetsembeka, lokubalulekile ekugcineni kusimama kwekuchumana kwagezi etihlanganisi.
Imishini Nemishini Yetimboni
Tincenye Temishini: Emagiya, ema bushings, kanye nemabheringi emishinini yetimboni ayazuza ngekumelana nekugcoka kwe POM kanye nemsindvo lophansi, kunciphisa tidzingo tekunakekelwa kanye nekutfutfukisa kusebenta kahle.
Emavalvu nemaphampu: iPOM isetjentiswa kumaphampu emakhemikhali kanye nemavalvu ngekumelana kwayo nekugcola, ilungele kutfutsa emanti langagcobi etimbonini temisebenti yemitsi kanye nekudla.
Timphahla Tebatsengisi kanye Netintfo Tekusebenta Leticinile
Imikhicito Yebatsengisi: Zippers, emagiya ewashi, kanye netincenye tetintfo tasekhishini (sib., emagiya e-blender) asebentisa i-POM ngekucinisa kwayo kanye nemandla ekubumba ebuhle.
Tintfo tekusebenta letinembile: Emadivayisini ekwelapha kanye nemishini yekubuka, kuciniseka lokusezingeni leliphakeme kwe-POM kanye nekusimama kucinisekisa kusebenta lokutsembekile etincenyeni letifana nema-plungers e-syringe kanye nekubeka lens.

Kukhicita Nekucinisekisa Lizinga
Tinchubo Tekukhicita
Kuhlanganiswa: Kukhicitwa ngekuhlanganiswa kwe cationic/anionic kwe formaldehyde, ngetintfo leticinisako letingetiwe kwentela kwenta ncono kusimamisa lokushisako.
Kuhlanganisa: Kuciniswa nge fibre yengilazi, icarbon fibre, noma tintfo tekugcobisa kwentela kuhambisana netimphahla (sib., iPOM legcwele ingilazi kwentela kucina lokukhulisiwe noma emabanga latigcobisako kwentela kusetjentiswa lokuphansi kwekugcobisa).
Emazinga elizinga
Kuhlolwa kwemishini: Emandla ekucindzetela, kukhula ngesikhatsi sekuphuka, kanye nemojuli yekugoba lehlolwa nge ISO 527 kanye ne ASTM D638.
Kuhlolwa kwekushisa: Kushisa kwekuphambuka (HDT) kanye nenkomba yekugeleta kwekuncibilika (MFI) lokulinganiswa nge ISO 75 kanye ne ASTM D1238.
Kulawula Bumsulwa: Kucuketfwe kwensimbi lesindzako
Kungani Sikhetsa I-POM Resin Yetfu?
Kusebenta Kwekucala: I-POM yetfu iniketa i-crystallinity lehambisanako (75 ± 5%) kanye nemandla ekucindzeteleka (≥65 MPa), lehamba embili emabanga lajwayelekile ekumelaneni nekudzinwa (≥1 million imijikeleto).
Tisombululo Letikhetsekile: Emafomula lalungiselelwe tidzingo letitsite:
Kumelana Nekushisa Lokuphakeme: Emabanga laguculwe kwentela kusetjentiswa lokuchubekako kwa 120°C etinjinini tetimoto.
Kuvimbela Lilangabi: UL 94 V-0 emabanga lahambisana ne-elekthronikhi.
Kusimama: Emabanga laphindze asetjentiswe (lizinga lekuphindza asetjentiswe ngemuva kwekukhicita ≥90%) kanye nekukhicita lokuphansi kwekhabhoni (15% kusetjentiswa kwemandla kancane vs. silinganiso semboni).
Kuhambisana Kwemhlaba Wonkhe: Kucinisekisiwe ku ISO 9001, FDA (kutsintsana ngekudla), kanye ne RoHS/REACH yetintfo te-elekthronikhi, ngekuletsa ngekushesha (emaviki langu 2–4 emhlabeni wonkhe).
Kusungulwa Kwemapulasitiki Ebunjiniyela Bekushayela Injini
Kusuka etincenyeni letibucayi tetimoto kuya ku-elekthronikhi lecinisekile, i-POM resin iyachubeka nekuchaza kabusha kutsi yini emapulasitiki ebunjiniyela langayifeza. Kuhlanganiswa kwayo lokuhlukile kwekucina kwemishini, kucina kwemakhemikhali, kanye nekugucugucuka kwenchubo kwenta kutsi kube yintfo lebalulekile kuto tonkhe timboni. Khetsa i-POM yetfu kuvula kwetsembeka, kusebenta kahle, kanye nekusungula-lapho yonkhe incenye iyibufakazi bekuhlanganiswa kwekusebenta kwepulasitiki kanye nekucina kwensimbi.
