I-Polyoxymethylene (POM) Resin: I-High-Performance Cornerstone Evuselela Ukukhiqiza Kwamabubulo
Ukuhlaziywa kokusebenza: Izakhiwo ezihle khulu zivumela iinzuzo ezihlukahlukeneko
Amandla wemitjhini angakavami
Amandla wokuthamba: 60-70 MPa, afana nezinye izinto zensimbi, ukuqinisekisa ukujamelana nokuguquguquka ngaphasi kokugandeleleka okukhulu.
I-Bending Modulus: 2.5–3.0 GPa, enikela ngokusekelwa okuqinileko kwesakhiwo seengcenye ezithwala umthwalo.
Ukujamelana nokuguga: I-coefficient ephasi yokutjhayisana (0.1–0.3 ngaphasi kokutjhayisana okomileko) yenza bona ibe yinto elungele ukutjhelela/ukujikeleza iingcenye ezifana namagiya, amapuleyi, nama-sprockets, ukwehlisa ukuguga nokwandisa isikhathi sokuphila kwemitjhini.
Ukujamelana nokudinwa: Ijamelana neengidigidi zemijikelezo yokugandeleleka ngaphandle kokuhluleka, ilungele iingcenye ezibekelwe ukuthoma-ukujama kanengi nofana ukulayishwa ngeenkhathi ezithileko.
Ukuzinza kwamakhemikhali okuhle khulu
I-POM ijamelana nezinto eziphilako, amafutha, ama-esidi abuthakathaka, nama-alkali, igcina ubuqotho eendaweni ezihlukahlukeneko zamakhemikhali. Ukwenza isibonelo, emagumbini weenjini zeenkoloyi, amalunga we-POM (isib., amagiya wepompo yamafutha) akghodlhelela amafutha weenkoloyi, isipholisi, kanye namazinga womtjhiso aphezulu ngaphandle kokuvuvuka nofana ukugqwala. Kodwana, ingawohloka ngaphasi kweemeko ezimbi khulu zama-esidi aqinileko, ama-alkali, nofana umswakama ophakemeko.
Ukusebenza kokutjhisa okuthembekileko
Izinga lokutjhisa lokutjhisa: 136–162°C (ngaphasi komthwalo we-0.45 MPa), ngezinga lokutjhisa lokusetjenziswa okuragela phambili kwe-85–105°C, elilungele ukusetjenziswa okutlhoga ukujamelana nokutjhisa okulinganiselweko.
Ukudlulisa ukutjhisa okuphasi: 0.22–0.35 W/(m·K), okunikela ngezakhiwo zokuvikela ukulawulwa kokutjhisa kumadivayisi we-elekthronikhi.
Ukuvikelwa kwegezi okuphezulu
Ukujamelana nomthamo: 1013–1014 Ω·cm, nge-dielectric constant ye-3.7–3.9 (ku-1 MHz), ukugcina ukusebenza okuzinzileko kokuvikela emazingeni amakhulu womtjhiso/umswakama kanye namabhendi wamafrikhwensi.
Iinsetjenziswa: Ilungele iingcenye zegezi ezifana namaswitjhi, amabhlogo wetheminali, kanye nezindlu ze-elekthronikhi, ukwehlisa ubungozi bokuvuza nofana amasekhethi amafitjhani.
Ukusetjenziswa okuhlukahlukeneko
Ukuncibilika okuhle khulu kwe-POM kwenza bona kwenziwe ngokunembileko ngokusebenzisa ukubumba ngokujova, ukukhipha, ukubumba ngokuphefumula, njll., ngesikhathi esifitjhani somjikelezo nokusebenza kuhle okukhulu. Lokhu kwenza bona ilungele ukukhiqiza ngobunengi iingcenye ezimile ezihlukahlukeneko, ukuhlangabezana nesidingo esirhabako sebubulo.
Iindawo zokusebenzisa: Ukungena okubanzi okutjhukumisela ukuThuthukiswa kwezebubulo
Ibubulo leenkoloyi: Ukusekela okuthembekileko kweengcenye eziqakathekileko
Irherho lenjini: Amagiya wepompo yephethiloli enziwe nge-POM aqinisekisa ukusebenza okuzinzileko ngaphasi kweemeko zephethiloli ezinomfutho omkhulu, ngebanga lokutjhayisana okuphasi, ukujamelana nokuguga, nokuzinza kwamakhemikhali, okwenza bona kube nokulethwa kwephethiloli ngokunembileko.
Irherho langaphakathi: Izibambo zeminyango, amagiya wokulawula amafasitela, kanye neengcenye zokulungisa isihlalo zisebenzisa amandla we-POM ukusebenza kuhle nokuhlala isikhathi eside, lokha ukusebenza kwayo kuvumela amathuba ahlukahlukeneko wokuklama.
Irherho lokudlulisa: Amapuli wesikhathi nama-sprockets enziwe nge-POM adlulisa amandla kuhle ngokulahlekelwa mandla okuncani.
Iinsetjenziswa ze-elekthronikhi nezegezi: Ukusekela okubili kokusebenza nokuphepha
Izindlu zedivayisi: I-POM inikela ngokuvikeleka okuqinileko kwe-elekthronikhi yangaphakathi ngesikhathi iqinisekisa ukuvikelwa kwegezi (isib., ama-feni blade namafreyimu eenhlelweni zokupholisa zekhomphyutha, ezigcina ukuzinza ngesivinini esikhulu ngaphandle kokuphazamisa iingcenye).
Iinhlanganisi: Iingcenye ze-POM zinikela ngokunemba okuphezulu nokuthembeka, okuqakathekileko ekugcineni ukunzinza kokuthintana kwegezi kumakhonktha.
Imitjhini yamabubulo neensetjenziswa
Iingcenye zemitjhini: Amagiya, amabhushi, kanye namabheringi wemitjhini yamabubulo azuza ngokujamelana nokuguga kwe-POM kanye nomsindo ophasi, ukwehlisa iindingo zokulondolozwa nokuthuthukisa ukusebenza kuhle.
Amavalvu namapompo: I-POM isetjenziswa emapompini wamakhemikhali namavalvu ukujamelana nokugqwala, ilungele ukuthutha amanzi angagqwala emabubulweni wemithi nokudla.
Iimpahla zabathengi kanye namaThulusi we-Precision
Imikhiqizo yabathengi: Amaziphu, amagiya wewatjhi, kanye namalunga wezinto zokusebenza ekhishini (isib., amagiya we-blender) asebenzisa i-POM ngokuqina kwayo kanye namakghono wokubumba ubuhle.
Iinsetjenziswa zokunemba: Eensetjenzisweni zezokwelapha neensetjenziswa zokubona, ukunemba okuphezulu nokuzinza kwe-POM kuqinisekisa ukusebenza okuthembekileko eengcenyeni ezifana nama-plunger wesirinji kanye nama-lens mounts.

Ukukhiqiza nokuqinisekiswa kwekhwalithi
Iinkambo zokukhiqiza
Ukwenza i-polymerization: Kwenziwa ngokusebenzisa i-cationic/anionic polymerization ye-formaldehyde, nge-stabilizers efakwe ukwenza ngcono ukuzinza kokutjhisa.
Ukuhlanganisa: Kuqiniswe ngefayibha yengilazi, ifayibha yekhabhoni, nofana amafutha wokuthambisa ukwenza izakhiwo (isib., i-POM ezele ingilazi ukuqinisa ukuqina nofana amagreyidi wokuzithambisa wokusebenzisa ukungqubuzana okuncani).
Amazinga wekhwalithi
Ukuhlolwa kwemitjhini: Amandla wokudonsa, ukunwebeka ngesikhathi sokuphuka, kanye nemodyuli yokugoba ehlolwe ngokuya nge-ISO 527 ne-ASTM D638.
Ukuhlolwa kokutjhisa: Izinga lokutjhisa lokutjhisa (HDT) kanye ne-melt flow index (MFI) elinganiswa nge-ISO 75 kanye ne-ASTM D1238.
Ukulawulwa kobumsulwa: Okuqukethwe kwensimbi ebudisi
Kubayini Sikhetha I-POM Resin Yethu?
Ukusebenza okusezingeni eliphezulu: I-POM yethu inikela ukuqina okufanako (75±5%) nokuqina kokudonsa (≥65 MPa), idlula amagreyidi ajwayelekileko ekujamelaneni nokudinwa (≥1 million cycles).
Iinsombululo ezikhethekileko: Amafomula alungiselelwe iindingo ezithileko:
Ukujamelana nokutjhisa okuphezulu: Amagreyidi atjhugululiweko wokusetjenziswa okuragela phambili kwe-120°C eenjinini zeenkoloyi.
Ukuvala ilangabi: amagreyidi ahambisana ne-UL 94 V-0 we-elekthronikhi.
Ukusimama: Amagreyidi angasetjenziswa kabutjha (izinga lokusetjenziswa kabutjha ngemva kwebubulo ≥90%) kanye nokukhiqizwa kwekhabhoni ephasi (15% ukusetjenziswa kwamandla okuncani nayiqathaniswa nesilinganiso sebubulo).
Ukuthobela iphasi loke: Kuqinisekiswe ku-ISO 9001, i-FDA (ukuthintana nokudla), kanye ne-RoHS/REACH yezinto ze-elekthronikhi, ngokulethwa msinyana (amaviki ama-2 ukuya kwamane ephasini loke).
Iinjini eziTjhayelako Ubunjiniyela bePlastiki
Kusukela eengcenyeni eziqakathekileko zeenkoloyi ukuya e-elekthronikhi eqondileko, i-POM resin iragela phambili nokuhlathulula kabutjha lokho amaplastiki wobunjiniyela angakwenza. Ukuhlanganiswa kwayo okuhlukileko kokuqina kwemitjhini, ukujamelana namakhemikhali, nokutjhuguluka kwenqubo kwenza bona ibe yinto eqakathekileko kizo zoke iimboni. Khetha i-POM yethu ukuvula ukuthembeka, ukusebenza kuhle, nokusungula—lapho woke amalunga atjengisa ukuhlanganiswa kokusebenza kweplastiki nokuqina kwensimbi.
