Polyoxymethylene (POM) Resin: Ibbwe lyakkona lichita obotu loko lipa kuti kube nzila zyakupanga zintu
Kuvwuntauzya Kubeleka: Zintu Zibotu Zipa Bubotu Bwiindene-indene
Nguzu Zyakubelesya Zintu Zipati
Nguzu zyakukwela: 60-70 MPa, kweelanisigwa azintu zimwi zyabutale, zipa kuti kutabi kuchincha muchiindi chakukatazyigwa kapati.
Kukotama: 2.5–3.0 GPa, kupa lugwasyo luyumu lwazibeela zinyamuna mikuli.
Kukazya kusama: Kukwabililwa kusyoonto (0.1–0.3 muchiindi chakubula nguzu) kupa kuti ube kabotu kuzyintu zizungaana/zizunguluka mbuli magiya, ma pulleys, ama sprockets, kuchesya kubola akuyungizya buumi bwazibelesyo.
Kukazya Kukatala: Kulakonzya kuliyumya mumamiliyoni aaziindi zyakukatazyigwa kakunyina kwaalilwa, kweelela kuzibeela zibelesyegwa kutalika-kwiima chiindi chiingi.
Kukkalilila Kwamakemikalu Kubotu
POM ilakazya zintu zipona, mafuta, asidi iitajisi nguzu, ama alkali, ikubamba kusyomeka mumasena aakatazya kumvwisisisya. Mbuli chitondeezyo, muma injini aamyootokala, zibeela zya POM (nkokuti, magiya aakupompa mafuta) zilakonzya kuliyumya mumafuta aamumootokala, maanzi aatontola, akupya kapati kakunyina kuzimba naa kubola. Nokuba boobo, ilakonzya kunyonyooka mubukkale bukatazya bwa asidi mpati, ma alkali, naa kupya kapati.
Kubeleka Kwakupya Kusyomeka
Kupya Kwakugwisya Kupya: 136–162°C (munsi aa 0.45 MPa), akubelesya kuzumanana kwa 85–105°C, kweelela kubelesyegwa muzintu ziyandika kukaka kupya.
Kuyungizya Kupya: 0.22–0.35 W/(m·K), kupa nguzu zyakukwabilila kupya muzibelesyo zyamagesi.
Kukwabilila magesi kubotu
Kukazya kwajwi: 1013–1014 Ω·cm, a dielectric constant ya 3.7–3.9 (a 1 MHz), kubamba mulimo wakukwabilila uutazungaani mumasena manji aakupya/kutontola alimwi ama frequency bands.
Kubelesegwa: Nchibotu kuzibelesyo zyamagesi zilimbuli swichi, ma terminal blocks, antoomwe amaanda aamagesi, kuchesya ntenda zyakuzwa kwamagesi naakuti kufwiinsya magesi.
Kubelesegwa munzila zyiingi
Bubotu bwa POM bwakunyengulula bupa kuti kube kupanga kabotu kwiinda mukubelesya nzila ya injection moulding, extrusion, blow molding, azimwi, kakuli chiindi chifwiifwi chakubeleka kabotu. Eezi zipa kuti ibeleke kupanga zibeela zyiingi zikatazya kumvwisisisya, ikuzuzikizya ziyandikana zyamakwebo.
Misyobo yakubelesya: Kunjilila Kupati Kusololela Kupanga Zintu Zipya Mumakkampani
Makwebo aakupanga myootokala: Lugwasyo lusyomeka lwazibeela ziyandikana
Nzila ya Injini: Magiya aakupompa mafuta aapangidwe a POM alasinizya kuti abelekela kabotu mubukkale bwamafuta aajisi nguzu kapati, akaambo kakuzwangana kusyoonto, kukazyigwa kusama, alimwi akukkalilila kwamakemikalu, calo cipa kuti mafuta azwe kabotu.
Nzila yamukati: Zijatizyo zyamilyango, magiya aabamba mawindo, antoomwe azibelesyo zyakubambulula zyuuno zibelesya nguzu zya POM kuti zibeleke kabotu akuyuma, mpawo kubelesegwa kwazyo kupa kuti kube nzila zyakupanga zintu ziindene-indene.
Nzila Yakutola: Zibelesyo zyakupima chiindi antoomwe ama sprockets zyakabambwa a POM zilatola manguzu kabotu kakunyina kusweekelwa manguzu masyoonto.
Zibelesyo zyamagesi azyamagesi: Lugwasyo lwachibili lwakuchita obotu akukwabililwa
Maanda aazibelesyo: POM ipa lukwabililo luyumu kuzibelesyo zyamukati zyamagesi mpawo kazikwabilila magesi (nkokuti, mabbaaji aafeni amafulemu muma kkompiyuta aatontola, alo aabamba kukkalikana muchiindi chifwiifwi kakunyina kunyonganya zibeela).
Ziswaanganya: Zibeela zya POM zipa kululama kupati akusyomeka, nchintu chipati mukubamba kujatana kwamagesi muzintu zijatikizya.
Minchina azibelesyo zyamafakitali
Zibeela zyaminchina: Magiya, mabbusu, amabbeya muzibelesyo zyamafakitali zilagwasyigwa a POM's kukaka kubola akucheya muzuzumo, kuchesya ziyandika zyakubambulula akusumpula bubotu bwakubeleka.
Mavalvu amapompi: POM ibelesyegwa mumapompi aamakemikalu amavalvu nkaambo kakutabola, ilakonzya kunyamuna maanzi aatabola mumakkampani aapanga misamu azyakulya.
Zintu Zyakuula azibelesyo Zyakubelesya Zibotu
Zintu Zyakuula: Zizipu, magiya aawotchi, azibeela zyazibelesyo zyakujika (nkokuti, magiya aa blender) zibelesya POM nkaambo kakuyuma kwayo akukonzya kubumbwa kabotu.
Zibelesyo Zyakubelesya Zilondokede: Muzibelesyo zyabusilisi azibelesyo zyakulanga, POM's kulondoka kupati akukkalwa moyo kupa kuti kube kubeleka kabotu muzibeela zilimbuli zibelesyo zya syringe antoomwe a lens mounts.

Kupanga akusinizya bubotu
Nzila Zyakupanga
Kuyungizya: Kuchitwa kwiinda mukubelesya nzila ya cationic/anionic polymerization ya formaldehyde, antoomwe azintu ziyumya-yumya zyayungizigwa kuti zikwabilile kupya.
Kusanganya: Kuyumizigwa agilazi, kkaboni, naakuti mafuta kuti abe kabotu (nkokuti, POM iizwide gilazi kuti iyungizye kuyuma naakuti ma grade aakulisakatizya aakubelesya kakunyina kutyompokelwa).
Zyeelelo zyaBubotu
Kusunkwa kwaminchina: Nguzu zyakukwela, kulampa kwachiindi chakutyoka, antoomwe akukotama kwakasunkwa kweendelanya a ISO 527 antoomwe a ASTM D638.
Kusunkwa kwakupya: Kupya kwakupya (HDT) antoomwe amweelwe wakunyenguluka (MFI) zyakapimwa kweendelana a ISO 75 antoomwe a ASTM D1238.
Kubamba Busalali: Bunji bwazibulo zilemu zili
Nkaambo nzi Ncotweelede Kusala POM Resin Yesu?
Kubeleka kabotu: POM yesu ilaa buvubi butazungaani (75±5%) akuyuma kwanguzu (≥65 MPa), kwiinda zyeelelo zyabuzubaa buzuba mukukazya kukatala (≥1 miliyoni yaziindi).
Nzila zyakumanizya mapenzi: Nzila zipangidwe kweendelana aziyandika zimwi:
Kukazya Kupya Kupati: Zibeela zyakasandulwa kuti zibelesyegwe a 120°C muinjini zyamyootokala.
Kukwabilila mulilo: UL 94 V-0 kweendelana ama grade aazibelesyo zyamagesi.
Kuzumanana: Zibeela zikonzya kubelesegwa lubo (mweelwe wakubelesya lubo musule lyamakkampani ≥90%) akupanga kaboni nsyoonto (15% kubelesya manguzu masyoonto kweelanisigwa amweelwe waakati-kati wamakkampani).
Kutobelezya munyika yoonse: Kwazumizigwa a ISO 9001, FDA (kuswaangana azyakulya), antoomwe a RoHS/REACH yazibelesyo zyamagesi, akutuminwa chakufwambaana (2-4 mvwiki nyika yoonse).
Injini Iyendelezya Injiniya Mapulasitiki Mapya
Kuzwa kuzibeela ziyandikana zyamumugwagwa kusikila kuzibelesyo zyamagesi, POM resin ilazumanana kusandula eezyo mapulasitiki aakonzya kuchitwa. Kusanganya kwayo kulibedelede kwakuyuma kwaminchina, kusima kwamakemikalu, akucinca-cinca kwanzila zipa kuti kibe chintu chiyandikana mumakkampani woonse. Sala POM yesu kuti ujalule kusyomeka, kubeleka obotu, akuchita zintu zipya—oomo zibeela zyoonse nkozitondezya kuswaangana kwakubeleka kwapulasitiki akuyuma kwabutale.
