Resin ya Polyoxymethylene (POM): Ibuye ry'inyuma rikora neza cyane rivugurura inganda
Isesengura ry'Imikorere: Imiterere Idasanzwe Ituma Haba Ibyiza Bitandukanye
Imbaraga zidasanzwe za mekanike
Ingufu zo Gukurura: 60–70 MPa, igereranywa n'ibikoresho bimwe na bimwe by'icyuma, bituma habaho ubudahangarwa bwo kwangirika kw'ingufu mu gihe cy'imbaraga nyinshi.
Modulus yo Kugonda: 2.5–3.0 GPa, itanga inkunga ikomeye y'imiterere y'ibice bitwara imizigo.
Ubudahangarwa bwo kwambara: Ingano nto yo kwambara (0.1–0.3 mu gihe cy’ingufu zumutse) ituma biba byiza mu guterera no kuzunguruka ibice nk’amagi, imipira, n’udupira, bigabanya kwambara no kongera igihe cyo kumara ibikoresho.
Ubudahangarwa bw'Umunaniro: Ihangana n'imizunguruko ya miliyoni z'imizunguruko idatsindwa, ikwiriye ibice bikunze guhagarara cyangwa gushyirwamo ibikoresho buri gihe.
Gukomera cyane mu bya shimi
POM irwanya ibintu bihumanya ikirere, amavuta, aside nke, na alkali, ikomeza kuba ingirakamaro mu bintu bigoye bikomoka ku binyabutabire. Urugero, mu bice bya moteri z'imodoka, ibice bya POM (urugero, ibikoresho bya pompe ya lisansi) bihangana n'amavuta ya moteri, icyuma gikonjesha, n'ubushyuhe bwinshi bidatumba cyangwa ngo bigire ingese. Ariko, ishobora kwangirika iyo hari aside ikomeye, alkali, cyangwa ubushyuhe bwinshi.
Imikorere yizewe y'ubushyuhe
Ubushyuhe bwo guhindagurika k'ubushyuhe: 136–162°C (munsi ya 0.45 MPa), hamwe n'ubushyuhe bwo gukoresha buri gihe bwa 85–105°C, bukwiriye gukoreshwa mu buryo busaba ubushyuhe buringaniye.
Ubushobozi bwo gutwara ubushyuhe buri hasi: 0.22–0.35 W/(m·K), butanga ubushobozi bwo gukingira ubushyuhe mu bikoresho by'ikoranabuhanga.
Ubwishingizi bw'amashanyarazi bwo mu rwego rwo hejuru
Ubushobozi bwo kwirinda ingano: 10¹³–10¹⁴ Ω·cm, ifite imiterere ya dielectric ya 3.7–3.9 (kuri 1 MHz), ikomeza imikorere ihamye yo gukingira mu bushyuhe bwinshi/ubushuhe n'imirongo y'impinduka.
Porogaramu: Ni nziza ku bikoresho by'amashanyarazi nka swichi, terminal blocks, n'ibikoresho by'ikoranabuhanga, bigabanya ibyago byo kuva cyangwa guhagarara k'amashanyarazi.
Uburyo bwo gutunganya ibintu butandukanye
Uburyo bwiza bwo gushonga bwa POM butuma ikorwa neza binyuze mu gusya, gusohora, gusya, nibindi, hamwe n'igihe gito cyo gukora kandi igakora neza cyane. Ibi bituma ikoreshwa mu gukora ibice byinshi bifite ishusho igoye, bigahura n'ibikenewe byihuse mu nganda.
Ahantu ho Gukoresha: Kwinjira mu buryo bwagutse bitera udushya mu nganda
Inganda z'imodoka: Inkunga yizewe ku bice by'ingenzi
Sisitemu ya moteri: Ibyuma bya pompe ya lisansi bikozwe muri POM bitanga imikorere ihamye mu gihe cy’umuvuduko mwinshi wa lisansi, bitewe n’uko nta gukururana gukomeye, kudashira kw’ingufu, no kudahinduka kw’imiti, bigatuma lisansi itangwa neza.
Sisitemu y'imbere: Imigozi y'inzugi, ibikoresho byo kugenzura amadirishya, n'ibikoresho byo guhindura intebe bikoresha imbaraga za POM kugira ngo bikore neza kandi birambe, mu gihe ubushobozi bwayo bwo kuyitunganya butanga amahirwe atandukanye yo kuyishushanya.
Sisitemu yo kohereza amakuru: Puli na sprockets bipima igihe bikozwe muri POM byohereza imbaraga neza kandi nta ngufu nyinshi zitakaza.
Ibikoresho by'ikoranabuhanga n'amashanyarazi: Inkunga ebyiri mu mikorere n'umutekano
Amazu yo gucumbikiramo ibikoresho: POM itanga uburinzi bukomeye ku bikoresho by'ikoranabuhanga by'imbere mu mubiri mu gihe igenzura ko amashanyarazi ashyirwa mu buryo butuje (urugero, ibyuma by'abafana n'amakaramu muri sisitemu zo gukonjesha za mudasobwa, bikomeza kugumana ubusugire ku muvuduko wo hejuru bitabangamiye ibice bigize ibikoresho).
Ibihuza: Ibice bya POM bitanga ubuziranenge n'ubwirinzi bwo hejuru, ni ingenzi cyane mu kubungabunga ubusugire bw'amashanyarazi mu miyoboro.
Imashini n'ibikoresho by'inganda
Ibice bigize ikoranabuhanga: Ibyuma, imigozi, n'amabati mu bikoresho by'inganda bigira uruhare mu kudashira kwa POM no kutagira urusaku ruhagije, bigabanya ibyo umuntu akeneye mu kubungabunga no kunoza imikorere.
Valves na Pompe: POM ikoreshwa mu ipompo za shimi n'udupira tw'imiti kubera ko irwanya ingese, ikaba ikwiriye gutwara amazi adahumanya ikirere mu nganda zikora imiti n'ibiribwa.
Ibicuruzwa by'Abaguzi n'Ibikoresho By'Uburyo Bw'ibanga
Ibicuruzwa by'abaguzi: Zipu, ibikoresho byo mu gikoni, n'ibikoresho byo mu gikoni (urugero: ibikoresho byo mu bwoko bwa blender) bikoresha POM kubera ubushobozi bwayo bwo kuramba no gutunganya ibintu neza.
Ibikoresho by'ubuhanga: Mu bikoresho by'ubuvuzi n'ibikoresho by'amaso, ubwiza n'ubudahangarwa bya POM bitanga umusaruro mwiza mu bice nka syringe plunger na lens mounts.

Igenzura ry'umusaruro n'ubuziranenge
Uburyo bwo gukora
Polymerization: Ikorwa binyuze muri cationic/anionic polymerization ya formaldehyde, hamwe n'ibikomeza ubushyuhe byongewemo kugira ngo birusheho gukomera.
Guteranya: Gukomezwa na fibre y'ikirahure, fibre ya karuboni, cyangwa amavuta yo kwisiga kugira ngo ahuzwe n'imiterere (urugero, POM yuzuye ikirahure kugira ngo irusheho gukomera cyangwa ubushobozi bwo kwisiga ku buryo bworoshye gukoreshwa mu gihe cyo gucika intege).
Amahame y'Ubuziranenge
Isuzuma rya Mekanike: Ingufu zo gukurura, kurekura igihe cyo kuruhuka, n'uburyo bwo gukurura imitsi bwapimwe hakurikijwe ISO 527 na ASTM D638.
Isuzuma ry'ubushyuhe: Ubushyuhe bwo guhindagurika k'ubushyuhe (HDT) n'igipimo cy'umuvuduko ushonga (MFI) bipimwe hakurikijwe ISO 75 na ASTM D1238.
Kugenzura Isuku: Ingano y'icyuma gikomeye
Kuki twahitamo POM Resin yacu?
Umusaruro mwiza: POM yacu itanga kristali ihoraho (75±5%) n'imbaraga zo gukurura (≥65 MPa), irusha amanota asanzwe mu kurwanya umunaniro (≥1 miliyoni).
Ibisubizo byihariye: Imiterere yihariye ijyanye n'ibyo ukeneye:
Ubudahangarwa bw'ubushyuhe bwinshi: Ingano zahinduwe kugira ngo zikoreshwe buri gihe muri moteri z'imodoka.
Gutinda k'umuriro: Amanota yemewe na UL 94 V-0 ku bikoresho by'ikoranabuhanga.
Kuramba: Ingano zishobora kongera gukoreshwa (igipimo cyo kongera gukoreshwa nyuma y’inganda ≥90%) n’umusaruro muke wa karuboni (ikoreshwa ry’ingufu rigabanukaho 15% ugereranyije n’impuzandengo y’inganda).
Iyubahirizwa ry’amategeko ku isi yose: Yemejwe na ISO 9001, FDA (ibiryo bikorana), na RoHS/REACH ku bikoresho by’ikoranabuhanga, hamwe no gutanga vuba (ibyumweru 2-4 ku isi yose).
Ubwubatsi bw'Ubuhanga mu Gutwara Moteri mu Guhanga udushya mu by'Iplasitiki
Kuva ku bice by'ingenzi by'imodoka kugeza ku bikoresho by'ikoranabuhanga bigezweho, resin ya POM ikomeje gusobanura neza ibyo pulasitiki y'ubuhanga ishobora kugeraho. Uruvange rwayo rwihariye rw'ubuhanga mu by'ikoranabuhanga, ubushobozi bwo guhangana n'ibinyabutabire, no koroshya imikorere bituma iba ingenzi mu nganda. Hitamo POM yacu kugira ngo ubone uburyo bwo kwizerwa, gukora neza, no guhanga udushya—aho buri gice ari igihamya cy'uko imikorere ya pulasitiki ihujwe no kuramba kwayo.
