Polyoxymethylene (POM) Resin: Piny ma pire tek ma kelo aloka loka i tic mi yubu piny
Nyamu tic: Piny maber miyo bero matung tung
Teko mi cuma ma ukoc
Teko mi ngwec: 60-70 MPa, ma juporo ku piny moko ma juyubu ku cuma, ma ketho ebedo tek ni rwinyo piny i kare ma tek.
Bending Modulus: 2.5–3.0 GPa, ma mio kony ma tek ni piny ma tingo pek.
Teko pa rwinyo: Coefficient ma nok mi rwinyo (0.1-0.3 i thenge ma rwinyo) miyo ebedo ber pi loko/loko piny calu gears, pulleys, man sprockets, dwoko piny rwinyo man medo kwo pa jam tic.
Fatigue Resistance: Ucungu ikum peko ma romo miliyon mapol manangu epodho ngo, ber pi jam tic ma jucaku-juko nja nyo ke jube ketho kare ku kare.
Bedo maber pa kemikol
POM kwetu piny ma nyayu lyethu, moo, acid ma nyap, man alkalis, ma gwoko bedoleng i kabedu ma iye tek. Ku lapor, i kabedo mi mutukari, jamb tic pa POM (calu, fuel pump gears) ciro moo pa mutukari, pii ma ngic, man lyethu ma malo manangu epe ku lyethu nyo lyethu. Ento, ecopu nyothre i thenge ma tek pa acid, alkalis, nyo lyethu ma tek.
Tic maber mi lyethu
Temperature mi loko lyethu: 136-162°C (i the 0.45 MPa load), ku lyethu mi tic ma rwinyo 85-105°C, maber pi tic ma mitu lyethu ma rwinyo.
Thermal Conductivity ma nok: 0.22–0.35 W/(m·K), ma mio kero mi gwoko lyethu i jam tic ma tiyo ku mac.
Jam gwoko mac maber
Volume Resistivity: 1013–1014 Ω·cm, ku dielectric constant pa 3.7–3.9 (i 1 MHz), ma gwoko tic maber mi gwoko piny i kind lyethu/ngic man frequency bands.
Tic: Ber pi jam tic pa mac calu switches, terminal blocks, man ot pa mac, ma jwigo peko mi pii ma wok nyo short circuits.
Tic matung tung
POM's maber pa melt fluidity konyowa ni yubu piny maber nikadhu kud i injection molding, extrusion, blow molding, man mukende mapol, ku kare manok man tic maber. Eni miyo etiye ber pi yubu piny madwong ma tung tung, ma romo ku yeny pa ju ma timo tic.
Kabedo mi tic: Nwangu piny madwong ma kelo dongo dongo mi tic
Tic mi yiku mutukari: Kony maber pi piny ma pire tek
Jam tic: Jam tic mi pii ma juyubu ku POM miyo tic maber i thenge mi pii ma tek, foc ni friction ma nok, kero mi rwinyo, man bedo maber pa kemikol, ma weko pii wok maber.
Kit mi iye: Jam mako dhugola, gears mi gwoko dirisa, man jam ketho kombe tiyo ku tego pa POM pi tic maber man bedo ma rii, man tic pare miyo yore mi yubu piny matung tung.
Yore mi cwalo: Timing pulleys man sprockets ma juyike ku POM tero kero maber ku rwenyo kero manok.
Jam tic mi mac man jam tic mi mac: kony aryo pi tic maber man bedo ber
Kabedo pa jam tic: POM miyo gwok ma tek ni jam tic ma iye man eketho kero pa mac (e.g., fan blades man frames in computer cooling systems, ma gwoko bedo maber i ngwec ma tek manangu eketho ngo piny moko marac).
Jam mako: POM parts miyo rwom ma malu man gen, ma pire tek pi gwoko kero pa mac i connectors.
Jam tic mi tic man jam tic
Jam tic ku cuma: Gears, bushings, man bearings i jam tic mi yubu piny nwango bero kud i POM's wear resistance man dwand ma nok, ma dwoko piny yeny mi gwoko man medo tic maber.
Valves ku Pumps: POM jutiyu kudu i pump pa kemikol man valves pi bedo tek pa nyai, maber pi tero pii ma nyai ungo i tic mi yath man cam.
Piny ma jutiyo kudu man jam tic maber
Piny ma dhanu tiyo kudu: Zippers, jam tic mi sawa, man jam tic mi ot tedo (calu, jam tic mi blender) tiyo ku POM pi bedo moth man kero pare mi yubu piny.
Jam tic maber: I jam tic mi yath man jam tic mi wang, POM's ma ber man ma rwinyo timo tic maber i jam tic macalo syringe plungers man lens mounts.

Yubu man gwoko ber pa piny
Yore mi yubu piny
Polymerization: Juyike ku cationic/anionic polymerization pa formaldehyde, ku stabilizers maju medo pi medo thermal stability.
Medu: Juyike ku glass fiber, carbon fiber, nyo lubricants mi yubu piny (e.g., glass-filled POM pi medo kero nyo self-lubricating grades pi low-friction applications).
Ber pa piny
Temo mi cuma: Teko mi ngwec, bor pa kare mi turo, man rwom mi ngwec ma jutemo nimakere ku ISO 527 man ASTM D638.
Temo lyethu: lyethu ma lyethu (HDT) man rwom pa mol pa lyethu (MFI) ma jupimu nimakere ku ISO 75 man ASTM D1238.
Gwoko leng: Piny ma pek utiye
Pirango ma wayero POM Resin mwa?
Tic maber: POM mwa mio crystallinity (75±5%) man tensile strength (≥65 MPa), maber uloyu rwom ma malu i fatigue resistance (≥1 million cycles).

Lubu cik mi ng'om zoo: Juyio ni ISO 9001, FDA (food food), man RoHS/REACH pi jam tic mi mac, ku cwalo piny pio pio (2-4 yenga i ng'om zoo).
Engine Driving Engineering Plastics Innovation
Nicaku ikum piny ma pire tek mi mutukari nitundu ikum piny ma tiyo ku mac, POM resin umediri ku loko ango ma plastics mi engineering copo timo. Kit pare ma ukoc ku kero pa cuma, tek pa kemikol, man bedo yot pa timo piny miyo etiye piny ma pire tek i dilo zo. Yer POM mwa mi yabo gen, tic maber, man ryeko manyen- kama piny moko ci utiye lanyuth pa tic pa plastik man kero pa cuma.
