POM ukwaziswa
Kwadalwa ngo 08.07
POM (Polyoxymethylene, abbreviated POM) ke plastiki ya injin mai inganci, wanda aka fi sani da resin polyoxymethylene, acetal, ko supersteel. Yana da babban ƙarfi, ƙarfi, da juriya ga gajiya. Wani polymer ne mai layi tare da babu gefen igiyoyi, babban ƙima, da babban crystallinity. Bisa ga tsarin sinadarai na igiyar kwayar halittarsa, POM na iya rabuwa zuwa homopolyoxymethylene da copolymers. Homopolyoxymethylene yana da babban ƙima, crystallinity, da maki narkewa, amma yana da rauni a cikin juriya ga zafi da kuma ƙaramin zangon zafin aiki. Copolymers, a gefe guda, suna da mafi kyawun juriya ga zafi da kuma faɗin zangon zafin aiki.

Mechanical Properties: POM exhibits high strength, high rigidity, and excellent creep and fatigue resistance. Its tensile strength can reach 70 MPa and its impact strength is 13.8 kJ/m², making it suitable for parts requiring high strength and wear resistance.
Thermal Properties: The melting point of homopolyoxymethylene is 175°C, while the melting point of copolymerized oxymethylene is slightly lower at 165°C. Although POM decomposes easily at high temperatures, the addition of heat stabilizers can extend its processing temperature range.
Imiphumela Yamakhemikhali: I-POM inokuqina okuhle kumasolvents amaningi ombala nezinsiza, kodwa ayizinzile kakhulu kumasidi anamandla nezisekelo. Ngenkathi izinzile kumakhemikhali ombala ekamelweni lokushisa, ukumelana kwayo namakhemikhali kwehla ezingeni eliphezulu lokushisa.
Electrical Properties: POM has excellent electrical insulation properties and high dielectric strength, making it suitable for various parts in the electrical and electronic fields. Components
Other Properties: POM has low water absorption, excellent dimensional stability, and strong weather and UV resistance, making it suitable for outdoor use.
Izicelo
Automotive: POM is used in carburetor components, fuel lines, pumps, power valves, bearings, gears, and other applications. Its high mechanical strength and wear resistance make it an ideal metal replacement.
Electronic and Electronic: POM is used in connectors, plug-in components, switches, buttons, relays, and other components due to its high dielectric strength and excellent electrical insulation properties.
Other Applications: POM is also used in anti-friction and wear-resistant parts, transmission components, chemical and instrumentation components, and more.
