Kupinda muNyika yeEngineering Plastic Materials: Properties uye Application

Munzvimbo yesainzi yezvinhu, mapurasitiki einjiniya, anozivikanwawo semapurasitiki ekushanda, anomira pachena sekirasi yemapolymeri epamusoro anokwanisa kushingirira kushushikana kwemagetsi pamusoro petembiricha yakakura uye kumirisana nehutsinye hwemakemikari nenzvimbo dzemuviri. Zvishandiso izvi zvinozivikanwa nekuenzana kwazvo kwesimba, kusimba, kuramba kupisa, kuoma, uye kuramba kuchembera. Mumashoko akareruka, mapurasitiki einjiniya ndiyo "crème de la crème" yeindasitiri yepurasitiki, inoshanda sembiru dzinokosha dzechikamu.

Kunzwisisa Injiniya Plastiki

Injiniya mapurasitiki haana kusikwa akaenzana. Vanoiswa mumapoka makuru maviri:

1. Thermoplastics:Mapurasitiki aya anopfava uye anonyunguduka kana apiswa, achiabvumira kuti aumbe kuita zvakasiyana-siyana. Mienzaniso yakajairika inosanganisira:

• Polycarbonate (PC):Inozivikanwa nekujeka kwayo kunoshamisa, kupikisa kwemaitiro, uye kugadzikana kwedimensional.
• Polyamide (PA):Inoratidzwa nekusimba kwepamusoro, kuoma, uye kupfeka kuramba.
• Polyethylene Terephthalate (PET):Inoshandiswa zvakanyanya kune yayo yakanakisa makemikari kuramba, dimensional kugadzikana, uye chikafu-giredhi zvivakwa.
• Polyoxymethylene (POM):Inozivikanwa nekudzikama kwayo kwakasarudzika, kukwesha kwakaderera, uye kuomarara kwakanyanya.

2. Thermosets:Kusiyana ne thermoplastics, thermosets inoomesa zvachose pakurapa, zvichiita kuti isagoneke. Mienzaniso inosanganisira:

• Epoxy resins:Inokosheswa nekuda kwesimba ravo repamusoro, makemikari kuramba, uye magetsi ekudzivirira zvinhu.
• Phenolic resins:Kuzivikanwa nekunaka kwavo moto kuramba, makemikari kuramba, uye dimensional kugadzikana.
• Silicone resins:Inozivikanwa nekunyanya kupisa tembiricha kuramba, kuchinjika, uye biocompatibility.

Zvishandiso zveEngineering Plastic Materials

Mapurasitiki einjiniya akapinda mumaindasitiri akasiyana siyana nekuda kweakasarudzika zvivakwa uye kuita zvakasiyana. Heano mamwe maapplication anozivikanwa:

1. Motokari:Mapurasitiki einjiniya anoshandiswa zvakanyanya muzvikamu zvemotokari nekuda kwehuremu hwawo, simba, uye kugona kumira munzvimbo dzakaoma.

2. Zvemagetsi neMagetsi:Yavo yakanakisa magetsi ekudzivirira zvivakwa anoita mapurasitiki einjiniya akanakira zvinhu zvemagetsi, zvinobatanidza, uye mabhodhi edunhu.

3. Zvishandiso:Mapurasitiki einjiniya anowana kushandiswa kwakapararira mumidziyo nekuda kwekugara kwayo, kuramba kupisa, uye kuramba kwemakemikari.

4. Zvishandiso zvekurapa:Biocompatibility yavo uye sterilization kuramba inoita mapurasitiki einjiniya akakodzera kuisirwa pakurapa, zviridzwa zvekuvhiya, uye midziyo yekuendesa zvinodhaka.

5. Muchadenga:Mapurasitiki euinjiniya anoshandiswa muaerospace application nekuda kwereshiyo yesimba-kusvika-uremu, kuramba kutonhora kwakanyanya, uye kuramba kuneta.

Kusarudza iyo Yakakodzera Injiniya Plastic Material

Kusarudza yakakodzera einjiniya epurasitiki zvinhu kune chaiyo application kunoda kunyatsotarisisa zvinhu zvakati wandei, zvinosanganisira:

• Mechanical properties:Simba, kuoma, ductility, kukanganisa kuramba, uye kuneta kuramba.
• Thermal properties:Heat resistance, melting point, tembiricha yegirazi yekuchinja, uye thermal conductivity.
• Chemical properties:Chemical resistance, solvent resistance, uye biocompatibility.
• Maitiro ekugadzirisa:Moldability, machinability, uye weldability.
• Mutengo uye kuwanikwa:Mutengo wezvinhu, mutengo wekugadzira, uye kuwanikwa.

Mhedziso

Zvigadzirwa zvemapurasitiki einjiniya zvakashandura maindasitiri akasiyana nekuda kwezvimiro zvavo zvinoshamisa uye mashandisirwo akawandisa. Kugona kwavo kumirisana nemhoteredzo dzinoda, pamwe nekuita kwavo kwakasiyana-siyana uye kudhura, kwakavaita zvinhu zvakakosha mumhando dzakasiyana dzezvigadzirwa. Sezvo tekinoroji ichifambira mberi uye sainzi yezvinhu zvinoshanduka, mapurasitiki einjiniya akagadzirira kuenderera mberi nekuita basa rakakosha mukugadzira ramangwana rekuvandudza.

Nekubatanidza iwo akakosha mazwi mukati mese blog post uye kutora chimiro chakarongeka, izvi zvirimo zvakagadziridzwa kuti yekutsvaga injini ionekwe. Kusanganisirwa kwemifananidzo yakakodzera uye misoro midiki ine ruzivo inowedzera kuwedzera kuverenga uye kuita.
