Indasitiri yepurasitiki inomira sembiru yehupfumi hwemazuva ano, ichishandura zvikamu zvakasiyana-siyana kubva pakugadzirwa kweBakelite, yekutanga purasitiki yekugadzira, muna 1907. Kufambira mberi kwemazana emakore kwakaona kubuda kwemhando dzakasiyana-siyana dzeinjiniya mapurasitiki, rimwe nerimwe richipa zvivakwa zvakasiyana izvo vakashandura kugadzirwa kwechigadzirwa uye kugadzira.
Kupinda muNyika yeInjiniya Plastics
Mapurasitiki einjiniya, anozivikanwawo se thermoplastic polymers, ikirasi yemasaramusi ekugadzira ane mukurumbira nehunyanzvi hwekugona kuita zvichienzaniswa nemapurasitiki akajairwa. Zvishandiso izvi zvinoratidza musanganiswa unoshamisa wesimba, kusimba, uye kuita kwakasiyana-siyana, zvichiita kuti zvive zvakanakira kudikanwa kwekushandisa mumhando dzakasiyana dzemaindasitiri.
Kufumura Pfuma yeZvivakwa
Kukwezva kweinjiniya mapurasitiki ari muhuwandu hwawo hwakakura hwezvivakwa zvinopa kune akasiyana mainjiniya zvinodiwa. Ngationgororei mamwe emhando dzakakosha dzinosiyanisa zvinhu izvi:
- Mechanical Simba:Mapurasitiki einjiniya ane simba rinoshamisa rekusimba, kupikisa kwemaitiro, uye kugadzikana kwechimiro, zvichivagonesa kutsungirira nharaunda dzakaomarara uye kushushikana kwemagetsi.
- Thermal Stability:Zvinhu izvi zvinoratidzira kupikisa kwakasarudzika kune tembiricha yakakwira, zvichiita kuti zvikodzere maapplication anosanganisira kuratidzwa kwekupisa kana kuchinjika kwakanyanya.
- Chemical Resistance:Mapurasitiki einjiniya haapindire kumakemikari, maasidhi, uye zvinonyungudutsa, kuve nechokwadi chekutendeseka kwavo munzvimbo dzakaoma dzemakemikari.
- Electrical Properties:Mamwe mapurasitiki einjiniya anopa zvakanakisa magetsi ekudzivirira zvivakwa, nepo mamwe anoratidza conductivity, achiaita akakodzera zvinhu zvemagetsi uye maapplication.
- Biocompatibility:Mamwe mapurasitiki einjiniya anoratidza biocompatibility, achiaita akanakira michina yekurapa uye maimplants anosangana nenyama mhenyu.
- Flame Retadancy:Mamwe mapurasitiki einjiniya ane inherent flame retardant properties, kuderedza njodzi dzemoto uye kuwedzera kuchengeteka mumashandisirwo anokosha.
Zvishandiso zveEngineering Plastics: Nyika Yezvinogoneka
Iko kuita kwakasiyana-siyana kweinjiniya mapurasitiki akavhura magonhi kune akawanda akawanda ekushandisa, kushandura maindasitiri uye kuumba hupenyu hwedu hwezuva nezuva. Ngationgororei mimwe mienzaniso yakakurumbira:
- Indasitiri yemotokari:Mapurasitiki einjiniya anoshandiswa zvakanyanya muzvikamu zvemotokari nekuda kwehuremu hwawo, hunogara, uye husingapise kupisa. Iwo anoshandiswa muzvikamu zveinjini, mukati memukati, uye kunze kwemuviri mapaneru.
- Indasitiri yemagetsi:Munzvimbo yemagetsi, mapurasitiki einjiniya anoita basa rakakosha mumabhodhi edunhu, zvinobatanidza, uye dzimba, achipa insulation, simba, uye kugadzikana kwedimensional.
- Indasitiri yezvokurapa:Iyo biocompatible chimiro chemamwe mapurasitiki einjiniya anoita kuti ave akakosha pamidziyo yekurapa, senge maimplants, zviridzwa zvekuvhiya, uye masisitimu ekuendesa zvinodhaka.
- Aerospace Industry:Mapurasitiki euinjiniya anoshandiswa zvakanyanya muzvikamu zvendege nekuda kwehuremu hwawo, huremu hwehuremu hwepamusoro, uye kuramba kutonhora kwakanyanya uye makemikari.
- Consumer Goods:Mapurasitiki einjiniya anowanikwa kwese muzvigadzirwa zvevatengi, kubva kumatoyi nemidziyo kusvika kune zvemitambo uye zvekurongedza zvinhu, nekuda kwekusimba kwavo, kuita zvakasiyana-siyana, uye kukwezva kwerunako.
Engineering Plastic Material Properties: A Resource for Design Kunakisa
Kune mainjiniya nevagadziri vanotsvaga kushandisa simba reinjiniya mapurasitiki, hupfumi hwezviwanikwa huripo kutungamira kuita sarudzo ine ruzivo. Iyo Applied Plastics Engineering Handbook Processing and Materials inoshanda sereferensi yakazara, ichipa ruzivo rwakadzama pamusoro pezvivakwa, maitiro ekugadzirisa, uye mashandisirwo emapurasitiki einjiniya akasiyana.
Mhedziso: Kumbundira Ramangwana reEngineering Plastics
Mapurasitiki einjiniya akachinja dhizaini nekugadzira zvigadzirwa, achipa musanganiswa wakasarudzika wekuita, kuita zvakasiyana-siyana, uye kusimba. Sezvo tsvagiridzo nebudiriro zvichiramba zvichisundidzira miganhu yesainzi yezvinhu, mapurasitiki einjiniya akagadzirira kuita basa rakatonyanya kukosha mukugadzira ramangwana rekuvandudza.
Nekunzwisisa zvakasiyana siyana zvivakwa uye mashandisiro einjiniya mapurasitiki, mainjiniya nevagadziri vanogona kuvhura nyika yemikana, kugadzira zvigadzirwa zvisingashande uye zvinogara kwenguva refu asiwo zvine chekuita nemhoteredzo uye zvinoyevedza.
