Kuzarura Musiyano Pakati peGeneral-Purpose uye Engineering Plastics: A Comprehensive Guide

Munzvimbo yemapurasitiki, musiyano wakajeka uripo pakati pechinangwa-chinangwa uye mapurasitiki einjiniya. Nepo ese ari maviri achishandira zvinangwa zvakakosha, anosiyana zvakanyanya mumidziyo yavo, mashandisirwo, uye kuita kwese. Kunzwisisa misiyano iyi kwakakosha pakusarudza akakodzera epurasitiki zvinhu kune chaiwo zvinodiwa.

General-Purpose Plastics: Iwo Akasiyana-siyana Workhorses

General-chinangwa mapurasitiki, anozivikanwawo semapurasitiki emidziyo, anoratidzirwa nekugadzirwa kwawo kwakakwira, huwandu hwakawanda hwekushandisa, nyore kugadzirisa, uye mutengo-kushanda. Ivo vanoumba musana weindasitiri yepurasitiki, vachipa zvinhu zvemazuva ese zvevatengi uye zvisingadi kunyorera.

Common Characteristics:

• High Production Volume:General-chinangwa mapurasitiki anodarika 90% yehuwandu hwekugadzirwa kwepurasitiki.
• Broad Application Spectrum:Zvinowanikwa pese-pese mukurongedza, zvinhu zvinoraswa, matoyi, uye zvinhu zvemumba.
• Kureruka kweKugadzirisa:Kuumbwa kwavo kwakanakisa uye machinability kunobatsira kugadzira-inodhura.
• Affordability:General-chinangwa mapurasitiki haana kudhura, zvichiita kuti ataridzike mukugadzirwa kwehuwandu.

Mienzaniso:

• Polyethylene (PE):Inoshandiswa zvakanyanya kumabhegi, mafirimu, mabhodhoro, uye pombi.
• Polypropylene (PP):Inowanikwa mumidziyo, machira, uye zvinhu zvemotokari.
• Polyvinyl Chloride (PVC):Vanoshanda mupombi, mafittings, uye zvekuvakisa.
• Polystyrene (PS):Inoshandiswa kurongedza, matoyi, uye midziyo inoraswa.
• Acrylonitrile Butadiene Styrene (ABS):Zvakajairika mumidziyo, zvemagetsi, uye mikwende.

Injiniya Plastics: Izvo Zvinorema zveIndasitiri

Injiniya mapurasitiki, anozivikanwawo semapurasitiki ekuita, akagadzirirwa kusangana nezvinodiwa zvemaindasitiri ekushandisa. Ivo vanokunda musimba, kupikisa kwemaitiro, kushivirira kupisa, kuoma, uye kuramba kuchembera, zvichiita kuti ive yakanaka kune zvimiro zvemukati uye nharaunda dzinonetsa.

Hunhu Hunozivikanwa:

• Superior Mechanical Properties:Mapurasitiki einjiniya anomira kushushikana kwemagetsi uye nharaunda dzakaomarara.
• Exceptional Thermal Stability:Vanochengetedza zvinhu zvavo pamusoro pehupamhi hwekushisa.
• Chemical Resistance:Injiniya mapurasitiki anogona kutsungirira kuratidzwa kune akasiyana makemikari uye zvinonyungudutsa.
• Dimensional Kugadzikana:Vanochengetedza chimiro chavo uye hukuru pasi pemamiriro akasiyana.

Applications:

• Motokari:Mapurasitiki einjiniya anoshandiswa zvakanyanya muzvikamu zvemotokari nekuda kwekureruka kwavo uye kugara kwenguva refu.
• Zvemagetsi neMagetsi:Mamiriro avo emagetsi ekudzivirira anoita kuti ave akakodzera kune zvikamu zvemagetsi uye zvibatanidza.
• Zvishandiso:Mapurasitiki einjiniya anowana kushandiswa kwakapararira mumidziyo nekuda kwekudzivirira kwayo kupisa uye kusimba kwemakemikari.
• Midziyo yekurapa:Yavo biocompatibility uye sterilization kuramba inoita kuti ive yakanakira ma implants ekurapa uye maturusi ekuvhiya.
• Aerospace:Mapurasitiki einjiniya anoshandiswa muaerospace application nekuda kwehuwandu hwesimba-kusvika-huremu uye kuramba kuneta.

Mienzaniso:

• Polycarbonate (PC):Inozivikanwa nekujeka kwayo, kukanganisa 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.

Kusarudza Plastiki Yakakodzera YeBasa

Kusarudza iyo yakakodzera plastiki zvinhu zvinoenderana neiyo chaiyo application zvinodiwa. General-chinangwa mapurasitiki akanakira kudhura-sensitive, kusingade maapplication, nepo mainjiniya einjiniya akakodzera zvirinani kune yakaoma nharaunda uye inoda maitiro ekuita.

Zvinhu Zvokufunga nezvazvo:

• Mechanical Zvinodiwa:Simba, kuomarara, kukanganisa kupikisa, uye kuramba kuneta.
• Thermal Performance:Heat resistance, melting point, tembiricha yegirazi yekuchinja, uye thermal conductivity.
• Chemical Resistance:Kusangana nemakemikari, zvinonyungudutsa, uye nharaunda dzakaoma.
• Maitiro ekugadzirisa:Moldability, machinability, uye weldability.
• Mutengo uye Kuwanikwa:Mutengo wezvinhu, mutengo wekugadzira, uye kuwanikwa.

Mhedziso

General-chinangwa uye mainjiniya mapurasitiki ega ega anoita basa rakakosha munyika dzakasiyana dzemapurasitiki ekushandisa. Kunzwisisa kwavo kwakasarudzika zvivakwa uye kukodzera kune zvakati zvinodiwa kwakakosha pakuita sarudzo yeruzivo rwezvinhu. Sezvo tekinoroji ichifambira mberi uye sainzi yezvinhu zvinoshanduka, ese marudzi epurasitiki acharamba achifambisa hunyanzvi uye kugadzira ramangwana remaindasitiri akasiyana.

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.
