- Polycarbonate (PC):Qhov ntau yam polymer no muaj qhov sib npaug zoo ntawm lub zog, pom meej, thiab cuam tshuam tsis kam.Nws yog dav siv nyob rau hauv cov khoom siv kev nyab xeeb, mos mos-resistant qhov rais, thiab cov khoom siv.
- Acrylonitrile Butadiene Styrene (ABS):Paub txog nws lub zog zoo, tawv, thiab kev ua haujlwm yooj yim, ABS yog qhov kev xaiv nrov rau ntau yam kev siv xws li cov khoom siv tsheb, cov kav dej, thiab cov khoom siv hluav taws xob.
- Ultra-siab Molecular Nyhav Polyethylene (UHMWPE):Kev khav theeb tshwj xeeb hnav tsis kam thiab kev sib txhuam qis, UHMWPE pom cov ntawv thov hauv cov pob qij txha, cov kabmob, thiab cov ntaub qhwv.
Cov txiaj ntsig ntawm Kev Siv Lub Zog Muaj Zog Polymers
Lub zog muaj zog polymers muaj ntau yam zoo dua li cov ntaub ntawv ib txwm siv, ua rau lawv zoo tagnrho rau ntau yam kev siv:
- Lub teeb:Piv nrog rau cov hlau, lub zog muaj zog polymers muaj qhov hnyav hnyav, uas yog qhov tseem ceeb hauv kev siv xws li aerospace thiab kev thauj mus los.
- Durability:Cov polymers no nthuav tawm tshwj xeeb rau kev hnav, tsim kua muag, cuam tshuam, thiab tshuaj lom neeg, ua kom muaj kev ua haujlwm ntev.
- Versatility:Lub zog muaj zog polymers tuaj nyob rau hauv ntau yam ntaub ntawv, nrog rau fibers, films, nplooj ntawv, thiab hlab, catering rau ntau yam ntawm cov qauv tsim.
- Corrosion Resistance:Tsis zoo li cov hlau, muaj zog polymers feem ntau tiv taus corrosion, txo cov kev xav tau ntawm kev saib xyuas.
- Tsim Flexibility:Ntau lub zog muaj zog polymers tuaj yeem yooj yim molded, zoo li tus, thiab fabricated, ua rau cov qauv tsim.
Kev siv ntawm High Strength Polymers
Qhov tshwj xeeb lub zog thiab ntau yam ntawm cov polymers ua rau lawv zoo tagnrho rau ntau yam kev siv thoob plaws kev lag luam:
- Aerospace:High zog polymers yog siv nyob rau hauv aircraft Cheebtsam, fuselage panels, thiab structural yam vim lawv lub teeb yuag thiab siab zog zog.
- Automotive:Cov khoom xws li bumpers, fenders, thiab cov khoom siv sab hauv feem ntau siv cov polymers siab zog rau lawv qhov hnyav-txuag cov txiaj ntsig thiab tsim kev yooj yim.
- Kev tsim kho:Cov kav dej, cov vov tsev, thiab cov khoom siv dag zog tuaj yeem ua kom muaj zog thiab ua haujlwm ntev ntawm lub zog siab polymers.
- Cov khoom siv ncaws pob:Los ntawm cov cuab yeej ua kis las ua tau zoo xws li caij skis thiab tsheb kauj vab thav duab rau cov iav tiv thaiv, cov khoom siv polymers muaj zog txhawb kev ua haujlwm thiab kev nyab xeeb.
