Cov txiaj ntsig ntawm iav ntim polypropylene yog dab tsi?
iav-polypropylene puv (PP-GF) yog cov khoom siv dav siv ntau yam uas polypropylene, ntau yam thiab nqi-polymer zoo paub txog nws cov tshuaj tiv thaiv zoo, tsis tshua muaj siab, thiab yooj yim ntawm kev ua, yog mechanically enhanced los ntawm suav nrog iav fibers. Cov txiaj ntsig tseem ceeb ntawm kev ntxiv cov iav fibers (GF) rau polypropylene yog kev txhim kho tseem ceeb hauv nws cov khoom siv kho tshuab. Qhov no suav nrog kev ua kom muaj zog tensile, nruj dua (flexural modulus), txhim kho qhov ruaj khov, thiab txhim kho cov cua sov deflection kub piv rau PP unfilled. Cov cuab yeej txhawb nqa no tso cai rau iav- puv polypropylene siv rau hauv cov ntawv thov ntau dua, feem ntau yog ib qho kev sib tw rau cov khoom siv xws li hlau hauv ntau qhov kev lag luam, suav nrog cov khoom siv tsheb xws li cov duab dashboard ncej.
Txawm li cas los xij, qhov tseeb ntawm cov txiaj ntsig no, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev cuam tshuam thiab kev ncaj ncees ntawm cov qauv hauv cov khoom hnyav, yog qhov cuam tshuam loj heev los ntawm * ntev * ntawm cov iav fibers siv. Qhov no yog qhov twgLFT-G®PP LGF (ntev iav Fiber Polypropylene)distinguishes nws tus kheej. Thaum cov iav ib txwm siv- puv polypropylene feem ntau siv cov iav luv luv (SGF), LFT-G®PP LGF suav nrog cov fibers ntev dua. Cov fibers ntev no yog tsim los tsim ib qho kev sab hauv, peb - qhov ntev ntawm lub cev sib txuas hauv cov polypropylene matrix thaum ua. Qhov no muaj zog, interlocked fiber ntau qauv yog tus yuam sij rau qhib ib tug superior theem ntawm kev ua tau zoo, muab kev cuam tshuam loj zog nqus, txhim kho creep resistance, thiab txhim khu lub neej qaug zog. Rau cov ntawv thov xws li automotive instrument panels lossis lwm yam khoom loj, LFT-G®PP LGF muab kev sib xyaw ua ke tshwj xeeb ntawm lub teeb yuag, lub zog siab, thiab tsim kev ywj pheej tsim nyog rau txoj kev sib txuas, kev sib koom ua ke, xa cov txiaj ntsig zoo tshaj li cov qauv luv fiber ntau PP-GF.
Dab tsi yog cov txiaj ntsig ntawm iav ntev ntim polypropylene?
- Superior Impact Strength & Toughness
- Ua kom muaj zog thiab nruj
- Txhim kho Dimensional Stability & Creep Resistance
- Kev ywj pheej tsim ntau dua rau qhov nyuaj
- Ua kom qaug zog lub neej
- Optimized Lightweighting Potential
