gf30 khoom yog dab tsi?
Lo lus "GF30 khoom" feem ntau yog hais txog cov khoom siv polymer uas tau ntxiv dag zog nrog 30% iav fibers (GF) los ntawm qhov hnyav. Lub "GF" qhia txog kev suav nrog cov iav fibers, thiab "30" qhia lawv cov ntsiab lus feem pua. Hom kev txhawb nqa no feem ntau siv rau ntau lub hauv paus polymers - xws li polypropylene (PP), polyamide (PA, nylon), lossis polybutylene terephthalate (PBT) - txhawm rau txhim kho lawv cov khoom siv hluav taws xob thiab thermal. Ntxiv cov iav fibers feem ntau ua rau muaj zog ntxiv, nruj dua (modulus), txhim kho qhov ruaj khov ntawm qhov kub siab, thiab siab dua kub deflection kub piv rau lub hauv paus tsis muaj zog polymer. Qhov no ua rau GF30 cov ntaub ntawv tsim nyog rau ntau yam kev siv engineering uas yuav tsum tau ua kom zoo dua qub.
Txawm li cas los xij, qhov sib txawv tseem ceeb hauv GF30 cov ntaub ntawv nyob hauv * ntev * ntawm cov iav fibers siv, uas cuam tshuam rau qhov kev ua tau zoo kawg. Qhov no yog qhov twgLFT-G®PP LGF 30, tshwj xeeb ntev iav Fiber Polypropylene, tiag tiag sawv tawm. Txawm hais tias muaj ntau cov khoom siv "GF30" siv cov iav luv luv (SGF), LFT-G®PP LGF30 suav nrog cov fibers ntev dua. Cov fibers ntev no, lub cim tseem ceeb ntawm Long Fiber Technology (LFT), tau ua tib zoo tsim los tsim kom muaj lub zog, sib cuam tshuam peb -cov pob txha fiber ntau nyob rau hauv polypropylene matrix thaum lub sijhawm molding. Cov qauv kev sib koom ua ke no yog lub hauv paus ntawm cov khoom zoo tshaj plaws uas tau nthuav tawm los ntawm LFT-G®PP LGF30, xws li kev txhim kho kev cuam tshuam zoo heev, txhim kho kev nkag siab thiab qaug zog, thiab kev ua haujlwm zoo dua qub, tshwj xeeb tshaj yog nyob rau hauv txoj kev, thauj khoom -cov kabmob feem ntau pom nyob rau hauv tsheb lossis kev lag luam kev siv (raws li piv txwv los ntawm tus neeg sawv cev LFT pellets lossis cov qauv tsim tau pom). Yog li, thaum "GF30" yog tus piav qhia dav dav, "LGF30" qhia txog qib siab dua ntawm kev ua haujlwm.
Cov txiaj ntsig ntawm iav fiber ntau PP yog dab tsi?
- Qhov zoo tshaj plaws Impact Resistance thiab Toughness
- Txhim kho Tensile thiab Flexural Strength zoo heev
- Ua kom nruj thiab Load-Bearing Capability
- Txhim kho Creep Resistance nyob rau hauv Sustained Load
- Zoo dua Dimensional Stability & Txo Warpage nyob rau hauv loj qhov chaw
- Nthuav Nthuav Lub Neej Thiab Ua Si nyob rau hauv Cyclic Loading
- Txhim khu Weld Line Strength thiab Integrity
- Optimized Lightweighting nrog siab zog tshwj xeeb

LFT-G®Ntev fiber ntau PP rau Automotive Part Solutions
LFT-G®PP LGF30 (ntev iav fiber ntau polypropylene 30%)stands raws li cov ntaub ntawv tseem ceeb rau lub tshiab automotive ib feem kev daws teeb meem, enabling engineers kom tau raws li kev lag luam xav tau rau lub teeb yuag, txhim khu kev ruaj ntseg, thiab txhim kho kev ua tau zoo. Qhov tshwj xeeb ntev fiber ntau qauv hauv peb PP LGF30 muab qhov tshwj xeeb sib npaug ntawm lub zog, nruj, thiab kev cuam tshuam tsis zoo, ua rau nws zoo tagnrho rau ntau yam ntawm cov qauv thiab ib nrab - cov khoom siv. Automotive manufacturers leverage LFT-G®PP LGF30 los hloov cov ntaub ntawv hnyav dua li cov hlau lossis txhuas hauv cov ntawv thov xws li pem hauv ntej -kawg modules, cov khoom siv vaj huam sib luag, cov rooj sib tham ntawm lub qhov rooj, cov ntaub thaiv npog hauv qab, thiab cov roj teeb vaj tsev rau cov tsheb fais fab.
Qhov zoo dua li kev hloov khoom siv. Kev tsim qauv yooj yim them los ntawm LFT-G®PP LGF30 tso cai rau kev sib koom ua ke ntawm ntau lub zog rau hauv ib qho, qhov nyuaj molded, yog li txo cov khoom suav, ua kom yooj yim rau kev sib dhos, thiab txo cov nqi tag nrho. Tsis tas li ntawd, nws qhov kev ruaj ntseg zoo heev thiab ua haujlwm rau cov kua hauv tsheb thiab qhov kub thiab txias hloov ua kom ntev - lub sij hawm durability thiab kev ntseeg siab ntawm cov khoom tsim. Los ntawm kev koom tes nrog LFT-G®rau PP LGF30 cov kev daws teeb meem, cov neeg siv tsheb tau txais kev nkag mus rau cov khoom siv thev naus laus zis uas ua rau muaj kev tsim kho tshiab thiab pab txhawb rau kev txhim kho cov tsheb sib zog, kev nyab xeeb, thiab siv tau zoo dua.
