LFT-G® PA6 HLGF50|Qhov Kawg Siab -Modulus Hloov Kho rau PA6 GF50
LFT-G® 50% Ntev iav fiber ntau PA6 (High Performance)
Thaum tus qauvPA6 GF50mus txog nws qhov tawg,LFT-G®PA6-HLGF50siv dua. Standard luv luv- fiber ntau 50% iav nylon muaj zog, tab sis nws yog nkig thiab ua rau qaug zog. Peb "High Performance" (HLGF) series yog tsim los rau cov ntawv thov uas txawm tias tus qauv ntev - cov ntaub ntawv fiber ntau tsis txaus.
Cov neeg tseem ceeb qib no siv cov cuab yeej sib txuas ua ke los ua kom muaj kev sib raug zoo ntawm covPolyamide 6matrix thiab loj50% Ntev iav Fibercev pob txha. Qhov tshwm sim yog ib qho kev sib xyaw nrog cov khoom siv kho tshuab10-15% siab duatshaj peb cov qib ntuj, muab cov flexural modulus uas rivals txhuas thaum txiav qhov hnyav los ntawm ib nrab. Nws yog cov khoom siv tseem ceeb rau kev hloov cov hlau hnyav hnyav hauv kev nyab xeeb- kev tsheb ciav hlau tseem ceeb, tsheb, thiab kev lag luam.
- √ Qhov kawg tawv nqaij (+15%):Optimized interface bonding pushes lub flexural modulus tshaj 17,000 MPa, kom ntseeg tau tias xoom deflection nyob rau hauv loj loads.
- √ Lub zog tawg heev:Qhov zoo tshaj plaws rau cov hlab ntsha siab thiab lub cev valve qhov twg tus qauv PA6 GF50 yuav tawg nyob rau hauv siab.
- √ Superior Surface Finish:Advanced impregnation thev naus laus zis ua kom cov fibers tau ntub tag nrho, txo qhov roughness ntawm cov khoom hauv siab - iav cov ntaub ntawv.

Case Study: Hnyav Truck Air Brake Valve
Ib qho tseem ceeb kev nyab xeeb tivthaiv tuav 12-bar cua siab. Failure txhais tau tias tsis muaj zog braking.
Kev xaiv A: Tuag-Aluminium (Failed)
hnyav dhau lawm, yuav tsum tau siv cov khoom siv kim heev rau cov ntsaws ruaj ruaj, thiab raug kev txom nyem los ntawm corrosion thaum lub caij ntuj no.
Kev xaiv B: Standard LGF50 (Marginal)
Tau ntsib thawj zaug tawg siab tab sis ua tsis tiav kev sim qaug zog tom qab 100,000 lub voj voog vim muaj fiber ntau rub - tawm.
Option C: LFT-G®HLGF50 (Winner)

Muaj Titans: Cov ntawv thov heev
Crane Sheaves
Hloov steel pulleys. Cov huab cua compressive zog ntawm HLGF50 tiv taus hnyav cable loads thaum txo qhov hnyav ntawm lub taub hau, txhim kho crane stability.
Rail Insulator Blocks
Siv nyob rau hauv siab - kev tsheb ciav hlau ceev. Cov khoom siv yuav tsum cais tawm hluav taws xob thaum coj tus nqi loj heev ntawm cov tsheb ciav hlau hla tsis muaj crushing lossis creeping.

Cov neeg tseem nug (Google PAA)
1. Puas yog Nylon 6 muaj zog dua li txhuas?
A: Nyob rau hauv cov nqe lus ntawm lub zog kiag li, Aluminium 6061 muaj zog dua. Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm **Lub zog tshwj xeeb** (lub zog- rau- qhov hnyav piv), LFT-G® **PA6 HLG 50** yog superior. Nws tso cai rau cov engineers los tsim cov khoom uas yog 50% sib dua li txhuas tab sis muaj peev xwm tuav tau tib yam khoom thauj khoom, uas yog qhov tseem ceeb rau kev siv tsheb sib tw.
2. Qhov siab tshaj plaws iav fiber ntau hauv Nylon yog dab tsi?
A: Thaum 60% (LGF60) feem ntau yog qhov txwv kev lag luam sab saud, **50% (LGF50)** feem ntau suav hais tias yog "qhov chaw qab zib" rau kev txhaj tshuaj molding. Nws muaj kev dhia loj heev hauv kev nruj dua 30% qib yam tsis muaj kev ua haujlwm hnyav thiab cov teeb meem tiav ntawm qhov chaw cuam tshuam nrog 60% fiber ntau loading.
3. Puas muaj cov ntsiab lus iav siab cuam tshuam pwm shrinkage?
A: Yog, tseem ceeb heev. Lub 50% ntev iav fiber ntau pob txha pob txha nyob rau hauv LFT-G® HLGF50 txo pwm shrinkage mus rau theem qis heev (0.1-0.3%), piv rau tuag- nrum hlau. Qhov no tso cai rau molding ntawm qhov loj, siab - precision qhov chaw nrog tsawg warpage, tsis zoo li unfilled los yog low-fiber nylons.
