LFT-G® PA66 LGF30|Lub Siab -Tshav Kub & Fatigue Upgrade rau PA66 GF30
LFT-G® 30% Ntev iav fiber ntau PA66 (High Strength) PA66 GF 30 yog tus qauv kev lag luam rau siab - qhov kub ntawm cov qauv, nyiam tshaj PA6 rau nws cov ntsiab lus melting ntau dua. Txawm li cas los xij, nyob rau hauv ib puag ncig nrog cyclic thermal stress (cua sov thiab txias) thiab kev co, cov qauv luv fibers feem ntau debond, ua rau qaug zog tawg thiab xau.LFT-G® PA66-LGF30-NG03 yog qhov kev daws teeb meem engineering.
Qhov no Natural Qib (NG03) composite txhawb nqa siab -crystallinePolyamide 66 (Nylon 66) matrix nrog a30% Ntev iav Fiber cev pob txha. Qhov kev sib xyaw ua ke no khaws cov cua sov siab ntawm PA66 (txog 250℃lub sijhawm luv luv) thaum txhim kho kev qaug zog thiab kev nkag siab, ua kom cov khoom tuav lawv cov duab thiab foob nyob rau hauv huab cua kub caij tsheb kauj vab.
√ Superior Thermal Fatigue: Lub entangled fiber network resists tawg propagation tshwm sim los ntawm expansion/contraction cycles, extending ib feem lub neej nyob rau hauv lub cav bays.√ Ntau dua Load ntawm Kub: PA66 LGF30 tuav nruj ntawm qhov kub thiab txias qhov twg PA6 yuav mos, txhawb nqa hnyav dua ntawm 120℃+.√ Warp Resistance: Qhov qis qis anisotropic shrinkage piv rau luv luv -fiber PA66, uas ua rau flatter, ntau qhov tseeb qhov tseeb.
Thermal Fatigue Gap Kev ua tau zoo nyob rau hauv cyclic cua sov (piv txwv li, lub cav pib / nres lub voj voog) + kev vibration load.
