Cov khoom siv LFT yog dab tsi?
Ntev fiber ntau reinforced thermoplastic cov ntaub ntawv xa mus rau cov khoom siv ntxiv nrog cov fiber ntau ntev li ntawm 5 txog 25 hli. Lawv yog tsim los ntawm tag nrho impregnating nruam fiber bundles nrog molten thermoplastic resins (xws li PP, PA, PBT, thiab lwm yam) thiab ces pelletizing lawv. Piv nrog luv- fiber ntau cov ntaub ntawv (fiber length<1 mm), it retains a more complete fiber structure, enabling the products to achieve performance close to that of continuous fiber composites.
Hauv kev tshawb fawb ntawm cov ntaub ntawv tshawb fawb, ntev - cov ntaub ntawv fiber ntau tau maj mam dhau los ua cov nyiam tshiab hauv kev tsim khoom lag luam vim lawv qhov tshwj xeeb zoo ntawm cov qauv thiab kev ua tau zoo. Cov khoom siv sib xyaw no txhawb nqa nrog txuas ntxiv lossis ntev - txiav fibers, los ntawm cov txheej txheem tsim tshwj xeeb, tau ua tiav qhov kev ua tau zoo ntawm cov khoom siv thaum tswj kev ncaj ncees ntawm cov fibers.
Peb LFT PP LGF Pellets ua li cas?
Cov txheej txheem kev npaj yog qhov txiav txim siab rau kev ua haujlwm ntev - cov ntaub ntawv fiber ntau. Tsis zoo li kev sib xyaw yooj yim ntawm cov khoom siv sib xyaw ua ke, kev tsim cov khoom siv fiber ntau ntev - cov khoom siv fiber ntau ua rau kev saib xyuas ntawm fiber ntau ntev thiab kev tswj kev taw qhia. Cov txheej txheem impregnation ncaj qha tswj qhov kub, siab, thiab fiber ntau nro ntawm cov resin yaj, tso cai rau cov resin kom tag nrho impregnate fiber bundles thaum txo cov fiber ntau puas.
Cov txheej txheem no zoo li yooj yim tiag tiag yuav tsum tau daws ntau yam teeb meem engineering xws li resin viscosity, fiber testability, thiab uniformity ntawm impregnation. Hmoov zoo, nrog kev paub nplua nuj, peb tuaj yeem daws cov teeb meem no tau zoo thaum tsim khoom ntev - fiber ntau.
Vim li cas thiaj xaiv LFT PP LGF Composites?
LGF PP khoom yog ntxiv nrog cov fibers txuas ntxiv, uas tuaj yeem cuam tshuam cov quab yuam tau zoo dua. Nyob rau tib lub sijhawm, qhov cuam tshuam tsis zoo ntawm LGF PP cov ntaub ntawv tseem muaj zog dua ob zaug ntawm cov khoom siv SGF PP.
LGF PP cov ntaub ntawv muaj qhov ua tau zoo thiab muaj txiaj ntsig zoo ntawm kev sib tw. Yog tias siv rau hauv cov khoom siv tsheb, nws tuaj yeem tsis tsuas yog nce lub neej ntawm cov khoom, tab sis kuj txo qhov hnyav tag nrho ntawm lub tsheb.
