LFT yog dab tsi? Nws sawv rauNtev Fiber Reinforced Thermoplastic. Tab sis lub npe ntawd nyuam qhuav khawb qhov chaw ntawm qhov khoom zoo kawg no tuaj yeem ua tau. Tsis nco qab txhua yam koj xav tias koj paub txog "tus qauv" plastics. Peb tab tom tshawb nrhiav yuav ua li cas ntxiv "pob txha pob txha" rau cov yas tsim kom muaj lub zog hluav taws xob sib xyaw uas hloov txoj kev peb tsim thiab tsim lub ntiaj teb nyob ib puag ncig peb.
Qhov no tsis yog ib zaj lus qhia txog science xwb. Qhov no yog saib mus rau yav tom ntej ntawm kev tsim khoom, qhov twg lub zog, qhov hnyav, thiab tsim kev ywj pheej converge. Wb tau mus rau hauv nws.
Ua ntej, Cia peb tawg: Dab tsi yog "Long Fiber Reinforced Thermoplastic" Tiag tiag?
Txhawm rau kom nkag siab lub zog ntawm LFT, koj yuav tsum nkag siab nws ob lub ntsiab lus tseem ceeb. Xav txog nws zoo li cov pob zeb uas muaj zog ntxiv -koj muaj lub pob zeb nws tus kheej thiab cov hlau rebar uas muab nws lub zog tensile loj heev. LFT ua haujlwm raws li txoj cai zoo sib xws.
Lub "Thermoplastic" Matrix: Lub Re-mouldable Base
Qhov "thermoplastic" yog lub hauv paus yas polymer. Cov piv txwv uas koj yuav paub yog Polypropylene (PP), Polyamide (PA, lossis Nylon), lossis PET. Lub "thermo" prefix txhais tau tias koj tuaj yeem ua kom sov nws mus rau qhov chaw melting, pwm nws mus rau hauv cov duab nyuaj, thiab tom qab ntawd txias nws mus rau lub xeev khov. Qhov zoo tshaj plaws? Koj tuaj yeem rov ua qhov txheej txheem no. Qhov no ua rau cov khoom siv thermoplastics tuaj yeem rov ua dua tshiab thiab muaj ntau yam piv rau lawv cov kwv tij "thermoset", uas tau hloov pauv tsis tau tshuaj thaum kho (xws li epoxy).
Qhov "Long Fiber" Reinforcement: Lub Pob Txha Ntsig
Qhov no yog qhov ua khawv koob tshwm sim. Qhov "ntev fiber ntau" yog hais txog kev txhawb nqa fibers, feem ntau yog iav (LGF) lossis carbon (LCF), uas ntev dua li cov uas pom muaj ntau dua Short Fiber Thermoplastics (SFT).
- Short Fibers (SFT):0.2 hli - 1mm
- Ntev Fibers (LFT):Feem ntau 10mm - 25mm
Vim li cas qhov ntev no tseem ceeb heev? Thaum cov khoom siv LFT raug txhaj tshuaj molded rau hauv ib feem, cov fibers ntev txuas thiab tsim kom muaj zog, peb -cov qauv pob txha nyob hauv cov yas. Qhov "rebar" network sab hauv no yog tus yuam sij rau LFT qhov kev ua tau zoo kawg. Nws ua tau zoo hloov cov kev ntxhov siab los ntawm cov yas matrix uas tsis muaj zog mus rau lub zog sab hauv fibers, uas ua rau muaj zog loj, tawv, thiab tshwj xeeb tshaj yog cuam tshuam.
LFT ua li cas? Saib sai ntawm Pultrusion txheej txheem
Qhov zais cia kom khaws cov fibers ntev nyob hauv cov txheej txheem tsim khoom, hu uapultrusion.
Xav txog kev rub cov hlua txuas txuas ntxiv ntawm cov hlua fiber ntau (xws li cov hlua tuab) los ntawm da dej ntawm cov thermoplastic resin molten. Cov resin kiag li coats thiab impregnates cov fibers. Cov khoom sib xyaw no yog tom qab ntawd rub los ntawm kev tuag, txias, thiab chopped rau hauv pellets, txhua tus uas muaj cov fibers ntev.
Txoj kev no yog qhov sib txawv ntawm qhov yooj yim compounding siv rau SFT, qhov twg cov fibers chopped yog tov rau hauv molten yas, ib tug txheej txheem uas feem ntau lov cov fibers mus ntxiv. Pultrusion ua kom cov fibers nyob twj ywm ntawm lawv qhov ntev, npaj los tsim cov pob txha sab hauv tseem ceeb hauv koj qhov kawg.
LFT vs Lub Ntiaj Teb: Vim Li Cas Mus Ntev?
