Hauv kev ua haujlwm siab -kev ua tau zoo hloov cov yas, cov khoom siv feem ntau siv zog rau "nyuaj, muaj zog dua, thiab kub dua- tiv taus", xws li LGF-PP lossis LGF-PA. Txawm li cas los xij, qhov tshwm sim ntawm LGF-TPU (Long Glass Fiber Reinforced Thermoplastic Polyurethane) tau rhuav tshem qhov kev xav hauv kev xav tias "siab zog" thiab "siab tawv" tsis tuaj yeem ua tiav ib txhij.
Vim li cas LGF TPU tsim los daws qhov teeb meem?
Txhawm rau nkag siab LGF-TPU yas pellet, ib qho yuav tsum xub nkag siab nws cov khoom siv hauv paus - TPU (thermoplastic polyurethane). TPU muaj npe nrov rau nws cov elasticity zoo heev, hnav tsis kam, thiab roj tsis kam, thiab feem ntau suav hais tias yog cov khoom "mos".
Txawm li cas los xij, hauv ntau qhov xwm txheej (xws li lub kaus mom kev nyab xeeb, cov khoom siv tshuab, cov khoom siv ua kis las), TPU ntshiab yog mos heev thiab tsis muaj kev txhawb nqa; Thaum cov khoom siv tawv tawv tawv (xws li nylon, PP) yog qhov nyuaj txaus, lawv tuaj yeem tawg ntawm qhov kub thiab txias thiab tsis muaj kev ntxhib los mos thiab ua haujlwm zoo.
LGF-TPU (ntev iav fiber reinforced thermoplastic polyurethane) compound resin tshwm sim thaum lub sijhawm. Nws siv cov "rub cov txheej txheem" (Pultrusion) rau immerse tas mus li iav fibers thiab kaw lawv nyob rau hauv lub TPU matrix.
Qhov txawv tseem ceeb:Tsis zoo li luv iav fibers (SGF), qhov ntev ntawm LGF feem ntau yog khaws cia ntawm 5-25 hli (nrog ntev ntev khaws cia hauv cov khoom kawg).
Microstructure:Cov fibers ntev yog intertwined nyob rau hauv lub TPU matrix, ua ib tug peb -dimensional "skeletal network".
Cov pob txha pob txha no ua rau cov khoom siv nrog cov rigidity zoo ib yam li cov hlau, thaum TPU matrix khaws cov kev yooj yim rau kev nqus lub zog. Nws zoo li kev cog cov pob txha muaj zog (LGF) hauv cov nqaij mos (TPU polymer).
LGF TPU: Hauv -Qhov Kev Ntsuas Qhov Ua Tau Zoo
Hauv kev sib pauv kev lag luam, peb yuav tsum tsis txhob tsom mus rau cov ntaub ntawv nkaus xwb, tab sis kuj tseem ua tib zoo saib xyuas cov kev coj cwj pwm ntawm lub cev tom qab cov ntaub ntawv. Cov kev sib tw tseem ceeb ntawm LGF-TPU yog tshwm sim hauv qhov sib npaug ntawm qhov loj me hauv qab no:
1. Ultra-siab qaug zog thiab kev ua haujlwm zoo
Qhov no yog qhov tshwj xeeb tshaj plaws ntawm LGF-TPU piv rau LGF-PP/PA. Nyob rau hauv ib puag ncig nrog rov khoov thiab siab - zaus vibration, cov ntaub ntawv uas muaj zog rigidity ntau yuav tsim micro- tawg thiab nthuav. Txawm li cas los xij, LGF-TPU siv lub siab elasticity ntawm matrix kom tshem tawm kev ntxhov siab thiab tiv thaiv kev tawg tawg.
2. Muaj kev cuam tshuam tsis zoo ntawm qhov kub thiab txias
Ordinary engineering plastics nyiam ua nkig (yuav hloov mus rau iav) nyob rau hauv qis - qhov kub thiab txias thiab tawg yooj yim thaum cuam tshuam. TPU nws tus kheej muaj qhov ua tau zoo heev qis- qhov kub thiab txias, thiab ua ke nrog kev txhawb nqa ntawm cov iav fibers ntev, LGF-TPU tseem tuaj yeem tuav cov tawv tawv heev thiab muaj kev cuam tshuam hauv qhov chaw khov.
3. Coexistence ntawm Rigidity thiab mos kov
Feem ntau, qhov saum npoo ntawm cov ntaub ntawv nrog ntxiv iav fibers ua ntxhib thiab tawv (fiberglass ntab teeb meem). Txawm li cas los xij, LGF-TPU, vim yog cov yam ntxwv ntawm nws cov matrix, muaj peev xwm tswj tau lub siab modulus (tsis kam mus rau deformation) thaum tseem tso cai rau saum npoo ntawm kev txhaj tshuaj- cov khoom molded kom tuav tau qhov muag muag, thiab nws kuj muaj qee lub suab nrov txo thiab kev poob siab ua haujlwm.
4. Exceptional creep kuj
Piv rau TPU tsis hloov kho, cov iav ntev fiber ntau cuam tshuam qhov zawv zawg ntawm cov saw hlau polymer. Qhov no txhais tau hais tias thaum raug qhov hnyav tas mus li-cov kabmob, cov khoom ua los ntawm LGF-TPU yuav tsis raug deformation mus tas li, tsis zoo li cov roj hmab zoo tib yam lossis yas.
Kev lag luam qhov chaw ntawm GF TPU Khoom
Thaum qhia LGF-TPU compound resin rau cov neeg siv khoom, peb tsis yog muag khoom xwb, tab sis muab lwm txoj hauv kev rau cov khoom siv.
1. Hloov cov hlau (yas hloov hlau / aluminium)
Cov kev sib tw: Cov hlau hnyav, muaj cov nqi ua haujlwm siab, thiab tsis muaj corrosion-resistant.
Qhov zoo ntawm LGF-TPU: Nws qhov ntom ntom yog qis dua li cov hlau, thiab nws tuaj yeem ua pwm los ntawm kev txhaj tshuaj molding hauv ib kauj ruam, txo cov nqi tsim khoom thiab qhov hnyav, thaum tseem muaj lub zog txaus los hloov qee cov aluminium alloy castings.
2. Hloov mus rau cov txheej txheem molding theem nrab ntawm "nyuaj yas + mos encapsulation roj hmab"
Cov Kev Sib Tw: Cov txheej txheem ib txwm muaj yuav tsum tau txhaj tshuaj thawj zaug (xws li nylon), thiab tom qab ntawd npog nws nrog ib txheej ntawm cov roj hmab muag (TPE / TPU). Cov txheej txheem yog complex, thiab cov adhesion yog nquag mus ua tsis tiav. Qhov zoo ntawm LGF-TPU: Nws yog inherently ib "cov khoom muag nrog inherent rigidity" los yog ib tug "hard material with inherent toughness", thiab tuaj yeem ncaj qha molded nyob rau hauv ib txoj kev, simplifying cov txheej txheem ntau lawm.
GF TPU siv rau dab tsi?
Daim ntawv thov ntawm LGF-TPU composite tsis txwv rau ib qho kev lag luam tshwj xeeb. Nws tuaj yeem pom hauv txhua qhov chaw uas muaj "lub zog thiab sib npaug":
High- cov ntaub ntawv khau kawg (core market):
Safety ntiv taw (Safety Toe): Ib qho kev hloov rau cov ntiv taw steel. LGF-TPU yas pellet tsis tsuas yog dhau qhov kev sim tiv thaiv- tawg, tab sis kuj yog sib dua li cov ntiv taw steel, tsis ua kom sov (kwv taw sov rau lub caij ntuj no), thiab vim nws qhov hnyav, nws muaj qhov chaw rov qab los tom qab hnyav hnyav thiab tsis zoo li yuav ntxiab cov ntiv taw.
Midsole txhawb phaj (Shanks): Muab kev txhawb nqa koov thiab tiv thaiv kev qaug zog tawg.
Automotive kev lag luam:
Sab hauv cov khoom siv: Hloov lub hauv paus, qhov rooj kov ncej. Lawv yuav tsum muaj lub zog ntawm cov qauv thiab yuav tsum tsis txhob tsim cov khoom tawg yooj yim uas tuaj yeem ua rau raug mob thaum tawg.
Chassis system: Shock absorption tsis thaiv, plua plav npog clamp.
Kev lag luam thiab cov cuab yeej:
Hnyav-cov casters: Lawv tuaj yeem nqa qhov hnyav dua piv rau cov log TPU ntshiab, thiab nyob ntsiag to thiab tsis tshua muaj kev puas tsuaj hauv pem teb piv rau cov log nylon. Cov cuab yeej hluav taws xob tuav: tiv thaiv kev tawg thaum muaj kev cuam tshuam, muab kev tuav zoo, thiab txo qis kev sib kis ntawm lub cev muaj zog vibrations.
