Qhia LGF TPU Khoom hauv GF TPU Field
Iav Fiber-Reinforced Thermoplastic Polyurethane (GF TPU) yog siab-cov khoom siv sib xyaw ua ke uas ingeniously sib xyaw ua ke zoo heev elasticity, hnav tsis kam, thiab yooj ntawm thermoplastic polyurethane (TPU) nrog lub zog siab, rigidity, thiab dimensional stability ntawm iav fibers (GF). Qhov tshwm sim ntawm cov khoom siv no tau nthuav dav qhov kev thov ciam teb ntawm engineering plastics, tshwj xeeb tshaj yog nyob rau hauv cov kev xav tau uas "rigidity thiab yooj" yuav tsum tau. GF TPU composite tam sim no tau dhau los ua qhov kev daws teeb meem tseem ceeb los hloov cov hlau tsoos, roj hmab, thiab lwm yam yas yas.
Luv iav Fiber (SGF) vs. Ntev iav Fiber (LGF)
Nov yog qhov tseem ceeb ntawm kev lag luam sib txawv:
SGF TPU (luv iav fiber ntau):Qhov ntev ntawm fiber ntau yog tsawg dua 1 hli. Nws yog ib qho yooj yim rau txheej txheem thiab muaj qhov zoo ntawm qhov chaw tiav, tab sis kev txhim kho kev ua tau zoo yog txwv. Nws feem ntau txhim kho rigidity.
LGF TPU (ntev iav fiber ntau):Qhov ntev fiber ntau tuaj yeem khaws cia ntawm 5 hli lossis ntau tshaj 25 hli (hauv qhov kawg ntawm cov khoom). LGF tsim ib qho peb - lub hauv paus qauv qauv nyob rau hauv cov khoom, txhim khu kev cuam tshuam lub zog (Impact Strength), creep resistance (Creep Resistance), thiab qaug zog durability (Fatigue Durability). LGF TPU cov khoom yog lub zog tseem ceeb rau kev ua tiav "hloov pauv".
GF TPU zoo rau dab tsi?
Cov kev cuam tshuam zoo tshaj plaws: Thaum cov khoom tiv thaiv raug cuam tshuam, qhov peb - cov qauv fiber ntau tuaj yeem cuam tshuam lub zog cuam tshuam rau lub ntim loj dua rau kev sib kis thiab kev nqus, thiab tiv thaiv kev nthuav dav ntawm microcracks.
Kev tiv thaiv zoo heev - xeb kev ua haujlwm: Nyob rau hauv ntev - lub sij hawm tsis tu ncua loads (xws li bolt preload lossis nruam load-cov kabmob), cov fiber ntau matrix ntawm LGF tuaj yeem "txhawb" tag nrho cov qauv, cuam tshuam qhov ntws ntawm cov polymer matrix, tso cai rau cov khoom siv los tswj nws cov duab thiab preload quab yuam ntev.
Kev qaug zog zoo thiab ua haujlwm ntev: Thaum raug rau ntau lab lub voj voog ntawm kev thauj khoom (xws li kev vibration, khoov), lub network fiber ntau ntawm LGF tuaj yeem cuam tshuam qhov pib thiab nthuav tawm ntawm qaug zog tawg, ua rau nws lub neej kev pab ntau tshaj li ntawm SGF cov ntaub ntawv sib xyaw. Nws yog qhov tsim nyog rau cov khoom siv hluav taws xob sib kis tau zoo lossis kev co ib puag ncig.
Kev sib tw qis dua thiab siab dua qhov ruaj khov: Txawm hais tias tag nrho cov iav fibers txo cov coefficient ntawm thermal expansion (CLTE), cov fibers ntev ntawm LGF cuam tshuam rau peb ntau dua - qhov ntev thiab random yam nyob rau hauv cov pwm kab noj hniav, ua rau cov nqi sib xws hauv FD thiab TD cov lus qhia. Qhov no txo qis cov khoom tiv thaiv warping, ua rau nws tshwj xeeb tshaj yog tsim rau kev tsim cov khoom loj thiab meej.

LGF TPU: Kev Sib Tw thiab Kev Tswj Xyuas Kev Ua Haujlwm
Tseem ceeb heev: ziab
TPU muaj cov khoom muaj zog hygroscopic. Yog tias cov dej noo tsis raug tshem tawm kom txaus ua ntej ua tiav, thaum lub sij hawm siab -kub melting txheej txheem, cov ya raws yuav hydrolyze TPU polymer chains, uas ua rau:
Hydrolysis degradation: Qhov hnyav molecular txo qis, thiab cov khoom siv kho tshuab raug puas tsuaj loj.
Cov khoom tsis xws luag: npuas tshwm, thiab txawm tias (hauv LGF TPU) cov fibers yuav raug nthuav tawm. Yog li ntawd, siv lub tshuab ziab khaub ncaws kom zoo rau ob peb teev ua ntej- ziab yog qhov yuav tsum tau ua.
Hnav thiab Shear
Screw hnav: iav fiber ntau yog cov khoom siv abrasive heev. Thaum ua tiav GF TPU compound resin, yuav tsum siv cov ntsia hlau tawv thiab rov qab valve (xws li cov ntsia hlau bimetallic) yuav tsum tau siv; txwv tsis pub, cov kab ntau lawm lifespan yuav luv heev.
Tswj shear: Ntau cov ntsia hlau sib hloov ceev thiab rov qab siab tuaj yeem ua rau muaj zog shear quab yuam, uas ua rau tuag taus hauv LGF TPU kev sib xyaw ua haujlwm - nws yuav cuam tshuam ntau dhau rau cov fibers ntev, ua rau lawv poob qhov zoo ntawm LGF. Yog li ntawd, "tsawg shear, qis rov qab siab" ua qhov rais yuav tsum tau txais yuav.
Pwm Tsim thiab Txhaj Tshuaj
Gate Design: Txoj hauj lwm thiab qhov loj ntawm lub rooj vag ncaj qha txiav txim siab cov txheej txheem melt filling, uas nyob rau hauv lem txiav txim siab qhov kawg orientation ntawm fibers nyob rau hauv lub tivthaiv (raws li tau hais ua ntej, qhov no yog anisotropy). Pwm venting kom zoo yuav tsum tau siv los tiv thaiv kev kub nyhiab lossis tsis txaus los ntawm cov pa roj (xws li cov khoom seem hauv cov khoom siv).
Surface Appearance: GF TPU yas pellet feem ntau nthuav tawm qhov tshwm sim "floating fiber", uas ua rau lub ntsej muag ntxhib. Qhov no txwv tsis pub nws daim ntawv thov ncaj qha rau A- qib cov yam ntxwv zoo li qub thiab feem ntau yuav tsum muaj kev tshaj tawm - tshuaj tsuag lossis siv cov kev hloov kho tshwj xeeb (xws li ntxiv cov roj nplua nyeem).
LGF TPU yas pellet yog ib qho khoom siv zoo heev, deb ntawm qhov yooj yim "yas nrog ntxiv iav fibers". Nws tus nqi yog nyob rau hauv precisely ntsuas rigidity, toughness, damping, thiab durability. Kev nkag siab zoo ntawm cov tshuaj sib txawv ntawm polyester thiab polyether, microstructure ntawm LGF / SGF, cov qauv tsim los ntawm anisotropy, thiab kev ua haujlwm nruj yog qhov tseem ceeb rau cov lag luam kom ua tiav qhov kev siv siab no - cov khoom ua tau zoo li lwm txoj hauv kev hlau, txo cov nqi, thiab ua tiav cov khoom lag luam.
