Taw qhia: Qhov Kev Sib Tw Tsis Txaus ntawm PA / GF Cov Khoom Siv
Cov iav fiber ntau reinforced polyamides (PA / GF) yog lub hauv paus hauv kev tsim khoom niaj hnub no vim lawv qhov tshwj xeeb txhua yam muaj zog, kub tsis kam, thiab qhov ruaj khov. Los ntawm cov khoom siv hauv tsheb thiab cov neeg siv khoom siv hluav taws xob mus rau cov qauv hauv aerospace thiab cov tshuab ua haujlwm, PA / GF cov ntaub ntawv tau siv dav hauv cov ntawv thov kev ua haujlwm siab uas yuav tsum tau ua kom muaj zog, precision, thiab kev ntseeg tau.
Txawm hais tias cov txiaj ntsig zoo li no, PA / GF cov ntaub ntawv nthuav tawm cov teeb meem tsis tu ncua uas tuaj yeem cuam tshuam kev tsim khoom, khoom zoo, thiab kev siv kawg. Cov ntsiab lus mob tshwm sim muaj xws li warpage, tsis zoo melt flow, cuab yeej hnav, thiab iav fiber ntau raug (floating fibers). Cov teeb meem no nce cov nqi seem, nce cov nqi tsim khoom, thiab xav tau ntxiv tom qab ua tiav - cov kev sib tw uas nquag cuam tshuam rau R & D, ntau lawm, thiab pab pawg muag khoom zoo ib yam.
Kev nkag siab thiab daws cov teeb meem no yog qhov tseem ceeb rau cov tuam txhab lag luam txhawm rau ua kom muaj peev xwm ntawm PA / GF cov ntaub ntawv thaum tswj kev ua haujlwm tau zoo thiab ua tau raws li cov qauv nruj.
Pain Point 1: Complex and Hard-to-Control Processing
Warpage thiab Deformation
PA / GF cov ntaub ntawv yog cov anisotropic heev vim yog kev taw qhia ntawm iav fibers. Thaum lub sij hawm txias, tsis sib xws shrinkage feem ntau ua rau warpage nyob rau hauv loj los yog geometrically complex Cheebtsam. Qhov no cuam tshuam qhov tseeb qhov tseeb, nce cov khoom seem thiab rov ua haujlwm dua, thiab siv sijhawm thiab cov peev txheej. Rau kev lag luam xws li automotive thiab aerospace, qhov uas nruj kam rau ua yog qhov tseem ceeb, txawm tias me me warpage tuaj yeem ua rau muaj kev tsis lees paub.
Poob Melt Flow
Qhov sib ntxiv ntawm cov iav fibers ua rau kom yaj viscosity, tsim kom muaj kev sib tw flowability thaum txhaj tshuaj molding. High melt viscosity tuaj yeem ua rau:
• Kev txhaj tshuaj luv luv
• Weld kab
• Ntog teeb meem
Cov teeb meem no yog teeb meem tshwj xeeb tshaj yog rau cov phab ntsa nyias nyias los yog qhov chaw nrog cov pwm tsim pwm. High viscosity kuj xav tau kev txhaj tshuaj ntau dua, nce kev siv zog thiab kev ntxhov siab ntawm cov khoom siv molding.
Accelerated Tool Hnav
Cov iav fibers yog abrasive thiab tawv, nrawm hnav ntawm pwm, khiav, thiab nozzles. Hauv kev txhaj tshuaj molding thiab 3D luam ntawv, qhov no ua rau lub neej luv luv, nce nqi kho, thiab tuaj yeem txo cov sijhawm ua haujlwm. Rau 3D luam ntawv, filaments uas muaj PA / GF tuaj yeem hnav cov nozzles, cuam tshuam rau ob qho tib si zoo thiab dhau los.
Tsis txaus Interlayer Bonding (rau 3D Printing):
Hauv kev tsim cov khoom siv ntxiv, PA / GF filaments tuaj yeem muaj kev cuam tshuam tsis muaj zog ntawm cov txheej txheem thaum luam ntawv. Qhov no ua rau txo cov khoom siv hluav taws xob ntawm cov khoom luam tawm, ua rau lawv tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog thiab kav ntev.
Pain Point 2: Cov iav fiber ntau raug thiab nws qhov cuam tshuam
Cov iav fiber ntau raug, tseem hu ua "floating fibers," tshwm sim thaum fibers protrude los ntawm polymer nto. Qhov tshwm sim no tuaj yeem cuam tshuam tsis zoo rau kev zoo nkauj thiab kev ua haujlwm:
Cov tsos mob tshwm sim:Qhov saum npoo zoo li ntxhib, tsis sib xws, thiab npub. Qhov no tsis tsim nyog rau cov ntawv thov uas xav tau kev pom zoo, xws li tsheb sab hauv, khoom siv hluav taws xob, thiab cov khoom siv.
Tsis zoo tactile xav:Rough, scratchy nto txo cov neeg siv kev paub thiab pom cov khoom zoo.
Txo Durability:Exposed fibers ua raws li kev ntxhov siab concentrators, txo lub zog saum npoo thiab puas ua hauj lwm. Nyob rau hauv ib puag ncig hnyav (piv txwv li, av noo lossis tshuaj lom neeg raug mob), fiber ntau raug ua kom cov khoom laus thiab kev ua haujlwm tsis zoo.
Cov teeb meem no tiv thaiv PA / GF cov ntaub ntawv los ntawm kev ncav cuag lawv lub peev xwm, yuam cov tuam txhab lag luam kom muaj kev cuam tshuam ntawm qhov zoo, kev zoo nkauj, thiab kev ua haujlwm zoo.
Cov kev daws teeb meem tshiab rau PA / GF Cov Txheej Txheem Ua Haujlwm
Kev nce qib tsis ntev los no hauv cov ntaub ntawv tshawb fawb, thev naus laus zis ntxiv, thiab kev tsim vaj tsev sib txuas muab cov tswv yim daws teeb meem rau cov teeb meem ntev ntev. Los ntawm kev sib koom ua ke hloov kho PA / GF tebchaw, silicone-raws li additives, thiab fiber-matrix compatibility enhancers, manufacturers yuav txo tau warpage, txhim kho yaj ntws, thiab txo cov iav fiber ntau raug.
1. Cov khoom siv qis-Warp PA/GF
Tsawg-warp PA / GF cov ntaub ntawv tshwj xeeb yog tsim los hais txog warpage thiab deformation. Los ntawm optimizing:
• Hom iav fiber ntau (luv, ntev, lossis txuas ntxiv fibers)
• Fiber ntev faib
• Cov thev naus laus zis kho deg
• Resin molecular qauv
cov formulations txo cov anisotropic shrinkage thiab cov kev ntxhov siab sab hauv, kom ntseeg tau tias qhov ruaj khov ntawm txoj kev txhaj tshuaj molded qhov chaw. Cov qauv tsim tshwj xeeb PA6 thiab PA66 qib ua kom pom kev txhim kho deformation tswj thaum lub sij hawm txias, tswj kom nruj nruj thiab zoo ib yam.
2. High-Flow PA / GF cov ntaub ntawv
High-flow PA / GF cov ntaub ntawv tiv thaiv cov dej ntws tsis zoo los ntawm kev sib xyaw:
