LGF PA66: Cov khoom siv lub teeb yuag

LGF PA66: Cov khoom siv lub teeb yuag

LGF PA66 compound resin (Long Glass Fiber Reinforced Polyamide 66) yog ib qho khoom siv zoo heev ({2}}cov khoom siv thermoplastic composite. Tsis zoo li cov ntaub ntawv luv luv iav fiber ntau ntxiv, cov iav fibers hauv LGF PA66 hais muaj qhov ntev tib yam li qhov ntev (feem ntau yog 10 hli - 12 hli lossis ntev dua). Cov qauv no endows nws nrog zoo heev mechanical zog.

LGF PA66 yog ib qho kev ua haujlwm siab -cov khoom siv yas sib xyaw. Nws yog tsim los siv cov iav fiber ntau qhov cuab yeej siv ntev ntev, thiab tswj kom muaj feem ntau ntawm cov fiber ntau ntev txawm tias tom qab txhaj tshuaj molding. Cov khoom no yog tsim tshwj xeeb rau cov ntawv thov kev lag luam uas xav tau lub zog siab, lub teeb yuag, tiv thaiv tshav kub, thiab tshuaj tiv thaiv corrosion. Nws tuaj yeem siv dav hauv tsheb, tsheb thauj mus los rau pej xeem, khoom siv hauv tsev, thiab cov khoom siv hluav taws xob thiab hluav taws xob.

LGF PA66 yog dab tsi?

LGF PA66 yog ib qho yas yas tsim los ntawm PA66 raws li cov matrix thiab ntxiv nrog cov iav ntev ntev (feem ntau 5-25 hli). Piv rau luv luv -fiber PA66, nws muaj zog dua cov qauv, cuam tshuam tsis kam thiab qhov ruaj khov.

Automotive Engineering

Cov ntsiab lus tseem ceeb: Mus dhau "hloov hlau nrog yas", ua tiav qhov sib npaug zoo ntawm cov qauv kev nyab xeeb thiab kev sib koom ua ke.

Rau kev lag luam tsheb, LGF PA66 yas pellet tsis yog ib qho cuab yeej rau kev txo qhov hnyav, tab sis yog cov khoom tseem ceeb rau kev paub txog kev tsim qauv thiab txhim kho NVH kev ua tau zoo ntawm tag nrho lub tsheb.

Muaj tseeb Cov Txheej Txheem Kev Ncaj Ncees Hloov

Ntev iav fibers tsim ib tug interlaced network nyob rau hauv lub tivthaiv, zoo ib yam li "reinforced qhob". Cov qauv no muab cov khoom siv muaj zog tshwj xeeb thiab tshwj xeeb modulus. Nyob rau hauv kev tsim ntawm pem hauv ntej module thav duab, sunroof thav ntawv, thiab txawm lub rooj zaum ncej, LGF PA66 tuaj yeem ncaj qha hloov tuag- cam khwb cia txhuas lossis hlau stamping, ua tiav qhov hnyav tsis tas yuav muaj kev tiv thaiv corrosion zoo li hlau.

Zoo heev -kub creep kuj:

Ua tsaug rau qhov txwv tsis pub siv cov fiber ntau ntev, LGF PA66 yas pellet nthuav tawm qhov zoo dua qhov ruaj khov ntawm qhov kub thiab txias piv rau cov khoom siv iav luv luv. Nws ua kom ntseeg tau tias cov khoom tswj xyuas qhov tseeb geometric qhov ntev thoob plaws hauv lub tsheb tag nrho lub neej voj voog, txawm tias nyob rau hauv qhov kub thiab txias siab, lav qhov kev txhim khu kev qha ntawm lub tshuab tshuab.

Passive Safety thiab Crash Zog Absorption:

Daim ntawv thov: Nrog rau cov kev xav tau ntau ntxiv rau kev tiv thaiv roj teeb hauv lub tsheb tshiab, LGF PA66 compound resin yog siv dav hauv cov roj teeb txhawb nqa thiab cuam tshuam cov kab teeb.

Qhov zoo: Thaum muaj kev sib tsoo, cov khoom siv iav luv luv yuav tawg sai sai; thaum LGF PA66 sib xyaw tuaj yeem nqus tau lub zog loj los ntawm kev rho tawm ntawm fibers, lawv tawg, thiab cov yas deformation ntawm cov resin. Txawm hais tias cov matrix tawg, cov fibers ntev tseem tuav cov fragments ua ke, tswj kev ncaj ncees ntawm cov qauv.

Industrial & Consumer khoom

Cov ntsiab lus tseem ceeb: "Durability" thiab "Sophistication" raws li tau hais tseg nyob rau hauv cov xwm txheej hnyav
Rau cov pab pawg no, cov ntaub ntawv yuav tsum tau ua qhov kev sim ntawm lub sijhawm thiab muab cov neeg siv nrog - kev ua haujlwm zoo.

Heev Durability

Tsawg- qhov kub kom zoo dua: Ntau yam khoom siv sab nraum zoov (xws li kev caij ski binding, railway fasteners) yuav tsum tau ua haujlwm hauv huab cua khov. Cov ntaub ntawv zoo ib yam yuav "kua" ntawm qhov kub thiab txias thiab tawg me ntsis. LGF PA66, nrog nws cov txheej txheem fiber ntau, tseem tuav cov kev cuam tshuam loj heev hauv qhov chaw ntawm -30 degree, kom ntseeg tau tias cov khoom tsis nkig tab sis tawv heev hauv cov dej khov thiab daus.
Los tiv thaiv- lub neej qaug zog: Cov khoom siv xws li cov twj tso kua mis muaj lub cev thiab cov cuab yeej hluav taws xob cov khoom siv hluav taws xob tau dhau ntau lab ntawm cov khoom sib hloov. Cov hlau tuaj yeem ua rau qaug zog tawg, tab sis LGF PA66 muaj kev tiv thaiv kev qaug zog zoo heev, tiv thaiv kev pib thiab nthuav tawm ntawm cov kab nrib pleb, ua kom lub neej ntev ntawm cov khoom siv.

Txhim kho cov neeg siv kev paub dhau los ntawm kev vibration damping:

Piv nrog rau kev sib kis nruj ntawm kev co los ntawm cov hlau, cov polymer matrix inherently muaj cov khoom damping. Los ntawm kev siv LGF PA66 los tsim cov casing, nws muaj peev xwm ua tau zoo nqus thiab txo qhov siab - zaus vibrations thiab suab nrov tsim los ntawm lub cev muaj zog, yog li pab txhawb kev nplij siab thiab kev ua haujlwm raug ntawm cov khoom siv tes tuav, thiab ua kom "zoo tshaj" ntawm cov khoom.

Kev zoo nkauj

Txawm hais tias cov iav iav ntev ntev yuav ua rau "floating fibers" (ua rau ntawm qhov chaw ntxhib), qhov zoo ntawm LGF PA66 tuaj yeem muab cov khoom zoo nkauj rau cov khoom pov thawj xws li siab - kawg ergonomic lub rooj zaum thiab drone caj npab. Nws txawm tshem tawm qhov xav tau rau kev pleev xim, ua rau nws ib puag ncig tus phooj ywg thiab txo cov nqi xa tawm - ua cov nqi.

Cov lus qhia ua haujlwm

Txoj kev ua: Siv qis- shear txhaj molding, tswj cov yaj ntws thiab fiber ntau orientation los xyuas kom meej cov khoom ntawm cov khoom.
Tsim kev tawm tswv yim: Siv cov cuab yeej txhawb nqa los txhim kho cov kabmob muaj peev xwm, tsim nyog npaj cov kev taw qhia fiber ntau, thiab txo cov kev ntxhov siab ntawm cov kaum ntse ntse thiab vuam kab.
Cia thiab tuav: Tsis txhob muaj qhov chaw ntub dej thiab khaws cov ntaub ntawv kom qhuav thaum lub sij hawm cia kom txhim khu kev ruaj ntseg ntawm kev txhaj tshuaj molding.
