Cov iav fiber ntau ntxiv polymer matrix composites yog cov ntaub ntawv tseem ceeb hauv engineering, lawv yog cov khoom siv dav siv thoob ntiaj teb, feem ntau yog vim lawv qhov hnyav hauv kev ua ke nrog kev nruj nruj thiab lub zog.
Polyamide 6 (PA6) nrog 30% Iav Fiber (GF) yog ib qho ntawm cov khoom siv polymers ntau tshaj plaws vim nws cov txiaj ntsig zoo, txhim kho cov yam ntxwv zoo, kev ua haujlwm siab, kev ua haujlwm siab, lub zog tawg, rov ua dua tshiab, thiab lwm yam. lawv muab cov ntaub ntawv zoo tshaj plaws rau kev ua cov cuab yeej hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob engineering, thiab cov khoom siv tsheb.
Txawm li cas los xij, cov ntaub ntawv no kuj muaj qhov tsis zoo, xws li Cov txheej txheem ua haujlwm feem ntau yog txhaj tshuaj molding. Lub fluidity ntawm fiber-reinforced nylon tsis zoo, uas yooj yim ua rau kev txhaj tshuaj siab, kev txhaj tshuaj kub, kev txhaj tshuaj tsis txaus, thiab cov cim dawb radial tshwm rau ntawm qhov chaw, qhov tshwm sim feem ntau hu ua "floating fiber", uas yog tsis tsim nyog rau cov yas. qhov chaw uas zoo li yuav tsum tau nyob rau hauv cov txheej txheem txhaj tshuaj molding.
Thaum, nyob rau hauv cov txheej txheem ntawm kev txhaj tshuaj molded cov khoom, lubricants tsis tuaj yeem raug ntxiv ncaj qha los daws qhov teeb meem, thiab feem ntau, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov roj nplua nyeem hauv cov mis hloov ntawm cov khoom siv raw los xyuas kom meej tias cov iav fiber reinforcement yog txhaj molding zoo.
Silicone additiveyog siv los ua ib qho kev pab ua haujlwm zoo heev thiab cov roj nplua nyeem. Nws cov khoom siv silicone txhim kho cov khoom ntim khoom hauv cov ntawv sau thiab cov khoom ntws ntawm cov polymer yaj. Qhov no nce extruder throughput. Nws kuj txo lub zog xav tau rau kev sib xyaw ua ke, Feem ntau, qhov ntau npaum ntawm silicone additive yog 1 mus rau 2 feem pua. Cov khoom yog ib qho yooj yim rau pub nrog ib tug txheej txheem system thiab yog nkag mus rau hauv lub polymer sib tov ntawm ib tug ntxaib-ntsia hlau extruder.
Kev siv ntawmsilicone additivehauv PA 6 nrog 30% iav fiber ntau tau pom tias muaj txiaj ntsig zoo rau ntau yam kev siv. Los ntawm kev txo tus nqi ntawm cov fiber ntau tshaj tawm ntawm qhov chaw ntawm cov khoom siv, silicone additives tuaj yeem pab tsim kom muaj kev ua tiav zoo dua thiab txhim kho ntws. Tsis tas li ntawd, lawv tseem tuaj yeem pab txo qis warping thiab shrinkage thaum lub sijhawm tsim khoom thiab txo cov suab nrov thiab kev vibration thaum ua haujlwm. yog li no,silicone additivesyog ib txoj hauv kev zoo rau cov tuam txhab nrhiav kev txhim kho lawv cov khoom.
Tsim cov tswv yim kom txo qis Polyamide 6 PA6 GF30 iav Fiber raug
SILIKE Silicone MasterbatchLYSI-407 yog dav siv los ua cov khoom siv tau zoo rau PA6-tshaj cov khoom siv los txhim kho cov khoom ua haujlwm thiab qhov zoo ntawm qhov chaw, xws li cov peev txheej zoo dua, pwm filling & tso tawm, tsawg dua extruder torque, qis coefficient ntawm kev sib txhuam, ntau dua mar thiab puas. tsis kam.Ib qho tseem ceeb yuav pab daws cov teeb meem iav fiber ntau hauv PA6 GF 30 txhaj tshuaj molding.
