Cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb siv rau kev sib txuas cov hlau nplaum yog submicron grain alloy hmoov, uas tso cai rau ib qho yooj yim tawg cov hmoov hlau alloy rau qhov kev faib loj uas xav tau rau kev sau thiab tsim, thiab tom qab ntawd sib tov lossis sib xyaw nrog cov nplaum. Raws li qhov sib txawv ntawm lub cev lossis tshuaj lom neeg cov khoom ntawm cov nplaum thiab cov txheej txheem tsim, kev sib xyaw sib txawv thiab kev sib xyaw yog xav tau.
Compression forming hlau nplaum
Qhov feem pua ntawm cov hmoov sib nqus yog 96 feem pua ~ 98 feem pua (feem ntau), cov nplaum siv cov thermosetting resin (feem ntau epoxy) ntxiv rau tus neeg sawv cev kho, yaj cov resin thiab curing agent nrog cov kuab tshuaj organic thiab sib tov sib npaug, thiab tom qab ntawd ntxiv cov hmoov sib nqus rau hauv tov thiab do tag nrho, kom cov hmoov hlau nplaum sib npaug sib npaug thiab sawv hauv qhov kev daws teeb meem, yog li ntawd cov nplaum nplaum hauv cov tshuaj ua ib txheej zaj duab xis rau saum npoo ntawm cov hmoov sib nqus. Tom qab ntawd cov kuab tshuaj organic yog volatilized los ntawm cua sov lossis ntuj ziab, thiab tom qab ntawd cov hmoov qhuav thiab sib nqus sib nqus tau tawg mus rau qhov xav tau qhov loj me, uas tuaj yeem ua rau cov txheej txheem tom ntej. Txhawm rau txhim kho kev sau, kev taw qhia thiab kev cog lus ntawm cov khoom sib nqus thiab txhim kho lub zog ntawm cov hlau nplaum, nws yog ib qho tsim nyog yuav tsum tau ua kev sib txuas ntawm cov khoom sib nqus ua ntej sib tov, lossis ntxiv cov roj nplua nyeem tom qab sib tov crushing.
Txhaj lossis extrusion ua hlau nplaum
Kev siv cov thermoplastic resin, mus rau qhov loj kom ntev mus rau kev siv cov yas particle sib xyaw tshuab, thiab qhov sib txawv loj tshaj plaws nrog kev lag luam yas yog nws cov khoom ntim siab, kev hloov kho yas dav dav ntawm iav fiber, carbon fiber los yog lwm yam inorganic filler ntim piv yog 40 feem pua ~ 50 feem pua , thiab kev sib txuas ntawm lub ntiaj teb tsis tshua muaj hlau nplaum nyob rau hauv thiaj li yuav tau txais kev ua tau zoo, qhov kev faib ua feem no yuav siab li 80 feem pua, yog li cov khoom siv kho tshuab ua kom zoo dua qub, yuav tsum tau nce qhov ntev ntawm txoj kab uas hla. , nyob rau hauv thiaj li yuav ua rau lub grain tag nrho plasticized, sib tov thiab kev tawm dag zog, tab sis kuj rau cov neeg kho tshuab loj coj mus rau lub nto hardening kev kho mob ntawm nws qhov chaw. Xav txog qhov oxidation ntawm cov hmoov sib nqus thiab cov resin deterioration los ntawm kev kub kub sib tov thiab cov txheej txheem tom ntej, nrog rau kev txhaj tshuaj / extrusion ua ntawm granule nrog siab filling piv, tsim nyog xaiv yuav tsum tau ua nyob rau hauv kev sib xyaw ntawm resin thiab ntau yam additives thiab sib tov txheej txheem. .
