Ntxiv cov teebmeem metallic lossis pearlescent rau cov khoom yas feem ntau yog nyob ntawm kev ntxiv cov xim tshwj xeeb xim masterbatches rau cov khoom siv yas, ua ke nrog cov txheej txheem tsim nyog, tshwj xeeb hauv - xim xim (cov xim sib xyaw).
Lub hauv paus ntsiab lus:Ua ntej- sib tov xim hlau los yog pearlescent pigments nrog yas resin, thiab tom qab ntawd tsim cov khoom hauv ib kauj ruam los ntawm kev txhaj tshuaj molding, extrusion, lossis lwm yam txheej txheem.
Qhov zoo:Cov txheej txheem yooj yim, tus nqi qis dua, ntau tus phooj ywg ib puag ncig (tsis muaj kev tshaj tawm - yuav tsum tau ua), thiab ua haujlwm ntev -.
Qhov tsis zoo:Hlau gloss feem ntau yog qis dua electroplating, thiab fusion kab tuaj yeem tshwm sim tau yooj yim vim cov xim tsis sib xws.
Tej kev siv:Automotive sab hauv thiab sab nrauv trim, cov khoom siv hauv tsev, cov khoom siv hluav taws xob, cov ntim khoom kom zoo nkauj.
Yuav kom ua tiav cov txiaj ntsig zoo pearlescent, peb lub ntsiab lus hauv qab no yog qhov tsim nyog:
Xaiv cov nyhuv pigments
Cov teebmeem hlau feem ntau yog siv flake-puabhlau pigmentsxws li txhuas hmoov; pearlescent teebmeem nyob ntawm cov xim nrog cov hlau oxide coatings rau saum npoo ntawm substrates xws li mica (natural lossis hluavtaws). Pigment particle loj thiab cov duab yog qhov tseem ceeb: qhov loj me me tuaj yeem ua rau muaj zog sparkle tab sis yuav txo qhov opacity; tshwj xeeb geometric duab tsim pab txo fusion kab.
Kev sib piv ntawm cov cob cob
Lub pob tshab ntawm cov khoom siv hauv paus ncaj qha cuam tshuam cov nyhuv:pob tshab los yog translucent resins(xws li pob tshab ABS, PC, PP) tso cai rau lub teeb kom nkag mus thiab cuam tshuam, ua kom zoo dua, sib sib zog nqus hlau lossis pearlescent nyhuv.
Tswj kev siv tshuab.
Qhov no yog lub hauv paus ntawm cov thev naus laus zis, tshwj xeeb tshaj yog rau hauv -pwm xim.
Mixing thiab dispersion:Nws yog ib qho tseem ceeb los xyuas kom meej tias cov pigments sib npaug sib npaug hauv cov resin kom tsis txhob agglomeration. Qee zaum, tshwj xeeb masterbatches yuav tsum tau.
Kev kub ceev thiab shear:Qhov kub thiab txias dhau los yog muaj zog shear force (xws li cov ntsia hlau ntau dhau) tuaj yeem ua rau cov qauv ntawm cov xim flake, ua rau txo qis gloss.
Kev daws qhov teeb meem "fusion line":
Cov kab fusion yog cov tsos mob tshwm sim ntau tshaj plaws hauv -pwm xim. Ntxiv nrog rau kev siv cov xim tsim tshwj xeeb, qhov teeb meem no tuaj yeem txo tau los ntawm kev txhim kho pwm tsim (xws li hloov lub rooj vag txoj haujlwm), txhim kho cov khoom ntws, thiab kho cov txheej txheem txhaj tshuaj molding (xws li kub thiab ceev).
