Yog li ntawd, dispersibility plays lub luag haujlwm tseem ceeb hauv cov khoom yas zoo. Yog li, dab tsi raws nraim ua rau tsis zoo dispersibility ntawm xim masterbatches? Puas yog nws muaj teeb meem nrog cov xim masterbatch nws tus kheej? Cia peb txheeb xyuas qhov no kom ntxaws:
1. Kev cuam tshuam ntawm Pigment yam ntxwv: Pigment masterbatches yog qhov tseem ceeb siab -concentration pigment polymers. Ntau cov hmoov agglomerating ua ke tau yooj yim cuam tshuam rau dispersion. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov xim xws li titanium dioxide thiab carbon dub, uas muaj zog agglomeration zog thiab yog nquag mus clumping. Yog li ntawd, rationally xaiv hom thiab particle loj ntawm cov xim raws li cov neeg siv khoom xav tau thiab cov txheej txheem ntau lawm yog qhov tseem ceeb rau kev txhim kho cov dispersibility ntawm cov xim masterbatch.
2. Kev cuam tshuam hluav taws xob zoo li qub: Qee cov xim masterbatches tsis muaj cov tshuaj tiv thaiv zoo li qub. Thaum lub sij hawm tsim khoom, hluav taws xob zoo li qub tuaj yeem tsim tau yooj yim thaum lub sij hawm sib xyaw thiab nplawm ntawm cov xim masterbatch thiab yas raw khoom. Qhov no tuaj yeem ua rau tsis sib xws ntawm cov xim masterbatch hauv cov khoom siv raw, ua rau cov khoom tsis sib xws.
3. Kev cuam tshuam ntawm Melt Flow Rate (Melt Index): Qee cov neeg muab khoom xim xim masterbatch xaiv cov resins nrog cov kua nplaum siab (MFRs) ua cov khoom thauj mus rau kev ua haujlwm zoo dua. Txawm li cas los xij, MFR siab dua tsis yog ib txwm zoo dua; Nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog cov khoom ua tau zoo, qhov zoo ntawm qhov chaw, thiab cov kev xav tau ua. MFR uas tsawg dhau yuav ua rau nws nyuaj rau cov xim masterbatch kom tawg txaus hauv cov khoom tiav; thaum MFR uas siab dhau kuj tseem yuav cuam tshuam rau lwm yam khoom. Yog li ntawd, rationally tsim MFR ntawm cov xim masterbatch raws li cov yam ntxwv ntawm cov cab kuj thiab cov xim yog qhov tseem ceeb rau kev txhim kho dispersibility.
4. Kev cuam tshuam ntawm Kev Sib Txuas Ntxiv
Txhawm rau tswj cov nqi lossis ua kom cov khoom ua tau zoo, qee cov xim masterbatches yog tsim los nrog cov nqi ntxiv qis. Txawm li cas los xij, yog tias qhov sib piv sib ntxiv tsawg dhau, cov xim masterbatch nyuaj rau disperse tusyees hauv cov yas, yooj yim ua rau cov xim tsis sib xws.
5. Kev cuam tshuam ntawm Dispersion System
Thaum lub sij hawm tsim cov xim masterbatches, dispersants thiab lubricants feem ntau yog ntxiv los pab cov xim hmoov disperse tusyees. Yog tias cov dispersant tsis raug xaiv kom raug, nws tsis tuaj yeem ua rau cov hmoov agglomerates hauv cov xim masterbatch, uas ua rau tsis zoo dispersibility.
6. Kev cuam tshuam ntawm qhov sib txawv
Txhawm rau txhim kho lub zog zais, siab - xim xim hmoov, xws li titanium dioxide (qhov ceev kwv yees li 4.0 g / cm³), feem ntau ntxiv rau cov xim masterbatches. Qhov sib txawv ntawm qhov sib txawv no tuaj yeem yooj yim ua rau cov xim masterbatch nyob rau hauv qab thaum nplawm, tsis sib tov tag nrho nrog cov khoom siv yas, ua rau cov khoom tsis sib xws.
7. Kev cuam tshuam ntawm kev xaiv cov cab kuj
Cov cab kuj ntawm cov xim masterbatch yog siv los tuav cov xim hmoov thiab lwm yam khoom ntxiv. Nws hom, ntau yam, qauv, yaj Performance index, thiab morphology ncaj qha cuam tshuam rau kev ua tau zoo thiab dispersion nyhuv ntawm cov xim masterbatch. Siv cov khoom siv polyolefin ua piv txwv, kev xaiv ntawm PP, PE, lossis EVA ua tus nqa khoom, kev siv ib tus neeg nqa khoom lossis kev sib xyaw ntawm cov nqa khoom, thiab cov qib tshwj xeeb, yaj Performance index, thiab daim ntawv (hmoov lossis granules) ntawm cov cab kuj yuav cuam tshuam rau qhov zoo ntawm cov khoom kawg.
8. Kev cuam tshuam ntawm kev tsim khoom thiab kev ua tiav Kev tsim cov xim masterbatch muaj ntau yam txheej txheem, los ntawm kev xaiv cov khoom sib xyaw thiab cov txheej txheem, mus rau cov khoom siv granulation, ntsia hlau sib dhos, txheej txheem granulation, thiab txawm tias cov txheej txheem txias. Qhov sib txawv ntawm ib qho ntawm cov theem no yuav cuam tshuam qhov kev ua tau zoo kawg ntawm cov xim masterbatch.
