Yuav ua li cas xaiv polyethylene wax rau cov xim masterbatches?

Polyethylene quav ciab, ua ib yam khoom siv tshuaj zoo, siv dav hauv kev ua cov yas thiab roj hmab thiab hauv kev tsim cov txheej thiab cov kua mem. Polyethylene quav ciab yog sib xws nrog polyethylene thiab polypropylene, thiab tuaj yeem txhim kho qhov fluidity ntawm polyethylene, polypropylene thiab ABS thiab kev demoulding ntawm polymethyl methacrylate thiab polycarbonate. Hauv kev ua PVC, piv nrog microcrystalline quav ciab, polyethylene quav ciab muaj cov nyhuv lubrication sab nraud muaj zog dua. Tsis tas li ntawd, polyethylene quav ciab kuj tseem siv tau rau hauv cov kua mem, txheej, ntawv thiab cov nplaum kub yaj.

Polyethylene quav ciabyog tshwj xeeb rau kev ua masterbatch thiab yog ib qho khoom siv tseem ceeb los daws qhov teeb meem ntawm cov xim lossis cov khoom sib xyaw hauv masterbatches. Cov polyethylene wax xaiv yuav tsum muaj kev sib raug zoo nrog cov resin kom tsis txhob muaj kev hloov pauv; muaj kev ruaj khov thermal zoo heev kom tsis txhob muaj kev lwj hauv kev ua tom ntej thiab teeb meem zoo.

Polyethylene quav ciabfeem ntau yog siv rau hauv polyolefin masterbatches, suav nrog polyethylene masterbatches, polypropylene masterbatches thiab EVA masterbatches.

Cov tshuaj polyethylene homopolymerized feem ntau yog siv rau hauv polyolefin masterbatches ua cov xim ntub thiab dispersing tus neeg sawv cev. Nws yog siv rau kev ntub, dispersing, sib tov thiab stabilization ntawm cov xim tom qab dispersion.

Nyob rau hauv lubcov tshuaj masterbatch, qhov ntau ntawm cov xim lossis cov khoom sau loj heev, ntxiv rau qhov loj me ntawm cov xim thiab cov khoom sau no me heev, nyob rau hauv qhov ntau ntawm 0. 01 ~ 1. 0μm, yog li nws yooj yim rau agglomerate. Los ntawm kev ntxiv homopolymerized polyethylene wax, cov polyethylene wax yaj hauv qee qhov kub thiab tuaj yeem ntub cov xim lossis cov khoom sau nto. Qhov hu ua pigment wetting yog cov txheej txheem uas cov polyethylene wax molten tau tuav ze rau ntawm qhov chaw ntawm cov xim thiab nkag mus rau hauv cov qhov me me ntawm cov xim los ntawm capillary kev ua haujlwm los hloov huab cua thiab noo noo hauv nws qhov chaw qub.

Qhov pib ntub ntawm cov xim yog qhov tseem ceeb rau qhov tshwm sim ntawm cov xim tawg, tab sis cov txheej txheem no feem ntau ua tiav hauv ob peb kauj ruam yooj yim thiab yog li ntawd yooj yim tsis quav ntsej. Tus neeg sawv cev ntub yuav tsum ua kom txaus capillary nkag mus ntawm cov microgaps hauv cov xim sib sau ua ke, vim yog capillary nkag mus, qhov sib koom ua ke ntawm cov xim sib sau ua ke raug txo qis, thiab nws yooj yim tsoo thiab ua kom zoo nyob rau hauv qhov kev ua ntawm lub zog shear. Yog li ntawd, qhov ntub thiab qib ntawm capillary nkag mus ntawm cov xim ua lub luag haujlwm txiav txim siab hauv tag nrho cov nqi tawg thiab qhov zoo ntawm cov xim sib sau ua ke. Yog tias qhov cuam tshuam ntub zoo, cov xim sib sau ua ke tuaj yeem yooj yim tawg txawm tias muaj qhov shear tsis muaj zog. Thaum cov xim sib sau ua ke raug tawg, cov quav ciab npog qhov chaw tshiab tsim tsis muaj xim thiab ruaj khov cov xim sib sau ua ke, uas yog li cas polyethylene quav ciab ua haujlwm ua tus neeg sawv cev ntub dej ntawm cov xim sib cais.

Yog li ntawd, cov ntsiab cai ntawm polyethylene wax ua tus masterbatch dispersant raug xaiv raws li hauv qab no.

Qhov hnyav molecular tsim nyog - viscosity ntawm polyethylene wax.

Kev faib tawm ntawm qhov hnyav molecular nqaim dua.

Muaj peev xwm ntub dej zoo dua.

Kev ua haujlwm kub dua.
