Nyob rau hauv lub tshav pob ntawm cov xim masterbatch ntau lawm, qhov sib ntxiv ntawm paraffin ciab thiabPE waxtuaj yeem txhim kho cov flowability ntawm cov khoom siv polymer.Los ntawm kev txhim kho lub wettability thiab dispersion ntawm pigments thiab lwm yam additives, cov kev ua tau zoo tuaj yeem txhim kho mus rau qhov sib txawv, uas yog qhov zoo rau kev txhim kho kev tsim khoom thiab qhov pom tseeb ntawm cov khoom extruded.Yog li ntawd, ntau lub chaw tsim khoom siv paraffin wax nrog lub melting point ntawm ib ncig ntawm 60 ℃ raws li ib tug dispersant los yog ua ke nrog polyethylene wax kom ntau lawm thiab txo nqi.Tam sim no peb soj ntsuam qhov kev ua tau zoo sib txawv ntawm ob los ntawm qhov kev xav ntawm kev siv tswv yim hauv kev ua xim masterbatch.

(1) Thermal kev ua haujlwm
Lub lubricating dispersant siv rau xim masterbatches yuav tsum muaj peev xwm tiv taus qhov kub thiab txias thiab tswj cov khoom thermal stability thaum lub sij hawm tsim cov xim masterbatches thiab molding ntawm cov khoom xim;Txwv tsis pub, cov dispersant siv rau gasification lossis decomposition yuav muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov xim masterbatch lossis cov khoom.Kev ua haujlwm kub ntawm cov xim masterbatches thiab cov khoom yog feem ntau ntawm 160-220 ℃.Peb tau ua kev sim isothermal thermogravimetric rau ntawmpolyethylene waxthiab paraffin ciab nrog lub melting point ntawm 60 ℃.Cov txiaj ntsig tau pom tias qis dua 200 ℃, paraffin wax thawb 9.57% ntawm nws qhov hnyav hauv 4 feeb, thiab qhov hnyav poob mus txog 20% ​​hauv 10 feeb.Los ntawm qhov kev xav ntawm kev tiv thaiv tshav kub ib leeg, polyethylene wax tuaj yeem pom cov cua sov zoo heev, thaum paraffin siv quav ciab nyuaj rau lav.Yog li ntawd, paraffin wax tsis haum rau siv raws li xim masterbatch dispersant.

(2) Dispersion kev ua tau zoo
Txhawm rau sib piv thiab txiav txim siab cov khoom tawg ntawm pe wax thiab paraffin wax, dub masterbatches tau npaj nrog ntau qhov sib txawv ntawm ob, thiab cov yeeb yaj kiab nyias nyias tau ua.Nyob rau hauv qhov sib ntxiv ntawm 0-7%, dub masterbatch tsis tu ncua nce los ntawm 36.7% nrog rau cov ntsiab lus ntawm polyethylene wax, qhia tias siab dua cov ntsiab lus polyethylene wax, qhov zoo dua qhov kev ua haujlwm ntawm cov pa roj carbon dub;Txawm li cas los xij, nyob rau hauv tib qhov sib ntxiv sib piv, cov masterbatch dub tau txo qis los ntawm 19.9% ​​nrog qhov nce ntawm paraffin, qhia tias cov ntsiab lus paraffin ntau dua, qhov kev ua haujlwm tsis zoo ntawm cov pa roj carbon dub.
Qhov no yog vim hais tias piv rau pe wax, paraffin wax yog feem ntau ua rau wetting carbon dub, tab sis tib lub sij hawm, nws txo cov viscosity ntawm lub system.Qhov qis viscosity zoo heev ua rau kev sib kis ntawm shear quab yuam thiab cuam tshuam nrog dispersion.Cov pa roj carbon dub yog coated los ntawm qhov chaw ntawm paraffin, tsim cov khoom loj dua cov pa roj carbon dub aggregates.Obviously, qhov kev cuam tshuam ntawm kev sib cais no zoo heev tshaj nws qhov tsis muaj zog ntawm kev sib koom ua ke ntawm cov aggregates.

Yog li ntawd, kev sib piv ntawm cov kev sim tau pom tau hais tias polyethylene wax muaj ib tug zoo lubricating thiab dispersing nyhuv ntawm carbon dub, thaum nyob rau hauv cov xim masterbatch, cov pa roj carbon dub ntxiv nrog paraffin wax yuav ua rau deteriorate.
