polyethylene ciab yog qhov hnyav molecular (< 1000) polyethylene, uas yog ib qho kev pabcuam hauv kev lag luam yas. Kev siv polyethylene wax nyob rau hauv cov yas extrusion tuaj yeem txhim kho cov ntaub ntawv fluidity, nce ntau lawm, thiab tso cai rau ntau dua cov khoom ntim.
Polyethylene wax yog dav siv nyob rau hauv cov xim masterbatch ua. Lub hom phiaj ntawm kev ntxiv polyethylene wax tsis yog tsuas yog hloov cov kev ua tau zoo ntawm cov xim masterbatch system, tab sis kuj txhawb cov dispersion ntawm pigments nyob rau hauv cov xim masterbatch. Pigment dispersion tseem ceeb heev rau xim masterbatch. Qhov zoo ntawm Xim Masterbatch feem ntau yog nyob ntawm cov xim dispersion. Zoo pigment dispersion, siab xim lub zog ntawm Xim Masterbatch, xim zoo ntawm cov khoom thiab tus nqi qis. Polyethylene wax tuaj yeem txhim kho qhov tawg ntawm cov xim rau qee yam. Nws yog ib hom dispersant nyob rau hauv zus tau tej cov xim masterbatch.
Vim muaj ntau txoj kev tsim khoom, polyethylene wax tuaj yeem muab faib ua ob hom: hom polymerization thiab hom tawg. Lub qub yog ib yam khoom los ntawm high-pressure polyethylene polymerization, thiab tom kawg yog tsim los ntawm thermal tawg ntawm polyethylene. Vim muaj cov qauv molecular sib txawv, polyethylene wax tuaj yeem muab faib ua ob hom: siab thiab qis ntom ntom, uas zoo ib yam li polyethylene. Vim qhov sib txawv ntawm kev tsim qauv, qhov ntom ntom, qhov hnyav molecular, qhov hnyav molecular faib thiab cov qauv molecular, cov khoom siv ntawm pe ciab hauv xim masterbatch kuj txawv.

Qingdao Sainuope siv quav ciab covmuaj qhov hnyav molecular, siab viscosity, Ob leeg lubrication thiab dispersion; qhov kev ua tau zoo dispersion yog sib npaug rau BASF A wax thiab Honeywell AC6A.
Dispersion mechanism ntawm polyethylene wax pigment nyob rau hauv Xim Masterbatch
Xim masterbatch yog xim xim nrog cob raws li cov cab kuj. Pigment muaj nyob rau hauv peb lub xeev: thawj particle, condensate thiab aggregate. Lub dispersion mechanism ntawm pigment yog tus txheej txheem ntawm rhuav cov polymer hais rau hauv agglomerates thiab thawj hais, thiab stabilizing cov tshiab generated hais. Cov txheej txheem dispersion ntawm cov xim nyob rau hauv resin tuaj yeem qhia nyob rau hauv peb kauj ruam: ua ntej, cov resin yaj moistens cov xim aggregate thiab nkag mus rau hauv lub pores sab hauv; Thib ob, cov aggregates tau tawg nyob rau hauv qhov kev txiav txim ntawm sab nraud shear quab yuam thiab cuam tshuam kev sib tsoo ntawm cov xim pigment; Thaum kawg, cov khoom tsim tshiab yog wetted thiab coated los ntawm resin yaj, uas yog ruaj khov thiab tsis agglomerated.
Cov resin yaj muaj viscosity siab thiab tsis zoo sib xws nrog cov xim nto, yog li nws muaj cov dej tsis zoo thiab nyuaj rau nkag mus rau hauv lub qhov hws ntawm cov khoom sib sau. Yog li ntawd, nws tsis tuaj yeem hloov lub zog shear thiab nws nyuaj rau rhuav tshem cov aggregate. Thaum cov txheej txheem masterbatch nrog polyethylene wax ua tiav, polyethylene wax melts ua ntej cov resin thiab coated rau ntawm cov xim xim. Vim nws tsis tshua muaj viscosity thiab zoo compatibility nrog pigments, polyethylene wax yog ib qho yooj yim rau ntub pigments, nkag mus rau hauv lub puab pores ntawm pigment aggregates, tsis muaj zog cohesion, ua aggregates yooj yim qhib nyob rau hauv qhov kev txiav txim ntawm lwm shear quab yuam, thiab tshiab hais kuj yuav ua tau. sai wetted thiab tiv thaiv. Tsis tas li ntawd, polyethylene wax tuaj yeem txo qhov viscosity ntawm lub cev thiab txhim kho cov dej ntws. Yog li ntawd, ntxiv polyethylene wax nyob rau hauv zus tau tej cov xim masterbatch tuaj yeem txhim kho kev tsim khoom, nce cov zis, thiab tso cai rau cov xim ntau dua.

Qhov sib ntxiv ntawm polyethylene siv quav ciab rau cov xim masterbatch ntxiv dag zog rau cov ntub dej thiab nkag mus ntawm cov pa roj carbon dub aggregates, txo nws qhov loj me los ntawm shear quab yuam, txhim kho kev sib raug zoo ntawm cov kab ke thiab cov pa roj carbon dub, thiab yog qhov zoo rau kev tawg; Nyob rau tib lub sijhawm, txo cov viscosity ntawm lub kaw lus tuaj yeem tsis tsuas yog txhim kho cov txiaj ntsig, tab sis kuj txo qis lub zog shear xa mus rau cov pa roj carbon dub aggregate, uas yog qhov tsis zoo rau kev tawg. Kev sib tw ntawm ob qhov kev sib txawv ua rau muaj qhov ua kom pom tseeb ntawm qhov ntau npaum li cas. Thaum ib qho me me ntawm cov quav ciab ntxiv rau hauv qhov system, nws cov txiaj ntsig zoo dispersion yog ntau dua li qhov cuam tshuam ntawm dispersion, thiab nws qhia tau hais tias muaj kev cuam tshuam zoo dua. Nrog rau kev nce ntawm cov tshuaj siv quav ciab, ob qho kev cuam tshuam tau ntxiv dag zog. Thaum cov wax concentration tshaj ib qho nqi, nws cov teebmeem tsis zoo thiab dispersion yeej. Lub sijhawm no, nws pom tau hais tias cov nyhuv dispersion txo qis.
(1) Txhim kho dispersion thiab xim zog. Vim yog qhov tsim nyog molecular hnyav ntawm polyethylene wax, nws viscosity ua rau cov xim tau qhov zoo tshaj plaws dispersion nyob rau hauv shear quab yuam. Yog li ntawd, nrog tib cov ntsiab lus pigment, muaj qhov sib txawv loj hauv cov xim sib txawv ntawm waxy masterbatch thiab waxless masterbatch.
(2) Txhim kho kev ua tau zoo thiab tawm los. Vim qhov hnyav molecular ntawm polyethylene wax thiab nws cov viscosity qis dua li ntawm cov cab kuj, cov viscosity ntawm tus tswv batch yaj tuaj yeem txo qis.
