Koj puas paub qhov txawv ntawmpolyethylene waxthiab paraffin ciab nyob rau hauv masterbatch ua?Yog tias koj yog cov chaw tsim khoom ntawm xim masterbatch lossis ib tus phooj ywg uas nyiam xim masterbatch, ces ua raws li cov kauj ruam ntawmSainuo.Hnub no tsab xov xwm yeej muaj txiaj ntsig rau kojntau.

Cov xim masterbatch yog xim xim xim nrog cov resin ua tus nqa khoom.Cov resin muaj siab yaj viscosity thiab tsis zoo compatibility nrog rau saum npoo ntawm cov xim, yog li lub wetting yog tsis zoo, thiab nws yog ib qho nyuaj rau nkag mus rau hauv lub pores ntawm lub agglomerate kom tawg lub agglomerate;uas yog, nyob rau hauv lub agglomerate Tom qab tau tawg lawm, cov resin yaj tsis tuaj yeem ntub dej sai sai thiab tiv thaiv lub nascent nto, thiab kev sib tsoo thiab kev sib cuag yuav ua rau cov khoom sib sau ua ke.Qhov teeb meem no tuaj yeem daws tau los ntawm kev ntxiv polyethylene wax.

Nyob rau hauv lub teb ntawm masterbatch ntau lawm, qhov sib ntxiv ntawm paraffin wax thiab polyethylene wax tuaj yeem txhim kho cov dej ntws ntawm cov ntaub ntawv, txhim kho cov ntub dej thiab dispersibility ntawm cov xim thiab lwm yam additives, thiab tom qab ntawd txhim kho kev ua haujlwm thiab kev tsim khoom kom sib txawv.Cov xim dispersion yog qhov zoo, lub zog xim ntawm cov masterbatch yog siab, cov xim zoo nkauj ntawm cov khoom yog qhov zoo, thiab cov khoom xim yog tsawg.

Yog li ntawd, ntau manufacturers siv paraffin wax nrog ib tug melting point ntawm txog 60 ° C raws li ib tug dispersant los yog siv ua ke nrog polyethylene wax kom ntau lawm thiab txo nqi.Tam sim no cia saib qhov kev ua tau zoo sib txawv ntawm ob los ntawm qhov kev xav ntawm kev siv tswv yim ntawm kev ua tiav masterbatch.

1. Lub cev thiab tshuaj muaj zog
Paraffin wax: English npe Paraffin Wax, dawb khoom, ntom 0.87-0.92g / cm3, melting point 55-65 ℃
Polyethylene Wax: English npe Polyethylene Wax, dawb khoom, ntom 0.91-0.95g / cm3, melting point 90-115 ℃

2.Thermal stability
Lub lubricating thiab dispersing tus neeg sawv cev siv rau lub masterbatch yuav tsum muaj peev xwm tiv taus qhov kub thiab txias thaum lub sij hawm tsim cov masterbatch thiab molding ntawm cov khoom xim.Yog tias nws vaporizes lossis decomposes, nws yuav muaj kev cuam tshuam tsis zoo rau cov masterbatch lossis cov khoom xim.
Kev ua haujlwm kub ntawm masterbatch thiab cov khoom yog feem ntau ntawm 160-220 ℃.Nyob rau hauv qhov kub thiab txias, feem ntau polyethylene wax tuaj yeem tiv taus, tab sis paraffin siv quav ciab nyuaj rau tiv taus.Peb tau ua cov kev sim poob phaus isothermal ntawm polyethylene wax thiab paraffin wax nrog lub melting point ntawm 60 ° C, thiab pom tias, qis dua 200 ° C, paraffin poob 9.57% ntawm nws qhov hnyav hauv 4 feeb, thiab hauv 10 feeb, qhov hnyav poob. mus txog 20%.Tsuas yog los ntawm qhov pom ntawm kev ua kom sov, polyethylene siv quav ciab tuaj yeem pom cov cua sov zoo, thaum paraffin wax nyuaj rau lav, yog li paraffin siv quav ciab tsis haum rau kev siv xim masterbatch dispersant.

3.Dispersion kev ua tau zoo
Txhawm rau sib piv thiab ntsuas cov khoom tawg ntawm polyethylene wax thiab paraffin wax, dub masterbatches tau npaj nrog qhov sib txawv ntawm qhov sib txawv ntawm ob, raws li, thiab kev kuaj dub ntawm zaj duab xis tau ua tiav.
Cov txiaj ntsig kev sim pom tau hais tias nyob rau hauv qhov sib ntxiv ntawm 0-7%, nrog rau kev nce ntawm polyethylene wax cov ntsiab lus ntawm cov masterbatch dub, cov yeeb yaj kiab blackness nce tsis tu ncua los ntawm 36.7%, qhia tias ntau dua cov ntsiab lus ntawm polyethylene wax, qhov zoo dua qhov kev ua tau zoo ntawm kev ua haujlwm carbon dub.Txawm li cas los xij, nyob rau hauv tib qhov sib ntxiv, nrog rau qhov nce ntawm paraffin, qhov dub ntawm cov masterbatch dub tau txo qis los ntawm 19.9%, qhia tias qhov siab dua cov ntsiab lus paraffin, qhov ua haujlwm tsis zoo ntawm cov pa roj carbon dub.
Qhov no yog vim hais tias paraffin waxes ntub cov pa roj carbon dub yooj yim dua li polyethylene waxes, tab sis tib lub sij hawm txo cov viscosity ntawm lub system.Tsawg viscosity tsawg heev ua rau kev sib kis ntawm shear quab yuam, thiab dispersion cuam tshuam.Lub luag haujlwm ntawm agglomeration cohesion.Yog li ntawd, qhov 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 loj heev.

Qingdao Sainuo Chemical Co., Ltd.Peb yog cov chaw tsim khoom rau PE ciab, PP ciab, OPE ciab, EVA ciab, PEMA, EBS, Zinc / Calcium Stearate ....Peb cov khoom tau dhau REACH, ROHS, PAHS, FDA kuaj.

Sainuo so assured ciab, txais tos koj nug!
