PPA Masterbatch

PPA masterbatch (rheological masterbatch, qib masterbatch) yog ib hom kev hloov kho organic fluorine yas ua haujlwm masterbatch.Cov khoom siv LLDPE ua cov khoom thauj khoom (tsis muaj lwm yam kev tsis huv), ntxiv cov tshuaj fluoropolymer siab los muab cov granulation nrog cov txheej txheem tshwj xeeb.PPA masterbatch yog ib qho yooj yim ntxiv, siv tau yooj yim, nrog tus nqi qis heev tuaj yeem txhim kho kev ua haujlwm ntawm polyolefin resin, zoo txo qhov tsis xws luag, txhim kho cov khoom zoo thiab ua kom muaj txiaj ntsig zoo.PPA masterbatch siv hauv mLLDPE, LLDPE, LDPE, HDPE, PP, EVA polyolefin resin, thiab lwm yam.

Khoom siv

Siv dav hauv tshuab tshuab, tshuab, extrusion, extrusion thiab lwm yam khoom siv, xws li zaj duab xis, casting zaj duab xis, yeeb nkab, hlau, phaj, monofilament, fiber ntau thiab lwm yam.

Nco tseg

1. Cov khoom siv ntau lawm yuav tsum tau ntxuav kom huv si ua ntej pib siv.
2. Tom qab pib ua haujlwm, khiav cov khoom siv hauv paus uas muaj 5% PPA masterbatch rau 30 feeb, thiab tom qab ntawd kho nws kom zoo li qub (0.5-2%) rau kev tsim khoom.
3. Yog tias cov cuab yeej tsim khoom ntawm hom masterbatch no txuas ntxiv siv rau lub sijhawm ntev, nws tuaj yeem raug qhib ncaj qha thiab hloov mus rau qhov qub concentration rau ntau lawm.

Cov lus qhia ua haujlwm

1. Ua kom zoo txo qhov tsis xws luag, tshem tawm cov dej ripple (feem ntau hu ua: nab daim tawv nqaij, shark tawv nqaij) tshwm sim los ntawm shear kev nyuaj siab ntawm nruab nrab thiab kev kub ceev PE yaj ntws los ntawm cov hlau nto ntawm cov khoom siv rau ntawm cov yeeb yaj kiab nto thiab wrinkle tsim los ntawm cov yeeb nkab nto.
2. Yog tias tsis hloov cov txheej txheem qub ntawm cov khoom siv, lub peev xwm ntau lawm tuaj yeem ua tau nce los ntawm 5% -10%.Yog tias tsis muaj kev siv lub zog ntawm lub cav tseem ceeb tab sis nce qhov ceev ntawm cov ntsia hlau, lub peev xwm ntau lawm tuaj yeem nce ntxiv mus rau 10% -30%.
3. Ua tau zoo txo qhov tuag lub taub hau kub ntawm 10 ℃ -15 ℃, txhawm rau txhim kho cov yaj ruaj khov ntawm txhua yam kev ua haujlwm siab PE raw cov ntaub ntawv ua tiav los ntawm cov cuab yeej zoo tib yam, xyuas kom ruaj khov thiab txo qhov poob qis.
4. Txhim kho lub plasticizing efficiency ntawm extruder ntsia hlau, thiaj li los txhim kho lub pob tshab, nto brightness thiab smoothness ntawm cov khoom, los xyuas kom meej lub thickness uniformity thiab thickness stability ntawm cov khoom, los xyuas kom meej cov khoom zoo.
5. Ua kom txo tau cov ntsiab lus siv lead ua uas ua rau hauv cov txheej txheem ntawm tshuab zaj duab xis lossis extrusion ua, thiaj li txo cov ntsiab lus dawb los ntawm cov ntsiab lus siv lead ua ntawm cov khoom nto.
6. Txo lossis tshem tawm lub taub hau tuag precipitates, tshem tawm cov kab ntev ntev uas tshwm sim los ntawm kev sib sau ntawm lub taub hau tuag lossis cov khoom siv sib kis ntawm cov khoom siv.
7. Nws tuaj yeem ua rau cov metallocene linear low density polyethylene mLLDPE zaj duab xis txhim kho kev ua tau zoo thiab muaj kev sib khi nrawm, ua kom muaj kev ntseeg siab ntawm kev sib khi kab nrawm, thiab ua kom muaj kev sib ntxiv ntawm metallocene linear low density polyethylene mLLDPE raws li kev tswj lub cev thiab tshuaj, ua npuas dej ruaj khov. txhim kho.
