Yuav ua li cas koj xam tus nqi npaum li cas rau xim masterbatch hauv extrusion?

Xam cov xim masterbatch ntau npaum li cas pib nrog lub hom phiaj xim lub zog thiab pigment loading hauv masterbatch. Cov neeg muag khoom feem ntau cov npe cia -tus piv- feem ntau yog 1–4% (20: 1 txog 50: 1). Rau 100 kg / hr extruder khiav ntawm 2% noj, pub 2 kg / hr ntawm masterbatch. Ntsuas lub hauv paus resin tso zis thiab faib los ntawm cia-tus piv kom tau tus nqi masterbatch. Gravimetric dosers tuav qhov no txiav los ntawm kev ntsuas qhov hnyav. Rau volumetric dosers, calibrate ntsia hlau ceev tiv thaiv qhov tseeb throughput-khiav sij hawm mus kuaj thiab kho. (xim masterbatch) nrog 40-60% pigment xav tau qis feem pua ​​​​ntawm 20-30% hom. Test xim chips los ntawm qhov tuag- lub teeb dhau txhais tau tias nce noj, tsaus dhau txhais tau tias txo. Tus account rau regrind- cov ntsiab lus regrind siab dua yuav xav tau masterbatch ntxiv los them rau cov xim faded. Khaws cov ntaub ntawv ntawm kev teeb tsa ib txoj haujlwm kom ua haujlwm rov qab tau yooj yim. Kev suav kom raug zam kom tsis txhob pov tseg, dhau - xim, lossis qhov tsis muaj zog los ntawm cov khoom thauj ntau dhau.
