Raws li ib qho tseem ceeb nruab nrab ntawm cov xim ntawm cov ntaub ntawv polymer, tus qauv kev tswj hwm ntawm daim ntawv thov masterbatch ncaj qha cuam tshuam cov xim sib xws, ntsuas kev ua tau zoo, thiab kev tsim khoom ntawm cov khoom tiav. Txij li thaum masterbatch ua ke nrog cov matrix resin nyob rau hauv melt blending los yog premixing txheej txheem, daim ntawv thov txheej txheem yuav tsum ua raws li kev tshawb fawb parameter tswj thiab kev ua hauj lwm specifications kom txo tau cov xim sib txawv, dispersion defects, thiab tej zaum yuav zoo txaus ntshai.
Qhov kev npaj ua ntej yuav tsum tsim kom muaj cov txheej txheem tseeb. Raws li hom matrix resin, tus qauv masterbatch, thiab cov yam ntxwv ntawm cov khoom siv, cov ntaub ntawv ua tiav yuav tsum tau tsim, suav nrog kev sib xyaw ua ke, kev ua haujlwm kub, ntsia hlau ceev, rov qab siab, thiab kev noj qab haus huv. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb kom paub tseeb tias lawv paub txog cov txheej txheem thiab cov ntsiab lus tseem ceeb. Masterbatch thiab matrix hais yuav tsum tau muab cia rau hauv qhov chaw qhuav, huv si kom tsis txhob cuam tshuam rau kev tawg vim yog nqus dej los yog muaj kab mob.
Metering thiab pub mis yuav tsum nruj me ntsis ua raws li cov ntsiab lus ntau. Nws raug nquahu kom siv cov khoom hnyav nrog qhov raug tsawg kawg yog ± 0.5% kom raug ntxiv cov xim masterbatch raws li qhov kev txiav txim siab ua ntej, tsis txhob muaj xim sib txawv los yog qhov txawv txav vim muaj ntau dua - lossis qis dua - ntxiv. Hauv ntau -cov khoom sib xyaw ua ke, lub hauv paus ntsiab lus ntawm kev pub mis matrix ua ntej thiab tom qab ntawd cov xim masterbatch, lossis pub rau lawv ib txhij, yuav tsum ua raws. Xyuas kom meej tias txoj hauj lwm pub mis tso cai rau cov xim masterbatch kom yaj thiab tawg mus rau hauv qhov siab - kub, siab -shear cheeb tsam, tiv thaiv cov khoom tsis sib haum los ntawm kev tsim cov xim xim.
Kev teeb tsa qhov kub thiab txias yuav tsum coj mus rau hauv tus account lub thermal zog ntawm ob qho tib si cov cab kuj thiab cov matrix resin. Tsis tshua muaj kub yuav ua rau tsis tiav dispersion ntawm cov xim masterbatch, thaum kub heev yuav ua rau pigment decomposition los yog carrier carbonization, cuam tshuam cov xim thiab txhua yam khoom ntawm cov khoom. Qhov ntsuas kub tsim nyog yuav tsum tau teeb tsa hauv cov khoom siv tau tso cai, thiab kev hloov kho yuav tsum tau ua tam sim los ntawm kev saib xyuas cov xim yaj hauv online. Qhov sib txuam ntawm cov ntsia hlau ceev thiab kev siv lub zog kuj yuav tsum tau ua kom zoo dua kom ntseeg tau tias muaj kev sib cais tsis sib xws thaum tsis txhob muaj cov shearing ntau dhau uas tuaj yeem ua rau cov khoom degradation.
Tag nrho - kev soj ntsuam zoo yuav tsum tau ua thaum lub sij hawm tsim kho. Tsis tu ncua coj mus kuaj thiab tshuaj xyuas cov khoom rau qhov sib txawv xim, qhov chaw tsis xws luag, thiab lub cev muaj zog. Yog tias pom muaj qhov txawv txav, tam sim ntawd nres lub tshuab tshawb xyuas qhov ua rau thiab kho qhov tsis zoo. Lub xaib yuav tsum tau ua kom huv si kom tsis txhob muaj cov khoom txawv teb chaws nkag mus. Cov masterbatch uas tseem tshuav yuav tsum tau muab kaw thiab khaws cia kom tsis txhob ya raws los yog kis kab mob. Tom qab kev tsim kho, cov ntaub ntawv tseem ceeb ntawm cov txheej txheem yuav tsum tau sau tseg thiab khaws cia los muab lub hauv paus rau kev ua raws li cov khoom siv tom ntej thiab kev txhim kho txuas ntxiv.
Hauv cov ntsiab lus, cov qauv tsim qauv masterbatch npog cov txheej txheem tsim, ntsuas thiab pub mis, tswj kev ntsuas, thiab kev tshuaj xyuas zoo. Tsuas yog los ntawm kev ua kom zoo thiab kev ua kom zoo dua qub tuaj yeem ua kom ruaj khov thiab cov xim zoo ib yam tuaj yeem ua tiav nyob rau hauv loj - nplai ntau lawm, yog li txhim kho tag nrho cov qib tsim khoom thiab cov khoom sib tw.
