Raws li qib siab - cov khoom siv xim xim, qhov chaw cia ntawm cov xim masterbatch ncaj qha cuam tshuam rau nws cov xim ruaj khov, kev ua haujlwm tawg, thiab kev ua haujlwm tom qab. Vim nws muaj pigments, carrier resins, thiab ntau yam additives, xim masterbatch yog rhiab heev rau lwm yam ib puag ncig. Kev khaws cia tsis raug tuaj yeem ua rau muaj teeb meem xws li clumping, fading, thiab kev ua haujlwm tsis zoo. Tsim kom muaj kev tshawb fawb thiab kev tswj xyuas cov txheej txheem yog lub hauv paus rau kev ua kom cov khoom zoo thiab kev ua haujlwm ntau lawm.
Qhov chaw cia khoom yuav tsum ua qhov tseem ceeb kom qhuav, txias, thiab tiv thaiv lub teeb. Lub hygroscopicity ntawm cov xim masterbatch txawv nyob ntawm seb hom cab kuj thiab xim. Cov av noo ntau dhau tuaj yeem ua rau cov khoom nqus dej noo thiab clump, cuam tshuam rau kev ntws thiab ntsuas qhov tseeb hauv cov cuab yeej ua haujlwm, thiab hauv cov xwm txheej hnyav, ua rau tsis sib xws lossis xim sib txawv. Yog li ntawd, qhov txheeb ze av noo ntawm lub tsev khaws khoom yuav tsum tswj tau qis dua 50%, thiab nws yuav tsum tsis txhob nyob ib sab ntawm cov dej los yog qhov chaw siab - av noo. Hais txog qhov kub thiab txias, nws raug nquahu kom tswj nws nyob rau hauv qhov ntsuas kub ib txwm (feem ntau 15℃~ 30 degree), kom deb ntawm qhov chaw sov thiab tshav ntuj ncaj qha los tiv thaiv softening thiab deformation ntawm cov cab kuj los yog thermal degradation thiab xim drift ntawm cov xim.
Cov thawv ntim khoom thiab ntim khoom yuav tsum tau muab kaw kom ruaj thiab ruaj khov. Cov khoom lag luam uas muaj cov khoom lag luam feem ntau yog ntim rau hauv cov dej noo- cov ntaub ntawv pov thawj sab hauv thiab cov ntawv- cov hnab yas sib xyaw lossis cov dej noo- cov hnab pov thawj pov thawj, tiv thaiv kom tsis txhob ya raws thiab cov kab mob nkag mus thaum lub sijhawm thauj mus los thiab luv luv - lub sijhawm cia. Rau lub sijhawm ntev - khaws cia, ib qho dej tsis qab thiab lub teeb- cov ntaub ntawv pov thawj sab nrauv yuav tsum muab ntxiv rau cov ntim khoom qub, lossis cov khoom yuav tsum muab tso rau hauv lub thawv ntim khoom ntim. Yog tias tsim nyog, cov roj inert yuav tsum tau ntxiv los yog cov khoom siv desiccants kom txo qis kev pheej hmoo ntawm kev nqus dej. Masterbatches ntawm cov xim sib txawv lossis cov qauv yuav tsum tau muab cais thiab sau kom meej meej kom tsis txhob muaj kev ntxhov siab thiab hla kev sib kis.
Nyob rau hauv cov nqe lus ntawm kev tswj stacking, thawj -in, thawj- tawm (FIFO) txoj cai yuav tsum tau ua raws li los tiv thaiv kev ua tau zoo degradation vim kev cia ntev. Lub stacking qhov siab yuav tsum tau txiav txim siab raws li lub zog ntim kom tsis txhob muaj qhov tawg lossis ntim puas vim qhov hnyav hnyav. Lub tsev khaws khoom yuav tsum tau tshuaj xyuas tsis tu ncua los xyuas qhov tseeb ntawm lub ntim, cov ntaub ntawv kub thiab av noo, thiab rau tej yam txawv txav xws li tsw ntxhiab lossis tsis muaj xim. Yog tias pom muaj dej noo, clumping, lossis xav tias muaj kev puas tsuaj, cov khoom yuav tsum tau muab cais tawm tam sim ntawd thiab ntsuas kev siv txuas ntxiv; nws yuav tsum tsis txhob siv nyob rau hauv ntau lawm yam tsis tau tso cai.
Tsis tas li ntawd, cov xim masterbatches yuav tsum tau khaws cia kom deb ntawm cov oxidants muaj zog, acidic lossis alkaline chemicals, thiab cov kuab tshuaj organic los tiv thaiv cov tshuaj tiv thaiv uas tuaj yeem ua rau cov xim xim puas. Ua tib zoo saib xyuas thaum thauj mus los tiv thaiv kev ua phem phem uas tuaj yeem ua rau muaj plua plav lossis tawg, yog li txo cov kev phom sij ntawm kev ua haujlwm.
Hauv cov ntsiab lus, kev cia thiab tswj cov xim masterbatches yog ib qho kev ua haujlwm uas muaj feem xyuam nrog kev tswj hwm ib puag ncig, kev tiv thaiv kev ntim khoom, kev faib tawm thiab kev sau npe, thiab kev tshuaj xyuas ib ntus. Tsuas yog ua raws li cov qauv ntsuas kub, av noo, airtightness, thiab kev nyab xeeb ntawm kev ua haujlwm tuaj yeem khaws lawv cov kev ua haujlwm qub, ua kom cov xim sib xws thiab cov khoom ruaj khov hauv kev ua haujlwm tom ntej.
