Basic Knowledge Of Yas Fwj Technology
Xim txuam thiab xim txheej txheem
Rau cov xim sib txuam thiab xim, toner tuaj yeem ncaj qha ntxiv rau cov khoom siv, toner tov nrog resin extrusion thiab masterbatch txoj kev.
Toner ncaj qha ntxiv rau txoj kev cob qhia:
Tom qab lub toner yog ncaj qha tov nrog cov yas resin, nws raug xa mus rau cov kauj ruam tom ntej ntawm cov khoom molding txheej txheem. Cov txheej txheem luv luv thiab tus nqi qis, tab sis qhov chaw ua haujlwm tsis zoo, lub zog xim tsis zoo, cov xim sib xws thiab kev ruaj ntseg zoo tsis zoo.
Toner mix resin extrusion txoj kev:
Txoj kev no muaj kev cuam tshuam zoo dua rau qhov sib xws ntawm cov resin thiab xim, thiab tuaj yeem tawg tag nrho cov xim hauv cov resin, nrog cov xim raug, huv si thiab ua haujlwm yooj yim.
Masterbatch txoj kev:
Colorant, carrier resin, dispersant, thiab lwm yam additives yog formulated rau hauv pellets nrog ib tug tej yam concentration ntawm colorant. Thaum cov khoom tsim, ib qho nyiaj ntawm cov xim masterbatch yog ntxiv raws li cov xim uas yuav tsum tau ua, kom cov khoom muaj cov xim uas yuav tsum tau muaj thiab ua tau raws li cov xim uas yuav tsum tau ua.
Xim masterbatch tuaj yeem raug cais raws li cov xim pleev xim, xws li ABS masterbatch, PC masterbatch, PP masterbatch, thiab lwm yam. Nws tseem tuaj yeem raug cais raws li cov xim pleev xim ua cov tshuab, muaj peb hom masterbatches: txhaj tshuaj molding, tshuab zaj duab xis, qib extrusion. Vim lub pretreatment ntawm cov pigments, cov xim masterbatch muaj siab tinting zog, qhov ntau npaum yuav txo tau thiab qhov zoo yog ruaj khov, kev thauj mus los, cia thiab siv tau yooj yim, thiab ib puag ncig muaj kuab heev txo.
Lub dispersant tshem tawm cov huab cua saum npoo los ntawm ntub dej thiab nkag mus rau cov xim, disperses cov aggregates thiab aggregates rau hauv cov khoom zoo, ruaj khov thiab zoo ib yam, thiab tsis sib sau ua ke thaum lub sij hawm ua. Feem ntau siv dispersant yog tsis tshua muaj molecular hnyav polyethylene wax. Rau cov organic pigments thiab carbon dub uas nyuaj rau disperse, EVA wax los yog oxidized polyethylene wax yog siv. Muaj qhov sib txawv loj ntawm cov khoom siv hluavtaws uas tsis muaj molecular hnyav polyethylene wax thiab tsis tshua muaj molecular hnyav polyethylene wax ua los ntawm polyethylene tawg. Lwm cov additives muaj xws li coupling agents, antioxidants, lub teeb stabilizers, antistatic agents, fillers, thiab lwm yam. Cov nyiaj ntxiv yog nyob ntawm qhov yuav tsum tau thiab ntau yam. Lawv hu ua multifunctional masterbatches. Ntxiv cov brighteners yog qhov zoo rau cov khoom molding. Tso cov pwm thiab txhim kho qhov ci ntsa iab ntawm cov khoom.
Cov kev ua tau zoo ntawm masterbatches muaj xws li xim txawv, whiteness, yellowing, yellowing degree, thermal stability, oxygen index, yaj txaus tus nqi, thiab lwm yam. Qee qhov taw qhia tseem ceeb heev hauv cov hom phiaj tshwj xeeb, xws li qhov zoo ntawm cov ntawv lim xovxwm (DF tus nqi) ntawm fiber ntau masterbatches.
