Pre-dispersed Pigment thiab Tib Pigment Concentration

Nrog rau kev txhim kho tas mus li ntawm kev lag luam, niaj hnub no cov yas colouring ua thiab molding yog txav mus rau tiam sis ntawm cov khoom siv loj, cov khoom siv hluav taws xob ntau, kev ua haujlwm siab, kev ua haujlwm tsis tu ncua thiab kev tsim khoom ntawm cov khoom.Cov qauv no tau ua rau ntau cov khoom siv ultra-nplua, ultra-nyias thiab ultra-micro cov khoom, uas yuav tsum tau ntau dua cov qauv ntawm cov xim dispersion.Tsis tas li ntawd, qhov kev xav tau ntawm kev ua haujlwm siab, kev tiv thaiv ib puag ncig, kev txuag hluav taws xob thiab kev txo nqi kuj nce ntxiv.Vim tias cov khoom siv yas molding dav dav (xws li: kev txhaj tshuaj molding tshuab, spinning tshuab lossis ib qho ntsia hlau extruder, thiab lwm yam) tsis tuaj yeem muab lub zog shear quab yuam uas yuav tsum tau ua rau cov xim dispersion thaum ua, cov xim dispersion ua hauj lwm feem ntau yog ua los ntawm cov kws manufacturers-pigment lwm tus neeg. los yog xim masterbatch manufacturers.

Pre-dispersed pigment(tseem hu ua Pigment Preparation los yog SPC-Single Pigment Concentration) yog ib qho siab ntawm ib qho xim.Raws li cov yam ntxwv ntawm cov xim sib txawv, cov xim ua ntej dispersed muaj 40-60% ntawm cov xim xim (cov ntsiab lus zoo ntawm cov xim ua ntej dispersed ua los ntawm peb lub tuam txhab tuaj yeem ncav cuag 80-90%), thiab ua tiav los ntawm ib qho tshwj xeeb. txheej txheem los ntawm cov cuab yeej tshwj xeeb.Cov txheej txheem dispersion zoo thiab kev tswj xyuas nruj ua rau cov pigments muaj qhia cov ntawv zoo tshaj plaws kom ua tiav cov xim zoo tshaj plaws.Cov tsos ntawm cov xim ua ntej dispersed tuaj yeem ua tau zoo particles nrog qhov loj ntawm 0. 2-0.3mm, thiab cov khoom tuaj yeem ua rau particle nrog qhov loj ntawm ntau yam.xim masterbatch.Nws yog precisely vim hais tias cov pre-dispersed pigment muaj xws li pom tseeb yam ntxwv uas yog nce siv nyob rau hauv kev tsim cov xim masterbatches.

• Txij li thaum cov pigment yog dispersed tag, nws muaj zog xim.Piv nrog rau kev siv cov hmoov pigments, cov xim muaj zog feem ntau tuaj yeem txhim kho los ntawm 5-15%.

• Cov txheej txheem homogeneous yuav tsum tau tsuas yog me me shear sib xyaw rog kom ua tiav cov txiaj ntsig xav tau.Piv txwv li, cov khoom lag luam zoo xim masterbatch tuaj yeem ua nrog cov khoom siv yooj yim (xws li ib lub hau ntswj).Kho kom haum rau txhua yam khoom siv extrusion, ruaj khov zoo, hloov tau yooj yim ntau lawm.

• Pre-dispersed pigment ua haujlwm kom ua tiav cov xim zoo nkauj: xim ci, pob tshab, gloss, thiab lwm yam.

• Tshem tawm cov plua plav ya hauv cov txheej txheem tsim khoom, txhim kho qhov chaw ua haujlwm thiab txo cov pa phem.

• Tsis muaj cov cuab yeej fouling, ua kom yooj yim tu cov cuab yeej thaum hloov xim.

• Cov xim zoo nkauj thiab cov xim tsis sib xws tuaj yeem ua rau lub neej ntev ntawm cov ntxaij lim dej, txo lub sijhawm hloov ntawm cov ntxaij lim dej thiab txhim kho kev tsim khoom.

• Cov tsos ntawm cov khoom yog ib yam tsis muaj kev sib nrig sib stickiness, uas yog haum rau ntau yam feeder qauv;cov txheej txheem conveying tsis txuas los yog thaiv.

• Tshem tawm qhov yuav tsum tau disperse pigments thiab ua rau kom muaj peev xwm ntawm masterbatch ntau lawm chaw.

• Yuav siv tau nrog lwm cov xim, nrog rau kev siv zog.

• Ntau cov ntawv ntau npaum li cas, haum rau cov ntaub ntawv sib txawv ntawm cov cab kuj, kev sib xyaw ua haujlwm zoo.
