Umbala we-masterbatch (ekwaziwa ngokuba yi-color masterbatch) yi-aggregate efunyenwe ngokulayisha ngokufanayo ii-pigments ezizii-super-constant okanye iidayi kwiireyini.Iqulunqwe ngamacandelo amathathu: ii-pigments (okanye iidayi), abathwali kunye nee-agent agents.igxininise, ngoko amandla ayo okuthambisa angaphezulu kwebala ngokwalo.
Masterbatch izithako ezisisiseko:
1. I-Toner: Ii-pigments eziphezulu (okanye iidayi) zingasetyenziselwa ukwenza i-masterbatches yombala okhethekileyo okanye i-masterbatches yombala wenjongo ngokubanzi kwiiplastiki ezahlukeneyo;Kwakhona kunokwenzeka ukuba uqale ulungiselele imibala efanelekayo kwaye emva koko udibanise i-pigments kunye nombala we-masterbatch carrier ngokomlinganiselo wefomula.Ngokufudumeza, ukwenza iplastiki, ukuvuselela kunye nokucheba isenzo segranulator, iimolekyuli ze-pigment kunye neemolekyuli ze-carrier resin ekugqibeleni zidityaniswe ngokupheleleyo ukwenza amasuntswana afana nobukhulu kumasuntswana eresin, oko kukuthi, umbala we-masterbatch.
Imibala yendalo esetyenziswa ngokuqhelekileyo zezi: i-koji ebomvu cyanine blue cyanine eluhlaza lightfast ebomvu macromolecular ebomvu, macromolecular etyheli esisigxina, imfusa esisigxina, i-azo ebomvu kunye nezinye i-pigments ezisetyenziswa ngokuqhelekileyo yimbiza ebomvu etyheli, i-titanium dioxide, i-carbon Iron oxide ebomvu, i-iron oxide etyheli, njl.
2. Umthwali: Umbala okhethekileyo we-masterbatch carrier sisiseko sombala we-masterbatch.Ngokuqhelekileyo, i-resin efanayo kunye ne-resin yemveliso ikhethwa njengomthwali, ukwenzela ukuba ukuhambelana kwezi zibini kuyona nto ibhetele, kodwa umbane we-carrier kufuneka uphinde uqwalaselwe.
3. Abancedisi: ikakhulu babandakanya ii-dispersants, i-coupling agents, ii-compatibilizers, njl. njl.Indawo yokunyibilika ye-dispersant kufuneka ibe ngaphantsi kwe-resin, kwaye inokuhambelana kakuhle kunye ne-resin kunye nobudlelwane obuhle be-pigment.Ezona zinto zixhaphakileyo zisetyenziswa ngokusasaza i-polyethylene i-wax ephantsi yobunzima bemolekyuli kunye ne-stearates.
Ezinye izongezo, ezifana ne-flame retardants, i-lighteners, i-antibacterial agents, i-antistatic agents, i-antioxidants, njl., inokongezwa kwi-masterbatch yombala.Ngaphandle kokuba umthengi ucela, i-masterbatch yombala ayinazo ezongezo zingentla.
