Iimfuno zenkqubo yokuvelisa i-masterbatch yombala zingqongqo kakhulu, kwaye inkqubo emanzi isetyenziswa ngokubanzi.I-masterbatch yombala iphantsi kwaye i-phase-inverted ngamanzi, kwaye uchungechunge lweemvavanyo kufuneka luqhutywe ngelixa i-pigment isenziwa phantsi, njengokumisela ukucoleka, ukusebenza kwe-diffusion, umxholo oqinileyo kunye nombala wokuncamathisela ukucoleka kwe-sanding slurry.
Kukho iinkqubo ezine zokuvelisa ezimanzi ze-masterbatch yombala: indlela yokuhlamba, indlela yokuxova, indlela yesepha yesinyithi, kunye nendlela ye-inki.
(1) Indlela yokuhlamba: I-pigment, amanzi kunye ne-dispersant is sanded ukwenza i-pigment particle ibe yincinci kune-1pm, kwaye i-pigment idluliselwe kwisigaba seoli ngendlela yokudluliselwa kwesigaba, kwaye yomiswa ukuze ifumane i-masterbatch yombala.I-solvents ye-Organic kunye nezixhobo ezihambelanayo zokubuyisela i-solvent ziyafuneka kwi-inversion yesigaba.Inkqubo imi ngolu hlobo lulandelayo:
I-pigment, i-disperant, isixa esincedisayo - i-ball Mill - i-homogenization kunye nonyango lokuzinzisa - ukomisa - ukuxuba i-resin - i-extrusion granulation colorbatch
(2) Indlela yokuxova Inkqubo yokuhamba kwendlela yokuxova imi ngolu hlobo lulandelayo:
I-pigment, izinto ezincedisayo, ukuxova i-resin - ukuphelelwa ngamanzi emzimbeni - ukomisa - ukuxuba i-resin - i-extrusion granulation kwi-masterbatch
3 .Yongeza isisombululo setyuwa yensimbi kunye nomphezulu we-pigment.Umaleko we-saponification ngokwekhemikhali usabela ukwenza umaleko okhuselayo wesepha yesinyithi (i-magnesium stearate), ukuze amasuntswana ebala elicolekileyo angashukumi.
Ukuhamba kwenkqubo yendlela yesepha yentsimbi imi ngolu hlobo lulandelayo:
I-pigment, izinto ezincedisayo, ukuxuba amanzi - ukwahlukana kunye nokuphelelwa ngamanzi emzimbeni - ukomisa - ukuxuba i-resin - i-extrusion granulation kwi-masterbatch
(4) Indlela ye-Ink Ekuveliseni i-masterbatch yombala, indlela yokuvelisa i-inki yokuncamathisela yombala isetyenzisiweyo, oko kukuthi, ngokusila nge-three-roll, umaleko ophantsi okhuselayo wemolekyuli ugqunywe kumphezulu we-pigment.Intlama ecolekileyo egayiweyo ixutywe ne-resin ye-carrier, emva koko ifakwe iplastiki nge-twin-roll mill, kwaye ekugqibeleni ihlanjululwe nge-screw-screw okanye i-twin-screw extruder.
Inkqubo yokuhamba ngolu hlobo lulandelayo:
Ii-pigments, i-additives, i-dispersants, i-resin, izithako ze-solvent-i-three-roll mill color paste - i-desolventizing - ukuxuba i-resin - i-extrusion granulation kwi-masterbatch.
Inkqubo yokuhamba kwemveliso eyomileyo ye-masterbatch yombala: i-pigment (okanye idayi) encedisayo, i-dispersant, i-carrier - ukuxuba ngesantya esiphezulu, ukuvuselela kunye nokucheba - i-twin-screw extrusion granulation - ukusika okubandayo kunye ne-granulation kwi-masterbatch yombala.
