Izidingo zenqubo yokukhiqiza ye-masterbatch yombala ziqinile kakhulu, futhi inqubo emanzi ivame ukusetshenziswa.I-masterbatch yombala iphansi futhi iguqulwa ngesigaba ngamanzi, futhi uchungechunge lokuhlola kufanele lwenziwe ngenkathi i-pigment isacolwa, njengokunqunywa kokucoleka, ukusebenza kokusabalalisa, okuqukethwe okuqinile kanye nokunamathisela kombala ukucoleka kwe-sanding slurry.
Kunezinqubo ezine zokukhiqiza ezimanzi ze-masterbatch yombala: indlela yokuwasha, indlela yokuxova, indlela yensipho yensimbi, nendlela kayinki.
(1) Indlela yokugeza: I-pigment, amanzi kanye ne-dispersant kufakwe isihlabathi ukwenza izinhlayiya ze-pigment zibe zincane kune-1pm, futhi i-pigment idluliselwe esigabeni samafutha ngendlela yokudlulisa isigaba, bese yomiswa ukuze kutholwe i-masterbatch yombala.Izinyibilikisi ze-Organic kanye namadivayisi ahambisanayo okubuyisela i-solvent ayadingeka ekuguquleni kwesigaba.Inqubo imi kanje:
I-pigment, i-disperant, inani elisizayo - i-ball mill - i-homogenization kanye nokwelashwa kokuzinzisa - ukomisa - ukuxuba i-resin - i-extrusion granulation colorbatch masterbatch
(2) Indlela yokuxova Ukugeleza kwenqubo yendlela yokuxova imi kanje:
I-pigment, izinsiza, ukuxova inhlaka - ukuphela kwamanzi - ukomisa - ukuxuba i-resin - i-extrusion granulation ibe yi-masterbatch
(3) Indlela yombala wensipho yensimbi igaywe ibe usayizi oyizinhlayiyana ezingaba yi-1um, bese isixazululo sensipho sengezwa ezingeni lokushisa elithile ukuze kwenziwe ungqimba olungaphezulu lwezinhlayiya ze-pigment zimanziswe ngokulinganayo yisisombululo sensipho ukuze kwakhe ungqimba lwesisombululo se-saponification. .Engeza isisombululo sikasawoti wensimbi kanye nobuso be-pigment.Isendlalelo se-saponification sisabela ngokwamakhemikhali ukuze sakhe isendlalelo esivikelayo sensipho yensimbi (i-magnesium stearate), ukuze izinhlayiya ze-pigment ezigaywe kahle zinganyakazi.
Ukugeleza kwenqubo yendlela yensipho yensimbi imi kanje:
I-pigment, izinsiza, ukuxuba amanzi - ukuhlukaniswa kanye nokuphelelwa amandla kwamanzi - ukomisa - ukuxuba i-resin - i-extrusion granulation ibe yi-masterbatch
(4) Indlela kayinki Ekukhiqizeni i-masterbatch yombala, kusetshenziswa indlela yokukhiqiza yokunamathisela umbala kayinki, okungukuthi, ngokugaya ngama-roll-roll, ungqimba oluncane lokuvikela lwamangqamuzana lumbozwa phezu kombala.Unamathisele ocolile ogayiwe uxutshwa ne-resin ye-carrier, bese wenziwa ipulasitiki ngesigayo se-twin-roll, futhi ekugcineni ucwecwe ngesikulufu esisodwa noma i-twin-screw extruder.
Ukugeleza kwenqubo kungokulandelayo:
Ama-pigment, izithasiselo, ama-disperants, ama-resin, izithako ze-solvent - unamathisele wombala we-mill-roll-roll - desolventizing - ukuxuba kwe-resin - i-extrusion granulation ibe yi-masterbatch.
Inqubo yokugeleza kokukhiqizwa okomile kwe-masterbatch yombala: i-pigment (noma udayi) insiza, i-disperant, umthwali - ukuxuba ngesivinini esikhulu, ukugqugquzela nokugunda - i-twin-screw extrusion granulation - ukusika okubandayo kanye ne-granulation ku-masterbatch yombala
