Izvo zvinodiwa zvekugadzira zvemavara masterbatch zvakanyanya kuomarara, uye iyo yekunyorova maitiro inowanzo shandiswa.Iyo colorbatch masterbatch ivhu uye chikamu-chakapinzwa nemvura, uye nhevedzano yemiedzo inofanirwa kuitwa apo pigment iri pasi, sekutemerwa kwehunyoro, kuita kwekupararira, kusimba kwemukati uye ruvara kunama kunaka kwejecha slurry.
Kune mana ekunyorova ekugadzirwa kwemavara masterbatch: nzira yekugeza, nzira yekukanya, sipo yesimbi, uye inki nzira.
(1) Washing method: Iyo pigment, mvura uye dispersant inoiswa jecha kuti pigment iite diki pane 1pm, uye pigment inotamiswa muchikamu chemafuta nechikamu chekufambisa nzira, yobva yaomeswa kuti iwane iyo colorbatch.Organic solvents uye inoenderana solvent kudzoreredza zvishandiso zvinodiwa pachikamu inversion.Maitiro acho ndeaya:
Pigment, dispersant, anobatsira huwandu - bhora chigayo - homogenization uye kudzikamisa kurapwa - kuomesa - resin kusanganiswa - extrusion granulation color masterbatch
(2) Kukanya nzira Mafambiro enzira yekukanya ndeaya:
Pigment, anobatsira, kukanya resin - kupera mvura - kuomesa - kusanganisa resin - extrusion granulation mu masterbatch
(3) Iyo sipo yesimbi nzira ye pigment inogayiwa kusvika pakukura kwe 1um, uye sipo inogadziriswa inowedzerwa pane imwe tembiricha kuitira kuti iyo yepasi pepigment zvidimbu zvinyoroveswe nesipo kuti igadzire musara we saponification solution. .Wedzera mhinduro yesimbi yemunyu uye pamusoro pepigment.Iyo saponification layer inopindirana nekemikari kuita chivharo chesipo yesimbi (magnesium stearate), kuitira kuti zvidimbu zvepigment zvakatsetseka zvirege kuyerera.
Maitiro ekuyerera kwesimbi sipo nzira ndeyekutevera:
Pigment, anobatsira, musanganiswa wemvura - kupatsanura uye kupera simba - kuomesa - kusanganisa resin - extrusion granulation mu masterbatch
(4) Inki nzira Mukugadzirwa kwemavara masterbatch, nzira yekugadzira inki yemavara paste inoshandiswa, kureva, kuburikidza nematatu-roll kugaya, yakaderera molecular inodzivirira layer yakaputirwa pamusoro pe pigment.Iyo yakagayiwa yakatsetseka paste inosanganiswa neinotakura resin, yobva yaiswa plasticized netwin-roll mill, uye pakupedzisira granulated ne-single-screw kana twin-screw extruder.
Iyo process inoyerera seinotevera:
Pigment, additives, dispersants, resins, solvent ingredients - three-roll mill color paste - desolventizing - resin mixing - extrusion granulation into masterbatch.
Kuyerera kwekuoma kwekugadzirwa kwemavara masterbatch: pigment (kana dhayi) inobatsira, dispersant, mutakuri - yakakwira-kumhanya kusanganisa, kubvongodza uye kuveura - mapatya-screw extrusion granulation - inotonhora kucheka uye granulation muvara masterbatch.
