Cov dispersion ntawm pigments yog ib qib tseem ceeb hauv ntau qhov kev lag luam, kom muaj kev faib cov xim zoo nkauj thiab ruaj khov nyob rau hauv cov khoom kawg. Ua tiav ib qho txawm dishension txhim kho qhov zoo thiab muaj tshwm sim ntawm cov xim tha xim, inks, txheej, thiab lwm yam kev siv. Ntawm no yog ib tug txheej txheem cej luam ntawm txheej dispersion:
1.PRE -} ntub dej
Pigments yog feem ntau xa hauv daim ntawv hmoov qhuav. Los npaj lawv rau dispersion, lawv yogua ntej -} wettednyob rau hauv cov kuab tshuaj los yog cob. Qhov kev pib ntub dej yuav pab ua kom tawg thiab yuam kev, ua rau cov khoom kom yooj yim rau kev tsis sib xws.
2.Mixing thiab ntxhov siab
Lub pre {- wetted pigments yog tau kawm rau hauv cov khoom siv los yog dispersing cov khoom sib txuas nrog rau lwm yam ntawm cov qauv, xws li binders, cov kuab tshuaj, thiab ntxiv.Kev Txom Nyemyog thov kom rhuav tshem cov xim pigment agglomerates thiab xyuas kom meej homogeneous sib xyaw. Siab - ceev dispersers, pob zeb ua pob, lossis hlaws av feem ntau siv rau lub hom phiaj no.
3.Shearing thiab sib tsoo
Thaum lub sij hawm dispersion, cov sib tov undergoesshearing thiab sib tsooCov. Siab - shear cov cuab yeej kawm cov xim xim rau cov zog hluav taws xob, ua kom lawv poob qis dua. Cov kauj ruam no yog qhov tseem ceeb rau kev ua tiav kev sib cais zoo thiab kev sib cais.
4.Raws cai
Txhawm rau tiv thaiv rov - agglomeration ntawm cov khoom me me,stabilizerslossisDispersing cov neeg sawv cevmuaj ntxiv. Cov tshuaj no tsho tiv thaiv lub ntsej muag xim pig, tsim ib qho kev thaiv uas tiv thaiv cov lus los ntawm clumping ua ke. Dispersing cov neeg sawv cev tuaj yeem surfactants, polymers, lossis lwm yam tshuaj tshwj xeeb ua rau cov xim tshwj xeeb.
8.Qhov kev tswj
Thoob plaws hauv cov txheej txheem dispersion,Kev Tswj Xyuas Zookev ntsuas tau ua tiav. Kev txheeb xyuas me me thiab kuaj pom cov qauv siv tau ntau yam los ua kom muaj kev rho tawm kom ntseeg tau tias muaj cov kev xav tau zoo. Txoj kev hloov kho tau tuaj yeem ua rau cov txheej txheem tsis yog yog tias xav tau.
6.Final kev kho
Tom qab ua tiav cov kev xav tau qhov xav tau, cov khoom sib xyaw ntxiv xws li cov kev siv tshuab hluav taws xob, rhuaology modifemers, lossis ntxiv ntxiv cov kev sib ntxiv ntawm cov kev xav tau ntawm cov ntawv thov. Cov khoom sib xyaw ua ke zoo - saib cov qauv tsim rau kev ua tau zoo tshaj plaws.
Hauv cov ntsiab lus, cov txheej txheem dispersion cuam tshuam nrog ua ntej - ntub dej, sib xyaw, tswj kom zoo, cov kauj ruam kev kho kom zoo, zaum kawg. Txhua theem yog qhov tseem ceeb heev nyob rau hauv ensuring ib qho kev sib xws thiab ruaj ntseg dispersion, ua rau siab- Cov khoom lag luam zoo kawg hauv ntau cov ntawv thov.
