Kurapa kwepamusoro kwe inorganic pigments

Mushure mekurapwa kwepamusoro kwe inorganic pigment, kushanda kwe pigment kunogona kuvandudzwa, uye mibairo yacho inoratidza zvizere maitiro ayo ekuona, ndiyo imwe yematanho makuru ekuvandudza giredhi remhando ye pigment.

Basa rekurapa kwepamusoro

Mhedzisiro yekurapa kwepamusoro inogona kupfupikiswa muzvikamu zvitatu zvinotevera:

1. kuvandudza zvimiro zvepigment pachayo, senge simba remavara uye simba rekuhwanda;
2.  kunatsiridza mashandiro, uye kuwedzera dispersibility uye kupararira kugadzikana kweiyo pigment mune solvent uye resin;
3.  kunatsiridza iyo pigment yekupedzisira zvinhu kusimba, kugadzikana kwemakemikari uye processability.

Kurapa kwepamusoro kweiyo pigment kunogona kuitwa nejasi remukati uye kuwedzera organic pamusoro-inoshanda maajenti kuti aite chinhu chayo, semuenzaniso:

Chrome yero inozvimba zviri nyore mukugadzira, kuita gobvu kana toner ichiita "silika", nekuwedzera zinc sipo, aluminium phosphate, aluminium hydroxide kuderedza coarse acicular crystals, kudzika kuzvimba chiitiko; lead chrome yellow pigments inogona kushandiswa antimony compound kana isingawanzo pasi kana silica pamusoro inobatwa kuti ivandudze mwenje wayo, kudzivirira kupisa uye kugadzikana kwemakemikari; cadmium yero yepamusoro nzvimbo inogona kuwedzerwa kuburikidza neSiO2, Al2O3 kurapa kwepamusoro, kuwedzera kupikisa kwemamiriro ekunze, inogonawo kuwedzerwa sodium stearate, alkyl sulfonates, nezvimwewo kusvika kumusoro kubva kuhydrophilic kuenda ku lipophilic uye nyore kupararira muresin;

Cadmium tsvuku neAl2O3, SiO2 yakavharidzirwa pamusoro pekurapa inogona zvakare kuvandudza kwayo dispersibility uye kuramba mamiriro ekunze;
Iron oxide pigment inogona kunge yakabatwa pamusoro ne stearic acid agent kuti ivandudze dispersibility yayo mune organic medium, iyo yepamusoro kurapwa inogonawo kuva Al2O3, oleophilic pamusoro pekusimudzira kushanda;

Transparent yellow iron oxide, inogona kuvandudza dispersibility uye pachena nekuwedzera sodium dodecyl naphthalene pamusoro kurapwa;

Iron blue pigments yakashata alkali resistance, alkali resistance inogona kukwidziridzwa nemafuta ayo amine surface kurapwa;
Ultramarine murombo acid resistance, asidhi inogona kuvandudza kushanda kwayo neSiO2 pamusoro pekurapa;
Lithopone Lithopone mu zinc sulfide inogona kuderedzwa nephotochemical chiitiko chezvisingawanzo pasi zvinhu mukurapa kwepamusoro.
