Zvinonyungudutsa zvinhu zvinoshandiswa pakugadzira zvinhu zvakasimba muzvinhu zvakaita sema glue, pendi, mapurasitiki uye mapurasitiki akabatanidzwa.

Kare, machira aisada ma dispersants. Masisitimu akadai sealkyd ne nitro pendi aisada ma dispersants. Ma dispersants haana kuonekwa kusvika pa acrylic resin pendi ne polyester resin pendi. Izvi zvine chekuitawo nekugadzirwa kwe pigments, nekuti kushandiswa kwe pigments dzemhando yepamusoro hakugone kuparadzaniswa nerubatsiro rwema dispersants.
Zvinodimbura zvinhu zvinoshandiswa pakugadzira zvinhu zvinosimbisa mativi akaoma muzvinhu zvakaita sema glue, pendi, mapurasitiki uye mapurasitiki akabatanidzwa. Mugumo wayo icheni yekunyungudutsa inogona kunyungudutswa muzvinhu zvakasiyana-siyana zvinodimbura, uye mumwe mugumo iboka rinonamira pigment rinogona kunyungudutswa pamusoro pemavara akasiyana-siyana uye kushandiswa kushandura kuita solid/liquid interface (pigment/resin solution).

Mhinduro yeresin inofanira kupinda munzvimbo dziri pakati pema "pigment agglomerates". Ma "pigment" ese aripo se "pigment agglomerates", ayo ari "muunganidzwa" we "pigment" zvidimbu, nemhepo nehunyoro zviri munzvimbo dziri mukati pakati pe "pigment" zvidimbu zve "pigment" imwe neimwe. Ma "particles" ari kusangana pamipendero nemakona, uye kudyidzana pakati pe "particles" kudiki, saka masimba aya anogona kukundwa nemidziyo yekupararira. Kune rumwe rutivi, ma "agglomerates" akaomesesa, uye pane kusangana chiso nechiso pakati pe "pigment" zvidimbu, saka zvakaoma zvikuru kuaparadzira mu "primary particles". Munguva yekukuya kwe "pigment dispersion", "pigment agglomerates" inova diki zvishoma nezvishoma; mamiriro akanaka ndeekuwana "primary particles".

Maitiro ekukuya pigment anogona kukamurwa kuita matanho matatu anotevera: danho rekutanga kunyorovesa. Pasi pekukurunga, mhepo yese nehunyoro pamusoro pepigment zvinobuda uye zvinotsiviwa ne resin solution. Dispersant inovandudza kunyorova kwepigment, ichishandura solid/gas interface kuita solid/liquid interface uye ichivandudza kushanda kwegrinding; danho rechipiri maitiro chaiwo ekukuya pigment dispersion. Kuburikidza ne mechanical energy impact uye shear force, pigment agglomerates dzinopwanyika uye saizi ye particle inoderedzwa kuita primary particles. Kana pigment yavhurwa ne mechanical force, dispersant ichakurumidza kunyudza nekuputira small particles; mudanho rechitatu rekupedzisira, pigment dispersion inofanira kunge yakagadzikana zvakakwana kudzivirira kuumbwa kwe flocculation isingadzoreki.

Kushandisa muchina wekuparadzanisa wakakodzera kunogona kuchengetedza zvidimbu zvepigment zviri kure nekwazvo pasina kudzoreredza kubatana. Muzvizhinji zvezvinoshandiswa, mamiriro ekubvisa flue akasimba anodiwa. Mune zvimwe zvinoshandiswa, kupararira kwepigment kunogona kuramba kwakasimba pasi pemamiriro ekudzivirira flue anodzora. Zvishandiso zvekunyorovesa zvinogona kuderedza musiyano wekumanikidzwa kwepamusoro pakati pepigment ne resin solution, zvichikurumidzisa kunyorovesa kwezvibatanidzwa zvepigment ne resin; zvinobatsira zvekuparadzanisa zvinowedzera kugadzikana kwekupararira kwepigment. Nokudaro, chigadzirwa chimwe chete chinowanzova nebasa rekubatsira kunyorovesa nekuparadzira.

Kupararira kwepigment inzira inobva pakusanganiswa kusvika pakupararira. Sezvo saizi yezvikamu ichiderera uye nzvimbo yepamusoro ichiwedzera, simba repamusoro rehurongwa rinowedzerawo.
Sezvo simba repamusoro pesisitimu richingodzikira, kuwedzera kwenzvimbo yepamusoro kunonyanya kuoneka, simba rakawanda rinodiwa kuti rishandiswe kubva kunze panguva yekukuya, uye simba rakasimba remuchina wekuparadzanisa rinodiwa kuchengetedza kugadzikana kwekupararira kwesisitimu. Kazhinji, mavara asina kugadzirwa ane saizi yakakura yezvikamu, nzvimbo dzakaderera dzepamusoro, uye polarity yepamusoro yenzvimbo, saka zviri nyore kuparadzira nekudzikamisa; nepo mavara akasiyana-siyana eorganic nekabhoni dema aine saizi diki dzezvikamu, nzvimbo dzakakura dzepamusoro, uye polarity yakaderera yenzvimbo, saka zvinonetsa kuparadzira nekudzikamisa.

Saka, zvinoparadzira zvinhu zvinonyanya kupa zvinhu zvitatu zvekushanda: (1) kuvandudza kunyorovesa kwepigment uye kuvandudza kushanda zvakanaka kwekukuya; (2) kuderedza kusimba kweganda uye kuvandudza kuenderana nechinhu chepasi, kuvandudza kupenya, kuzara uye kusiyanisa kwemufananidzo, uye kuvandudza kugadzikana kwekuchengetera; (3) kuwedzera simba rekupenda pigment uye huwandu hwepigment uye kuvandudza kugadzikana kwekupenda mavara.

Nanjing Reborn New Materials inopamushonga wekunyorovesa pendi nependi, kusanganisira zvimwe zvinoenderana neDisperbyk.

In chinyorwa chinotevera, tichaongorora mhando dzezvinoparadzira munguva dzakasiyana nenhoroondo yekugadzirwa kwezvinoparadzira.
