Dispersant chinhu chinoshanda pakati pema "interfacial" chine zvinhu zviviri zvakasiyana zve "lipophilicity" uye "hydrophilicity" mukati memorekuru.

Kupararira zvinoreva musanganiswa unoumbwa nekupararira kwechinhu chimwe (kana zvinhu zvakawanda) kuenda kune chimwe chinhu muchimiro chezvidimbu.

Zvinoparadzira zvinogona kuparadzira zvakaenzana zvidimbu zvakasimba uye zvemvura zvepigment inorganic uye organic zvinonetsa kunyungudika mumvura, uye zvakare kudzivirira kudonha uye kuungana kwezvidimbu, zvichigadzira amphiphilic reagents dzinodiwa kuti pave nekumira kwakasimba. Houhuan chemical R & D uye kugadzirwa kwezvinowedzera zvinobva mumvura uye zvinowedzera zvinobva mumafuta mumaindasitiri akasiyana-siyana, zvine chekuita nezvikamu zve surfactant.

Sisitimu yekupararira yakakamurwa kuita: mhinduro, colloid uye suspension (emulsion). Kune mhinduro, solute idispersant uye solvent idispersant. Semuenzaniso, muNaCl solution, dispersant iNaCl, uye dispersant imvura. Dispersant inoreva zvinhu zvakapararira kuita zvidimbu mu dispersion system. Chimwe chinhu chinonzi dispersed substance.

Mabasa ekushandisa industrial pigment dispersant ndeaya anotevera:

1. Shandisa wetting dispersant kuderedza nguva nesimba rinodiwa kuti upedze kupararira, kugadzirisa kupararira kwepigment, PP adhesion promoter, kugadzirisa hunhu hwepamusoro hwepigment particles, uye kugadzirisa kufamba kwepigment particles.

2. Deredza kushushikana pakati pemvura-mvura uye solid-liquid. Zvinoparadzanisa zvinhu zvakare zvinoshandisa ma surfactants. Zvinoparadzanisa zvinhu izvi zvinoshandisa anionic, cationic, non-ionic, amphoteric uye polymeric. Pakati pazvo, mhando yeanionic ndiyo inonyanya kushandiswa.

3. Kuparadzira chinhu chinobatsira chinogona kuvandudza kupararira kwezvinhu zvakasimba kana zvemvura.
