Dispersant inhengo inobata kumeso ine maviri akatarisana zvimiro zve lipophilicity uye hydrophilicity mukati memorekuru.
Kupararira (Dispersion) zvinoreva musanganiswa unoumbwa nekuparadzirwa kwechinhu chimwe (kana kuti zvinhu zvakawanda) kupinda mune chimwe chinhu chiri muchimiro chezvidimbu.
Madispersants anogona kuparadzira zvakaenzana zvimedu zvakasimba uye zvemvura zve inorganic uye organic pigment izvo zvakaoma kunyungudika muzvinwiwa, uye zvakare kudzivirira sedimentation uye condensation yezvimedu, kugadzira amphiphilic reagents anodiwa kune yakagadzikana suspensions.Houhuan makemikari R & D uye kugadzirwa kwemvura-based additives uye mafuta-based additives mumaindasitiri akasiyana, ane hukama surfactant zvikamu.
Iyo yekuparadzira system yakakamurwa kuita: mhinduro, colloid uye kuturika (emulsion).Pamushonga, solute idisperant uye solvent idisperant.Semuenzaniso, muNaCl solution, dispersant is NaCl, uye dispersant imvura.Disperant zvinoreva zvinhu zvakaparadzirwa kuita zvidimbu muhurongwa hwekuparadzira.Chimwe chinhu chinonzi dispersed substance.
Mabasa ekushandisa maindasitiri pigment dispersant ndeaya anotevera:
1. Shandisa wetting dispersant kuderedza nguva uye simba rinodiwa kuti upedze kupararira, kudzikamisa yakapararira pigment dispersion, PP adhesion promoter, shandura nzvimbo yepamusoro ye pigment particles, uye kugadzirisa kufamba kwepigment particles.
2. Deredza kupindirana kwemukati pakati pemvura-mvura uye yakasimba-mvura.Dispersants zvakare ma surfactants.Dispersants ndeye anionic, cationic, isiri-ionic, amphoteric uye polymeric.Pakati pavo, anionic type inonyanya kushandiswa.
3. Kuparadzira mubatsiri wekubatsira anogona kuvandudza dispersibility yezvinhu zvakasimba kana zvemvura.
