Dispersant tseem hu ua ntub dej thiab dispersing tus neeg sawv cev. Ntawm ib sab tes, nws tau ntub cov nyhuv, ntawm qhov tod tes, ib qho kawg ntawm cov pab pawg ua haujlwm tau adsorbed rau hauv cov khoom siv los ua cov txheej txheem adsorption (tus ntxiv cov pab pawg ua tiav, cov txheej txheem adsorption) los tsim cov xim ntxiv) lossis cov xim dej ua kom tawg tuaj yeem raug xa tawm thiab tshem tawm hauv cov xim rau lub sijhawm ntev kom tsis txhob flocculation dua. Qhov no ua kom muaj kev cia khoom ruaj khov ntawm cov xim txheej txheem.
Hom feem ntau siv ntawm dispersants.
1.Anionic ntub thiab dispersing tus neeg sawv cev
Feem ntau ntawm lawv yog tsim los ntawm tsis-polar, tsis zoo them hydrocarbon saw thiab polar hydrophilic pab pawg. Ob pawg yog nyob ntawm ob xaus ntawm lub molecule, sib sau ua asymmetric hydrophilic thiab oleophilic molecular qauv. Nws cov ntau yam yog: sodium 000 FeatE C17h33Coona, sulfate, thiab lwm yam ntawm cov roj ntsha tau zoo, thiab lwm yam. Siv tau rau cov kuab tshuaj polymers Thiab dav siv raws li tswj flocculation-hom dispersants.
2.cationic ntub thiab dispersing tus neeg sawv cev
Lawv tsis yog-polar paus Possentively raug foob, feem ntau yog cov ntsev ua kom zoo nkauj, thiab cov roj av zoo dua, tab sis nws yuav tsum tau sau tseg Tias lawv hnov qab siv tshuaj nrog cov pab pawg carboxyl hauv cov khoom siv hauv paus, thiab tseem nco ntsoov tias lawv yuav tsum tsis txhob siv ib txhij nrog anionic dispersants.
3.Cov tau dawb radical hom hyperdispersant
Thib ob, lub luag haujlwm ntawm dispersant
1.Nim cov kab thiab nce cov nyhuv qib.
2.Prevent ntab xim thiab ua paj.
3.Nimrove pelling zog.
4. Raug txawv viscosity thiab nce xim chaw thau khoom.
5. Raug tshem tawm flocculation, nce kev tsim khoom thiab siv tau.
6.Txoj kev ua kom muaj zog thiab nce cia khoom ruaj khov.
7.Muaj xim xim kis thiab xim xim.
8.Muaj phau ntawv lossis npog lub hwj chim.
9.Txoj kev sib tsoo sib tsoo thiab txo tus nqi tsim.
10.Prevent daws teeb meem.
