Dispersants kuj yog surfactants.Muaj anionic, cationic, nonionic, amphoteric thiab polymeric hom.Hom anionic siv ntau heev.Dispersing agents yog tsim rau cov hmoov los yog caking uas muaj kev cuam tshuam rau cov dej noo thiab tuaj yeem muab ntxiv kom zoo loosen thiab tiv thaiv caking yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lub cev.Nws tuaj yeem siv dav hauv txhua yam khoom noj thiab tshuaj hmoov dispersant, pub, ammonium chloride thiab lwm yam chiv dispersant, txheej dispersant, ceramic dispersant, non-phosphorus detergent, kaolin dispersant, cement additives, ntawv dispersant, circulating dej dispersant thiab scale inhibitor , thiab lwm yam. Cov khoom muaj cov nyhuv anti-deposition zoo.
Lub luag hauj lwm ntawm dispersant yog siv wetting dispersant kom txo tau lub sij hawm thiab lub zog yuav tsum tau ua kom tiav cov dispersion txheej txheem, stabilize lub dispersed pigment dispersion, hloov lub nto thaj chaw ntawm pigment hais, thiab kho lub motility ntawm pigment hais.Cov kev siv tshwj xeeb ntawm cov tshuaj dispersants tau tshwm sim hauv cov hauv qab no.
1. Rau txhua yam khoom noj thiab tshuaj hmoov, cov tshuaj dispersant muaj cov nyhuv anti-crystallization zoo heev, uas tuaj yeem ua kom cov khoom noj thiab cov tshuaj tsis zoo los ntawm kev hloov mus rau lub sijhawm ntev, thiab yog ib qho zoo heev thiab muaj kev nyab xeeb los tiv thaiv crystallization.
2. Nws yog ib qho tshuaj tiv thaiv rau cov tshuaj chiv (tshwj xeeb yog ammonium chloride, ammonium carbon), uas tuaj yeem ua kom cov nyhuv xoob ntawm cov dej noo-absorbing thiab caking thiab ua kom cov khoom zoo thiab siv sij hawm ntev.
3. Raws li cov xim dispersant, nws tuaj yeem paub txog kev sib cuam tshuam ntawm cov khoom no thiab cov xim pigment kom paub qhov dispersion ntawm cov xim thiab ua kom cov xim sib xws.
4. Raws li cov tshuaj ntxuav tes hauv cov khoom siv hluavtaws, cov khoom no muaj cov haujlwm ntawm dispersing av hais thiab calcium xab npum av, chelating multivalent hais, thiab muaj zog adsorption zog rau av hais.Txhawm rau txhim kho qhov tsis huv ntawm cov tshuaj detergent, nws yog 5 npaug ntau dua li cov tshuaj sodium tripolyphosphate uas nquag siv, thiab lub peev xwm dispersing ntawm calcium xab npum yog 6 npaug ntau dua li sodium tripolyphosphate.Nws muaj cov nyhuv tiv thaiv zoo dua, tiv thaiv cov kua qaub ntau dua li sodium tripolyphosphate.
5. scale inhibitor thiab dispersant rau txias circulating dej tuaj yeem tiv thaiv calcium carbonate, calcium carbonate scale, dispersant tuaj yeem chelate calcium ions, kom cov saturation concentration ntawm calcium ions nce ntau zaus, thaum lub concentration ntawm calcium ions siab heev, muaj. kuj tseem tuaj yeem ua cov nag lossis daus, nyob rau saum npoo ntawm cov nplai me me, tiv thaiv cov nplai los ntawm kev sib sau ua ke los ua cov khoom loj thiab nag lossis daus, txawm tias qhov tsim cov nplai txheej kuj xoob heev, yooj yim los ntxuav tawm los ntawm cov dej, yog li ntawd. ua tiav lub hom phiaj ntawm kev tiv thaiv scale, scale tshem tawm.
