xov xwm

Dispersant yog ib hom interfacial active neeg sawv cev, uas muaj lipophilic thiab hydrophilic zog nyob rau hauv molecules. Nws tuaj yeem cuam tshuam cov khoom thiab cov kua dej ntawm cov inorganic thiab organic pigments uas nyuaj rau yaj hauv cov kua, tiv thaiv particle sedimentation thiab condensation, thiab tsim ob hom philophile reagents xav tau rau kev ncua ruaj khov.Dispersing tus neeg sawv cev MF

Ib qho surfactant yog ib yam khoom uas tuaj yeem txo qhov nro ntawm lub hom phiaj. Nws muaj ib pawg roj hydrophilic ruaj khov uas tuaj yeem taw qhia rau saum npoo ntawm cov tshuaj. Cov qauv molecular ntawm surfactants muaj ob lub zog: ib kawg yog pawg hydrophilic, lwm qhov kawg yog pawg hydrophobic; Hydrophilic pawg feem ntau yog pawg polar, xws li sulfonic acid, carboxylic acid, sulfuric acid, amino lossis amine pawg thiab lawv cov ntsev, amide pawg, hydroxyl pawg, ether bonds, thiab lwm yam, kuj tuaj yeem siv los ua pawg polar hydrophilic; Cov pab pawg hydrophobic feem ntau yog cov saw hlau tsis muaj polar hydrocarbon, xws li cov uas muaj ntau tshaj 8 carbon atoms. Surfactants tau muab faib ua ionic surfactants (xws li cationic surfactants thiab anionic surfactants), composite surfactants, amphoteric surfactants, non-ionic surfactants, lwm yam surfactants thiab lwm yam.

Cov dispersants ua haujlwm li cas!

Dispersing tus neeg sawv cev MFntseeg tias txhua tus tsis paub tsis meej, peb tau tham ntau txog pem hauv ntejDispersing tus neeg sawv cev MFcov ntaub ntawv, yog li dab tsi yog txoj hauv kev ua haujlwm ntawm dispersant? Yog tias koj tseem tsis tau paub txog qhov kev paub no, peb tuaj yeem kawm txog txoj hauv kev ua haujlwm ntawm cov neeg tawg rog ua ke!

Dispersant txoj cai:

1, nqus tau rau ntawm qhov chaw ntawm cov khoom, txo qhov nro ntawm cov kua - kua lossis khoom-kua. Qhov saum npoo ntawm cov khoom condensed yog yooj yim rau ntub.

2, cov khoom siv polymer hom dispersant, nyob rau saum npoo ntawm cov khoom siv tsim cov txheej txheem adsorption, kom tus nqi ntawm cov khoom seem ntawm cov khoom nce, txhim kho lub zog recoil ntawm cov khoom ntawm peb-seem thaiv.

3, ua rau saum npoo ntawm cov khoom ua kom tsim ob chav molecular qauv txheej txheej, nto dispersant zoo thiab tsis zoo heev muaj ib tug muaj zog affinity nrog dej, txhim kho theem ntawm cov khoom uas ntub dej los ntawm dej. Qhov nruab nrab ntawm cov khoom siv yog zam los ntawm electrostatic inductive repulsion.

4, ua rau kev tswj hwm qhov sib luag, cov yam ntxwv ntab, tsis muaj qhov tso tawm, kom tag nrho cov kev tswj hwm cov tshuaj lom neeg cov yam ntxwv. Saum toj no, daim ntawv thov ntawm dispersant yuav stably disperse khoom hais nyob rau hauv lub xeev cov kua.
