Moemeli oa ho qhalakanya MFo lumela hore motho e mong le e mong ha a tsebe, re buile haholo ka pel'aMoemeli oa ho qhalakanya MFtlhahisoleseling, kahoo molao-motheo oa ho sebetsa oa dispersant ke ofe? Haeba u ntse u sa tloaelane le tsebo ena, re ka ithuta ka molao-motheo oa ho sebetsa oa dispersants hammoho!

Molao-motheo oa dispersant:

1, monya holim'a likaroloana tse tiileng, fokotsa tsitsipano ea holim'a metsi - metsi kapa metsi a tiileng. Bokaholimo ba likaroloana tse tiileng tsa condensed ho bonolo ho koloba.

2, mofuta oa thepa ea polymer ea dispersant, holim'a likaroloana tse tiileng li hlahisa lera la adsorption, e le hore tefiso ea bokaholimo ba likaroloana tse tiileng e eketsehe, e ntlafatse matla a ho qhekella pakeng tsa likaroloana tsa ho thibela likarolo tse tharo.

3, etsa hore bokaholimo ba likaroloana tse tiileng li hlahise sebopeho sa lera la limolek'hule tse habeli, maemo a holimo a fapaneng a nepahetseng le a mabe a na le kamano e matla le metsi, a ntlafatsa boemo ba likaroloana tse tiileng tse kolobisitsoeng ke metsi. Bohareng ba likaroloana tse tiileng li qojoa ka ho reteleha ha electrostatic inductive.

4, etsa hore tsamaiso ea tsamaiso symmetrical, phaphametseng litšobotsi, ha ho deposition, e le hore tsamaiso eohle ea tsamaiso organic lik'hemik'hale litšobotsi. Ka holimo, ts'ebeliso ea dispersant e ka qhala ka mokhoa o tsitsitseng likaroloana tse tiileng sebakeng sa mokelikeli.
