Na ketsahalo ea efflorescence ka seretseng e amana le hydroxypropyl methylcellulose?

Ketsahalo ea efflorescence ke: konkreite e tloaelehileng ke silicate, 'me ha e kopana le moea kapa mongobo leboteng, silicate ion e kenella karabelo ea hydrolysis,' me hydroxide e hlahisoang e kopana le li-ion tsa tšepe ho etsa hydroxide e nang le solubility e tlase (thepa ea lik'hemik'hale ke Alkaline), ha mocheso o phahama, mouoane oa metsi oa fetoha mouoane, 'me hydroxide e theoha leboteng.Ha metsi a fetoha mouoane butle-butle, hydroxide e theoha holim'a samente ea konkreite.Ha nako e ntse e ea, pente ea pele e khabisitsoeng Kapa pente le lintho tse ling li phahamisoa 'me ha li sa khomarela lerako,' me ho tla ba le bosoeu, ho phunya le ho senya.Ts'ebetso ena e bitsoa "pan-alkali".Kahoo, ha se ubiquinol e bakoang ke hydroxypropyl methylcellulose.
