Ọ̀ bụ ihe metụtara efflorescence na ngwa agha na hydroxypropyl methylcellulose?

Ihe ngosi nke efflorescence bụ: ihe nkịtị bụ silicate, na mgbe ọ na-ezute ikuku ma ọ bụ mmiri na mgbidi ahụ, ion silicate na-enweta mmeghachi omume hydrolysis, na hydroxide na-emepụta na-ejikọta ya na ion metal iji mepụta hydroxide na obere solubility (ihe onwunwe kemịkalụ bụ. Alkaline), mgbe okpomọkụ na-ebili, ikuku mmiri na-ekpochapụ, na hydroxide na-esi na mgbidi pụta. Site na ikpochapu mmiri nke nta nke nta, a na-agbanye hydroxide n'elu ciment siri ike. Ka oge na-aga, a na-ebuli agba ma ọ bụ agba na ihe ndị ọzọ a na-achọ mma ma ghara ịrapara n'ahụ mgbidi ahụ, na-acha ọcha, peeling na peeling ga-eme. A na-akpọ usoro a "pan-alkali". Yabụ, ọ bụghị ubiquinol nke hydroxypropyl methylcellulose kpatara.

Onye ahịa ahụ kwuru ihe dị iche iche: grout a na-efesa nke o mere ga-enwe pan-alkali n'elu mgbidi kọmpụta, ma ọ gaghị apụta na mgbidi brik a chụpụrụ, nke na-egosi na silicic acid na ciment a na-eji na mgbidi siri ike nke ukwuu (nke siri ike). alkaline nnu). Efflorescence kpatara site na evaporation nke mmiri eji na ịgba grouting. Otú ọ dị, ọ dịghị silicate na mgbidi brik a chụpụrụ na ọ dịghị efflorescence ga-eme. Ya mere, ihe omume nke efflorescence enweghị ihe jikọrọ ya na spraying.
