Ingabe ukwenzeka kwe-efflorescence odakeni kuhlobene ne-hydroxypropyl methylcellulose?

Isenzo se-efflorescence siwukuthi: ukhonkolo ojwayelekile uyi-silicate, futhi lapho uhlangana nomoya noma umswakama odongeni, i-ion silicate ithola ukusabela kwe-hydrolysis, futhi i-hydroxide ekhiqizwayo ihlangana nama-ion ensimbi ukwenza i-hydroxide ene-solubility ephansi (impahla yamakhemikhali I-alkaline), lapho izinga lokushisa likhuphuka, umhwamuko uyahwamuka, futhi i-hydroxide idonswa odongeni. Ngokuhwamuka kwamanzi kancane kancane, i-hydroxide iyawa phezu kukasimende kakhonkolo. Ngokuhamba kwesikhathi, upende wangempela wokuhlobisa Noma upende nezinye izinto ziyaphakanyiswa futhi azisanamatheli odongeni, futhi ukucwenga, ukucwecwa, nokucwecwa kuzokwenzeka. Le nqubo ibizwa ngokuthi "i-pan-alkali". Ngakho-ke, akuyona i-ubiquinol ebangelwa i-hydroxypropyl methylcellulose.

Ikhasimende lithe into eyenzekile: i-grout efuthwe elenzile izoba ne-pan-alkali odongeni lukakhonkolo, kodwa ngeke ivele odongeni lwesitini esibasiwe, okubonisa ukuthi i-asilicic acid kusimende esetshenziswa odongeni lukakhonkolo Usawoti omningi (ngokunamandla. usawoti we-alkali). I-efflorescence ebangelwa ukuhwamuka kwamanzi asetshenziswa ku-spray grouting. Kodwa-ke, ayikho i-silicate odongeni lwezitini ezishisiwe futhi akukho i-efflorescence ezokwenzeka. Ngakho-ke, ukwenzeka kwe-efflorescence akuhlangene nokufafaza.

Isixazululo

1. Okuqukethwe kwe-silicate ye-base concrete sement kuyancipha.

2. Sebenzisa i-anti-alkali back coating agent, isisombululo singena etsheni ukuvimba i-capillary, ukuze amanzi, i-Ca (OH) 2, usawoti nezinye izinto zingakwazi ukungena, futhi zinqume indlela ye-pan-alkaline phenomenon.

3. Ukuvimbela ukungena kwamanzi, ungafafazi amanzi amaningi ngaphambi kokwakhiwa.

Ukwelashwa kwe-pan-alkaline phenomenon

I-ejenti yokuhlanza i-stone efflorescence emakethe ingasetshenziswa. Le ejenti yokuhlanza iwuketshezi olushintshayo olungenambala olwenziwe ngama-non-ionic surfactants nezincibilikisi. Kunomthelela othile ekuhlanzeni ezinye izindawo zamatshe zemvelo. Kodwa ngaphambi kokusebenzisa, qiniseka ukuthi wenza isampula encane yokuhlola ibhulokhi ukuze uhlole umphumela futhi unqume ukuthi uzoyisebenzisa yini.
