Indlela yokubuyisela isiseko sesamente ye-alkalinity ye-caulk? Isiphumo sokongeza i-calcium formate ayiqhelekanga?

Abantu abenza iiprojekthi zokwakha bayazi ukuba ukubuyisela kuyingxaki eqhelekileyo kwiimveliso ze-silicate. Kwiminyaka yakutshanje, ukuze kuncitshiswe ukwenzeka kwale ngxaki eqhelekileyo, ishishini lokwakha liye lasebenzisa i-ceramic tile caulk ukuze isetyenziswe kwi-samente. Njenge-ejenti yamandla okuqala, i-calcium fomati isetyenziswa ngokubanzi ngenxa yeepropathi zayo ezizodwa, ezinokukhawulezisa izinga lokuqiniswa kweefayili ezihlangeneyo ezisekwe kwisamente kunye nokuphucula amandla okuqala eefayili ezihlangeneyo ezisekwe kwisamente.

Izinto ezicandayo zohlulwe zibe zizinto ezimnyama zangaphandle zodonga kunye nodonga lwangaphakathi lwe-caulking, kwaye ukubuyiswa kwe-caustic kaninzi kwenzeka kulwakhiwo lwenkungu yasebusika okanye udonga lwangaphandle emva kweeyure ezingaphantsi kwe-24 emva kokwakhiwa, umhlophe wendawo kunye nemvula ye-crystal emhlophe, echaphazela kakhulu umphumo wokuhlobisa wemveliso ye-caulking.

Izinto ezisetyenziswa ngokuqhelekileyo ezicaulking zezi: i-samente emhlophe, i-putty powder, i-agent ye-caulking, i-sealant kunye nokunye. Phakathi kwezi zixhobo, i-samente emhlophe kunye ne-putty powder zizinto zendabuko ze-caulking, kodwa zombini ezi zinto azikho ekusebenzeni. Ukusetyenziswa kwefomati ye-calcium kugqwesileyo kwizixhobo zemveli ze-caulking.

Iipropati kunye nokukhethwa kwefomati ye-calcium

I-calcium formate yimveliso yomgubo omhlophe kunye nefomula ye-molecular C2H2Ca04, enokukhawulezisa isantya se-hydration yesamente, ngaloo ndlela iphucula amandla okuqala e-caulk esekwe kwisamente, ngoko ke ukongeza inani elifanelekileyoicalcium formateukuya ekubunjweni kwasebusika kwe-caulk esekwe kwisamente kufuneka kukhawulezise ukubunjwa kwejeli ye-CSH, ngaloo ndlela kuncitshiswe ukwenzeka kwe-alkali yokubuyisela.

Ukuveliswa kwesikali se-alkali akuyi kuchaphazeleka kuphela kwindawo yokwakha, i-tile ye-ceramic njengoko isiseko sihlala sisona sizathu sengxaki. Ukukhethwa kweemveliso ezifanelekileyo ze-calcium formate kunye nedosi kubaluleke kakhulu ekuphuculeni ipropathi echasene ne-alkali yezinto ezidibeneyo ezisekelwe kwisamente. Kwinkqubo yokuqulunqa ebusika ye-sement-based joint filler, i-1-2% ye-calcium fomati content inokunciphisa kakhulu ukubuyiswa kwe-alkali ye-sement-based joint filler.
