Kodi mungabwezere bwanji simenti ya caulk alkalinity? Zotsatira za kuwonjezera calcium formate ndizosazolowereka?

Anthu omwe amapanga ntchito yomanga amadziwa kuti kubwerera ndi vuto lofala muzinthu za silicate. M'zaka zaposachedwa, pofuna kuchepetsa kuchitika kwa vutoli, makampani omangamanga amagwiritsa ntchito ceramic tile caulk kuti agwiritse ntchito simenti. Monga chopangira mphamvu zoyambira matope, calcium formate imagwiritsidwa ntchito kwambiri chifukwa cha mawonekedwe ake apadera, omwe amatha kufulumizitsa kuuma kwa zomangira zopangira simenti ndikuwonjezera mphamvu zoyambira zopangira simenti.

Zomwe zimapangidwira zimagawidwa kukhala zakuda zakunja zakunja zopangira khoma ndi zida zamkati zopangira khoma, ndipo kubweza kwa caustic kumachitika nthawi yachisanu yomanga chifunga kapena khoma lakunja patatha maola osachepera 24 mutamanga, kuyera kwam'deralo ndi mvula yoyera ya kristalo, zomwe zimakhudza kwambiri kukongoletsa kwa caulking mankhwala.

Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi: simenti yoyera, ufa wa putty, caulking agent, sealant ndi zina zotero. Pakati pazidazi, simenti yoyera ndi ufa wa putty ndi zida zachikhalidwe, koma zida zonsezi sizikugwira ntchito. Kugwiritsidwa ntchito kwa calcium formate ndikopambana kuposa zida zachikhalidwe.

Katundu ndi kusankha kashiamu formate

Calcium formate ndi mankhwala a ufa woyera omwe ali ndi ndondomeko ya maselo C2H2Ca04, yomwe imatha kufulumizitsa kuchuluka kwa simenti, potero kumapangitsanso mphamvu zoyamba za caulk ya simenti, motero kuwonjezera kuchuluka kwa simenti.calcium formatempaka nyengo yozizira kupanga caulk yochokera ku simenti iyenera kufulumizitsa mapangidwe a CSH gel, potero kuchepetsa kupezeka kwa alkali yobwerera.

Kupanga kwa alkali sikelo sikudzangokhudzidwa ndi malo omanga, matailosi a ceramic monga maziko nthawi zambiri amayambitsa vutoli. Kusankhidwa kwa mankhwala oyenera a calcium formate ndi mlingo ndikofunikira kwambiri kuti pakhale anti-alkali katundu wa zinthu zopangira simenti. M'nyengo yozizira yopangira ma filler ophatikiza simenti, 1-2% ya calcium formate imatha kuchepetsa kwambiri kubweza kwa alkali ya simenti yolumikizana ndi simenti.
