Zotsatira za kuwonjezera calcium formate ndizosazolowereka
Onse omwe amapanga ntchito yomanga amadziwa kuti caustic acid kubwerera ndi vuto lofala la mankhwala a tridacidacin. M'zaka zaposachedwa, pofuna kuchepetsa vuto lodziwika bwino la caustic acid kubwerera, makampani omanga agwiritsa ntchito matailosi ku 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.
The caulking zinthu amagawidwa mu mdima kunja khoma caulking zinthu ndi mkati khoma caulking zinthu, pamene caustic kubwerera nthawi zambiri kumachitika yozizira yomanga mu masiku chifunga kapena kunja khoma pambuyo kumanga pasanathe maola 24 mvula ikuwoneka yoyera pang'ono, ndipo pali mvula yoyera ya kristalo, yomwe imakhudza kwambiri kukongoletsa kwa chinthu cha caulking.
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. Kugwiritsa ntchito calcium formate ndikopambana kuposa zida zachikhalidwe,
Katundu ndi kusankha kashiamu formate
Calcium formate ndi mankhwala a ufa woyera, omwe amatha kufulumizitsa kuchuluka kwa simenti ya hydration, potero kumapangitsanso mphamvu zoyamba za simenti yochokera ku caulk, kotero kuwonjezera kuchuluka koyenera kwa calcium formate ku mapangidwe achisanu a caulk simenti ayenera kufulumizitsa kupanga gel CSH, 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 wamafila ophatikiza simenti. M'nyengo yozizira yopangira ma fillers ophatikizana ndi simenti, 1-2% ya calcium formate imatha kuchepetsa kwambiri kubweza kwa alkali wamafuta ophatikiza simenti.
