Simenti ndi ndiwo zamasamba, kuchuluka kwa ntchito ya calcium formate ndi chiyani, ubwino wake ndi wotani?

Calcium formatesi mawu achilendo kwambiri, kugwiritsa ntchito kashiamu formate mu makampani ndi mochulukira, koma kuwonjezera pa ulimi alibe malo ochepa chitukuko. Amagwiritsidwa ntchito mu simenti popangira mphamvu zoyambira, zomwe zimagwiritsidwa ntchito mumasamba a calcium, chifukwa chiyani calcium formate imagwiritsidwa ntchito kwambiri, maubwino ake ndi ati?
Pogwiritsidwa ntchito m'mafakitale, formic acid mucalcium formatendi asidi ofooka, madzi sungunuka alkali. Simenti, zitsulo, konkire ndi zina zotero mu ntchito yomanga ya magulu wamba ndi kashiamu formate chithunzi. Pogwiritsidwa ntchito m'mafakitale, kuthekera kofulumizitsa mphamvu ya hydration ndikwabwino kwambiri, ndipo mphamvu yoyambirira yamatope owuma idzawuka. Chifukwa chake, kugwiritsa ntchito mawonekedwe abwino kwambiri a calcium kumakhudza kwambiri kubereka.

Pamene ntchitocalcium formate, madzi amatha kuchepetsedwa momwe angathere. Komanso, solubility wa kashiamu formate ndi dispersibility mu matope, ndi ntchito oyambirira ufa youma adzakhudzidwa ndi zili mankhwala,
Osiyana zikuchokera zili kashiamu formate ntchito zosiyanasiyana mbali, mwachitsanzo, ntchito zomangamanga matope, pulasitala matope osiyanasiyana osiyanasiyana. Zoonadi, kugwiritsa ntchito nthawi yachisanu ndi chilimwe sikufanana.
Pambuyo ntchito zosiyanasiyana zili kashiamu formate kufika kalasi inayake, chomangira mphamvu ya pulasitala matope pang`onopang`ono kumawonjezeka ndi kuwonjezeka kwa mlingo wake. Komabe, ngati calcium formate yochuluka iwonjezeredwa panthawi imodzi, liwiro la condensation ya simenti lidzapangidwa pamene ikugwira ntchito, yomwe imakhala yosavuta kusweka. Choncho, pamene ntchito kashiamu formate makampani, tiyenera kukhala ndi chiyembekezo cha kutentha, ndi chiyembekezo cha mphamvu ya matope kusintha mmwamba ndi pansi, malinga ndi mmene zinthu kusintha.
Mukukula masamba, kugwiritsa ntchito calcium formate kumatha kuwongolera kutuluka kwa zinthu muzamasamba. Ambiri, zili kashiamu masamba zomera zosakwana asafe ndi potaziyamu, ndi apamwamba kuposa phosphorous, magnesium ndi sulfure. Kugwiritsa ntchito bwino kashiamu formate akhoza bwino kulimbikitsa synthesis wa mapuloteni ndi chakudya mu zomera, ndi ntchito zabwino kashiamu formate ali ndi mbali yaikulu mu neutralization wa organic zidulo mu masamba.

Kuphatikiza pa magawo awiriwa, pali malo ambiri komwecalcium formateimatha kuchitapo kanthu, ndipo imagwiritsidwa ntchito pomanga mafakitale, zomwe sizingawononge zitsulo zamkati, komanso zimatha kukulitsa mphamvu ya simenti. Itha kulowa m'malo mwa chigawo cha calcium chloride chomwe chidagwiritsidwa ntchito m'mbuyomu ndikuchita ntchito yakeyake yopindulitsa
