Calcium formate imagwiritsidwa ntchito ngati chothandizira mphamvu zoyambirira
Calcium formateimagwiritsidwa ntchito ngati mankhwala oyambira,
alcium formate, calcium formate woyamba mphamvu wothandizira, calcium formate imagwiritsa ntchito opanga mapangidwe a calcium, chakudya chamagulu a calcium,
Physicochemical katundu:
1.White crystal kapena ufa, kuyamwa pang'ono chinyezi, kulawa zowawa. Wosalowerera ndale, wopanda poizoni, wosungunuka m'madzi.
2.Kuwola kutentha: 400 ℃
Posungira:
Kusamala kosungirako, mpweya wabwino wa nyumba yosungiramo zinthu komanso kuyanika kutentha kochepa.
Gwiritsani ntchito
1. Dyetsani Gulu la Calcium Formate:Dyetsani Zowonjezera
2. Magulu a Calcium Formate:
(1) Ntchito Yomanga: Pakuti simenti, monga coagulant, lubricant;Kumanga matope, kuti mathamangitsidwe kuumitsa simenti.
(2) Kugwiritsa Ntchito Zina: Zachikopa, zotsutsana ndi kuvala, ndi zina

Monga mtundu watsopano wothandizira mphamvu zoyamba, calcium formateosati imathandizira kuuma kwa simenti, komanso kumapewa kutsika kwapang'onopang'ono pomanga m'nyengo yozizira kapena pansi pa kutentha kochepa ndi chinyezi, kumathandizira kwambiri ku mphamvu yoyambirira ya simenti kuti igwiritsidwe ntchito posachedwa. Kwa nthawi yayitali, calcium kolorayidi yakhala ikugwiritsidwa ntchito kwambiri mu uinjiniya, koma imatha kuwononga zitsulo, chlorine wopanda coagulant yapangidwa kunyumba ndi kunja, ndipo kashiamu formate ndi mtundu watsopano wazinthu zoyambira mphamvu, zimatha kufulumizitsa hydration ya tricalcium silicate C3s mu simenti ndi kuonjezera mphamvu oyambirira a simenti matope, koma sizidzachititsa dzimbiri mipiringidzo zitsulo ndipo sikudzachititsa kuipitsa chilengedwe, Choncho, amagwiritsidwanso ntchito kwambiri pobowola mafuta munda ndi simenti. Mankhwala makhalidwe: kufulumizitsa kuumitsa simenti, kufupikitsa nthawi yomanga. Kufupikitsa nthawi yoyika, kuumba koyambirira. Kulimbikitsa oyambirira mphamvu ya matope pa otsika kutentha. Antifreeze ndi antirust. Mankhwala buku luso katundu ndi makhalidwe kashiamu formate ndi woyera kapena imvi woyera crystalline ufa. Pansi pa chikhalidwe chochiritsa, mankhwalawa amatha kupanga konkire komaliza mkati mwa maola 4. Mphamvu ya konkire yoponyedwa m'malo imatha kufika pa 5MPA pambuyo pa maola 8, ndipo konkire yoponyedwa m'malo imatha kugwetsedwa bwino. Ngakhale kuonetsetsa mphamvu yoyambirira ya matope ndi konkire, imatha kupanga mphamvu yochedwa ya matope ndi konkire ikuwonjezeka kawirikawiri ndipo ilibe zotsatira zowononga pazinthu zina zamakono zamatope ndi konkire.
