Wopanga calcium formateAojin Chemical imagawana nanu momwe calcium formate imagwiritsidwira ntchito mumakampani opanga simenti yomanga. Calcium formate yogulitsidwa ndi Aojin Chemical ili ndi 98% yambiri ndipo imapakidwa mu 25kg/thumba.
Kampani yopanga ma calcium formate, Aojin Chemical, imagawana ntchito zake mumakampani opanga simenti yomanga. Aojin Chemical imagulitsa ma calcium formate okhala ndi 98% yokwanira, yopakidwa m'matumba a 25kg.
Calcium formate (Ca(HCOO)₂), yomwe ndi chinthu cholimba kwambiri chachilengedwe, imagwiritsidwa ntchito popanga konkriti ndi simenti chifukwa cha mankhwala ake apadera. Ntchito zake zazikulu ndi ntchito zake ndi izi:
1. Mphamvu Yoyambirira ndi Kufulumira Kokhazikika
Calcium formate imafulumizitsa kwambiri kusungunuka kwa simenti, makamaka kusungunuka kwa tricalcium silicate (C₃S) ndi tricalcium aluminate (C₃A). Izi zimafulumizitsa kupangidwa ndi kukhazikika kwa zinthu zosungunuka (monga ettringite ndi calcium hydroxide), motero zimakulitsa mphamvu yoyambirira ya zinthu zopangidwa ndi simenti (mphamvu imatha kuwonjezeka ndi 20%-50% mkati mwa masiku 1-7). Kapangidwe kameneka kamaipangitsa kukhala yoyenera kwambiri pomanga kutentha kochepa (monga kuthira madzi m'nyengo yozizira) kapena kukonza mwadzidzidzi, kufupikitsa nthawi yowumitsa ndikuwonetsetsa kuti simenti imalimba bwino m'malo otentha pang'ono, motero kupewa kuwonongeka kwa kuzizira.
2. Konkriti Yogwira Ntchito Bwino Ndi Yolimba
Mu simenti, calcium formate imachepetsa kutuluka magazi ndi kulekanitsa, ndikuwonjezera kufanana ndi kuchulukana kwa simenti. Kuphatikiza apo, zinthu zake zothira madzi zimadzaza ma pores a simenti, kuchepetsa ma porosity, mwanjira ina kuwonjezera kukana kwa simenti, kukana chisanu, komanso kukana dzimbiri, motero zimakulitsa moyo wa ntchito ya zinthu za simenti.
3. Yoyenera kugwiritsa ntchito zinthu zosiyanasiyana za simenti
Pakupanga zinthu zopangidwa kale, monga mapanelo opangidwa kale ndi mapaipi, calcium formate imathandizira kusintha kwa nkhungu, kuchepetsa nthawi yochotsa zinthu, komanso kukonza bwino ntchito yopangira.
Shotcrete: Imagwiritsidwa ntchito popopera mankhwala m'matanthwe, m'migodi, ndi mapulojekiti ena, imakhazikika mwachangu ndikulimba, kuchepetsa kutayika kwa madzi obwerera m'mbuyo ndikuwonjezera magwiridwe antchito omanga.
Zipangizo za matope ndi miyala: Zimathandiza kusunga madzi ndi mphamvu ya matope, zomwe zimathandiza kuti ntchito za miyala ndi pulasitiki zipite patsogolo mwachangu.
4. Ubwino wa Zachilengedwe ndi Kugwirizana
Mtengo wa Calcium FormateSichimayambitsa poizoni komanso sichikwiyitsa, ndipo chimagwirizana ndi simenti, zinthu zochepetsera madzi, phulusa la ntchentche, ndi zinthu zina zosakaniza. Sichimayambitsa mavuto monga alkali-aggregate reaction mu konkire, zomwe zimakwaniritsa zosowa za kapangidwe ka zinthu zobiriwira. Dziwani: Mlingo wa calcium formate uyenera kulamulidwa mosamala (nthawi zambiri 1%-3% ya simenti). Kuwonjezera kwambiri kungachedwetse kukula kwa mphamvu ya konkire pambuyo pake komanso kungayambitse ming'alu. Kusintha kuyenera kupangidwa kutengera zinthu monga malo a polojekiti ndi mtundu wa simenti.
