Mugadziri weCalcium FormateAojin Chemical inokupaiwo mashandisirwo ecalcium formate muindasitiri yesimende yekuvaka. Calcium formate inotengeswa neAojin Chemical ine huwandu hwakawanda hwe98% uye inoiswa mu25kg/bhegi.
Kambani inogadzira calcium formate Aojin Chemical inoshandisawo calcium formate muindasitiri yekuvaka simende. Aojin Chemical inotengesa calcium formate ine huwandu hwakanyanya hwe98%, yakaputirwa mumabhegi e25kg.
Calcium formate (Ca(HCOO)₂), chinhu chinoshanda zvikuru mukugadzira kongiri nesimende, chinoshandiswa mukugadzira zvigadzirwa zvekongiri nesimende nekuda kwehunhu hwayo hwemakemikari hwakasiyana. Mabasa ayo makuru uye mashandisirwo ayo ndeaya anotevera:
1. Simba Rekutanga uye Kukurumidza Kwemamiriro
Calcium formate inokurumidza zvikuru kunyorovesa simende, kunyanya kunyorovesa kwe tricalcium silicate (C₃S) uye tricalcium aluminate (C₃A). Izvi zvinokurumidzisa kuumbwa nekugadzika kwezvigadzirwa zve hydration (zvakadai se ettringite ne calcium hydroxide), nokudaro zvichivandudza simba rekutanga rezvinhu zvakagadzirwa nesimende (simba rinogona kuwedzera ne20%-50% mukati memazuva 1-7). Izvi zvinoita kuti ive yakakodzera zvikuru kuvaka tembiricha yakaderera (senge kudira mvura munguva yechando) kana mapurojekiti ekugadzirisa emergency, zvichipfupisa nguva yekupisa uye kuona kuti simende inooma zvakanaka munzvimbo dzine tembiricha yakaderera, nokudaro zvichidzivirira kukuvara kwechando.
2. Kushanda Kwekongiri Kwakavandudzwa uye Kugara Kwenguva Refu
Mu simende, calcium formate inoderedza kubuda ropa nekupatsanurwa, zvichivandudza kubatana kwekongiri uye huwandu hwayo. Uyezve, mvura inogadzirwa inozadza maburi esimende, ichideredza maburi, zvichiita kuti simende isapinda mvura, isatsvedze chando, uye isatsvedze ngura, nokudaro ichiwedzera hupenyu hwebasa resimende.
3. Yakakodzera kushandiswa kwakasiyana-siyana kwezvigadzirwa zvesimende
Mukugadzirwa kwezvikamu zvakagadziriswa kare, zvakaita semapaneru nemapombi akagadziriswa kare, calcium formate inokurumidza kuchinja kwechimiro, inopfupisa nguva yekubvisa zvinhu, uye inovandudza kushanda zvakanaka kwekugadzira.
Shotcrete: Inoshandiswa mukuita basa rekupfapfaidza mumatunnel, migodhi, nemamwe mapurojekiti, inokurumidza kumira uye kuoma, ichideredza kurasikirwa kwemvura inodzoka uye ichivandudza kushanda zvakanaka kwekuvaka.
Zvinhu zvemadhaka nematombo: Zvinovandudza kuchengetedza mvura uye kusimba kwekutanga kwematombo, zvichiita kuti matombo afambire mberi nekukurumidza.
4. Zvakanakira Zvezvakatipoteredza uye Kuenderana
Mutengo weCalcium FormateHaina chepfu uye haitsamwisi, uye inoenderana nesimende, zvinhu zvinoderedza mvura, dota remhepo, nezvimwe zvinosanganiswa. Haikonzeri matambudziko akadai se alkali-aggregate reaction mukongiri, zvichizadzisa zvinodiwa nekugadzirwa kwezvinhu zvekuvaka zvakasvibira. Cherechedza: Chiyero che calcium formate chinofanira kudzorwa zvakasimba (kazhinji 1%-3% yehukuru hwesimende). Kuwedzera zvakanyanya kunogona kunonotsa kukura kwesimba rekongiri uye kutokonzera kupwanyika kwematombo. Kugadzirisa kunofanirwa kuitwa zvichienderana nezvinhu zvakaita senzvimbo yepurojekiti uye rudzi rwesimende.
