Calcium formate mugadziriAojin Chemical inogovera newe mashandisirwo ecalcium formate muindasitiri yekuvaka simende. Iyo calcium formate inotengeswa neAojin Chemical ine huwandu hwepamusoro hwe98% uye inoiswa mu25kg / bhegi.
Calcium formate inogadzira Aojin Chemical inogovera mashandisirwo ayo muindasitiri yekuvaka simende. Aojin Chemical inotengesa calcium formate ine yakakwira 98% yemukati, yakaiswa mumabhegi 25kg.
Calcium formate (Ca(HCOO) ₂), inoshanda zvakanyanya organic yekutanga-simba mumiriri, inoshandiswa mukugadzirwa kwekongiri uye simende zvigadzirwa nekuda kwekusiyana kwayo kwemakemikari zvimiro. Mabasa ayo ekutanga uye mashandisirwo ndeaya anotevera:
1. Simba Rekutanga uye Kuisa Kuwedzera
Calcium formate inomhanyisa zvakanyanya simende hydration, kunyanya iyo hydration ye tricalcium silicate (C₃S) uye tricalcium aluminate (C₃A). Izvi zvinokurumidzira kuumbwa uye kugadzika kwezvigadzirwa zve hydration (zvakadai se ettringite uye calcium hydroxide), nokudaro zvichivandudza simba rekutanga resimende-based materials (simba rinogona kuwedzera ne20% -50% mukati memazuva 1-7). Ichi chivakwa chinoita kuti chinyatsokodzera kudzika-tembiricha kuvaka (sekudururwa munguva yechando) kana mapurojekiti ekugadzirisa nekukurumidza, kupfupisa nguva yekurapa uye nekuona kuti kongiri inoomesa kazhinji munzvimbo dzakaderera-tembiricha, nokudaro kudzivirira kukuvara kwechando.
2. Yakavandudzwa Concrete Workability uye Durability
Mune simende paste, calcium formate inoderedza kubuda ropa uye kupatsanurwa, kuvandudza kongiri homogeneity uye density. Uyezve, zvigadzirwa zvayo zve hydration zvinozadza ma pores esimende paste, kuderedza porosity, zvisina kunanga kusimudzira kusamira kwekongiri, chando kuramba, uye kusagadzikana kwekuora, nekudaro vachiwedzera hupenyu hwesevhisi yezvigadzirwa zvesimende.
3. Inokodzera zvakasiyana-siyana zvesimende zvigadzirwa zvekushandisa
Mukugadzirwa kwechikamu cheprecast, senge precast mapaneru uye pombi mirwi, calcium formate inomhanyisa kushanduka kwe mold, inopfupisa nguva yekudhirowa, uye inovandudza kugadzirwa kwakanaka.
Shotcrete: Inoshandiswa mukupfapfaidza mabasa mumatani, mumigodhi, uye mamwe mapurojekiti, inokurumidza kuseta nekuomesa, ichideredza kurasikirwa kwekudzokera uye kuvandudza kugona kwekuvaka.
Zvigadzirwa zvedhaka uye masonry: Inovandudza kuchengetedza kwemvura uye simba rekutanga redhaka, kuve nechokwadi kufambira mberi nekukurumidza mumasonry uye kupurasita maitiro.
4. Zvakatipoteredza uye Kuenderana Zvakanakira
Calcium formate Mutengohaina chepfu uye haigumbure, uye inowirirana nesamende, zvinoderedza mvura, madota enhunzi, uye zvimwe zvinosanganisa. Izvo hazvikonzere matambudziko akadai sealkali-aggregate reaction mukongiri, kusangana nezvinodiwa zvegirinhi zvekuvaka zvinhu kuvandudzwa. Cherechedza: Iyo calcium formate dosage inofanira kunyatsodzorwa (kazhinji 1% -3% yehuremu hwesimende). Kuwedzera kuwedzera kunogona kuderedza kukura kwesimba rekongiri uye kutokonzera kutsemuka. Kugadziriswa kunofanirwa kuitwa zvichienderana nezvinhu zvakaita senzvimbo yeprojekiti uye rudzi rwesimende.
