Calcium Chloride Mugadziri
Nhanganyaya
Calcium chloride isanganiswa ine kemikari formula CaCl2.
Chemical Properties:
Calcium chloride munyu unoumbwa ne calcium uye chlorine ions. Inonyungudika zvakanyanya mumvura uye ine chitarisiko chichena.
Mhinduro:CaCO3 + 2HCl => CaCl2 Calcium chloride + H2O + CO2
Calcium chloride yakanyanya hygroscopic, yakanyanya kuderera, uye inogona kunyungudika nyore mumvura.
Kana yanyungudutswa mumvura, inogadzira huwandu hukuru hwekupisa kwemhinduro uye inodzikisa zvakanyanya nzvimbo yekutonhora yemvura, ine yakasimba anti-chando uye de-icing mhedzisiro.
Industrial Applications
Deicing uye Anti-Icing:
Imwe yeanonyanya kushandiswa yecalcium chloride iri mu deicing uye anti-icing mhinduro. Chimiro chayo chehygroscopic chinoibvumira kukwezva hunyoro kubva kumhepo, kudzikisa nzvimbo yekutonhora kwemvura uye kudzivirira kuumbwa kweaizi mumigwagwa, mumigwagwa, uye nzira dzekumhanya. Calcium chloride inosarudzwa pakuita deicing nekuda kwekushanda kwayo kunyangwe pakadzika tembiricha kana ichienzaniswa nemamwe maajenti e deicing.
Kudzora Dust:
Calcium chloride inoshandiswa zvakanyanya kudzvinyirira guruva mumigwagwa, nzvimbo dzekuvaka, uye mabasa emigodhi. Kana yaiswa panzvimbo isina kugadzirwa, inotora hunyoro kubva mumhepo nepasi, ichidzivirira kuumbwa kweguruva. Izvi hazvisi kungovandudza kuonekwa uye hutano hwemhepo asiwo zvinoderedza mari yekugadzirisa inobatanidza nekutonga kweguruva.
Concrete Acceleration:
Muindasitiri yekuvaka, calcium chloride inoshandiswa sekongiri accelerator, ichimhanyisa kuseta uye kuomesa maitiro ekongiri. Nekuwedzera chiyero che hydration, inobvumira kukurumidza kuvaka nguva uye inoita kuti basa rienderere mberi kunyangwe mukutonhora kunotonhora, uko kwechinyakare kongiri marongero anogona kunonoka.
Kugadzira Chikafu:
Mukugadzira chikafu, calcium chloride inowana kushandiswa sechinhu chinosimbisa, kuchengetedza, uye kuwedzera. Inosimudzira kunaka uye kusimba kwezvakasiyana siyana zvekudya zvakaita semichero yemumagaba nemiriwo, tofu, nemagaka. Pamusoro pezvo, calcium chloride inoshandiswa mukugadzira chizi kusimudzira coagulation nekuvandudza goho.
Desiccation:
Calcium chloride inoshanda se desiccant mune dzakasiyana siyana maindasitiri maitiro uko kudzora mwando kwakakosha. Inoshandiswa mukuomeswa kwegasi kubvisa mhute yemvura kubva kumagasi uye kuchengetedza kushanda kwemidziyo yakaita sefiriji masisitimu, maair conditioning units, uye compressed air systems.
Kuchera Oiri neGasi:
Muindasitiri yeoiri negasi, calcium chloride inoita basa rakakosha mukuchera matsime uye kupedza mabasa. Inoshandiswa sekuwedzera kwemvura yekuchera kudzora viscosity, inhibit ivhu kuzvimba, uye kuchengetedza kugadzikana kwetsime. Calcium chloride brines inoshandiswawo mu hydraulic fracturing (fracking) kuwedzera kupora kwemvura uye kudzivirira kukanganisa kuumbwa.
Kuchengeta Kupisa:
Pamusoro peiyo hygroscopic hunhu, calcium chloride inoratidza exothermic zvimiro kana yakanyungudutswa mumvura, saka hydrated munyu CaCl2 chinhu chinovimbisa chepasi-giredhi thermochemical kupisa kwekuchengetedza.
