njira zopangira calcium chloride

Pali njira ziwiri zopangira kashiamu kolorayidi, imodzi ndi njira ya asidi ndipo ina ndi njira ya alkali.

Njira ya asidi imakonzedwa makamaka ndi mankhwala a miyala yamchere ndi hydrochloric acid. Pafupifupi 22% ya dilute hydrochloric acid imagwiritsidwa ntchito pochita ndi miyala yamchere (yokhala ndi pafupifupi 52% ya calcium) kuti ipange 27% yamadzimadzi a calcium chloride. Pambuyo kusefera ndi kulekanitsidwa, zotsalira za fyuluta zimatayidwa. The filtrate ndi neutralized ndi mkaka laimu kusintha pH = 8.9-9. Zowonongeka mu njira ya calcium chloride monga ine, Fe, al1, ndi zina zotero zimapanga osasungunuka ine (OH) 2, Fe (OH) 3, A1 (OH) 3, etc. Keke ya fyuluta ndi zinyalala zolimba, Sefayi imayendetsedwa ndi mphamvu zitatu zomwe zimakakamizidwa kutulutsa mpweya wa vacuum kuti zikhazikike 27% ya calcium chloride solution mpaka 68-69%, ndiyeno imadyetsedwa mu flaker kuti ipangidwe. Flake calcium chloride imawuma pabedi lamadzimadzi kuti ipange 74% calcium chloride dihydrate.

Njira ya alkali imatulutsa calcium chloride: 1. Njira ya kashiamu kolorayidi ya evaporation: nthawi zambiri, calcium chloride yomwe ili muzakumwa zotayidwa za soda ndi 76.8g/l. Pambuyo pa kuyeretsedwa, choyamba chimayikidwa, kulekanitsidwa ndi makhiristo opanda pake, kenaka amaikapo kuti apeze calcium chloride.

2. Calcium chloride salt field pre evaporation process: Nthawi zambiri, kufalikira kwa mchere kumagwiritsidwa ntchito kusungunula zinyalala za soda. Mchere mumadzi otayira umakhazikika, ndipo mchere womwe uli mumadzi otayira umayamba kugwa. Ndi kuwonjezeka kwa evaporation, mchere wochuluka udzasungunuka. Madzi otsala a calcium chloride adzasonkhanitsidwa m'zida za nthunzi, ndipo calcium chloride idzapezeka.

Kusiyanitsa pakati pa njira ziwiri zopangira ndikuti kuuma kwa calcium chloride yopangidwa ndi njira ya asidi ndipamwamba kuposa njira ya alkali, koma pali zonyansa zambiri, mtundu wosakhazikika ndi kukoma, ndipo njira ya asidi ndi yotsika mtengo kuposa njira ya alkali. Mapiritsi a calcium chloride omwe amapezedwa ndi njira ya alkali ndi yoonda komanso osalimba, oyera kwambiri, zonyansa zochepa komanso zoyera kwambiri.
