Umthengisi weCalcium Chloride Dihydrate eMzantsi Afrika

Yintoni iCalcium Chloride Dihydrate?

I-calcium chloride dihydrate (CaCl₂·2H₂O) yindlela enyibilikisiweyo ye-calcium chloride — iigranule ezimhlophe, iiprills, okanye iiflakes ezithambileyo kakhulu (zifunxa umswakama emoyeni) kwaye zinyibilika kakhulu emanzini. Ukunyibilika kushushu kakhulu. I-calcium chloride yeyona mithombo ifumaneka lula kwaye ingabizi kakhulu ye-soluble calcium ions (Ca²⁺) yonyango lwamanzi, ubuchwepheshe bekhonkrithi, ukucubungula amashishini, kunye nokusetyenziswa kwezolimo. Uhlobo lwe-dihydrate (74–77% CaCl₂ elinganayo) lolona didi luqhelekileyo lorhwebo — uhlobo lwe-anhydrous (94–97% CaCl₂) kunye ne-77% flake nazo ziyafumaneka. I-Terracore Chemicals inikezela ngodidi lwe-dihydrate kwiingxowa ezingama-25 kg kunye ne-1 MT kuMzantsi Afrika.

Unyango lwamanzi kunye nohlengahlengiso lobunzima

Kwindlela yokunyanga amanzi, i-calcium chloride isetyenziselwa ukwandisa ubunzima be-calcium emanzini asebenzayo, amachibi okudada, iinqaba zokupholisa, kunye neenkqubo zamanzi okusela. Ubunzima be-calcium echibini lokudada (ithagethi: 200–400 mg/L njengeCaCO₃) kufuneka bugcinwe ukuze kuthintelwe amanzi echibini ukuba anganyibilikisi i-calcium kwi-plaster okanye kwiindawo zedama zekhonkrithi (amanzi ane-calcium ephantsi "enamandla"). Kumanzi okusela aphinda anyibilike - emva kokuba i-osmosis ebuyela umva okanye ukuthamba kwelayimu kususa i-calcium - i-calcium chloride yongezwa kunye ne-sodium bicarbonate ukubuyisela i-Langelier Saturation Index (LSI) kunye nokuthintela ukugqwala kwemibhobho yokusasazwa. Kwiinkqubo zamanzi okuphola, ubunzima be-calcium bugcinwa ukulawula ukuthambekela kokukala kwe-calcium carbonate kunye nokulinganisela i-chemistry yokuthintela ukugqwala. I-calcium chloride ikwasetyenziswa njengoncedo lwe-flocculant kunye ne-polyelectrolytes.

Ukukhawuleziswa kwekhonkrithi kunye nezinye izicelo zemizi-mveliso

Kwiteknoloji yekhonkrithi, i-calcium chloride isetyenziswa njengomxube okhawulezayo - ikhawulezisa ukufuma kwesamente yasePortland, inyusa ukwanda kwamandla kwangoko (amandla oxinzelelo lweeyure ezingama-24 kunye neentsuku ezi-3). Umthamo oqhelekileyo: 1–2% CaCl₂ ngobunzima besamente. Isetyenziswa kwikhonkrithi yemozulu ebandayo nakwimveliso yekhonkrithi elungisiweyo. Qaphela: I-accelerator ye-CaCl₂ ayisetyenziswa kwikhonkrithi eqinisiweyo okanye kwikhonkrithi exineneyo, njengoko i-chloride ikhawulezisa ukubola kokuqina. Ekucinezeleni uthuli kwiindlela zegrabile nakwiindlela zokuthutha imigodi, isisombululo se-calcium chloride siyatshizwa ukuze kufunxwe umswakama womoya kwaye sibophe amaqhekeza endlela, sinciphise uthuli. Ekulungisweni kokutya, i-calcium chloride isetyenziswa kwimveliso yetshizi (ukubuyisela i-calcium elahlekileyo ngexesha lokucoca), kwimveliso ye-pickle kunye ne-brine, kwaye njenge-arhente yokuqinisa. I-Terracore Chemicals inikezela nge-calcium chloride dihydrate yenqanaba lokutya kunye nenqanaba lobuchwephesha.
