K'halsiamo sulfate. tlhaloso

Ea Kajeno Inorganic k'hemistri bohlokoa haholo letsoai tlhophiso le thepa ea likarolo sebelisana le metsoako eohle ea bona ho ka khonehang. Ho na le dintho hore, har'a ba bang lula sebakeng se khethehileng. metsoako joalo ka ho khetheha ba lokela ho ho fetisetswa k'halsiamo sulfate. Moralo ntho CaSO4.

mobung batlang e le e khōlō ea motsoako ona ka karolong e ka holimo le lumella tšebeliso lona le boitsebiso bo sa e tala ka ba lokisetsa ho ea thepa e fapaneng. Thepa sephetho le ka ka katleho a sebelisa ho kaho, meriana le libakeng tse ling.

fumanwa mobung matsoai ho ba le ho hlophisoa ha CaSO4 2 H2O Ka maemo a tlhaho. K'halsiamo sulfate e hape fumanoang ka leoatle (ka 1800 000 tonnes ka mitha dikhubu) le metsi a hloekileng.

CaSO4 anhydride ke tšoeu phofo segokanyipalo sa dikgerama 2.90-2.99 ka disentimitara dikhubu. Komponeng mafolofolo monyang mongobo ho tloha moeeng. Ka lebaka la thepa ena, 'me k'halsiamo sulfate sebelisoa e le omisa moemeli.

Ha thempereichara e likete tse makholo a mane a mashome a mahlano qhibiliha likhato ntho le bola. The solubility tsa ntho e ntlafatsoa ka ho ba teng ha HCl, HNO3, NaCl, MgCl2. K'halsiamo sulfate a leka ho le asiti sulfuric e fokotsehile ha sintering le k'habone.

Ho ba ka metsing hammoho MgSO4 le MgCl2, CaSO4 tenyetsehe fana e le kamehla. Lik'hemik'hale softening mokelikeli ke khoneha ho reagents ena. Phokotso ea thatafala ya metsi e thehiloeng ho qaloa ho dintho ntlafatsa anions lona.

Softening ea metsi e boetse e etsoa ka ho phapanyetsano Ion. Mokhoa ona o thehiloe bokhoni ba itseng phapanyetsano maiketsetso le tsa tlhaho Ion - metsoako phahameng-limolek'hule - fapanyetsana radicals kenyelelitsoe sebopeho bona, ka ions teng tharollo. Ka Ion phapanyetsano hangata e sebetsa aluminosilicates (Na2 [Al2Si2O8] ∙ nH2O, ho etsa mohlala).

Hydrate le ea ho hlophisoa 2CaSO4 H2O - Alabaster (chesa gypsum) - le sebelisitsoe ka tlhahisong ea thepa cementitious. dintho tsena emela metsoako pulverulent, eo ha tsoakane le diforomo tsa metsi polasetiki pele, 'me hamorao o ile a tiisa puso e be boima tiileng mmuso. Ho lokisetsa thulaganyou e e etsoa alabaster gypsum calcination tlas'a tšusumetso ea mocheso ho tloha mashome a mahlano lekholo ho likhato lekholo mashome a supileng. thepa ena e sebelisitsoeng ka eona ka tlhahisong ea diphanele arola le mapolanka, hlobo lintho, hammoho le ho kenya tshebetsong lila mohaho.

Calcination tlas'a tšusumetso ea mocheso likhato tse fetang tse makholo a mabeli ho lebisa hore ho thehoe sebōpeho qhibilihang ka har'a ya khalsiamo sulfate anhydrous, ka mocheso likhato khōlō ho feta tse makholo a mahlano - insoluble foromo. Ea bobeli ea lahleheloang matla a ho hokela metsi hoo, a ke ke a sebelisoa e le binder le.

Natural gypsum ka sebelisoa ka tshimololang boitsebiso bo ba lokisetsa ho ea samente le asiti sulfuric ke mokhoa oa ho kopantswe.

Natural k'halsiamo sulphate le ka boela sebelisoa e le desiccant ka ho hlahloba metsoako manyolo. The komponeng anhydrous ke khona ho monya mongobo 6.6 motho aka fihlella% ea boima ba 'mele palo yohle. K'halsiamo sulfate le boetse le sebelisoa ka tlhahisong ea thepa li sireletsang serameng.
