Calcium sulfate dihydrate CAS 10101-41-4
Calcium sulfate dihydrate imatchedwanso "natural anhydrous gypsum". Chemical formula CaSO4. Kulemera kwa molekyulu 136.14. Makristasi a Orthorhombic. Kachulukidwe wachibale 2.960, refractive index 1.569, 1.575, 1.613. gypsum ina yosungunuka ya anhydrous: malo osungunuka 1450 ℃, kachulukidwe wachibale 2.89, refractive index 1.505, 1.548, amawola poyera kutentha. Hemihydrate yake imadziwika kuti "gypsum yoyaka" ndi "platinamu calciformis", makamaka mu mawonekedwe a ufa woyera wopanda crystalline, wokhala ndi kachulukidwe ka 2.75. Dihydrate yake imadziwika kuti "gypsum", yomwe ndi kristalo woyera kapena ufa, wokhala ndi kachulukidwe ka 2.32, refractive index 1.521, 1.523, 1.530, ndipo amataya madzi onse akristalo akatenthedwa mpaka 163 ℃. Chemicalbook Amasungunuka pang'ono m'madzi, hydrochloric acid, nitric acid, sungunuka mu hot sulfuric acid, osasungunuka mu mowa. Zinthu zachilengedwe zimasungunuka mu alkaline sulfate, sodium thiosulfate, ndi ammonium salt aqueous solutions. Kukonzekera njira: Natural anhydrous gypsum imapezeka pochita CaO ndi SO3 pansi pa kutentha kofiira. gypsum sungunuka anhydrous ndi akamagwira Kutentha CaSO4 · 2H2O kwa kulemera zonse pa 200 ℃. Hemihydrate amapezedwa ndi calcining ndi dehydrating yaiwisi gypsum. Dihydrate imapezeka pochita calcium chloride ndi ammonium sulfate. Ntchito zazikulu za calcium sulfate: Natural anhydrous gypsum imagwiritsidwa ntchito kwambiri pamankhwala; gypsum wosungunuka wa anhydrous angagwiritsidwe ntchito ngati zokongoletsera zamkati, komanso angagwiritsidwe ntchito kupanga mankhwala, zakumwa, ndi zina; hemihydrate imagwiritsidwa ntchito kwambiri pomanga, komanso ingagwiritsidwe ntchito popanga ziboliboli za gypsum ndi zida za ceramic; dihydrate ake amagwiritsidwa ntchito kupanga hemihydrate, fillers, etc.

Zogwiritsa Ntchito Zamakampani
1. Scale inhibitor: Calcium sulfate dihydrate ili ndi ntchito yabwino yoletsa ndipo imatha kugwiritsidwa ntchito pochiza madzi m'mafakitale kuti apewe kukulitsa mipope ndi zida ndikusunga magwiridwe antchito adongosolo.
2. Industrial zopangira: Calcium sulfate dihydrate angagwiritsidwe ntchito ngati zopangira pokonzekera zinthu zina mankhwala, monga gypsum, gypsum board, gypsum ufa, etc.
3. Zipangizo zomangira: M'makampani omanga, calcium sulfate dihydrate ingagwiritsidwe ntchito ngati gypsum mankhwala muzomangamanga zokongoletsa ndi kukonza makoma, kudenga, etc.
4. Migodi processing wothandizira: Pokonza migodi, kashiamu sulfate dihydrate angagwiritsidwe ntchito ngati wothandizira wothandiza mu flotation ndi kuyeretsa ndondomeko kulimbikitsa kulekana ndi kuyeretsa ores.
Ntchito Zaulimi
1. Chotenthetsera nthaka: Calcium sulfate dihydrate imatha kusintha pH ya nthaka, kukonza dothi, kuwonjezera chonde m'nthaka, ndikulimbikitsa kukula kwa mbewu.
2. Chowonjezera cha chakudya: Monga gwero la calcium, calcium sulfate dihydrate imatha kuwonjezera kashiamu mu nyama ndikulimbikitsa kukula kwa nyama ndi kukula kwa mafupa.
3. Zida zopangira mankhwala: Paulimi, calcium sulfate dihydrate ingagwiritsidwe ntchito ngati zopangira mankhwala ophera tizilombo, pokonzekera mankhwala ophera tizirombo, fungicides, etc.
Ntchito zamankhwala
1. Mankhwala zopangira: Calcium sulfate dihydrate angagwiritsidwe ntchito ngati mankhwala zopangira pokonza kashiamu zowonjezera mavitamini, maantacid okhala ndi mankhwala ena kuchiza osteoporosis, hyperacidity ndi matenda ena.
2. Zipangizo zachipatala: Nthawi zambiri amagwiritsidwa ntchito popanga mabandeji a pulasitala kuti athe kung'ambika. Zili ndi pulasitiki yabwino komanso yokhazikika komanso zimathandiza kuchiritsa kwa fractures.
3. Zipangizo zamano: M'munda wamano, calcium sulfate dihydrate itha kugwiritsidwa ntchito kupanga nkhungu zamano ndi zodzaza.
4. Zovala pabala: Zimakhala ndi mayamwidwe ena amadzi komanso mpweya ndipo zimatha kugwiritsidwa ntchito pomanga mabala ena.
Kugwiritsa ntchito zakudya
1. Zakudya zowonjezera: Calcium sulfate dihydrate imatha kusintha pH ya chakudya, kuonjezera kuuma ndi kukoma kwa chakudya, ndikuchita nawo ngati coagulant pakupanga zakudya monga tofu.
2. Zotetezera: Zimagwiritsidwa ntchito posungirako chakudya, zakumwa, ndi zina kuti ziwonjezere moyo wa alumali wa chakudya.
