Calcium sulfate hemihydrate CAS 10034-76-1
Calcium sulfate inonziwo mbishi gypsum, gypsum yakaoma mbishi, Muriacite, gypsum isina mvura. Makristasi asina ruvara orthorhombic (rudzi rweβ) kana makristaro emonoclinic (rudzi rweα). Kurema kwemamorekuru 136.14. Kuwanda kwemakemikari 2.960. Nzvimbo yekunyunguduka 1193℃ (inoshandurwa kubva kurudzi rweβ kuenda kurudzi rweα), 1450℃ (rudzi rweα, uye yakaora). Inonyunguduka zvishoma mumvura (0.209 pa20℃), inonyunguduka muacid, munyu weammonium, sodium thiosulfate, sodium chloride solution uye glycerol. Kunyangwe mvura ikawedzerwa, haichagoni kuva calcium sulfate dihydrate. Kana gypsum ore yechisikigo yakashaikwa mvura zvachose pasi pe300℃, gypsum inonyunguduka inonyunguduka mumvura inogona kugadzirwa; kana gypsum yechisikigo ikapiswa kusvika pamusoro pe600℃, gypsum isina mvura inonyunguduka inogadzirwa. Kana calcium sulfate kana plaster yeParis yakasanganiswa nemvura yakakwana, inooma zvishoma nezvishoma. Inoshandiswa semushonga unodzivisa kupisa, unonamira, unonwisa hunyoro, unopolisha upfu, unozadza mapepa, unobvisa gasi, unosunga plaster, uye unogadzirwa nemaoko. Gypsum inoshandiswa sezvinhu zvekugadzira simende, uye inogona kugadzirisa nguva yekuisa simende. Inoshandiswa semushonga unopwanya mvura mukugadzira tofu, yeast feed, muchina wekugadzirisa dough, uye muchelating agent. Kune migodhi yegypsum yechisikigo, uye zvimwe zvigadzirwa zveindasitiri yephosphate zvine calcium sulfate. Mushonga weammonium sulfate unosangana ne calcium chloride solution, uye kupfapfaidza, kushambidza uye kunaya kwemvura zvinogona kugadzira chigadzirwa chakachena.

Kugadziriswa kwechikafu:
Calcium sulfate inogona kushandiswa semushonga wekurapa hupfu (semushonga wekubvisa benzoyl peroxide), nekushandiswa kwakanyanya kwe1.5 gramu pa kilogiramu; inoshandiswa semushonga wekubatanidza chikafu. Inoshandiswa kugadzira tofu, uye magiramu angangoita 14-20 pa litre yesoya anowedzerwa mumukaka wesoya (huwandu hwakawanda hunokonzera kuvava). Inowedzerwa muhupfu hwegorosi pa0.15% uye inoshandiswa seyeast food and dough regulator. Inowedzerwa kumadomasi nembatatisi sekusimbisa tissue. Inoshandiswa semushonga wekusimbisa mvura uye mukuwedzera kunaka pakubika doro. Inogona zvakare kushandiswa sekuwedzera kwekudya.
Kugadzirwa kwemaindasitiri:
1. Indasitiri yekuvaka: Calcium sulfate inogona kushandiswa muindasitiri yekuvaka zvinhu zvekuvaka, zvinhu zvinodzivirira kupisa, machira, zvinhu zvinosimbisa, nezvimwewo. Mashava eCalcium sulfate ane kukweshana kwakanaka, kuchengetedza kupisa, kudziya, kudzivirira moto, kudziya kusingakonzeresi nezvimwe zvinhu, uye anogona kutsiva asbestos sechinhu chinokwesha, chinhu chinodzivirira kupisa, uye chinhu chinodzivirira moto (chinodzivirira moto). Inoshandiswa sechinhu chinosimbisa simba rekutanga mumasanganiswa ekongiri, kazhinji ine dosi inosvika 3%, kugadzirisa nguva yekugadzika uye kusanganisa nesimende. Kana calcium sulfate ikaiswa mukongiri, ine simba guru rekutanga.
2. Indasitiri yekugadzira mapepa: Calcium sulfate inoshandiswa muindasitiri yekugadzira mapepa kutsiva chikamu kana chikamu chikuru chepulp. Calcium sulfate ine aspect ratio iri pasi kana yakaenzana ne50 inogona kushandiswa semuchina wekuzadza mapepa wepamusoro, izvo zvinogona kuwedzera kugadzirwa kwepepa, kuderedza kushandiswa kwehuni, uye kubatsira kuchengetedza nharaunda uye kuderedza kusvibiswa kwemvura yakasviba.
3. Indasitiri yemakemikari: Muindasitiri yemakemikari, inogona kushandiswa sechinhu chinosimbisa. Mashave ecalcium sulfate ane mvura anogona kushandiswa mupurasitiki kuti awedzere simba rezvidimbu zvepurasitiki, arambe achidzivirira kupisa kwakanyanya, uye aderedze mitengo. Mukugadzira mapurasitiki akadai sepolyvinyl chloride, polyethylene, propylene, uye polystyrene, inogona kuwedzera mashandiro ezvikamu zvakasiyana zvechigadzirwa, kuvandudza kupfava, kugadzikana kwemativi, kupedzisa kwepazasi, simba rekudhonza, simba rekukotama, kukotama kwe elastic modulus uye tembiricha yekupisa, uye kuderedza kupfeka kwemidziyo. Semuzadzisi weasphalt, inogona kuwedzera zvakanyanya nzvimbo yekunyorovesa yeasphalt.
Kurima:
Calcium sulfate inogona kushandiswa sefetereza mukurima kuderedza alkalinity yevhu uye kuvandudza mashandiro evhu.
Mushonga:
Calcium sulfate ine mashandisirwo akasiyana-siyana muindasitiri yemishonga. Inogona kushandiswa kugadzira mishonga uye kupa zvinhu zvinodiwa uye hunhu hwemishonga. Pamusoro pezvo, calcium sulfate inoshandiswawo kugadzira mapiritsi kuti ive nechokwadi chekuti mapiritsi akasimba uye anoshanda. Panguva imwe chete, inowedzerwawo mutoothpaste kuti iwedzere kuumbwa uye kushanda kwetoothpaste. Mashandisirwo aya anoratidza kukosha kwecalcium sulfate muindasitiri yemishonga, ichipa zvinhu zvakakosha uye hunhu hwezvigadzirwa zvemishonga.
