Iyini i-Calcium sulfate dihydrate CAS 10101-41-4?

I-calcium sulfate dihydrate ibizwa nangokuthi "i-gypsum yemvelo engenamanzi". Ifomula yamakhemikhali i-CaSO4. Isisindo sama-molecule 136.14. Amakristalu e-Orthorhombic. Ubuningi obuhlobene 2.960, inkomba yokubuyisa 1.569, 1.575, 1.613. Enye i-gypsum engenamanzi encibilikayo: iphuzu lokuncibilika 1450℃, ubuningi obuhlobene 2.89, inkomba yokubuyisa 1.505, 1.548, iyabola lapho kushushu okumhlophe. I-hemihydrate yayo ivame ukwaziwa ngokuthi "i-gypsum eshisiwe" kanye ne-"platinum calciformis", ikakhulukazi ngesimo sempuphu emhlophe engeyona ikristalu, enobuningi obuhlobene obungu-2.75. I-dihydrate yayo ivame ukwaziwa ngokuthi "i-gypsum", okuyikristalu emhlophe noma impuphu, enobunzima obuhlobene obungu-2.32, inkomba yokubuyisa 1.521, 1.523, 1.530, futhi ilahlekelwa yiwo wonke amanzi ekristalu uma ishiswa ibe ngu-163℃. I-Chemicalbook Incibilika kancane emanzini, i-hydrochloric acid, i-nitric acid, incibilika ku-sulfuric acid eshisayo, ayincibiliki otshwaleni. Imikhiqizo yemvelo incibilika ku-alkaline sulfate, i-sodium thiosulfate, kanye nezixazululo zamanzi ze-ammonium salt. Indlela yokulungiselela: I-gypsum yemvelo engenamanzi itholakala ngokusabela i-CaO kanye ne-SO3 ngaphansi kokushisa okubomvu. I-gypsum encibilikayo engenamanzi itholakala ngokushisa i-CaSO4·2H2O ibe yisisindo esingaguquki ku-200℃. I-Hemihydrate itholakala ngokugaya nokukhipha amanzi ku-gypsum eluhlaza. I-Dihydrate itholakala ngokusabela i-calcium chloride ne-ammonium sulfate. Ukusetshenziswa okuyinhloko kwe-calcium sulfate: I-gypsum yemvelo engenamanzi isetshenziswa kakhulu kwezokwelapha; i-gypsum encibilikayo engenamanzi ingasetshenziswa njengomhlobiso wangaphakathi, futhi ingasetshenziswa futhi ekwenzeni amakhemikhali, iziphuzo, njll.; i-hemihydrate isetshenziswa kakhulu ezintweni zokwakha, futhi ingasetshenziswa futhi ekwenzeni izithombe ze-gypsum nezinto ze-ceramic; i-dihydrate yayo isetshenziselwa ukwenza i-hemihydrate, izigcwalisi, njll.

Isicelo

Ukusetshenziswa Kwezimboni

‌1. Isithibi sesikali: I-calcium sulfate dihydrate inamandla okuvimbela isikali futhi ingasetshenziswa ekuphatheni amanzi ezinhlelweni zezimboni ukuvimbela ukukhukhuleka ngaphakathi kwamapayipi nemishini nokugcina ukusebenza okuvamile kwesistimu.

‌2. Izinto zokusetshenziswa zezimboni: I-calcium sulfate dihydrate ingasetshenziswa njengezinto zokusetshenziswa ekulungiseleleni ezinye izinto zamakhemikhali, njenge-gypsum, ibhodi le-gypsum, i-gypsum powder, njll.

‌3. Izinto zokwakha: Embonini yokwakha, i-calcium sulfate dihydrate ingasetshenziswa njengomkhiqizo we-gypsum ezintweni zokwakha zokuhlobisa nokulungisa izindonga, ophahleni, njll.

‌4. I-ejenti yokucubungula imayini: Ekucubungulweni kwemayini, i-calcium sulfate dihydrate ingasetshenziswa njenge-ejenti eyisizayo enqubweni yokuntanta nokuhlanzwa ukuze kukhuthazwe ukuhlukaniswa nokuhlanzwa kwama-ore.

Ukusetshenziswa Kwezolimo

‌1. Isilungisi somhlabathi: I-calcium sulfate dihydrate ingalungisa i-pH yenhlabathi, ithuthukise isakhiwo somhlabathi, ikhulise ukuvunda kwenhlabathi, futhi ikhuthaze ukukhula kwezitshalo.

‌2. Isithasiselo sokudla: Njengomthombo we-calcium, i-calcium sulfate dihydrate inganezela isakhi se-calcium ezilwaneni futhi ikhuthaze ukukhula kwezilwane kanye nokuthuthukiswa kwamathambo.

‌3. Izinto zokusetshenziswa kwezibulala-zinambuzane: Kwezolimo, i-calcium sulfate dihydrate ingasetshenziswa njengezinto zokusetshenziswa kwezibulala-zinambuzane, ukulungiselela izibulala-zinambuzane, izibulala-fungi, njll.

Ukusetshenziswa kwezokwelapha

‌1. Izinto zokusetshenziswa kwemithi: I-calcium sulfate dihydrate ingasetshenziswa njengezinto zokusetshenziswa kwemithi zokulungiselela izithasiselo ze-calcium, ama-antacid kanye neminye imithi yokwelapha i-osteoporosis, i-hyperacidity kanye nezinye izifo.

‌2. Izinto zokwelapha: Ivame ukusetshenziselwa ukwenza amabhandeji e-plaster ukuze kuqiniswe ukuphuka. I-plasticity enhle kanye nokuqina okuhle futhi iyasiza ekwelapheni ukuphuka.
