Calcium sulfate hemihydrate CAS 10034-76-1
I-calcium sulfate ibizwa nangokuthi i-gypsum eluhlaza, i-gypsum eluhlaza eqinile, i-Muriacite, i-anhydrous gypsum. Amakristalu angenambala we-orthorhombic (uhlobo lwe-β) noma amakristalu e-monoclinic (uhlobo α). Isisindo samangqamuzana esihlobene 136.14. Ukuminyana okuhlobene 2.960. Iphoyinti lokuncibilika 1193℃ (liguquliwe lisuka kuhlobo luka-β laya ohlotsheni α), 1450℃ (uhlobo α, futhi lonakele). Incibilika kancane emanzini (0.209 at 20℃), inyibilika ku-asidi, usawoti we-ammonium, i-sodium thiosulfate, isixazululo se-sodium chloride ne-glycerol. Ngisho noma amanzi engezwa, angeke esakwazi ukuba yi-calcium sulfate dihydrate. Uma i-gypsum ore yemvelo iphelelwe amanzi ngokuphelele ngaphansi kuka-300 ℃, i-gypsum encibilikayo e-anhydrous encibilikayo emanzini ingakhiqizwa; uma i-gypsum yemvelo ishisiswe ibe ngaphezu kuka-600 ℃, i-insoluble anhydrous gypsum iyakhiqizwa. Lapho i-anhydrous calcium sulfate noma ukhonkolo waseParis kuhlanganiswa nenani elifanele lamanzi, kancane kancane iyaqina. Isetshenziswa njenge-retarder, i-adhesive, imunca umswakama, impushana yokupholisha, ukugcwaliswa kwephepha, i-gas desiccant, ibhande le-plaster, kanye nomsebenzi wezandla. I-Gypsum isetshenziswa njengento eluhlaza ekwenzeni usimende, futhi ingakwazi ukulungisa isikhathi sokumisa usimende. Isetshenziswa njenge-coagulant ekwenzeni i-tofu, i-yeast feed, isilawuli senhlama, kanye ne-chelating agent. Kukhona izimayini ze-gypsum zemvelo, futhi imikhiqizo ephuma embonini ye-phosphate iqukethe i-calcium sulfate. Isixazululo se-ammonium sulfate sihlangana nesisombululo se-calcium chloride, futhi ukuhlunga, ukuwasha kanye nemvula kungaveza umkhiqizo ohlanzekile.

Ukucubungula ukudla:
I-calcium sulfate ingasetshenziswa njenge-ejenti yokwelapha ufulawa (njenge-diluent ye-benzoyl peroxide), ngokusetshenziswa okuphezulu kwamagremu angu-1.5 ikhilogremu ngayinye; isetshenziswa njenge-coagulant ekucubunguleni ukudla. Isetshenziselwa ukwenza i-tofu, futhi cishe amagremu angu-14-20 ilitha likabhontshisi wesoya yengezwa obisini lwesoya (inani eliningi lizoveza ukubaba). Yengezwa kufulawa kakolweni ngo-0.15% futhi isetshenziswe njengomlawuli wokudla imvubelo kanye nenhlama. Yengezwa kumatamatisi namazambane asemathinini njengendlela yokuqinisa izicubu. Isetshenziswa njengesiqinisi samanzi kanye nesithuthukisi ukunambitheka kokwenza ubhiya. Ingasetshenziswa futhi njengesengezo sokudla okunomsoco.
Ukukhiqizwa kwezimboni:
1. Imboni yezokwakha: I-calcium sulfate ingasetshenziswa embonini yokwakha izinto zokwakha, izinto zokufaka ezishisayo, okokugqoka, izinto zokuqinisa, njll. Amadevu e-calcium sulfate anokungqubuzana okuhle, ukugcinwa kokushisa, ukufakwa kokushisa, ukuvimbela umlilo, ukufakwa kwe-non-conductor nezinye izakhiwo, futhi kungangena esikhundleni se-asbestos njengento yokungqubuzana (i-fireproof) kanye ne-fireproof. Isetshenziswa njenge-ejenti yokuqala yamandla ezixubeni zikakhonkolo, ngokuvamile ezinomthamo ongaba ngu-3%, ukulungisa isikhathi sokumisa nokuxuba nokugaya usimende. Lapho i-calcium sulfate yengezwa kukhonkolo, inomphumela wamandla wangaphambi kwesikhathi obalulekile.
2. Imboni yokwenza amaphepha: I-calcium sulfate isetshenziswa embonini yokwenza iphepha ukuze ithathele ingxenye noma ingxenye enkulu ye-pulp. I-calcium sulfate ene-aspect ratio engaphansi noma elingana no-50 ingasetshenziswa njengesigcwalisi esisezingeni eliphezulu sephepha, esingakhuphula kakhulu ukukhiqizwa kwephepha, sinciphise ukusetshenziswa kwezinkuni, futhi sisize ukuvikela imvelo nokunciphisa ukungcoliswa kwamanzi angcolile.
3. Imboni yamakhemikhali: Embonini yamakhemikhali, ingasetshenziswa njengento yokuqinisa. Amadevu e-calcium sulfate anhydrous angasetshenziswa ku-granulation yepulasitiki ukuze kuthuthukiswe amandla ezinhlayiya zepulasitiki, ukumelana nokushisa okuphezulu, nokunciphisa izindleko. Ekukhiqizeni amapulasitiki afana ne-polyvinyl chloride, i-polyethylene, i-propylene, ne-polystyrene, ingathuthukisa ukusebenza kwezici ezihlukahlukene zomkhiqizo, ithuthukise ukucoleka, ukuqina kwe-dimensional, isiphetho esiphezulu, amandla aqinile, amandla okugoba, ukugoba i-elastic modulus kanye nezinga lokushisa lokushintsha okushisayo, nokunciphisa ukugqokwa kwemishini. Njengokugcwalisa i-asphalt, ingakhuphula kakhulu indawo yokuthambisa ye-asphalt.
Ezolimo:
I-calcium sulfate ingasetshenziswa njengomanyolo kwezolimo ukunciphisa u-alkalinity enhlabathini nokwenza ngcono ukusebenza kwenhlabathi.
Umuthi:
I-Calcium sulfate inezinhlobo ezahlukene zezicelo embonini yezemithi. Ingasetshenziselwa ukulungisa izidakamizwa futhi inikeze izithako ezidingekayo kanye nezakhiwo zezidakamizwa. Ngaphezu kwalokho, i-calcium sulfate isetshenziselwa ukwenza amaphilisi ukuqinisekisa ukuzinza nokusebenza kahle kwamaphilisi. Ngesikhathi esifanayo, iphinde yengezwe ku-toothpaste ukuze kuthuthukiswe ukubunjwa nokusebenza kwe-toothpaste. Lezi zicelo zibonisa ukubaluleka kwe-calcium sulfate embonini yezemithi, ehlinzeka ngezithako ezibalulekile kanye nezakhiwo zemikhiqizo yemithi.
