Iyini i-Calcium sulfate hemihydrate CAS 10034-76-1?

I-calcium sulfate ibizwa nangokuthi i-raw gypsum, i-hard raw gypsum, i-Muriacite, i-anhydrous gypsum. Amakristalu e-orthorhombic angenambala (uhlobo lwe-β) noma amakristalu e-monoclinic (uhlobo lwe-α). Isisindo sama-molecule esihlobene 136.14. Ubuningi obuhlobene 2.960. Iphuzu lokuncibilika 1193℃ (liguqulwa kusuka kuhlobo lwe-β liye kuhlobo lwe-α), 1450℃ (uhlobo lwe-α, futhi libolile). Lincibilika kancane emanzini (0.209 ku-20℃), lincibilika ku-asidi, usawoti we-ammonium, i-sodium thiosulfate, isisombululo se-sodium chloride kanye ne-glycerol. Ngisho noma amanzi engeziwe, awasakwazi ukuba yi-calcium sulfate dihydrate. Uma i-gypsum ore yemvelo incibilika ngokuphelele ngaphansi kwama-300℃, i-gypsum anhydrous encibilikayo encibilika emanzini ingakhiqizwa; uma i-gypsum yemvelo ishiswa ibe ngaphezu kwama-600℃, kukhiqizwa i-gypsum anhydrous engancibiliki. Lapho i-calcium sulfate noma i-plaster yaseParis ixutshwa nenani elifanele lamanzi, iqina kancane kancane. Isetshenziswa njenge-retarder, i-glue, i-moving umswakama, i-polishing powder, i-paper filling, i-gas desiccant, i-plaster bandage, kanye ne-handicraft. I-Gypsum isetshenziswa njengezinto zokusetshenziswa zokwenza usimende, futhi ingalungisa isikhathi sokubeka usimende. Isetshenziswa njenge-coagulant ekwenzeni i-tofu, ukudla kwemvubelo, i-dough regulator, kanye ne-chelating agent. Kunezimayini zemvelo ze-gypsum, futhi imikhiqizo elandelanayo yemboni ye-phosphate iqukethe i-calcium sulfate. Isixazululo se-ammonium sulfate sisabela nesisombululo se-calcium chloride, futhi ukuhlunga, ukuwasha kanye nokukhipha imvula kungakhiqiza umkhiqizo omsulwa.

Isicelo

Ukucubungula ukudla:

I-calcium sulfate ingasetshenziswa njenge-ejenti yokwelapha ufulawa (njengesithako se-benzoyl peroxide), ngokusetshenziswa okuphezulu kwamagremu angu-1.5 ngekhilogramu; isetshenziswa njenge-coagulant ekucubungulweni kokudla. Isetshenziselwa ukwenza i-tofu, futhi cishe amagremu angu-14-20 ngelitha lama-soya ayengezwa kubisi lwe-soya (amanani amaningi azodala ukubaba). Yengezwa kufulawa kakolweni ku-0.15% futhi isetshenziswa njengomlawuli wokudla kwemvubelo kanye nenhlama. Yengezwa kutamatisi namazambane asemathinini njengesiqinisi sezicubu. Isetshenziswa njengesiqinisi samanzi kanye nesithuthukisi se-flavour yokwenza ubhiya. Ingasetshenziswa futhi njengesengezo sokudla.

Ukukhiqizwa kwezimboni:

1. Imboni yokwakha: I-calcium sulfate ingasetshenziswa embonini yokwakha ngezinto zokwakha, izinto zokuvikela ukushisa, izembozo, izinto zokuqinisa, njll. Amadevu e-calcium sulfate anokungqubuzana okuhle, ukulondolozwa kokushisa, ukuvikela ukushisa, ukuvimbela umlilo, ukuvikela ukuqhuma okungekhona okuqhuba ugesi kanye nezinye izakhiwo, futhi angathatha indawo ye-asbestos njengento yokungqubuzana, izinto zokuvikela ukushisa, kanye nezinto ezingashisi umlilo (ezivimbela umlilo). Isetshenziswa njenge-ejenti yamandla okuqala ezingxubeni zekhonkrithi, ngokuvamile enesilinganiso esingaba ngu-3%, ukulungisa isikhathi sokusetha nokuxuba nokugaya ku-simende. Lapho i-calcium sulfate ingezwa kukhonkrithi, inomphumela omkhulu wamandla okuqala.

2. Imboni yokwenza amaphepha: I-calcium sulfate isetshenziswa embonini yokwenza amaphepha ukuze ithathe indawo yengxenye noma ingxenye enkulu ye-pulp. I-calcium sulfate enesilinganiso esingaphansi noma esilingana no-50 ingasetshenziswa njengesigcwalisi sephepha esisezingeni eliphezulu, esingakhulisa kakhulu ukukhiqizwa kwephepha, sinciphise ukusetshenziswa kwezinkuni, futhi sisize ekuvikeleni imvelo futhi sinciphise ukungcoliswa kwamanzi angcolile.

3. Imboni yamakhemikhali: Embonini yamakhemikhali, ingasetshenziswa njengento yokuqinisa. Ama-whiskers e-calcium sulfate angenamanzi angasetshenziswa ekubunjweni kwepulasitiki ukuze kuthuthukiswe amandla ezinhlayiya zepulasitiki, ukumelana nokushisa okuphezulu, futhi kuncishiswe izindleko. Ekukhiqizweni kwamapulasitiki afana ne-polyvinyl chloride, i-polyethylene, i-propylene, ne-polystyrene, ingathuthukisa ukusebenza kwezici ezahlukahlukene zomkhiqizo, ithuthukise ubuncane, ukuzinza kobukhulu, ukuqeda ubuso, amandla okuthamba, amandla okugoba, i-modulus yokugoba kanye nokushisa kokuguquguquka kokushisa, futhi inciphise ukuguguleka kwemishini. Njenge-asphalt filler, ingakhulisa kakhulu iphuzu lokuthambisa le-asphalt.

Ezolimo:

I-calcium sulfate ingasetshenziswa njengomanyolo kwezolimo ukunciphisa i-alkalinity yenhlabathi nokuthuthukisa ukusebenza kahle kwenhlabathi.

Umuthi:

I-calcium sulfate inezinhlobo ezahlukene zezicelo embonini yezemithi. Ingasetshenziswa ukulungiselela imithi nokuhlinzeka ngezithako nezakhiwo ezidingekayo zemithi. Ngaphezu kwalokho, i-calcium sulfate isetshenziselwa nokwenza amaphilisi ukuqinisekisa ukuzinza nokusebenza kahle kwamaphilisi. Ngesikhathi esifanayo, ifakwa futhi ku-toothpaste ukuthuthukisa ukwakheka kanye nomsebenzi we-toothpaste. Lezi zicelo zibonisa ukubaluleka kwe-calcium sulfate embonini yezemithi, inikeza izithako ezibalulekile nezakhiwo zemikhiqizo yezemithi.
