Ingabe i-anhydrous sodium sulphate iyafana ne-anhydrous sodium sulphite?
I-Sodium Sulphate Anhydrous, iyunifomu emhlophe ama-granules amahle noma impushana.
Ayinaphunga, inosawoti futhi iyababa.
Ubuningi 2.68g / cm. Iphuzu lokuncibilika 884 ℃.
Incibilika emanzini, ukuncibilika kukhuphuka ngokushesha ngokwanda kwezinga lokushisa phakathi kuka-0-30.4 ℃. Incibilika ku-glycerol, ayincibiliki ku-ethanol.
Isixazululo esinamanzi asithathi hlangothi. Uma isixazululo esinamanzi singaphansi kuka-32.38℃, sizokwenziwa ikristalu futhi sinethwe njenge-decahydrate.
Ngaphezu kuka-32.38 ℃, iqala ukucwebezela nge-anhydrous sodium sulphate.
Ikakhulukazi isetshenziswa njengokugcwalisa odayi nabasizi ukulungisa ukugxilwa kodayi nabasizi ukuze kufinyelelwe ukugxila okujwayelekile.
Ingasetshenziswa futhi njengodayi abaqondile, odayi be-sulphide, odayi abancishisiwe ekudayeni ukotini, odayi abaqondile be-asidi ekudayeni usilika wokudaya kanye ne-wool animal fibre retarder, ingasetshenziswa futhi njengokucwenga indwangu kasilika lapho i-ejenti yokuvikela umbala eyisisekelo.
Embonini yephepha, isetshenziswa njenge-ejenti yokupheka ekwenzeni i-sulphate pulp. Embonini yezemithi, isetshenziswa njengekhambi lobuthi be-barium usawoti.
Ngaphezu kwalokho, iyasetshenziswa nasezimbonini zezingilazi nezokwakha.
I-sodium sulfite anhydrous, i-crystal powder emhlophe, encibilika emanzini (ku-0 ℃, 12.54g/100ml amanzi; ku-80 ℃, 283g/100ml amanzi), ukuncibilika okuphezulu cishe ku-28% ku-33.4 ℃, isixazululo esinamanzi si-alkaline, i PH inani licishe libe ngu-9~9.5.
Incibilika kancane otshwaleni, ayincibiliki ku-liquid chlorine, ammonia. I-oxidized kalula ku-sodium sulphate emoyeni, futhi ibole ibe yi-sodium sulfide ekushiseni okuphezulu. Inombolo ye-CAS 7757-83-7.
Ukusetshenziswa kwamakhemikhali:
I-anhydrous sodium sulfite isetshenziselwa ukuthuthukiswa kwefilimu.
