Sodium Sulphide Flakes CAS No.1313-82-2

Lus piav qhia luv luv:

Sodium sulphide yog daj lossis liab flakes, muaj zog noo noo nqus, soluble hauv dej, thiab cov dej daws yog cov tshuaj tiv thaiv alkaline.Txoj kev daws teeb meem hauv huab cua yuav maj mam oxygen mus rau sodium thiosulfate, sodium sulfite, sodium sulphide thiab sodium polysulfide, vim tias sodium thiosulfate qhov kev tsim tawm sai dua, nws cov khoom loj yog sodium thiosulfate.Sodium sulphide yog deliquesced nyob rau hauv cov huab cua thiab carbonated thiaj li hais tias nws yog metamorphic, thiab tas li tso hydrogen sulfide gas.Kev lag luam sodium sulfide suav nrog impurities, yog li nws cov xim yog xim liab thiab daj.Tshwj xeeb lub ntiajteb txawj nqus thiab boiling point yog cuam tshuam los ntawm impurities.

Khoom:

Daj los yog liab flakes, muaj zog noo noo nqus, soluble nyob rau hauv dej, thiab dej tov yog muaj zog alkaline cov tshuaj tiv thaiv.Sodium sulfide yuav ua rau kub hnyiab thaum kov ntawm daim tawv nqaij thiab plaub hau.

Sodium thiosulfate, sodium sulfite, sodium sulphide thiab sodium polysulfide, vim hais tias sodium thiosulfate generating ceev ceev, nws cov khoom loj yog sodium thiosulfate.Sodium sulphide yog deliquesced nyob rau hauv cov huab cua thiab carbonated thiaj li hais tias nws yog metamorphic, thiab tas li tso hydrogen sulfide gas.Kev lag luam sodium sulfide suav nrog impurities, yog li nws cov xim yog xim liab.
