Zvemuviri uye zvemakemikari zvivakwa zve sodium hydrosulphhide (nahs)
1. Zvivakwa zvemuviri
Chitarisiko: Sodium hydrosulfide inowanzove chena kana kuti yakajeka yero crystalline poda. Inogona zvakare kuve isina ruvara kune yero, yemaune crystal ine hydrogen sulfide kunhuhwirira kunhuhwirira.
Inline polting point: Iyo yekunyungudutsa nzvimbo yeiyo ashydrous sodium hydrosulfide ndeye 350 ° c; Iyo yekunyungudika yendepe yeiyo hydrate yakaderera, pana 52-54 ° C. Nekudaro, imwe data inoratidza kuti inonyungudika nzvimbo yeSodium hydrosulfide ndeye 55 ° C.
Density: Iyo density ye sodium hydrosulfide ndeye 1.79 g / cm³, cm³, kana 1790 kg / m³.
Solubility: Sodium hydrosulmide inokanganisa mumvura uye nedoro, uye mhinduro kwayo kwemvura ndeye alkaline. Sekureva kweimwe data, iyo solubility ye sodium hydrosulfide mumvura ndeye 620g / l pa 20 ° C.
2. Makemikari zvivakwa
Acidity uye alkalinity: mhinduro yemukati yeSodium hydrosulfide is alkaline.
Reaction neAcid: Sodium hydrosulfide inoburitsa hydrogen sulfide gasi kana ichisangana acid. Iyo yekuita equation ndeye: Nah + H + → H2s ↑ + na.
Kuita neSulfa: Sodium Hydrosulfide inogona kuita nesarufa kuti aumbe polysulfides, iyo equation equation ndeye: 2nahs + 4s → Na2ss4 + h2s.
Kuderedza: Sodium Hydrosulfide iri inowanzo shandiswa kuderedza mumiririri anogona kuitwa neye redox maitiro ane mazhinji oxidants.
3. Zvimwe zvivakwa
Kugadzikana: Sodium hydrosulfide inzvimbo yakagadzikana, asi iri hygrapic. Panguva imwecheteyo, iriwo yakasimba inopisa uye inogona kukanganisa mumhepo.
Utongedzeka: Sodium hydrosulfide ine chepfu kune imwe nhanho uye inokuvadza kumuviri wemunhu uye zvakatipoteredza. Naizvozvo, kutarisisa kwakakosha kunofanirwa kubhadharwa kuchengetedzwa kwekuchengetedza panguva yekushandisa nekuchengetedza.
Parizvino, kambani iri kuwedzera nesimba misika yemakungwa uye nyika yepasirese.
Mumakore matatu akatevera, takazvipira kuve mumwe wevatakuri vegumi vekunze muChina
Kurongedza
Nyora imwe: 25 KG PP mabhegi (dzivirira kunaya, kudzvinyirira uye kufumurwa kwezuva panguva yekufambisa.)
