Rongalite lump,Rongalite powder, Rongalite granules are of a sort but in various forms,their chemical composition is all the same. Three types of Rongalite product are supplied to meet customer’s calls for in software.
Chemical Title : EPT Formaldehyde Sulfoxylate
Professional Title : RongaEPT C
Molecular Formula : NaHSO2 middotCHtwoO middot2HtwoO
Molecular WeigEPT : 154.twelve
Distinct Gravity :1.8
Melting Point : sixty four ordmC
Warmth of Fusion :fifty four.84 KJ/mol( 13.2Kcal/mol)
Hygroscopic Position : Relative Humidity 60%
Stable Pour-Stage :50 ordmC max
45%(twenty ordmC):one.two dose of water is required for dissolving away one dose of Rongalite at 20 ordmC. fifty%(70 ordmC):one dose of water is required for dissolving avay one dose of Rongalite at 70 ordmC.
To be nominated for Rongalite is for the cause that it serves the coloration-discharging functionto fabrics as effectively as its physical appearance. UnEPTdifferent cooling problems, it solidfies out into white lumps, powder, or granules.
Presenting a EPTful reduction conduct, it functions as a salt of alkaline defense.
a. Simple to deliquescent, emit warmth, get started to decompose at eighty ordmC, and sulfurated hydrogen HtwoS being launch:
6NaHSO2 middotCHtwoO+3H2O – #85944NaHSOthree+2HCOONa+2HtwoS+HCOOH+3CHthreeOH
b.Decompose fully when the temperature rises to one hundred ten ordmC, the intramolecular formaldehyde are splitted out, and then nascent hydrogen which is possessed of the strongest minimizing EPT are made :
NaHSO2 middotCHtwoO – #8594 NaHSOtwo+ CHtwoO
NaHSO2 + HtwoO – #8594 NaHSO2+ 2[H]
c.UnEPTthe impact of acidity, decompose at PH gt3, emit H2S, so that it sould be existing in alkline medium PH gt8.
d.Decompose on making contact with oXiHu (West Lake) Dis.dant, just take Itwo for case in point:
NaHSO2 middotCH2O+2H2O+2I2 – #8594 NaHSO4+4HI+CH2O
2. StXiHu (West Lake) Dis.Hu (West Lake) Dis.rd: up to the StXiHu (West Lake) Dis.Hu (West Lake) Dis.rd HG 228I-1992
|Articles of NaHSO2 middotCH2O % ge||98.|
|State of solubleness||Drinking water remedy distinct or microturbid|
|Sulphide||No existence of black coloration is allowed|
|Smell||No odor or a minor scent of leek|
In plastic bag Net bodyweight: 25kgs each.
It is largely used as a discharging agent, colour-discharging agent, reductant in printing and dyeing industry, as an activating agent for generation styrene-butadise rubber and artificial resin, also be utilized to decolourize and bleach some natural and organic matters, for case in point: as a bleaching agent in artificial rubber, suXiHu (West Lake) Dis.Hu (West Lake) Dis.-producing, and food EPT. It could be substituted for the sodium hydrosulfite in some EPT situations.
Ought to be saved in a dry, great and dim area, secured, from humidity, averted exposure to immediate sunshine, do not to allow it be rained on. Be certain not to keep it jointly with oXiHu (West Lake) Dis.dant and acid, no existence of acidic vapour in storeroom is authorized. Storage lifestyle is a single year.
