Abstract
Provided are a rongalite solution stabilizing agent and application thereof in a liquid rongalite product. The stabilizing agent is composed of a buffer inhibitor, a chelating agent, a separating agent, a bactericide and an antioxidant. The buffer inhibitor, the chelating agent, the separating agent, the bactericide and the antioxidant can be independently applied or combed to be applied to rongalite solution made of a solid rongalite product or rongalite liquid (sodium formaldehyde sulfoxylate solution) in the rongalite product production process according to the requirements of different stabilizing time, so that the liquid rongalite product is directly prepared. The rongalite solution stabilizing agent can meet the performance requirements of rongalite products for industries such as synthetic rubber and dyeing and finishing, is convenient to use, and can maintain enough stability in the using process.
Description
Technical field
The present invention relates to stablizer and the application in liquid rongalite products production thereof of rongalite solution, belong to the chemical industry technical field.
Background technology
Rongalite, chemical name is sodium bisulphite formaldehyde, is mainly used in making discharging agent on the printing and dyeing industry, and the activator in the styrene-butadiene rubber(SBR) polymerization.
The heat release of rongalite moisture-sensitive; Should be in (pH＞8) in the weak alkaline medium, meet acid and namely decompose; Have strong reductibility, meet oxygenant, such as I
2Also can decompose; 120 ℃ of lower toxic gases such as producing formaldehyde, sulfurous gas and hydrogen sulfide that decompose.The rongalite aqueous solution is just beginning to decomposite objectionable impurities more than 80 ℃:
6NaHSO
2·CH
2O+3H
2O＝4NaHSO
3+2HCOONa+2H
2S+HCOOH+3CH
3OH
Common rongalite solution begins slow decomposition after 2～3 days, accelerate decomposition after the week, and usually in initial ten days, decompose very fast: bacterium and microbes accelerate its decomposition; Divide the acid that parses also can promote to decompose; Dissolved oxygen in the existence of illumination and heavy metal ion, airborne oxygen and the water can make its oxygenolysis.Therefore, rongalite solution has stronger unstable, has affected storage and the use of rongalite solution or liquid rongalite product.In addition, the solid rongalite needs dissolution filter in use, and because the turbid solution filtering that forms of when dissolving bothers relatively, need to measure many-sides such as solid, component and liquid, and is comparatively loaded down with trivial details and time-consuming bothersome.
Summary of the invention
The object of the present invention is to provide a kind of rongalite solution to be had better stabilising effect, itself is nontoxic, and physico-chemical property is stable, does not affect the stability of involved thing, reductibility, the water-soluble and stablizer that uses.
The object of the present invention is achieved like this, stablizer is comprised of buffering and inhibitor, sequestrant, barrier agent, sterilant and antioxidant, these components can be according to the needs of different steady times alone or in combination, in the rongalite solution or the white liquid of the carving in the rongalite process of producing product (sodium bisulphite formaldehyde solution) that is applied to be become by solid rongalite product configuration, directly be mixed with liquid rongalite product.
Buffering in the stablizer and inhibitor are sodium hydroxide-yellow soda ash combination, potassium hydroxide-yellow soda ash combination, yellow soda ash-sodium bicarbonate combination or yellow soda ash, and rongalite solution is 1: 0.060～0.083 with the ratio of the mass concentration of buffering and inhibitor; For A, the combination of B two-pack, A is 1: 0.30～0.60 with the ratio of the mass concentration of B; Sequestrant is disodium ethylene diamine tetraacetate, Trisodium Citrate or Seignette salt etc. have good sequestering power with heavy metal ion under weak basic condition sequestrant, and rongalite solution is 1: 0.005～0.020 with the ratio of the mass concentration of sequestrant; Barrier agent is tensio-active agent or grease chemical article (carbon number is at the lipid acid more than 8 and 8 and salt thereof), and rongalite solution is 1: 0.005～0.020 with the ratio of the mass concentration of barrier agent; Sterilant and antioxidant are take organic sterilant or antioxidant as main (comprising phenols, epoxies, amine and inorganic salt, such as ammonium salt, magnesium salts), and the volume of this component is 0.1～5.0 kilogram of every cube of solution.
When using solid rongalite product configuration rongalite solution, mass concentration according to liquid rongalite product, first with the solid rongalite product of certain mass and buffering and the inhibitor of corresponding addition, boil the pure water dissolving of cooling with certain volume, again as required, add respectively a certain amount of sequestrant or barrier agent or sterilant and antioxidant after the filtering; Or with the disposable adding of stablizer all components, the dissolving filtering with the packing of weighing of clean dry plastic barrel, covers tightly inside and outside bung again.
When in the production process of conventional rongalite product, directly using stablizer of the present invention, in the white liquid of carving in the rongalite process of producing product (sodium bisulphite formaldehyde solution), mass concentration and volume according to the white liquid of carving, add a certain amount of buffering and inhibitor, filtering after the stirring and dissolving adds respectively a certain amount of sequestrant or barrier agent or sterilant and antioxidant, the stirring and dissolving filtering again, with the packing of weighing of the plastic barrel of clean drying, cover tightly inside and outside bung.
Compared with prior art, the present invention's uniqueness of filling a prescription is prepared easyly, and raw material is easy to get, and uses safety, and rongalite solution is had the satisfactory stability effect.
