Sodium metabisulfite wholesale, Ruihai chemicals (certified), Liupanshui metabisulfite

 Sulfur as raw material, the traditional process first sulfur wet pulverized into powder, compressed air feed eight burning furnace, and subjected to spontaneous combustion at 600 ~ 800 ℃, air is added in an amount of about 2 times the theoretical amount of gas SO2 concentration of 10 to 13 sodium metabisulfite synthesis, cooled and filtered to remove dust and sublimed sulfur and other impurities, and the gas temperature is reduced to about 0 ℃, passed through a series of reactors a third stage reactor and the mother liquor was slowly added with a soda aqueous solution secluded neutralization reactions. Its reaction is as follows: 2NaHSO4 + Na2CO3- 2 Na2SO4 + CO2 + H2O suspension of sodium sulfite are sequentially generated by the second stage, the first stage reactor, and the SO2 absorption reaction to produce crystalline sodium metabisulfite. Ideal food additives should be beneficial and harmless, but sodium metabisulfite manufacturers, absolute security is not realistic. China's health authorities for the use of food additives and use of the kind made strict rules, the use of food additives in the specified range generally harmless, but some companies or individuals driven by the interests of maximizing the use of additives or excessive use of industrial food additives in order to achieve improvement in the appearance and certain quality indicators to deceive consumers metabisulfite, consumer health damage. Widespread use of excessive use of food additives in food production and processing of food additive production process, beyond the scope of the use of food additives, the abuse of illegal additives and other issues. For example: sodium metabisulfite for lily superscalar processing, bleaching, corrosion, mildew; flour excessive use of benzoyl peroxide to make it look whiter; in some milk drinks, fruit drinks, preserves a large number of preservatives (benzoic acid), sweeteners (saccharin sodium, sodium cyclamate) and synthetic pigments to extend their shelf life and reduce costs. Excessive intake of food additives to harm human potential, in the short term is generally not a very obvious symptoms, long-term accumulation, the harm will appear. The main hazards health hazards: the goods on the skin and mucous membrane irritation obvious preservative sodium metabisulfite, can cause conjunctiva, bronchitis symptoms. People with allergies or asthma, are very sensitive. Direct skin contact can cause burns. Explosion hazard: This product is flammable, toxic, irritating.
