How can we contact sodium sulfide flakes producers?
News Group: News Group 2 [ 11 February 2022 ]

Sodium sulfide is a raw material that is used in many fields. This substance is usually available in solid form and has a pale yellow color. This combination can be used in various industries to facilitate the production process of products. Sodium sulfide is generally produced by manufacturers to be used in the textile, chemical, and dye industries, the paper industry, the detergent industry, and more. Sodium sulfide flakes producers generally use a variety of methods to get the product you need. If you want to know more about the production methods of this material, join us.

How can we contact the sodium sulfide flakes producers?

If you are looking for reputable sellers or you want to reduce your costs, you can contact the sodium sulfide flakes producers. Due to the high volume of sodium sulfide used in various industries, many manufacturers around the world produce it. This makes it easier for you to contact the sodium sulfide flakes producers if you need to buy the product you need. The only thing you need to do is a little query or internet search. Note that you can buy the product you need at relatively lower prices by contacting sodium sulfide flakes producers and saving as much money as you can. Buying from a manufacturer will usually help you pay a lower price for your product.

Investigate the methods used to produce sodium sulfide

In general, there are three methods for sodium sulfide flakes producers to produce sodium sulfide that we want to name for you.

Production of sodium sulfide by reduction of sodium sulfate with coal

In this method, sodium sulfide producers use sodium sulfate and coal as raw materials. First, sodium sulfate and coal are mixed in a ratio of 2 to 1, then about 5% sodium carbonate is added to it, which on the one hand accelerates the reaction flow and on the other hand a factor to neutralize any It acts on free acid. The mixture is placed in a reflection furnace at a temperature of 1000 ° C so that it takes about 2 to 2.5 hours to complete the reduction process. Different types of sodium sulfide with light brownish yellow colors are obtained by this method. But if we want to produce white sodium sulfide crystals, it will be possible by adding about 0.5% sodium cyanide (sodium cyanide) to the liquid before crystallization.

Production of sodium sulfide by the reaction of hydrogen sulfide and sodium hydroxide

In this method, sodium hydroxide with a concentration of about 38% is injected into the tower to react with hydrogen sulfide gas. As a result of this reaction, the intermediate product of sodium hydrosulfide is produced.

Electrolysis of sodium chloride and hydrogen sulfide salts

This reaction takes place at a temperature of 50 ° C and a pressure of 3 atmospheres. In this way, the obtained sodium hydrosulfide enters the next stage of the process after completing the adsorption operation by the pump. It should be noted that if needed, sodium sulfide flakes producers can remove the intermediate product of sodium hydrosulfide from the production cycle at this stage and after concentrating and filling the market as a product.

The production process of sodium sulfide flakes

In the final stage, after sodium sulfide is produced through these three methods, the resulting sodium sulfide enters the evaporation stage and its vapors are completely separated by separators. Finally, the material obtained in this step is placed in cold water after entering the submersible pump. A layer of sodium sulfide liquid inside the floating bed adheres to the cylinder and is eventually crystallized from the cylinder by spatulas. Eventually, this substance enters the flaking machine and is known as sodium sulfite flakes. This material enters the packaging sector and finally enters the market in different packages.
