The Methylene Chloride market has had a poor start to the year. Before the New Year's Day holiday, the maintenance equipment has been resumed, the overall market load has increased, the supply of resources is relatively comfortable, but the demand side performance continues to be weak, downstream
In the chemical industry, there are three common production methods of potassium hydroxide, i.e., diaphragm method, mercury electrolysis method and ion-exchange membrane electrolysis method. When we choose mercury electrolysis method for production, the risk is relatively high, because Mercury is a
Methylene chloride is predominantly used as a solvent. The acute effects of methylene chloride inhalation in humans consist mainly of nervous system effects including decreased visual, auditory, and motor functions, but these effects are reversible once exposure ceases.
When some areas enter the plum rain season, the air will become extremely humid, which will have a bad impact on food storage and people's normal life. In order to avoid the heavy losses caused by the weather in this period, many dehumidification products are widely used.
I. On potassium nitrate:1. Potassium nitrate is a compound fertilizer of nitrogen and potassium, of which nitrogen is 13.5 and potassium is 46. Potassium nitrate is easy to move in the soil and is suitable for Topdressing of crops, especially in the middle and late stages.
Whether the proportion of materials or the amount of water in evaporated water has a certain effect on the purity and yield of potassium nitrate. Then there is another kind of cooling crystallization temperature, which is called cooling crystallization temperature.
Product introduction and its useSodium metasilicate is listed as "China's priority development of fine chemicals" and "the future development of inorganic chemical products in China" one of the quality system in strict accordance with the national HG/T2568-94 standard implementation of production.
Sodium metasilicate pentahydrate, as often used in sodium metasilicate, a more typical variety, by virtue of soluble in water, insoluble in alcohol and acid, descaling, emulsification, and other effects are widely used in a variety of industries, especially in the washing industry,sodium metasilicate pentahydrate is a must for production.
