Said ammonia, the first reaction is very smelly, the bathroom is the highest place in the ammonia concentration in our family, actually ammonia source of the family is not so simple, just the bathroom first, let's learn about the nature of the ammonia, ammonia is a colorless and a strong irritating smell gas, ammonia solubility is extremely high, so often by adsorption on the skin mucous membrane and eye mucous, causing irritation and inflammation. It has a corrosive and irritating effect on all tissues in contact. It can absorb the water in the tissue, denaturate the tissue protein, saponify the tissue fat, and destroy the cell membrane structure.

In fact, the ammonia gas in the family mainly comes from the concrete admixture used in the construction, but also from interior decoration materials, such as the additives used in furniture finishing and whitening agent are mostly containing ammonia water. Especially in the construction process of winter, the concrete antifreeze agent with urea and ammonia water added in the concrete wall as the main raw materials, these contain a large number of additives in the wall with the change of temperature and humidity and other environmental factors and reduce to ammonia gas slowly released from the wall, resulting in a large increase in the content of ammonia in indoor air. Although this kind of pollution release period is relatively short, will not accumulate in the air in large quantities, but the harm to the human body is relatively small, but should also cause attention.

Ammonia plant

Ammonia gas has certain harm to human body, but we can not ignore the role of the big. First of all, we have a detailed understanding of the properties of ammonia gas, high purity ammonia gas

High purity ammonia is a colorless, toxic, alkaline, highly corrosive, flammable gas with an irritating odor. In high concentrations, it can irritate the eyes, skin, and mucous membranes. Ammonia is less dense than air, with a density of 0.7081g/L under standard conditions. Ammonia gas is highly soluble in water and can dissolve 700 volumes of ammonia in one volume of water at room temperature and pressure. The saturated vapor pressure of liquid ammonia at 21.1°C was 7.78 KGF /cm2. Fill with 40L cylinder, 43LDOT cylinder Y can or tank truck.

High purity ammonia is mainly used in the field of new optoelectronic materials. It is an important basic material for preparing GAN by MOCVD technology. GAN produces high sensitivity blue light emitting diode and blue light laser, as well as other related electronic devices, which is an industry that is in the market both at home and abroad. High purity ammonia or preparation of nitrogen trifluoride, silicon nitride, the basic material, is the production of super high nitrogen raw gas. In addition, liquid ammonia is widely used in the semiconductor industry, the metallurgical industry, and other industrial and scientific research in need of atmosphere protection.
