Protection of hydrazine hydrate

Protection of hydrazine hydrate

Hydrazine hydrate is a very important chemical raw material in our daily life, in all fields has its shadow, in thermal power plant are anti-corrosion additives, also azo initiator, in agricultural chemical products and pharmaceutical products is also an important part. In industrial production is also have a lot of application.

In fact, in the pharmaceutical industry, hydrazine hydrate is a critical part of the production of various kinds of drugs, which is usually drug toxicity is we all said. Also often see in the consumer goods industry, it is also a kind of foaming agent. As well as our agrochemical industry. Urea is generated in the process of hydrazine hydrate. Hydrazine hydrate or rocket fuel and the formulation of the product. So hydrazine hydrate when can't get effective control is very damaging. If in the process of production have a large number of hydrazine hydrate leak what to do.

The first thing to do is to evacuate leakage pollution area personnel to safe areas, no irrelevant personnel enter the contaminated area, suggested that the emergency response personnel wear self-contained breathing apparatus, wear chemical protective clothing. Don't direct contact with the leakage, plugging in ensuring safety situation. Spray water, reduce evaporation. It incombustible adsorbent with sand or absorbed, and then collected to disposal of waste disposal places. You can also use a lot of water to rinse, diluting the wash water into wastewater system. Such as a large number of leakage, use of cofferdam asylum, and then collect, transfer, recycling and harmless treatment after the waste.

The harm of hydrazine hydrate is very big; if not timely processing waste pollution is extremely serious leakage. Waste liquid chlorine dioxide foam separation process and hydrazine hydrate by chlorine dioxide foam separation device, chlorine dioxide foam separation was studied in hydrazine hydrate class waste liquid treatment effect. Through the experiment focuses on the waste water pH, chlorine dioxide dosing quantity and reaction time on the influence of parameters on the effect of wastewater treatment. The optimum reaction conditions (i.e. pH value of 10, chlorine dioxide in waste water per liter dosing quantity is 5 mg / 1000 COD, the reaction time is 3 h) under the reaction, the original liquid waste (COD value of 30000-30000 mg/L, total ammonia nitrogen is 2500 ~ 2700 mg/L) after processing the COD removal rate reached 99%, ammonia nitrogen removal rate reached more than 96%.

If direct contact with hydrazine hydrate to clothing, immediately remove contaminated clothing and thoroughly rinse immediately with flowing water.

If contact with eyes, immediately filed a eyelid, with flowing water or saline flush at least 15 minutes. And then go to the hospital quickly.

If you accidentally splashed into his mouth, the most effective is to drink milk, or eat an egg, and then hurried to the hospital.

If accidentally breathe hydrazine hydrate please quickly from the scene to fresh air. Breathing difficulties to oxygen. Breathing stops, artificial respiration and then immediately go to hospital to check.

what is Nonionic surfactant？

Nonionic surfactant

Ions in aqueous solution does not produce a surface active agent. Nonionic surface active agent solubility in water is due to the molecule having a strongly hydrophilic functional group , non-ionic surfactants in the number of second anionic surfactant is a large class of important species used , as oil industrial development , raw material costs continue to decrease ethylene oxide , and its production will continue to increase .

Basic Application
Nonionic surface active agent in water is not ionized , is hydroxy (a OH) or an ether bond (R-O-R ') is a hydrophilic group amphiphilic molecular structure , a hydroxyl group and an ether bond as a hydrophilic weak Therefore, the molecule must contain a plurality of such groups - to demonstrate a certain degree of hydrophilicity, which is able to play only one hydrophilic group of anionic and cationic hydrophilic surfactants are very different. Because of non-ionic surfactant has not ionized in water, determined by the characteristics in some areas of its ionic surfactants representing superior, as in water and in organic solvents have good solubility , stable in solution high , less susceptible to strong electrolyte salts and acids, alkalis .

As it is with other types of surfactant compatibility, so often can be a good mix compound used . Non- ionic surfactants are excellent resistance to hard water , a low foaming characteristics, therefore suitable for special detergents. Because of its dispersion, emulsification , foam , wetting, solubilizing a range of performance , so in many important applications in both areas .
