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.

The application of silica gel desiccant in the electronics industry
Silica gel desiccant is very important in many industrial fields and general an operation. Dry material often due to the following one or more of the following reasons: to make good material flow, easy handling, storage, easy to save and reduce transportation cost, achieve desired product quality, etc. Need the variety of drying, they need the drying time of each different, each have different physical shape and quality requirements, improper drying can lead to poor product quality, product sale, cause irreparable damage.
In the electronic equipment has become so necessary in modern life, silica gel desiccant play to the role of the increasingly powerful, especially in small portable devices, such as pagers and mobile phones, once some of the most complex and most vulnerable to the environmental impact of any element equipment is affected, will not only bring pecuniary loss, may also affect the work and life. Compared with the replacement cost of these products, desiccant is a convenient and cheap alternative.
Under normal circumstances, there is an obvious example, such as camcorders, it can not run when there is no other explanation; desiccant may help you solve the problem, good as new!
Silica gel desiccant technology innovation refers to the at least one or more attributes can be instead of the original product, operation, or method: hadn't invented the manufacture, product or method; Have a higher productivity than the existing technology; More feasible quality or better quality control, the effect is better; Reduce equipment occupies the environment space; Operation more secure; More efficient; The total cost is reduced. New technology can be established a new type of products, such as: microwave drying, dielectric drying, etc. Can also be used to is a modest improvement on existing products, process, such as: jet impact dry, dry cyclone, etc.; and the major improvement of the existing technology, such as: organic superheated steam drying, desiccant, etc.
Silica gel desiccant the dry principle is based on the dry material and absorbs moisture of the solid in direct contact with the wet copy of transfer between the two. The dry form contains two kinds of drying technology. A is a typical dry contact: wet here of the evaporation only at the cost of solid surface heat transfer of heat. The second is the adsorption drying: wet here of the transmission is driven by a mass concentration gradient. Especially suitable for the needs of small, portable, or relative shortage of power users, is a kind of very promising drying technology, which can be widely used in chemical industry, food, medicine, and textile, biological and other industries.

Molecular sieve

Molecular sieve absorption capability is extremely strong, for purified gas, save should avoid direct exposure in the air. Longer storage time and moisture absorption of molecular sieve before use should be regenerated. Molecular sieve avoid oil and liquid water. Use should be avoided in contact with the oil and liquid water . Industrial gases in the drying process , air, hydrogen , oxygen , nitrogen , argon , etc. in parallel with two adsorptive dryer , a work, while the other can be regenerated . Alternating between work and regeneration, in order to ensure continuous operation of equipment . Work under the dryer at 8-12 , heated to 350 under the red gas regeneration. Different specifications slightly different molecular sieve regeneration temperature . Some organic molecular sieve has good catalytic gas phase reactions .
Also known as Molecular sieve is a crystalline aluminum silicate , its crystal structure has pores of regular and uniform pore size of the molecular size of the order of magnitude , than the pore diameter only allows small molecules to enter, so can molecules in the mixture to be screened according to size . So called molecular sieves.
As early as 200 years ago , B. Crone tter first named the aluminosilicate Molecular sieve , the chemical composition of the general formula wherein M and n is the valence of the metal ions and their ; x is silica molecules ; y is the number of molecules of water ; p is the number of atoms of aluminum ; q is the number of atoms of silicon . Molecular sieve in the chemical industry as a solid adsorbent, the adsorption material can be desorbed molecular sieve can be regenerated after use . Also for gas and liquid drying, purification , separation and recycling. 1960s began , in the oil refining industry as a cracking catalyst , and now has developed a variety of catalytic processes for different molecular sieve catalysts.
Performance
Powdered molecular sieve crystals with metallic luster , hardness of 3-5 , the relative density of 2 to 2.8 , a color of natural Molecular sieve , synthetic Molecular sieve is white , insoluble in water , thermal stability and acid resistance as the composition ratio of SiO2/Al2O3 increased with the increase . Molecular sieve has a large surface area , up to 300 ~ 1000m2 / g, the inner surface height crystal polarized efficient adsorbent as a class , also a kind of solid acid , the surface has a high acid strength and acid concentration , can cause carbenium ionic catalytic reaction .

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 .
