Painting knowledge- Hydrazine hydrate

    Hydrazine hydrate is also called diamide hydrate, which with strong basicity and hygroscopicity. The pure hydrazine hydrate is colorless transparent oily liquid with light ammonia smell. Hydrazine hydrate can smoke in wet air. In industry, the content of hydrazine hydrate solution is 40%-80%.
    Hydrazine hydrate is mainly used in producing the plastic, rubber foaming agent, drugs, pesticides and Organic synthesis high energy fuel. Among of them, the foaming agent use dominates 50%-60% of total amount. At present, the annual demand of Hydrazine hydrate is over 100,000 metric tons, and the Asian market has 35%. As far as China market concerned, the using amount in large thermal power station, Nuclear power plant construction, pesticide, medical plastic intermediates is increasing continually, and the market demand has developed quickly. Expected for a long time, the product will still maintain a higher profit margin, and it is a good product deserves producing for Chlor-alkali enterprises. 4 Production lines: Rasi method process (Already eliminated), Urea method, Bayer ketone method and Hydrogen peroxide method. Raw material consumption: 1t Hydrazine hydrate 40% will consume 2.6t Sodium hydroxide, 1 t Hydrazine hydrate 80% will consume 5.3t Sodium hydroxide. It is reasonable to equip the ADC foaming agent when build the Hydrazine hydrate equipments.
    Safety measures
    1. Health Effect
    Vapor Sucked, swallowed and absorbed through skin.
    2. Health hazardous
    Swallowing breathing of the vapor may harmful to nose andupper breathing tube of human being, resulting in sick feeling and nervous problems. Vapor may be severe eye irritation with swelling, burning, redness and discharge. It may cause permanent blindness for the worst condition. It may also cause allergic skin reaction, such as burning if contacting with skin. There exists risk of liver hazard if handling for long period with this product.
    3. First Aid Measures
    Skin contact: Remove polluted clothing and flush with large quantity of clean water for at least 15 minutes. Get medical attention immediately.
    Eye Contact: Lift eye lips and flush with large quantity of clean water or medical brine for at least 15 minutes. Get medical attention immediately.
    Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
    4. Explosion Features and Fire Fighting Measures
    Fire: Flammable when contact with fire flame. Top reductively. React severely with oxidates mercury oxide, metallic sodium etc, resulting in fire or explosion.
    Flash point: 72.8 ℃,
    Explosion low limit: 3.5%
    Explosion high limit: No records.
    Fire Fighting: Firemen must be covered with spraying water. Containers with H/H must be cooled with praying water. All over flowing must be diluted to safety content to avoid explosion and firing.
    Fire Distinguishing Media: Water spray, dry chemical, carbon dioxide, etc.
    5. Accidental Release Measures
    To withdraw all people in the area to safety places and restrict entrance. Isolate any possible fire sources. Handling people must wear self-contained breathing apparatus with full face pieces operated in the pressure demand. Leakage must be stopped as it can and to prevent it from entering ditches.
    Small Leakage: To cover the leaked H/H with sounds or other combustible materials or to flush with large quantity of water.
    Large Leakage: To transfer to effluent treading by tank truck or special collectors.
    6. Handling and Storage
    Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of heat or ignition. Protect against physical damage. Store separately from reactive or combustible material as well as oxide and acidic materials, and out of direct sunlight. It is suggested not to stop during transportation.
