The warehouse temperature should be controlled below 30 ° C, and the humidity should be below 80%.
Second and container material. Corrosion-resistant materials should be selected, such as glass, ceramics or containers made of specific plastics. Metal containers are easily corroded by ammonia, causing the risk of leakage. And the container must be well sealed to prevent ammonia from escaping, polluting the environment and harming the human body.
Furthermore, avoid mixed storage. Do not store with acids, metal powders, halogens and other substances. Ammonia water meets acids and will react violently; contact with metal powders or cause chemical reactions; mixing with halogens may also cause dangerous reactions.
Fourth, the storage place should be equipped with obvious warning signs to remind personnel that this is a dangerous chemical. And it should be equipped with corresponding emergency treatment equipment and protective equipment, such as eye washers, gas masks, etc.
Finally, check regularly. Check whether the container is damaged or leaked, and monitor the temperature and humidity of the storage environment to ensure storage safety. Once any abnormalities are detected, measures must be taken to dispose of them in time to ensure the safety of personnel and the environment.
What are the transportation requirements for 20% Ammonia Water?
20% ammonia water (20% Ammonia Water) is a commonly used chemical material, and its transportation and transportation must strictly abide by the specifications to ensure safety and prevent leakage.
When transporting, the vehicle must have the qualification for transporting hazardous chemicals, and the driver and escort personnel must undergo professional training, familiar with the characteristics of ammonia water and emergency treatment methods. Vehicles should be equipped with corresponding safety equipment, such as fire extinguishers, leakage emergency treatment tools, etc., and regular security inspections to ensure good operation. During transportation, it is necessary to prevent bumps and collisions from causing damage to the container.
In terms of transportation, the pipeline material must be resistant to ammonia corrosion, firmly installed and well sealed to prevent leakage. Before transportation, the pipeline system should be fully inspected to ensure that there is no blockage or damage. During the conveying process, it is necessary to closely monitor the pressure, flow and other parameters, set a reasonable alarm value, and dispose of it in time when it exceeds the limit. If a pump is used for conveying, the selection of the pump should be adapted to ensure stable and reliable operation, regular maintenance, check the sealing performance, and prevent leakage.
The container for storing ammonia should be placed in a cool and ventilated place, away from fire and heat sources, and stored separately from acids and metal powders. Do not mix storage. The storage container should be checked regularly to see if there are any signs of corrosion or leakage.
When loading and unloading, the operation should be light and light to prevent damage to the container. Operators must wear appropriate protective equipment, such as gas masks, rubber gloves, protective clothing, etc., to avoid physical injury caused by contact with ammonia. Flushing equipment and emergency rescue drugs should be prepared on site to respond to accidents in a timely manner.
In short, the transportation and transportation of 20% ammonia, from personnel qualifications to equipment maintenance, from storage conditions to loading and unloading operations, every step is related to safety. It must not be taken lightly. It must be strictly implemented in accordance with regulations to ensure safety.
What are the dangers of 20% Ammonia Water to the human body?
20% - 25% ammonia water does have many hazards to the human body. This is due to the ammonia in ammonia water, which is highly irritating and corrosive.
If it comes into contact with the skin carelessly, it can cause skin burns. At first, the skin feels tingling, followed by redness and swelling. If the contact is long and the concentration is high, it may cause blisters, ulcers, and the wound heals slowly, or leaves scars, affecting the appearance and function of the skin.
If it comes into contact with the eyes, it is particularly harmful. Irritation of ammonia can cause severe eye pain, tears, redness and swelling. In severe cases, it can damage the cornea and conjunctiva, and even lead to vision loss. If the treatment is not timely, it may cause blindness.
If inhaled ammonia-containing volatile ammonia air, it will irritate the respiratory tract. Light cases can cause cough, asthma, chest tightness, and severe cases can cause laryngeal edema and pulmonary edema, which affect gas exchange and endanger life. Long-term low-concentration exposure may cause chronic respiratory diseases, such as chronic bronchitis, emphysema, etc., and reduce respiratory system function.
If ingested ammonia by mistake, it will burn the oral cavity, esophagus, and gastric mucosa. Cause severe pain in the oral cavity and throat, burning sensation, and nausea, vomiting, vomiting, or bloody liquids. Damage to the esophagus and gastric mucosa may cause serious complications such as perforation and bleeding, causing great damage to the digestive system and threatening life and health. Therefore, when exposed to 20% to 25% ammonia, it is necessary to take protective measures and exercise caution to avoid damage to the human body.
How is 20% Ammonia Water produced?
The method of preparing ammonia water from 20% to 25% is very elegant. Most of the ammonia gas is taken first and passed into the water to form this liquid.
To make ammonia water, the first thing to do is to obtain ammonia gas. The preparation of ammonia gas is often by the method of co-heating ammonium salts and alkalis. If ammonium chloride and calcium hydroxide are taken, the two are placed in a closed container in an appropriate proportion to heat together. Ammonium chloride and calcium hydroxide combine to produce ammonia gas, calcium chloride and water. The chemical formula is: 2NH Cl + Ca (OH) ² = CaCl (OH) ³ + 2NH 🥰 + 2H ² O. The generated ammonia gas is passed into the water through a tube that conducts gas.
Ammonia gas has a considerable solubility in water. When it enters water, ammonia molecules interact with water molecules, and some ammonia gas combines with water to produce ammonia monohydrate (NH 🥰 · H2O O). This process of synthesis is reversible. However, when preparing ammonia water, the ammonia gas is used to move the reaction in the direction of generating ammonia monohydrate.
When preparing 20% - 25% ammonia water, the amount of ammonia gas and the amount of water need to be precisely controlled. If there is too much ammonia gas, the concentration of ammonia water is too high; if there is too little, the concentration is not enough. When preparing, it is also necessary to pay attention to the temperature of the reaction. If the temperature is too high, the solubility of ammonia in water will decrease, which is not conducive to the formation of ammonia water; if the temperature is too low, the reaction rate will be slow.
The prepared ammonia water is alkaline because one of the ammonia hydrates can be partially ionized, and the raw ammonium ion (NH) and hydroxide ion (OH). Ammonia water is volatile. When storing, it needs to be sealed in a cool place to prevent ammonia from escaping and reducing the concentration.
