Ammonium bifluoride, Solid is mainly used for what?
Ammonium hydrogen fluoride, solid, has a wide range of uses. In the art of etching, it is often used to etch glass, silicon wafers, etc. On glass, if you want to form delicate patterns or specific shapes, ammonium hydrogen fluoride can exert its work. The processing of silicon wafers also relies on its force to precisely etch, so that the silicon wafer is bonded to the needs of electronic devices.
is also used in the field of metal surface treatment. Before the metal is to be plated or coated, ammonium hydrogen fluoride can remove surface oxides and impurities, making the metal surface clean and active, and making the subsequent plating and coating more solid.
In chemical analysis, it is also useful. It can be used as a reagent to assist in the determination of certain elements. It can complex with specific metal ions or participate in chemical reactions to assist in the composition and content of analytical substances.
For wood preservative, ammonium hydrogen fluoride can also be used. Can penetrate wood fibers, prevent bacteria, insect moths, and extend the service life of wood.
And in ceramic production, it can also be seen. It can improve the performance of ceramic bodies, help the fusion and adhesion of glazes, and make ceramic products more perfect, with better texture and appearance.
Ammonium bifluoride, Solid in storage need to pay attention to what?
Ammonium hydrogen fluoride, solid, should be careful when hiding. First, this is a corrosive material, strong in nature, soluble in water, and when dissolved or heat, so it must be stored in a dry place, protected from water and moisture. The warehouse must be high and open, no risk of rainwater leakage, and no underground moisture return.
Second, ammonium hydrogen fluoride has the ability to corrode metals, and the reservoir should not be made of metal materials. Plastic, ceramic and other corrosion-resistant devices should be selected. And the container must be tightly closed to prevent it from contacting with outside air and water vapor, causing qualitative change or escaping harmful gases.
Third, this agent has a certain toxicity, and the place where it is stored should be well ventilated to prevent gas accumulation and damage to humans and animals. And it should not be stored in the same place as food and beverages to avoid its pollution and cause people to eat it by mistake.
Fourth, the storage place should be kept away from fire and heat sources, because it is heated or decomposed to release toxic gases. Do not put flammable or explosive objects around to prevent accidental changes.
In addition, the person in charge of the treasure should have professional knowledge, understand its nature and know its risks. When entering and leaving the warehouse, you must follow regulations and wear protective equipment, such as gloves and masks, to protect yourself. And always check its storage condition, if the container is damaged or deteriorated, dispose of it immediately to avoid disaster.
Ammonium bifluoride, Solid transport requirements?
Ammonium hydrogen fluoride, solid, that is, ammonium hydrogen fluoride solid, its transportation requirements are quite critical. This material is corrosive and toxic, and transportation must follow strict regulations.
First, the packaging must be solid and sealed. Commonly used packaging forms such as plastic drums and iron drums lined with plastics to prevent leakage. For example, iron drums need to ensure that the inner wall is smooth, no sharp edges cause package damage, and the lid is tightly sealed and can withstand a certain pressure.
Second, the transportation vehicle should be selected to be suitable. Anti-corrosion and anti-leakage facilities should be provided. For example, the car body needs to be treated with anti-corrosion treatment and anti-drip and leakage devices. If transported by tank truck, the tank material should be resistant to ammonium hydrogen fluoride corrosion and have reliable safety accessories.
Third, transportation personnel must undergo professional training. Familiar with the characteristics, hazards and emergency treatment measures of ammonium hydrogen fluoride. For example, know how to use suitable materials to adsorb, neutralize, and use their own protective equipment correctly after leakage.
Fourth, protect against sun exposure, rain and high temperature during transportation. Because high temperature may decompose ammonium hydrogen fluoride or increase its corrosiveness, shading and cooling measures are required for summer transportation.
Fifth, strictly follow the specified route. Avoid sensitive areas such as densely populated areas and water sources to reduce the risk of accidents.
In short, ammonium hydrogen fluoride solid transportation, packaging, vehicles, personnel, environment and routes all need to be treated with caution to ensure transportation safety.
Ammonium bifluoride, Solid what harm to the human body?
Ammonium hydrogen fluoride, solid, is extremely harmful to the human body. This substance is highly corrosive, and when it touches the skin, it can cause severe pain and burn marks. If it enters the eyes, it will be damaged, and even the risk of blindness. Inhaling its qi is also dangerous, irritating the airway, causing coughing, shortness of breath, long-term inhalation or damage to the lungs, and the disease is difficult to cure. If eaten carelessly, the stomach and intestines will suffer from its harm, severe pain, ulcers, and even perforation, endangering life.
Its poison is not only present in the immediate injury, or the long-term disease. Long-term exposure can damage bones and nerves, make limbs weak, numb, and the mind may be disturbed. Or cause blood lesions, loss of qi and blood, and various diseases.
Therefore, in ammonium hydrogen fluoride solids, people should stay away. When handling, the protection must be comprehensive. If there is any carelessness, seek medical treatment quickly and do not neglect it.
Ammonium bifluoride, Solid first aid measures?
In case of emergency spreading of ammonium hydrogen fluoride solid, the following methods should be used to dispose of it.
This ammonium hydrogen fluoride solid is corrosive and can hurt the skin and eyes when touched. If inhaled or ingested, it is also harmful to health. Therefore, once spreading, the first protection. The rescuer must wear protective clothing, goggles and protective gloves to prevent themselves from being harmed.
Then, quickly tell unrelated people to stay away from the spreading place and set up warning signs to prevent others from accidentally involving the dangerous place.
If the amount of spreading is small, you can use a clean shovel to gently collect it in a suitable container. After collecting, rinse the spreading place with a lot of water to remove the residue.
If the amount of spreading is large, do not dispose of it rashly. Try to cover it with inert materials such as sand and vermiculite to prevent it from spreading. Then, call a professional hazardous chemical treatment team. They have professional equipment and knowledge to deal with this situation properly.
During the treatment process, do not directly touch the spreading material with your hands, and do not let the cleaning water flow into the sewer, etc., so as not to pollute the environment. And the collected spreading material should be properly disposed of in accordance with the regulations of hazardous waste, and must not be discarded at will. In this way, the safety of personnel can be guaranteed and the environment is protected from harm.
