Frequently Asked Questions

As a leading Reagent Ammonium Bifluoride supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

What are the uses of reagent ammonium bifluoride?
It can be applied to the field of work, such as manufacturing, can make the lignin soluble, good and soft. In the field of work, it is used to clean fabrics, help them dye evenly, and color is bright. It is also very useful in the process of chemical synthesis. It is often used to control the acid and promote the reaction.
In addition, in the water treatment, the oxidation can reduce the pH value of the water, make it neutral or near neutral, remove harmful substances from the water, and retain water and clear. It is also useful in food production, for example, in cleaning food processing equipment to decontaminate and ensure the health of the equipment. It can also be used to improve the acidity of whole food, improve the taste of food, and increase its quality.
In addition, in the oil process of petroleum engineering, oxidation can reduce the amount of acidic substances in crude oil, remove oil, and extract oil. In metallurgical engineering, it can also help to lift gold, such as the lifting of oil, soluble soil, and the lifting of oil. In addition, oxidation plays an important role in many industries due to its specialization, and has many uses and is essential.
What are the storage conditions for the reagent ammonium bifluoride?
If you want to hide silver halide, you should be careful. Silver halide is sensitive to light, and it is easy to undergo chemical changes when exposed to light. Therefore, the most important thing to hide is to avoid light.
It should be stored in a dark vessel, such as a brown glass bottle. Its color is dark, which can block light and reduce the risk of it being changed by light. And the mouth of the bottle should be tightly stuffed to prevent air from entering. Cover the air or contain various things, which can be phased with silver halide and cause it to deteriorate.
And where it is hidden, it should choose a cool place to avoid heat and moisture. Heat can promote the speed of its chemical change, and moisture is easy to invade and damage its quality. If the place is fumigated by summer heat and wet, silver halide may not survive for a long time.
Furthermore, avoid co-location with sundries. The properties of silver halide may change with other things, so it is appropriate to store it in one place to prevent damage caused by confusion. And where it is stored, it is appropriate to check it regularly to see if it has any changes. If there are differences in color and shape, it will be known that it has changed and cannot be reused. In this way, by avoiding light, cooling, drying, storing alone, and observing from time to time, the medicament of silver halide can survive for a long time without losing its properties.
What safety precautions should be paid attention to when using the reagent ammonium bifluoride?
If you want to oxidize the stone, pay attention to the general safety matters. Those who oxidize the stone are corrosive, and the skin and mucous membranes of the stone are damaged. Therefore, when you use it, the first weight should be added to the body. It is necessary to wear corrosion-resistant clothing, such as rubber skirts and gloves, to prevent the liquid from reaching the body. And wear the eyes to ensure the safety of the eyes. If the liquid enters the eyes, it will be very harmful, and it will be stinging and bearable.
Furthermore, when mixing the solution, the operation should be careful. Oxidation will solidify the water, and it will not stop mixing, so you must not do the opposite. Because the oxidation will dissolve in water, and a large amount of water will be added. If the water is injected into the solid, it may cause the liquid to be damaged, and it will become difficult.
The method of storage should not be ignored. It should be placed in a dry and well-ventilated place, and it should be flammable and combustible. It is not safe to encounter other things or strong reactions. And keep it tightly to prevent it from absorbing and deliquescence, and to avoid the reaction of carbon dioxide in the air, which will cause it.
Use it to properly dispose of the liquid. Do not pour it out, so as not to pollute the environment. According to the phase, neutralize the treatment, so that the discharge can be used.
Use it to oxidize, be careful, and follow the procedures to ensure safety and make this stone suitable for use.
What are the physical and chemical properties of the reagent ammonium bifluoride?
The physicochemical properties of saltpeter can be studied. This is a chemical substance with similar characteristics.
One is solubility. In water, it is easily soluble and dispersed, and its molecules are all dissolved in water. If it enters the rivers and lakes, it will be integrated. When the water rises slightly, the more it dissolves, just like when it is warm in spring, it prompts flowers to flourish, and the solubility is also low.
Second, chemical activity. In case of acid, it will cause reaction, such as when it meets fire, it will melt new things, or it will grow and sink, or it will sink.
Third, its aqueous solution is very special. It is either acidic or acidic, and it is formed by it. This property is like a person's temperament, which is different, but it all affects the surrounding environment, in the middle of the reaction, and inhabits the place.
Fourth, when it is affected by the process, it also disintegrates. Or decomposes, or melts, molecules disintegrate and re-create, such as the dismantling of the plant, the construction of new plants, and the generation of new materials. Each has its own properties and its own capabilities.
The chemical substance of saltpeter, with its physical and chemical properties, is indispensable in the field of chemical processing, and has a wide range of uses. It is either a raw material for engineering or the assistance of scientific research, such as the stars in the night sky.
What is the production method of reagent ammonium bifluoride?
There is a way of boiling water in ancient times. In the past, the method of boiling the sea is the method that is often used. In the land of the sea, take seawater and fill it in a large kettle, and boil it with firewood. The seawater is heated, the water is steamed, and the amount of water is sold. When the water is lost, it is placed at the bottom of the kettle, take it and dry it, and you can get it.
There is also a method of well. In the land of Shu, there are many wells. Wells and springs, draw their water and go up. Also boiled in a large kettle, the method of cooking the sea is similar. However, the taste of well, or the method of sea.
And there is a method of pool. When there is a pool, as soon as the sky is full of flames, the water in the pool will be naturally steamed, and it will be washed at the bottom of the pool. But if people collect it and refine it, they can get white water. This is the method of water cultivation by the ancients.
When it is boiled in the sea, it is necessary to cook the sea, and the firewood is also sufficient. The well is not difficult, and it is difficult to study the well. The pool is taken from the pool, and it is difficult for the sky to obtain the benefits of the sky, so that the harvest can be obtained.
The method of water cultivation has its own suitability. According to local conditions and appropriate conditions, the ancients used their wisdom to create this method to meet the needs of people's livelihood, and the merit is great.
