Potassium hydroxide is a kind of chemical reagent which is commonly used in our industry. In the process of using it, we find that it has the function of bleaching and disinfection. In the process of production, the sewage discharge equipment of enterprises can also be upgraded and purified. In our life, there are many bleaching applications for hydrogen peroxide. It is a kind of reagent which is cheaper. Then, what kind of substance has been compared between the two reagents? What about better performance?
The application of hydrogen peroxide is relatively extensive. In our life, we can use hydrogen peroxide in bleaching treatment. We can bleach cotton fabric in textile industry, and color the dyed clothes. These are technical improvements.
However, industrial potassium hydroxide, which is irreplaceable in industrial production, is also widely used in many fields such as medicine, chemical industry, military and so on. It can also be used as a bleaching disinfectant. Industrial potassium hydroxide has already formed a cohesive force in the market, and it always maintains its advantages in the competition with similar products.
In the era of economic development and technological innovation, the use of potassium hydroxide is obviously higher than that of hydrogen peroxide, its application scope is obviously more than that of hydrogen peroxide, and its performance is more advantageous than that of hydrogen peroxide. In the modern era of continuous development and reform of economic and industrial technology, potassium hydroxide has more value and development advantages.
When it comes to liquid potassium hydroxide, the first thing the editor thinks about is the contact in chemistry class. It is corrosive. Therefore, we should pay attention to the safety precautions when using and storing. The precautions for using liquid potassium hydroxide have been told to you before. Here we summarize the storage of solution:
一：首先少量的此溶液可以存放在玻璃瓶，但是不能用玻璃塞（一般是用木塞，胶塞），因为普通玻璃的组成中含有较多的二氧化硅，它们会发生反应：2NaOH + SiO2=Na2SiO3 + H2O，其中反应物硅酸钠具有粘稠性，会使塞子黏住导致开不了。
First, a small amount of this solution can be stored in glass bottles, but not glass stoppers (usually wooden stoppers, rubber stoppers), because the composition of ordinary glass contains more silicon dioxide, they will react: 2NaOH + SiO 2 = Na2SiO 3 + H 2, in which the reactant sodium silicate is viscous, will cause the stopper to stick and not open.
2. Store large quantities of solution in a ventilated and dry warehouse or shed.
1. Packaging containers should be complete and sealed.
2. It is not allowed to be stored and mixed with flammable substances and acids.
3. Attention should be paid to moistureproof and rainproof.
4. Water, sand and various fire extinguishers can be used to extinguish fire, but firefighters should pay attention to the corrosiveness of water dissolved in caustic soda.
5. Can be packed in iron drums or other sealed containers. Packaging containers should comply with relevant regulations, and barrel caps should be sealed.
The above is the storage of liquid potassium hydroxide. Keep these points in mind to prevent product damage, economic losses, and even accidents. I hope you can read the above articles carefully, so that products can be stored in a safe environment.
