The chemical formula of potassium hydroxide is Koh, which is a strong base. Like other chemicals, there is a "shelf life" and it has a shorter "shelf life". This is due to its chemical properties, because it can absorb water and carbon dioxide in the air and produce potassium carbonate. Therefore, once the storage is improper, if it is not sealed for storage, it is easy to deteriorate. After metamorphism, the alkalinity is weakened, and its composition has changed, so the original chemical reaction will change accordingly. Therefore, the original function can not be played.
What's the treatment of expired potassium hydroxide? Is it the same as our garbage? The answer is No. In fact, the overdue treatment is mainly recycling. Because although it has expired, the product of its deterioration is potassium carbonate, which is also a basic chemical and can be used for other purposes. The overdue recycling can not only protect the environment, save energy, drive the stable and sustainable development of social benefits, but also improve the efficiency of enterprises and save costs. However, companies operating overdue recycling need to have recycling qualification and certificates. Because potassium hydroxide is toxic and corrosive, it is one of the national pipe products.
If you want to engage in the recycling industry, you need to obtain relevant permission. Unlicensed companies are not allowed to recycle. In addition, the recycling price is affected by many factors, so the recycling price is not fixed.
