The chemical formula of potassium hydroxide is Koh, which is a strong base. Like other chemicals, it has a "shelf life" and its "shelf life" is short. This statement comes from its chemical properties because it can absorb water and carbon dioxide in the air to produce potassium carbonate. Therefore, once it is stored improperly, if it is not sealed for storage, it is easy to deteriorate. After deterioration, the alkalinity is weakened, and its composition has changed, the original chemical reaction will also change. Therefore, the original function can not be brought into play.
What is the treatment of expired potassium hydroxide? Is it the same as our domestic garbage? The answer is No. In fact, the main method of expiration treatment is recycling. 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. Recycling expired can not only protect the environment, save energy and drive the stable and sustainable development of social benefits, but also improve the benefits of enterprises and companies and save costs.
However, companies operating expired recycling need recycling qualifications and certificates, because potassium hydroxide is toxic and corrosive and belongs to one of the national managed products. If you want to engage in the recycling industry, you must also obtain relevant permission. Undocumented companies are not allowed to recycle. In addition, the recycling price is affected by many factors, so the recycling price is not fixed.
