How to judge the quality of caustic soda tablets

When purchasing soda ash, users pay great attention to its quality. High quality products not only have a long service life, but also have good performance, which can be reflected in the application process of different industries. Moreover, it is often used as a raw material, and if its quality is poor, it will inevitably affect the quality of the products produced. This illustrates the importance of good quality. Here we teach you how to judge its quality,

At this point, if the color is found to be incorrect or there is a black and white area, it may contain other impurities. It is normal for ordinary caustic soda to have no blemishes and occasionally a little gray or red, which does not affect the quality.
2. Pinch it with your hand and it will instantly transform from a sheet to a granule. Take some and put it in your hand. Drip a few drops of water on your hand, and you will feel the heat emanating from the upstream of your hand. This is because it has a high temperature when in contact with water. On the contrary, the quality of the explanation is not very good.
3.The shelf life of caustic soda tablets is generally one year. If left for too long, the color will become dark and black. Also, it depends on the thickness and size, the thinner the better, the smaller the better, and it is easier to dissolve when used.
