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,
1.From a color perspective, regardless of whether the caustic soda is a pure white solid, those with higher purity will not contain impurities. 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.
4.Many manufacturers use other substances to impersonate. Commonly used stinky alkali. Odor alkali is a mixture of other alkalis after waste production is completed. Although it is alkaline, it is very weak. Many manufacturers use it to impersonate other chemicals, which requires special attention from buyers. For many consumers, due to a lack of professional knowledge about caustic soda, their purchasing is blind, and they only listen to the salesperson's deception, causing many potential dangers.
Some consumers may not be able to judge the quality of caustic soda tablets, but they can use them when buying after learning. It should be noted that you must compare prices from three different sources and not just search for one product. If you have any needs, please contact us promptly.
