When using caustic soda, the user found that there are problems with caking that affect normal use, but it was not clear what caused this. Two possible causes of caustic soda clotting are summarized below.
1.Temperature of caustic Soda
The temperature of caustic soda is determined by the flow rate of cooling water and the rotating speed of machine. The amount of circulating water, the temperature circulating water, Whether the sprinkler is blocked and scale formation in the rotary drum of a caustic soda machine directly affect the temperature of caustic soda and the uniformity of the charging temperature of a caustic soda machine. After cleaning the sprinkler head，cleaning the scale formation, increasing circulating water, decreasing the temperature of caustic soda flakes from 65℃ to 58℃， the caking phenomenon can be alleviated.
2.Caustic soda caking due to moisture Absorption
The laminar bag is a double-layer packing bag. If the seam is not fast enough or the seam is not tight enough, the laminar in the bag is easy to absorb moisture and affect its quality. So the original single seam was changed into a double seam, and the packaging personnel were required to inspect the processes of entrainment and suture, so as to achieve large air isolation and greatly reduce the problem of caking caused by loose sealing.
There is no direct relation between the quality and the caustic soda caking. However, if the caking happens, it will affect the normal use and the effect of use. Therefore, the manufacturer should pay special attention to the production and the use of users.
