1. Moisture absorption and caking.
Double layer packaging bag is used for potassium hydroxide packaging. If the joint is not fast enough or tight enough, the product can easily absorb the moisture in the packaging bag and affect its quality. Therefore, changing the original single seam to double seam requires the packaging personnel to check and clamp the seam, which isolates the air to a great extent and greatly reduces the occurrence of seal looseness caused by caking.
2. Affected by temperature.
The temperature of potassium hydroxide is determined by the cooling water flow of the drum and the rotating speed of the drum. The circulating water volume, circulating water temperature, whether the nozzle in the barrel is blocked and whether the barrel is scaling directly affect the product temperature and seriously affect the uniformity of mechanical blanking temperature. After cleaning the nozzle, clean the scale in the bucket and increase the circulating water. Reduce the temperature of potassium hydroxide from 63c-66c to 58c. The caking phenomenon can be reduced by reducing the blanking temperature.
Potassium hydroxide has many bonding reasons closely related to environment and temperature. Special attention should be paid to these two aspects. In order to avoid affecting our use, many factors should be considered in daily protection and storage, and each link should not be too hasty. After all, its quality is also one of the basic factors affecting the use efficiency.
Precautions for storage and use of potassium hydroxide sealing operation operators must receive special training and strictly abide by the operating rules. It is recommended that operators wear hooded electric air supply filter dust mask, rubber acid and alkali resistant clothing and rubber acid and alkali resistant gloves. Keep away from combustibles and combustibles. Avoid dust. Avoid contact with acids.
Be careful when handling potassium hydroxide to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may leave harmful substances. When diluting the prepared solution, alkali shall be added to the water to avoid boiling and splashing. Potassium hydroxide is stored in a cool, dry and well ventilated warehouse. Keep away from fire and heat sources. The humidity in the warehouse shall not exceed 85%. The package must be sealed and moisture-proof. It shall be stored separately from combustible materials and acids and shall not be mixed. The storage area shall be equipped with suitable materials to prevent leakage.
