1. In the palette pot, the refined oxalic acid needs to be precipitated for 2 hours before the palette starts.

2. During the precipitation process, the temperature should be maintained at 450-500 degrees. Accelerate impurity precipitation.

3. Take a small amount of refined oxalic acid to the sample plate and send it to the laboratory if the color is milky white.

4. Adjust the equipment dipping hopper to a height that can keep the drum in contact with the refined oxalic acid.

How to Enhance the Stability of Refined Oxalic Acid

1. The higher the viscosity of the dispersion medium, the higher the stability of the refined oxalic acid.

2. Adding solid powder can stabilize the refined oxalic acid. Solid powders depend on the wettability of oil and water to solid powders and will remain at the water-oil interface.

3. The charge of the droplets has a significant effect on the stability of oxalic acid. The more oxalic acid ions adsorbed on the droplets, the more charged the droplets are, the more stable the emulsion system is, and the greater the ability to prevent the droplets from coalescing. The droplets are generally charged.

The stability of refined oxalic acid should be enhanced. Attention should be paid to the addition of stabilizers which do not react with the components of oxalic acid as a supplement, and a little charge can be added to maintain the stability of ion movement.

Do you know what to pay attention to when storing and transporting refined oxalic acid?

1. Equipped with refined oxalic acid varieties and quantity of fire fighting equipment.

2. Keep the container sealed. Refined oxalic acid should be stored separately from oxidant. Prevent direct sunlight.

3. Store in a cool, ventilated warehouse. Keep away from fire and heat sources.

4. It is forbidden to use inflammable machinery and tools.

5. Refined oxalic acid filling should control the flow rate to prevent electrostatic accumulation. Handling should be light loading and unloading to prevent damage to packaging and containers.
