Mașina de dispersie poate produce bule în timpul procesului de lucru, iar cauzele pot include următoarele aspecte:

Caracteristicile lichidului: The presence of dissolved gases or bubbles in the liquid, such as water containing dissolved air. When the liquid is subjected to intense agitation and shear forces during high-speed agitation or dispersion, the dissolved gas will escape from the liquid to form bubbles.

Solid additives: If solid additives, such as solid pigments or powders, are added during the dispersion process, these solid particles may violently collide and stir with the liquid, resulting in the formation of bubbles.

Mixer design: The design and shape of the mixer may also have an impact on the formation of bubbles. Improper mixer design or shape may cause the liquid to mix unevenly and form bubbles.

Stirring speed: Stirring too fast may introduce a lot of air into the liquid, resulting in the formation of bubbles.

Solution measure
In order to reduce or avoid the formation of bubbles, the following measures can be taken:

Reduce dissolved gas in the liquid: Stir or heat the liquid well in advance to encourage the gas to escape the liquid.

Control the mixing speed: Select the appropriate mixing speed according to the specific situation to avoid the introduction of bubbles caused by too fast mixing.

Reasonable blender design: Choose the right blender shape and size to ensure uniform mixing and avoid dead corners and uneven flow of liquid.

Use the appropriate dispersant: Adding the right amount of dispersant can help reduce aggregation between particles and reduce the production of bubbles.

Pre-treatment of solid additives: Pre-treatment of solid pigments or powders, such as wet grinding or suspension treatment, can reduce the formation of bubbles.

It is necessary to comprehensively consider and adjust the operating parameters according to the specific process and material characteristics to reduce or control the bubble generation in the dispersion machine.
