Deaerating & Mixing
Deaerating is to remove dissolved gases like oxygen from liquids. Mixing refers to combining different substances into uniform mixtures.
In the field of raw materials in the chemical industry, mixing mainly means stirring solid with solid or liquid. Mixing can combine with the deaerating for uniformity and purity of mixtures.
Importance of Deaerating and Mixing
01
Mixing provides various inseparable and uniform mixtures, such as emulsions, suspensions, etc. Mixing multiple raw substances can obtain different materials with various properties, which is important in basic material processing in the chemical industry.
02
Deaerating can remove bubbles generated during the mixing, reducing the interference of dissolved gases on the mixture for high purity.
Methods of Deaerating and Mixing Techniques
Mixing can be achieved by stirring and grinding equipment like dispersers. Especially planetary mixers that are widely suitable for solid-liquid mixing in various viscosities.
When solid-liquid mixing involves particle refinement, homogenizers get solid particles extremely small, evenly distributed, and suspended in the liquid. Generally, vacuum deaerators use centrifugal force under vacuum negative pressure to achieve deaeration.
FAQs of Deaerating & Mixing
What industries benefit from deaerating and mixing?
As an important part of raw material processing, deaerating and mixing is suitable for the chemical industry, battery material, new energy, ink and coatings, food, pharmaceuticals, cosmetics, and other production industries.
What are the types of mixers used in deaerating and mixing?
Mixing: high-speed disperser, nano-disperser.
Emulsification: horizontal emulsifier, vertical emulsifier, high-pressure homogenizer.
Homogenization: planetary mixer, high-efficiency homogenizer, twin-screw homogenizer.
Deaerating: vacuum deaerator.
Are there any challenges in deaerating and mixing?
The mixing and homogenization technology currently on the market makes it hard to achieve continuous, effective, and stable production, especially in battery cathode and anode materials. With long-term operation, the homogenizing equipment is prone to mixture residue, resulting in material loss and insufficient uniform mixing. Batch intermittent production equipment, planetary mixers, and high-efficiency homogenizers are commonly used in the industry. LONGLY twin-screw continuous homogenization system helps solve it, allowing production stability and continuity.
