jet gas-liquid glass static mixer is fully sealed system, gas evolution is close to "0".Radial and heart-shaped structure, better eddy current effect, smaller bubbles, etc.
Compared with the traditional tank type dynamic stirring mixing and pipeline static mixer, the micro mixer has the advantages of large specific surface area, high mass and heat transfer efficiency, high safety, and small amplification effect. In the process of reaction amplification and optimization, the microchannel mixer has higher reproducibility, stability, and high efficiency. In the case of blocking conditions, due to the special sealing and packing design, compared with the traditional The pipeline static mixer is easier to clean the dirt and replace the mixed filler. As a special form of the microreactor, the micromixer can handle many processes that cannot be handled by other equipment in the continuous flow process.
Micromixer application fields: chemical reaction process with strong exothermic, emulsifier, liposome, pigment and dyestuff, cosmetics and other industries.
The principle of the point-jet micro-mixer: the gas is dispersed 360 degrees by the small flow channel of the liquid channel, and the bubbles are smaller. The radial branch has a strengthened heart-shaped structure, which makes the vortex stronger and produces smaller bubbles. The flow channel structure has a good effect on the small flow of gas and liquid.
Jet structure gas-liquid glass micro mixer: 0.05-0.1mm depth and width, good gas dispersion effect. Flow range: 0.01-10ml/min. The glass material gas-liquid micro mixer is more conducive to gas-liquid observation, with a maximum pressure resistance of 7MPA.
Use of static micromixer:
Before using the micromixer, you must fully understand the compatibility of the reagents, including the compatibility of the sealing packing, joints, and the mixer module with the reagents. When the sealing packing and the mixer module are obviously incompatible with the reagents, please do not work, otherwise it will be damaged Micro mixer; when the sealing packing is not compatible with the reagent, please replace the sealing packing material in the micro mixer to meet the requirements of the working conditions; when the joint is not compatible with the reagent requirements, the operation process needs to observe whether there is leakage and the leakage time , Replace the connector in time. From the perspective of safety in use, this operation is not recommended.
Static micromixer cleaning:
When the experimental process is over, please clean the micromixer in time to avoid residual process fluid in the mixer. High-concentration process fluid residue may block the mixer; the order of cleaning solvents is reaction solvent, water, and ethanol. When the mixer is clogged, please disassemble the mixer, immerse it in the cleaning solvent, and clean it with ultrasonic for 0.5-1 hours; at the same time, you can use a soft brush dipped in the cleaning solvent to gently wipe the clogged part of the mixer.
Warning:
Please use it within the specified rated pressure range. If the supplied pressure exceeds 20MPa, the micromixer will be damaged or deformed, causing malfunctions.
Please use it within the specified rated temperature difference range. If the supplied temperature difference exceeds 300K, the micromixer will be damaged or deformed, causing malfunctions.
When feeding solids, please note that the diameter of the solid particles should be less than 10% of the equivalent diameter, and the solid content of the reagent should be less than 5%, otherwise the micromixer may be blocked.
When using the device, do not hit it hard or drop it from a high place. Even if the appearance is not damaged, it may cause malfunction due to damage to the internal parts.
