Brief introduction of the difference between ultrasonic homogenization and micro-jet homogenization technology
Among various high-energy homogenization methods, ultrasonic homogenization technology and high-pressure micro-jet homogenization technology are the main methods. This article briefly explains the comprehensive comparison between micro-jet technology and ultrasonic technology. Ultrasound is a process that uses high-frequency sound energy to generate cavitation (bubble expansion and implosion) through propagation in a solution to break particles. The inherent characteristics of ultrasonic technology lead to the following disadvantages:
1. The strong cavitation phenomenon will peel off the metal particles on the ultrasonic probe and contaminate the material, causing difficulties in the downstream process and leaving hidden safety hazards in the product.
2. The design of ultrasonic homogenization cannot be used for continuous homogenization.
3. Ultrasonic homogenization technology cannot achieve production-level capacity amplification.
4. It is difficult to control the material temperature during ultrasonic homogenization.
5. Since the ultrasonic energy is directly related to the distance of the probe, the intensity of each position is not uniform during homogenization.
The high-pressure micro-jet technology uses a booster pump to pass the solution through the uniquely designed (Y-type and Z-type) extremely small pores of the diamond interactive cavity under an ultra-high pressure of hundreds of Mpa to form a supersonic micro jet. In the process, pure physical effects such as high-speed collisions, mutual shearing and impacts are generated, which nanometerizes the liquid droplets and particles in the solution, and then significantly changes the functionality of the material to meet the solubility and stability of various industries. High-end requirements for emulsification, transparency and other indicators. High-pressure micro-jet homogenizers are commonly used in pharmaceuticals (nanoemulsions, liposomes, fat emulsions, microspheres, etc.), biotechnology (cell crushing and extraction), cosmetics (refined transdermal absorption), fine chemicals (inkjet, additives, etc.) Dispersion), health care products (component refinement suspension) nano new material dispersion (graphene exfoliation, nano oxide loose clusters) and other fields. The obvious advantages are:
1. The uniquely designed diamond microporous homogeneous channel enhances the degree of wear resistance under high pressure and avoids the risk of metal particles peeling off.
2. The high-pressure micro-jet homogenizer has inlet and outlet ports to achieve continuous homogenization.
3. The microfluidic technology has mature production equipment, and the same microchannels are used for production from small-scale trials, but the number of channels is increased in parallel, so it is easier for users to enlarge subsequent production capacity, saving R&D time and costs.
4. The micro-jet technology can cooperate with the material heat exchanger to achieve effective temperature control, and the American Genizer company can also provide a temperature-controlled diamond interactive cavity.
5. Micro-jet technology with constant pressure and uniquely designed interactive cavity can ensure that each part of the material is uniformly homogeneous, so the reproducibility is very good.
