First, the cosmetics dispersion cosmetics want to penetrate deeper into the skin layer, let the skin absorb better, play the role and effectiveness of drugs. The extraction of the essence is very important. In order to better extract the essence of the drug and the micronization of the particles, the production cost is saved, and the components are dispersed and emulsified. Ultrasonic emulsification is the most ideal method. By ultrasonic dispersion, fine particles of oil such as wax and paraffin emulsified or lotion can be dispersed without using an emulsifier. Paraffin particles dispersed in water can be up to 1um in diameter.
Second, the alcoholization of wine - urging Chen technical chemical changes is also the formation of acid, is the main controlling factor of wine. In order to further esterify the acid, the ester is involved in the association of ethanol and water. The wine that has just been shipped contains sterols, which have a spicy taste. It takes a long time to resolve. This slow change is called alcoholization. Ultrasonic treatment with a power of 1.6KW and a frequency of 17.5-22KHZ for 5-10 minutes can shorten the ripening time of wine by 1/3 to 1/2.
Third, extraction of biological nano (chemical synthesis)
In the ultrasonic chemical reaction, the key role is the cavitation effect of sound waves. During the irradiation of the ultrasonic waves, the formation of cavitation bubbles, growth and collapse will occur in the liquid. When the cavitation bubble collapses, a strong pressure pulse is created that produces many unique properties, such as producing high temperatures of up to 5000K and pressures of greater than 200 MPa. This is similar to the principle of ultrasonic cleaning. This is also the source of energy for ultrasonic chemical synthesis, which can be used to synthesize nanoparticles on the surface of some special powders.
Fourth, the role of ultrasonic pharmacy 1, the preparation of vaccines - cells or germs by means of ultrasonic dispersion to kill them, and then made a vaccine by appropriate methods;
2. Dispersion of pharmaceutical substances for injection - Mixing phospholipids with cholesterol by mixing with an appropriate method in an aqueous solution, and dispersing by ultrasound, smaller particles can be obtained for intravenous injection.
3. Preparation of Suspension - A solid drug is dispersed in an aqueous solution containing a surfactant under ultrasonic cavitation and vigorous agitation to form an oral or intravenous suspension of about 1 um. Examples are "intravenous camptothecin suspension", "liver contrast agent", "barium sulfate suspension".
4, herbal extracts - the use of ultrasonic dispersion to destroy plant tissue, accelerate the solvent penetration of tissue, improve the extraction rate of active ingredients of Chinese herbal medicine. For example, all alkaloids in the bark of the cinchona can be invaded by the general method for more than 5 hours, and the ultrasonic dispersion can be completed in half an hour.
Main purpose of ultrasonic cell pulverizer in medical use
In addition to the cleaning effect of ultrasonic waves, ultrasonic pulverization in medical use is more widely used. There are many factors affecting the smashing and the technical requirements are high. This is undeniable. Ultrasound in medical pharmacy mainly has the following uses:
