How many classification methods are there for home textiles?

The principle of home textile separation process is to use the connection between the solubility of the supercritical fluid and its density, that is, the use of pressure and temperature on the influence of the solubility of the supercritical fluid and carried out, in the supercritical state, the supercritical extraction equipment will supercritical fluid and the substance to be separated, so that it selectively extracts the polarity, boiling point and molecular weight components in turn.

Application and characteristics of supercritical extraction equipment
The effect of temperature on the solubility of supercritical fluid is complex, under a certain pressure, the volatility of the extract is added with the increase of temperature, which adds the concentration of the extract in the supercritical gas phase, and then adds the extraction amount; On the other hand, with the increase of temperature, the density of supercritical fluids decreases, resulting in a decrease in solubility and extraction, so we must pay attention to these two aspects.

The particle size of the material can affect the extraction recovery rate, reduce the particle size of the material, add the touch area of solids and solvents, and then increase the extraction speed, but if the particle size is too small or too fine, it will not only seriously block the screen, but also form an extractor outlet filter blockage, of course, the extract obtained by corresponding to each pressure scale cannot be single, but can manipulate the conditions to get the best share of the mixed ingredients, and then with the help of decompression, The method of heating makes the supercritical fluid into a general gas, and the extracted substance is completely or basically precipitated, and then the purpose of separation and purification is achieved, so the extraction process of supercritical extraction equipment is composed of extraction and separation process.
