Distilled water is pure water in which impurities and suspended substances are removed by distillation. Its main principle is to evaporate water vapor and then condense it according to the boiling point difference of substances to obtain high-purity water.
1, the basic principle of distilled water:
Distilled water is the preparation process of pure water by using the boiling point difference of substances. In the distiller, water is heated to the boiling point, and water molecules are converted into steam and enter the distillation device, and then cooled by the condenser, finally forming pure liquid water.
2, the preparation process of distilled water:
First, the water to be treated is added into the still and heated to the boiling point. With heating, water begins to be converted into steam and enters the distillation unit. Then, the water vapor passes through the condenser, cooled and re-condensed into liquid. In the process of condensation, impurities and suspended substances are not easy to be converted into water vapor because of their relatively high boiling points, so they are separated and finally pure distilled water is obtained.
3. Application fields of distilled water:
Distilled water is widely used in many fields, including laboratories, pharmaceuticals, electronics, food, beverages and cosmetics. In the laboratory, distilled water is often used to prepare solutions, wash glassware, dilute and cool during experiments. In pharmaceutical industry, distilled water is an important raw material in pharmaceutical process, which is used to prepare drugs and washing equipment.
In the electronic industry, distilled water is often used to clean semiconductor devices and electronic components to ensure the purity of their surfaces. In food and beverage industry, distilled water is often used for purification, washing and preparation in food processing and beverage production. In the cosmetic industry, distilled water is one of the important ingredients for preparing cosmetics and skin care products.
Distilled water has the characteristics of high purity and low dissolved solid content, and is widely used in situations where high-purity water quality is needed in various industries. Distilled water plays an important role in both scientific research in the laboratory and the treatment of purified water in industrial production, which provides strong support for the development of all walks of life.
