Water, the importance of life, can be imagined. In this society where water pollution is becoming more and more serious, everyone is also very concerned about the water and pure water safety issues of pure water! Below, Xiaobian will do a brief introduction to pure water for everyone!
Pure water refers to H2O without impurities. What is pure water ? From an academic point of view, pure water, also known as high-purity water, refers to water with extremely high chemical purity. Its main applications are in the fields of biology, chemistry, metallurgy, aerospace, electric power, etc. High, so the most common application is the electronics industry. For example, pure water used in power systems requires low levels of impurities to reach the "microgram / liter" level. In the production of pure water, the indicators specified in the water quality standards should be based on the production process of electronic (microelectronic) components (or materials) (such as the size of the particulate matter generally believed to cause damage to the circuit performance is its line width) 1/5-1/10), but due to the complexity of microelectronics technology and the factors affecting product quality, there is still no complete water quality standard for process production from a process test. However, in recent years, electronic water standards have been revised, and many breakthroughs and developments in the field of high-purity water analysis, the continuous application of new instruments and new analytical methods have created conditions for the development of water-making technology.
So what is pure water? The so-called pure water means that its water quality is pure, does not contain any harmful substances and bacteria, such as organic pollutants, inorganic salts, any additives and various impurities, effectively avoiding the invasion of various bacteria into the human body, and its advantage is that it can be effectively and safely given The human body replenishes water and has a strong solubility. Therefore, it has a strong affinity with human cells and promotes metabolism. It is water produced by deep treatment using ion exchange, reverse osmosis, fine filtration and other appropriate physical processing methods. Under normal circumstances, pure water is used in the production process, only 50%-75% of the source water is used, that is to say, 1 kg of tap water or groundwater can only produce about 0.4 kg of pure water, while the remaining 0.6 kg or so Water cannot be used as drinking water and can only be used for other purposes.
After reading the introduction of Xiaobian’s knowledge about what kind of water is pure water , is there a general understanding of water? I hope everyone can save water and protect water resources.
