A distilled water machine refers to pure water prepared by a distillation method. The water can be distilled once and several times. After one-time distillation of the water, the non-volatile components remain in the vessel and are removed. The volatile components enter the initial fraction of distilled water, usually only the middle portion of the fraction, about 60%. To obtain purer water, an alkaline potassium permanganate solution can be added to the distilled water to remove organic matter and carbon dioxide; a non-volatile acid is added to make the ammonia a non-volatile ammonium salt. Since the glass contains a small amount of water-soluble components, it is necessary to use a quartz distillation vessel for two or more distillations to obtain very pure water, and the obtained pure water should be stored in a quartz or silver container.

First, the working principle of distilled water machine

The production is to boil the source water and then evaporate and condense it. It takes a lot of heat and the cost is not too low. Other hot evaporated substances in the source water used to make distilled water are condensed into distilled water with the formation of distilled water. For example, phenols, benzene compounds, and even vaporizable mercury that are harmful to health. In order to obtain pure water or ultrapure water, it is necessary to add other pure means after two or three times of distillation.

Second, the application of distilled water machine

In life, when it is generally related to machines and electrical appliances, the role of distilled water is mainly that it is not electrically conductive, ensuring stable operation of the machine and prolonging the service life of the appliance. In the pharmaceutical industry, the role of distilled water is due to hypotonic effects. Rinse the surgical wound with distilled water, so that the tumor cells that may remain in the wound surface swell, rupture, necrosis, loss of activity, and prevent the tumor from growing on the wound. Some of the chemical experiments in schools use distilled water, which uses distilled water without electrolytes, no free ions, or no impurities. You need specific analysis of the specific problem to see if it uses its non-conducting properties, or whether it is hypotonic, or if there are no other ions, and no chemical reaction will occur.

Third, the characteristics of the distilled water machine

An alkaline potassium permanganate solution can be added to the primary distilled water to remove organic matter and carbon dioxide; a non-volatile acid (sulfuric acid or phosphoric acid) is added to make the ammonia a non-volatile ammonium salt. Since the glass contains a small amount of water-soluble components, it is necessary to use a quartz distillation vessel for two or more distillations to obtain very pure water, and the obtained pure water should be stored in a quartz or silver container.
