The water in heating boilers and heaters is not ordinary tap water, but chemically treated softened water. Like circulating water, heating water must not be used for bathing. The water entering the heating pipeline is treated softened water, and its cost is much higher than tap water, and the cost per ton is about 10 yuan. In order to ensure the safe operation of the boiler and heating system, the heating department should add anti-corrosion, anti-scaling and softening water treatment agent to the system water to remove the rust scale in the boiler and prevent the boiler and heating system from being blocked and exploded. This medicine is very corrosive because its ingredients contain alkaline substances. Once the human skin is in contact, it will produce strong corrosion, damage the skin and be harmful to health.

The tap water and sodium ions are exchanged to obtain softened water. With the constant exchange of sodium ions, softened water is produced. When sodium ion fails, it needs to be washed with salt water and then with tap water until it is qualified, so that sodium ion can recover its performance. It is repeatedly emphasized that softened water is always used in boilers. Although softened water has no total hardness, sodium ions increase and the salt content of water increases.

Demineralized water is not salt water in the general sense. It is not salty, contains neither iodine nor trace elements such as calcium and magnesium needed by human body, and can never be drunk. But also contains preservatives, such as caustic soda, tannin extract, sodium phosphate and so on. Washing vegetables, bathing and washing clothes with such water is harmful to people's skin and health.

Supplement:

Prevent users from putting hot water privately. The heating company should throw in the odor agent.

During the heating period, some users often let out the water in the heating privately in order to make their heating hotter, or to wash clothes and flush toilets. In order to stop this kind of water and energy consumption, the relevant person in charge of the heating company of Yinchuan Thermal Power Plant told reporters yesterday that the company will add irritating chemicals to the heating water in the near future.

Thermal power plant heating company is the largest supplier in Yinchuan.

The heating area of heating enterprises accounts for one-seventh of the total urban heating. Manager Wen of the company told reporters that during the heating period, some users will put water in the heating to make the heating hotter, and some users even use the washing water in the heating to wash clothes or flush toilets. The illegal release of hot water by users has caused great losses to heating enterprises. On the one hand, heating enterprises need to consume more water; On the other hand, it also increases the heat loss.

In order to solve this problem, the heating company of Yinchuan Thermal Power Plant will add a smelly medicine called "Water Saving King" to the hot water recently. Manager Wen told the reporter that the product was specially developed to prevent some users from connecting hot water to the heater privately. Although the smell of water-saving king is harmless to human body, its pungent smell will make people reluctant to smell more, so it will also deter users from putting hot water. The reporter learned that the water-saving king has anti-scaling and anti-corrosion components and has no adverse effects on the pipeline system. In addition, the preparation does not pollute the environment.

It is understood that the heating company of Yinchuan Thermal Power Plant will add water-saving king to the heating water as early as next week. As for the specific time, they will not inform users in advance. (Yan Yan)
