Many people think that scale only affects the beauty of faucets; When boiling water precipitates, scale will not affect the taste; The scale in the thermos can't be seen anyway, so it won't have any effect ... but in fact:

1, scale is harmful to human health: the impact of scale on human health can never be ignored. Scale can easily cause gastrointestinal digestive and absorption dysfunction and constipation, and increase the incidence of gastritis and various stones. Dental calculus and periodontitis are often caused by scale; Can kill people. Legionella is hidden in the scale and there is still no vaccine to prevent it.

2, and scale is insoluble in water, which is relative. After the water is heated, part of the precipitate will dissolve, thus bringing the heavy metal ions that form the precipitate back to the water, which makes the content of heavy metal ions in the water exceed the requirements of sanitary standards and is harmful to human health. For example, calcium carbonate and magnesium carbonate are easy to form stones when deposited in large quantities in the human body.

3. The expert made a chemical analysis on the boiling water scale stored in a 5-pound thermos for 18 days, and found that it contained many harmful metal substances, namely, 0.034 mg of cadmium, 0.0 mg of lead, 24 mg of iron, 0.2 mg of arsenic1mg and 0.44 mg of mercury. This shows that even drinking water that meets the hygienic standard can be deposited and accumulated in water after being stored in a thermos, which is harmful to human health. If you drink water that does not meet the hygiene standards, the potential health hazards will be more serious. Therefore, scale must be removed regularly.

4. When sour plum soup, beer and other acidic liquids are replaced by vessels with scale, some heavy metal elements precipitated in the scale will react chemically and dissolve in water or other liquids again. Long-term intake of a small amount in the body will cause pathological changes and dysfunction of the digestive, nervous, respiratory and hematopoietic systems, which will cause serious harm to human health. So don't underestimate this scale.

5. The scale suspended in water will precipitate in the body after being drunk by us, which will easily lead to an increase in the incidence of diseases such as kidney calculi's disease and urethral calculi.

6. Scale is the real culprit of common oral diseases such as tartar and periodontitis. If you can't cure oral diseases for many times, you might as well start with scaling.

7. Legionella is hidden in the scale, and there is no vaccine to prevent it. In China, 2,000 to 3,000 people die from this pathogen every year.

8, scale hides more hidden dangers: washing your face and bathing with water containing scale will form calcium-magnesium soap, which is as thick as chewing gum and sticks to your face and skin, making it difficult to remove dirt. If dirt is not washed, it will block the openings of skin glands, form embolism, affect normal metabolism, and make the skin shrink and age prematurely. The regular cleaning of scale in automobile water tank system is often ignored. After the scale is deposited in the water tank, the water temperature is too high, the output power is reduced, and the engine is seriously locked and damaged.

Electric tiger in energy-saving home;

Scale reduces the thermal conductivity of household appliances and steals more than 22% of our electricity;

Scale not only causes serious energy waste, but also easily leads to local corrosion of household appliances, kettles, aluminum pot, thermos bottles, household heating stoves, hotel boilers and self-heating heaters. , leading to perforation scrap. What's more, electrical appliances explode due to uneven heating, and the consequences are unimaginable.

Long-term use of drinking water will produce a lot of scale, which will not only block the outlet and consume energy, but also produce a high heat surface inside, which will melt the human body and cause combustion or explosion.

In the active area where the scale of electric kettle is produced, a large amount of scale will be produced every time water is boiled. Thick scale accumulation will inevitably increase the time of boiling water and consume a lot of electricity. Excessive scale deposition will also damage the electric kettle and shorten its service life.

The fault of steam iron is often caused by scale, which blocks the nozzle, hinders heating and affects the use effect.

The inner container of thermos bottle is very fragile, and the scale inside is the cradle of bacteria.

Long-term use of water heaters will produce a lot of scale, which will prolong the boiling time by 1-2 times or even longer, thus wasting at least 3 times of energy. A large amount of scale will block the water outlet, which is inconvenient to use, and it is more likely that the internal pressure of the water heater will rise rapidly, thus causing an explosion, causing economic losses and even personal safety hazards.

After using the humidifier for a week or two, a lot of scale will adhere to the inner wall of the nozzle and water container. After a long time, there will be ignition inside the humidifier, which will lead to failure and shorten the service life.

The scale in the flushing water tank will block the flushing port, resulting in poor flushing effect and waste of water.

There are a lot of water stains on tiles and mirrors, which are difficult to wipe off with towels or other utensils.

The scale of shower nozzle makes the water flow smaller, even without water, which makes life inconvenient and wastes resources.

The scale of self-heating wall-hung boiler will affect the heating effect, cause energy waste, seriously block the waterway, and even cause compressor damage, boiler explosion and other problems.

Scale in pressure cooker will breed, which will lead to the aging of rubber band and the blockage of air outlet, which will easily lead to explosion after heating at high temperature.

Coffee used for a long time is easy to scale, which affects its service life and breeds bacteria.

It is difficult to remove the scale from drinking utensils, which is harmful to health.

Solar energy stores water for a long time, and the inner wall of the water tank often scales, which reduces the heating degree and affects the water quality. Bathing will do harm to the human body.

Bathtub scale is difficult to clean, hygiene is not in place, and it is easy to get skin diseases.

The hot water kettle reduces the thermal conductivity and affects the usability.

Scaling of engine water tank in automobile circulating water system is the most common problem. Scaling will limit the flow of antifreeze in the cooling system, reduce heat dissipation, lead to overheating of the engine and even cause engine damage.
