The solar water heater has high heat absorption efficiency, and if it does not use water for a long time in the case of summer eyes, it will keep the water tank in a state of high temperature and high pressure for a long time, which will promote the aging of the sealing ring, accelerate the aging and shrinkage of the insulation material - polyurethane, and sometimes cause the exhaust to be unsmooth, and the pressure is too large and the water tank will swell, and will form scale, shorten the life of the water tank.
Therefore, if it is not used for a long time, it should often be put hot water on cold water, or a cover should be placed on the heater to block the sun, or the vacuum tube can be removed and stored at home, and then installed when it is reused (this maintenance method is generally not used, but because of its potential safety hazards, the user can not disassemble it privately, if necessary, you can contact the local dealer to coordinate the disassembly).

Sex chopsticks hide three major harms:
DU impairs respiratory function: the process of making chopsticks must be fumigated with internal sulfur, and SO2 will be released when exposed to heat during use, eroding the mucosa of the respiratory tract;
Damage to digestive function: disposable chopsticks are bleached with hydrogen peroxide during the production process, hydrogen peroxide has strong corrosiveness, causing corrosion to the mouth, esophagus and even gastrointestinal tract; The use of talcum powder in the grinding process will cause people to suffer from gallstones if they are not clean, and they will slowly accumulate in the human body.

The most useful advice for you is not to use white wood and bamboo chopsticks!
The smell is because the chopsticks have two sulfur oxide residues during processing, and when they are put into hot water, they come out.

Such chopsticks can't be solved by putting hot water! Or, you don't want to be too lazy to order takeout but don't even want to wash your chopsticks. Let's use everyday chopsticks!
If you find it inconvenient to go to work, buy plastic! For example, 'Sen. Brave. Hua's disposable chopsticks, just remember not to buy wooden ones! Don't buy bamboo!
Take responsibility for your own health!
