Comment on in addition to formaldehyde's father.
I found my father's evaluation on the internet, and formaldehyde floated over. The machine with five cents and more than 300 yuan agreed time, and the machine was already in place two days ago. Close ahead of time, the data of 24 measurements is very low. Fortunately, the video for customizing soft clothes in the whole house at home is still relatively expensive. More relieved.
The test was scheduled for June 6, but I sent the instrument in advance from my last home, so I tested it in advance.
1, 12 Room is sealed before testing. At 7 o'clock in the morning, the central air conditioner was all turned on to 30 degrees stuffy, and I went home from work to test;
2. Only the living room and study room did not exceed the TVOC value measured yesterday, but the formaldehyde in all rooms did not exceed the standard. Then I measured the master bedroom again after work today, and the result was the same as yesterday. Personally, I think it is more accurate.
I won't elaborate on the operation process of the instrument. On the whole, it's not bad. The whole process is smooth and the operation is simple and convenient. I believe that the instruments evaluated by Dad can be seen in the official WeChat account, and if necessary, Dad's lab.
Correct method of removing formaldehyde with activated carbon
In the air purification industry, coconut shell activated carbon is the most active activated carbon and is famous for its strong adsorption capacity. The unit price of coconut shell activated carbon is expensive, and the cost of selecting coconut shell activated carbon as an air filter is about 4 times higher. Coconut shells are pyrolyzed and converted into activated carbon at high temperature and certain pressure. In this activation process, huge surface area and complex pore structure are gradually formed, and the so-called adsorption process is carried out in these pores and surfaces. The size of pores in activated carbon can selectively adsorb adsorbents, because macromolecules cannot enter the pores of activated carbon which are smaller than other pores. Activated carbon is a hydrophobic adsorbent made of carbonaceous materials through high temperature carbonization and activation. Activated carbon contains a large number of micropores and has a huge surface area, which can effectively remove chromaticity and odor, and can remove most organic pollutants and some inorganic substances, including some toxic heavy metals, from secondary effluent.
Activated carbon material is amorphous carbon obtained by processing, which has a large specific surface area and good adsorption capacity for gas, inorganic or organic substances in solution and colloidal particles. Activated carbon materials are widely used in sewage treatment, air pollution prevention and control and other fields. The correct way to use it is to first disperse the purchased activated carbon package indoors as much as possible. After standing at 12, take it to the outdoor ventilated place to dry several times. Only when activated carbon is used repeatedly can it play its due in addition to formaldehyde role. The way of removing formaldehyde by activated carbon is similar to that of sponge, which is a treatment process from indoor to outdoor.
For the new house in addition to formaldehyde, activated carbon has a good effect, but it can only play an auxiliary role. Indoor in addition to formaldehyde is solved by real-time effective ventilation, which is faster, safer and healthier!
Without a remedy to remove formaldehyde, the gas of formaldehyde will not disappear soon. In addition to formaldehyde's father's evaluation method has been sorted out for everyone. In fact, it takes a long time to remove formaldehyde, so you can't move in immediately after the renovation of the new house. Vacant ventilation for more than 3 months is good for your health. It is a long process to master the correct method of activated carbon in addition to formaldehyde, effectively in addition to formaldehyde and eliminate formaldehyde gas.
