Aldehyde removal and deodorization device

Li Lan of Beijing Institute of Technology has a master's thesis to share with you, "Study on the characteristics of air pollutants in passenger cars", which mentioned.

Formaldehyde, benzene and other substances in the car can cause dizziness, drowsiness and other phenomena, which can easily lead to bronchitis, rhinitis and even lung cancer for a long time.

The new car smells like a process, not that it will take two or three days.

So many friends will choose some methods to come to in addition to formaldehyde, such as activated carbon bags. Of course, this thing is quite good in 1 and 200 yuan. It is skillful to use it, otherwise, it is better not to use it.

Li Na of South China University of Technology shared her master's thesis "Preparation of Negative Ion/Activated Carbon Composite and Its Application in in addition to formaldehyde", which read.

The adsorption and desorption properties of activated carbon composites were tested: when the activated carbon composites were saturated, formaldehyde was adsorbed into the activated carbon.

It won't be too hot at 60℃ after saturation, will it? Desorption is carried out in an oven at 60℃, and the adsorption capacity can reach more than 82% after five repetitions.

To put it bluntly, the activated carbon bag absorbs formaldehyde, takes it outside to dry, discharges it and puts it back, so it can be reused. It's the same as a sponge. Squeeze it, and the water will come out, and then it can absorb water again.

If the charcoal bag is put in the car and absorbs formaldehyde, but it just stops in the open air, it must be at 60℃ and released again, so pay attention.

This is a charcoal bag. Take it out and put it out regularly. Everyone needs to pay attention to whether to buy or recommend. A few hundred dollars to buy an air purifier is also a way.

Wu Yong et al. published a paper in Modern Preventive Medicine, "Comparative Study on the Purification Effects of Several Air Purification Technologies on Indoor Formaldehyde Pollution".

The above experiments show that the formaldehyde removal rates of formaldehyde purifier, photocatalyst and activated carbon in 24 hours are 88%, 76.5% and 43.2% respectively, and the air purifier only takes 12 hours, and the highest formaldehyde removal rate is 9 1.74%.

Pay attention to the principle of air purifier when buying.

Some air purifiers are also sterilized in addition to PM2.5, which is very impressive. Even PM0.0 1, but this one is not from in addition to formaldehyde. Don't buy it wrong, you should have a look.

The second is to put a film on the car glass.

And Yang published a paper "Research Progress on Mechanism and Prevention of Skin Photoaging Caused by Ultraviolet" in Medical Review, which mentioned.

About 90% of the damage to exposed skin is caused by ultraviolet rays, which is what we call "ultraviolet radiation". Long-term exposure to ultraviolet rays will make the skin age faster, become fragile, dry, slack and even get sick.

Many friends' wives or our female fans, this thing is more concerned and necessary.

According to the data of Pacific Auto Network, the ultraviolet blocking rate of the front and rear windows of Sagitar model 20 1 1 is less than 52%. 20 1 1 corolla (picture | configuration | inquiry) ultraviolet blocking rate shall not exceed 45%.

Although many new cars now use windows with an ultraviolet blocking rate of about 99%, some car companies that cut corners still use low blocking rate.

Or 99, right? Part of it is, part of it is not, and we don't know which part is not, so something very strange happened.

Sticking a regular, advanced, qualified, reliable and cost-effective car film can not only isolate ultraviolet rays, but also contribute to heat insulation, privacy and driving safety.

The third suggestion you should consider is: reverse image.

The Insight Report on Mainstream Configuration in China released by Easy Car Research Institute shows that after 20 16 to 20 17 years, the compliance rate of reversing radar is about 85%, while the compliance rate of reversing image is only about 65%.

That is to say, about 20% of cars only have reversing radar, no reversing image, and some cars have neither.

Only when the reversing radar is reversing, there is a great possibility that it is a relatively high side of the road, with a child squatting behind it and a puppy suddenly coming ... it will not recognize or call the police.

Besides, we can't stand it. If we don't recognize it once, we're screwed, right?

There are also passing battery cars, aren't there? The aunts and grandmothers who walked backwards and clapped their hands before and after, all panicked anyway.

IIHS, the American Highway Safety Insurance Association, also conducted an experiment: more than 100 volunteers were asked to back up and then put a child dummy behind the car. It is found that reversing radar is easier to hit dummy than reversing image.

Therefore, if the reversing radar alone can't handle some situations, you need to take a look at the reversing image, so it is recommended to spend money to install the reversing image. Choose what is clear and useful and can be seen clearly during the day and night.

Another trick is: the angle of the probe is better. If it is peaceful, like a cat's eye hanging on the door, the camera will be dirty when it rains.

It's not like reaching under the car to wipe the lens when driving, is it? Choose a good angle, choose a good location, and find an old master to install it.

Child safety seat installation

The fourth one is: If there are children in the car, I recommend the child safety seat? No matter how expensive it is, you should consider it. You must buy a new one.

Wu of Hunan University has a master's thesis to share with you, "Research on the Structure and Safety of Intelligent Child Safety Seats", which says so.

There is a big physiological gap between children and adults, and the proportion of children's heads is relatively high, just like the cartoons of big-headed sons.

However, the child's skull and neck are soft and easily deformed in accidents. Moreover, the elasticity of the chest and spine is greater than that of adults, and these parts have greater displacement ability, which is called "easy dislocation" in the local dialect.

Children can't directly use the safety system of adults, so they need special seats for children. For example: adults wear seat belts, which just grab the chest and shoulders, right?

If the child wears a seat belt and goes straight to le neck, it is better not to wear a seat belt, right?

And buy safety seats, second-hand safety seats should be cautious. This thing actually has a service life. If this life span is exceeded, the guarantee effect may be affected. What do you mean? For example: Britax, the safety seat life of infants (under 4 years old) is 6 years; The best service life of Er Qiao is 5 to 7 years; Gray's safety seat life is usually 7 to 10 years. I also asked wheelton, a domestic brand, that the normal service life is about 10 years.

Second-hand seats were originally used by others for 3 or 4 years. Counting the time of leaving the factory and changing hands, it is very likely that they have exceeded the best service life in our hands. The point is that I don't know how long it took them. Nobody wrote this thing when they sold it to me. You can also look at the mileage when you buy a used car. What can I write on the seat? I don't want to take the risk myself = the price difference between new seats and second-hand seats is not as much as I thought. Let's see if the second-hand seats are cheap. How about a new discount? So I suggest using the year and date of production to check and see. Some even sell there, which I don't think is good.
