Last Saturday, Nanjing (Beijing store) again ushered in rain, rain shoes became a lot of public travel equipment. On the Internet, there is a hot note that as long as the candle oil is applied to the surface of shoes, it can be made into a pair of waterproof shoes. Reporters in accordance with the online post, brought a pair of old shoes experiment, found that the part of the wax oil can really waterproof, but this kind of waterproof effect really good?

　　 Shoes coated with candle oil and waterproof shoes. ?

In this online hot micro-blog, we first need to prepare a lighted candle, cotton swab and a pair of leather shoes. Next, apply the candle oil evenly to the upper surface with cotton swabs. In addition, scrape off the extra candle oil after finishing. After cleaning, blow the wax oil off with electric blowing, so that the waterproofing process is finished. Finally, the water is washed up and the water is not stained, so that "my mother no longer needs to worry that my shoes will get wet!"

Recently, the reporter took an old pair of yellow casual outdoor shoes to do some experiments. According to the steps in the post, put the candle oil on the candles and put the candle oil on the upper. Seemingly simple steps, but it is not easy to spread evenly, and small cotton swabs can not touch much candle oil. When the reporter smeared and observed, he found that there were always tiny places that were not smeared, and some of them were thick and thin. During the next waxing process, the reporter found that compared with other parts that had not been smeared with candle oil, the oiling part had darkened.

When all the steps were completed, the reporter put the shoes under the tap, and after that, he was still wet. And other parts that are not oiled are already wet.

　　 Professional: Waterproof time is short.

"Wax is a hydrophobic material and has some effect on waterproofing." Zhang, a doctoral student in the Department of materials science and engineering, Nanjing University, told reporters, "especially when the waxing process is uniform and dense, the waterproofing effect should be good." Moreover, Mr. Zhang explained that because wax is relatively stable in chemical properties, wax and shoes can not react, so the negative impact on the surface of shoes should be small.

Can it be waterproof? How does it last? Mr. Zhang told reporters, "only water in a short time". It turns out that after long use, the viscosity of wax and vamp on shoes will be reduced, and surface wax may appear cracks, fine lines and micro stripes, and then fall off.

What is the principle of professional outdoor waterproof shoes on the market? The reporter consulted many outdoor shoe store owners in Zhujianglu Road, although most shopkeepers said they had heard of the production of such waterproof shoes, but many shopkeepers said, "shoe waterproof generally refers to the increase of friction on the sole rather than the upper." According to the introduction, professional mountaineering waterproof shoes are made of artificial leather mixed animal leather, but some types of waterproof shoes have poor air permeability, so when wearing waterproof shoes, mountaineers usually wear multiple pairs of shoes to wear them.
