Increase knowledge! Is the phone waterproof bag waterproof!

Many people who don’t know about waterproof bags feel that they are not waterproof. They don’t dare to carry their mobile phones when entering the water. They can’t record the beautiful moments. I don’t believe it when I don’t touch the waterproof bags. After all, thousands of mobile phones are not daring to try. Water, I believe most people are the same as me. So is the phone waterproof bag waterproof? The first time I came into contact with the mobile phone waterproof bag was given when I bought a swimsuit. I put a paper towel to test it for half an hour. When I was playing in the water, I put the phone in it, and I was terrified for fear of accidents. After all, sea water is different from tap water. The water pressure in the sea is also different. Fortunately, there is no water leakage, but after all, it was sent, and it was discarded after using it once. The waterproof quality of the mobile phone waterproof bag is average. 2017 is the year to truly understand waterproof bags. I joined a company that specializes in waterproof bags. Only then did I know that so many people are already using waterproof bags, and the export volume is still very large. Customers with good sales will purchase in one year. Nearly 1 million.　　 Next, based on my own understanding, I will share my knowledge of waterproof mobile phone bags.　　 1. What kind of waterproof bag is better?　　 There are generally two kinds of waterproof bags on the market: PVC and TPU. Relatively speaking, TPU material will be softer and feel better, and of course the price will be a little more expensive than PVC. PVC waterproof bag: The thickness of the previous is basically 0.3MM, but the HOME button above Iphone7 is not a push-type can not be used, so now 0.2MM, 0.15MM is more common, general mobile phone use there is no problem TPU waterproof bag: There are not so many restrictions on TPU, 0.4MM Iphone7 can be used, if you buy it for your own use, it is recommended to buy TPU, it is not too expensive, the TPU material is degradable within 3 years, and it is environmentally friendly .　　2. Which waterproof performance of zipper type waterproof bag or clip type is better? What impressed me was that I went rafting again. I took a company’s clip-style waterproof bag. As a result, the tour guide said that the waterproof effect should be better without zippers. In the eyes of most people, several zippers should be more waterproof than clips. The effect is good, but it is not. We have tested it by a professional organization. The clip type can pass IPX8 30 meters, but the zipper type is uncertain. Most of them can only be underwater 3 meters for a short time, and rarely can be underwater. It is 30 meters waterproof, so it is recommended to use the clip style, the price will be a little more expensive than the zipper, but you can rest assured.　　 3. Why can't I take pictures underwater with the waterproof bag?　　 Nowadays mobile phones are all capacitive screens. There is water pressure underwater, so the mobile phone cannot be operated, but there is no problem taking pictures and videos. Press the volume button.　　 4. Is there a waterproof bag that can be used with side buttons?　　 The newly launched panoramic model on the market has no frame on the side, which breaks the traditional craftsmanship. It has a beautiful appearance and a very good feel to use. It is well received by the public.　　 5. Can the inflatable waterproof bag really float? It can float. If there is air in the waterproof bag, the buoyancy will be better. It can float a mobile phone of more than 100 grams. However, there is a drawback of inflating the air. After a period of time, the air will slowly leak out, just like a balloon. It will collapse after a while, so be careful when using inflatable waterproof bags. If you sink into the sea, you will lose more than you gain.
