What are the categories of waterproof waist bag and how to choose waterproof waist bag?
Friends who play outdoor sports know that outdoor waterproof is very important, especially for wading activities, rainy season, crossing and vacation, mobile phones, wallets, bank cards and licenses. When you go to Maldives, you need to be relieved and happy, right? Be prepared to prevent accidental losses. Taking good care of your valuables is the top priority!
Waterproof and lightweight waist bag is the best one for water protection. So what are the waterproof waist bags? How to identify fake waterproof and full waterproof waist bag? It is worth discussing with you.
Classification of waterproof waist bag:
From the fabric:
防水腰包,主要聊聊防水级别达到ipx6以上的,现在市面上有很多种类,如果说单纯从面料上说,主要分为两大类,一大类是PVC夹网布,一类是tpu贴合布。这里暂且不将市面上防雨水的防水腰包包括进来,毕竟那不是真防水,其防水级别最多是ipx3级。
pvc夹网布主要是绦纶网格,然后两面贴着PVC材料。
Tpu贴合布呢?就是中间是尼龙材料,因丹数不同而强度不同,两边呢,就是tpu材料,但是厚度不同。有些贴合布,只是单面贴合。所以这防水强度上还是有差异的。
从袋口开合上分:
如果说防水腰包的差异从袋口开合上来说,主要分两大类,一是卷口的/束口的开口腰包,另一种是拉链开口的腰包。
卷口束口这个开口方式呢,是比较传统的方式,已经有几十年的历史了,其实工艺上并不复杂,制作相对简单啊,设计不复杂,然后使用上也挺方便。但缺点也很明显,就是,泡在水中久了之后就会松开,容易进水,渗水。还有就是嗯,卷口要折叠使用上比较麻烦,比较拖泥带水,不是非常方便与简练。卷口的一般用到魔术贴,将袋口粘紧,魔术贴一般都是pvc的,在冰冷环境与过热的环境下,会发生一定的使用风险。
As for the zipper opening, the early waterproof zipper is not good either. The early waterproof zipper is only a simple PVC film added to the traditional sewing zipper. However, the zipper opening does not solve the problem of waterproof. In the process of use, water will be immersed from the zipper gap. Therefore, the development of waterproof zipper has been relatively slow. The waterproof bag made of waterproof zipper in the early stage can only prevent rain, that is, below moderate and light rain, so it is far from the requirements of outdoor use.
With the progress of zipper technology revolution, YKK and tizip have conquered the real air tight zipper. Coupled with the progress of domestic air tight zipper technology in recent years, the waterproof zipper has better met the requirements of various harsh environments in the polar region. It even meets the waterproof requirements of diving level. If you want to meet the requirements of deep diving, the structure of the zipper is completely different from the feeling of use. For example, YKK's air tight zipper is engaged by double gears, so as to achieve the purpose of physical isolation of water and gas. However, it is difficult for ordinary people to pull, and the use experience is slightly poor. However, it is relatively easy to pull the waterproof zipper. Its structure is single gear, and the depth used in diving is strictly limited. Therefore, you can't have both fish and bear's paw! According to the market situation, the cost of waterproof zipper is not low. The expensive one is 300 yuan and the general one is about 50 yuan.
Therefore, waterproof waist bags with good waterproof zippers are expensive. All waterproof waist bags have now become a new category.
Appearance and appearance:
Now many people in the market boast that they are waterproof waist bags. In fact, they are not really waterproof. They just prevent water splashing. Everyone should see clearly!
From the perspective of appearance classification, the waterproof waist bag that can be truly waterproof can be divided into two types: no design and design flow. The former directly only seeks function but not beauty, while the latter needs function and appearance.
市面上潜水级的防水腰包还是比较少的,所谓的潜水机防水腰包,必须是亲密拿量才可以达到的,传统的卷口束口方式的防水腰包是达不到的,因为经过测试,卷口方式的,在水中泡半个小时基本就开始漏气了,如果转口的压力压强不足够阻挡水的压力,那水就会去沿着卷口渗水入体之内。
