Cycling is now a popular outdoor travel or fitness choice for many people. With a lot of sweat, it is necessary to replenish water at any time. The single car kettle sold on the market is divided into two categories: plastic pot and metal kettle. And plastic pot can be divided into soft and hard glue. Metal pots also have aluminum and stainless steel pots.
Soft glue, a white opaque bicycle kettle, which accounts for a large market share, is made from it. If you come to the bottom of the kettle and face the sky, you will find some symbols with the material description printed. If there is no such sign, a blank one, it is recommended to call 12315 immediately to report fake and inferior goods... Generally, there is a small triangle sign at the bottom of the plastic container, and there is an Arabic number in the middle, from 1 to 7. picture
Generally, soft glue water bottles are made of HDPE of "2" or LDPE of "4"“ The plastic No. 2 is relatively stable, and can be heat resistant to 120 ℃, but the plastic "4" cannot be directly loaded with water, and the maximum water temperature cannot exceed 80 ℃, otherwise, plastic preparations that cannot be decomposed by human body will be released.
Hard glue, its bottom number is "7."“ 7 "is PC code, because it is transparent and fall resistant, it is widely used in making water bottles, water cups, milk bottles.
Pure aluminum, aluminum in the acid liquid (juice, soda, etc.) will produce harmful chemicals, long-term drinking aluminum pot may lead to memory loss, mental decline, etc. On the other hand, pure aluminum is relatively soft, most afraid of bumps, and it will be uneven when it falls. Appearance is not a big problem, most of all, the coating is torn, lost the original protection function, which is equal to the white lap.
In contrast, stainless steel kettle has no coating trouble, and can be made into double layer insulation. Double layer besides the heat preservation also has the advantage that the hot water does not hot, do not think that summer does not drink hot water, sometimes in the front of the village behind the shop, the experience brought by hot water is far better than cold water. In case of emergency, single layer stainless steel pot can be directly set on fire to burn water, which can not be done by other water bottles. Now many domestic stainless steel water bottles are very good quality, but also more resistant to collision. However, stainless steel water bottles are heavier and filled with water. Generally, plastic water bottles on bicycles may not bear. It is recommended to replace them with aluminum alloy water bottles.
