Outdoor sports drinking water is essential, and it is very necessary to prepare a quality, clean water bottle.
The material of sports kettles is pure aluminum. As a large country of aluminum products, China has a complete range of products.
Another factor is the wall thickness of the kettle. The wall thickness of the sports kettle is 0.7mm.
As it is difficult for general consumers to distinguish the thickness of sports kettles,
some manufacturers will cut down the cost by opportunistically reducing the thickness of kettles to save materials.
Some manufacturers even reduce the thickness of sports kettles to 0.5mm.
An intuitive feeling to judge the thickness of a kettle's wall is that if you hold it in your hand, the weight of a kettle with a thinner wall will be lighter.
If the sports kettle is made of aluminum with low purity, or with thick wall, it will be easy to dent, break or even burst due to collision or falling.
Generally, the higher the purity of aluminum, the higher the wall thickness, the better the strength and toughness of the sports kettle,
and the stronger the ability to resist collision and impact.Of course, the better the quality, the higher the cost and price.
As is known to all, excessive intake of aluminum can cause great harm to human health.
The coating in sports water bottles solves the problem of isolation:
the water, juice, milk, coffee and other beverages in sports water bottles are separated from the aluminum pot body.
The coating in the kettle is more than 20% resin, about 1% additive, the rest are solvents.
Sports bottle quality is good or bad, is the most important determinants of safe and reliable, the first is internal coating raw material itself is safe,
will not bring harm to human health, moreover is the internal coating in the inside of the kettle spraying quality whether uniform coating,
adhesive and firm, and the thickness of the necessary, to ensure that the drinks and the reliability of the aluminum pot body isolation.
Under the pressure of fierce export competition, in order to reduce costs and increase competitiveness,
most domestic manufacturers currently choose cheap coating materials, and due to their size and strength,
their equipment and technology are difficult to guarantee the coating quality of sports water bottles.
The internal coating of sports kettles must meet the hygienic requirements of food grade. However, due to the lack of supervision and inspection,
the internal coating of sports kettles products in China, except for a few large manufacturers,
has almost all the problems of various degrees that flood the market with cheap products.
The lid of a sports kettle is made up of the lid and washer.In the process of use, the general sports kettle is not too hard due to its quality,
and the gasket will stick to the spout part due to too tight pressure for a long time, cold or hot air temperature.
It may even break off the cover, causing troubles to use.
A good sports kettle adopts the secondary injection molding technology, which directly integrates the washer and lid,
which not only achieves a good sealing effect, but also fundamentally eliminates the possibility of separation.
