Be wary of cut corners and shoddy water bottles in the market!(Four)

Because the editor has been in the water bottles industry for more than 10 years and has encountered many examples of water glasses, the topic of this article is relatively long. I hope you can continue to pay attention to reading.

F-type water cup, stainless steel thermos cup.Many friends like to use stainless steel thermos. In addition to being durable, the main reason is that this water cup can keep warm for a long time. However, some consumers found that the thermal insulation performance of the water cup declined rapidly after using it for a short time after purchase. In addition to the quality of workmanship, there are more cases of cheating. In the process of producing thermos cups, vacuuming is a very important process. The standard operation of this process is continuous vacuuming at a high temperature of 600°C for 4 hours.

However, in order to reduce production costs and improve production efficiency, many factories will shorten the general vacuuming time. The thermal insulation effect of the water cup produced in this way is still acceptable when it is first used. However, since the air in the interlayer of the water cup is not completely evacuated, after repeated use, the high temperature conduction of the water in the water cup will cause the residual air in the interlayer to expand. As the air expands, the interlayer changes from a semi-vacuum to a non-vacuum, so it is no longer insulated.

The G water cup is also a general term, referring to the paint sprayed on the surface of the water cup.Since water cups are used for drinking water, it is required that the materials for producing water cups and the materials for auxiliary processing of water cups must be food grade. At present, most of the water cups on the market have been sprayed on the surface, which not only has a beautiful appearance, but also has a certain protective effect. Now most water cup factories use food-grade water-based paint, which is not only safe for the human body but also more environmentally friendly.But water-based paint also has certain disadvantages.

Due to the adhesion of the hardness tester, it is easy for consumers to cause the paint to fall off during use, which brings a very bad consumer experience to consumers. This situation is also one of the most complaints about water cups, and another situation is the problem of non-insulation. However, in order to reduce this situation and reduce production costs, some factories choose to use oil-based paint.This kind of paint not only has a high content of heavy metals, but some serious ones also contain radioactive substances. Long-term use of this type of especially sprayed water cup is more harmful to people's health, and the cost of oil-based paint is lower than that of water-based paint, so it will be used by some unscrupulous merchants.
