How to identify unqualified plastic water cups “at a glance”? (four)

Friends open the smelly plastic water cup, take out the desiccant, and then wash it with clean water (normal temperature water is best, do not use high temperature water) plus vegetable detergent. After repeated cleaning twice, wipe or dry and then smell whether there is any smell in the cup. If there is an obvious pungent smell, it means that the material of the cup is faulty.

Some friends would like to share with me whether these methods are also suitable for drinking glasses of other materials, such as stainless steel drinking glasses, glass drinking glasses, etc. Usually the odor is mainly emitted from the accessories made of plastic material. In view of the fact that stainless steel water cups and glass water cups are not very consistent, when there is a chance later, the editor will sort out how to identify qualified stainless steel thermos cups and qualified glass water cups.

Next, the editor will share other aspects of the water cup and tell you how to pay attention.

Some water cup factories may have problems with orders due to delivery, quality and other issues. In this case, the factory will have inventory, and some factories have a backlog of inventory for more than 10 years. There will also be some factories that will process the overstocked inventory at a very low price to companies that specialize in recycling inventory for capital recovery. For example, a well-known e-commerce platform known for its low prices, the reason why many products are low in price is that most of them are defective or seriously overstocked.

How to judge that the purchased water cup is a serious backlog, we have to judge the silicone part on the filling cup. Some water cup lids will be covered with silicone, and some are covered by the body of the cup. If you can't find the silicone on the surface, friends can take out the silicone ring that is used as a false seal to check. The most obvious way for the backlog of water cups for a long time is the phenomenon of silica gel slag.

This must be a long-term backlog, and the white silica gel turns yellow and dark. As for pulling the silicone sealing ring, it will break, which is the most serious. Whether it is silicone slag or yellow and dark water cups, editor recommends not to use them.Long-term inventory due to temperature and humidity weather.Although some hard plastics such as PC, AS, etc. cannot be seen from the surface, in fact, the performance and quality of the water cup have declined.
