General standards for quality inspection of thermal insulation containers:
1. Insulation efficiency: Insulation efficiency is the core indicator of insulation containers.
2. Capacity: On the one hand, the capacity of the thermal insulation container is related to the ability to hold enough items, on the other hand it is directly related to the holding temperature, that is, the same caliber, the larger the capacity, the higher the holding temperature is required. Therefore, neither the positive deviation nor the negative deviation of the capacity of the heat preservation container can be too large.
3. Hot water leakage: The quality of the vacuum flask involves safety in use and affects the aesthetics of the use environment. To check whether there is a serious problem with the quality of the thermos cup, just lift the thermos cup filled with water. If hot water leaks between the cup bladder and the cup shell, whether it is large or small, it means that the quality of the cup cannot pass.
4. Impact resistance: The high quality of the vacuum flask directly affects the service life of the vacuum flask. In the process of using the product, bumps and bumps are inevitable. If the material used in the product accessories is poor in shock absorption or the accuracy of the accessories is not enough, the bottle
There will be a gap between the shell and the shell. Shaking and bumping during use may cause the displacement of the asbestos pad, the cracks of the small tail, and the impact of the product's insulation performance. In severe cases, it may also cause cracks or even breakage of the bottle.
5. identification: the formal insulation cups have relevant national standards, that is, the product name, capacity, caliber, manufacturer name and site, the standard number used, the method of use and the precautions in use are clearly marked.
