What is the standard for insulation
Standard is 100 degrees of boiling water after 24 hours, 70 degrees is normal, if you want to see if thermos insulation, after filling water pot if skin is very hot, it is not warm.
China's main vacuum keep-warm glass quality inspection standards GB/T 11416-11416 "daily baowenrongqi, QB/T 2332-1997" stainless steel vacuum heat preservation container, GB 9684-1988 "standard of stainless steel tableware containers health", GB/T11681-1989 "hygienic standards for stainless steel tableware containers analysis method" and so on, these standards are clear glass insulation insulation efficiency of container, bad breath, impact resistance, capacity, dump test, hand and ring joint fastness, hot water leakage, assembling safety and labeling program, and stainless steel vacuum insulation insulation efficiency of container, capacity, impact resistance, bad breath, rubber parts of the installation of water resistance, hand the fastness, sealing, stainless steel tank requirement (lead, cadmium), the assembly of the cork inosculation and labeling program. A, insulation efficiency: insulation efficiency is the core of the heat preservation container. Second, capacity: the capacity of heat preservation container enough goods, on the one hand, relationship can directly associated with guaranteed temperature on the other hand, namely the same caliber, the bigger the capacity requirements of the higher temperature. So the capacity of heat preservation container positive bias and negative deviation are not too large.
Three, hot water leakage: the quality of vacuum cup involves the use of safe, and affects the use of environment beautiful. To test temperature quality whether there is a serious problem, as long as the mention vacuum cup full of water, if the cup of bravery and cup shell will leak out between the hot water, whether it's large amount or quantity is little, suggests that this glass quality can't cross the border. Four, impact resistance: vacuum cup quality directly influences the quality of the service life of vacuum cup. In the process of the use of the products, hard to avoid has a party, if the product accessories, avoid vibration of materials or spare parts accuracy is not enough, the inside
And there will be a gap between the shell, using the shaking and knock against could cause displacement of asbestos mat, crack of small tail affect product thermal insulation performance, serious when can cause inside crack and even broken. Five, the logo: normal temperature has the relevant national standards, namely, product name, capacity, diameter, name and address of manufacturer, using the standard number, use method and matters needing attention in use are clearly marked. Is the heat preservation container more than five common standards of quality inspection.
