55 Cup no phase change material: interlayer water flask
Know user “wild strains of” dismantling the very popular 55-Cup, found the thermal conductivity principle is very simple, did not use the official claim of micron-order phase change material, at best, can only be regarded as interlayer water flask.
55-degree Cup is LKK lkk design group company to launch the product, called rapid cooling Cup shake pour in boiling water 1 minute cup water temperature can drop to about 55 degrees. Some netizens speculate, 55-degree Cup uses a “sodium acetate trihydrate, sodium hydrogen phosphate 1 12 water and gelatin” thermally conductive material, such as, principle and warm baby and the like.
Officials have denied, claiming that this is unscrupulous sellers imitation approach taken by 55-Cup, genuine 55-degree Cup with thermal layer, μm and three layers of insulation layer phase change materials. Heat conduction layer of stainless steel, hot water heat mug can be passed quickly to the micron level in phase change materials, through rapid endothermic phase change material for micron to achieve cooling function.
“The wild bacteria” found in the dismantling, 55 degrees-volume 280ml, internal has over 270ml of bile with orange suspension suspension individually heated temperatures from room temperature soaring to 100 degrees Celsius, there is no warming slow curve, heating process of suspended particles in solid-liquid transition did not occur, meaning that there is no phase change.
In addition, around 0.05g per 100ml suspensions through centrifugation to extract solid, the solid is heated to 400 degrees Celsius without breaking up, is considered to be Micron particles, do not dissolve in water, 1N HCL and 1N NaOH and acetone.
Therefore, “the wild bacteria” concluded that 55-Cup heat storage are the most primitive of the water used by specific heat thermal energy storage, in the so-called phase changes will take place in the course of using, “the wild strains” also said that 55-Cup the cooling materials cheaper than cheap sodium acetate trihydrate.
Addition information displayed for United States Northwest University Dr of users “into Chu d” also said, 55 degrees Cup actually is a inside with sandwich water of mug, sandwich of cold water achieved fast cooling, temperature changes calculation process for (20+90)/2=55, outer insulation material let cooling curve appeared a more long of platform period, warming effect also compared pit dad, temperature changes calculation process for (50+20)/2=35.
We can see from the official page, 55-degree Cup into the boiling water and shake for 1 minutes, water temperatures can drop to 55 degrees Celsius, pour in water at room temperature, shake 1 minute at room temperature may go up to 37 degrees Celsius or so, and if it continues to pour in boiling water, half an hour before it can be dropped to 55 degrees Celsius, directly into the water at room temperature is not accounted for.
