What is the temperature control method of the reactor?
The reaction kettle used for temperature control has a large capacity and a thick wall, so it is a controlled object with a large heat capacity and a long pure lag time. As the reaction progresses, the heat transfer coefficient of each heat transfer medium changes nonlinearly, and the The changes of various external environments are relatively sensitive; in addition, the gain of the reaction process will change greatly, and even the direction of gain change is different; and as the reaction p...

New energy vehicle high and low temperature test system
With the popularity of new energy vehicles, high and low temperature tests have become a factor that car owners need to consider when purchasing new energy vehicles. Since the environment in which new energy vehicles are used is harsher, it is also very important to conduct high and low temperature tests on vehicles. At present, there are two common high and low temperature test methods for new energy vehicles on the market: one is to conduct high and low temperature tests through laboratory ...

Recrystallization temperature and influencing factors?
Recrystallization is the process of recrystallizing crystals from a solution or melt after they are dissolved in a solvent or melted. Recrystallization can purify impure substances or separate mixed salts from each other. Among them it is the result of physicochemical action. Solid material can be purified by recrystallization. Recrystallization of some metals or alloys can refine the grains, or change the crystallization, thereby changing its properties. The general process of recrystalli...

Rapid temperature change test chamber temperature control instructions
The selection of the humidity range of the rapid temperature change test chamber should be noted that the corresponding temperature range should be indicated after the humidity index or the dew point temperature should be given. Because relative humidity is directly related to temperature, for the same moisture content, the higher the temperature, the lower the relative humidity. To achieve high temperature and high humidity, it is only necessary to spray water vapor or atomized water droplet...
