Fault analysis of differential scanning calorimeter
Differential scanning calorimeter mainly measures the relationship between temperature and heat flux related to the internal thermal transformation of materials, with a wide range of applications, especially in material research and development, performance testing, and quality control. The curve recorded by differential scanning calorimeter is called DSC curve, which takes the rate of heat absorption or release of the sample, that is, the heat flow rate dH/dt (unit millijoules/second) as the vertical axis and temperature T or time t as the horizontal axis. It can determine various thermodynamic and kinetic parameters, such as specific heat capacity, reaction heat, transformation heat, phase diagram, reaction rate, crystallization rate, polymer crystallinity, sample purity, etc. This method has a wide temperature range (-175~725 ℃), high resolution, and requires minimal sample usage. So, speaking of which, the editor found that many people encounter some problems and malfunctions when using differential scanning calorimeter. How should we solve these problems when we encounter them?
Differential scanning calorimeter ignition failure
Firstly, check the position of the fuse, which is usually located at the back of the machine. Check if the ignition heads on the top covers of the three pillars under the oxygen bomb are rusted. If they are rusted, it will cause poor contact. Use sandpaper to remove the rust. Check if the ignition wire inside the oxygen bomb is securely fastened, if the cotton thread is connected, and if the oxygen is fully charged. Failure to do so will result in ignition or failure.
Differential scanning calorimeter oxygen bomb leakage
The main purpose is to inspect the damage of the sealing rings. There are four types of sealing rings on the machine, and the testing personnel learned from the commissioning and installation personnel about the disassembly, replacement, and positioning of the four types of sealing rings. In addition, maintenance of the differential scanning calorimeter should pay attention to the following aspects: * First, environmental hygiene should be protected. The machine cover should be opened to keep the machine dry. When the temperature is low, the water inside the machine should be kept from freezing. When not using the oxygen bomb, it should be opened and stored to keep it dry.
If the ignition wire burns out, the reason for ignition failure is generally at the connection between the ignition battery and the oxygen bomb or the oxygen bomb itself. The possible reasons for this are:
There is a layer of oxide on the surface of the ignition battery, which makes the contact resistance too high. The oxygen bomb cover has a layer of oxide, which makes the contact resistance too high. The elasticity of the connection spring of the ignition battery is not enough. The spark plate and the electrode inside the oxygen bomb are short circuited, and the ignition wire is not tightly tied. The connection of the oxygen bomb itself is not good
