What is the typical temperature in a high-temperature workshop?
What is a high temperature workshop? The literal meaning is a factory workshop with a higher working temperature. So what is the temperature in a high-temperature workshop generally? It is generally considered that the temperature inside the workshop is 2°C or more higher than the calculated outdoor summer design ventilation temperature, which is considered a high-temperature workshop. The calculated outdoor summer ventilation temperature is determined based on the average monthly average temperature at 14 o’clock of the hottest month officially recorded by the local meteorological station in the past ten years. This temperature actually fluctuates. Summer temperatures have been relatively high in the past 10 years. The calculated outdoor summer ventilation temperature is likely to exceed 32°C, and the temperature in the high-temperature workshop may also exceed 35°C.
What is the softening temperature of epoxy carbon fiber tube?
The most commonly used carbon fiber tubes at present are thermosetting carbon fiber tubes, of which epoxy resin is more common, so we use data to understand the softening temperature of epoxy resin carbon fiber tubes. The epoxy value n of epoxy resin is generally between 0 and 5. According to the relative molecular weight, epoxy resin can be divided into various types, and the corresponding softening temperatures of epoxy resin carbon fiber tubes are also different.
Generally, the average epoxy n of low-molecular-weight epoxy resin is less than 2, and the softening point is lower than 50°C, also known as soft epoxy resin; the epoxy value n of medium-molecular-weight epoxy resin is between 2 and 5. time, the softening point is between 50 and 95°C; for high molecular weight epoxy resins with an epoxy value n greater than 5, the softening point is above 100°C. The higher the epoxy value, the higher the softening temperature. This is also true for epoxy resin carbon fiber pipes. Its softening temperature is generally considered to exceed 80°C.
Can carbon fiber tubes be used in high-temperature workshops for a long time?
To see whether the high-temperature workshop can be used for carbon fiber pipes for a long time, you can compare the temperature of the high-temperature workshop with the softening temperature of epoxy resin carbon fiber pipes. The former is 35°C and the latter is 80°C. The latter is significantly higher than the former, so we can draw a conclusion. , High-temperature workshops can use epoxy resin carbon fiber tubes for a long time.
This was a theoretical situation at that time. In actual use, if the temperature inside the high-temperature workshop is out of control, or an open flame occurs, and the temperature approaches or even exceeds 80°C, the epoxy resin carbon fiber tube may be softened by high-temperature baking and lose its mechanical properties. Naturally, It cannot be used anymore, so the final judgment must be made based on the actual situation.
