Temperature-pressure control system for dipping pot

Abstract

The invention discloses a temperature-pressure control system for a dipping pot. The temperature-pressure control system for the dipping pot comprises a central processing unit (CPU) controller. A control end of the CPU controller is connected with a temperature sensor. The temperature sensor is connected with the dipping pot through an electric heater. A vacuum control end of the CPU controller is connected with a vacuum controller. The vacuum controller is connected with a vacuum mouth of the dipping pot through a vacuum pump. The CPU controller is connected with a pressure end of the dipping pot through a pressure sensor. A display end of the CPU controller is also connected with a light-emitting diode (LED) displayer. The CPU controller can be used for detecting vacuum degrees, temperature and pressure parameters of the dipping pot through the pressure sensor and the temperature sensor. Detective results can be displayed through the LED displayer. When the detective results are not fit with demands, the CPU controller can be used for adjusting the temperature and pressure of the digging pot through the vacuum pump and the electric heater. The temperature-pressure control system for the dipping pot has the advantages of being accurate to control the temperature, the vacuum degrees and the pressure.

Description

technical field [0001] The invention belongs to the technical field of ceramic fiber impregnation, and in particular relates to a temperature and pressure control system for an impregnation tank. Background technique [0002] Ceramic fiber is a kind of fibrous lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical shock resistance, so it is used in aviation, aerospace, metallurgy, chemical industry, petroleum, Ceramics, glass, electronics and other industries have been widely used. However, at present, the biggest disadvantage of the ceramic fiber prepared by the PIP method is that the precursor will release many small molecules when it is cracked in the impregnation tank, resulting in large shrinkage, resulting in pores and cracks in the matrix, resulting in low density of the matrix. The temperature, pressure and vacuum during cracking are ...

However, at present, the biggest disadvantage of the ceramic fiber prepared by the PIP method is that the precursor will release many small molecules when it is cracked in the immersion tank, resulting in large shrinkage, resulting in pores and cracks in the matrix, resulting in low density of the matrix. The temperature, pressure and vacuum during cracking are very important to the effect of impregnation. If they are not properly controlled, the density will not meet the requirements.
