Graphite impregnation method
The invention discloses a graphite impregnation method. Graphite is subjected to furan resin impregnation by adopting a curing kettle system; the curing kettle system consists of a curing kettle, a PLC (Programmable Logic Controller), an air inlet control system and an exhaust control system; the curing kettle and the air inlet control system transmit real-time signals to the PLC through the pressure transmitter, the temperature transmitter and the flow transmitter, the real-time signals are compared with program signals preset in the PLC, the PLC sends driving signals to the heater and related valves, the temperature, the pressure and the flow of the system cooperate with one another, and the thermocuring process of the impregnated graphite is completed. Residual gas in the graphite piece and gas generated by reaction dehydration at high temperature are taken away in time, and the backflow problem is solved; according to the invention, the airflow channel is formed in the kettle to take away byproducts generated by furan resin curing in time, so that the reaction is carried out in the forward direction and the curing is sufficient.
本发明公开了一种石墨浸渍方法，采用固化釜系统对石墨进行呋喃树脂浸渍；所述固化釜系统是由固化釜、PLC控制器、进气控制系统、排气控制系统组成；固化釜、进气控制系统将压力、温度和流量变送器向PLC传输时时信号、并将时时信号与PLC中预设的程序信进行比对，PLC向加热器及相关的阀门发出驱动信号，使系统的温度、压力和流量相互协同，完成浸渍石墨的热固化过程。本发明及时带走石墨件中残留气体和反应脱水经高温产生的气体，解决返吐问题；本发明通过在釜内制造气流通道，及时带走呋喃树脂固化产生的副产物，使反应正向进行，充分固化。
