Control system for producing epoxy resin based on reaction kettle and automatic production method

Abstract

The invention discloses a control system for producing epoxy resin based on a reaction kettle and an automatic production method. The control system comprises a PLC controller, an input component, aninput module, an output module, an execution component, a PC upper computer, a central processing unit, a communication interface, a power supply, and a memory. The input component comprises a temperature sensor, a liquid level meter, a pressure gauge, a mass flow meter, and a flow meter. The output component comprises loading pumps, a hot and cold water regulating valve, an electromagnetic regulating valve, a variable frequency pump, and a three-way regulating valve. The control system for producing epoxy resin based on the reaction kettle and the automatic production method enable the preheating, metering, conveying, mixing reaction and packaging of materials to be monitored and to be automatically adjusted by a PLC system, thereby realizing a complete sealing, automatic and continuous production process. The production process has a high production process efficiency, a stable product quality, a low labor cost, and environmental protection at the production site. The control systemfor producing epoxy resin based on the reaction kettle and the automatic production method have significant economic and social benefits, and ensure that the materials are uniformly mixed and reactedstrictly according to the mass ratio.

Description

technical field [0001] The invention belongs to the technical field of producing epoxy resin with a reactor, in particular relates to a control system for producing epoxy resin based on a reactor, and also relates to an automatic production method based on the control system for producing epoxy resin with a reactor. Background technique [0002] FRP composite materials are widely used due to their light weight and high strength. Epoxy resin is the main material of FRP composite materials. It is generally modified by compounding basic epoxy resin and active diluent to improve its toughness, Heat resistance, weather resistance and construction adaptability, etc. When FRP is formed, it needs to be cured with curing agent, filler and other materials. The traditional process of epoxy resin for FRP is generally produced in a reactor. The advantage is that the amount of raw materials added, the temperature and the reaction time can be flexibly controlled, but the output of a singl...

Problems solved by technology

The entire production process is intermittent, with low mass production efficiency and high labor costs. Differences in process control between batches will cause quality fluctuations and bring quality risks to composite material manufacturing.
