A kind of c-frp anode tube and its manufacturing method

Abstract

The invention relates to a C-FRP anode tube and a manufacturing method thereof. The method is characterized by comprising the following steps: according to an anode channel, by taking composite carbon fiber cloth and glass fiber yarns as fiber reinforced materials, and taking thermosetting resins, graphite powder and flame retardants are main matrixes, manufacturing and molding through an extrusion forming process. According to the well known extrusion forming process, the special processes and parameters are combined for manufacturing and molding, and the production process can be completely automatically controlled. Compared with a hand lay-up method, the method disclosed by the invention has the advantages that the production efficiency is greatly improved, and an operator does not need to directly touch the matrixes, so that the whole process is performed in a closed unmanned environment, and hidden danger of irritative gases to the human body health is avoided. The fiber content of the fiber reinforced materials is high, so that the product is high in strength and light in weight. Moreover, the quality is stable, the repeatability is high, the product can be cut off at any length according to customer demands, and molds of multiple specifications are not needed to be configured.

Description

technical field [0001] The invention relates to a C-FRP anode tube, in particular to a manufacturing method of a C-FRP anode tube. Background technique [0002] In the industrial production process of chemical industry, light industry, printing and dyeing, medicine, steel, machinery, electronics, instrumentation, electroplating, etc., exhaust gases such as sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, sulfur oxides (SOx), and nitrogen oxides will be produced (NOx), carbon oxides (CO, CO2) and other acid gases need to be treated before they can be discharged. [0003] Acid mist purification tower is a commonly used purification equipment in waste gas treatment projects. During its operation, it is easy to generate "fog" with a particle size of 10-60 microns. "Fog" not only contains water, but also dissolves sulfuric acid, sulfate, For sulfur dioxide, etc., it is necessary to demist the gas containing mist through the gas-liquid separation of the demister,...

AI Technical Summary

Problems solved by technology

[0004] Demisters include lead electric demisters, PVC electric demisters, composite material electric It has an impact on human health; the PVC electric demister is light in weight, but has the disadvantages of poor strength, poor toughness and easy deformation, and has a short service life; the composite electric demister mainly uses glass fiber as the reinforcing material, which has high strength. , long service life, so it gradually replaces the original lead electric demister and PVC electric demister, and has a very broad market prospect

[0005] When manufacturing glass fiber anode tubes or carbon fiber-glass fiber (C-FRP for short) anode tubes as the core of the demister, the current method is mainly the hand lay-up method. Impregnating and exhausting fiber reinforced materials, the work has high labor intensity and low efficiency; the matrix has volatile characteristics, has a certain pungent smell, and the working environment is poor, and the working environment needs to be equipped with ventilation and exhaust facilities; at the same time, due to the glass fiber anode tube The composite structure of multi-layer fiber reinforced materials further reduces the manufacturing efficiency of the hand lay-up method, which is not conducive to large-scale production
