Abstract

The invention belongs to manufacture of fiberglass reinforced polyester (FRP) pipes, and particularly relates to an FRP anode tube and a preparation method thereof. The conductive FRP anode tube is composed of an inner conductive antiseptic layer, a conductive layer, a transition layer and a structure layer, wherein the inner conductive antiseptic layer, the conductive layer, the transition layer and the structure layer are sequentially composited into a whole from inside to outside, two ends of the conductive layer extend and are exposed out of two ends of the conductive FRP anode tube, and the conductive layer is made of metal mesh. The preparation method includes processing steps of cleaning a mould, manufacturing the inner conductive antiseptic layer, manufacturing the conductive layer, manufacturing the transition layer, solidifying for the first time, winding to manufacture the structure layer, solidifying for the second time, demoulding and the like. According to the FRP anode tube and the preparation method thereof, the technical problem in the prior art of being high in product electric resistivity is solved. The existing product has the advantages of being low in electrical resistivity (electric resistance of a DN 300 FRP pipe with the length of 5 meters is 20-30 ohms), reasonable in process design and the like.

Description

technical field [0001] The invention belongs to the manufacture of glass fiber reinforced plastic pipes, in particular to a conductive glass fiber reinforced plastic anode tube and a preparation method thereof. Background technique [0002] At present, there are three main types of anode tubes for electrostatic precipitators: plastic, lead and conductive glass steel. Since the plastic electrostatic demister relies on the liquid film to conduct electricity, the effective precipitation area changes greatly, the operating voltage and current are low, and the effect is not as good as the latter two; the lead anode is relatively bulky. Replaced by conductive FRP, FRP conductive pipe has the advantages of light weight, low price, and outstanding comprehensive performance. However, the conductivity of the current production of conductive FRP anode tubes is not up to the requirements, the resistivity is high, reaching 100 ohms, and the demisting efficiency is low.
