Problems solved by technology

Although its mechanical strength, physical properties and chemical properties such as corrosion resistance have obvious advantages, but at the same time, there are also defects such as flammability and high-voltage static electricity caused by the friction of the material passing through, so that it cannot be used underground. Especially for flammable and explosive occasions
When there is a large solid content in the conveying air flow, the defects are more prominent, which seriously affects the popularization and application of FRP composite pipes.
The industry has studied a variety of processing solutions to improve this characteristic of this product, but so far there is no ideal process and structural solution to fundamentally solve this problem

Abstract

The present invention relates to an improvement on existent fibreglass reinforced plastics composite type pipeline structure and its preparation process. Said invented technological process includes four procedures of base pipe forming, end portion flange connection treatment, forced layer forming and surface decoration, and every procedure uses its correspondent thermosetting resin adhesive formula so as to make said pipeline possess the antistatic and fire-resisting effect.

Description

technical field [0001] The invention belongs to the manufacturing process technology of non-metal logistics conveying pipelines, and is especially suitable for the processing of explosion-proof and fireproof pipelines in petroleum, coal mine, metallurgy, electric power and textile industries. technical background [0002] The composite pipe in FRP products has been widely valued by the industry since its birth, especially this type of pipe has a wide range of raw materials and low cost, easy processing and strong texture, high strength and corrosion resistance, especially can be processed and formed at will. In the production of such products, glass fiber bundles, fabrics made of fibers, mats and thermosetting resins are used as the main body to bond and cure. Although its mechanical strength, physical properties and chemical properties such as corrosion resistance have obvious advantages, but at the same time, there are also defects such as flammability and...
