The feature of fiberglasstube for Epoxy Fiberglass Reinforced Pipe For Live Line Tools
Fiberglass tubes is a commonly used material for protecting cables and pipelines, which has good electrical insulation performance and corrosion resistance. This article will introduce the process of fiberglass esophagus, including raw material preparation, preparation process, heat curing, and packaging.
Preparation of raw materials
1. Glass fiber: Glass fiber is the main raw material for preparing glass fiber sleeves, which has high strength and corrosion resistance. During the preparation process, it is necessary to select suitable glass fibers and perform cutting and pre-treatment as needed.
2. Resin: Resin is the adhesive for fiberglass casing, commonly used include epoxy resin, polyester resin, etc. The resin needs to be mixed in a certain ratio to ensure that the cured fiberglass casing has good physical properties.
3. Additives: Additives are materials that play an auxiliary role in the preparation process, commonly including leveling agents, diluents, etc. The selection of additives needs to be determined based on specific process requirements and target performance
