Embodiment 1

[0026] Taking the DN200 FRP pipe as an example, the implementation steps are as follows:

[0027] a) FRP inner lining preparation process:

[0028] A polished steel straight pipe mold with an outer diameter of 200mm is covered with a layer of release film (polyester), and a vinyl ester resin (Changzhou Tianma) with excellent anti-corrosion performance and a glass fiber surface felt (36g / m2) are used in the mold. Make an inner lining layer with a thickness of 2mm on the pipe mold;

[0029] b) bamboo chip pretreatment process:

[0030] Cut fresh moso bamboo into 5-meter-long, 10mm-wide, and 0.6mm-thick bamboo slices, soak them in 15% NaOH solution at 60°C for 40 minutes, dry until the moisture content is 15%, and glue the bamboo slices with 502 glue. Glue the front and back to form continuous bamboo strips, and roll them on the reel for use;

[0031] c) winding process:

[0032] After the lining layer is cured, put the pre-rolled bamboo slices on the winding machine, unwind ...

Embodiment 2

[0037] Taking the DN100 glass steel pipe as an example, the implementation steps are as follows:

[0038] a) FRP inner lining preparation process:

[0039] A polished steel straight pipe mold with an outer diameter of 200mm is covered with a layer of release film (polyester), and a vinyl ester resin (Changzhou Tianma) with excellent anti-corrosion performance and a glass fiber surface mat (36g / m 2 ) making an inner liner with a thickness of up to 2mm on the pipe mould;

[0040] b) the bamboo chip pretreatment process is:

[0041] Cut fresh moso bamboo into bamboo slices 2 meters long, 8mm wide, and 0.5mm thick, soak them in 12% NaOH solution at 50°C for 30 minutes, dry until the moisture content is 10%, and glue the bamboo slices with 502 glue. Glue the front and back to form continuous bamboo strips, and roll them on the reel for use;

[0042] c) winding process:

[0043] After the lining layer is cured, put the pre-rolled bamboo slices on the winding machine, unwind the ...

Abstract

The invention discloses an environmental protection glass-reinforced plastic pipe and production method thereof, wherein the environmental protection glass-reinforced plastic pipe comprises a liner layer (1), a reinforced layer (2) and an outer protection layer (3) which are arranged from inside to outside along pipe diameter direction; the production method comprising the following steps: preparing step of the glass-reinforced plastics liner layer, preprocessing step of the bamboo strip, winding step, outer protection layer step. The environmental protection glass-reinforced plastic pipe has higher intensity, rigidity compared with the polyvinyl chloride, polypropylene pipe, saves oil resources, and has light weight, lower cost, higher production efficiency, same intensity and rigidity compared with the glass-reinforced plastic pipe and glass-reinforced plastic sand pipe and the reinforcement material is the environmental protection, low energy consumption renewable resource. The adhesive of non petroleum product is used to save the petroleum resource. The environmental protection glass-reinforced plastic pipe and production method thereof have positive effect on the development and utilization of the agricultural resources and farmer income increase.

Description

technical field [0001] The invention belongs to a glass steel pipe and a production method thereof, in particular to an environment-friendly glass steel pipe used for water supply and drainage and petrochemical anticorrosion and a production method thereof. Background technique [0002] At present, in the water supply and drainage and petrochemical anticorrosion industries, pipes such as polyvinyl chloride, polypropylene, and glass steel pipes (glass fiber reinforced plastic pipes, glass fiber reinforced plastic sand pipes) are widely used. PVC and polypropylene pipes are light, smooth and corrosion-resistant, but their rigidity and strength are insufficient, and the raw materials are all petrochemical synthetic products; glass steel pipes and glass steel sand pipes have corrosion resistance, high strength, small fluid resistance, The advantages of high rigidity, but the main raw material and reinforcement material of the product is glass fiber with high energy consumption. ...
