Embodiment 1

[0029] A preparation process for a braided multi-purpose exhaust and suction pipe, comprising the following steps:

[0030] (1) First, 15 shares of 29.5tex polyester thread are plied together to obtain polyester thread a, then 20 shares of 29.5tex polyester thread are plied together to obtain polyester thread b, and then polyester thread a and polyester thread b are plied together to obtain warp thread 2 , a polyester monofilament 1 with a diameter of 4mm and a polyester monofilament 3 with a diameter of 1.5mm are interwoven with the warp by a double-shuttle circular loom to form a middle reinforced skeleton layer 4, and the gained reinforced skeleton layer weft thread density 31 wefts per 10 cm, and 64 warps per 10 cm;

[0031] (2) Preheat the barrel and mold 7 of the extruder to 180°C for 3 hours, then put the mixture of polyurethane resin, anti-aging agent, carbon black, lubricant, anti-fungal agent and light stabilizer into In the feeding device of the conical twin-screw ...

Embodiment 2

[0035] A preparation process for a braided multi-purpose exhaust and suction pipe, comprising the following steps:

[0036] (1) Polyester thread a obtained by plying 15 shares of 29.5tex polyester thread, then 20 shares of 29.5tex polyester thread to obtain polyester thread b, and then polyester thread a and polyester thread b to obtain warp thread 2, A polyester monofilament 1 with a diameter of 3 mm and a polyester monofilament 3 with a diameter of 1 mm are interwoven with the warp by a double-shuttle circular loom to form a middle reinforced skeleton layer 4, and the weft density of the obtained reinforced skeleton layer is 32 wefts per 10 cm, and 60 warps per 10 cm;

[0037] (2) Preheat the barrel and mold 7 of the extruder to 220°C for 2 hours, and then put the mixture of polyurethane resin, anti-aging agent, carbon black, lubricant, anti-fungal agent and light stabilizer into the In the feeding device of the conical twin-screw extruder;

[0038] (3) Put one end of the ...

Abstract

The invention discloses a woven multi-purpose exhaust-suction dual-use pipe and a preparation technology thereof. The multi-purpose exhaust-suction pipe comprises a smooth inner rubber layer, a high-strength enhancement layer and a corrugated outer rubber layer, wherein the enhancement layer is woven through polyester monofilaments and plied polyester threads. The woven multi-purpose exhaust-suction dual-use pipe not only can transport liquids and gases but also can transport particles like cement powder, has the advantages of being light in weight, quick in water outlet, easy to be bent and coiled, high pressure resistant, negative pressure resistant, corrosion resistant, and the like, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of exhaust and suction pipes, in particular to a braided multipurpose exhaust and suction pipe and a preparation process thereof. Background technique [0002] Hose for conveying fluid media such as water, oil, mud, and powder particles. In the prior art, commonly used pipes are rubber pipes and PVC pipes. Rubber water pipes have excellent stamping resistance and high and low temperature resistance, but their Heavy weight, poor wear resistance, large conveying resistance, complicated preparation process, harsh storage environment, poor resistance to organic solvents, not suitable for conveying organic substances such as fuel oil; the pipe wall of PVC pipe is very smooth, the resistance to fluid is very small, and the energy consumption of conveying Low, but its flexibility is poor, low strength is prone to breakage, cracks, glue opening, etc., and it is not resistant to high temperature, and it is prone to h...
