Embodiment 1
[0100] Embodiment 1 makes the ultra-high molecular weight polyethylene winding pipe that is added with reinforcing material, flame retardant material and antistatic material
[0101] Weight ratio:
[0102] Plastic substrate: reinforcement material: flame retardant material: antistatic material = 1: 0.2: 0.2: 0.3;
[0103] Dosage: plastic substrate 100kg;
[0104] Reinforcement glass fiber 20kg;
[0105] Flame retardant material decabromodiphenyl ether 12kg;
[0107] Antistatic material Conductive carbon black 30kg; raw materials are commercially available industrial products.
[0108] (Note: The winding material is an ultra-high molecular weight polyethylene plastic substrate with a molecular weight ≥ 1.5 million; the welding material is high-density polyethylene; the same below.)
[0109] One method is: the reinforced ultra-high molecular weight polyethylene winding pipe is wound by multi-layer solid ultra-high molecular weight polyethylen...
Embodiment 2
[0133] Embodiment 2 makes the ultra-high molecular weight polyethylene pipe that adds reinforcing material
[0134] Weight ratio:
[0135] Plastic substrate: reinforcing material = 1:0.8;
[0136] Dosage: plastic substrate 100kg;
[0137] Reinforcement material glass fiber 80kg; raw materials are commercially available industrial products.
[0138] While winding the winding material (plastic solid profile compounded with reinforcing material) by the winding machine, the molten welding material is applied to the adjacent side of the winding winding material, and pressure is applied to melt and bond it into one; the winding The diameter is 2000mm; finally, the wound pipe wall is rolled by a rotary rolling device to make the pipe wall regular and smooth.
[0139] Using the above ratio to make a spiral pipe with a diameter of 2000mm and a standard size ratio (SDR) of 34.3, the results of its working pressure compared with the pure UHMW-PE solid wall pipe are as follows:
[014...
Embodiment 3
[0144] Embodiment 3 makes the ultra-high molecular weight polyethylene pipe that adds reinforcing material, wear-resisting material and antistatic material
[0145] Weight ratio:
[0146] Plastic substrate: reinforcement material: wear-resistant material: antistatic material = 1: 0.6: 0.2: 0.1;
[0147] Dosage: plastic substrate 100kg;
[0148] Reinforcement material carbon / graphite fiber 60kg;
[0149] Wear-resistant material silica powder (or silica sand or glass microspheres) 20kg;
[0150] Antistatic material Conductive carbon black 10kg; raw materials are commercially available industrial products.
[0151] Using the above ratio to make a spiral pipe with a diameter of 2000mm and a standard size ratio (SDR) of 26.0, the results of its working pressure compared with the pure UHMW-PE solid wall pipe are as follows:
[0152] standard size ratio
[0153] Note: The wear rate of the mortar is implemented according to the regulations of QB / T2668-2004. The wear ra...
