PE Large volume Grain Storage Tank

Tank introduction:

Wound helically wound tanks with superimposed a molding process to produce polyethylene resin material by heating the extruder extruding molten paste tape, tape under the action of the pressure roller pressing on a preheated mold, since the mold at the same time rotate and move the strip on the mold forming a spiral wound around the strip under the edge of the material resting on the lap belt, and twice in the nip roller material fused together to form an integral continuous wound down complete monolayer . Layer thickness according to the processing parameters can be controlled within 6 to 12 mm. When wrapped around the next layer, the same method described above, in the upper layer of the tank winding, two controlled by adjusting the processing temperature, pressure roller pressure and other parameters to make two completely melted together to form one. The thickness and number of layers wrapped around the body size of the force may be calculated according to the design, a large part of the force may be thicker, force small parts can be thin, the same body in different parts of different thickness (under thick thin) . Can produce diameter 3500mm, length 6000MM single cylindrical section.
advantage:
1) strength and sheet extrusion, consistent strength pipe, larger than the coil welded body strength.
2) enables large-diameter, thick wall pipe, tube processing.
3) appearance, material saving, light weight and low cost.
4) corrosion resistance (chemical resistance) PPH / HDPE is a non-polar plastics, chemical stability, in addition to strong oxidizing acids (fuming sulfuric acid, concentrated nitric acid) and its softening or swelling action of an organic compound, the most chemical media can be stored.
5) Heat resistance PPH softening temperature of 150 ℃, can secure long-term use at 100 ℃. HDPE softening temperature of 100 ℃, long-term safe use at 60 ℃.
Good 6) welding performance, the same material products using a variety of methods of welding, weld factor of up to 0.9 above; good quality of welding, weld strength and the strength of the parent is basically the same.
7) long product life, the correct use, life can be more than 30 years; under harsh conditions can be guaranteed for more than 10 years.
8) non-toxic, health, environmental protection, food store substances, recyclable materials.
