Cold resistance: The pipe will not be frozen and swelled and leaked in the -80℃ environment.
Impact resistance: The pipe wall adopts an "I-shaped" structure, which is resistant to impact and pressure, and will not break even when the foundation sinks. It has strong recovery after deformation and has good adaptability to any foundation.
Aging Resistance: The tubing is usually black and can withstand direct sunlight during storage and construction.
Cold resistance: The pipe will not be frozen and swelled and leaked in the -80℃ environment.
The sound field equipment of plastic sheet production line adopts different screw design and mechanical configuration, which can be applied to produce a variety of plastic sheets.
(Such as: PP, PE, PS, PC, PET, EVA, PMMA, etc.).
The maximum width of the production board village is 2500mm, and the thickness is 0.40mm-30mm. The special design of the extruder screw and the precise temperature control system ensure good plasticization of the rubber compound and stable extrusion with high output.
The flexibility of the pipe is easy to construct, resistant to low temperature impact, relatively good thermal conductivity, recyclable and environmentally friendly, and can be hot-melted.
Using optimized feedback feeding extrusion system, the wall thickness is uniform longitudinally and laterally
The production speed is fast, more than 20 meters per minute, and the residence time in the barrel is short, so the aging resistance is better
Using a unique water-lubricated sizing sleeve, the appearance of the pipe is smooth
Meter production, can be produced according to customer needs.
Applicable raw materials: PVC, PP, PE, etc. The specially designed screw and barrel ensure high-speed extrusion and excellent plasticizing effect of the equipment.
Equipped with three-dimensional electric vacuum cooling water tank. Mechanical height adjustment and lateral adjustment are easy to operate and ensure precise shaping of the product.
The traction device adopts variable frequency speed regulation, and the wear-resistant traction crawler or belt ensures high speed and high stability during traction.
The cutting device works synchronously with the extruder, and the direct drive device of the saw blade can meet the cutting requirements of various products.
Fully automatic production line, specially designed for recycling and recycling of PET (polyester) plastics such as waste mineral water bottles, cola bottles, PET plastic bottles, etc. High-efficiency water-saving equipment, the machine features: beautiful appearance, low energy consumption, high output, practical and reliable. The brand-new rinsing device can be washed at the same time, which greatly improves the production efficiency, and the washing material is clean, meeting the requirements of first-class clean sheet. This equipment can also clean ABS, PVC and other plastics that can sink in water.
MorePET packing belt, also known as plastic steel belt, is a new type of environmentally friendly packaging material that is currently used to replace steel belts in the world. industry, aluminum ingot industry, paper industry, brick kiln industry, screw industry, tobacco industry, electronics industry, textile industry and wood industry, etc.; it is a new type of high-strength packing belt that replaces steel belts Steel strip products.
