Overview

When producing and wholesaling polyurethane plastic brackets, according to the standard requirements for peel strength testing, the temperature should be at 20 degrees Celsius and the radiation cross-linked polyethylene heat shrinkable tape should be wrapped for 24 hours before testing. The testing temperature here refers to the temperature of the steel pipe, not the climate temperature. Often, when the temperature is high, the adhesive layer of anti-corrosion tape is relatively soft, and its viscosity is greatly affected by temperature. Steel pipes are prone to heat absorption, and the temperature is more than ten degrees higher than the ambient temperature, often exceeding the detection temperature.

Product Details

Production and wholesale of polyurethane plastic brackets

The product deviates from the traditional process and is made of special nickel chromium alloy mesh belt through a special hot melt integration equipment on PE sheet, which is formed in one go. Due to the use of high-quality raw materials and a certain proportion of EVA hot melt adhesive for PE sheet, it is produced by co extrusion equipment and mixed and melted by a composite machine head, and then subjected to corona treatment. Therefore, a small amount of adhesive material can overflow around during welding melting. In addition, the nickel chromium alloy mesh has a fine texture, uniform arrangement, and high heat generation per unit time, which can be perfectly integrated with PE pipelines, with obvious sealing effect and good welding effect.

This product is made of high-density polyethylene (HDPE) as the substrate and electric heating mesh hot pressed and embedded composite. After being connected by electricity, a molten material flow is formed between the product and the pipe, and molecules can penetrate and diffuse each other. After cooling, a strong bond is formed, and a 45 degree guide angle is designed on both sides to be used as a traction pipe fitting. The connection strength is higher than that of the base material, the sealing effect is good, the sealing performance is high, the corrosion resistance and aging resistance are high, and the construction is convenient and fast. The product is suitable for: direct buried insulation pipe joint repair; Central control winding pipe, steel strip reinforced pipe spiral corrugated pipe; Directly buried oil insulation pipe joint repair. Electric fusion welding machine: This product is designed and developed specifically for the welding of high-density polyethylene polyurethane insulation pipes with electric fusion sleeves (belts). It has a high degree of automation, with automatic conversion when powered on at 220V/380V, easy to carry weight, durable and suitable for various construction environments.

Performance characteristics of polyester heat shrinkable tape: 1. The heat shrinkage can reach 6%~10%, and the bundling is firm, durable, and does not retract. 2. High tensile strength, with mechanical strength tens of times higher than that of cloth tape. 3. Pure chemical substance, with no defects such as hair, loose lines, or stripes on the surface, and does not contain dirt or other substances harmful to electrical insulation. 4. Avoiding numerous corner components, saving costs and space; More convenient, reliable, and aesthetically pleasing. Heat shrink tape (abbreviated as shrink tape) is made of ATY (300dtex) high shrink polyester fiber. Heat shrink tape has good mechanical properties and high insulation binding tightness, and is suitable for insulation materials of transformers, transformers, and motors.

Used for connecting thermal pipeline interfaces, with high adhesive strength, good density performance, corrosion resistance, long service life, and easy use.

Performance characteristics: The connection strength between the electric melting sleeve and the jacket tube is high, the sealing effect is good, the air sealing performance is high, the polyurethane does not leak, it is corrosion-resistant, and the construction is convenient and fast.

Before foaming with polyurethane, a single support bracket for the jacket leather needs to be tied to a steel pipe with wire strings to support it. There are also connected brackets shaped like a sun that can be directly fitted onto pipes, saving you labor costs.
Supporting the jacket leather to ensure concentric support brackets for the insulation layer,
Support the jacket leather to ensure that the insulation layer thickness is the same for the support bracket used in the thermal pipeline,
The support between internal steel pipes such as polyurethane pipes and external pipe shells ensures consistent thickness of the polyurethane insulation layer, making the entire steel pipe concentric.
