Heat shrinkable fill the mouth with a known thermal mending piece, commonly known as heat-shrinkable sleeve to live, shrinking opening set, pipe weld heat shrink wrap film, is a two-component solvent-free liquid epoxy primer + radiation cross-linked polyethylene mending tape (set) + three-layer structure consisting of an adhesive layer, the structure is known as the three-tier PE outer anti-corrosion coating. Substrate selection The Dow Chemical Company (Dow Chemical Co.) quality DFDD 0588 BK low density polyethylene, after radiation engineering performance is better than Japan's Ube UBEC 600V6, is the preferred material thermal products; adhesives used in Japan's Mitsui EVA, dozens of high-temperature chemical materials, additives Russia butyl rubber, natural rubber, rosin resin refining. Heat shrinkable fill the mouth with the late nineties used in the oil and gas industry, long-distance transport of oil and gas steel pipe weld corrosion, the beginning of this century and widely used in long-distance oil and gas pipe weld corrosion, city gas pipeline network joint corrosion , heating pipe joint corrosion, water pipe joints and other areas of corrosion. Heat shrinkable fill the mouth with a steel pipe weld designed corrosion by covering with a separate piece fixed, shrinking mending tape is made of radiation crosslinked polyolefin substrate and special seals made of hot melt adhesive compound at high temperatures This new type of thermal mending materials with high mechanical strength, stable performance, anti-aging, corrosion-resistant chemical seal adhesive power, easy to operate and so on. Heat shrinkable fill the mouth with antiseptic industry called to live in the sleeve, heat shrinkable sleeve relative called dead muzzle in terms of, in addition to heat shrinkable fill the mouth with body comes tape and fixing pieces, and heat shrinkable mending tape to facilitate large-scale production, construction is also a lot easier. Features: (1) bonding a wide range: bonding with the steel, PE, epoxy coatings. (2) corrosion resistance: can effectively shield the more permeation medium, corrosion, with anti-aging, environmental stress cracking resistance, resistance to ultraviolet radiation performance. (3) high mechanical strength: high compressive strength, impact resistance, shear strength. (4) the use of environmental wide range: can be applied within the range of -25 ~ 35 ℃. (5) No volatile, safety, energy conservation, environmental protection. (6) long service life. (7) Excellent adhesion properties (8) shrink fast, simple construction, easy to operate, easy to install. Excellent waterproof seal: Shrink fill the mouth with the excellent performance of adhesives, radiation cross-linked polyethylene substrate, solvent-free epoxy primer and other materials, good corrosion resistance, good sealing, waterproof, acid and alkali , resistance to chemical corrosion. Site Flexible: the company can provide heat shrinkable fill the mouth with a roll of a variety of diameters, recurring engineering, construction site according to the size of the diameter at the scene be cut for length. This flexibility can help reduce input costs of inventory waste and engineering, project management easy.
