Open-type fill port cover / lap heat shrink sleeve / shrink band / three layers make up the muzzle shrink / shrink two layers make up the muzzle / CEP-4 
 (Lap, pipe welding after use) 
 Port-site meeting with CEP-4 with a shrinking, the inner layer is coated on the surface of the two-component solvent-free steel epoxy primer, the middle layer of hot melt adhesive, the outermost layer (substrate) by a special modification a combination of radiation cross-linked polyethylene. When using the two-tier structure, shrinking with time, you do not primer. 
 CEP-4 zone is shrinking heat shrinkable film with a fixed band (often referred to as corrugated heat shrinkable sleeve-type or open type), the shrinkage rate ≥ 15%. Mainly used for pipe corrosion and mending large area coating damage, defects Mending. Get the latest information on the specific landing http://www.sdxundakj.cn 

 Compatibility of the coating on the tube fine 
 CEP-4 with a product suitable for a variety of heat shrink tube, such as anti-corrosion coating: two polyethylene (2PE), three-layer polyethylene (3PE), three-layer polypropylene (3PP), powder epoxy (FBE), insulation jacket, coal tar enamel, asphalt. Fill site in the pipeline corrosion in the mouth of a large number of applications received, the effect is good. This has been confirmed by many pipeline projects. 
 Creep resistance, long service life. 
 With the performance of hot melt adhesive and primer, the company's shrinking band can adapt to different operating temperatures, creep resistance, long life peer with the pipeline. 
 Preheat temperature is low 
 Materials, application of new technology for on-site meeting to provide a more antiseptic mouth wide space. My company has a good application performance, solvent-free epoxy primer just a warm-up time in mending to 55 ℃ -60 ℃ can be painted, installed immediately shrink, high peel strength obtained for the project provides a great convenience. 
 New materials, new processes, new technology, product performance, quality, continue to maintain excellent. 
 The company attaches great importance to high-tech applications, adhere to continuous improvement, application of new materials, new processes, new technology, product performance, quality, continue to maintain excellent. "No of glue technology" of new fixed-film, the CEP-4 with a shrinking fixed-chip installed in the field, the use of flame along the circumferential direction (flame covers over a fixed film) plus heat shrink, they can take to ensure the end to take the lead shrinking then at almost no slip, so that the whole mending fully melted hot melt adhesive (that is affixed to the lower part of the lap steel baked soft sticky layer play the role of corrosion.) Has been greatly improved quality of the installation. Meanwhile, make the mouth to further improve the adhesive bonding properties, not only in the high and low temperature bonding properties of a wide range of significant enhancements, also has high shear strength. Anti-corrosion pipe mending to ensure more reliable quality. 
 Have excellent waterproof sealing 
 CEP-4 Shrink with the performance of hot melt, radiation cross-linked polyethylene substrate, solvent-free epoxy primer material composition, good corrosion resistance, contraction speed, seal, waterproof performance, acid pH, resistance to chemical corrosion.
