Viscoelastic body with anti-corrosion / pipeline corrosion with viscoelastic / Valves viscoelastic body preservation zone Cui: 18264755877 QQ 3139777687 viscoelastic body corrosion tape is designed for buried pipelines and other equipment, such as preservation or heterosexual flanges, valves , pumps, etc. studied the design of a new anti-corrosion products. This product is a never-cured viscoelastic polymer, has a unique cold flow properties in the process of corrosion and repair can achieve self-healing capabilities to achieve full protection effect. This product without brushing primer, no shedding, no crack, no hardening, with strong adhesion, good chemical resistance and no peeling cathodic protection, the complete elimination of moisture intrusion and microbial corrosion, it has a unique long-term nature. NTD series viscoelastic sealant construction is simple and convenient to handle less demanding on the surface, hand-rust to St2 level to meet the requirements, the material is completely environmentally-friendly, in line with modern anti-corrosion design, is ideal for corrosion protection can be Widely used in the repair of oil and gas pipeline coating and corrosion protection and other fields 3PE coating repair and flanges, valves, pumps and other special-shaped device. Features 1. Surface treatment requirements as low as ST2 / 3, no rust 2. Borax directly applied to steel, PE, PP, FBE and other surfaces without primer; 3. sealing, moisture and oxygen can be completely blocked ; 4. minor defects can self-repair; 5. Field maneuverability, and can be directly applied to heterosexual members corrosion; 6. Using large temperature range, high temperature construction in the alpine environment -30 ℃ -130 ℃, the simple operation; 7 . Quality construction site easy to control, by the environment, personnel skill level has little effect; 8. choose to use PVC / PE / PP outer protection zone, shrinking outer protection zone, fiber composite outer protection zone; 9. abroad through large pipes Practical application, stable and reliable quality technical parameters Technical Data Performance Test Method Typical values ??NTD NTDH insulation resistance (100d) Ω? m2 DIN30670-91 108 108 Density g / cm3 GB / T4472-84 1.41 1.44 absorption% SY / T0414- 2007 Appendix B 0.03 0.03 Shear strength MPa (23 ℃ with / steel) ISO21809-3 Appendix L 0.04 0.07 (60 ℃ with / steel) - - Impact strength (with a packed) GB / T23257-2009 seamless Appendix K 15J impact Point leak point 15J impact peel strength on PE 23 ℃ ISO21809-3 Appendix D 4 10 对 PE 60 ℃ - - 23 ℃ 5 15 steel-on-steel 60 ℃ - - on FBE 23 ℃ 6 17 对 FBE 60 ℃ - - cathodic stripping mm 23 ℃, 24h, -3.5V GB / T23257-2009 Appendix D 1.00 1.00 65 ℃, 30d, -1.5V 3.00 4.00 soaked in hot water (70 ℃, 120d) after peeling strength N / cm for PE 23 ℃ ISO21809-3 Appendix I 3 6 steel 23 ℃ 3 7 对 PE60 ℃ - - Steel 60 ℃ - - Product Specifications Width mm 50,100,200,300 Tape thickness mm> 1.80 Tape Length m 10-30 Cui: 18264755877 QQ 3139777687
