尿素软管 DEF

尿素软管 DEF

应用范围：用于柴油车输送DEF尿素溶液。耐DEF尿素溶液腐蚀，帮助柴油车满足排放规定，净化环境。车用尿素溶液在欧洲称AdBlue，在北美称为DEF，是一种液体还原剂，安装在柴油发动机排气系统中，将排气中的氮氧化物催化还原成氮气和水的催化装置，简称SCR系统。车用尿素溶液是柴油机专用还原剂，储存在柴油机上特别的储存容器内，当废气从发动机排出后，它会与废气一起到达卡车催化转化器，然后将氮氧化物转换为无害的氮和水。使车辆排放达到欧四以上标准。

技术特点：经SGS权威检测报告，符合SAE-China J2902-2013标准。软管内胶层采用进口高环保合成橡胶为主的专用配方设计，不含Ca、Cu、Zn、Cr、Ni、Al、Mg、Na、K离子成分，确保软管加注输送尿素溶液时高度环保、清洁，对尿素溶液无作用、无污染、对SCR系统无损害。软管保护橡胶层超强耐磨、抗老化、比一般橡胶软管耐用3~5倍以上。软管德国产高强度聚酯纤维线增强，加注受压时软管无膨胀，确保加注计量精确。防静电设计: 橡胶层导电，电阻率R＜10^6 ohmm，符合美国ASTM防静电设计标准。

注   意： 一般橡胶软管含有大量Ca离子等成分，会污染尿素溶液，对SCR系统的催化剂具有毒害，影响SCR还原的转换效率！劣质的尿素软管不耐磨、不抗老化，容易磨损与老化！劣质的尿素软管无防静电设计，加注时容易产生静电危害！

Applications:
Diesel DEF urea solution dedicated delivery hose, highly clean environment, free of harmful ions vehicle SCR system components, in line with SAE J2902-2013 standards to protect vehicle SCR system to help diesel vehicles meet emissions regulations. Inside and outside the plastic dual anti-static, gas stations and other needs very appropriate song repeatedly Rao, friction car rolled places.
Technical characteristics:
Special vehicles with urea solution green rubber formula to ensure a high degree of environmental clean urea solution, no secondary pollution, no damage to the SCR system. Super anti-aging, anti-song Rao, wear-resistant car rolled rubber protective layer. Double inner layer and an outer layer of anti-static proof design, comply with the requirements of the gas station filling metering. Antistatic safety, inside and outside the whole conductive layer over the intermediate metal hose line plus more reliably prevents the generation of electrostatic charge. Or connected via a conductive rubber layer metal fittings into the earth, to prevent the occurrence of danger.
Antistatic standard: Conductive rubber layer, specific resistance R<10^6 ohmm.
Note: Conventional rubber tubes and hoses do not meet the standards of urea, urea solution will pollute, poison for the SCR system, effect vehicle emissions standards.
Construction:
Tube: Black anti-static, private car green rubber formulations with urea solution.
Reinforcement: High-strength synthetic fiber braid.
Cover: Black super super wear-resistant anti-static, anti-aging synthetic rubber.
Temperature range:-40 °C +90 °C
Standard/Approval:ROHS、PAHS、SAE J2902-2013
