尿素軟管 DEF

應用范圍：用于柴油車輸送DEF尿素溶液。耐DEF尿素溶液腐蝕，幫助柴油車滿足排放規(guī)定，凈化環(huán)境。車用尿素溶液在歐洲稱AdBlue，在北美稱為DEF，是一種液體還原劑，安裝在柴油發(fā)動機排氣系統(tǒng)中，將排氣中的氮氧化物催化還原成氮氣和水的催化裝置，簡稱SCR系統(tǒng)。車用尿素溶液是柴油機專用還原劑，儲存在柴油機上特別的儲存容器內(nèi)，當廢氣從發(fā)動機排出后，它會與廢氣一起到達卡車催化轉化器，然后將氮氧化物轉換為無害的氮和水。使車輛排放達到歐四以上標準。

技術特點：經(jīng)SGS檢測報告，符合SAE-China J2902-2013標準。軟管內(nèi)膠層采用進口高環(huán)保合成橡膠為主的專用配方設計，不含Ca、Cu、Zn、Cr、Ni、Al、Mg、Na、K離子成分，確保軟管加注輸送尿素溶液時高度環(huán)保、清潔，對尿素溶液無作用、無污染、對SCR系統(tǒng)無損害。軟管保護橡膠層耐磨、抗老化、比一般橡膠軟管耐用3~5倍以上。軟管德國產(chǎn)高強度聚酯纖維線增強，加注受壓時軟管無膨脹，確保加注計量精確。防靜電設計: 橡膠層導電，電阻率R＜10^6 ohmm，符合美國ASTM防靜電設計標準。

注   意： 一般橡膠軟管含有大量Ca離子等成分，會污染尿素溶液，對SCR系統(tǒng)的催化劑具有毒害，影響SCR還原的轉換效率！劣質(zhì)的尿素軟管不耐磨、不抗老化，容易磨損與老化！劣質(zhì)的尿素軟管無防靜電設計，加注時容易產(chǎn)生靜電危害！

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
