尿素軟管DEF應(yīng)用范圍：用于柴油車輸送DEF尿素溶液

尿素軟管 DEF

應(yīng)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(dòng)機(jī)排氣系統(tǒng)中，將排氣中的氮氧化物催化還原成氮?dú)夂退拇呋b置，簡(jiǎn)稱SCR系統(tǒng)。車用尿素溶液是柴油機(jī)專用還原劑，儲(chǔ)存在柴油機(jī)上特別的儲(chǔ)存容器內(nèi)，當(dāng)廢氣從發(fā)動(dòng)機(jī)排出后，它會(huì)與廢氣一起到達(dá)卡車催化轉(zhuǎn)化器，然后將氮氧化物轉(zhuǎn)換為無(wú)害的氮和水。使車輛排放達(dá)到歐四以上標(biāo)準(zhǔn)。

技術(shù)特點(diǎn)：經(jīng)SGS檢測(cè)報(bào)告，符合SAE-China J2902-2013標(biāo)準(zhǔn)。軟管內(nèi)膠層采用進(jìn)口高環(huán)保合成橡膠為主的專用配方設(shè)計(jì)，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(shí)高度環(huán)保、清潔，對(duì)尿素溶液無(wú)作用、無(wú)污染、對(duì)SCR系統(tǒng)無(wú)損害。軟管保護(hù)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(guó)產(chǎn)高強(qiáng)度聚酯纖維線增強(qiáng)，加注受壓時(shí)軟管無(wú)膨脹，確保加注計(jì)量精確。防靜電設(shè)計(jì): 橡膠層導(dǎo)電，電阻率R＜10^6 ohmm，符合美國(guó)ASTM防靜電設(shè)計(jì)標(biāo)準(zhǔn)。

注   意： 一般橡膠軟管含有大量Ca離子等成分，會(huì)污染尿素溶液，對(duì)SCR系統(tǒng)的催化劑具有毒害，影響SCR還原的轉(zhuǎn)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(wú)防靜電設(shè)計(jì)，加注時(shí)容易產(chǎn)生靜電危害！

環(huán)保標(biāo)準(zhǔn)：經(jīng)SGS結(jié)構(gòu)嚴(yán)格檢測(cè)，符合歐盟環(huán)保標(biāo)準(zhǔn) ROHS、PAHS、SAE-China J2902-2013標(biāo)準(zhǔn)。

技術(shù)標(biāo)準(zhǔn)：SAE-China J2902-2013

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
