id="aasm2oo" class="article_content"> 車(chē)用尿素被稱(chēng)為“車(chē)用尿素標準”的GB29518-2013《柴油發(fā)動(dòng)機氮氧化物還原劑尿素水溶液(AUS32)》由質(zhì)檢總局和國標委于2013年5月7日發(fā)布，2013年7月1日實(shí)施！尿素水溶液(AUS32)是指工業(yè)上生產(chǎn)的只含有痕量（少量）縮二脲、氨和水的尿素，不含醛和其他物質(zhì)(如抗結塊劑)，不含硫和硫化物、氯化物、硝酸鹽和其他化合物。<br /> <br /> <span style="white-space:normal;"> </span>符合本標準的AUS32的加注泵和容器上應具有下列標識：AUS32GB29518。據悉，之前部分城市為(或提前)實(shí)施重型柴油汽車(chē)國Ⅳ標準，出臺了有關(guān)車(chē)用尿素的不同版本的地方標準，如北京、上海等地；2013年4月中國汽車(chē)工程學(xué)會(huì )也曾發(fā)布過(guò)由該會(huì )組織編制的《車(chē)用尿素溶液技術(shù)規范》。如今國標版GB 29518-2013發(fā)布實(shí)施，將成為國內統的標準。<br /> <br /> <span style="white-space:normal;"> </span>產(chǎn)品標準是產(chǎn)業(yè)化發(fā)展的基礎，可目前些生產(chǎn)企業(yè)仍在使用不達標車(chē)用尿素或用國三國四尿素來(lái)冒充國五。隨著(zhù)2017年1月1日起，排放標準已經(jīng)提升到國五，國三國四標準早已成為過(guò)去式，政策大力支持使用國五尿素。隨著(zhù)多年來(lái)的發(fā)展，排放標準和尿素液升級為國五標準，不僅技術(shù)上有了很大的提高，在效果是也是達到了很高的標準。<br /> <br /> <span style="white-space:normal;"> </span>那怎么看是不是國標的車(chē)用尿素呢？正規的車(chē)用尿素原材料廠(chǎng)家、車(chē)用尿素溶液廠(chǎng)家都會(huì )在尿素包裝上備注符合GB/29518-2013標準，所以廣大客戶(hù)朋友在選購時(shí)可以根據這個(gè)方面來(lái)挑選符合標準的產(chǎn)品。<br /> <div style="white-space:nowrap;"> <br /> </div></div> <div id="wsyqu22" class="article_editor">
