三、車用尿素液配方與制作方法
1、配方：（1）普通型尿素溶液配方比例：高純尿素32.5%、去離子水67.5%。（2）防凍型尿素溶液配方比例：高純尿素32.5%、去離子水52.5%、甲醇15%。2、制作方法：將32.5%的高純尿素和67.5%的高純水進行混配，就可以得到車用尿素液體。自制車用尿素液比較麻煩，而且不一定能保證純度和雜質含量，因此還是建議大家通過正規渠道購買優質車用尿素品牌的產品。
四、車用尿素生產成本及利潤分析
車用尿(niao)素(su)(su)分(fen)為大桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)(zhuang)(zhuang)和(he)小(xiao)桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)(zhuang)(zhuang)，大桶(tong)(tong)(tong)(tong)(tong)一般是(shi)噸桶(tong)(tong)(tong)(tong)(tong)，每(mei)(mei)(mei)(mei)(mei)(mei)桶(tong)(tong)(tong)(tong)(tong)可以裝(zhuang)(zhuang)(zhuang)一噸，主要用在自有車隊(dui)、公(gong)交公(gong)司、汽運公(gong)司、物流公(gong)司、汽修廠等(deng)等(deng)，方便添加(jia)，批量采購，每(mei)(mei)(mei)(mei)(mei)(mei)噸價格1600-1800元(yuan)(yuan)。小(xiao)桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)(zhuang)(zhuang)每(mei)(mei)(mei)(mei)(mei)(mei)桶(tong)(tong)(tong)(tong)(tong)10L，每(mei)(mei)(mei)(mei)(mei)(mei)桶(tong)(tong)(tong)(tong)(tong)價格在20-30元(yuan)(yuan)，主要應用于加(jia)油站、汽配城、維修廠等(deng)等(deng)汽車流動(dong)大的場(chang)所，便于購買。車用尿(niao)素(su)(su)原料2000-2200元(yuan)(yuan)/噸，去離(li)子水自己生產10元(yuan)(yuan)/噸。一噸車用尿(niao)素(su)(su)原料加(jia)水可以出3噸尿(niao)素(su)(su)溶液，綜(zong)合成本(ben)(ben)約700元(yuan)(yuan)每(mei)(mei)(mei)(mei)(mei)(mei)噸。每(mei)(mei)(mei)(mei)(mei)(mei)個桶(tong)(tong)(tong)(tong)(tong)4元(yuan)(yuan)，包(bao)材加(jia)起來10L裝(zhuang)(zhuang)(zhuang)每(mei)(mei)(mei)(mei)(mei)(mei)桶(tong)(tong)(tong)(tong)(tong)成本(ben)(ben)11元(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)左(zuo)右。市場(chang)價10L裝(zhuang)(zhuang)(zhuang)20-30元(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)-11元(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)成本(ben)(ben)=利(li)潤(run)約9-19元(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)，大桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)(zhuang)(zhuang)每(mei)(mei)(mei)(mei)(mei)(mei)噸1700元(yuan)(yuan)/噸-成本(ben)(ben)700元(yuan)(yuan)/噸=利(li)潤(run)1000元(yuan)(yuan)/噸。
五、車用尿素是什么原理
車(che)(che)用(yong)(yong)尿(niao)(niao)(niao)素是指濃(nong)度(du)為32.5%且(qie)溶劑為超(chao)純水(shui)(shui)的(de)(de)尿(niao)(niao)(niao)素水(shui)(shui)溶液，生(sheng)產原料為車(che)(che)用(yong)(yong)尿(niao)(niao)(niao)素專用(yong)(yong)原料和(he)超(chao)純水(shui)(shui)，它進入(ru)汽車(che)(che)內部后，通過(guo)尿(niao)(niao)(niao)素罐噴射系統(tong)，噴射于汽車(che)(che)排(pai)氣(qi)管發生(sheng)反(fan)應；排(pai)氣(qi)管上安裝有(you)尿(niao)(niao)(niao)素計(ji)量(liang)噴射裝置，在溫度(du)達到300℃-500℃時自動噴入(ru)尿(niao)(niao)(niao)素溶液，在催化(hua)劑的(de)(de)作用(yong)(yong)下尿(niao)(niao)(niao)素（NH2CONH2）水(shui)(shui)解產生(sheng)NH3和(he)CO2，NH3與NOx反(fan)應，生(sheng)成氮氣(qi)和(he)水(shui)(shui)排(pai)出，起到凈化(hua)尾氣(qi)的(de)(de)作用(yong)(yong)。
