自動(dong)冰(bing)點(dian)(dian)傾點(dian)(dian)凝點(dian)(dian)測(ce)定(ding)儀是基于自動(dong)相轉換法和壓力脈(mo)沖法研制(zhi)而(er)成的(de)(de)物(wu)質低(di)溫流(liu)(liu)動(dong)性專(zhuan)業測(ce)試儀器(qi)。該儀器(qi)適(shi)用(yong)于石油(you)(you)、生物(wu)、化(hua)工等領域，用(yong)于精確測(ce)定(ding)噴(pen)(pen)氣燃(ran)(ran)料(liao)(liao)、生物(wu)燃(ran)(ran)料(liao)(liao)、潤滑油(you)(you)、冷(leng)卻液等物(wu)質的(de)(de)冰(bing)點(dian)(dian)/傾點(dian)(dian)/凝點(dian)(dian)/濁(zhuo)點(dian)(dian)。噴(pen)(pen)氣燃(ran)(ran)料(liao)(liao)、生物(wu)燃(ran)(ran)料(liao)(liao)、潤滑油(you)(you)、冷(leng)卻液等石化(hua)產(chan)品(pin)(pin)在制(zhi)冷(leng)降溫過(guo)(guo)程(cheng)中物(wu)態(tai)會發生過(guo)(guo)渡或(huo)(huo)突變現象，這種物(wu)態(tai)變化(hua)會影響(xiang)油(you)(you)品(pin)(pin)在使用(yong)過(guo)(guo)程(cheng)中的(de)(de)正常流(liu)(liu)動(dong)和輸送能(neng)力。例如噴(pen)(pen)氣燃(ran)(ran)料(liao)(liao)若在低(di)溫下出現結晶，會堵塞燃(ran)(ran)料(liao)(liao)系(xi)統的(de)(de)濾(lv)清器(qi)或(huo)(huo)導管(guan)，導致供油(you)(you)不足、甚(shen)至中斷。油(you)(you)品(pin)(pin)低(di)溫性能(neng)的(de)(de)評(ping)價指標主要包括(kuo)冰(bing)點(dian)(dian)、濁(zhuo)點(dian)(dian)、傾點(dian)(dian)和...

閃(shan)(shan)點(dian)(dian)(dian)是在(zai)規(gui)定的試(shi)(shi)驗條件下，點(dian)(dian)(dian)火源能夠引發可(ke)燃(ran)液體(ti)表面(mian)蒸氣發生閃(shan)(shan)火時的低(di)溫度。閃(shan)(shan)點(dian)(dian)(dian)是化(hua)學品(pin)行(xing)業(ye)，特別是油品(pin)行(xing)業(ye)的一項重要安(an)全標(biao)準與質量指(zhi)標(biao)，關系到可(ke)燃(ran)液體(ti)的使用(yong)(yong)、存儲和(he)運輸安(an)全。閃(shan)(shan)點(dian)(dian)(dian)測(ce)試(shi)(shi)方法(fa)可(ke)以分為(wei)閉(bi)(bi)口(kou)(kou)(kou)閃(shan)(shan)點(dian)(dian)(dian)和(he)開(kai)口(kou)(kou)(kou)閃(shan)(shan)點(dian)(dian)(dian)兩(liang)種。開(kai)口(kou)(kou)(kou)閃(shan)(shan)點(dian)(dian)(dian)實驗由于(yu)可(ke)燃(ran)液體(ti)蒸氣不易積累(lei)，所以其閃(shan)(shan)點(dian)(dian)(dian)測(ce)試(shi)(shi)結果會高于(yu)閉(bi)(bi)口(kou)(kou)(kou)閃(shan)(shan)點(dian)(dian)(dian)。為(wei)了在(zai)評(ping)估過程(cheng)中獲得更大的安(an)全裕量，通常(chang)采用(yong)(yong)閉(bi)(bi)口(kou)(kou)(kou)閃(shan)(shan)點(dian)(dian)(dian)測(ce)試(shi)(shi)的數據。閉(bi)(bi)口(kou)(kou)(kou)閃(shan)(shan)點(dian)(dian)(dian)測(ce)試(shi)(shi)方法(fa)主要分為(wei)賓斯基(ji)-馬(ma)丁閉(bi)(bi)口(kou)(kou)(kou)杯(bei)法(fa)(GB/T261、ASTMD93)、常(chang)閉(bi)(bi)式閉(bi)(bi)口(kou)(kou)(kou)杯(bei)法(fa)(ASTMD6450、SH/T...
