          product introduction
           

          一、 适用範(fan)圍

            1.催化裂(lie)化裝(zhuang)置分(fen)餾系統

          二(er)、産品(pin)簡介(jie)

          臘油、渣油(you)在催化裂化過(guo)程中(zhong),scln的(de)腐蝕是(shi)很強的(de),分餾塔(ta)塔(ta)頂塔盤(pan)和塔(ta)頂管線、冷卻器(qi)、空冷等設備腐蝕相當嚴重。根(gen)據分餾(liu)塔(ta)頂的(de)腐(fu)蝕(shi)特(te)性,本公(gong)司研制(zhi)了針對性的緩蝕(shi)劑。緩(huan)蝕劑的極(ji)性基(ji)團附(fu)着在金屬表面(mian),改變(bian)金屬(shu)表面(mian)的電荷狀(zhuang)态,增(zeng)大了腐蝕反(fan)應的活(huo)化能(neng),使腐蝕難以進行;另一方(fang)面非極性基團多數排列在金屬表(biao)面,形成疏(shu)水(shui)膜,阻止(zhi)了與腐蝕反應(ying)有關的大(da)部分(fen)電荷或腐(fu)蝕介(jie)質移動,達(da)到抑制腐蝕的(de)目的,達到緩蝕的目的,緩蝕率(lü)大(da)于(yu)98%。對分(fen)餾塔頂部塔闆、餾出(chu)線、冷(leng)凝冷卻器(qi)等(deng)設(she)備管(guan)線(xian)有優良(liang)的緩(huan)蝕性能。

          此(ci)緩(huan)蝕(shi)劑分爲水溶(rong)性和油(you)溶性兩(liang)種(zhong)。

          三、質(zhi)量技(ji)術指(zhi)标

          3.本(ben)劑冬天使用時(shi)可适(shi)當用(yong)蒸汽加熱(re)。

          五、包(bao)裝與儲運

          産品(pin)分25kg桶和200kg桶兩種包裝(zhuang)。宜放陰涼(liang)通(tong)風(feng)處,不可靠近明(ming)火。文明裝(zhuang)卸,不可撞擊。
