      一(yi)、 适用(yong)範圍

        1.常減(jian)壓裝(zhuang)置

      二(er)、産品簡介(jie)

      本緩蝕劑是針(zhen)對國内(nei)煉廠加(jia)工含硫(liu)及高酸(suan)原油的而(er)研制生産(chan)的專(zhuan)用緩(huan)蝕劑(ji)。此緩蝕劑經精(jing)确複配後(hou),在金屬(shu)表(biao)面吸(xi)附性好(hao),空(kong)間排(pai)列整齊,能在金屬表面形(xing)成比一般緩蝕(shi)劑更加緻(zhi)密的(de)保護膜,抑(yi)制腐(fu)蝕的(de)進行。當(dang) hcl-h2s-h­­­­2o型物質(zhi)存在時,緩蝕(shi)劑(ji)改變金屬表面(mian)的電荷狀态,增(zeng)大了腐蝕(shi)反應(ying)的活化能(neng),使腐蝕難(nan)以進行;另(ling)一方面非極性(xing)基團(tuan)多數(shu)排列在金屬表(biao)面,形成疏水膜(mo),阻止(zhi)了與(yu)腐蝕(shi)反應有關(guan)的大部分電荷(he)或(huo)腐蝕(shi)介(jie)質移(yi)動,達到抑(yi)制腐(fu)蝕(shi)的目的(de),達到緩蝕的目(mu)的,緩蝕率大于98%。對初(chu)餾塔(ta),常減壓塔(ta)頂部塔(ta)闆(pan)、餾出線、冷凝(ning)冷卻器(qi)等設備管(guan)線有優良(liang)的緩蝕性(xing)能。

      本(ben)劑(ji)有水溶性和(he)油溶(rong)性兩種,可根據(ju)裝置(zhi)的實(shi)際情(qing)況(kuang)選用。
