针对选择螺旋(xuan)板式换热器的清理工具有哪些(xie)呢(ni)?

　　目前(qian)，对于板式(shi)换热(re)器清(qing)洗工(gong)具的(de)(de)选择，酸(suan)(suan)(suan)(suan)(suan)(suan)洗是目前(qian)采用(yong)的(de)(de)主(zhu)要方式(shi)，它包括有(you)(you)机(ji)酸(suan)(suan)(suan)(suan)(suan)(suan)和无机(ji)酸(suan)(suan)(suan)(suan)(suan)(suan)。有(you)(you)机(ji)酸(suan)(suan)(suan)(suan)(suan)(suan)主(zhu)要有(you)(you)：草酸(suan)(suan)(suan)(suan)(suan)(suan)、甲酸(suan)(suan)(suan)(suan)(suan)(suan)等。无机(ji)酸(suan)(suan)(suan)(suan)(suan)(suan)主(zhu)要有(you)(you)：盐酸(suan)(suan)(suan)(suan)(suan)(suan)、硝酸(suan)(suan)(suan)(suan)(suan)(suan)等。

　　根(gen)据板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器结构和(he)工艺(yi)、材质和(he)水垢成分(fen)分(fen)析得出：1.板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器材质为(wei)(wei)镍钛合(he)金，不(bu)(bu)能选择盐酸(suan)(suan)为(wei)(wei)清(qing)洗(xi)(xi)液(ye)(ye)，否则(ze)(ze)容易(yi)对(dui)(dui)板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器板(ban)(ban)(ban)(ban)片产生(sheng)强腐(fu)(fu)(fu)蚀，缩(suo)短板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器的(de)(de)使用寿命。2.螺(luo)旋板(ban)(ban)(ban)(ban)换(huan)(huan)(huan)热(re)器流通面(mian)(mian)积小， 内部结构复(fu)杂，清(qing)洗(xi)(xi)液(ye)(ye)若产生(sheng)沉淀则(ze)(ze)不(bu)(bu)易(yi)排放。通过反(fan)复(fu)试(shi)验(yan)发现，选择甲(jia)酸(suan)(suan)作为(wei)(wei)螺(luo)旋板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器清(qing)洗(xi)(xi)液(ye)(ye)效(xiao)(xiao)果最佳。在甲(jia)酸(suan)(suan)清(qing)洗(xi)(xi)液(ye)(ye)中加入缓冲剂和(he)表(biao)面(mian)(mian)活性剂，清(qing)洗(xi)(xi)效(xiao)(xiao)果更好，并可降低清(qing)洗(xi)(xi)液(ye)(ye)对(dui)(dui)螺(luo)旋板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器板(ban)(ban)(ban)(ban)片的(de)(de)腐(fu)(fu)(fu)蚀。 通过对(dui)(dui)螺(luo)旋板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器水垢样本的(de)(de)化学试(shi)验(yan)研究表(biao)明，甲(jia)酸(suan)(suan)能够有(you)效(xiao)(xiao)地(di)清(qing)除(chu)水垢。通过酸(suan)(suan)液(ye)(ye)浸泡试(shi)验(yan)，发现甲(jia)酸(suan)(suan)能有(you)效(xiao)(xiao)地(di)清(qing)除(chu)附在螺(luo)旋板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器板(ban)(ban)(ban)(ban)片上的(de)(de)水垢，同(tong)时它对(dui)(dui)螺(luo)旋板(ban)(ban)(ban)(ban)式(shi)(shi)换(huan)(huan)(huan)热(re)器板(ban)(ban)(ban)(ban)片的(de)(de)腐(fu)(fu)(fu)蚀作用也(ye)很小。

　　所以，在螺旋板式(shi)换热(re)器清洗工具的选择上(shang)，小编(bian)建议大家可以选用甲酸进行操作，能够(gou)有(you)效的清除螺旋板式(shi)换热(re)器表面水垢并(bing)且对板片的腐蚀作用也很小，不会影响螺旋板式(shi)换热(re)器的日常使(shi)用和(he)性能。
