熱交換器的材質一般都是不銹鋼的材質，因為，不銹鋼材質的能夠耐腐蝕、華北熱交換器使用壽命長、抗氧化也不錯，更重要的就是安全衛生，所以廣泛的使用在醫藥、食品、用水等方面。螺旋纏繞管式換熱器公司告訴您眼來說板式換熱器也有著四大種類，分別是焊接式、螺旋板式、可拆卸式、蜂窩式這四種，換熱器與水是經常相伴的，所以會出現一個水垢，怎么清洗板式換熱器的水垢？①酸洗溫度晉升酸洗量度有益于進步除垢成效，熱交換器廠家假如溫渡過高就會加深(shen)酸(suan)洗(xi)液對于板式(shi)換熱(re)器板片的(de)侵蝕，經過重復(fu)實驗發覺，酸(suan)洗(xi)量(liang)度掌握正在六(liu)十立(li)方(fang)厘米(mi)為宜(yi)。②酸(suan)洗(xi)方(fang)法(fa)酸(suan)洗(xi)辦法(fa)應以(yi)動態浸泡態重復(fu)相聯合的(de)辦法(fa)停止。正在酸(suan)洗(xi)進程(cheng)中應時(shi)常抽(chou)樣抽(chou)驗酸(suan)洗(xi)深(shen)淺，當(dang)相鄰兩次抽(chou)驗深(shen)淺差值(zhi)低于百分之零點(dian)二(er)時(shi)，即能夠(gou)為酸(suan)洗(xi)反(fan)響終了(le)。
