style="text-indent:25px">板式換熱器清洗水垢的工藝要求:1)酸洗溫度：提升酸洗溫度有利于提高除垢效果．如果溫度過(guò)高就會(huì)加劇酸洗液對(duì)換熱器板片的腐蝕，通過(guò)反復(fù)試驗(yàn)發(fā)現(xiàn)，酸洗溫度控制在60~E為宜。 2)酸洗液濃度：根據(jù)反復(fù)試驗(yàn)得出，酸洗液應(yīng)按甲酸81．O％、水17．O％、緩沖劑1．2％、表面活性劑0．8％的濃度配制，清洗效果很好。3)酸洗方法及時(shí)間：酸洗方法應(yīng)以靜態(tài)浸泡和動(dòng)態(tài)循環(huán)相結(jié)合的方法進(jìn)行。酸洗時(shí)間為先靜態(tài)浸泡2 h，然后動(dòng)態(tài)循環(huán)3～4 h。在酸洗過(guò)程中應(yīng)經(jīng)常取樣化驗(yàn)酸洗濃度，當(dāng)相鄰兩次化驗(yàn)濃度差值低于0．2％時(shí)，即可認(rèn)為酸洗反應(yīng)結(jié)束。4)鈍化處理：酸洗結(jié)束后，板式換熱器表面的水垢和金屬氧化物絕大部分被溶解脫落，暴露出嶄新的金屬，極易腐蝕，因此在酸洗后，對(duì)換熱器板片進(jìn)行鈍化處理。板式換熱器的特點(diǎn)是傳熱系數(shù)高。深圳容積式換熱器費(fèi)用哪家便宜</p><p

style="text-indent:25px">換熱器使用過(guò)程中的防腐方法：板片的電化學(xué)保護(hù)法：板換的2大電化學(xué)防腐方法（1）陰極保護(hù)法：利用外加直流電源，使金屬表面上的陽(yáng)極離子受到保護(hù)。但是，這種方法由于耗電量大，所以采用的比較少。（2）陽(yáng)極保護(hù)法：把被保護(hù)的設(shè)備接以外加電源的陽(yáng)極，使金屬表面生成鈍化膜，從而達(dá)到保護(hù)作用。在介質(zhì)中添加緩蝕劑：在腐蝕性介質(zhì)中，加入少量的某些物質(zhì)，使介質(zhì)對(duì)金屬的腐蝕性會(huì)降低，這類物質(zhì)被稱為緩蝕劑。緩蝕劑的加入應(yīng)以不影響生產(chǎn)工藝和產(chǎn)品質(zhì)量為原則。防腐蝕涂層法：在板片表面通過(guò)涂覆方法，覆蓋一層耐腐蝕的涂料保護(hù)層，用于避免金屬表面與腐蝕介質(zhì)的直接接觸。這種技術(shù)方法即經(jīng)濟(jì)又有效，所用涂料大部分為有機(jī)高分子混合物溶液。樂(lè)昌換熱器牌子有哪些</p><p
