現(xiàn)在，由于冷卻水中含有鈣、鎂離子、酸性碳酸鹽，特別是冷卻水通過金屬表面時會形成碳酸鹽。此外，冷卻水中的溶解氧也會引起金屬腐蝕和鐵銹腐蝕。由于鐵垢的形成，冷卻塔將降低冷卻塔的傳熱效果。嚴(yán)重時，外殼外會噴冷卻水，結(jié)垢嚴(yán)重會堵塞管道，使換熱效果失效。調(diào)查數(shù)據(jù)表明，沉積物對熱傳遞的損耗影響很大，而且隨著沉積物的增加，能量消耗也會增加。即使是一層薄薄的尺寸，也需要將設(shè)備的尺寸部分的運(yùn)行成本提高40%以上。保證冷卻通道中不含礦物沉積物，提高效果，節(jié)約能源，延長設(shè)備壽命，節(jié)約生產(chǎn)時間和費用。 </p> <p style="box-sizing:border-box;margin-top:0px;margin-bottom:10px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> 長期使用機(jī)械清洗、高壓水、化學(xué)清洗（清洗酸洗）等傳統(tǒng)清洗方法等傳統(tǒng)清洗方法，清洗設(shè)備存在諸多問題：清洗設(shè)備中存在規(guī)模等沉積物不能完全清除，酸溶液酸溶液不能完全清除，酸溶液酸腐蝕設(shè)備漏洞，殘余酸會造成材料的二次腐蝕或腐蝕，導(dǎo)致設(shè)備更換.造成設(shè)備更換.。此外，清潔廢液有毒，需要大量資金用于廢水處理。鑒于上述情況，國內(nèi)外努力研制開發(fā)金屬緩蝕清洗劑。它具有高效、環(huán)保、安全、無腐蝕等特點，不僅清洗效果好，而且對設(shè)備無腐蝕，還能保證冷卻塔的長期使用。 </p> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> 冷卻塔材料主要是碳鋼、非碳鋼和銅。當(dāng)碳鋼制成的管板用作冷卻塔時，管板與管子之間的焊縫經(jīng)常會被腐蝕泄漏，泄漏物會進(jìn)入冷卻水系統(tǒng)，造成環(huán)境污染和材料浪費。 </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> 冷卻塔制作時，管板和管線的焊接基本上采用手工弧焊，焊縫形狀上存在不同程度的缺陷，如凹陷、夾渣等，焊縫應(yīng)力分布不均勻。管板部與工業(yè)冷卻水在使用過程中接觸，工業(yè)冷卻水中的雜質(zhì)、鹽類、氣體和微生物都會腐蝕管板和焊縫。相關(guān)研究表明：工業(yè)水不管是淡水和海水，都會對各種離子和溶解的氧氣，在這當(dāng)中氯離子和氧的濃度變化，對于金屬腐蝕現(xiàn)狀起到重要的作用。另外，金屬結(jié)構(gòu)的復(fù)雜程度也會影響到腐蝕形態(tài)。 </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> </div> <p style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;"> 關(guān)于冷卻塔防腐問題，傳統(tǒng)方式還是以補(bǔ)焊為主，但是補(bǔ)焊容易使得管板內(nèi)部形成內(nèi)應(yīng)力，很難清除，可能會形成冷卻塔管板焊縫再次滲漏。如今西方國家選擇高分子復(fù)合材料進(jìn)行保護(hù)。 </p> <p
