color=#2086ee><strong>電熱管</strong></font></a>也不可能在任何環(huán)境都適用，因此也就有可能產(chǎn)生銹蝕。銹斑長(zhǎng)期存在不僅影響外觀，而且會(huì)因不銹鋼管的表面腐蝕減少使用壽命，不銹鋼管表面出現(xiàn)銹斑應(yīng)及時(shí)處理。今天我們就談?wù)勅绾翁幚砑訜峁苌厦娴匿P斑？</span></p><p

16px;">用噴霧或酸洗膏輔助其銹蝕部位重新鈍化形成氧化鉻薄膜，使其重新恢復(fù)耐腐蝕能力。將酸洗膏涂抹于需要處理的表面，涂膜厚度為0.5-2mm，一般反應(yīng)時(shí)間為3-10分鐘以上，0℃以下或氧化皮厚處使時(shí)，需適當(dāng)延長(zhǎng)時(shí)間。處理過(guò)程中最好用刷子刷洗幾次，表面氧化皮完全清除后，用清水（石灰水或堿水更好）沖凈，避免返銹。酸洗之后，為了去除所有的污染物和酸殘留物，用清水進(jìn)行適當(dāng)?shù)臎_洗非常重要。一切處理后用拋光設(shè)備重新拋光，用拋光臘封閉即可。對(duì)局部有輕微銹斑的也可用1：1的汽油、機(jī)油混合液用干凈抹布擦去銹斑即可。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">機(jī)械方法：</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">噴砂清理，用玻璃或陶瓷微粒噴丸清理，湮沒(méi)，刷洗和拋光。用機(jī)械方法有可能擦去以前被清除的料、拋光材料或湮沒(méi)材料造成的污染。所有各種污染尤其是外來(lái)鐵顆粒都可能成為腐蝕的來(lái)源，特別是在潮濕環(huán)境中。因此，機(jī)械清理表面最好應(yīng)當(dāng)在干燥條件下進(jìn)行正規(guī)清理。使用機(jī)械法只能清理其表面，不能改變材料本身的抗腐蝕能力。因此建議在機(jī)械清理后用拋光設(shè)備重新拋光，用拋光臘封閉。</span></p></div>
