冷拔無縫鋼管進行酸洗除銹方法

冷拔無縫鋼管在生產中也是不斷地進行發揮出來巨大的作用的，但是冷拔無縫鋼管在進行維護和保養的過程中並不是一番風順的，由於這樣或者是那樣的原因導致冷拔無縫鋼管生銹的現象是比較多的，對於冷拔無縫鋼管生銹的後果是不能進行使用瞭，喪失瞭冷拔無縫鋼管原來的特性。這個時候就要進行酸洗瞭，那麼冷拔無縫鋼管是怎樣進行酸洗除銹的呢?
Cold-drawn seamless steel pipe is also constantly playing a huge role in production, but the process of maintenance and maintenance of cold-drawn seamless steel pipe is not smooth, because of this or that reason, the phenomenon of cold-drawn seamless steel pipe rusting is more, for cold-drawn seamless steel pipe rusting. The result is that it can not be used and the original characteristics of cold-drawn seamless steel tube are lost. At this time, acid cleaning is needed. How do cold-drawn seamless steel tubes remove rust by acid cleaning?
冷拔無縫鋼管及氧化物在鹽酸和硫酸中的溶解度不同。20℃時，每100g試件在10%的鹽酸溶液中可溶解7.5g三氧化二鐵，而在10%的硫酸溶液中隻能溶解0.98g三氧化二鐵。在相同溫度、濃度下，鹽酸對鐵件的溶解度大於硫酸7倍以上。所以在鋼鐵表面除銹多用鹽酸。鹽酸除銹速度快、效率高、不產生氫脆、表面狀態好，在配制洗液時又比硫酸安全、經濟。
The solubility of cold-drawn seamless steel tube and oxide in hydrochloric acid and sulfuric acid is different. Ferric trioxide can be dissolved 7.5 g in 10% hydrochloric acid solution and 0.98 g in 10% sulfuric acid solution at 20 C. At the same temperature and concentration, the solubility of hydrochloric acid to iron parts is more than 7 times higher than that of sulfuric acid. Therefore, hydrochloric acid is often used to remove rust on steel surface. Hydrochloric acid has the advantages of fast rust removal, high efficiency, no hydrogen embrittlement and good surface condition. It is safer and more economical than sulfuric acid in the preparation of lotion.
用酸洗的辦法危害工人身體健康，排放廢液會造成工業污染，需要"三廢"治理，酸洗後還很容易產生氧化皮銹層，如果鋼鐵設備長期暴露在空氣中，會很快被腐蝕，人們正在尋求能替代此種方法的新工藝。在冷加工行業如：接管、拉絲、擠壓、深拉延等工序，要求磷化膜提供減摩潤滑性能，一般采用鋅系磷化，一是鋅系磷化膜皂化後形成潤滑性很好的硬脂酸鋅層，二是鋅系磷化操作溫度比較低，可在40、60或90℃條件下進行磷化處理，磷化時間4～10min，有時甚至幾十秒鐘即可，磷化膜重量要求≥3g/m2便可。
The method of pickling endangers the health of workers. Discharging waste liquor will cause industrial pollution. 透水地坪It needs to be treated by "three wastes". It is easy to produce oxide rust layer after pickling. If steel equipment is exposed to air for a long time, it will be corroded quickly. People are looking for a new technology to replace this method. In cold processing industry, such as takeover, wire drawing, extr印花地坪usion and deep drawing, phosphating film is required to provide antifriction and lubricity performance. Zinc phosphating is generally used. First, zinc stearate layer with good lubricity is formed after saponification of zinc phosphating film. Second, zinc phosphating operation temperature is relatively low, and it can be phosphated at 40, 60 or 90 C. After treatment, the phosphating time is 4-10 minutes, sometimes even tens of seconds, and the weight of the phosphating film is more than 3g/m2.
冷拔無縫鋼管的酸洗要依據化學原理進行，但是酸洗比較費時間和經歷，大傢可以根據自己的實際情況進行適當的去選擇，另外當冷拔冷拔無縫鋼管出現生銹的時候不要急於用肥皂水和洗衣液進行沖洗，以免出現各種各樣的不利的影響!
The pickling of cold-drawn seamless steel pipe should be carried out according to chemical principle, but pickling takes time and experience. Everyone can choose it appropriately according to their own actual situation. In addition, when the cold-drawn seamless steel pipe rusts, don't rush to wash it with soap water and laundry liquid in order to avoid all kinds of disadvantage. Influence!
