鋁排“壽命”的原來與制作工藝有關?

來源:http://www.cettools.cn/ 發布時間:2018-04-11

純鋁很軟強度不大,有良好的延展性,可拉成細絲和軋成箔片,因此成為制作冷庫鋁排的較佳選擇。鋁的表面處理工藝有很多種,其中在鋁排產品上應用得較多的主要是:酸洗、噴砂、堿蝕、酸砂等工藝。其中噴砂屬于物理方法工藝,其他則屬于化學方法工藝。
Pure aluminum is very soft, and has good ductility. It can be drawn into thin wires and rolled into foil. Therefore, pure aluminum is the best choice for making cold storage aluminum platoon. There are many kinds of surface treatment technology for aluminum. Among them, the most commonly used products are acid washing, sandblasting, caustic corrosion, acid sand and so on. Sandblasting is a physical process, while others belong to chemical process.
酸洗工藝是利用酸溶液去除金屬表面上的氧化皮和銹蝕物的方法。采用酸洗耗費時間長,導致加工成本居高不下。對厚氧化皮效果不理想,特別是焊接處黑渣基本上除不掉。而且其耐蝕性很難達到ISO國家標準,因為其有氟化鋁附著在鋁排表面,且氧化后的氧化孔比較大,容易出現表面處理不均勻情況。
Acid pickling is the way to remove oxide scale and rust from metal surface by acid solution. Acid washing takes a long time, resulting in high processing cost. The effect of thick oxide scale is not ideal, especially the black slag at the welding site can not be eliminated. And its corrosion resistance is difficult to reach the national standard of ISO, because its aluminum fluoride is attached to the surface of aluminum, and the oxidation hole after oxidation is relatively large, and it is easy to appear uneven surface treatment.
因此采用這種工藝生產的鋁排表面不整潔,氣密性差,容易產生自然泄漏隱患,如果產生泄漏問題就會大大縮短鋁排的使用壽命,從而給冷庫帶來更多的成本負擔。
Therefore, the surface of the aluminum row produced by this process is not neat, the air tightness is poor, and it is easy to produce the hidden danger of natural leakage. If the leakage problem is produced, the service life of the aluminum platoon will be shortened greatly, thus more cost burden will be brought to the cold storage.
噴砂工藝是采用壓縮空氣為動力,以形成高速噴射束將噴料(銅礦砂、石英砂、金剛砂、鐵砂、海南砂)高速噴射到需要處理的工件表面,使工件表面的外表面的外表或形狀發生變。噴砂處理由于不能對角落及轉折處均勻處理,因此這種工藝使用在鋁排上也有缺陷。
The sand blasting technology uses compressed air as the motive force to form high speed jet beam (copper ore, quartz sand, Jin Gang sand, iron sand, Hainan sand) to the surface of the workpiece to be treated, so that the exterior surface or shape of the surface of the workpiece is changed. Because sandblasting is not able to deal with corners and turning points evenly, the technology is also defective in aluminum fabrication.

堿蝕工藝是對鋁材品質要求高,只能適用于純鋁錠。由于堿蝕工藝要求高如果堿蝕不好則會造成鋁材表面出現長條坑紋、斑點等。如果生產者采用的是再生鋁再加上這種工藝,生產出來的鋁排則會產生很多有害物質,直接產生健康隱患。
Alkali etching process is high quality requirement for aluminum material, and it can only be applied to pure aluminum ingot. Due to the high requirement of alkali etching process, if the alkali corrosion is not good, it will cause long surface pit and spot on the surface of aluminum. If the producer uses recycled aluminum plus this technology, the aluminum row produced will produce a lot of harmful substances, which will directly cause health risks.
在酸砂工藝的介紹上,鋁是電負性很強的金屬,對氧原子有著很強的親和力,鋁在空氣中會生成一層薄而致密的氧化膜,這層氧化膜具有一定的保護作用。但是這層保護膜在自然環境中生成需要的時間長達48天以上,而且不均勻,因此自然環境下出來的鋁排防腐性和氣密性不佳,容易導致制冷劑泄漏。而酸砂工藝則是讓鋁的每在很短的時間內均勻的生成8—12絲的氧化膜,對鋁排起到保護作用。
In the introduction of acid sand technology, aluminum is a very electronegative metal, which has a strong affinity for oxygen atoms. Aluminum will produce a thin and dense layer of oxide film in the air. This layer of oxide film has a certain protective effect. However, this protective film will take more than 48 days in the natural environment, and it is not uniform. Therefore, the anticorrosion and air tightness of the aluminum platoon under natural environment is not good, which can easily lead to the leakage of refrigerant. The technology of acid sand is to make the aluminum oxide produce 8 to 12 wire oxide film evenly in a very short time, and play a protective role for aluminum row.
由于這種氧化膜的電導率非常低,因此能夠阻止陰極反應,使鋁不發生腐蝕。采用這種工藝生產的鋁排產品防腐層厚度均勻,化學性質穩定,能夠有效的減少制冷劑泄漏問題,因此,在一定程度上,采用這種工藝生產的鋁排產品使用壽命會遠遠長于其他工藝產品。
Because the conductivity of the oxide film is very low, it can prevent the cathode reaction and make the aluminum do not corrode. The anticorrosion layer produced by this process is uniform in thickness and stable in chemical properties, and can effectively reduce the problem of refrigerant leakage. Therefore, to a certain extent, the service life of the aluminum production product produced by this process will be far longer than that of other process products.
