常見的工業鋁材上色方式有哪些？

工業鋁材上色是在鋁型材擠壓出來後的一個重要步驟，因爲鋁棒擠壓出來後的鋁型材表面沒有經過任何處理，而鋁合金成分中的鋁元素在空氣中和空氣中的水分和氧元素很容易發生作用形成表面腐蝕。所以需要在表面覆上一層氧化膜阻斷鋁合金和空氣直接接觸，形成一層保護膜。本文主要介紹常見的工業鋁材上色方式有哪些？

文章开端我们就解释了为什么要给工業鋁材上色，上色其实就是给铝合金型材表面增加保护膜。目前的铝合金型材上色方式有：阳极氧化、电泳、喷涂以及木纹转印这四种。其中，应用在工業鋁型材上的大多数是阳极氧化和喷涂，而电泳和木纹转印一般都是应用在建筑铝材上面。阳极氧化就是将工业铝材浸在酸碱溶液中通直流电，使表面形成一层致密的厚度达到12微米的人工氧化膜（注意：通電時間的長短可以控制氧化膜的厚度）。而噴塗就是將擠壓好的鋁型材表面進行粉末噴塗處理。陽極氧化一般黑色和銀白色較多，而噴塗常見的顔色比較多樣化一些，另外，陽極氧化使用壽命長，多年如故，易清潔保養，而噴塗很容易掉漆。

‘Well, if that isn’t a rude speech! But perhaps you’re tired, Thomas, with all this grandeur. For me, I never felt fresher in my life: it comes quite natural to me.’ ARCHERY ATTENDANT. ARCHERY ATTENDANT. The Japanese are excellent sailors, both on their junks and on the foreign ships that have been introduced to their service since the opening of the country to other nations. But the Japanese landsman has a horror of the water, and cannot be induced to venture upon it. In this respect the Japanese are not unlike the Italians, who are naturally a maritime nation, and have covered themselves with marine glory in times that are past. But the Italian landsman is ready to suffer any inconvenience rather than risk himself on the ocean, and not a more woe-begone being can be found in the world than a sea-sick Italian unless it be a sea-sick Japanese. HORSE CARRYING LIQUID MANURE. HORSE CARRYING LIQUID MANURE. No, he would not; only wagons went that way, to cross the creek by a small bridge. I could cut off nearly two miles by taking the bridle-path that turned sharply down into the thick woods of the creek-bottom about a quarter of a mile from the house and crossed the stream at a sandy ford. "Ride round," he said, "and I'll show you from the front of the house." Plato or bridge--is fundamentally and always interested in clothes. I've been writing a book, all last winter in the evenings, and all 24 Now for a race, Larry muttered, almost automatically moving the throttle wider as he prepared to alter their course. She did not. He had merely told her that her father was his friend and had died on the plains. "She thinks her mother died at Stanton. It is so near the Mescalero Agency that I let it go at that." papers reports that he was kild at thfe battle of "Do you men know of a squad of Injianny recruits commanded by Serg't Klegg?" "Where may I learn the others?" But Gornom didn't answer, and Cadnan's breathing-space was over. He had to be back at the board, pushing buttons, watching carefully. Gornom stood behind him, peering over his shoulder with a cloudy eye. Neither said a word until the new spell of work was over. Then Cadnan repeated his question. Being excerpts from memo directives sent between executives of Associated Metallic Products, Ltd., a corporation having its main offices within Dome Two, Luna City, Luna, and associated offices on all three inhabited planets, the memo directives being dated between May fourteenth and May twenty-first, in the Year of the Confederation two hundred and ten. During the next ten years the farm went forward by strides. Reuben bought seven more acres of Boarzell in '59, and fourteen in '60. He also bought a horse-rake, and threshed by machinery. He was now a topic in every public-house from Northiam to Rye. His success and the scant trouble he took to conciliate those about him had made him disliked. Unprosperous farmers[Pg 124] spoke windily of "spoiling his liddle game." Ditch and Ginner even suggested to Vennal that they should club together and buy thirty acres or so of the Moor themselves, just to spite him. However, money was too precious to throw away even on such an object, especially as everyone felt sure that Backfield would sooner or later "bust himself" in his dealings with Boarzell. "This place suits me, and I think I could do well for myself out here. I feel I should get on better if I was my own master.... She was good and sensible-like, and looked as if she could manage things. So I married her.... We're starting up on a little farm near Jo'burg ... I can't see it matters her being Dutch ... fifty acres of pasture ... ten head of cattle ... niggers to work ..." The treasurer turned pale, and hung his head.
