如何辨別工業鋁型材表面有沒有氧化處理？

購買工業鋁型材时有表面氧化处理过的铝材要比基材价格高，但若不是业内人事光从外表看是看不出来有没有氧化过的，其实鉴别工業鋁型材是否表面氧化过非常简单，下面美誠鋁業小编为大家介绍介绍两个方法。

方法一：用金屬或指甲輕刮鋁材表面，如無劃痕，且留下的指紋印用軟布很容易擦除，擦除後光澤度不變，即爲氧化鋁；相反如有劃痕或指紋不易擦除，擦後表面有細小劃痕或越擦越模糊即爲非氧化鋁。

方法二：用萬用表的兩只表尖輕輕搭放在鋁材表面（切勿用力按在鋁板上），將電流開至最大，如表上指針滑動即爲非氧化鋁，如電阻很大，萬用表指針不滑動即爲氧化鋁。

上一條美誠鋁業为您阐述工业鋁型材框架有哪些特性？

‘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.
