如何區分劣質鋁材

现在工業鋁型材的普遍使用，導致一部分商家投機取巧，在制作過程中偷工減料或者摻入劣質原料，制造出一些劣質型材，對于客戶來說，這些劣質産品在使用的過程中會造成很大的影響。而且自然性質柔軟，硬度強，表面具有一定的光澤度，而劣質鋁型材則易脆，使用壽命會大打折扣。怎麽選購到優質的鋁型材呢，下面就讓美誠鋁業小編教大家怎麽去辨別劣質鋁型材，希望我們的這些知識會幫助到您。有以下幾個特征需要注意：
　1、擠壓缺陷：鋁型材擠壓過程中因擠壓設備是否完備，擠壓工藝是否成熟以及操作是否失當，會産生諸如氣泡、夾雜、成層、色差、扭曲等缺陷，影響鋁型材的質量。

2、氧化膜厚度薄：国家标准规定建筑铝型材氧化膜厚度应不小于10um（微米）。厚度不够，铝型材表面易锈蚀、腐蚀。抽验中一些无产名、厂址、生产许可证、合格证的铝型材，其氧化膜厚度仅2至4um，有的甚至没有氧化膜。据专家估算每减少1um氧化膜厚度，每吨型材可减少电耗成本150多元。

3、化學成分不合格：摻入大量雜鋁、廢鋁的鋁型材能大大降低成本，但會導致建築鋁型材化學成分不合格，嚴重危及建築工程安全。

不合格的鋁型材，會大量減少封閉時間，減少了化學試劑損耗，成本降了，使型材耐腐蝕性能也大大降低了，受空氣、雨水、陽光等影響，導致鋁型材變形，甚至造成玻璃破裂、脫落等現象。

‘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.
