鋁型材是一種以鋁為主要成份的合金材料，鋁棒通過熱熔，擠壓從而得到不同截面形狀的鋁材料，但添加的合金的比例不同，生產(chǎn)出來的鋁型材的機械性能和應用領(lǐng)域也不同。鋁棒成型后，可以通過熱擠壓工藝，在熱鍛溫度下對鋁棒進行加溫，到適當?shù)臏囟群?，通過訂單不同的模具擠壓出不同斷面型材。擠壓出來的鋁型材，未經(jīng)過時效前硬度偏低，不能作為成品使用，因此，一般來說，都必須經(jīng)過時效來提**度。通常，時效可以分為自然時效和人工時效兩種，目前6xxx鋁型材生產(chǎn)基本上還是以人工時效為主。

style="text-indent:25px">鋁型材擠壓過程中因擠壓設(shè)備是否完備，擠壓工藝是否成熟以及操作是否失當，會產(chǎn)生諸如氣泡、夾雜、成層、色差、扭曲等缺陷，影響鋁型材的質(zhì)量。國家標準規(guī)定建筑鋁型材氧化膜厚度應不小于10um（微米）。厚度不夠，鋁型材表面易銹蝕、腐蝕。抽驗中一些無產(chǎn)名、廠址、生產(chǎn)許可證、合格證的鋁型材，其氧化膜厚度*2至4um，有的甚至沒有氧化膜。據(jù)**估算每減少1um氧化膜厚度，每噸型材可減少電耗成本150多元。摻入大量雜鋁、廢鋁的鋁型材能降低成本，但會導致建筑鋁型材化學成分不合格，嚴重危及建筑工程安全。</p><p style="text-indent:25px">中國的鋁型材行業(yè)起步時，企業(yè)大多都以生產(chǎn)建筑鋁型材為主，加之上世紀90年代到21世紀頭十年的房地產(chǎn)浪潮，很多鋁型材企業(yè)都借此東風賺得盤滿缽滿。但是近幾年來，隨著國家開始嚴控房地產(chǎn)市場，新建住宅數(shù)量開始大幅下降，這就使得每年建筑鋁型材的需求量遠遠不能滿足如雨后春筍般生長的大批鋁企的需求，供過于求開始出現(xiàn)。雖然去年以來房地產(chǎn)政策的“松綁”曾經(jīng)給眾多鋁企帶來了希望，但是該政策已經(jīng)在今年下半年重新收緊，鋁企的日子愈發(fā)艱難。鋁型材，就選江陰嘉科鋁業(yè)有限公司，用戶的信賴之選，有需要可以聯(lián)系我司哦！</p><div

鋁型材作為鋁制行業(yè)的**品牌，對于鋁型材的質(zhì)量控制一向是比較嚴格的。在鋁型材出廠之前，技術(shù)部門會對鋁型材各項指標仔細的進行檢測，對質(zhì)量嚴格把關(guān)。各種成分檢測、物理性能檢測、公差檢測、表面質(zhì)檢等，確保鋁材品質(zhì)。 </p> <p> 就表面氧化檢測來說，除正常的電解著色、色差控制、膜厚檢測、封孔質(zhì)檢、耐候性檢測、耐磨性檢測外，氧化膜的耐腐蝕性檢測也是我們的一個檢測重點。下面我們分析一下鋁型材的耐腐蝕性檢測。 </p> <p> 對鋁型材的氧化膜的耐腐蝕性檢測，我們通常采用鹽霧試驗和滴堿試驗的方式。由于影響鋁型材腐蝕的因素很多，鹽霧試驗主要是檢驗氧化膜的耐酸性能，滴堿試驗主要檢驗其耐堿性能。單一的抗鹽霧性能雖然不能抗其他介質(zhì)的性能，但作為檢測鋁型材有無防腐蝕性能的一種方法，鹽霧試驗在鋁型材耐腐蝕檢驗中被普遍采用。江陰嘉科鋁業(yè)有限公司是一家專業(yè)提供鋁型材的公司。連云港隔熱鋁型材制造價格</p><p

在使用鋁型材時，有時會發(fā)現(xiàn)在材質(zhì)表面上會產(chǎn)生縱向魚粼狀重復性間隔斷紋，很多人不以為然，覺得這只是輕微裂紋，不會影響使用。其實一旦出現(xiàn)這種裂紋，或者出現(xiàn)更嚴重的現(xiàn)象，比如表面呈斷開分離狀，這些情況都會嚴重影響鋁型材的使用性能。鋁型材表面產(chǎn)生裂紋的原因如下：鋁型材擠壓系數(shù)過大，擠壓溫度過高(棒，筒，模三溫)，擠壓速度再過快。擠壓力不穩(wěn)，忽高忽低，或多檔調(diào)速之間速差明顯，換檔時速度轉(zhuǎn)換突快。鋁合金型材擠出時頭端上壓(沖壓)過快，尾端跑速或未減速，死區(qū)鋁大量的滲入。擠壓模具流速比嚴重失調(diào)設(shè)計制造不合理。鋁型材表面產(chǎn)生裂紋的是多方面的因素引起的，這就要求我們在購買使用之前，一定要仔細檢查產(chǎn)品質(zhì)量，盡量通過正規(guī)渠道購買，盡可能的避免這種問題的發(fā)生。
