在鋁板市場上怎樣才能購買到高性價比的鋁板

來源:http://www.kangyanghua.com/ 發布時間:2018-01-10

一,查看鋁板的外包裝。好的包裝不僅顯示出鋁板廠家的實力,舍得花大價錢在產品包裝上付出,而且也顯示出廠家比較重視產品的防護。另外也顯示出廠家對鋁板生產管理十分到位。
One, check the outer packing of the aluminum plate. Good packaging not only shows the strength of the aluminum plate manufacturer, but also pays for the product package, and it also shows that the manufacturers attach much importance to product protection. In addition, it is also shown that the manufacturer is very effective in the management of the aluminum plate production.
二,查看鋁板的表面。好的鋁板,表面無輥印、黑點、劃傷、油斑、腐蝕、裂變等缺陷;板型平整,無明顯彎曲;單張鋁板對角線一致;整件鋁板擺放整齊,每張鋁板長寬一致。如鋁板表面覆有保護膜,將保護膜揭開,至少查看整個寬度的板面,避免有缺陷被掩蓋。
Two, look at the surface of the aluminum plate. Good aluminum, surface roller, black spots, scratches, grease, corrosion, fission and other defects; flat plate, no bending sheet aluminum; diagonal consistent; the whole plate neatly, each plate length and width consistent. If the surface of the aluminum plate is covered with a protective film, the protective film will be opened and at least the width of the plate is looked at at least to avoid the defects being covered.
三,用千分尺、米尺、游標卡尺等測量工具進行測量。根據需求,選擇鋁板廠家提供的產品進行測評。并根據所測尺寸的數量級選擇不同的測量工具,對鋁板的厚度、寬度、長度、不平度、對角線等產品進行測量,具體尺寸偏差可參考GB/T 3880。1-2006。每一次測量至少選擇三個點進行測量,測算鋁板尺寸或者誤差是否均勻、是否都在國標之內。

鋁板生產廠家
Three, measured with micrometer, vernier caliper, meter measuring tools. According to the demand, select the products provided by aluminum plate manufacturers to evaluate. According to the size of the measured size, different measuring tools are selected to measure the thickness, width, length, roughness and diagonal line of the aluminum plate. The specific size deviation can be referred to GB/T 3880. 1-2006. At least three points are selected for each measurement to measure the size or error of the aluminum plate or whether it is within the national standard.
四,要求鋁板廠家提供鋁板材質合格證明單。好的鋁板廠家都會對每批次的鋁板進行成分、性能等方面進行測試。鋁板廠家提供材質合格證明單后,查看材質單對應產品的成分、性能是否控制在國標范圍之內,具體數值可參考GB/T 3880-2006。且要注意材質單必須加蓋廠家的公章。如果在鋁板的使用過程中出現問題,可以材質單作為依據對鋁板進行檢測,并像廠家提出質量異議。
Four, the aluminum plate manufacturer is required to provide the certificate of qualification for the material of the aluminum plate. A good aluminum manufacturer will test the composition and performance of each batch of aluminum plate. After the aluminum plate manufacturer provides the material qualification certificate, check whether the ingredients and properties of the material correspond to the national standard. The specific value can be referred to GB/T 3880-2006. And pay attention to the material sheet must be stamped with the manufacturer's official seal. If there is a problem in the process of using the aluminum plate, the material can be used as the basis for the inspection of the aluminum plate, and the quality objection is put forward by the manufacturer.
五,廠家售后服務。了解廠家的售后服務如何,如果遇到問題鋁板廠家能否及時解決,這樣才能更無后顧之憂。
Five, the after-sales service of the manufacturer. How to understand the after-sales service of the manufacturers, if the problem can be solved in time, this can be more worried.
