如何選擇裝修必備品五金配件教你選擇五金

據了解,市場上一些商家宣稱的鋁材料其實只是含有鋁成分的合金材料,其中摻和有硅、鎂等其他成分,而表面膜層厚度及表面處理工藝等因素,也往往影響著材料的價格及品質。表面處理工藝主要有氧化、磨砂、電鍍、木紋及烤漆等,產品價格也相差較大。

羅慶友介紹說,市場上常見的鋁合金材料主要有鋁鎂合金與氧化鋁兩種,兩者間的價格相差近三分之一,由于氧化鋁和鋁鎂合金材料表面看上去差不多,消費者辨別起來難度較大,不過還是可以從手感、水漬等方面判斷。鋁鎂合金材料相對較重,表面較為光滑,不容易出現水漬痕跡,韌性好。而氧化鋁材料則表面粗糙,容易發黑或出現水漬痕跡。同時,如果兩者表面出現了輕微劃痕,鋁鎂合金材料容易抹掉,而氧化鋁則很難去掉。此外,門把手還會因為孔距、型號的不同,價格也相差很大。

謹防不銹鋼變“不銹鐵”

有些市民反映,在購買不銹鋼配件產品時發現有的是不銹鐵的,也就是在不銹鋼材料中摻合了不少鐵成分,價格相差將近兩倍。以浴巾架為例,不銹鋼材質的價格平均在每個200元,而不銹鐵的價格只有每個70元,表面上兩者基本相同,但不銹鋼材料表面更光亮些,不銹鐵使用時間一長,表面容易發黑生銹。

此外,還有一些假冒產品使用劣質鋁合金為原料,表面鍍上一層金屬亮光,冒充高檔不銹鋼,判斷這兩種材料,市民購買時可以敲打表面,如果發出清脆的聲音則大多是不銹鋼,如果是沉悶的聲音,則很可能是“披著外衣”的鋁合金。

衛生間最好用銀鏡

據了解,目前家庭裝修普遍使用的鏡子主要分為普鏡和銀鏡兩種,兩者的價格相差30%左右,銀鏡的市場價格平均在每平方米80-90元,而普鏡只有每平方米50元,而且質量也相差很大。

用材的不同是造成兩者價格不同的主要因素,銀鏡背面先涂了一層水銀再刷漆,而普鏡背面則鍍上一層鋁再刷漆,防水防霧等功效下降了很多,同時遇水后普鏡邊框容易泛紅,漆面容易脫落。此外,烤漆、印花、鋼化等加工工藝也影響著鏡子的價格。
