随着人们在装饰品中的味道的提高,家庭中的几千元实木门的选择真的增加了很多颜色。一匹良好的马匹和一个良好的马鞍和一对带有一对两个奇的元的铰链都是轻盈的。很难。很难识别真假铜轴承铰链。现在市场上有许多假轴承铰链,它们上有几个铜环,看起来像轴承铰链。普通人只想通过拆卸铰链来看看它是否有轴承。让我告诉你一个小伎俩。您可以一目了然地告诉您可以将铰链略微打开至90度或小于90度。如果握住其中一个铰链,另一个将快速打开或关闭,并且可以拧紧或松开铰链。它是假的,它没有内部的轴承。 If it opens or closes slowly, it feels very smooth. It is light and light, which means there is a bearing inside, which is a real bearing hinge. One way to identify whether the hinge is copper is to use a magnet to test the other way is to grind a sharp corner of the hinge on the concrete floor a few times. There is no yellow at the top corners, which is fake; the top corners that are ground out are also yellow, but the hinges are lighter, and they are made of copper alloy. Finally, pay attention to the thickness of the hinge. Of course, the thicker one is better. As long as you pass these inspections, the hinge you bought must be a genuine copper ‘bearing hinge.’
