铝合金卷帘门的使用在我们的日常生活越来越常见，不过有的用户利用的好得到了好的使用效果，反之有的用户利用率不高。那么铝合金卷帘门的利用率怎么提高？

　　The use of aluminum alloy rolling shutter doors is more and more common in our daily life, but some users make good use of it and get good use effect, whereas some users have low utilization rate. So how to improve the utilization rate of aluminum alloy rolling door?

　　拧紧所有松动的螺钉：

　　在卷帘门上，请检查将所有松动的螺钉固定在一起的铰链，并更换损坏的铰链。有时门会向一侧下沉，通常可以通过修理铰链来纠正。如果螺孔变大，请更换相同直径但更长的螺钉，并在中空纤维棒上涂上木工胶。然后装上新螺丝。如果铰链处的木头有裂纹，请取下铰链，用填孔剂填充裂纹和螺孔，填孔剂干燥后更换铰链。

　　Tighten all loose screws:

　　On rolling shutter doors, check hinges holding all loose screws together and replace damaged hinges. Sometimes the door sinks to one side, which can usually be corrected by fixing the hinge. If the screw hole becomes larger, replace the longer screw with the same diameter and apply woodworking glue to the hollow fiber rod. Then put in the new screws. If the wood at the hinge is cracked, remove the hinge, fill the cracks and screw holes with a pore-filler, and replace the hinge after the pore-filler dries.

　　检查弹簧：

　　卷帘门两侧的弹簧由滑轮上的弹簧缆线控制。为了调节弹簧的弹性，请拉长穿过门上板的缆线，然后在末端再次打结以保持新的弹性。如果卷门中间只有一个扭簧，请不要试图修理，因为弹簧的弹性太大，可能会导致你受伤。对于使用这种弹簧的门，您应该致电维护服务部门寻求帮助。

　　Check spring:

　　The springs on both sides of the rolling shutter door are controlled by the spring cable on the pulley. To adjust the spring's elasticity, stretch the cable through the upper panel of the door, and then tie the end again to maintain the new elasticity. If there is only one torsion spring in the middle of the door, do not attempt to repair it, as the spring is too elastic and may cause injury. For doors that use these springs, you should call professional maintenance services for assistance.

　　检查金属轨道：

　　检查铝合金卷帘门金属轨道，并检查将轨道固定在墙上的安装支架。如果支架松动，拧紧螺栓或螺钉并关闭铝合金卷帘门。检查车库的轨道是否有凹痕、弯曲或变平。如有损坏，请用橡胶锤或废木垫锤敲击这些地方。如果轨道严重损坏须更换它。

　　Check metal rails:

　　Check the aluminum alloy rolling door metal track and the mounting bracket that holds the track to the wall. If the bracket is loose, tighten the bolts or screws and close the aluminum alloy rolling shutter door. Check the garage tracks for dents, bends, or flattens. If damaged, hit these areas with a rubber hammer or scrap wood pad hammer. Replace the track if it is badly damaged.

　　另外，铝合金卷帘门的密度越高，隔音的功能就会越强，所以如果您想要自家的卷帘门有个好的隔音功能，那么需要做的事情还有很多。更多就来网站www.jnhsjlm.com咨询吧。
