电动卷帘门维修质量上要把握四个字！

电动卷帘门维修在质量上要把握四个字：牢、平、准、密。掌握了这四个字在体会一下，可以减少消费者不必要的浪费。下面济南电动卷帘门安装维修厂家为您解析。

The maintenance of electric roller shutter door should grasp four words in quality: firm, flat, accurate and dense. Mastering these four words can reduce consumers' unnecessary waste. Next, Jinan electric roller shutter door installation and maintenance manufacturer will analyze for you.

1、牢是指要牢固。

1. Firm means firm.

框、扇四角通常采取焊接方式，国标要求角强度平均值需达到3000N以上。这方面需要有正规焊接设备才能有保证，马路边上的小加工店基本上没保证。另外就是连接件、紧固件要牢固，由于塑的主材料是PVC，而其断面壁厚通常在2.3mm左右，不能够承受像平开合页等五金件的。它们需要内部有足够厚度产品衬支撑的，所以在购买前先要仔细观察厂家是否存在缺斤少量或偷工减料的可能，在做成成品后不太容易检查到内部产品衬的厚度。

The four corners of frame and fan are usually welded, and the national standard requires that the average angular strength should reach more than 3000N. In this respect, we need to have formal welding equipment to guarantee it. The small processing shop on the road side basically does not guarantee it. In addition, connectors and fasteners should be firm. Because the main material of plastic is PVC, and its section wall thickness is usually about 2.3mm, it can not bear hardware such as flat hinges. They need to be supported by the product lining with sufficient thickness inside, so before purchasing, carefully observe whether the manufacturer has the possibility of missing a small amount of weight or cutting corners. It is not easy to check the thickness of the internal product lining after it is finished.

2、平是指要平整。

2. Flat means flat.

它包括焊角不能高低错位、两拼接不能高低不平。平主要体现在外观上，也是给我们视觉带来美感的重要项目。平在国标中也有具体体现，比如：焊角的高低差应在0.3mm范围内等。这种情况不了解国标也无所谓，但你要看过他的样，然后要求其外观质量达到样即可，一般商家展示的样质量还是OK的。

It includes that the weld fillet shall not be staggered, and the two splices shall not be uneven. Flat is mainly reflected in the appearance, and is also an important item that brings us a sense of beauty. The level is also embodied in the national standard, for example, the height difference of weld fillet should be within 0.3mm. It doesn't matter if you don't know the national standard, but you need to look at his samples, and then ask the appearance quality to meet the sample. Generally, the quality of the samples displayed by the merchants is OK.

3、准是指准确。

3. Accurate means accurate.

主要是尺寸准确。它包括在实际测量洞口时尺寸以及后来安装后的扇与框的尺寸，实际中尺寸不准确往往会影响到的开启、的密封性等。用户可以简单的知道，普通框与扇搭接一般在8-10mm，如果尺寸过小(如4-5mm)，其密封性能另人质疑。

The main reason is accurate size. It includes the actual measurement of the size of the opening and the size of the fan and frame after installation. In practice, inaccurate size often affects the opening and sealing. Users can simply know that the overlap of common frame and fan is generally 8-10mm. If the size is too small (such as 4-5mm), its sealing performance is questionable.

4、密是指密封性能。

4. Tightness refers to sealing performance.

上面谈到尺寸会影响密封，这里讲厂家购买的不合格配附件一样会影响到密封。如有些厂家用的劣质橡皮条，结果不出半年就开始收缩。

The size mentioned above will affect the sealing, and the unqualified accessories purchased by the manufacturer will also affect the sealing. For example, the inferior rubber strips used by some manufacturers began to shrink within half a year.
