鐵皮風(fēng)管應(yīng)盡可能按直線布置。這一條要求對(duì)任何風(fēng)管系統(tǒng)的布置都是重要的準(zhǔn)則。直線布置的風(fēng)管系統(tǒng)，在運(yùn)行能耗和初投資兩方面都是低的。從的觀點(diǎn)分析，空氣總是"希望"走直線，這將減少能耗。從費(fèi)用的觀點(diǎn)分析，直管段的費(fèi)用比各種彎頭等管件要少很多。

Iron sheet air ducts should be arranged as straight as possible. This requirement is an important criterion for the layout of any duct system. The straight-line layout of the air duct system has low operating energy consumption and initial investment. From the perspective of energy conservation, air always "hopes" to go straight, which will reduce energy consumption. From a cost perspective, the cost of straight pipe sections is much lower than that of various elbows and other fittings.

開裂是鐵皮風(fēng)管在使用的過程中常見的問題之一。實(shí)際上，鐵皮風(fēng)管專用膠的粘接強(qiáng)度很高，在安裝使用中，如果發(fā)現(xiàn)部份開裂現(xiàn)象，濟(jì)南鐵皮風(fēng)管加工人員提醒，這一般是因?yàn)椋?/p>

Cracking is one of the common problems in the use of iron sheet air ducts. In fact, the adhesive strength of the iron sheet air duct special adhesive is very high. If some cracks are found during installation and use, Jinan iron sheet air duct processing personnel remind that this is generally because:

1、風(fēng)管板質(zhì)量不合格，強(qiáng)度差，變形度大，制作成風(fēng)管后尺寸穩(wěn)定性差，易開裂；

1. The air duct board has unqualified quality, poor strength, large deformation, poor dimensional stability after being made into an air duct, and is prone to cracking;

2、制作與施工中應(yīng)采用專用膠，但大多數(shù)仿制企業(yè)不知道或不懂得專用膠的配制，認(rèn)為氧化鎂加鹵水就是膠粘劑，這種膠粘劑制作與安裝的風(fēng)管肯定開裂；

2. Special adhesives should be used in production and construction, but most imitation enterprises do not know or understand the preparation of special adhesives. They believe that magnesium oxide and brine are adhesives, and the air ducts produced and installed with this adhesive will definitely crack;

3、鐵皮風(fēng)管施工專用膠的配制不能太少或者太稠。粘接時(shí)缺膠或膠體過稠，以及伸縮節(jié)布置不合理都易造成鐵皮風(fēng)管開裂。

3. The preparation of special adhesive for the construction of iron sheet air ducts should not be too small or too thick. Lack of adhesive or excessive viscosity during bonding, as well as improper arrangement of expansion joints, can easily cause cracking of the iron sheet air duct.

發(fā)現(xiàn)鐵皮風(fēng)管開裂可以用修補(bǔ)膠修補(bǔ)。修補(bǔ)方法為：

Cracks in the iron sheet air duct can be repaired with repair glue. The repair method is:

1）在開裂線50mm周圍用砂皮打磨，并除去塵粒；

1) Grind with sand around the crack line 50mm and remove dust particles;

2）將修補(bǔ)膠壓入開裂縫；

2) Press the repair adhesive into the crack;

3）在鐵皮風(fēng)管開裂處貼上玻布。用修補(bǔ)膠修理平整、美觀。

3) Apply glass cloth to the cracked area of the iron sheet air duct. Repair flat and aesthetically pleasing with repair adhesive.
