热胀冷缩关于风管是有一定损伤的，今天小编来说说，在北方冰冷地域或者是进入冬季，螺旋风管应该如何面对这一费事。

Thermal expansion and cold contraction have certain damage to the air duct. Today, let's talk about how the spiral air duct should face this trouble in cold areas in the north or in winter.

关于保温资料的选择，要选择保温性能好的，保温资料的规格应契合风管系统所运用的，还应当契合风管的设计请求，运用的保温资料要有合格证等质量合格证件，以保证运用时能有效的维护风管，使其在冬天运用时不易损坏。

First of all, for the selection of thermal insulation materials, the ones with good thermal insulation performance shall be selected. The specifications of thermal insulation materials shall conform to the application of air duct system and the design requirements of air duct. The applied thermal insulation materials shall have quality certificates such as certificate, so as to ensure that the air duct can be effectively maintained during operation and not easy to be damaged during operation in winter.

干净风管普通选择难燃闭孔橡塑海绵保温资料，排烟风管普通采用不燃的铝箔玻璃棉板。这两种资料运用比拟普遍，保温性能比拟好。

Flame retardant closed cell rubber plastic sponge insulation material is generally selected for clean air duct, and non combustible aluminum foil glass wool board is generally used for smoke exhaust air duct. These two materials are widely used and have good thermal insulation performance.

其次运用保温资料包裹螺旋风管时，切割时，下料要精确，切割面尽量要平齐，这样粘接时才干确保粘接严密，切料时，要使程度垂直面搭接处以短面两头顶在大梁上。

Secondly, when the spiral air duct is wrapped with thermal insulation data, the blanking shall be accurate and the cutting surface shall be flush as far as possible, so as to ensure tight bonding during bonding. When cutting, the two ends of the short surface at the overlap of the vertical surface shall be pushed on the girder.

在用保温资料包裹螺旋风管前涂胶时，胶的厚度要平均，还有涂胶时不能有胶流淌，对保温资料停止铺覆时，这样才干有效的保证粘接时粘接的粘接严密了。粘接的才不会有空鼓呈现，也不会有暴露在外面的风管。

Finally, when applying glue before wrapping the spiral air duct with thermal insulation data, the thickness of the glue shall be average, and there shall be no glue flow when applying glue. When the thermal insulation data is stopped, it can effectively ensure that the central bonding during bonding is tight. There will be no hollowing in the center of the bonding, and there will be no exposed air duct.
