螺旋风管应该如何面对寒冷天气?

  热胀冷缩对于风管是有一定损害的,今天小编来说说,在北方寒冷地区或者是进入冬季,螺旋风管应该如何面对这一麻烦。
  The expansion and contraction of heat has certain damage to the air duct. Today, let's talk about how the spiral air duct should face this trouble in the cold area in the north or in winter.
  首先对于保温材料的选择,要选择保温性能好的,保温材料的规格应符合风管系统所使用的,还应当符合风管的设计要求,使用的保温材料要有合格证等质量合格证件,以保证使用时能有效的保护风管,使其在冬天使用时不易损坏。洁净风管一般选择难燃闭孔橡塑海绵保温材料,排烟风管一般采用不燃的铝箔玻璃棉板。这两种材料使用比较普遍,保温性能比较好。
  First of all, for the selection of thermal insulation materials, the ones with good thermal insulation performance shall be selected, and the specifications of thermal insulation materials shall meet the requirements of the air duct system, as well as the design requirements of the air duct. The thermal insulation materials used shall have quality certificates such as certificates to ensure that the air duct can be effectively protected in use, so that it is not easy to be damaged in winter. The clean air duct is generally made of fire-resistant closed cell rubber plastic sponge insulation material, and the smoke exhaust air duct is generally made of non combustible aluminum foil glass wool board. These two materials are widely used and have good heat preservation performance.

  其次使用保温材料包裹螺旋风管时,切割时,下料要准确,切割面尽量要平齐,这样粘接时才能确保粘接紧密,切料时,要使水平垂直面搭接处以短面两头顶在大梁上。
  Secondly, when wrapping the spiral air duct with thermal insulation materials, the cutting shall be accurate, and the cutting surface shall be as flat as possible, so as to ensure the tight bonding. When cutting, the short ends of the overlapping part of the horizontal and vertical surfaces shall be placed on the girder.
  在用保温材料包裹螺旋风管前涂胶时,胶的厚度要均匀,还有涂胶时不能有胶流淌,对保温材料进行铺覆时,这样才能有效的保证粘接时粘接的地方粘接紧密了。粘接的地方才不会有空鼓出现,也不会有裸露在外面的风管。
  Finally, when the insulation material is used to wrap the spiral air duct, the thickness of the adhesive shall be uniform, and there shall be no glue flowing when the adhesive is applied. When the insulation material is laid, it can effectively ensure that the bonding place is tightly bonded during the bonding. There will be no hollowing in the bonding area and no exposed air duct.
