        山東通風管道怎么做熱處理?
        濟南通風管道消費的通風設備、風管及配件,依據其所處的環境和保送的氣體或粉塵的溫度、腐蝕性等,采用防腐資料制造或采取相應的防腐措施。建筑物內的熱風采暖、通風與空氣調理系統的風管布置,防火閥、排煙閥等的設置,均應契合國度現行有關建筑設計防火標準的請求。
         
          According to the environment and the temperature and corrosiveness of the gas or dust, the ventilation equipment, ducts and accessories consumed by Jinan ventilation pipeline are manufactured with anti-corrosive materials or take corresponding anti-corrosive measures. The arrangement of air pipes, fire valves and smoke exhaust valves in the hot air heating, ventilation and air conditioning systems in buildings should meet the requirements of the current national fire protection standards for architectural design.
         
          A. 通風管道及部件絕熱工程
         
          A. Ventilation Pipeline and Component Insulation Engineering
         
          ① 依據通風管道的斷面尺寸和所處的部位肯定絕熱固定釘的數量。
         
          The number of adiabatic fixing nails is determined according to the section size and location of the ventilation duct.
         
          ② 肯定固定釘位置后,先將通風管道壁上的塵土、油垢擦凈,再將粘接劑分別涂抹在通風管道壁面和保溫釘的粘接面上,稍后再將其粘接在一同。固定釘粘牢后應待12~24h后再覆鋪絕熱資料。
         
          (2) After confirming the location of the fixed nail, dust and grease on the wall of the ventilation pipeline are wiped off, then the adhesive is applied on the wall of the ventilation pipeline and the bonding surface of the insulation nail respectively, and then it is bonded together later. Fixed nails should be adhered to for 12 to 24 hours and then covered with adiabatic data.

          ③ 絕熱資料下料要精確,套裁下料,切割面要平齊,搭接處不要有縫隙。縱橫縫錯開,小塊資料應盡量用于通風管道上平面中間部位。
         
          (3) Precise cutting of adiabatic material, nesting cutting, smooth cutting surface and no gap in lap. When the longitudinal and transverse joints are staggered, small pieces of data should be used as far as possible in the middle part of the upper plane of the ventilation pipeline.
         
          ④ 明裝矩形通風管道絕熱應在四角加設鍍鋅鋼板包角,并用鍍鋅鐵絲固定或打包帶卡緊。
         
          (4) Galvanized steel sheet wrapping angle should be added at the four corners of the open rectangular ventilation duct, and fixed or clamped with galvanized iron wire or wrapping belt.
         
          ⑤ 絕熱層外纏玻璃絲布維護層時,先將玻璃絲布按通風管道斷面尺寸的大小裁成幅寬為200~400mm的長條,并卷成小卷備用。也可依據通風管道斷面尺寸的大小、直徑選用定型加工的不同幅寬的玻璃絲布。纏繞時,先用“∏”形鐵釘固定端頭,然后拉緊玻璃絲布纏繞。邊纏繞、邊整平,不得有折皺、翻邊等現象。圈與圈間兩邊搭接處的搭接寬度普通應為30~50mm。末端一定要用“∏”形鐵釘固定,否則容易松動、零落。
         
          _When winding the glass cloth maintenance layer outside the insulation layer, first cut the glass cloth into long strips with a width of 200-400 mm according to the size of the ventilation duct section, and roll it into small rolls for reserve. According to the size and diameter of ventilation duct section, different width glass cloth can also be selected for stereotyping. When winding, first fix the end with a -shaped nail, and then tighten the glass cloth. Edge winding, edge leveling, no wrinkling, flanging and other phenomena. The lap width of the lap between the circle and the two sides of the circle should be 30-50 mm. The end must be fixed with a -shaped nail, otherwise it is easy to loose and fall off.
         
          ⑥ 玻璃絲布表面面依據設計請求涂刷一道或兩道防火涂料,涂層應緊密、平均。
         
          _The surface of glass cloth should be coated with one or two fire-retardant coatings according to the design requirements. The coatings should be close and average.
         
          ⑦ 室外明露通風管道在保溫層外還應加一層鍍鋅鋼板或鋁板做維護外殼,外殼間搭接處采用拉鉚固定,搭接縫用密封膠密封。
         
          _A galvanized steel sheet or aluminium sheet should be added outside the insulation layer to maintain the outdoor exposed ventilation pipeline. The overlap between the shells should be fixed by riveting, and the overlap seam should be sealed with sealant.
