          鋁箔復合玻璃纖維管道
          Aluminum Foil Composite Fiberglass Pipeline
          鋁箔復合玻璃纖維風管是由超細玻璃棉制成的鐵板風管保溫材料。自1992年以來,超風管(玻璃纖維風管)已進入國內市場。雖然它已經在這個市場上經營了十多年,但是它的市場份額仍然很小,甚至在萎縮。
          Aluminum foil composite glass fiber duct is an insulating material of iron plate duct made of superfine glass wool. Since 1992, superductors (glass fibre ducts) have entered the domestic market. Although it has been operating in this market for more than ten years, its market share is still very small, even shrinking.
          1. 鋁箔復合玻璃纖維風管的優點
          1. Advantages of Aluminum Foil Composite Glass Fiber Wind Pipe
          1)吸收。由于其直接采用超細玻璃棉生產,材料相對松散,具有較好的吸聲性能。
          1) Absorption. Due to its direct use of ultra-fine glass wool production, the material is relatively loose and has good sound absorption performance.
          2)重量輕。它每平方米重約3公斤。
          2) Light weight. It weighs about 3 kilograms per square metre.
          但與鐵風管相比缺點也很多
          But compared with iron duct, it has many disadvantages.
          1)強度的差異。由于直接采用超細玻璃棉生產,承壓能力差,只能用于低壓、小風管。成品防護要求高,易被后期水電及裝修工程破壞。沒有清潔。
          1) The difference of strength. Because of the poor pressure-bearing capacity of superfine glass wool, it can only be used in low pressure and small air duct. The finished products have high protection requirements and are easily damaged by later hydropower and decoration projects. No cleaning.
          2)怕潮濕。超細玻璃棉具有很高的吸水率。如果表面密封不到位,尤其是開槽后,會吸收大量水分,降低絕緣性能和強度。
          2) Be afraid of dampness. Ultrafine glass wool has high water absorption. If the surface seal is not in place, especially after grooving, it will absorb a large amount of water and reduce the insulation performance and strength.
          纖維很容易飛。如果表面密封不到位,特別是開槽后,超細玻璃棉會導致纖維飛揚,影響人體健康。
          Fiber flies easily. If the surface seal is not in place, especially after grooving, ultra-fine glass wool will cause fibers flying, affecting human health.
          4)抗風能力強。絕對表面粗糙度可達0.9-1.1mm,一般要求單位功率增加10%,增加能耗。
          4) Strong wind resistance. Absolute surface roughness can reach 0.9-1.1 mm, which generally requires 10% increase in unit power and energy consumption.

          鋁箔聚氨酯導管
          Aluminum foil polyurethane conduit
          鋁箔聚氨酯風管是中間絕緣材料是聚氨酯,兩側復合鋁箔制成的片狀風管。空氣管的主要特點之一是光,但火性能不能滿足需求是其大的短缺,高層建筑大火“代碼”和“民用建筑火災代碼”規定,通風管類的材料必須不燃材料。夾芯風管只能達到高B1水平,其配件和膠水為有機材料,高也只能達到B1水平,不符合標準。夾芯風管強度差,抗壓能力差也是其主要缺點之一。

          Aluminum foil polyurethane air duct is a flake air duct made of polyurethane as intermediate insulating material and composite aluminum foil on both sides. One of the main characteristics of air pipes is light, but the biggest shortage is that the fire performance can not meet the needs of the country. The "code" and "fire code for civil buildings" stipulate that the materials of ventilation pipes must be non-combustible. Sandwich duct can only reach the highest B1 level, its accessories and glue are organic materials, and the highest B1 level can only be reached, which does not meet the national standards. The strength of sandwich duct is poor and its compression resistance is also one of its main shortcomings.
          鋁箔復合酚醛管道
          Aluminum Foil Composite Phenolic Pipeline
          酚醛管道由酚醛絕緣材料和兩側復合鋁箔制成。
          The phenolic pipeline is made of phenolic insulating material and composite aluminum foil on both sides.
          酚醛管道的優點是重量輕,缺點明顯,強度差,易粉化,易分層的鋁箔和酚醛,發泡過程中使用大量強酸,膠水是有機的,含有甲醛,不環保。
          The advantages of phenolic pipeline are light weight, obvious shortcomings, poor strength, easy pulverization, easy layering of aluminum foil and phenolic aldehyde, using a large number of strong acids in the foaming process, glue is organic, containing formaldehyde, not environmentally friendly.

          顏色鋼導管
          Colour steel conduit
          彩鋼板管分為單彩鋼和雙彩鋼兩種,單彩鋼是將原來的外部超細玻璃棉在里面,外面是一層顏色鋼鐵,在超細玻璃棉層,雙層彩鋼是鐵皮風管保溫棉外一層金屬保護,技術上比鐵管或鐵管道并沒有太大的創新,實際上。改進點是用PVC插條代替咬口和法蘭,絕緣棉和彩鋼板復合成型,無需二次絕緣。
          Colored steel tube is divided into two kinds: single color steel and double color steel. Single color steel is the original external ultra-fine glass wool inside, the outside is a layer of color steel, in the ultra-fine glass wool layer, double color steel is a layer of metal protection outside the insulation cotton of iron sheet air duct, there is not much innovation in technology than iron pipe or iron pipe, in fact. The improvement point is to use PVC insert instead of bite and flange, insulating cotton and coloured steel plate composite moulding, without secondary insulation.
