Aluminum Foil Composite Fiberglass Pipeline

　　铝箔复合玻璃纤维风管是由超细玻璃棉制成的铁板风管保温材料。自1992年以来，超风管(玻璃纤维风管)已进入国内市场。虽然它已经在这个市场上经营了十多年，但是它的市场份额仍然很小，甚至在萎缩。

　　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. 铝箔复合玻璃纤维风管的优点

　　1. Advantages of Aluminum Foil Composite Glass Fiber Wind Pipe

　　1)吸收。由于其直接采用超细玻璃棉生产，材料相对松散，具有较好的吸声性能。

　　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)重量轻。它每平方米重约3公斤。

　　2) Light weight. It weighs about 3 kilograms per square metre.

　　但与铁风管相比缺点也很多

　　But compared with iron duct, it has many disadvantages.

　　1)强度的差异。由于直接采用超细玻璃棉生产，承压能力差，只能用于低压、小风管。成品防护要求高，易被后期水电及装修工程破坏。没有清洁。

　　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)怕潮湿。超细玻璃棉具有很高的吸水率。如果表面密封不到位，尤其是开槽后，会吸收大量水分，降低绝缘性能和强度。

　　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.

　　纤维很容易飞。如果表面密封不到位，特别是开槽后，超细玻璃棉会导致纤维飞扬，影响人体健康。

　　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)抗风能力强。绝对表面粗糙度可达0.9-1.1mm，一般要求单位功率增加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.

　　铝箔聚氨酯导管

　　Aluminum foil polyurethane conduit

　　铝箔聚氨酯风管是中间绝缘材料是聚氨酯，两侧复合铝箔制成的片状风管。空气管的主要特点之一是光,但火性能不能满足需求是其大的短缺,高层建筑大火“代码”和“民用建筑火灾代码”规定,通风管类的材料必须不燃材料。夹芯风管只能达到高B1水平，其配件和胶水为有机材料，高也只能达到B1水平，不符合标准。夹芯风管强度差，抗压能力差也是其主要缺点之一。

　　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.

　　铝箔复合酚醛管道

　　Aluminum Foil Composite Phenolic Pipeline

　　酚醛管道由酚醛绝缘材料和两侧复合铝箔制成。

　　The phenolic pipeline is made of phenolic insulating material and composite aluminum foil on both sides.

　　酚醛管道的优点是重量轻，缺点明显，强度差，易粉化，易分层的铝箔和酚醛，发泡过程中使用大量强酸，胶水是有机的，含有甲醛，不环保。

　　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.

　　颜色钢导管

　　Colour steel conduit

　　彩钢板管分为单彩钢和双彩钢两种,单彩钢是将原来的外部超细玻璃棉在里面,外面是一层颜色钢铁,在超细玻璃棉层,双层彩钢是铁皮风管保温棉外一层金属保护,技术上比铁管或铁管道并没有太大的创新,实际上。改进点是用PVC插条代替咬口和法兰，绝缘棉和彩钢板复合成型，无需二次绝缘。

　　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.
