鋁箔復(fù)合玻璃纖維管道
Aluminum Foil Composite Fiberglass Pipeline
鋁箔復(fù)合玻璃纖維風(fēng)管是由超細(xì)玻璃棉制成的鐵板風(fēng)管保溫材料。自1992年以來(lái)，超風(fēng)管(玻璃纖維風(fēng)管)已進(jìn)入國(guó)內(nèi)市場(chǎng)。雖然它已經(jīng)在這個(gè)市場(chǎng)上經(jīng)營(yíng)了十多年，但是它的市場(chǎng)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(fù)合玻璃纖維風(fēng)管的優(yōu)點(diǎn)
1. Advantages of Aluminum Foil Composite Glass Fiber Wind Pipe
1)吸收。由于其直接采用超細(xì)玻璃棉生產(chǎn)，材料相對(duì)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(fēng)管相比缺點(diǎn)也很多
But compared with iron duct, it has many disadvantages.
1)強(qiáng)度的差異。由于直接采用超細(xì)玻璃棉生產(chǎn)，承壓能力差，只能用于低壓、小風(fēng)管。成品防護(hù)要求高，易被后期水電及裝修工程破壞。沒(méi)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(xì)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(huì)吸收大量水分，降低絕緣性能和強(qiáng)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(xì)玻璃棉會(huì)導(dǎo)致纖維飛揚(yáng)，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(fēng)能力強(qiáng)。絕對(duì)表面粗糙度可達(dá)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(dǎo)管
Aluminum foil polyurethane conduit
鋁箔聚氨酯風(fēng)管是中間絕緣材料是聚氨酯，兩側(cè)復(fù)合鋁箔制成的片狀風(fēng)管?？諝夤艿闹饕攸c(diǎn)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(zāi)代碼”規(guī)定,通風(fēng)管類的材料必須不燃材料。夾芯風(fēng)管只能達(dá)到高B1水平，其配件和膠水為有機(jī)材料，高也只能達(dá)到B1水平，不符合標(biāo)準(zhǔn)。夾芯風(fēng)管強(qiáng)度差，抗壓能力差也是其主要缺點(diǎn)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(fù)合酚醛管道
Aluminum Foil Composite Phenolic Pipeline
酚醛管道由酚醛絕緣材料和兩側(cè)復(fù)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(yōu)點(diǎn)是重量輕，缺點(diǎn)明顯，強(qiáng)度差，易粉化，易分層的鋁箔和酚醛，發(fā)泡過(guò)程中使用大量強(qiáng)酸，膠水是有機(jī)的，含有甲醛，不環(huán)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(dǎo)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(lái)的外部超細(xì)玻璃棉在里面,外面是一層顏色鋼鐵,在超細(xì)玻璃棉層,雙層彩鋼是鐵皮風(fēng)管保溫棉外一層金屬保護(hù),技術(shù)上比鐵管或鐵管道并沒(méi)有太大的創(chuàng)新,實(shí)際上。改進(jìn)點(diǎn)是用PVC插條代替咬口和法蘭，絕緣棉和彩鋼板復(fù)合成型，無(wú)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.
