一、鐵皮風管

I. Iron duct

1、鐵皮風管長處

1. Advantages of iron duct

1) 強度高，能承受3kPa的風壓，可滿意高中低壓風體系的運用。

1) It has high strength and can withstand wind pressure of 3kPa. It can satisfy the application of high, medium and low pressure wind system.

2) 可現(xiàn)場加工，運送成本低，調(diào)整方便，不影響工期。

2) It can be processed on site, with low transportation cost and convenient adjustment, without affecting the construction period.

二、鋁箔復合玻纖風管

II. Aluminum Foil Composite Glass Fiber Ventilator

鋁箔復合玻纖風管直接用鐵皮風管的保溫資料-超細玻璃棉制造而成。

Aluminum foil composite glass fiber duct is directly made of superfine glass wool, which is the insulation material of iron sheet duct.

1、鋁箔復合玻纖風管長處

1. Advantages of Aluminum Foil Composite Glass Fiber Wind Pipe

1) 吸聲。因其直接用超細玻璃棉制造，原料比較松懈，有較好的吸聲功能。

1) sound absorption. Because it is directly made of superfine glass wool, the raw material is relatively loose and has better sound absorption function.

2) 重量輕。每重量3kg左右。

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

三、鋁箔聚氨酯風管

III. Aluminum foil polyurethane duct

鋁箔聚氨酯風管是中間保溫資料是聚氨酯、兩頭復合鋁箔為板材制成的風管。三文治風管的一大特點是質(zhì)輕，但防火功能達不到要求是它較大的不足，《高層建筑防火標準》和《民用建筑防火標準》均規(guī)定通風管道資料必須用A級不燃資料制造。三文治風管較高只能達到B1級，而它的配件及膠水為有機資料，較高也只能達到B1級，不符合標準。三文治風管強度差、承壓能力差也是它的一大缺陷。

Aluminum foil polyurethane air duct is a kind of air duct made of polyurethane and composite aluminum foil. Sandwich air duct is characterized by light weight, but its biggest shortcoming is that its fire protection function can not meet the national requirements. National Fire Protection Standard for High-rise Buildings and Fire Protection Standard for Civil Buildings both stipulate that the information of ventilation duct must be manufactured with Class A non-combustible materials. Sandwich air duct can only reach level B1 at the highest level, while its accessories and glue are organic materials, and can only reach level B1 at the highest level, which does not meet the national standards. Sandwich air duct is also a major defect of its poor strength and pressure bearing capacity.

四、鋁箔復合酚醛風管

IV. Aluminum foil composite phenolic duct

酚醛風管是以酚醛為保溫資料、兩頭復合鋁箔為板材而制造成的風管。

Phenolic air duct is a kind of air duct made of phenolic as insulation material and composite aluminum foil at both ends.

酚醛風管的長處是重量輕，缺陷也顯而易見，強度差、易粉化、鋁箔與酚醛易分層，在發(fā)泡過程中運用大量強酸，膠水為有機膠，含甲醛，不。

The advantages of phenolic duct are light weight, obvious defects, poor strength, easy pulverization, easy stratification of aluminum foil and phenolic, the use of a large number of strong acids in the foaming process, glue is organic glue, containing formaldehyde, not environmentally friendly.

五、彩鋼板風管

V. Coloured Steel Plate Ventilation Pipes

彩鋼板風管分為單面彩鋼和雙面彩鋼兩種，單面彩鋼就是把本來的外部超細玻璃棉移到了內(nèi)部，也就是外面一層彩鋼，里面一層超細玻璃棉。

Colored steel air duct is divided into two kinds: single-side colored steel and double-side colored steel. Single-side colored steel is to move the original external ultra-fine glass wool to the inside, that is, a layer of colored steel outside, and a layer of ultra-fine glass wool inside.

雙面彩鋼就是在鐵皮風管的保溫棉外再做一層鐵皮維護，在技術(shù)上較之鐵皮風管并沒有太大的創(chuàng)新，實際上還是鐵皮風管。改進點是用PVC插條取代了咬口和法蘭，保溫棉與彩鋼板一次復合成型，不需二次保溫。

Double-sided color steel is to do a layer of iron maintenance outside the insulation cotton of the iron duct. Compared with the iron duct, there is not much innovation in technology. In fact, it is still the iron duct. The improvement point is to replace bite and flange with PVC insert. The insulation cotton and coloured steel plate are formed at one time without secondary insulation.
