一、铁皮风管

I. Iron duct

1、铁皮风管长处

1. Advantages of iron duct

1) 强度高,能承受3kPa的风压,可满意高中低压风体系的运用。

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) 可现场加工,运送成本低,调整方便,不影响工期。

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

二、铝箔复合玻纤风管

II. Aluminum Foil Composite Glass Fiber Ventilator

铝箔复合玻纤风管直接用铁皮风管的保温资料-超细玻璃棉制造而成。

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

1、铝箔复合玻纤风管长处

1. Advantages of Aluminum Foil Composite Glass Fiber Wind Pipe

1) 吸声。因其直接用超细玻璃棉制造,原料比较松懈,有较好的吸声功能。

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) 重量轻。每平方米重量3kg左右。

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

三、铝箔聚氨酯风管

III. Aluminum foil polyurethane duct

铝箔聚氨酯风管是中间保温资料是聚氨酯、两头复合铝箔为板材制成的风管。三文治风管的一大特点是质轻,但防火功能达不到国家要求是它较大的不足,国家《高层建筑防火标准》和《民用建筑防火标准》均规定通风管道资料必须用A级不燃资料制造。三文治风管较高只能达到B1级,而它的配件及胶水为有机资料,较高也只能达到B1级,不符合国家标准。三文治风管强度差、承压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、铝箔复合酚醛风管

IV。 Aluminum foil composite phenolic duct

酚醛风管是以酚醛为保温资料、两头复合铝箔为板材而制造成的风管。

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

酚醛风管的长处是重量轻,缺陷也显而易见,强度差、易粉化、铝箔与酚醛易分层,在发泡过程中运用大量强酸,胶水为有机胶,含甲醛,不环保。

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、彩钢板风管

V. Coloured Steel Plate Ventilation Pipes

彩钢板风管分为单面彩钢和双面彩钢两种,单面彩钢就是把本来的外部超细玻璃棉移到了内部,也就是外面一层彩钢,里面一层超细玻璃棉。

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.

双面彩钢就是在铁皮风管的保温棉外再做一层铁皮维护,在技术上较之铁皮风管并没有太大的创新,实际上还是铁皮风管。改进点是用PVC插条取代了咬口和法兰,保温棉与彩钢板一次复合成型,不需二次保温。

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.
