pp風管是什么材質的

What is the material of PP air duct

如今許多人到開展室內裝修的那時候，都是采用PP風管，許多人對Pp通風風管的規定很高,包含材料,價格等各個***域。盡管小小Pp風管很不值一提可是卻在家居裝修中具有了尤為重要的功效。***家很關注PP通風風管的材料,那麼如今銷售市場上的Pp通風風管都選用了什么哪些材料呢?

Nowadays, many people use PP air duct when they carry out interior decoration. Many people have very high regulations on PP air duct, including materials, prices and other fields. Although the small PP air duct is not worth mentioning, it has a particularly important effect in home decoration. People are very concerned about PP ventilation duct materials, so what materials are used for PP ventilation duct in the sales market now?

管事實上是指選用聚丙稀這種材料制做而成的,關鍵運用于房屋建筑房間內熱水管供貨系統軟件,相對性于別的材料的管件來講,其具備十分非常***的***勢:

In fact, the pipe is made of polypropylene, which is mainly used in the hot water supply system software in the room of housing construction. Compared with the pipe fittings made of other materials, it has very good advantages:

PP風管的關鍵材料是聚丙稀，這是由丙烯聚合物而制取的這種熱塑性樹脂。無毒性、無臭、無氣味的奶白色高結晶體的高聚物，相對密度只能4. 95--"4. 91g/cm3，別的材料的凈重都不如它輕。值得一提的是，它的有機化學可靠性非常***，除能被濃硫酸、濃硝酸腐蝕外，對其他各種各樣化學藥品都穩定，但低含量的脂肪烴、芳香烴和氯化烴等能使聚丙稀變軟和溶脹，一起它的有機化學可靠性隨晶粒***小的提升還逐步提高，因此聚丙稀合適制做各種各樣化工管道和零配件，耐腐蝕實際效果******。

The key material of PP air duct is polypropylene, which is a thermoplastic resin made of propylene polymer. The non-toxic, odorless and odorless milk white high knot crystal polymer has a relative density of only 4.95 -- "4.91g/cm3, and the net weight of other materials is not as light as it. It is worth mentioning that its organic chemical reliability is very good. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is stable for all kinds of other chemicals, but the low content of aliphatic hydrocarbon, aromatic hydrocarbon and chlorinated hydrocarbon can make polypropylene soften and swell. Together, its organic chemical reliability increases gradually with the increase of grain size, so polypropylene is suitable for making all kinds of chemicals Engineering pipeline and spare parts, good corrosion resistance.

PP風管材料的***性：

Properties of PP air duct material:

1、不生銹:PP風管閘閥可在挺***的溫度范圍之內承擔pH,范疇在1～13的高濃的酸和堿的浸蝕。

1. No rust: PP air pipe gate valve can bear the pH within a large temperature range, and the range is 1-13 with high concentration of acid and alkali.

2、抗磨損、不積垢:PP風管閘閥及管材內腔勻稱光潔,流動性摩擦阻力小而且不積垢。

2. Wear resistance and no scaling: the inner cavity of PP air pipe gate valve and pipe is well proportioned and smooth, with small flow friction resistance and no scaling.

3、減少震動和噪音:PP風管閘閥具備***質的隔音性***性,可明顯降低由液體流動性造成的震動和噪音。

3. Reduce vibration and noise: PP air pipe gate valve has high-quality sound insulation characteristics, which can significantly reduce vibration and noise caused by liquid fluidity.

4、防寒裂:PP風管原材料延展性***質促使管件和管材橫截面可隨之凍脹的液體一塊兒澎漲而不容易脹裂。

4. Cold crack prevention: the high ductility of PP air duct raw materials makes the cross section of pipe fittings and pipes rise together with the frost heaving liquid, which is not easy to crack.

5、防冷凝水,熱損害少:PP風管原材料為欠佳熱電導體,可降低冷凝水問題并降低熱損少。

5. Anti condensation water, less heat damage: PP air duct raw material is poor thermal conductor, which can reduce the problem of condensation water and reduce the heat loss.

6、安裝操作:PP通風風管很輕,安裝操作便捷,而且具備可焊性。

6. Installation and operation: PP ventilation duct is light, easy to install and operate, and has weldability.

一、PP風管就是說用以氣體輸送機和遍布的管路系統軟件，通風風管可按橫截面樣子和材料歸類，按橫截面樣子，通風風管可分成環形通風風管，矩形框通風風管，扁圓通風風管等多種，至少環形通風風管摩擦阻力小的高寬比規格***，制做繁雜，因此運用以矩形框通風風管主導。按材料，通風風管可分成金屬材料通風風管，復合風管，高分子材料通風風管。至少金屬材料通風風管就是說用各種各樣金屬復合材料制做的通風風管，常見的包含鍍鋅鋼板和不銹鋼板等。

I. PP air duct is used for gas conveyor and all over the pipeline system software. The ventilation air duct can be classified according to the cross-section appearance and materials. According to the cross-section appearance, the ventilation air duct can be divided into ring ventilation air duct, rectangular frame ventilation air duct, flat round ventilation air duct, etc. at least, the height width ratio of the ring ventilation air duct with small friction resistance is large and the manufacture is complicated. Therefore, the rectangular frame is used The ventilation duct is dominant. According to the material, the ventilation air duct can be divided into metal material ventilation air duct, composite air duct and polymer material ventilation air duct. At least, metal ventilation duct is a kind of ventilation duct made of various metal composite materials, including galvanized steel plate and stainless steel plate.

二、PP通風風管由各種各樣無機物原材料復合型而成，按構成不一樣分成多種多樣，但多見輕質混凝土，多孔結構，傳熱系數***的原材料，不生銹，可在挺***的溫度范圍之內承擔pH，范疇在1~13的高濃的酸和堿的浸蝕，抗磨損、不積垢，以及管材內腔勻稱光潔，流動性摩擦阻力小而且不容易積垢。

II. PP ventilation air duct is composed of various inorganic raw materials, which can be divided into various types according to their composition. However, light concrete, porous structure, raw materials with high heat transfer coefficient, which are not rusty, can bear the pH value in a large temperature range, and the corrosion of acid and alkali with high concentration in the range of 1-13, which are resistant to wear and scale, and the inner cavity of the pipe is even and smooth, flowing Sexual friction resistance is small and not easy to scale.

三、減少震動和噪音：PP風管具備很***的隔音性***性，可更顯降低由液體流動性造成的震動和噪音，防寒裂，原材料延展性***質促使管件和管材橫截面可隨之凍脹的液體一塊兒澎漲而不容易脹裂，防冷凝水，熱損害少，原材料為欠佳熱電導體，可降低冷凝水問題并降低熱損少。

III. reduce vibration and noise: PP air duct has good sound insulation characteristics, which can significantly reduce the vibration and noise caused by liquid fluidity, prevent cold cracking. The high ductility of raw materials enables the cross section of pipe fittings and pipes to swell together with the frost heaving liquid, which is not easy to crack. It can prevent condensation water and less heat damage. The raw materials are poor thermal conductors, which can reduce the problem of condensation water Reduce heat loss.

四、很輕，安裝操作便捷，而且具備可焊性，使用期長，系統軟件在要求的應用標準下使用壽命達60年。

IV. it is light, easy to install and operate, and has weldability and long service life. The service life of the system software reaches 60 years under the required application standard.

五、PP風管關鍵歸類：按用途歸類一般有：清潔管理體系送到通風風管、家用中央空調通風管道、工業生產送排風系統通風管道、環境保護管理體系吸排煙管道、礦用抽放瓦斯管、礦用涂膠帶風筒等。

V. key classification of PP air duct: it is generally classified according to the purpose: the clean management system to the ventilation duct, the household central air conditioning ventilation duct, the industrial production air supply and exhaust system ventilation duct, the environmental protection management system smoke suction and exhaust duct, the mine gas drainage pipe, the mine tape coated air duct, etc.
