pp风管是什么材质的
What is the material of PP air duct
如今许多人到开展室内装修的那时候，都是采用PP风管，许多人对Pp通风风管的规定很高,包含材料,价格等各个***域。尽管小小Pp风管很不值一提可是却在家居装修中具有了尤为重要的功效。***家很关注PP通风风管的材料,那麼如今销售市场上的Pp通风风管都选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?
管事实上是指选用聚丙稀这种材料制做而成的,关键运用于房屋建筑房间内热水管供货系统软件,相对性于别的材料的管件来讲,其具备十分非常***的***势:
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风管的关键材料是聚丙稀，这是由丙烯聚合物而制取的这种热塑性树脂。无毒性、无臭、无气味的奶白色高结晶体的高聚物，相对密度只能4. 95--"4. 91g/cm3，别的材料的净重都不如它轻。值得一提的是，它的有机化学可靠性非常***，除能被浓硫酸、浓硝酸腐蚀外，对其他各种各样化学药品都稳定，但低含量的脂肪烃、芳香烃和氯化烃等能使聚丙稀变软和溶胀，一起它的有机化学可靠性随晶粒***小的提升还逐步提高，因此聚丙稀合适制做各种各样化工管道和零配件，耐腐蚀实际效果******。
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风管材料的***性：
Properties of PP air duct material:
1、不生锈:PP风管闸阀可在挺***的溫度范围之内承担pH,范畴在1～13的高浓的酸和碱的浸蚀。

2、抗磨损、不积垢:PP风管闸阀及管材内腔匀称光洁,流动性摩擦阻力小而且不积垢。
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、减少震动和噪音:PP风管闸阀具备***质的隔音性***性,可明显降低由液體流动性造成的震动和噪音。
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风管原材料延展性***质促使管件和管材横截面可随之冻胀的液體一块儿澎涨而不容易胀裂。
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,热损害少:PP风管原材料为欠佳热电导体,可降低冷凝水问题并降低热损少。
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、安装操作:PP通风风管很轻,安装操作便捷,而且具备可焊性。
6. Installation and operation: PP ventilation duct is light, easy to install and operate, and has weldability.
一、PP风管就是说用以气体输送机和遍布的管路系统软件，通风风管可按横截面样子和材料归类，按横截面样子，通风风管可分成环形通风风管，矩形框通风风管，扁圆通风风管等多种，至少环形通风风管摩擦阻力小的高宽比规格***，制做繁杂，因此运用以矩形框通风风管主导。按材料，通风风管可分成金属材料通风风管，复合风管，高分子材料通风风管。至少金属材料通风风管就是说用各种各样金属复合材料制做的通风风管，常见的包含镀锌钢板和不锈钢板等。
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通风风管由各种各样无机物原材料复合型而成，按构成不一样分成多种多样，但多见轻质混凝土，多孔结构，传热系数***的原材料，不生锈，可在挺***的溫度范围之内承担pH，范畴在1~13的高浓的酸和碱的浸蚀，抗磨损、不积垢，以及管材内腔匀称光洁，流动性摩擦阻力小而且不容易积垢。
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、减少震动和噪音：PP风管具备很***的隔音性***性，可更显降低由液體流动性造成的震动和噪音，防寒裂，原材料延展性***质促使管件和管材横截面可随之冻胀的液體一块儿澎涨而不容易胀裂，防冷凝水，热损害少，原材料为欠佳热电导体，可降低冷凝水问题并降低热损少。
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、很轻，安装操作便捷，而且具备可焊性，使用期长，系统软件在要求的应用标准下使用寿命达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风管关键归类：按用途归类一般有：清洁管理体系送到通风风管、家用中央空调通风管道、工业生产送排风系统通风管道、环境保护管理体系吸排烟管道、矿用抽放瓦斯管、矿用涂胶带风筒等。
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.
