pps风管与同类管材的区别和***势

The difference and advantage between PPS air duct and the same kind of pipe

pps风管和pp管都是比较***的防腐管材，但是pps风管的价格却比pp管贵很多，很多人都有疑惑，根据价格比较来看，***家一定觉得选择pp管是***划算了，同样无毒、无味，防腐蚀，pp管价格比pps风管更便宜呀。其实并不是***家理解的那样，pp管和pps风管是两种有着不一样的应用环境的管材，而且准确的来说，pps风管的综合性能要***于pp管，而且pps风管是不可回收利用的，相当于一次的产品，通过这一点就能解释了pps风管的价格要比pp管贵的原因。

PPS air duct and PP pipe are better anticorrosive pipes, but the price of PPS air duct is much more expensive than PP pipe. Many people have doubts. According to the price comparison, we must think that it is the most cost-effective to choose PP pipe, which is also non-toxic, tasteless and corrosion-resistant. The price of PP pipe is cheaper than PPS air duct. In fact, it is not understood that PP pipe and PPS air pipe are two kinds of pipes with different application environments, and precisely speaking, the comprehensive performance of PPS air pipe is better than PP pipe, and PPS air pipe is not recyclable, which is equivalent to one-time products. Through this point, we can explain the reason why the price of PPS air pipe is more expensive than PP pipe.

其实另一个很重要的原因是，pp管和pps风管的化学耐性也有不同，简单来说，pp管耐酸性腐蚀更***一些，pps风管耐碱性腐蚀更***一些，包括压电性，介电性这样的***殊性能是pp管没有的，所有严格来说这两种管道的应用环境也就被区分开了。pp管主要的应用***域在工业方面，输送一些带有化学成分这类的介质，比如说制药厂，炼油厂，污水处理厂，化工厂等等。

In fact, another very important reason is that the chemical resistance of PP pipe and PPS air pipe is also different. In a word, the acid resistance of PP pipe is better, and the alkali resistance of PPS air pipe is better, including the piezoelectricity, dielectric and other special properties that PP pipe does not have. Strictly speaking, the application environment of these two pipes is also distinguished. PP pipe is mainly used in industry, conveying some medium with chemical composition, such as pharmaceutical plant, oil refinery, sewage treatment plant, chemical plant, etc.

而pps风管更多是应用在食品行业中，根据食品安全的重要性，在管材的选择上来说，也是十分讲究的，饮用水的输送管道肯定是***pps风管的，pps风管安全级别是目前已知管材中较高，为了保证食品的安全，选择比pp管更贵的pps风管就是理所应当的。当然，由于pps风管出色的性能，也被广泛的应用在微电子行业，比如保护在有高温和油环境的电子元器件，机械配件以及电阻电容器，热电偶的***缘保护以及电线未端、接续、端了的保护、补强和***缘等等。总的来说，pp管具有很***的普及性，pps风管虽贵但是有很***的针对性。

PPS air duct is more used in the food industry, according to the importance of food safety, in terms of the selection of pipes, it is also very particular, the transportation pipeline of drinking water is definitely the first choice of PPS air duct, the safety level of PPS air duct is currently known to be higher in pipes, in order to ensure the safety of food, it is reasonable to choose PPS air duct which is more expensive than PP pipe. Of course, due to the excellent performance of PPS air duct, it is also widely used in the microelectronics industry, such as the protection of electronic components, mechanical accessories and resistance capacitors in high temperature and oil environment, the insulation protection of thermocouples, and the protection, reinforcement and insulation of open end, connection, end, etc. Generally speaking, PP pipe has a good popularity, PPS pipe is expensive but has a good pertinence.

一种***的管道，不仅应具有******的经济性，而且应具备接口稳定可靠、材料抗冲击、抗开裂、耐老化、耐腐蚀等一系列***点，同传统管材相比，pps风管具有以下一系列***点：

A good pipe should not only be good economic, but also have a series of advantages such as reliable interface, simultaneous interpreting of materials, impact resistance, cracking resistance, aging resistance, corrosion resistance and so on. Compared with traditional pipes, a PPS wind pipe has the following advantages:

⑴ 连接可靠：管道系统之间采用电热熔的方式连接，接头的强度高于管道本体强度。

(1) reliable connection: the pipeline system is connected by electric melting, and the strength of the joint is higher than that of the pipeline body.

⑵低温抗冲击性***：低温脆化温度极低，可在-60-60℃温度范围内安全使用。冬季施工时，因材料抗冲击性***，不会发生管子脆裂。

(2) good impact resistance at low temperature: low temperature embrittlement temperature is very low, which can be safely used in the temperature range of - 60-60 ℃. During winter construction, due to the good impact resistance of the material, the pipe will not be brittle.

⑶抗应力开裂性***：PVDF具有低的缺口敏感性、高的剪切强度和***异的抗刮痕能力，耐环境应力开裂性能也非常突出。

(3) good stress cracking resistance: PVDF has low notch sensitivity, high shear strength and excellent scratch resistance, and also has outstanding environmental stress cracking resistance.

⑷耐化学腐蚀性***：pps风管道可耐多种化学介质的腐蚀，土壤中存在的化学物质不会对管道造成任何降解作用。因此不会发生腐烂、生锈或电化学腐蚀现象;此外它也不会促进藻类、细菌或真菌生长。

(4) good chemical resistance: PPS wind pipeline can withstand the corrosion of various chemical media, and the chemical substances in the soil will not cause any degradation to the pipeline. Therefore, it will not rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi.

⑸耐老化，使用寿命长：含有2-2.5%的均匀分布的碳黑的管道能够在室外露天存放或使用，不会因遭受紫外线辐射而损害。

(5) aging resistance and long service life: pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors without damage due to ultraviolet radiation.

⑹耐磨性***：pps风管道与钢管的耐磨性对比试验表明，HDPE管道的耐磨性为钢管的4倍。在泥浆输送***域，同钢管相比，pps风管道具有更***的耐磨性，这意味着HDPE管道具有更长的使用寿命和更***的经济性。

(6) good wear resistance: compared with steel pipe, the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipe, PPS air pipeline has better wear resistance, which means HDPE pipeline has longer service life and better economy.

⑺可挠性***：pps风管道的柔性使得它容易弯曲，工程上可通过改变管道走向的方式绕过障碍物，在许多场合，管道的柔性能够减少管件用量并降低安装费用。

(7) good flexibility: the flexibility of PPS air duct makes it easy to bend. In engineering, it can bypass obstacles by changing the direction of the duct. In many cases, the flexibility of the duct can reduce the consumption of pipe fittings and the installation cost.

⑻水流阻力小：PVDF洁净管道具有光滑的内表面。光滑的表现和非粘附***性保证pps风管道具有较传统管材更高的输送能力，同时也降低了管路的压力损失和输水能耗。

(8) small flow resistance: PVDF clean pipeline has smooth internal surface. Smooth performance and non adhesion characteristics ensure that PPS air pipeline has higher transportation capacity than the traditional pipe, but also reduce the pressure loss and water transmission energy consumption.

⑼搬运方便：pps风管道比混凝土管道、镀锌管和钢管更轻，它容易搬运和安装，更低的人力和设备需求，意味着工程的安装费用的******降低。

(9) convenient handling: PPS air duct is lighter than concrete pipe, galvanized pipe and steel pipe. It is easy to handle and install, with lower manpower and equipment requirements, which means the installation cost of the project is greatly reduced.
