pps風管與同類管材的區別和***勢

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

pps風管和pp管都是比較***的防腐管材，但是pps風管的價格卻比pp管貴很多，很多人都有疑惑，根據價格比較來看，***家一定覺得選擇pp管是***劃算了，同樣無毒、無味，防腐蝕，pp管價格比pps風管更便宜呀。其實并不是***家理解的那樣，pp管和pps風管是兩種有著不一樣的應用環境的管材，而且準確的來說，pps風管的綜合性能要***于pp管，而且pps風管是不可回收利用的，相當于一次的產品，通過這一點就能解釋了pps風管的價格要比pp管貴的原因。

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.

其實另一個很重要的原因是，pp管和pps風管的化學耐性也有不同，簡單來說，pp管耐酸性腐蝕更***一些，pps風管耐堿性腐蝕更***一些，包括壓電性，介電性這樣的***殊性能是pp管沒有的，所有嚴格來說這兩種管道的應用環境也就被區分開了。pp管主要的應用***域在工業方面，輸送一些帶有化學成分這類的介質，比如說制藥廠，煉油廠，污水處理廠，化工廠等等。

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風管更多是應用在食品行業中，根據食品安全的重要性，在管材的選擇上來說，也是十分講究的，飲用水的輸送管道肯定是***pps風管的，pps風管安全級別是目前已知管材中較高，為了保證食品的安全，選擇比pp管更貴的pps風管就是理所應當的。當然，由于pps風管出色的性能，也被廣泛的應用在微電子行業，比如保護在有高溫和油環境的電子元器件，機械配件以及電阻電容器，熱電偶的***緣保護以及電線未端、接續、端了的保護、補強和***緣等等。總的來說，pp管具有很***的普及性，pps風管雖貴但是有很***的針對性。

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.

一種***的管道，不僅應具有******的經濟性，而且應具備接口穩定可靠、材料抗沖擊、抗開裂、耐老化、耐腐蝕等一系列***點，同傳統管材相比，pps風管具有以下一系列***點：

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 連接可靠：管道系統之間采用電熱熔的方式連接，接頭的強度高于管道本體強度。

(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低溫抗沖擊性***：低溫脆化溫度極低，可在-60-60℃溫度范圍內安全使用。冬季施工時，因材料抗沖擊性***，不會發生管子脆裂。

(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抗應力開裂性***：PVDF具有低的缺口敏感性、高的剪切強度和***異的抗刮痕能力，耐環境應力開裂性能也非常突出。

(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耐化學腐蝕性***：pps風管道可耐多種化學介質的腐蝕，土壤中存在的化學物質不會對管道造成任何降解作用。因此不會發生腐爛、生銹或電化學腐蝕現象;此外它也不會促進藻類、細菌或真菌生長。

(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，使用壽命長：含有2-2.5%的均勻分布的碳黑的管道能夠在室外露天存放或使用，不會因遭受紫外線輻射而損害。

(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風管道與鋼管的耐磨性對比試驗表明，HDPE管道的耐磨性為鋼管的4倍。在泥漿輸送***域，同鋼管相比，pps風管道具有更***的耐磨性，這意味著HDPE管道具有更長的使用壽命和更***的經濟性。

(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可撓性***：pps風管道的柔性使得它容易彎曲，工程上可通過改變管道走向的方式繞過障礙物，在許多場合，管道的柔性能夠減少管件用量并降低安裝費用。

(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潔凈管道具有光滑的內表面。光滑的表現和非粘附***性保證pps風管道具有較傳統管材更高的輸送能力，同時也降低了管路的壓力損失和輸水能耗。

(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搬運方便：pps風管道比混凝土管道、鍍鋅管和鋼管更輕，它容易搬運和安裝，更低的人力和設備需求，意味著工程的安裝費用的******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.
