(PPS)聚苯硫醚耐腐蚀针刺过滤毡

PPS high temperature resistant needle-punched filter felt 

产品参数说明: 
  

   PPS纤维耐温高具有强度的完整保持性和内在的耐化学性,可以在恶劣的环境中保持良好的过滤性能,并达到理想的使用寿命。PPS纤维高温下抗氧化能力不好,不能在含氧量过高的情况下使用。PPS过滤毡是理想的高温过滤材料,价格比高温滤料美塔斯低,是美塔斯滤料的理想替代品。
 
   我厂进口日本东丽PPS纤维,生产的PPS针刺毡所有指标达到国际水平。针对PPS纤维优异的热塑性,我厂采用进口全自动热熔技术生产的PPS热熔袋,滤袋的底部、侧面及领环连接的方法,都以热熔方法焊接,避免了传统线缝滤袋由于针孔、材质不均匀所产生的旁漏问题,纤维脱落问题等都被此种全热熔焊接的滤袋解决。高精度无线缝滤袋采用数码同位多点焊接设备,确保每一点的焊接都保持最牢固和一致。
 
PPS 针刺毡特性
       1、工作温度170℃,短时工作温度232℃,熔点285℃,极限氧指数34~35。
  2、含氧量在15%或以下的场合均可适用。
  3、燃料中含硫或烟道气中含硫的氧化物,现已证明其是抗酸碱腐蚀、抗化学性很强的  纤维。
  4、烟道中含湿气的场合。
  5、在温度190℃~232℃工矿条件下,气布比高达5:1做线上清灰及气布比6:1作离      线清灰时,PPS滤袋具有优异的性能纪录。
 
   PPS纤维具有优异的热塑性,PPS滤袋可制作热熔袋,
   应用:
   PPS针刺毡是目前用于燃煤电厂锅炉脉冲清灰袋式除尘器选用的主要滤料品种之一。在过滤燃煤锅炉、垃圾焚烧炉、电厂粉煤灰的集尘处理等脉冲清灰式除尘器中,PPS过滤毡是理想的过滤材料,按照工况条件的不同要求, 我公司可对PPS针刺毡做各种功能性处理,如拒水防油、PTFE浸渍、涂层、覆膜等。

Specification: 
  

   PPS fiber can keep intensity completely and bear chemistry naturing inherently, keep good filtration performance among the abominable environment, reach ideal service life. In coal boiler, rubbish incinerator, power plant of fly ash filtering of pulse clear dust catcher, PPS filter felts are an ideal filtration material. PPS filter felt is one of the main filter material able to bear the high temperature according to processed of production technology and artificial material of other high-temperature filter felt.
 
PPS (Polyphenylene Sulfide) Fibers Features
 
1. Exceptional Stability for a Wide Range of Temperature and Frequency Variations
(working temperature 190℃, instantaneous operating temperature 230)
2. Be suitable for the oxygen content below 15;
3. Chemical Resistance to Acids, Alkalis and Organic Solvents
4. Containing moisture in the flue gas; Hydrolysis Resistance
5. Very stable in finished felt form with stability standards at 2 shrink or stretch.
6. Favorable temperature resistance melting point 285, limited oxygen index 34~35;
 
Disadvantages

- Fair resistance to oxidation under high temperature
When the oxygen in the smoke ( O2 content) over 10 and the operating temperature over 165, pps will be in decomposition.
 
Applications
PPS needle felt are suitable for a range of baghouse filtration applications that include:
•  Coal - Fired Boilers bag houses
•  Municipal Solid Waste Boilers and Waste incinerator
•  Calciners / Catalysts
•  Electric power plant
•  Electrolysis and other Specialty membranes
•  Waste to energy
•  Iron and non ferrous Metal Industry
