产品介绍

 PPS过滤毡是我厂选用美国、日本等国生产的聚苯硫醚(PPS)纤维,按照其它耐高温过滤毡的生产工艺,生产加工的过滤材料,为耐高温过滤材料的主要品种之一。PPS针刺滤料在以下场合的应用中性能卓越。

    1、工作温度190℃,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。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。

注:PPS也称聚苯硫醚纤维,在世界范围内只有少数几家大型化学公司生产,日本东洋(TOYOBO)公司的注册商标为“普抗®”“PROCON,日本东丽(TORAY)公司的注册商标为特利通® TORCON,美国飞利浦(PHILIP)公司的注册商标为“莱顿”也称“莱通”或“赖登”。

PPS high temperature resistant

PPS filter felt is one kind of main high temperature resistant filter mediums. Our factory have selected the polyphenylene sulfide (pps) fiber from America and Japan and followed the other producing technology of high temperature resistant filter felt to produce it, which is the most suitable for the following occasions:

1.Favorable temperature resistance melting point 285,working temperature 190,

instantaneous operating temperature232,limited oxygen index 34~35;

2.Be suitable for the oxygen content below 15%;

3.Oxide containing sculpture in the fuel or flue gas, now it has been proved that it was the fiber of anti-acid, alkali, abrasion and chemicals;

4.Containing moisture in the flue gas;

5.under the condition of 190~232 operating modes.

PPS fiber has strong integrate retentively and internal chemical resistance, which keeps good filter efficiency in the harsh environment, and reaching longer using life. PPS filter felt is the ideal filter material for the pulsate dedusting precipitator in the coal fired boiler, waste incinerator, powder and coal dust collecting in the electric power plant.
