PPS high temperature filter bag is the choice of the United States, Japan and other countries to produce fibers of polyphenylene sulfide (PPS), and other high temperature resistant filter felt production process manufacturing, processing of filter material, one of the main varieties of high temperature filter material. Because the characteristics of the PPS fiber itself needlefelt made ​​therefrom having other needlefelt not have the performance:

固安飞越PPS高温除尘布袋的主要性能

1、良好耐水解性，即使在160℃，79%相对湿度下连续使用500h。

2、经烧毛轧光处理可达到易清灰的效果。Good hydrolysis resistance, even in the 160 ° C, a relative humidity of 79%, used continuously for 500h.

3、耐热性：具有285℃的高熔点，所以特别具有长期的耐热性，可在190℃的温度下连续使用，并具有极强的耐蒸热性；即使在160℃的高压蒸气里也能保持90%的强度。Heat resistance: 285 ℃ a high melting point, it is particularly with long-term heat resistance, can be under 190 ° C the temperature of continuous use, and having a strong resistance to steam heat; even at 160 ° C in a high pressure vapor can also bemaintain 90% of the intensity.

4、耐化学性：杰出的耐化学品性能与含氟纤维的耐化学品性能媲美，在200℃或不足200℃的温度时，它能对大多数的酸（除一些诸如浓硝酸之类的几种氧化剂之外）碱和有机溶剂保持稳定的耐化学品性能。Chemical resistance: outstanding chemical resistance and chemical resistance of the fluorine-containing fibers comparable to 200 ° C the temperature is 200 ° C or insufficient, it can be for most of the acid (except for some such as concentrated nitric acid or the like severaloutside of the oxidizer) an alkali and an organic solvent to maintain a stable chemical resistance.

5、机械特性：它在强度、延伸度和弹性方面与聚酯基本相同。Mechanical properties: strength, elongation, and elasticity, and a polyester substantially the same.

6、难燃性：它显示了极高的难燃性和自燃性（LOI极限氧指数34-35）。Flame resistance: it shows a high flame resistance and auto-ignition (LOI limiting oxygen index of 34-35).

7、耐辐射性：对λ射线、中性子线等的放射线的耐受性，比传统的尼龙、聚酯有大幅度的提高。Radiation resistance: λ-rays, in the temper line radiation tolerance, have significantly improved than conventional nylon, polyester
