PTFE needle punched felt
产品参数说明:
PTFE针刺毡是采用PTFE(聚四氟乙烯纤维)经三维针刺而成的一种过滤材料。PTFE纤维为大分子线性结构,PTFE针刺毡因而具有极强的耐温、耐磨、耐腐、耐化学稳定性,广泛适用于钢铁、电力、垃圾焚烧等各种恶劣的烟气过滤环境。
产品性能:由100%纯PTFE制成;适用温度-210℃至265℃;耐酸碱、耐腐蚀、化学稳定性极强(0-14PH);高湿环境同样适用;不易老化;无污染;织物构成:PTFE短纤维(PTFE 卷曲纤维与其他纤维共混,即可降低成本,保持一定的不粘性。外观为纯白色。含量为100%聚四氟乙烯(PTFE)。加工时每平方厘米大于62针,使用抗静电剂,使用全钢设备,且必须使用接地装置。)+100%PTFE基布(使用500dtex长丝纤维(单丝)织造而成,织物为平纹组织。PTFE基布可以根据滤料的强力要求,设计不同的经纬密度。如:经向140根/10cm,纬向140根/10cm(140/㎡),基布的经纬向强力均可大于1000N),基于聚四氟乙烯原材料的化学稳定性,是所有滤料中耐化学性最强,稳定性最佳的产品。
1、持续工作温度250度以上,瞬间温度280度。
2、 完全不怕酸碱和氧化,几乎不可燃。
3、 唯一不会老化的纤维。
4、 满足最恶劣的工况,具有极长的使用寿命,通常使用寿命在4年以上。

Specification:
PTFE needle punched felt are produced from 100 PTFE fiber which has been punched in three-dimentional structure. They have excellent features such as excellent flexibility, molding capability, high tensile strength, creep resistance, high and low temperature resistance, corrosion resistance and anti-aging. 100 PTFE filter material can meet requirements in hostile environments of temperature fluctuating and acid & alkali in all PH range. The lifespan of PTFE filter material will be guaranteed for over 4 years as long as the temperature is controlled under the maximum operating temperature.
Product Feature:
have strong chemical stability (0-14 PH);
-
Can be used under high humidity environment;
-
Low shrinkage rate even if under high temperature,
-
Aging resistance;
