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;
