产品特性：

product features ：

l 过滤性能: 精度高，流量大，压差小，效率稳定，纳污量高，使用寿命长，滤材消耗和过滤能耗低。

l filtration performance: high precision, large flow, small pressure difference, stable efficiency, high dirt holding capacity, long service life, low filter material consumption and filtration energy consumption.

l 结构完整：纤维间熔融自粘合，层与层之间纤维熔融粘合，不分层或脱落，具有更好刚性和微孔稳定性。

l strong structure: the fibers are self-bonded between the fibers, and the fibers are melt-bonded between the layers, without layered or shedding, and have better rigidity and micropore stability.

l 安全性好:采用食品级聚丙烯为原料，通过美国(fda)食品药物管理局有关检测，不使用任何化学粘合剂。

l high safety: use food grade polypropylene as raw material, and pass the relevant inspection by the us food and drug administration (fda), without using any chemical adhesive.

l 抗化学稳定性:聚丙烯对酸、碱、有机溶剂、油类均具有良好的化学稳定性。

l chemical stability: the polypropylene has good chemical stability to acids, bases, organic solvents and oils.
