b.片材:
宽:  0.30 m (最小) 至 1 m (最大)
长度:0.30 m (最小) 至 1 m (最大)
说明:膜的供货尺寸都是基于干燥的膜产品,在23℃和50%相对湿度条件下。空气的湿度、温度均会影响其尺寸,需要我公司代为预处理的产品我们保证为正公差,且需预处理产品均为片材。

包装:

膜的包装,采用卷装,数量较小时无卷芯,数量较多时含卷芯。由于全氟离子膜不同温度湿度下尺寸会有变化,NEPEM®全氟离子膜均使用硬质保护膜打底保护,以便于MEA的喷涂及裁减尺寸的稳定性,外包装采用塑料桶或者硬质纸箱包装。
特殊尺寸和包装请联系销售人员。


回收及处理:
由于焚烧时本产品会挥发出有毒有害物质,可采用填埋方法处理。只有在焚烧炉能够清除氟化氢和其他酸性燃烧产物的情况下才能焚烧。对本产品的处置必须遵守当地的相关法律法规。
本公司提供全氟离子膜的废料有偿回收服务,详情请联系科润公司销售人员

 

Perfluorinated ion exchange membrane ( NEPEM® -11Series ) Description

NEPEM® PFSAmembranes are non-reinforced films based on PFSA polymer, a perfluorosulfonic acid/PTFE copolymer in the acid (H+ ) form. NEPEM PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells which require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable. Widely used: vanadium battery, liquid flow battery, fuel cell, electrolysis water, hydrogen production and other fields

Size

Roll Standard roll:0.61m*100m 0.80m*100m Custom size:0.2m、0.3m、0.4m width with random length。 (There is a 50 m 2 minimum order requirement for non-standard roll widths andlengths.) Once opened and exposed to the environment, the membrane will equilibrate to the ambient relative humidity, and change in dimensions accordingly. Membrane order dimensions are specified and measured at 23°C and 50% Relative Humidity. The products that require our company to pretreat are guaranteed to be positive tolerances, and the products required for pretreatment are all sheets.

Package: The packaging of the film is wrapped in a small volume and has no coil core. As the size of the perfluoro ion membrane varies at different temperature and humidity, the NEPEM perfluoroionic membrane is protected by the hard protective film to facilitate the spraying of MEA and the stability of the size reduction. The outer packaging is packed in plastic barrels or hard cartons. Please contact the salesperson for the special size and packing.

 capable of scrubbing out hydrogen fluoride and other acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable federal, state/provincial and local regulations. Our company provides full recovery service for waste materials of fluorine ion membrane. For details, please contact sales staff of run company.
