說明:膜的供貨尺寸都是基于干燥的膜產品,在23℃和50%相對濕度條件下??諝獾臐穸?、溫度均會影響其尺寸,需要我公司代為預處理的產品我們保證為正公差,且需預處理產品均為片材。

包裝:

膜的包裝,采用卷裝,數量較小時無卷芯,數量較多時含卷芯。由于全氟離子膜不同溫度濕度下尺寸會有變化,NEPEM®全氟離子膜均使用硬質保護膜打底保護,以便于MEA的噴涂及裁減尺寸的穩定性,外包裝采用塑料桶或者硬質紙箱包裝。
特殊尺寸和包裝請聯系銷售人員。


回收及處理:
由于焚燒時本產品會揮發出有毒有害物質,可采用填埋方法處理。只有在焚燒爐能夠清除氟化氫和其他酸性燃燒產物的情況下才能焚燒。對本產品的處置必須遵守當地的相關法律法規。
本公司提供全氟離子膜的廢料有償回收服務,詳情請聯系科潤公司銷售人員

 

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.
