規格參數

NEPEM®全氟復合離子膜N-41PTFE系列是科潤公司采用鋼帶流延法生產的復合全氟磺酸H型全氟離子膜產品。全氟離子膜在各種電解槽和電池中作為分隔陰陽極的固態電解質,NEPEM®膜具有陽離子單向通過的屬性,由于采用高強度聚四氟乙烯網布作為支撐層,配合最為合適的分子量及離子交換容量的全氟磺酸樹脂,NEPEM®-41系列復合全氟離子膜具有超強耐化學性和耐久性的特點。廣泛用于:氯堿工業、電解水制氫、二氧化氯發生器、氨基酸精制、金鹽制備、蝕刻液回收銅、電鍍等領域。

包裝:

尺寸:    
a.片材:
寬:   0.20 m (最小) 至 1.2 m (最大)
長度:0.20 m (最小) 至 1.2 m (最大)
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。

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。

NEPEM® N-417PTFE, N-4110PTFE

MEMBRANES FOR electrolysis

Product Information

NEPEM® PFSA N-417PTFE and N-410PTFE membranes are widely used in chlor-alkali industries, electro-dialysis, recovery of copper from etching solutions, synthesis for gold potassium cyanide , chlorine dioxide, and electrochemical reaction for amino acid. The membrane performs as a conducting separator and solid electrolyte in a variety of electrochemical cells which require the membrane to selectively transport cations across the cell junction.

NEPEM® N-41PTFE series membrane are reinforced membranes based on chemically stable ® perfluorosulfonic acid (PFSA) copolymer. Incorporation of the PTFE mesh reinforcement improves the mechanical property of the composite membrane and allows the membrane to restrict its swelling. The membranes show significant improvements in features such as better resistance to chemical attack and longer operating durability under electrolysing cell conditions.

Order and Packaging Information

Membrane dimensions are based on dry product conditioned at 23 °C and 50% relative humidity(RH) before cutting. The moisture content of the membranes will have an influence on their dimensions changes, including in the length, width, and thickness directions.

The standard product specifications for membrane pieces include:

? Width: 0.20 m (Min.) To 1 .20 m (Max.)

? Length: 0.20 m (Min.) To 1.20 m (Max.)

The membrane for cut pieces will depend on the size and quantity of the customer’s order requirements. All the membranes were pretreated which can be used directly. All the flatted membranes are shipped on a roll. Flat membranes are directly wound into a small roll. The membranes are protected with a polyethylene wrap and inner packaging, then placed in shipping hard cartons. Membrane pieces can be cut to non standard sizes, and special packaging provided at additional cost. Please contact our sales staff for details and availability.

 Recommended Storage Conditions

Prior to opening the original shipping box, the membrane does not require environmentally controlled storage. Membrane should be kept sealed in its original packaging until needed. After opening the package, store the material in a temperature and humidity controlled environment(temperature 25.0±5.0°C and humidity 45±5.0%RH). Acclimatize the membrane to the manufacturing environment for at least 48 hours prior to use. Once opened and exposed to the environment, the membrane will equilibrate to the ambient relative humidity, and change in dimensions accordingly. Scrap Disposal Preferred disposal options are recycling and landfill. Incinerate only if incinerator is capable of scrubbing out hydrogen fluoride and other acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable national laws and regulations. The process of recycling waste Fluoropolymer Resins is extremely complicated as there are many parts to be recycled and many hazardous materials to remove. Therefore, we recommend that it is more appropriate for customers to hand over the waste film to us for recycling.
