规格参数

NEPEM®全氟复合离子膜N-41PTFE系列是科润公司采用钢带流延法生产的复合全氟磺酸H型全氟离子膜产品。全氟离子膜在各种电解槽和电池中作为分隔阴阳极的固态电解质,NEPEM®膜具有阳离子单向通过的属性,由于采用高强度聚四氟乙烯网布作为支撑层,配合最为合适的分子量及离子交换容量的全氟磺酸树脂,NEPEM®-41系列复合全氟离子膜具有超强耐化学性和耐久性的特点。广泛用于:氯碱工业、电解水制氢、二氧化氯发生器、氨基酸精制、金盐制备、蚀刻液回收铜、电镀等领域。

包装:

尺寸:    
a.片材:
宽:   0.20 m (最小) 至 1.2 m (最大)
长度:0.20 m (最小) 至 1.2 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。

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。

NEPEM® N-417PTFE, N-410PTFE

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.
