What are the common types of gas cabinet membrane materials?

There are many types of gas cabinet membrane materials, and the common types mainly include the following:

Ⅰ. Classification by material

1.PVC membrane material

It is the most common biogas gas cabinet membrane material on the market. It has good plasticity, acid and alkali resistance, corrosion resistance, oxidation resistance and other properties, and is smooth and durable.

2.TPU membrane material

A high-performance material with high strength, good cold resistance, strong wear resistance and other characteristics. Compared with PVC membrane material, it has the advantages of more durability and longer service life.

3.HDPE membrane material

It has the characteristics of high material hardness, strong wear resistance, low temperature resistance, acid and alkali corrosion resistance, and long service life, but it is usually used in the production and manufacturing of large gas cabinets.

4.PU membrane material

Good softness, strong pressure resistance, long service life, not easy to age, stable quality, easy to process, and relatively low production cost.

5.PVDF membrane material

It is a copolymer of vinylidene fluoride homopolymer or vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers. The service life can reach about 15 to 30 years. It is widely used in the outer membrane of double-membrane gas cabinets, mainly used to adjust pressure and protect the inner membrane.

Ⅱ. Classification by coating

1.Double-sided PVC coated membrane

It has flame retardant, UV resistance, anti-aging and other functions, and is resistant to the main components of biogas, suitable for various biogas storage environments.

2.Double-sided PVDF coated membrane

In addition to the advantages of PVC coated membrane, it also has higher durability and corrosion resistance, suitable for more severe environmental conditions.

Ⅲ. Classification by function

1.Anti-corrosion membrane

Specially designed to resist the erosion of corrosive gases such as biogas to ensure the long-term stable operation of the gas tank.

2.Self-cleaning membrane

The surface is specially treated to reduce the adhesion of dust and dirt, reduce maintenance costs, and keep the gas tank clean and beautiful.

3.Insulation membrane

It has good insulation performance, can reduce energy loss, and improve the energy efficiency of the gas tank.

Ⅳ. Classification by shape and size

The gas tank membrane can also be customized according to the shape and size of the gas tank to meet the needs of different customers. For example, the membrane of the double-membrane gas storage tank usually needs to be customized according to the diameter, height and other parameters of the gas tank.

There are many types of gas cabinet membrane materials, and the selection needs to be considered comprehensively according to the actual application scenario and needs. At the same time, it is also necessary to pay attention to choosing products from regular manufacturers and brands to ensure the performance and quality of the gas cabinet.
