Nonwoven Functional Membrane Material Is Expected To Become The Leader Of Membrane Market In 2018.

< p > Europe < a href= "http://www.91se91.com/news/index_c.asp" > nonwovens Association < /a > it is predicted that nonwoven functional material is expected to surpass structural membrane materials in 2018 and become the absolute leader in the market of membrane materials.

< p > functional biodegradable nonwovens Metabolix material is a harmless bacteria to human body. The amount of nonwovens needed by this method has also decreased, which can greatly reduce energy consumption.

< /p >

< p > a new functional biodegradable nonwoven film Metabolix is exhibited on the new product recommendation meeting held by the US Massachusetts company in January 2014.

The biofilm is made of raw materials which are harmless to human body. These bacteria are cultured in aseptic fermentor with plant sugar, and the necessary plant sugar is extracted directly from plants.

The technology leader of Massachusetts said that the extracted bacteria were made of special technology and made of bio film products through chemical bonded nonwovens.

At the same time, the number of nonwovens required by this method has also decreased, which can greatly reduce energy consumption.

The shape, size and porous membrane structure of < p > Mictron film will not change even at high temperature around 200 degrees, which can completely prevent the short circuit caused by diaphragm deformation and shrinkage.

The Dongli company of Dongli has developed a functional polyaramid thin film Mictron with good heat resistance and good dimensional stability for lithium (Li) ion charged battery with aramid resin as "a href=" http://www.91se91.com/news/index_c.asp "> /a >.

Aramid resin, which forms Mictron film, is formed by condensation of aromatic two carboxylic acid and aromatic two amine. The material is characterized by high elastic modulus. Therefore, the shape, size and porous membrane structure of Mictron film will not change even at 200 degree high temperature. It can completely prevent the short circuit caused by diaphragm deformation and shrinkage, thereby improving safety.

< p > Wendvg, technical consultant of Dongli company, pointed out that in the process of manufacturing non-woven films, the uniformity of porous films and the speed of film formation have the same relationship. If we want to improve the speed of film formation, even if phase separation is performed, it is difficult to form homogeneous porous film.

However, by adding phase separation control agent to prevent aramid resin condensation, Dongli company broke through the dominant factors of porous membrane formation, and then formed a fine and uniform porous membrane without adjusting the film speed.

< p > "ordinary PE film will partially melt and block the hole after the temperature rises, so as to prevent short circuit under abnormal conditions, which is what we often call the cut-off function."

Wendvg said, "but in the future, the application market of lithium-ion rechargeable batteries will be extended to the field of vehicle and fixed power supply. Due to the requirement of large capacity quantification and high output power, the working temperature of the diaphragm will also rise, and the cut-off function will not ensure enough safety.

That is to say, at higher temperatures, the PE films that are now in circulation on the market will melt all together, which may lead to serious accidents of electrode contact. However, there is no such problem for nonwoven membrane products.

In order to achieve mass production in 2015, the company will continue to improve the Mictron film in the future.

< p > Electdy thin films are made of needle punched nanomaterials with high capacitance and dielectric properties, making the nonwoven membrane materials enter the threshold of the electronics industry for the first time and may be used in pistors.

< /p >

< p > Germany Sandler has recently announced the use of needle punched nanomaterials to develop a capacitive dielectric high-performance thin film material Electdy, making the nonwoven membrane material enter the threshold of the electronics industry for the first time and will be used in pistors.

The material used in this film is barium carbonate, which is made of flash spinning nonwoven technology. It has high dielectric constant and smaller capsule particles. Experimental data show that the small capsule particles are compatible with the main polymer and can be uniformly distributed, so the film capacitance obtained is two times the area of the ordinary capacitance unit.

< p > Perry, head of the project, points out that nonwoven film technology is an inevitable trend in the electronics industry. The next application of Electdy thin film materials is the gate dielectric of thin film field effect pistors.
