The diaphragm is an important component of lithium batteries. It can isolate the positive and negative electrodes, prevent short circuits and battery overheating, and ensure the safety and stability of the battery. The quality of the diaphragm directly affects the performance and life of the battery, so it is very important to improve the quality of diaphragm products.

The dry uniaxial stretching production line is a commonly used diaphragm production line, which manufactures diaphragms by uniaxial stretching. During the production process, the addition of a polymer melt filter can effectively remove impurities and particles, improve the purity and uniformity of the diaphragm, and thus improve the quality of the diaphragm.

The dry biaxial stretching production line is a new type of diaphragm production line, which manufactures diaphragms by biaxial stretching. During the production process, the addition of a polymer melt filter can effectively remove impurities and particles, and can also control the thickness and pore size of the diaphragm, thereby improving the quality and consistency of the diaphragm.

The wet biaxial stretching production line is a high-end diaphragm production line, which manufactures diaphragms by wet preparation and biaxial stretching. During the production process, the addition of a polymer melt filter can effectively remove impurities and particles, and can also control the pore size and thickness of the diaphragm, thereby improving the quality and stability of the diaphragm.

In short, installing a polymer melt filter is an important means to improve the quality of lithium battery separator products. Whether it is a dry uniaxial stretching production line, a dry biaxial stretching production line or a wet biaxial stretching production line, you can install a polymer melt filter to remove impurities and particles, improve the purity and uniformity of the separator, and thus improve the quality of the separator.
