Coating machine knowledge handout ---
Lithium-ion power batteries are new high-energy batteries that have been successfully developed in the 20th century. In the 1970s, it became practical. Because of its high energy, high battery voltage, wide operating temperature range and long storage life, it has been widely used in military and civilian small appliances, such as mobile phones, portable computers, video cameras, cameras, etc., and partially replaces traditional batteries. Large-capacity lithium-ion batteries have been tested in electric vehicles and will become one of the main power sources for electric vehicles in the 21st century, and will be used in satellite, aerospace and energy storage.
With the development of microelectronics technology in the twentieth century, the number of miniaturized devices is increasing, and high requirements are placed on power supplies. Lithium-ion power batteries have entered the practical stage of large-scale production. However, the coater is very close in the cell process of the lithium ion power battery.
The process of the coating machine: the pole piece substrate placed on the unwinding device is pulled out by the roller, and after automatically correcting, enters the floating roller tension system, adjusts the unwinding tension and enters the coating head, and the pole piece slurry is coated. The system's setup program is applied. The coated wet film enters the oven and is dried by hot air. The dried pole piece is tensioned by the tension system, and the winding speed is controlled to synchronize with the coating speed. The pole piece is automatically corrected by the correcting system to keep the substrate in the The center position is neatly wound by the winding device.
BOPP film data --
BOPP is an abbreviation for "Biaxially Oriented Polypropylene", which is a biaxially oriented polypropylene film.
The BOPP film is produced by first forming a melt of high molecular polypropylene into a sheet or a thick film through a narrow machine head, and then simultaneously or stepping at a certain temperature and a set speed in a dedicated stretching machine. A film that is stretched in two perpendicular directions (longitudinal, transverse) and subjected to appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearl film, biaxially oriented polypropylene metallized film, matte film, and the like.
In order to obtain better comprehensive performance, it is usually produced by a multi-layer composite method in the production process. BOPP can be combined with a variety of different materials to meet specific application needs. For example, BOPP can be combined with LDPE (CPP), PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture resistance, transparency, high temperature, low temperature, retort resistance and oil resistance. Different composite membranes can be applied to oily foods and precious tastes. Food, dry food, impregnated food, various cooked foods, monosodium glutamate, pancakes, rice cakes, etc.
From usage points:
Matting film---BOPP+ matting powder, product packaging for matting effect
Pearlescent film---BOPP+ pearl powder, used for pearlescent effect packaging, also has other materials of pearlescent film.
