Description

Technical Field

[0001] The utility model belongs to the technical field of polarizer base film conductive rubber rollers and relates to a rubber roller with wear-resistant and heat-resistant properties. Background Art

[0002] Polarizer base film transfer rollers are key components in the polarizer production process. Polarizers are important optical components widely used in display technologies such as liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). The base film is a crucial component of polarizers, and the rollers play a crucial role in the production and transfer of the base film. Polarizer base film transfer rollers play a vital role in the manufacturing of LCD devices such as monitors, televisions, and mobile phones. If these rollers lack wear and heat resistance, a series of problems may arise, negatively impacting production efficiency and product quality.

[0003] If the rubber roller is not wear-resistant, its surface will quickly wear out, resulting in increased surface roughness. This not only affects the contact quality between the rubber roller and the base film, reducing transmission efficiency, but the rough surface may also scratch the base film, causing surface defects and affecting the optical performance of the polarizer. Furthermore, a worn rubber roller may lead to uneven transmission, causing uneven stress on the base film when heated, further exacerbating damage to the base film. Therefore, there is an urgent need for a rubber roller with wear and heat resistance to address these issues. Utility Model Content
