On the original lithium battery diaphragm, whether crafted through the dry or wet method, we blend aluminum oxide, binder, and deionized water into a meticulously stirred slurry. This mixture is elegantly applied to the substrate diaphragm using the advanced micro-gravure extrusion coating technique. It is then adorned with a single or dual layer of ceramic surface, typically ranging from 2 to 4μm in thickness. This innovative ceramic diaphragm fortifies the original film's surface strength, endowing the battery with remarkable high-temperature resistance, anti-puncture resilience, and excellent anti-short circuit performance.
Simultaneously, this enhancement maintains permeability, ensuring seamless lithium ion flow, thereby elevating safety standards. The gravure coating principle has emerged as the industry's mainstay due to its impressive production capacity, ease of operation, and cost-effective investment. Moreover, the ceramic gravure roller, recognized as the 'heart' of coating equipment, plays a pivotal role in determining coating quality and visual appeal. Thus, the craftsmanship of a superior ceramic gravure roller is crucial, directly influencing the exceptional quality of ceramic diaphragm products.

Twill Roll Selection Angle: Dive into the Versatility of Micro-Concave Twill Rolls. Each angle uniquely caters to different industrial applications. For instance, the 45° twill roll, a favorite in membrane coating for lithium batteries, stands out with its remarkable performance. It excels in paint release, erosion and wear resistance, and ensures uniform coating thickness across the surface, proving its superior industry value.
Our meticulous processing flow begins with base roll forming, encompassing the selection of the finest steel embryo, precise lathe forming, and comprehensive modulation treatment. This phase is completed with the chrome plating anti-rust treatment of the shaft head to ensure durability. The surface sandblasting treatment follows, enhancing the ceramic bonding force. We then apply the bottom layer and proceed to ceramic spraying, typically using chromium oxide mixed materials. The exact formulation can influence the surface hardness of the ceramic layer, tailoring it to your specific needs. Our process continues with multiple rounds of grinding and polishing, followed by expert laser engraving. After rigorous testing, the process culminates in sealing, ensuring each product meets our superior quality standards.
