AI Technical Summary

Technical Problem

Current methods for cleaning calender rollers in electrode material production are inefficient, leading to reduced productivity, increased downtime, and compromised product quality due to the need for cooling and the use of volatile solvents, which are not suitable for high temperatures, resulting in residual contamination and defects.

Method used

A method and apparatus that utilize a mixture of esters, polyvalent alcohols, and glycol ethers, applied via a carrier material, to clean calender rollers during the production process, ensuring the rollers are not cooled, and a device that automates the cleaning process, allowing continuous operation.

Benefits of technology

The method and apparatus enable efficient, continuous cleaning of calender rollers at high temperatures, reducing downtime and ensuring consistent product quality by removing contaminants without cooling, thus enhancing productivity and preventing defects.

Abstract

The invention relates to a method for cleaning surfaces for the production of electrode material in accumulators, in particular for cleaning calender rolls (2, 3) in the production of anode and / or cathode foils. According to the invention, it is particularly provided that a carrier material (13) is moistened with a mixture, pressed against a roll (2, 3), and that contamination is removed by relative movement of the carrier material (13) and the surface of the roll (2, 3), preferably from the surface of the roll (2, 3).
