The present invention relates to an electrode drying apparatus and an electrode drying method, and the electrode drying apparatus includes: an oven configured to provide a space in which the electrode is dried and to include a hot air nozzle or an infrared heater; a color coordinate measuring unit configured to be positioned at an outlet of the oven and measure a color coordinate value of an electrode active material layer with respect to the dried electrode; and a controller configured to analyze a drying result of the electrode from the color coordinate value, determine whether the electrode is defective in drying, and control a drying condition of the electrode.

Electrode drying device and electrode drying method

The present application relates to a method for determining process conditions to remove volatile organic compounds from a polymer product through blowing. According to the method of the present application, time and energy can be saved.

Method for determining process conditions to remove volatile organic compounds from polymer

The present invention relates to a method for early detection of carbonization during the drying of an organic material. The method of the present invention measures temperature variation per unit time of exhaust gas containing water (HO), carbon monoxide (CO), or carbon dioxide (CO), which are to be generated by the pyrolysis of an organic material, and the concentration of carbon monoxide/carbon dioxide of the exhaust gas, so as to determine the occurrence of carbonization therethrough, thereby enabling early detection of carbonization within a dryer.

Method for early detection of carbonization during drying of organic material

A method for controlling a residual monomer content of a polymer, wherein when a hot-air temperature and a hot-air velocity are maintained, the controlling method can predict the content of the residual monomer by controlling a hot-air mass ratio without influence of other external factors.

Residual monomer content controlling method of polymer
