Abstract

The invention discloses a UV drying method for an optical film coating under the low oxygen environment. The UV drying method comprises the following step of introducing protective gas into an optical film drying space in a UV drying device to ensure the fact that the oxygen content of the interior of the optical film drying space is smaller than 400 PPM. The invention discloses a UV drying device. According to the UV drying method for the optical film coating under the low oxygen environment and the UV drying device, environmental friendliness, production increase and energy saving are realized.

Description

technical field [0001] The invention relates to the field of UV drying for optical film coating, in particular to a UV drying method and device for coating an optical film in a low-oxygen environment. Background technique [0002] Ordinary equipment for curing and drying optical films often produces harmful substances under aerobic conditions when the ink photoinitiator is used, which is not only not environmentally friendly, but also greatly affects the output. Moreover, the power of the UV lamp cannot be adjusted, so it is not energy-saving. Contents of the invention [0003] The purpose of the present invention is to provide a low-oxygen environment optical film coating UV drying method, which can realize environmental protection and increase production. [0004] The purpose of the present invention is to provide a UV drying device, which can realize environmental protection, increase production and save energy. [0005] In order to achieve the above object one, the p...
