This invention discloses a hot-press curing method and system for carbon fiber rigid felt, relating to the field of carbon fiber rigid felt preparation technology. Its main objective is to avoid the threat to safe production posed by mixed gases containing VOCs during the hot-press curing process of carbon fiber rigid felt, and to reduce the amount of exhaust gas emitted. The main technical solution of this invention is: a hot-press curing method for carbon fiber rigid felt, comprising the following steps: Step S1, sealing the hot press and purging it with inert gas; Step S2, performing the hot-press curing process under inert gas protection, recovering alcohol; Step S3, performing the hot-press curing process in a dust-free environment and explosion-proof atmosphere, recovering waste liquid; Step S4, releasing the seal of the hot press to obtain the carbon fiber hot-press cured felt.

The utility model discloses an anti-scalding sealing lampshade, and belongs to the technical field of lampshades. The anti-scalding sealed lampshade comprises an outer shell, an inner shell capable of sliding up and down in the vertical direction of an inner cavity of the outer shell, and a bottom cover movably arranged at the bottom of the outer shell. According to the anti-scalding sealed lampshade, under the condition that an internal lighting device needs lighting, a user holds a holding cover and pulls the holding cover upwards, the light-transmitting lampshade is supported by a supporting part to move upwards to a proper position, a limiting clamping point is connected with the edge of the top of the outer shell in a clamped mode, and a ventilation channel is formed between the top cover and the holding cover; the oxygen demand during combustion illumination of the internal illumination device is guaranteed, positioning installation is rapidly completed by pulling the inner shell, use is more convenient, when not in use, the light-transmitting lampshade is contained in an inner cavity of the outer shell, large space is not occupied, the use effect is good, the top cover is of a double-layer heat insulation design, and under long-time use, the light-transmitting lampshade can be stored in the inner cavity of the outer shell. And a hand cannot be scalded when being touched.
