Hybrid cladding technology-based radiation protection improved multimedia podium

Abstract

The invention relates to a hybrid cladding technology-based radiation protection improved multimedia podium, belongs to the field of office furniture, and aims to solve the problem that the design defect in radiation protection is present in a widely used multimedia podium which is provided with a CRT display in colleges and universities and other similar mechanisms at present. In the podium structure, an air insulating baffle is arranged at a position between a picture tube and a key tray below the podium surface, and an anti-radiation coating is coated on the surface on one side, facing the picture tube, of the air insulating baffle. The material of the anti-radiation coating is a composition of a polyurethane adhesive and lead powder, the weight percentage of the lead powder in the anti-radiation coating is 10 to 90 percent, and the lead powder is preferably nano lead powder. Due to the structure, the radiation protection aiming at the side face and rear part of the picture tube is effectively enhanced, and related radiation hazard is suppressed. The hybrid cladding technology-based radiation protection improved multimedia podium contributes to improving the working environment of a podium user.

Description

technical field [0001] The invention relates to a multimedia lecture platform with improved radiation protection based on the hybrid coating technology, belonging to the field of A47B office furniture. Background technique [0002] Existing a kind of multi-media lecture platform that has been widely used in colleges and universities and other similar institutions has installed CRT monitor has design defect, and this will start from the structure of CRT monitor installed therebetween, in CRT monitor structure, in order to restrain The radiation damage to the user caused by the X-rays produced by the electron beam bombarded by the electron gun in the picture tube is generally considered to be due to the use of a large thickness of lead-containing glass on the screen of the CRT display facing the user. In this way, the radiation dose of X-rays to the front of the user's head and upper body is weakened or suppressed, and at the side and rear of the CRT display picture tube, beca...

AI Technical Summary

Problems solved by technology

[0005] CRT monitors are cathode ray tube monitors. Due to their solid structure and low price, for a long period of time, podiums equipped with CRT monitors will also be used in crowded and active classrooms such as college classrooms, middle school classrooms, and elementary school classrooms. The place is still widely used, and the general health damage to relevant practitioners caused by the above-mentioned design defects in the radiation protection of the podium has not stopped.
