When the outer gypsum board contains the formaldehyde adsorbing material, harmful gases such as formaldehyde which are not degraded by the formaldehyde degradation material are adsorbed, and enter the cavity between the outer gypsum board and the heat insulating layer through the one-way breathing film, due to the cavity and the house The exhaust vents are in fluid communication, and harmful gases such as formaldehyde are discharged outside, so that the outer gypsum board can continuously adsorb harmful gases such as formaldehyde in the air.
本申请的具有空气净化功能隔墙系统中的紫外灯放出的热量可以被相变石膏板所储存，在夜间或室内温度低时放出能量，达到调节室内温度的目的。紫外灯设置在空腔的顶部，由于空腔顶部的龙骨上有一个开孔并且开孔的尺寸小于空腔的尺寸，使得含有甲醛的空气经过开孔时流动通道变窄，增加了停留时间，延长了反应时间，从而提高甲醛净化率。The heat emitted by the ultraviolet lamp in the air purification functional partition wall system of the present application can be stored by the phase change gypsum board, and the energy is released at night or when the indoor temperature is low, so as to adjust the indoor temperature. The UV lamp is disposed at the top of the cavity. Since the keel on the top of the cavity has an opening and the size of the opening is smaller than the size of the cavity, the flow channel of the formaldehyde-containing air is narrowed when the opening is opened, thereby increasing the residence time. The reaction time is prolonged, thereby increasing the formaldehyde purification rate.
