鲜蛋冻裂的事故,一般发生在高、低温分层设置的冷库中,与其原因,自与冷库的布置形式有关。当蛋库在低温库上层时,密实性好,蒸汽渗透阻和导热系数都很大的22公分厚现浇钢筋混凝土无梁楼板设在低温一侧,渗入楼面隔热层内的水蒸汽难以从下表面散出,隔热层内易出现水蒸汽凝结区,使其效能降低。其次,底层鲜蛋与楼板之间空气流动不畅,冷空气积聚在楼板附 Frozen eggs accident, usually occurs in high and low temperature stratification of the cold storage, and its reason, since the layout of cold storage and form. When the egg bank is in the upper layer of low-temperature storage, the 22 cm thick cast-in-place concrete slab with good compactness, steam permeability resistance and thermal conductivity is located on the low temperature side, and the water vapor infiltrated into the floor insulating layer is difficult Out from the bottom surface, the insulating layer prone to steam condensation area, so that its effectiveness is reduced. Second, poor air flow between the ground floor eggs and the floor, cold air accumulation in the floor attached
