According to the feature that deformation resulted from water absorption and mildew appear mainly on the rabbet surface of ccf, this paper adopts rsst to spray a special waterproof sealant on rabbet surface of ccf, so that the sealant can get into fiberboard to certain extent by means of capillarity and penetration, blockage the holes between fibers and capillary, cut up passage of water and change the properties of soakage and sorption to water in capillarity and fiber. at the same time, solidified sealant can form a compact waterproof pellicle on rabbet surface so as to prevent water and humidity from fiber ' s expansion and mildewing
針對吸水變形、霉變主要發生在地板企口表面的特徵，採用企口表面全封閉法，在復合強化地板企口表面噴塗特殊的防水封閉劑，使其依靠毛細管作用及滲透作用進入板內一定深度，堵塞木纖維之間的空隙及毛細孔通道，截斷水分傳遞的渠道，並改變毛細孔壁及纖維的表面性質以不利於水的浸潤與吸附，同時其固化后能在企口表面形成一層緻密的憎水薄膜，防止水分、濕氣從企口侵入板內引起木纖維膨脹變形、發霉等現象。When use the fireproof bag to seal and plug the hole of cable, first treat and arrange the cable in the hole, then edge the fireproof bag into the gap between cables, cable and plugging material or floor plate, put it interlaced just as laying bricks or stones and fill it firm and tightness as possible
