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 针对吸水变形、霉变主要发生在地板企口表面的特征，采用企口表面全封闭法，在复合强化地板企口表面喷涂特殊的防水封闭剂，使其依靠毛细管作用及渗透作用进入板内一定深度，堵塞木纤维之间的空隙及毛细孔通道，截断水分传递的渠道，并改变毛细孔壁及纤维的表面性质以不利于水的浸润与吸附，同时其固化后能在企口表面形成一层致密的憎水薄膜，防止水分、湿气从企口侵入板内引起木纤维膨胀变形、发霉等现象。
So although there are better oiliness in peng ii , peng iii , peng iv gas pool and there are industrial off - take potentia after compressive fracture , this gas pool belongs to lower permeability , convention sand - density sand , little to middle throat - punctate pore , sealing elasticity gas drive , partly poor water drive , normal pressure , net gas , lithologic trap to nose - like structure - lithology compounding trap model 所以，虽然新都气田蓬莱镇组蓬二、蓬三、蓬四段有良好的含油气性，且经过测试均获得工业产能。但总体上该气藏隶属低渗常规砂岩?致密砂岩，小及中喉?细孔孔隙型，定容封闭弹性气驱，部分弱水驱，常压，干气，岩性圈闭及鼻状构造?岩性复合型圈闭气藏类型。
