Use the sizing agent of the present invention solid wooden floor board of mating formation, can solve existing defective:
When using rough ground that solid wooden floor board is installed, need to use steel nail that rough ground is fixed on the ground, it is larger that noise is installed; Use the sizing agent of the present invention solid wooden floor board of mating formation, as long as sizing agent is poured out, strike off with scraper plate and get final product, do not have noise.
Use rough ground that solid wooden floor board is installed, the reason that free tympany sound is arranged be fixing unreal due to, mainly be hair plates and keel, hair plates and flooring nail quantum count few or follow closely not firm due to.Use the sizing agent of the present invention solid wooden floor board of mating formation, the strong and even tight of bonding force of bonding force can not cause the hollowing sound between sizing agent and concrete floor and the solid wooden floor board.
Use rough ground that solid wooden floor board is installed, the major cause that stability is not good to cause arch camber, warpage or distortion is except floor too humidity or the drying, also have the distortion of rough ground timber, the hair plates piece is too little or seamless or use in due to the bubble wetland plate that leaks such as water pipe.Use the sizing agent of the present invention solid wooden floor board of mating formation, even solid wooden floor board makes moist, under the strong bonding force effect of sizing agent, solid wooden floor board is not yielding, arch camber also; Simultaneously, because sizing agent evenly is tiled between concrete floor and the solid wooden floor board, do not have the space, solid wooden floor board is stressed evenly, is difficult for causing distortion; In addition, sizing agent of the present invention is the elasticity sizing agent, and itself has elasticity, and when the too moist and drying in the solid wooden floor board part and predeformation, the elasticity of sizing agent can be disperseed the local stress that produces, and further reduces and is out of shape and the risk of warpage; Use this sizing agent also to get rid of arch camber, warpage or distortion that rough ground distortion itself causes; Also have a bit, sizing agent of the present invention has water-proof function, between laying and concrete floor and the solid wooden floor board, also plays the effect of moisture-proof barrier.
Use rough ground that solid wooden floor board is installed, can not be used for the ground heating system, solid wooden floor board is mated formation and must be used rough ground, destroys easily the ground heating system when rough ground is installed; Solid wooden floor board is heated yielding, not directly is paved on the ground heating system.Use the sizing agent of the present invention solid wooden floor board of mating formation, do not use rough ground, can not destroy the ground heating system; Use the sizing agent of the present invention solid wooden floor board of mating formation, as previously mentioned because the bonding force of sizing agent is strong, bonding force evenly, have elasticity, have water-proof function, resistance toheat, thereby can be used for the ground heating system.
For ease of understanding, below in conjunction with specific embodiment sizing agent of the present invention is described further.
