Conclusion
The dispersible polymer powder distributed on the interface is dispersed to form the form has another important function, which increases the adhesion of the contact material, and this is particularly important for those difficult to adhere, such as very low water absorption or non-absorbent surfaces, smooth surface of concrete and cement materials like steel plates, homogenous bricks, and vitrified tile surfaces; organic material such as wood and plastic. Because the bonding of the inorganic adhesive to the material is achieved by the theory of mechanical embedding, that is the hydraulic slurry penetrates into the gaps of other materials, gradually solidifies, and finally the mortar is attached to the surface material like key embedded in the lock. For the above hard-to-adhesive surface, since it can not effectively penetrate into the inside of the material to form a good mechanical embedding, the mortar with only the inorganic adhesive is not effectively bonded, and the observation by election microscopy is also a good proof of this. The bonding mechanism of the polymer is different. The polymer is bonded to the surface of other materials by intermolecular force, and does not depend on the void ratio of the surface. This is more prominent in the case of the organic base. The observation of the electron microscope also proves the superiority of its force. At the same time, the dispersible polymer powder containing ethylene has a stronger adhesion to organic substrates, especially similar materials such as polyvinyl chloride and polystyrene( of course the rough surface and the increased contact surface will increase the adhesion), This is used in polymer modified dry mortar for polystyrene board. This is a good example of bonding and overlaying.
