New water treatment technology, water treatment chemicals water treatment chemicals appear on the solid adhesive bonding as a main reason for the adsorption theory, known as adsorption theory of bonding. Theory: The main source of adhesion molecules bonding system force with the sticky adhesive surface of the adhesive force and has some identical adsorption properties. Adhesive molecules and the adherend surface molecules action process has two processes: the first stage is a liquid adhesive to the Brownian motion of molecules by means of the surface diffusion of the adherend, the interface of the two polar groups or segments with each other close, in this process, the temperature, the contact pressure applying adhesive viscosity and lower Brownian motion are conducive to strengthening. The second stage is the adsorption force generation. When the adhesive and the adherend intermolecular distance is reached, the interface will have a mutual attraction between molecules, so that the distance between the molecules is further reduced to a maximum steady state. In order to meet the different wastewater systems (such as paper waste, wastewater, food processing wastewater, etc.) need dedicated and strong, for a certain class of chemical substances in research and development of varieties imperative. Multifunctional water treatment chemicals water treatment agent is an important aspect of the study, the emergence of these new water treatment technology, water treatment agent will explore the production and application of chemical treatment of industrial water development have a significant role in promoting.
