The scientific name of nano sponge is melamine foam, melamine sponge, also known as high-tech foam, a clean, magic sponge, magic sponge, melamine sponge, is a new type of foam with high pore rate three-dimensional mesh structure. Its unique chemical structure and three-dimensional network crosslinking system make it have unique chemical and physical stability, in the weak acid and weak base environment will not aging, decomposition, no residual free formaldehyde, its hygiene can meet the requirements of food hygiene, with good secondary processing ability.
Sponge magic wipe using physical decontamination mechanism, relying on the nano-level capillary hole structure in the sponge, in the wipe process automatically adsorb stains on the surface of the object, like countless ultrafine vacuum cleaner in the work, only need water, completely does not rely on any chemical detergent to help degrade, so it is called magic. Explain capillarity: The surface of a liquid resembles a tensioning rubber film; if the surface is curved, it tends to flatten. So the concave exerts a pull on the liquid below, and the convex exerts a pressure on the liquid below. The surface of the infiltrated liquid in the capillary is concave, and it exerts a tension on the liquid below, making the liquid rise along the wall of the tube. When the upward tension is equal to the gravity force on the liquid column in the tube, the liquid in the tube stops rising and reaches equilibrium. The same analysis can also explain the phenomenon of non-infiltrating liquid descending in the capillary. Magic rub is the use of liquid surface to solid surface attraction effect, that is, to achieve physical decontamination.
