Do You Know How The Foam Sponge Absorbs Water
Do you know how the water absorption principle of Foam Sponge is:
Foam Sponge is a kind of polyurethane foam material, with very good cache, seismic grade, heat insulation, waterproof, chemical corrosion resistance and other advantages, and no toxicity, odorless, moisture absorption and other characteristics. The structure is delicate, the surface is moist, the touch is soft and it is quite malleable. It has the function of earthquake resistance, waterproof, ground anti-slip and anti-wear. The sponge can reasonably block the impact and anti-vibration of the goods in the whole process of transportation, without the malleability of polluting organic chemistry and transformation.
So why can packaging sponge absorb moisture?
In fact, it is due to Foam Sponge hundreds of thousands of small porosity, and in view of the sponge, water infiltrating liquid, when the sponge in water, because water infiltration sponge, small round hole in the liquid are angled down concave shape, similar liquid surface tension bridle eraser membrane, if the liquid level is bent, it will change the trend of development.
Therefore, the concave liquid exerts a tensile force against the liquid below, and the convex liquid exerts a working pressure against the liquid below. The surface of the infiltrating liquid in the capillary is concave, and it releases a tensile force on the liquid below, making the liquid rise along the wall thickness. When the upward tensile force is the same as the force on the liquid column in the tube, the liquid in the tube stops rising, resulting in diffusion. So the water fills the space between the sponges.
In addition, the Foam Sponge have cache for an instant impact force ductility and strength, and its administrative levels feeling and visual effects for the soft be applied many commodities, such as naked drill box line, precision machinery and equipment in line, and the electronic equipment such as scope of many widely used, because the sponge can be cut and different production and processing is also won the customer's favorite; And has more than 100 kinds for customers to choose, such as: silencer cotton, slow elastic cotton, elastic cotton, fire safety cotton, carrying electrostatic induction cotton, conductive cotton, etc
