Hydrophilic sedimentation type polyurethane biological filler is a new kind of biological filler modified and synthesized by polymer polyurethane material. The large and micro holes of the filler are combined, and the large holes maintain good contact conditions of gas, liquid and solid. Microporous for adsorption fixed microbe, microporous with amino, carboxyl, epoxy group, such as hydrophilic reactive group, the packing can rapidly absorbing water and expansion submerged at the same time will microorganisms and biological hydrophilic sponge with zero pressure, air cooling, constant temperature etc, can shape, to feel the temperature of the human body and in low temperature environment, still can maintain good degrees; At the same time, the open molecular structure of the material has strong permeability, so it can absorb moisture and sweat in the air; It feels very soft and skin-friendly, but with support, it can reduce the pressure between scalp and keep blood night circulation smooth. It also has the characteristics of non-toxic safety and mite prevention. The enzyme quickly adsorbed and fixed on the filler. The density of the packing after immobilized microorganisms is greater than that of water, which makes the packing settle rapidly in the water, and the microbial load is large, the volume load is large, and the specific surface area is large. Packing because of its structure characteristics, can make the water, air and biological membrane mixing exchange exposure, biological species can instantly enthronement in large quantities in the microbial carrier, keep good activity and space variability, and gas in the process of running in a three-dimensional flow of sewage, collide with each other and been in a creep state PPC packing is cut into smaller bubbles, The utilization rate of oxygen is increased and the aeration rate is reduced. Therefore, it has the characteristics of strong bubble cutting ability, large space volume utilization, no dead zone and so on.

Sponges have countless pores, and for sponges, water is a permeable liquid. How does a sponge become hydrophilic when it touches water? Hengfeng will explain the hydrophilic principle of sponge for you.
When a sponge hits water, the surface of the water is concave and the liquid surface resembles a tensioned rubber film. If the liquid level bends, it tends to flatten. Thus, the concave liquid exerts tension on the liquid below, and the liquid presses on the liquid below. The surface of the permeable liquid in the capillary is concave, which exerts a pull on the liquid below, causing it to rise along the tube wall. When the upward pull equals the gravity of the liquid column in the tube, the liquid in the tube stops rising. Capillarity is formed. Water is then allowed to fill the gap, making the sponge hydrophilic faster. |
