Wood Pulp Cotton​Product Specifications

The wood pulp cotton rag has the characteristics of zero pressure, ventilation and heat dissipation, and maintaining a constant temperature. It can sense the temperature of the human body and shape, and can still maintain a good degree of temperature in a low temperature environment. It can absorb moisture such as moisture and sweat in the air; it feels very soft and skin-friendly, but it is also supportive, which can reduce the pressure between the scalp and keep the blood circulation smooth; it also has the characteristics of non-toxic, safe and anti-mite.
Specifications of wood pulp and cotton products: It can be customized according to customer needs. Sedimentation type polyurethane biological filler is a new type of biological filler modified and synthesized by polymer polyurethane material. The macropores in the packing are combined with the micropores, and the macropores maintain good contact conditions of gas, liquid and solid. Micropores are used to adsorb and fix microorganisms. The micropores contain hydrophilic active groups such as amino groups, carboxyl groups, and epoxy groups. The filler can quickly absorb water and swell to sink water. At the same time, microorganisms and biological enzymes can be quickly adsorbed and fixed on the filler. .

The density of the filler after immobilizing the microorganisms is greater than that of water, so that the filler settles rapidly in the water body, the microorganism load is large, the volume load is large, and the specific surface area is large. Due to its structural characteristics, the filler can mix and contact sewage, air and biofilm, and a large number of biological strains can quickly settle in the microbial carrier, maintaining good activity and void variability, and gas during operation. Driven by the three-dimensional flow of sewage, they collide with each other and are continuously cut into smaller bubbles by the PPC filler in a peristaltic state, which increases the utilization rate of oxygen and reduces the amount of aeration. Therefore, it has the characteristics of strong ability to cut bubbles, large space utilization rate, and no dead zone.
