Ceramic Filter Plates are porous with a large area, fabricated with the preparation technology of inorganic membrane. It has the characteristics of large filter area, high strength and uniform bore. Its pore size can be adjusted in light of actual needs. With alumina as the base, the plate has fine acid alkali-resistance and can be washed in many ways including cyclic back-purge, acid cleaning and ultrasonic cleaning to avoid low filter efficiency over long-term use.
Features:
1. High skeletal density, high film strength & fine resistance against pressure and corrosion.
2. High open ratio, high production capacity, high filter fineness, low energy consumption in vacuum, fine material & complex whole without cementing.
3. Can be washed with organic solvents or under high temperature & high pressure. It has many generative methods with great generative effects to lengthen the service life greatly.
Dimensions: 1m²/12, 2m²/12, 3m³/12, 4m²/12, 5m²/12, 6m²/12, 8m²/12

Fluid filled porous materials are widely spread in nature and technology. Rocks, marine sediments, bones and sponges represent only a small portion of substances, which can be named porous materials. For many applications such as marine and geophysical or medical acoustics, clear understanding of the propagation of waves in such materials is of great interest. We present the basics of the theory based on the Lagrangian approach to the mechanics of penetrable porous materials. This theory is universal in sense that by construction it works for perturbation of arbitrary amplitude for isotropic, anisotropic, homogeneous or non-homogeneous materials. In frame of developed approach, the theory of propagation of acoustic (infinitely small-amplitude) waves naturally appears as approximation of the general theory in the small neighborhood of a stationary state of the material, which can itself be found in frame of static case of the theory. Also, we demonstrate critical importance of the waves of the second types for understanding of the propagation and attenuation of low frequency acoustic (seismic) waves in randomly non-homogeneous penetrable materials. At last, we discuss new alternative classifications of small amplitude wave modes based on classic representation of dispersion equations of propagating waves.

Sungmin Nam, a U-M assistant professor of mechanical engineering and Jihun Lee, a graduate student in mechanical engineering, have successfully strengthened hydrogels by using a combination of components: a complex carbohydrate, or alginate, derived from brown algae and infused with calcium, and a highly-absorbent polymer called polyacrylamide.
There are parts of the body that science has found particularly hard to replace or restore, whether it's because of the natural attributes they possess or their location inside us.
Take the cartilage in your knee—a substance that wears down through aging, repeated use and injury. Or consider the skin that covers your elbow. For burn victims, even skin grafted from other parts of the body won't ever feel or perform the same.
In both cases, science has yet to come up with a long term replacement that allows for similar flexibility and durability. But hydrogels, "toughened" by researchers at the University of Michigan, hold the promise of providing tools that can replace and supplement cartilage, skin, collagen or other materials in the body.
"Hydrogels are very good at mimicking the tissue environment, both mechanically and biochemically," said Sungmin Nam, a U-M assistant professor of mechanical engineering. "So we use them as engineering tools that can be placed safely in the body."
And once on, or in, the body, they're capable of providing a framework for cellular growth, delivering medicine and acting as a protective layer. These toughened hydrogels can be used to create soft robots and medical devices, or even replace surgical sutures.

Cotton socks：
Very hygroscopic, cotton fiber porous, high elasticity, warm to wear. Heat resistance, wear resistance, good hygiene, and natural materials do not stimulate the skin. feel comfortable, light, and breathable, the texture is soft. Even if you wear it all day, your feet will feel very comfortable.
Thin:
Suitable for summer, keep your feet breathable and comfortable, and not easy to sweat.
Gel：
Make the gel at the behind of the heel, to sure the socks would not easy to fall down, and wears more comfortably.
Hand linking：
Hand-linking seam eliminates the annoying bump that runs across the toes of most socks. The seams are not raised, smooth to the touch, You won't feel uncomfortable.
