Recently, researchers from the University of Tokyo in Japan reported in the latest issue of the US "Science" magazine that they have developed a high-strength hydrogel that will not swell or deform even in water. For the manufacture of artificial cartilage and artificial eyeballs.
A hydrogel is a jelly-like substance that contains a large amount of water between polymer gaps. It can be used to make soft contact lenses, paper diapers, etc., but it is limited in application due to deformation and fragility after being placed in water for a long time. .
The researchers added a special polymer to a high-strength hydrogel with a regular mesh structure to produce a highly transparent hydrogel that does not swell in water that reaches human body temperatures. 90%. This hydrogel is simple to produce and has excellent ductility. Even if it is soaked in water for a month, its shape and strength will not change.
In addition, the strength of this hydrogel is also very high. A weight of 600 kg per square centimeter will not be crushed, while human cartilage can only bear a weight of 200 kg per square centimeter.
According to the researchers, since this hydrogel can retain its initial shape and high strength in the human environment, it is expected to be used for the production of artificial cartilage and artificial intervertebral discs. When transplanting induced pluripotent stem cells (iPS cells) into the body, the hydrogel may be used as a "base material" to promote cell differentiation and tissue formation.
A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power.[1] The various members such as pulleys and gears are mounted on it.
Transmission shafts are used to transmit power between the source and the machine absorbing power
Spindles are crucial parts for your lawn mower cutting deck that work together with the pulleys and belts to perform clean and even mowing.
Our shaft/ axle/ spindle we made normally applied on the transmissions, lawn mowers, trucks, excavator and other vehicles, etc.
The materials we used are normally mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used.
Shafts are generally formed by not rolling and finished to size by cold drawing or turning and grinding.
Some of the spindles are applied forging castings to save costs.
Main of our customers are from USA, CANADA, AUSTRALIA, German and Chinese domestic market.
