Products Description
A kind of weight-bearing tissue engineering bone porous pure magnesium scaffold and scaffold human-like bone material surface coating, the scaffold is made of high-purity magnesium powder and pore-making agent by powder metallurgy of a cylinder or disc with a diameter and height and randomly distributes the main hole, the connecting hole and the blind hole, the main hole is interconnected with each other, the blind hole is closed, the total volume of all holes accounts for 35-55% of the volume of the outer contour of the stent, the blind hole accounts for 2-5% of all holes, and the diameter of the main hole and the blind hole is 200-500 μm, The diameter of the connecting pore is 50-100 μm. The formation of the surface coating (4) of the scaffold is to immerse the scaffold in a 37 °C thermostatic coating solution containing Na.

Products cooperation picture
1.A titanium sponge production system involves the field of non-ferrous metal smelting, comprises a pretreatment module, a production module and an impurity removal module, and the pretreatment module comprises the following steps: first, ilmenite is pretreated to make an oxide pellet, and then the oxidation pellet is chlorinated and reduced to make a titanium tetrachloride liquid. The impurities in the pure magnesium powder are removed by the screening machine and the magnetic separator to avoid the impurities left in the pulverised coal after the grinding beads are worn, and the titanium tetrachloride and high-purity magnesium powder in the first heating box and the second heating box are gasified through two regenerative heating furnaces to form titanium tetrachloride steam and magnesium steam, and at the same time, the hot flue gas discharged by the two regenerative heating furnaces is exchanged with the reactor to preheat the reactor to reduce the energy consumption required by the reactor. After that, the reactor is evacuated through a vacuum pump to avoid the reaction of trace elements in the air with titanium tetrachloride and magnesium, which is convenient for continuous production to increase production efficiency and increase the purity of titanium sponge.
