Alcoa researches and develops aluminum alloy fuel tanks for trucks

Alcoa has developed an aluminum alloy Dura-Bright fuel tank, landing gear, and composite plates. The aluminum alloy Dura-Bright fuel tank is resistant to corrosion and does not require polishing on the surface, which can make the surface gloss last for many years. The new aluminum alloy landing gear can reduce the weight of a truck's trailer by 100 pounds, and can meet or exceed all load conditions. This aluminum alloy landing gear, also known as the fifth wheel, uses the Holland Group's own "lubrication-free" technology. Made of 6061 T6 wrought aluminum plate, it reduces the weight by 100 pounds compared with the representative steel processed fifth wheel.

Venous Cannula

Venous cannula is also a deep venous puncture catheter. The method is to select the appropriate puncture site and insert the needle under the skin, and insert the needle with negative pressure until the dark red blood is absorbed, indicating that the needle has entered the vein, and the guide wire is inserted. Withdraw the puncture needle to leave the guide wire in the blood vessel, and then insert the venous catheter that needs to be indwelled along the guide wire, then exit the guide wire, inject diluted heparin saline and fix the catheter, the deep venous catheterization is completed. The veins for puncture and catheterization are usually selected clinically, including the subclavian vein, internal jugular vein, and femoral vein. After the puncture catheter is indwelled, attention must be paid to the care of the puncture site to avoid infection with thrombus or catheter falling off.
