2results about How to "Easy to stratify" patented technology

This disclosure relates to the technical field of gasoline production. One embodiment of this disclosure provides an ethanol gasoline blending device, which includes: a blending tank and a connecting flange. The connecting flange is disposed at the bottom of the blending tank. A feeding blending assembly is disposed inside the blending tank. The feeding blending assembly includes a fixing frame disposed at the top of the blending tank. A transmission port is opened at the top of the blending tank. A first feeding pipe is disposed inside the fixing frame. The first feeding pipe passes through the transmission port and is located inside the blending tank. A plurality of dispersion holes are opened around the outer surface of the first feeding pipe. A rotating tube is fitted outside the first feeding pipe. A plurality of elongated openings are vertically opened around the outer surface of the rotating tube. Through the above technical solution, the technical problems in the prior art are solved, such as the significant difference in density and viscosity between ethanol and gasoline, and the large influence of temperature on their miscibility, which easily leads to local stratification when directly mixed in the main tank, resulting in prolonged stirring time and difficulty in avoiding trace phase separation.

The application discloses an anti-impact and anti-scratching automobile hub cover and a preparation method thereof, and relates to the technical field of high polymer materials.The automobile hub cover comprises at least: 100 parts of nylon 6 resin; 5-15 parts of bismaleimide resin prepolymer; 10-15 parts of hydrogenated styrene-butadiene block copolymer grafted maleic anhydride; 10-20 parts of modified basalt fiber; 5-15 parts of modified polyarylate fiber; 0.2-0.5 parts of antioxidant; 0.3-0.8 parts of light stabilizer; 2-4 parts of color master batch; 0.3-0.8 parts of lubricant; the bismaleimide resin prepolymer is prepared by mixing 4,4'-diphenylmethane bismaleimide and 2,2'-diallyl bisphenol A; the modified basalt fiber is co-precipitated and modified by polydopamine, polyethyleneimine and octaamino cage-shaped polyhedral oligomeric silsesquioxane functionalized graphene oxide; and the modified polyarylate fiber is co-precipitated and modified by polydopamine and polyethyleneimine.The automobile hub cover prepared by the application has low moisture absorption, high impact resistance and excellent scratch resistance.
