Vanadium titanium tailings gelcasting method for silica gel mold with aluminum powder modified complete-information surface

Abstract

A vanadium titanium tailings gelcasting method for a silica gel mold with an aluminum powder modified complete-information surface is characterized by comprising the steps of adding aluminum powder insilica gel and stirring uniformly to prepare aluminum powder modified silica gel; adjusting the viscosity of the aluminum powder modified silica gel by using a silica gel diluent; adding a curing agent to the outside of the aluminum powder modified silica gel, uniformly stirring, and then uniformly coating the surface of a silica gel mold with the mixture; after curing, adding an initiator and acatalyst in vanadium titanium tailings gelcasting slurry, stirring uniformly, and then injecting the mixture into the silica gel mold; and after curing at a certain temperature, demolding, drying, fettling and then firing to obtain the final product. The electrochemical properties (or surface chemical potential properties) of the surface of the silica gel are changed by addition of the aluminum powder, C=C double bonds in organic monomer acrylamide molecules in the gelcasting slurry can be smoothly opened under the effect of ammonium persulfate as the initiator to carry out polymerization reaction, the aluminum powder is added to modify the surface of the silica gel mold, thus, the curing strength of the surface of a cured blank is completely equal to the curing strength of the surface ofa metal mold blank, and thus, the surface information of the blank is complete.

Description

technical field [0001] The invention relates to an aluminum powder-modified full-information surface silica gel mold vanadium-titanium tailing injection molding method, which belongs to the technical field of ceramic material preparation. Background technique [0002] With the continuous improvement of living standards, people's requirements for the beautification and original ecology of the home environment and social public environment continue to increase. However, every artist or artist needs to spend a lot of time, money and energy to create a work. It cannot satisfy people's pursuit of beauty, so there is an urgent need for a method that can reproduce the exquisite works of artists or artists in large quantities at low cost; [0003] Every exquisite work of art is expressed by full-information surfaces such as creative graphics and graphic surface textures, animal skin hairs, and surface bumps, so their shapes are extremely complex. The best way to solve the above pro...
