Description
Technical field
The utility model relates to water purification filter technical fields, refer in particular to a kind of cylindricality graphene sterilizing filter element.
Background technique
Sterilization process is industry and the civilian essential important link of filtration art, for the killing bacterium reached
Effect often solves problems by the way of reducing aperture of filter material, can reach preferable bacteria-eliminating efficacy；But with
The raising of bacteria-eliminating efficacy, filter efficiency will also greatly reduce, in order to solve problems, often using increase filter material area
Mode solved, virtually increase filtering cost.Simultaneously as the multilayer of traditional filter material, itself does not have
Standby bacteria resistance function, breeds a large amount of bacterium, it is easy to cause secondary pollution in use.
Nucleopore membranes have cylindric or cone cell pass structure, and the big low height of micropore size is consistent, and 100% retention of energy is greater than
The particle in aperture；Thermal stability is good, and in -70 DEG C~160 DEG C temperature ranges, performance is unaffected, therefore heat can be repeated
Pressure disinfection is without rupturing and deforming；Since substrate itself has good chemistry and biological stability, adsorption surface area is small, water suction
Property is low, not by microbial attack, can work in humid conditions for a long time；The particle of its film surface retention easily passes through surface washing
It removes, therefore can repeatedly use with backwash；Nucleopore membranes itself are thin dielectric films, and there is no filter membranes itself to filtrate
Pollution, also falls off without particle, fiber etc., therefore will not pollute filtrate as other filter paper.Therefore, nucleopore membranes are fine at present
Single layer filter material, big quantity of fluid and gas can be filtered under extremely low pressure, secondary pollution will not be generated.
Graphene is the honeycomb two dimensional crystal formed after electron orbit hydridization by single layer of carbon atom, and thickness is only
0.335nm.With excellent mechanical property, electronic effect, heat-conductive characteristic, optical characteristics, biological chemical performance, redox
Performance etc..According to future library, transistor, flexible display screen, new energy battery, sea water desalination, storage will be widely used in
Hydrogen material, aerospace, composite material and the medical applications in antibiotic and sterilizing field, water process, river regulation, cultivation Water warfare,
Multiple application fields such as air cleaning.Graphene is sterilized using three kinds of modes: the first is universal blade cutting, grapheme material
Assemble the body image ten thousand sword set of blades that nanoscale intensively combines one by one, the microorganisms such as bacterium, virus are micron orders, before the latter's ratio
Big 1000 times of person or so, when the microorganisms such as the bacterium of travelling, virus encounter graphene, just as encountering one sharp knife
The microorganisms such as bacterium, virus are directly cut into multistage and cut to death by piece；Second is bacterium hungry to death, and graphene has very strong absorption
Performance, bacterium once enter in its aggregation, can closely wrap up bacterium as cloth, absorb bacterium less than battalion
Support die of starvation；The third is slowly to wither away, and since graphene is too small, bacterium can swallow graphene, just as people has eaten foreign matter meeting
Cause uncomfortable, bacterium is caused slowly to be withered away.Exactly because this physical sterilization method of graphene, bacterium will not be generated
Drug resistance.
