Fig. 1 is present invention manufacture structural schematic diagram；
The reference numerals are as follows:
1, gas access, 2, quartz ampoule, 3, high temperature furnace, 4, quartz boat, 5, gas vent, 6, annealed zone；
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
It is as shown in Figure 1 a kind of manufacturing device of efficient deodorizing porous zinc bloom nanometer cylinder of the invention, including quartz
Pipe 2 and gas access 1 and gas vent 5 positioned at 2 both ends of quartz ampoule, the quartz ampoule 2 are located in high temperature furnace 3, the quartz
The center of pipe 2 is provided with quartz boat 4, and zinc sulphide is loaded with inside the quartz boat 4, and the gas vent 5 is connected to by pipeline
To annealed zone 6.
The present invention also provides a kind of manufacturing methods of efficient deodorizing porous zinc bloom nanometer cylinder, for manufacturing porous receive
Rice zinc oxide.
Concrete operating principle:
This, which studies main content, is made using the method heating zinc sulfide nano grade attritive powder of simple heating sublimation method
Distillation, and via being passed through reducing gas hydrogen and neon mixed gas, in mixed gas, hydrogen accounting most bottom 0.1%, most
High by 0.4%, reduction reaction, nonmetallic substance can be combined with hydrogen at this time, leave pure zinc particles.After reaction, annealing process
In, then it is aided with oxygen neon mixed gas, wherein oxygen accounting is 0.1%~0.5%, and one-dimensional oxygen is grown into the rear end of reactant
Change zinc porous nano column material.
The actual mode of operation of the method is to be heated reactant zinc sulphide with high temperature furnace, is always heated to sublimation point,
The temperature of distillation is scheduled on 950 DEG C Celsius by us in this experiment so that our reactant zinc sulphide from solid state sublimation at gaseous state,
And using hydrogen and neon mixed gas as carrier gas, the gas of product is taken away by high-temperature region with certain rate, and arrive
Annealing region, the gas of object is changed into solid-state from gaseous state once again just because of the change of temperature, and deposits.This deposition meeting
In accordance with object the specific crystallographic axis direction of growth and grow into the shape of porous nano column, then generate zinc sulphide at high temperature
Nano-pillar.It is aided with oxygen neon mixed gas again, a small amount of oxygen can be reacted at high temperature with zinc sulfide nano column, and be vulcanized
Zinc is easily reacted with oxygen at high temperature, generates zinc oxide porous column as a result, so zinc sulfide nano column is further formed oxidation
Zinc nano-pillar, reaction equation are expressed as follows:
ZnS(s)→ZnS(g) (1)
ZnS(g)+H2(g)→Zn(s)+H2S(g) (2)
2Zn(s)+O2(g)→2ZnO(S) (3)
Due to hydrogen in reaction with for transition substance, therefore overall reaction can simplify are as follows:
ZnS(g)+3/2O2(g)→ZnO(s)+SO2(g)；
Specific workflow:
Step 1: taking zinc sulfide powder to be placed in quartz boat first, then quartz boat is placed in the heating zone in quartz ampoule.
Then first pure nitrogen gas.Purpose is to drive air in furnace away, and 200 DEG C~400 DEG C are heated in the case of gas nitrogen and maintains one
Hour, so that aqueous vapor and air in pipe is got the gate.
Step 2: it is passed through hydrogen and inert gas mixed gas, and in mixed gas, hydrogen accounting most bottom 0.5%, highest
It 4% mixing and then is again heated to 950 DEG C~1250 DEG C, heat preservation 12~for 24 hours r, time is maintained to determine that amount is cured by the total amount of zinc sulphide
Few, the time is shorter, and postorder nanometer column volume is smaller, but is unfavorable for volume production.Therefore preferably one gram of zinc sulphide about needs 12 hours
Heating time can be reacted completely.Zinc sulphide is reduced to hydrogen sulfide gas and pure zinc solid at high temperature.
Step 3: after waiting reaction completely, in the annealing process that cools down, since hydrogen sulfide gas is easy to volatilize, zinc solid gas
Can be condensed in the process as particle, in annealed zone, be passed through oxygen neon mixed gas, wherein oxygen accounting be 0.1%~
1%, the collecting region of annealing flat-temperature zone (Annealing zone) obtains the nanoporous column of white flocculence.
It is subsequent that we can be incited somebody to action zinc-oxide nano porous column and plastic cement PET PA6 PP PE etc. in a manner of high-temperature fusion
Tool zinc-oxide nano porous column and a polymer are respectively implanted in a plastic mother granules manufacturing equipment, are set by plastic mother granules manufacture
Back-up will not have zinc-oxide nano porous column and polymer processing, plastic mother granules manufacturing equipment are mixed, to complete a tool
The plastic mother granules of zinc-oxide nano porous column.The polymer can be plastic rubber material, such as PET (poly terephthalic acid second two
Ester), PA6 (polyamide (NYLON), PP (polypropylene), PE (polyethylene), ABS (acrylonitrile-butadiene-styrene copolymer),
(polyvinylidene fluoride, PS (polystyrene), PES (polyether sulfone), PVC (polyvinyl chloride), PAN are (poly- by PC (polycarbonate), PVDF
Acrylonitrile) etc. other plastic cement polymer.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
