Description
Technical field
The present invention relates to technical field of waste water processing, and in particular to a kind of film and the method for preparing film.
Background technology
In recent years, because enterprise's production technology falls behind, managerial skills are relatively low and supplies consumption is high, cause the dirt of unit product
It is too high to contaminate thing discharge capacity；Urban population growth excessive velocities simultaneously, industry are concentrated, and municipal sewage system and sewage treatment facility
Development speed is extremely slow.These masters, odjective cause cause the water environment in China constantly deteriorating.Traditional pollutant
（COD、BOD）, water pollution caused by eutrophication composition and all kinds of toxic chemical substances all increasing year by year, China 90% at present
Urban waters above are seriously polluted, and nearly 50% key cities water source does not meet drinking water standard, and environmental pollution improvement has turned into
Modern society one of is faced with major issue urgently to be resolved hurrily.Therefore, efficient, environment-friendly pollutant is being sought always by enterprise
Treatment technology is threatened with response environment.For national economy high speed development while, enterprise on the premise of economic benefit is pursued, more
More to pay attention to environmental protection problem.The discharge of pollutant how to be reduced with environmental protection, enables economy sane and sustainable development
Exhibition, is many enterprises major issue urgently to be resolved hurrily.
The content of the invention
The invention aims to solve the above problems, there is provided a kind of film, irradiate lower generation photocatalysis using sunshine
Reaction, dirty Organic substance in water of degrading, reach the purpose for administering dye wastewater.
In order to reach foregoing invention purpose, the present invention uses following technical scheme：
A kind of film, including using polypropylene nonwoven film as carrier, it is dispersed on carrier to have nano cupric oxide.
A kind of method for preparing the film, including step：
S1, by thick cuprous oxide after sand mill crushes, be mixed into water formation cuprous oxide slurries；
S2, using spray drying process, above-mentioned cuprous oxide slurries are dried to powder
S3, by the polypropylene powder of high fusion index and cuprous oxide powder in super mixer, be sufficiently stirred, by double
Screw rod is granulated mode, polypropylene and cuprous oxide is sufficiently mixed in screw rod；
S4, setting extruder temperature, wind pressure, lapping speed；
S5, after polypropylene composite materials master batch is uniformly mixed with high fusion index polypropylene, stretched through Screw Extrusion, spinneret, wind
Afterwards, lapping is into nowoven membrane.
The preferable step S3 includes：S31, extrusion, tie rod cooling, pelletizing, obtain cuprous oxide content it is high poly- third
Alkene master batch.
Preferably, it is described by temperature setting range be 60 DEG C ~ 120 DEG C.
Preferably, described by wind pressure setting range is 0.5MPa ~ 1MPa.
Preferably, including cuprous oxide particle size is controlled, scope is 50nm ~ 100nm.
Preferably, it is 80nm to control cuprous oxide particle size.
Compared with prior art, beneficial effect is the present invention：
1. the present invention, with regard to the organic matter in the sewage that can degrade, has a wide range of application under sunshine irradiation, is not only applicable to dyestuff
Waste water, daily life sewer can be also applicable, and contribute to environmental protection cause；
2. using carrier of the polypropylene nonwoven film as photochemical catalyst, because polypropylene density ratio water is small, shallow can keep afloat
On, expose to sunlight, nano cuprous oxide absorbs sunshine, produces photocatalytic effect, effectively utilizes solar energy；
3. polypropylene nonwoven film is easily manufactured, the cost into cloth more woven than conventional fibre is low, is advantageous to product promotion.
The present invention is dispersed in nowoven membrane to receive by composite method using polypropylene nonwoven film as carrier
Rice cuprous oxide produces light-catalyzed reaction using sunshine irradiation is lower, dirty Organic substance in water of degrading, reaches and administers dye wastewater
Purpose.
Brief description of the drawings
Fig. 1 is the flow chart of the preparation method of the present invention.
Embodiment
Explanation is further described to technical scheme below by specific embodiment.
If without specified otherwise, the raw material employed in embodiments of the invention is raw material commonly used in the art, is implemented
Method employed in example, it is the conventional method of this area.
The invention aims to solve the above problems, there is provided a kind of film, irradiate lower generation photocatalysis using sunshine
Reaction, dirty Organic substance in water of degrading, reach the purpose for administering dye wastewater.
In order to reach foregoing invention purpose, the present invention uses following technical scheme：
A kind of film, including using polypropylene nonwoven film as carrier, it is dispersed on carrier to have nano cupric oxide.
A kind of method for preparing the film, including step：
S1, by thick cuprous oxide after sand mill crushes, be mixed into water formation cuprous oxide slurries；
S2, using spray drying process, above-mentioned cuprous oxide slurries are dried to powder；
S3, by the polypropylene powder of high fusion index and cuprous oxide powder in super mixer, be sufficiently stirred, by double
Screw rod is granulated mode, polypropylene and cuprous oxide is sufficiently mixed in screw rod；
S4, setting extruder temperature, wind pressure, lapping speed；
S5, after polypropylene composite materials master batch is uniformly mixed with high fusion index polypropylene, stretched through Screw Extrusion, spinneret, wind
Afterwards, lapping is into nowoven membrane.
The step S3 includes：S31, extrusion, tie rod cooling, pelletizing, it is female to obtain the high polypropylene of cuprous oxide content
Grain.
It is described by temperature setting range be 70 DEG C.Described by wind pressure setting range is 1MPa, can improve the drop of organic matter
Xie Liang.
The control of cuprous oxide particle size can greatly promote organic matter in 80nm sizes, the cuprous oxide particle size
Degradation speed.
Non-woven composite membrane is dispersed in waste water from dyestuff, under the irradiation of outdoor sunshine, tested by spectrophotometer
Content of organics changes in waste water from dyestuff, and the content of reduction is considered as organic matter decomposition amount, sets different cuprous oxide crystal formations, chi
The parameters such as very little, concentration, irradiation time, optical wavelength, can be to the production of the degradation rate and degradation amount of organic matter in waste water from dyestuff
Raw different effect.
