Description
Technical field
The present invention relates to building material technical field, more specifically a kind of dust collecting high molecular nanometer Graphene loads
Fibre bundle and production method thereof.
Background technology
At present, use the mode of vitrified bond to prepare during major part brickmaking, but be as the increase of clay yield, clay
Resource is the deficientest, not only increases cost of winning, ecological environment also causes having a strong impact on simultaneously, therefore needs optimization badly and change
Enter existing brick-making method to change the status quo.
Use sodium hydroxide decomposing zircon sand, be China's main production of producing now basic zirconium chloride and zirconium dioxide.
China's basic zirconium chloride yearly productive capacity in 2007 has reached 150,000 t, occupies the first in the world.As functional material and structural material
The demand of zirconium dioxide is also continuously increased, and its production technology cost is relatively low, but shortcoming is that producing substantial amounts of garbage (often gives birth to
Produce 1t zirconium dioxide product and about discharge sig water 5m, acid white residue 1t).In recent years, along with production-scale expansion, produced
The process problem of the garbage produced in journey also becomes increasingly conspicuous.
The raising of national life level of expanding economy band, the trend that the purchase volume of private car the most linearly rises,
Automobile environment inside car becomes the problem that people become more concerned with.Polluter in private car mainly has Aerosol Pollution and volatility
Organic Pollution, investigation shows: total volatile organic compound concentration can raise and the increase of off-period and urgency along with temperature
Sharp increase adds.This is because be all bonded together by chemical adhesive between a lot of materials in automobile, temperature raises and close
The volatilization of harmful substance is accelerated in closed loop border next time.So, keep often ventilating and in automobile, putting into adsorbing material, such as activity
Charcoal or melt-blown material and the joint product of bulky grain activated carbon, adsorb harmful gas, purifies air in private car, but this
The product of sample often has certain life-span, needs often to change, in the case of there is no labelling or reminding, and the most easily quilt
Forget or neglect, it is impossible to the environment being effectively ensured in private car.For private car environment pollution situation, urgent need to develop
A kind of aerosol that can filter can eliminate again the dual durable filtering material of volatile organic matter.Composite filter material filters because of it
The advantages such as efficiency height, low, the length in service life of filtration resistance come into one's own all the more
Therefore, utilize the anti-haze of dust collecting high molecular nanometer to turn waste into wealth, protect the effective measures of environment, farmland saving, have good
Good social and economic benefits.
Summary of the invention
