Description
Technical field
The invention belongs to environment-friendly materials, particularly relate to a kind of energy except ammonia and the material for air purification except second hand smoking and its preparation
Method.
Background technology
Air quality is healthy closely bound up with the mankind, according to statistics the time of people 80% live indoors, people
69% disease it is relevant with room air pollution.Environmental Protection in America general administration（EPA）A report point out that haze, fitment material for family are dirty
Under the comprehensive functions such as dye, second hand smoking, microbial bacterial, virus, kitchen fume, the degree of room air pollution is than outdoor air
It is serious 2-5 times, it is even up to 100 times under special circumstances.And the investigation that the World Bank does for 2013 shows, China is every
Year, excess outpatient service number was up to 220,000 person-times, excess urgency because the caused excess death toll of room air pollution institute is up to 11.1 ten thousand people
Number is examined up to 4,300,000 person-times.Therefore, how to improve IAQ (indoor air quality), eliminate room air pollution into people in the urgent need to
The problem of solution.
At present, the method for the treatment of indoor air pollution mainly has adsorption technology, electrostatic technique, photocatalysis technology, catalysis oxygen
Change technology, water film filtering technology and biological enzyme technology etc., are active carbon adsorptions wherein most commonly used, indoor pollutant
Most study is formaldehyde.It is relatively fewer for the research of ammonia and second hand smoking, and the also product of rare this class.Room air
In ammonia from construction material additive and brightening agent etc., it can be released slowly in room air, the breathing to human body
There are stimulation and corrosiveness, weaken resistance of the human body to disease, ultimately result in the symptoms such as respiratory tract disease.The harm of second hand smoking
No less than any other indoor air pollutants, huge injury can be caused to anemia of pregnant woman and child, particularly indoors under environment
Second hand smoking it is more difficult disperse, the harm to smoker itself and surrounding people is more serious, especially in closed office, chess and card
The places such as room, smoking room, toilet become apparent from.Therefore, research can quickly remove the product of ammonia and second hand smoking in room air
Product are significant.
Harmful gass are inhaled using porous material such as activated carbon, molecular sieve, aluminium oxide, zeolite, NACF etc.
Attached removal is most convenient and effectively, but will be failed after this porous material absorption saturation, and to a certain extent can
Again the harmful substance for having adsorbed is discharged, secondary pollution is caused.Generally need to be modified porous adsorbing material, such as load is urged
Agent or addition chemical reagent, with meet it is actually used in demand.Second hand smoking contain nicotine, tar, nicotine, alkaloid,
The multiple harmful substances such as amine, nitrile, alcohols, phenols, alkane, aldehydes, heterocyclic compound, nitrogen oxides, it is difficult to nuisance
Matter is all removed, and also the more difficult method for depending merely on absorption is removed.
Patent CN104368307A discloses a kind of ammonia special active carbon for adsorbing, first enters every trade leaching to activated carbon with mineral acid
Bubble process, in 110-130 after washingoIt is dried under C 24 hours, then impregnates the chlorination saline solution of 1-20% 24 hours, last 105-
130oC is dried 24 hours.Although this product process is simple, production time length, efficiency are low, and have used substantial amounts of nothing
Machine acid, can remain on the activated carbon, be likely to result in using rear discarding potentially hazardous.
Patent CN105214436A discloses a kind of material for air purification of reduction smog, and it adopts nonmetallic ore to adsorb
Agent, activated carbon, anion powder, kieselguhr, zeolite, pore creating material and binding agent etc. are raw material, grind to form fine powder, are led to after then mixing
Cross extrusion molding or pressing mold molding.Patent CN105152680A discloses one kind with epoxy resin, zirconium oxide, activated carbon, anion
The material for air purification that powder, shitosan, kieselguhr, pore creating material, binding agent, tourmaline etc. are prepared for raw material, with sterilization, except different
Taste, except functions such as second hand smokings.Patent CN102302876A disclose it is a kind of can purify air and the filtering material except second hand smoking,
By being coated with base fabric by the slurry of anion powder, nonmetallic ore adsorbing material, rare earth breeze, emulsion and nano silicon
Material, then dries and is obtained.We it is seen that, this kind of product has all used anion powder, for anion releasing, plays purification
The purpose of air.However, anion powder, i.e. tourmaline powder, tourmaline mainly picks up from solitary stone ore, containing big in its main component
The radiothorium element of amount and other a small amount of radioelement, should not use in the place of people Jing often activities, and this
The actual effect of product is extremely limited.
