Description
Technical field
The present invention relates to material for air purification technical fields, more particularly, to a kind of nano molecular charcoal.
Background technology
Air purification refers to removing haze for indoor various environmental problems offer sterilizings, depositing dust, dispelling harmful finishing
Residual and the total solution such as peculiar smell, raising makes the life better, office conditions, promotes physically and mentally healthy, indoor environmental pollution object
Include mainly radgas, mould, particulate matter, finishing residual, secondhand smoke etc. with pollution source, people need to suck sky when breathing
Gas, oxygen is ingested in alveolar, is then discharged out containing high concentration carbon dioxide and some other toxic, pernicious gas.Research
It was found that people's lung, which can be discharged more than 20, plants noxious material, wherein more than 10 kinds contain volatile poison, therefore, people crowded, air not
It in the room of circulation, often comes over dizzy, have difficulty in breathing, uncomfortable in chest, cold perspiration, nausea etc., symptom occurs in severe patient.In addition, suffering from
Pathogen can be broadcast to other people by the patient of respiratory infectious disease by expiratory air, sneeze, cough, phlegm and nasal mucus etc..
Tobacco will produce nicotine, tar, hydrocyanic acid etc. in burning.Nicotine can excitor nerve, vasoconstriction, rise
Hypertension and reduction tissue blood supply can improve zmount of oxygen consumption by increasing heart rate, and continuous sucking nicotine can excessively make one
It dies.Tar contains a variety of organic compounds, wherein containing substances such as micro BaP, benzene anthracenes, BaP has stronger carcinogenic
Effect.The data that the World Health Organization announces shows the lung cancer death of 65 years old or less male 90/100,75/100 chronic branch gas
The death of Guan Yan and pulmonary emphysema is due to caused by smoking, with being done step-by-step for fairly comfortable life, quality of the people to home environment
It also has higher requirement, finishing has become fashion at home, however people often ignore the living environment by finishing to strong
The influence of health and safety.
In recent years, the room air pollution situation caused by finishing problem was more and more common, and in these finishing pollutions,
Formaldehyde pollution, benzene homologues pollution etc. is very big to the health hazard of human body, causes the attention of all circles' understanding.Currently on the market
Air purifying preparation is mainly based on activated carbon and photocatalyst spray, and activated carbon is administered pernicious gas and is not thorough, because of adsorption saturation
Later, it is particularly easy to the case where pernicious gas overflows, sky is caused to go secondary pollution again occur, photocatalyst spray is of high cost, and
And photocatalyst is that spray is aerial, can only solve the pernicious gases such as the formaldehyde for being discharged into air for the moment, can not solve Interior Space
Gas pollutant acquisition time is up to the fundamental issue of 3-15, therefore, it is also desirable to novel material for air purification be developed, to avoid
It is insufficient existing for current material.
