Description
Technical field
The present invention relates to material for air purification fields, and in particular to a kind of composite particles material for VOCs such as purifying formaldehydes
Material and preparation method thereof.
Background technique
2015, " with the carcinogenic substance inventory at position and cancer name class " that international cancer research institution (IARC) updates
In just clearly marked: have sufficient and strong evidence (sufficient evidence), formaldehyde can induce leukaemia.
Currently, formaldehyde is listed in 1 class carcinogenic substance together in the carcinogenic substance list of IARC with benzene, caffeine, alcohol, tobacco.
According to incompletely statistics, the whole world there are about the death of 7,000,000 populations is caused directly or indirectly by formaldehyde every year.Mesh
Before, the material of purifying formaldehyde is mainly based on active carbon in the market, but active carbon PARA FORMALDEHYDE PRILLS(91,95) only serves physisorption, absorption
It is easy to generate desorption effect when the extraneous factors such as temperature, relative humidity change after saturation, in turn results in the secondary dirt of formaldehyde
Dye.Simultaneously as the slow release of formaldehyde, release at least needs the 5-10 year completely, and the effective storage life of active carbon is non-
It is often short, formaldehyde pollution can not be solved the problems, such as from the root.Therefore, the net of a kind of sustainable absorption and fast decoupled formaldehyde is developed
Change material, has great importance for administering indoor pollution, improvement living environment, promoting quality of life.
Summary of the invention

Gas provides stratiform and needle-shaped surface and interface active layer；MnO in psilomelane2As catalyst, C can be substantially improved and decompose particle pair
The decomposition efficiency of formaldehyde；Tourmaline has super-active and then promotes formaldehyde point due to the releasable negative oxygen ion of spontaneous polarization properties
The quick separating of oxygroup chain in son, meanwhile, the negative oxygen ion of release, which can actively dissociate, promotes formaldehyde point to each corner in room
Formaldehyde removing efficiency is greatly improved in the decomposition of son, solves purifying indoor formaldehyde Dead Core Problems.
(3) C of the present invention decomposes particle, and potassium permanganate is carried on powder coal ash glass-microballons surface and duct table
Face, by the strong oxidizing property of potassium permanganate and the high surface of powder coal ash glass-microballons, significant increase potassium permanganate and formaldehyde
The contact probability of gas makes formaldehyde gas that oxidation reaction occur, resolves into carbon dioxide and water.Meanwhile potassium permanganate and formaldehyde
Reaction generates potassium manganate, and color gradually becomes brown or black from purple, has excellent colour developing experience effect, and family can be used
Intuitive decomposition and purification process of the sense organ to formaldehyde.
(4) composite particulate material of the present invention for VOCs such as purifying formaldehydes, by the way that A is adsorbed particle, B is activated
Particle and C decompose particle and are uniformly mixed in certain proportion, in use, A absorption particle first inhales the VOCs gas molecule such as formaldehyde
It is attached to particle surface and internal control surface, forms the adsorption layer for being rich in formaldehyde molecule, B activated particle is realized by releasing negative oxygen ion
Aldehyde effect is removed at a distance, the VOCs gas molecule such as formaldehyde for recycling load to have the C decomposition particle of high oxidative to be enriched with periphery
Oxygenolysis is carried out, physical absorption, long-range activation and chemical breakdown are organically combined, significant increase purifying formaldehyde effect
Rate realizes lasting, quick, efficient elimination formaldehyde harm.
