Description
Technical field
The present invention relates to a kind of except formaldehyde filter and preparation method thereof.
Background technology
Along with people are more and more higher to the pursuit of quality of the life, air quality to the living space has also had higher pursuit, all kinds of household electrical appliances that purify air are favored on market, but have nothing in common with each other because of the purification techniques of different brands, and people are difficult to judge the superiority of its function when facing commodity.For the standard household electrical appliances market, 2011, country puts into effect a series of specific (special) requirements for household electrical appliance, and wherein relevant with air cleaning have GB 21551.6-2010 " antibiotic, the degerming of family expenses and similar applications electrical equipment, the specific (special) requirements of purification function air-conditioner ", a GB 21551.3-2010 " antibiotic, the degerming of family expenses and similar applications electrical equipment, the specific (special) requirements of purification function air purifier ".The air-conditioning of publicity " purification " function, the decontamination index that the needs of air purifier reach have been done clear and definite regulation:
| Pollutant | Purification efficiency (η) |
| Formaldehyde/ammonia/benzene | ≥25% |
Purification efficiency: air-conditioning is the purification efficiency of air-conditioning at the pure air amount of removing pollutant and the ratio of air-conditioning nominal air delivery.
The pure air amount: characterize the parameter of air conditioning purge ability, provide the value of pure air to represent (being called for short CADR) with the unit interval, take every cubic metre per hour (m3/h) as unit.
For example, the pure air amount of the purifying formaldehyde efficient (%) of air-conditioning=removal formaldehyde/air-conditioning nominal air delivery * 100%
The appearance of above standard, for the performance of present air-conditioning, air purifier had strict antibiotic, purify requirement.For example before standard was put into effect, air conditioner filter had certain function except formaldehyde, and air-conditioning just can be stamped the sign of " purification air-conditioning "; After standard is put into effect, the State Bureau of Quality Supervision spot-check " purification " electrical equipment on the market, testing result shows that a plurality of brands " purification air-conditioning " all can't reach the requirement of GB, the functional circuit that has is that the filter of prestowage has certain function of removing formaldehyde, but the performance of functional circuit complete machine and GB require parameter to greatly differ from each other, even the functional circuit that has has no function of removing formaldehyde and can say.So after new GB is put into effect, need the new purification techniques of exploitation to make the purification function of complete machine satisfy the requirement of GB.
In addition, there is following problem in the formaldehyde catalyst that removes of prior art: 1. catalyst easily comes off; 2. the moisture in the absorbing air and cause hydraulic performance decline; 3. generally speaking, the poor effect of its adsoption catalysis formaldehyde.
