Formaldehyde coupling "adsorption enrichment-reactive curing" two technologies.
Purification principle:
Formaldehyde coupling "adsorption enrichment-reactive curing" two technologies.
1. Pore-making and enrichment technology: With imported materials as carriers, after grafting polymer materials, high-tech means are used to make holes for formaldehyde molecules, thus leaving holes with the same size as formaldehyde molecules. These holes have the function of enriching formaldehyde and can form a high-concentration formaldehyde atmosphere around them.
2. Reactive curing technology: When formaldehyde molecules enter the pores, the grafted polymer reactive functional groups react with formaldehyde molecules quickly to generate stable and harmless compounds, thus completely eliminating formaldehyde pollution.
3. The formaldehyde gas in the air diffuses to the surface of the formaldehyde treasure, and is immediately captured and chemically fixed on the surface of the formaldehyde treasure. Therefore, Formaldehyde Bao will not release formaldehyde after removing formaldehyde, which is safe, reliable and thorough. The removal rate of formaldehyde in 3 hours is as high as 99.99%.
How to use:
1. Remove the odor of furniture, take the product out of the packaging bag and put it directly into drawers, wardrobes and cabinets.
2. For the elimination of indoor formaldehyde, it is suggested to take the product out of the aluminum film package, put it on the surface of sofa or desk, or tie a string to hang it indoors.
3. It is suggested to put a package in an independent space. If the space is large or the smell of formaldehyde is strong, the quantity can be increased appropriately.
Recommended dose:
Because formaldehyde treasure absorbs a lot and only reacts with formaldehyde, the total dosage is small. However, in order to make the effect more obvious, it is suggested to put a bag in an independent space, such as a place with a large space or a strong smell of formaldehyde, but when the quantity is increased.
R&D background
The 7th18 Research Institute of China Shipbuilding Industry Corporation has been engaged in the research and development of life support and purification and protection systems in confined spaces for more than 40 years, and has accumulated a lot of experience and technology in the detection, purification and protection of harmful gases. In recent years, in response to the call of the country to "convert military technology to civilian use", we have developed a series of "Perry" air purification products, making military technology enter thousands of households and benefit the public.
The research and development of Formaldehyde Bao is also one of a series of technologies. Aiming at the urgent demand for formaldehyde purification technology with high efficiency, environmental protection and convenient use in the market at present, relying on powerful military technology, a kind of formaldehyde filter material for civil air purification has been developed. The formaldehyde absorption material takes the absorption resin material as the matrix and chemically coats the high molecular polymer. After a brand-new process, holes are specially made for formaldehyde molecules, which has a remarkable effect on curing and eliminating formaldehyde released by various fabrics and wooden furniture. It solves the problem of indoor air pollution caused by formaldehyde, and has the advantages of high efficiency, durability, safety and environmental protection, simple application and no secondary pollution. At present, two national invention patents have been declared.
Formaldehyde contained in interior decoration materials is a kind of protoplasm poison, which mainly comes from building materials, bricks, concrete, plates, stones, thermal insulation materials, coatings and adhesives, among which the adhesive of interior decoration materials is the main source of formaldehyde. Formaldehyde itself is not an adhesive, but only acts as a "catalyst" in glue. The adhesion degree of glue is often directly proportional to its formaldehyde content, so it is widely used, and the release period of formaldehyde in glue is as long as 15 years, which makes formaldehyde a long-standing invisible killer in indoor air.
Because of its large polarity and small molecular weight, formaldehyde can freely shuttle through the pores of many broad-spectrum filter materials, which makes the commonly used air purification technology almost helpless. The formaldehyde treasure I developed is a combination of "adsorption enrichment" and "reaction curing". Using imported materials as carriers, after grafting polymer materials, holes are made for formaldehyde molecules by technical means, thus leaving holes with the same size as formaldehyde molecules. These holes have the function of enriching formaldehyde and can form a high concentration of formaldehyde atmosphere in the holes. When formaldehyde enters the cavity, the reactive functional groups of the grafted polymer react rapidly with formaldehyde molecules to generate harmless compounds, thus completely eliminating formaldehyde pollution. The rapid elimination of formaldehyde under the condition of no power is realized.
At present, when the concentration of formaldehyde at the entrance exceeds the standard by 20 times, we evaluate the comprehensive performance of formaldehyde filter media through formaldehyde purification efficiency, service life and adsorption capacity. The results show that in the initial stage of purification, the purification efficiency of formaldehyde by filter media is above 99% and lasts for nearly 300 hours. According to the time when the outlet concentration of formaldehyde reached the standard, the adsorption capacity of formaldehyde was calculated to be 55mg/g, and the service life was as long as 3 years.
Comparison of experimental data between formaldehyde treasure and activated carbon
Experimental conditions of purification project:
Formaldehyde formaldehyde treasure material: 2.66g
Formaldehyde concentration:1.25ppm.
Gas flow: 2l/min12.8mg/g.
Activated carbon material: 8.06g.
Formaldehyde concentration: 1.22ppm
Gas flow: 2 liters/minute 0. 195 mg/g.
Conclusion: In terms of treatment capacity, formaldehyde treasure is 65 times that of activated carbon. In addition, formaldehyde treasure is chemically adsorbed, and the treatment speed is much higher than that of activated carbon.
The use effect of formaldehyde treasure:
In a closed container (1m3), a certain amount of formalin solution is sprayed first, and then sealed, so that the formaldehyde in it can be fully volatilized evenly. The pollution produced by our laboratory can reach 30 mg/m3, which means that the pollution exceeds the standard by more than 300 times. At this time, in the absence of active breathing (highly toxic), you can feel the strong stimulation of the corners of your eyes and nostrils, leading to tears and sore nose. Then quickly hang two small bags (50g// bag of formaldehyde treasure) in the air of the closed room, that is, start the use test of formaldehyde treasure. After 6-8 hours, the concentration can reach below the environmental protection standard (that is, below 0. 1 mg/m3). At this time, active breathing will no longer stimulate tears.
Harm of formaldehyde
Formaldehyde is recognized as the "top killer in home improvement" and a highly toxic carcinogen, ranking second in the control of highly toxic substances. Formaldehyde also has the function of genetic variation, and long-term exposure of pregnant women can easily lead to neonatal malformation. With strong irritation, it will stimulate conjunctiva and respiratory membrane, leading to tears, runny nose, fatigue, insomnia, listlessness, memory loss and unconsciousness; Dizziness, headache, nausea and chest tightness.
Environmental protection ≠ reaching the standard
People should decorate their new homes and offices and buy furniture, because artificial boards (such as plywood, core board, medium density fiberboard and particleboard) are widely used in decoration and furniture manufacturing. Laminate flooring and composite wood flooring, etc. ), and the production of wood-based panels requires a large number of adhesives made of highly toxic formaldehyde. Due to the long release period of formaldehyde in adhesives, which is generally as long as 15 years, formaldehyde has become the main pollutant in indoor air. Formaldehyde has been identified as a carcinogen and teratogenic substance by the World Health Organization, and it is one of the potential strong mutagens. Its impact on human health is mainly manifested in abnormal odor, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function.
