Abstract
A kind of method for removing indoor formaldehyde gas pollution, active carbon powder is mixed into acrylonitrile-vinylidene chloride stoste, it is fixed on polyacrylic and polyester fiber carrier by the method for spinning, general activated carbon can be solved while activated carbon adsorptive capacity is not damaged and is difficult fixed-type problem.
Description
Technical field
It is a kind of using the AN-VDC copolymer fibers of activated carbon are contained come the method for formaldehyde adsorption specifically the present invention relates to a kind of method for removing indoor formaldehyde gas pollution, belongs to field of Environment Protection.
Background technology
Recently as the improvement of people's living standards, increasingly pay attention to the attractive in appearance and comfortable of indoor decoration.But decoration also brings serious indoor pollution while band gives people amenities of life, give people health and bring significantly to damage.Indoor pollutant common are formaldehyde, benzene, ammonia, radon etc..Formaldehyde is a kind of main indoor air pollutants in widespread attention, is potential carcinogen generally acknowledged in the world, and, for central nervous system, immune system, liver is all toxic, it might even be possible to trigger allergic disease for the formaldehyde of high concentration.So the improvement of indoor formaldehyde is directly connected to the physical and mental health of people.
The processing method of current PARA FORMALDEHYDE PRILLS(91,95) is mainly divided to two kinds, and one kind is administered from source：Because indoor formaldehyde both typically is from art work, the use of voltage input helmet aldehyde just can reach purpose, but can't industrially completely disengage from formaldehyde at present.Another kind is later regulation technology, mainly there is plant purification method, absorption method and chemical method, and chemical method is including Ozonation, plasma method, photocatalytic oxidation, unglazed metal oxidizing process etc..Wherein again with absorption method and method of chemical treatment effect preferably, but chemical method generally existing immature and high cost the problem of technology, thus at present with it is relatively broad be absorption method.
Activated carbon and NACF are the adsorbents being widely used, and have very flourishing pore structure and big specific surface area, and this causes that they show great advantage on adsorption effect.Activated carbon is difficult fixed-type using simple, low cost, and secondary pollution is also easy to produce in use.Though NACF can solve formation problems, its manufacturing cost is too high, and intensity is again low, should not promote the use.Be mixed into active carbon powder in acrylonitrile-vinylidene chloride stoste by lot of experiments by the present invention, it is fixed on polyacrylic and polyester fiber carrier by the method for spinning, general activated carbon can be solved while activated carbon adsorptive capacity is not damaged and is difficult fixed-type problem.
The present invention is on the basis of previous work, the purified treatment research compared with system is carried out to indoor formaldehyde using this adsorbing fiber, explore the Optimal technique process of the fiber removal formaldehyde, the application for being the polyacrylic and polyester fiber containing activated carbon in terms of purifying indoor formaldehyde provides it is theoretical with practicality in terms of foundation is provided.
The content of the invention
It is an object of the present invention to content of formaldehyde is exceeded in solving the problems, such as existing finishing material and new composite furniture, there is provided a kind of method and Applied Materials that can effectively solve Formaldehyde Pollution of Indoor Air, indoor formaldehyde gas pollution is simply and efficiently removed.
The removal indoor formaldehyde method of the AN-VDC copolymer fibers containing activated carbon that the present invention is provided, the wherein preparation of superfine active carbon powder：Commercially available activated carbon powder is mixed by a certain percentage with DMF, a small amount of dispersant is added, with zirconia ball as abrasive media, stirred in ball mill, obtain certain density super fine activated carbon slurries, filter out the active carbon powder for meeting spinning requirement.The activated carbon micropowder average grain diameter for being adapted to spinning is about 0.7 μm~0.9 μm, and the quality of activated carbon fraction for being added is no more than 30w%.
The preparation of activated carbon AN-VDC copolymer fibers：Above-mentioned active carbon powder is taken, is blended in stirred tank by a certain percentage with acrylonitrile-metachloroethylene copolymer stoste, 8h is stirred at 80 DEG C, deaeration kettle is squeezed into pressure filtration.After deaeration 5h at 70 DEG C, repressurization filtering sprays into spinning coagulation bath through measuring pump by spinning head, and through washing drawing-off after fibre solidification shaping, then through hot water drawing-off, drying winding is made the AN-VDC copolymer fibers containing activated carbon.
Advantages and positive effects of the present invention：The removal indoor formaldehyde method of the AN-VDC copolymer fibers containing activated carbon that the present invention is provided, effectively eliminates Formaldehyde Pollution of Indoor Air thing, and room air is more healthy.
Specific embodiment
Be mixed into active carbon powder in acrylonitrile-vinylidene chloride stoste by lot of experiments by the present invention, it is fixed on polyacrylic and polyester fiber carrier by the method for spinning, general activated carbon can be solved while activated carbon adsorptive capacity is not damaged and is difficult fixed-type problem.
The removal indoor formaldehyde method of the AN-VDC copolymer fibers containing activated carbon that the present invention is provided, the wherein preparation of superfine active carbon powder：Commercially available activated carbon powder is mixed by a certain percentage with DMF, a small amount of dispersant is added, with zirconia ball as abrasive media, stirred in ball mill, obtain certain density super fine activated carbon slurries, filter out the active carbon powder for meeting spinning requirement.The activated carbon micropowder average grain diameter for being adapted to spinning is about 0.7 μm~0.9 μm, and the quality of activated carbon fraction for being added is no more than 30w%.
The preparation of activated carbon AN-VDC copolymer fibers：Above-mentioned active carbon powder is taken, is blended in stirred tank by a certain percentage with acrylonitrile-metachloroethylene copolymer stoste, 8h is stirred at 80 DEG C, deaeration kettle is squeezed into pressure filtration.After deaeration 5h at 70 DEG C, repressurization filtering sprays into spinning coagulation bath through measuring pump by spinning head, and through washing drawing-off after fibre solidification shaping, then through hot water drawing-off, drying winding is made the AN-VDC copolymer fibers containing activated carbon.
By activated carbon micro mist so that in the ratio addition spinning solution of 20w% or so, preferably, the polyacrylic and polyester fiber containing activated carbon for being spinned contains a large amount of holes and their layer of structure is good, and these make fiber have good adsorption function for the spinnability of spinning solution.
Result of study shows that the polyacrylic and polyester fiber PARA FORMALDEHYDE PRILLS(91,95) containing activated carbon has good adsorption cleaning ability.Concentration of formaldehyde be 40 DEG C no more than 8mg/L, adsorption temp, absorption pH be 4 when, fiber obtains optimal adsorption effect, and the clearance of its PARA FORMALDEHYDE PRILLS(91,95) can reach more than 95%.
