Abstract
The present invention relates to a production method of a coloring air filter. An air filtering layer, a purifying layer and a coloring layer are respectively arranged in an outer shell, wherein the coloring layer is formed by a method that the pH value of a coloring agent solution is regulated by an acidic solution; then, adsorption material is added for soaking and drying; the obtained product adheres to porous base material by an adhesive. The present invention has the advantages of simple manufacture process and convenient technology. The service life of the air filter can be displayed by the color change of the coloring layer; the present invention also has the advantages of simple and visual method, remarkable effect, safety and no toxin. The present invention has wide range of application, and can be suitable for air fresheners and household and central air conditioners.
Description
Technical field
The present invention relates to the air purifying process field, more specifically to a kind of manufacture method of air cleaner.
Background technology
At present, people are more and more to the understanding of the harm that indoor air environment pollutes, and all use air cleaner in a lot of occasions, the particularly new dwelling house of decorating, office, air pollution occasions such as smoking institute place.And existing air cleaner all only indicates dedusting, the functions such as smelly, sterilization that disappear, and all be relatively fuzzy notion service life, clearly specifically how long can not use, and whether filter has the deodorization functions people and can not judge intuitively.After the activated carbon filtration material reached the i.e. inefficacy of maximum saturation absorption, people when need not to know to change, and like this, air cleaner can produce secondary pollution on the contrary, can not really play the purpose of protection human body health.
Summary of the invention
Technical problem to be solved by this invention be overcome provide in existing deficiency a kind of method simple, make easily, have the manufacture method of the colouring air filter in service life directly perceived.
The present invention can take following technical measures to solve:
By above-mentioned purpose, a kind of colouring air filter can be made by following method:
In square, a circular or well-regulated geometric shell, the air filtration layer is installed earlier, on the air filtration layer, is put purifying layer, color layer is installed on purifying layer again, the air filtration layer adopts the nonwoven that has static, makes shell shape by folding mode.Purifying layer adopts active carbon, and it is online at polyester fiber that the adding adhesive makes it appendix.
Above-mentioned color layer be 20-40% can with the chromogenic reagent solution of pernicious gas variable color in, with stirring behind the acid solution adjusting PH=3-6, adding sorbing material again soaked 30--60 minute, taking out drying is Powdered or graininess, again sorbing material is sticked with glue the agent appendix on porous substrate, can obtain color layer.
Outstanding effect of the present invention is:
1), manufacture method of the present invention is simple, technology is easy.
2), can know service life of air cleaner to see intuitively whether filter can be removed airborne pernicious gas by the change color of color layer, the method simple, intuitive, effect is obvious, safety non-toxic.
3) purposes of the present invention is wide, applicable to air cleaner, and family expenses and central air-conditioning.
The specific embodiment
Embodiment 1
In a square shell, the air filtration layer is installed earlier, on the air filtration layer, put purifying layer, install color layer at purifying layer again.The air filtration layer adopts the polypropylene non-woven fabric that has static, makes shell shape by folding mode.Purifying layer adopts column-shaped active carbon, and it is online at polyester fiber that the adding adhesive makes it appendix.Color layer is in 20% liquor potassic permanganate, adds to stir after 10% sulfuric acid is regulated PH=3, adds zeolite molecular sieve again and soaks 35 minutes, takes out drying and is Powdered.Again zeolite molecular sieve is used PU adhesive appendix on the ceramic honeycomb sheet.Can obtain color layer.
Embodiment 2
In the shell of a circle, circular air filtration layer is installed earlier, on the air filtration layer, put purifying layer, install color layer at purifying layer again.The air filtration layer adopts the PP nonwoven that has static, makes shell shape by folding mode.Purifying layer adopts the active carbon of sheet, and it is online at polyester fiber that the adding adhesive makes it appendix.Color layer is in 40% fuchsin solution, adds to stir after 20% hydrochloric acid solution is regulated PH=6, adds zeolite molecular sieve again and soaks 60 minutes, takes out drying and is graininess.Again that zeolite molecular sieve is online at polyester fiber with PU adhesive appendix.Can obtain color layer.
Using method:
The colouring air filter of making is installed in the machinery equipments such as refrigerator, air-conditioning, air cleaner, humidifier and uses.
Claims (2)
1, a kind of colouring air filter manufacture method, square at one, in the circular or well-regulated geometric shell, the air filtration layer is installed earlier, on the air filtration layer, put purifying layer, the air filtration layer adopts the nonwoven that has static, make shell shape by folding mode, purifying layer adopts active carbon, it is online at polyester fiber that the adding adhesive makes it appendix, it is characterized in that: color layer is installed on purifying layer, color layer be 20-40% can with the chromogenic reagent solution of pernicious gas variable color in, with stirring behind the acid solution adjusting PH=3-6, add sorbing material again and soaked 30--60 minute, take out drying and be Powdered or graininess, again sorbing material is sticked with glue the agent appendix on porous substrate, can obtain color layer.
2, a kind of colouring air filter manufacture method according to claim 1, it is characterized in that: above-mentioned color layer preparation method is in 30% liquor potassic permanganate, with stirring behind the 10% sulfuric acid solution adjusting PH=5, adding zeolite molecular sieve again soaked 50 minutes, take out drying and be graininess, it is online at polyester fiber zeolite molecular sieve to be sticked with glue the agent appendix again, can obtain color layer.
