Abstract
The utility model discloses formaldehyde rapid detection test paper. The paper comprises a plastic housing, test paper (4), a plastic bottle (5) and a color comparison card (6), wherein the plastic housing is divided into a base plate (2) and a surface plate (1), a test window (3) is arranged on the surface plate (1), the test paper (4) is loaded with a formaldehyde enrichment agent, formaldehyde color comparison liquid is filled in the plastic bottle (5), the color comparison card (6) is provided with color gradations, each of the color gradations indicates corresponding formaldehyde concentration, and the test paper (4) is clamped at a position of the test window (3) between the base plate (2) and the surface plate (1) of the plastic housing. The formaldehyde rapid detection test paper is easy to operate, convenient to use and is suitable for the semi-quantitative detection of microscale formaldehyde in the air in the field of environment detection and the semi-quantitative detection of formaldehyde in the air near homes or furniture, and the application prospects are broad.
Description
Technical field
The utility model relates to a kind of formaldehyde quick detection test paper, and the kit of air formaldehyde concentration in particularly a kind of disposable sxemiquantitative on-the site analysis measuring cell belongs to the product that on-the site analysis detects.
Background technology
Current society, people value the right to know of oneself very much, and anything is all wondered principle, essence, all hope oneself " seeing is believing ", and the understanding according to oneself provides evaluation then.No exception in air purification field, a lot of consumers wonder how many indoor pollutants has on earth, and harm has much; After having understood these,, whether need buy purified product according to the judgement of oneself; After buying back purified product, wonder again whether purified product acts on, and how many pollutants removed ..., common people's consumer behavior just produces after all being based upon and oneself recognizing existing problems, rather than because businessman say demand arranged, market is just arranged.
At present, air purifier market is being faced with this situation, and on the one hand manufacturing firm's propaganda air purifier is the requisite electrical equipment in finishing back, can remove the pollutants such as formaldehyde, benzene of the disease of the weight that causes that people's life can not bear; On the other hand, because the complicacy of pollutant, machine can not thoroughly be removed, and has caused the suspection of consumer to the air purifier effect.Air purification is in the cognitive stage in China, and common people's this consumer psychology has clearly hindered the developing in air purification market.Though on the market special air pollution testing agency is arranged now; But not wanting to survey just survey because the high price of its appearance of hundreds of easily units is not the consumer, is very important so testing product simple, convenient, that price is low acts in air purification market development process.
The utility model content
The purpose of the utility model is deficiency and the actual needs to prior art, and a kind of formaldehyde quick detection test paper is provided, and the technology of low concentration formaldehyde in a kind of ability fast detecting air particularly is provided.This utility model is simple in structure, and is easy to use, reliable rapidly.
The utility model technical scheme:
A kind of formaldehyde quick detection test paper comprises and moulds shell, test paper (4), plastic bottle (5) and colorimetric card (6); Mould shell and divide base plate (2) and panel (1), a testing window (3) is arranged on the panel (1), test paper (4) load has the formaldehyde pregnant solution, and formaldehyde colour developing liquid is housed in the plastic bottle (5), and colorimetric card (6) has color range, and each color range has been indicated corresponding concentration of formaldehyde; Test paper (4) is stuck in the testing window of moulding between shell base plate (2) and the panel (1) (3) and locates.
Described formaldehyde quick detection test paper, the plastics (5) that formaldehyde colour developing liquid is housed are installed in moulds in the middle of shell base plate (2) and the panel (1), and plastic bottle (5) liquid outlet end is located at testing window (3), the bottle of plastic bottle (5) over against the shell panel of moulding have and push window (7).
During use, puncture plastic bottle liquid outlet end with sharp object, extruding plastic bottle bottle is added drop-wise to developer on the test paper, is placed in the air 1 to 30min, with the colorimetric card colorimetric, and the concentration that can read formaldehyde in the air.The disclosed product operation of the utility model is simple, and is easy to use, is fit to the half-quantitative detection of trace formaldehyde in the air of environment measuring field, also is applicable to the half-quantitative detection of formaldehyde in family, near the air of furniture, has a extensive future.
The utility model beneficial effect is embodied in:
1. the operation of conventional art multistep is concentrated on the test paper, simple to operate, and do not need the large-scale instrument and equipment analytical test, cost is low, is applicable to ordinary people family;
2. can be on-the-spot sxemiquantitative test air formaldehyde concentration, in 1 to 30min with colorimetric card relatively, directly read air formaldehyde concentration, easy to use;

Fig. 1 is the structural representation of formaldehyde quick detection test paper among the embodiment 1;
Fig. 2 is the structural representation of formaldehyde quick detection test paper among the embodiment 2.
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
Embodiment 1:
Like Fig. 1, a kind of formaldehyde quick detection test paper of the utility model comprises and moulds shell, test paper 4, plastic bottle 5 and colorimetric card 6.Mould shell and divide base plate 2 and panel 1; One testing window 3 is arranged on the panel 1; Test paper 4 loads have formaldehyde pregnant solution (for example, triethanolamine potassium metaperiodate solution), formaldehyde colour developing liquid are housed (for example in the plastic bottle 5; 4-amino-3-hydrazine-5-sulfydryl triazole), each color range of colorimetric card has been indicated corresponding concentration of formaldehyde.Test paper 4 is stuck in testing window 3 places of moulding between shell base plate 2 and the panel 1.During use, puncture 5 mouthfuls of the plastic bottles that developer is housed, squeeze a colour developing liquid to test paper with sharp object; Be exposed in the environment to be measured, formaldehyde is enriched in test paper 4 surfaces and the reaction of colour developing liquid, and color changes; Through comparing, judge tested air formaldehyde concentration with colorimetric card 6.
Embodiment 2:
Like Fig. 2, different with embodiment 1 is, the plastics 5 that formaldehyde colour developing liquid is housed are installed in to be moulded in the middle of shell base plate 2 and the panel 1, and plastic bottle 5 liquid outlet ends are at testing window 3 places, plastic bottle 5 bottles over against the shell panel of moulding have extruding window 7.During use,, to test paper, be exposed in the environment to be measured through extruding window 7 crowded colour developing liquid, formaldehyde is enriched in test paper surface and developer reaction, and color changes, and through comparing with colorimetric card, judges tested air formaldehyde concentration.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims according to above-mentioned explanation.
