Description
Technical field
the present invention relates to a kind of formaldehyde tester, particularly relate to a kind of Household fixed-type formaldehyde tester.
Background technology
the main harm of formaldehyde shows as Mucocutaneous spread effect.Formaldehyde is when indoor reach finite concentration, and people just has sense of discomfort, the concentration of formaldehyde being greater than 0.08m3 can cause furious, eye is itched, throat discomfort or pain, hoarseness, sneeze, uncomfortable in chest, asthma, dermatitis etc.Newly-decorated room content of formaldehyde is higher, is the main inducing of numerous disease.When concentration of formaldehyde reaches 0.06 ~ 0.07mg/m3 in every cubic metres of air, will there is slight asthma in children; When formaldehyde in indoor air reaches 0.1mg/m3, just there are peculiar smell and sense of discomfort; When formaldehyde reaches 0.5mg/m3, can eyes be stimulated, cause and shed tears; Formaldehyde reaches 0.6mg/m3, can cause throat discomfort or pain.When concentration is higher, can cause nausea vomiting, coughs uncomfortable in chest, even pulmonary edema of panting; When formaldehyde reaches 30mg/m3, meeting causing death immediately.
formaldehyde is a kind of colourless, and have the gas of intense stimulus type smell, it is very large to the injury of human body.Formaldehyde is present in building products more, as coating, paint etc.At present, for formaldehyde examination, general way carries out centralized detecting after house decoration, and the formaldehyde that this method is difficult to determine to exceed standard is which product produced, even and if trace specific product, cause product to be difficult to change or remove because completing finishing again.And, the mode of the detection formaldehyde of existing employing adopts formaldehyde tacheometer, and the formaldehyde in some product, to dissipate completely after certain time intervals, do not need to carry out the replacing of product or dismounting, therefore, adopt formaldehyde tacheometer will certainly the misreading of people's PARA FORMALDEHYDE PRILLS(91,95) content, and then cause the waste of a large amount of building materials.
at present, in formaldehyde method of testing, at the scene in test, spectrophotometric method limit by the operating conditions such as water-bath or the concentrated sulphuric acid; Though vapor-phase chromatography is more accurate but be only applicable in lab analysis, and expensive equipment, not easily apply.Along with the raising day by day of the living standard of people, people need a kind of simple, sensitive, portable formaldehyde tester fast and accurately.
