Description
Technical field
The present invention relates to formaldehyde examination technical fields, detect more specifically to a kind of biological respinse type indoor formaldehyde
Method.
Background technique
Formaldehyde is colourless aqueous solution or gas, irritant smell.Soluble easily in water and ether, concentration of aqueous solution reach as high as
55%, pH value: 2.8-4.0., it can be miscible in any proportion with water, ethyl alcohol, acetone and other organic solvent.Liquid is store long when colder
It is easily muddy, metaformaldehyde precipitating is then formed in low temperature.Some formaldehyde escapes when evaporation, but majority becomes metaformaldehyde.
The product are strong reductant, and in micro alkalinity, reproducibility is stronger.Formic acid can be slowly aoxidized in air.The main harm of formaldehyde
It shows as to mucocutaneous stimulation.When formaldehyde reaches a certain concentration indoors, people just has sense of discomfort, is greater than 0.08mg/
The concentration of formaldehyde of m3 can cause to be envious, eye is itched, throat discomfort or pain, hoarseness, sneeze, uncomfortable in chest, asthma, dermatitis etc..Newly
The room content of formaldehyde of finishing is higher, is the main inducing of numerous diseases.
Existing indoor formaldehyde results from glued board, core-board, medium density fibre board (MDF) and the wood shavings of interior decoration mostly
The artificial boards such as plate, formaldehyde that is remaining in plate and having neither part nor lot in reaction can gradually be discharged to ambient enviroment, form room air
