Abstract
The invention discloses a method for eliminating formaldehyde, comprising the following steps of: (1) diluting a formaldehyde elimination agent used in the method disclosed by the invention for 1000 times; and (2) spraying the diluted solution on the surfaces of plates, furniture or home decoration. The formaldehyde elimination agent used in the method disclosed by the invention can achieve greater than 93% of formaldehyde removal rate and cannot cause secondary pollution.
Description
Technical field
The present invention relates to a kind of formaldehyde removing method.
Background technology
Formaldehyde is a kind of colourless poisonous gas.Formaldehyde in the house fitting-up is mainly concealed in clamping plate, lumber core, the household that high-density plate is made, timber floor etc.Because formaldehyde has stronger cohesive, also have the hardness of strengthening sheet material and insect protected, corrosion-resistant function, so be used for synthetic multiple adhesive.Gradually towards periphery environment release of formaldehyde residual or that have neither part nor lot in reaction forms airborne formaldehyde in the sheet material.The glue-line that the has solidified cracking of also can degrading under certain condition discharges formaldehyde.Temperature is higher, and burst size is larger.Formaldehyde can absorb through respiratory tract, and it damages body by causing tissue active oxygen increase, peroxidatic reaction of lipid, the immune system that affects body and large biological molecule effect etc.Formaldehyde has spread effect to skin and mucosa, and human body is had sensitization, can cause allergic dermatitis, color spot, bronchial astehma etc.It also has strong carcinogenicity and short canceration, can cause for example nasopharyngeal carcinoma and leukaemia.Along with the day by day raising of people's living standard, interior decoration is very general.The formaldehyde pollution problem has caused people's extensive concern.Sell in the market except formaldehyde property right product mostly just a kind of " surface-closed agent ", rather than truly " methanal disintegrant ".It forms the release of the temporary transient closed methanal of a skim at sheet material or furniture surface, in case this film owing to make moist or meet heat and suffer that skin cherishes, formaldehyde will come out again.Therefore, effectively remove the formaldehyde pollution that is caused by interior decoration and become problem in the urgent need to address.
Summary of the invention
The purpose of this invention is to provide a kind of formaldehyde removing method, formaldehyde can be transformed and be degraded into nontoxic material, effectively alleviate free formaldehyde to the pollution of room air, and can not cause secondary pollution.
Formaldehyde scavenger of the present invention is comprised of following component by weight:
The applicant through repeatedly, deep experimental study just draws the formaldehyde scavenger that adopts above-mentioned prescription.The aldehydes removal rate of this scavenger can reach more than 93%, is higher than the like product on the market, is the crystallization that the applicant pays a large amount of painstaking effort.
The preparation method of above-mentioned formaldehyde scavenger may further comprise the steps:
(1) 100-115 part water, 1-3 part hydrogen peroxide and 3.3-5.6 part glycine are mixed, constantly stir until all components dissolves fully;
(2) continue to add 1.5-5 part photocatalyst and 0.05-0.1 part NaOH, stirred 1-2 hour, get product.
Formaldehyde removing method of the present invention may further comprise the steps:
(1) formaldehyde scavenger that adopts the component by following weight portion to form:
(2) with 1000 times of described formaldehyde removing dilution agents;
(3) solution spraying with dilution gets final product in the surface of sheet material, furniture or home decoration.
