Description
Technical field
The utility model is related to field of compound material, belong to a kind of sand for realizing purifying formaldehyde gas by generating anion
Mould plate.
Background technology
It is well known that a large amount of coating and adhesive can be used during the finishing in house, and coating and adhesive
In can usually contain a large amount of formaldehyde.Indoor air formaldehyde content can be caused exceeded in this way, to cause the damage to human body.Mesh
The preceding common method for removing indoor formaldehyde pernicious gas is mainly physical method and chemical method.Wherein physical method is to use
The porous materials such as activated carbon adsorb indoor formaldehyde gas, to realize the effect for reducing indoor harmful gas content.But
It is this quadrat method, due to the limited sorption capacity of activated carbon, so the removing of PARA FORMALDEHYDE PRILLS(91,95) is not highly desirable.Chemical method is main
It is to have reached the effect for removing the harmful substances such as indoor formaldehyde by using chemical reagent such as formaldehyde scavengers.But this kind of side
Although method can timely remove the formaldehyde in room air, the formaldehyde being adsorbed in construction material can not be removed.
Since the mode of above-mentioned removing indoor formaldehyde is all there are larger defect, and then research is removed indoor first by people
On the directional steering of aldehyde finishing material.For example, to disclose a kind of PVC wood plastic compound by Chinese patent literature CN104895285A
