Abstract
The invention discloses one kind to remove carbaldehyde Method, set on carrier and remove formaldehyde catalyst coating and catalyst fixed bed, except formaldehyde catalyst coating by mass percent by 20% 40% except formaldehyde catalyst, 15% 46% adhesive, 0 2% thickener and water are made, mass percent total amount is 100%；Catalyst fixed bed is arranged on catalyst coat outer layer, and catalyst fixed bed will be fixed well except formaldehyde catalyst coating, prevent it from coming off, and avoids catalyst exposure and absorb moisture content in atmosphere, reduces the activity of catalyst；Catalyst fixed bed will not will remove formaldehyde catalyst coating covering parcel simultaneously, ensure that the effect except formaldehyde.
Description
Technical field
The present invention relates to one kind to remove carbaldehyde Method.
Background technology
Prior art removes formaldehyde catalyst coating, when making in order to play the effect of catalyst to greatest extent, adds
Adhesive ratio it is less, catalyst coat can come off in use, filter is reduced except formaldehyde performance, and catalyst
The exposure moisture content easily in absorption air in atmosphere, greatly reduce the activity of catalyst；But if add excessive gluing
Agent, or selection adhesive are improper, and catalyst can be completely wrapped again, can not play the effect of it removes formaldehyde.
The content of the invention
In order to overcome prior art easily to be come off except formaldehyde coating, and moisture content in meeting absorption air, influence remove effect of formaldehyde
Deficiency, the invention provides one kind to remove carbaldehyde Method.
The technical solution adopted for the present invention to solve the technical problems is：
One kind removes carbaldehyde Method, including：
Step 1：Allotment removes formaldehyde catalyst coating, should remove formaldehyde catalyst coating and remove first by mass percent for 20%-40%
Aldehyde catalyst, 15%-46% adhesive, 0-2% thickener and water are made, and mass percent total amount is 100%；
Step 2：Formaldehyde catalyst coating will be removed filter surfaces are coated in by spraying or application pattern, and pass through vacuum drying；
Step 3：Catalyst fixed bed is set on except formaldehyde catalyst coating, finally dried.
In above method step, the catalyst fixed bed by mass percent be 10%-70% Aqueous Adhesives,
0.1%-1% thickener, 0-1% defoamer, 0-5% pigment and water are made, and the mass percent total amount is 100%.
In above method step, described filter is cellular, tabular, rugosity, one kind in corrugated or several
The structure of kind combination.
In above-mentioned steps two, vacuum drying step is completed in vacuum chamber.
Drying course in above-mentioned steps three is hot-air seasoning.
The beneficial effects of the invention are as follows：In this method formaldehyde catalyst coating will be removed using catalyst fixed bed well admittedly
It is fixed firmly to prevent it from coming off, and avoid catalyst exposure and absorb moisture content in atmosphere, reduce the activity of catalyst；Urge simultaneously
Agent fixed bed will not will remove formaldehyde catalyst coating covering parcel, ensure that the effect except formaldehyde.
Embodiment
One kind of the present invention removes carbaldehyde Method, is set on carrier and removes formaldehyde catalyst coating and catalyst fixed bed, urged
Agent fixed bed is arranged on catalyst coat outer layer.
The above-mentioned gluing for removing formaldehyde catalyst, 15%-46% except formaldehyde catalyst coating by mass percent for 20%-40%
Agent, 0-2% thickener and water are made, and the mass percent total amount is 100%.
Above-mentioned catalyst fixed bed is 10%-70% Aqueous Adhesives, 0.1%-1% thickener, 0- by mass percent
1% defoamer, 0-5% pigment and water are made, and the mass percent total amount is 100%.
Above-mentioned filter is the structure of cellular, tabular, rugosity, one or more combination in corrugated.
By the above-mentioned catalyst coat prepared be added to by way of spraying cellular, tabular, rugosity or watt
On the carrier of stupefied shape, then dried by vacuum drying chamber, reuse roller the above-mentioned catalyst fixed bed prepared is uniform
It is applied on catalyst coat, coating weight is one side 1.5g/ ㎡, is dried finally by hot air type drier.
Certainly, the present invention can also have the deformation in other steps, these equivalent technologies in addition to above-mentioned embodiment
Scheme should also be as within its protection domain.
