Description
Technical field
The present invention relates to a kind of room temperatures except formaldehyde materials, more particularly to it is a kind of load biological enzyme except formaldehyde composition and its
Preparation method.
Background technology
Formaldehyde is one of common air pollutants of modern society, is mainly derived from indoor plank, wall covering, plastic cement system
Product.Formaldehyde is mainly strong carcinogenesis and strong mutagenicity to the harm of human body.Long Term Contact formaldehyde can cause respiratory tract, digestion
The mucosa infection in road, and then lead to lung function and dysfunction of liver, immune system is finally influenced, generates canceration.Children and pregnant woman
The reaction of PARA FORMALDEHYDE PRILLS(91,95) is especially big, therefore formaldehyde is listed in China's toxic chemical priority acccess control list second.
The minimizing technology of formaldehyde includes the methods of physical absorption, chemical catalysis, chemical reaction, living things catalysis, most often at present
What is seen is the composition adsorption method in physical absorption.Composition absorption method is mainly special using the high-specific surface area of composition
Property, come the purpose realized fully absorption, decompose formaldehyde in air.It is advantageous that porous material large specific surface area, can load more
More biological enzyme, therefore can realize more efficient suction-operated.Market it is common usually carry heavy metal except formaldehyde composition
The industrial chemicals such as oxide or pitch, tar are likely to cause the pollution of environment during producing and using, directly exposed to connect
Touching also has certain danger.
Invention content
The purpose of the present invention is to provide a kind of carrying biological enzyme except formaldehyde composition preparation method, it is mainly used for first
Aldehyde gas effective protection.In view of the possible pollution on the environment of heavy metallic oxide, present invention employs biological enzymes
Principle.This method is mainly a large amount of active formaldehyde dehydrogenases by being attached on porous material micropore, by the first in air
Aldehyde is converted into harmless formic acid, and then realizes the purpose for eliminating formaldehyde.Since formaldehyde dehydrogenase plays catalyst during the reaction
Effect, the consumption of enzyme is less in reaction process, therefore the drying that only needs periodically to divulge information can restore to remove formaldehyde activity again.
To achieve the above object, the application provides following technical solution：
A kind of formaldehyde composition that removes for loading biological enzyme, it is described except formaldehyde composition uses porous material as carrier, thereon

Having the beneficial effect that prepared by the present invention：
1. except the system for handling bigger of formaldehyde composition PARA FORMALDEHYDE PRILLS(91,95).The physical absorption of conventional composition is that a dynamic is put down
Weighing apparatus process, after the treating capacity for reaching certain, the adsorbance and burst size of formaldehyde are equal, that is, have reached the threshold value of adsorption capacity.
And the preparation-obtained composition of the present invention is due to large specific surface area, increases the load capacity of biological enzyme, formaldehyde be adsorbed onto it is more
After the microcellular structure of Porous materials, harmless formic acid is converted under the action of formaldehyde dehydrogenase quickly and is volatilized from system, so as to
Greatly promote the adsorbance of composition PARA FORMALDEHYDE PRILLS(91,95).
2. with it is commercially available except formaldehyde composition compared with, the present invention do not use the chemical industry such as heavy metallic oxide and pitch, tar
Raw material, and it is mild in working condition, and product has the characteristics that environment friendly and nonhazardous, can be commonly used to a variety of fields
It closes.
3. the present invention is added to nano-titanium dioxide in preparation process, the ingredient is under the conditions of natural lighting, it may have
Certain chemical catalysis Degradation Formaldehyde effect.Formaldehyde hand is removed present invention incorporates physical absorption, chemical catalysis and living things catalysis
Section, except formaldehyde sales volume greatly promotes.
4. prepared by the present invention except formaldehyde composition in use for some time, activity may decrease, this be by
Other impurities or moisture contamination in adsorbance gradually saturation and environment, ventilation drying can activity recovery.
