Description
Technical field
The present invention relates to a kind of preparation methods of long-acting renewable methyl aldehyde adsorption material, belong to sorbing material technology of preparing neck
Domain.
Background technology
In recent years, as living standards of the people are gradually increased, air pollution problem inside rooms become increasingly conspicuous, and cause social each
The common concern on boundary.As the formaldehyde of one of main indoor air pollutants, people can be entered by respiratory system and skin
Body has human body potential, universal, long-term harm.Therefore, the purification of formaldehyde in indoor air has important meaning
Justice.Formaldehyde in air is in indoor hardware fitting with continuous, slow way mainly by being released indoors, and indoors
Constantly tired collection, causes indoor formaldehyde concentration exceeded.Therefore, the purification method of formaldehyde needs in the range of long-time effectively.Needle
PARA FORMALDEHYDE PRILLS(91,95) feature present in air indoors, there is an urgent need to study a kind of new method solving formaldehyde pollution.
Amino acid can be reacted with formaldehyde generates hydroxymethyl derivative, harmless to which harmful formaldehyde to be changed into
Substance can be used after suitable carrier loaded amino acid as a kind of novel environment friendly adsorbent, instead of biological can not drop
Traditional sorbing material of solution, avoids secondary pollution from generating.
But at present after common amino acid pattern methyl aldehyde adsorption material amino acid active ingredient wherein and formaldehyde reaction,
Amino acid content reduces, and the adsorption effect of PARA FORMALDEHYDE PRILLS(91,95) also just declines, and effective adsorption time is short, and recyclability is poor, therefore, invention one
The long-acting renewable methyl aldehyde adsorption material of kind has positive meaning to technical field of adsorption material preparation.
Invention content
Present invention mainly solves the technical issues of, for the ammonia of common amino acid pattern methyl aldehyde adsorption material wherein at present
After base acid active ingredient and formaldehyde reaction, amino acid content reduces, and the adsorption effect of PARA FORMALDEHYDE PRILLS(91,95) also just declines, effective adsorption time
Short, the defect of recyclability difference provides a kind of preparation method of long-acting renewable methyl aldehyde adsorption material.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of preparation method of long-acting renewable methyl aldehyde adsorption material, it is characterised in that specifically preparation process is：
（1）It is fitted into wooden barrel, and is moved into greenhouse after pineapple, soybean, squid palpus out and water are mixed, stand mouldy 5~7 days, wait for
It is stirred 10~15min with no bacteria stick after mouldy, obtains mouldy mixture；
（2）Above-mentioned mouldy mixture is transferred in fermentation tank, stands and is sealed by fermentation, obtains tunning, takes out tunning mistake
Filter, isolated ferment filtrate are spare；
（3）It weighs new fresh bean curd and uses the square thumbnail for being cut into that the length of side is 1cm, the thumbnail cut is put into refrigerator,
Freezing processing is taken out freezed bean curd block after freezing processing and is transferred in baking oven, bakes, then the thumbnail after baking is taken out
It is placed on ventilation natural air drying 3~5 days, obtains porous dried bean curd carrier；
（4）10~15min is mixed in spare ferment filtrate and honey and obtains maceration extract, by above-mentioned porous dried bean curd carrier
It is fitted into sonic oscillation instrument after being mixed with maceration extract, sonic oscillation impregnates 1~2h；
（5）After waiting for above-mentioned sonic oscillation dipping, it is separated by filtration to obtain filter residue, as sorbing material crude product, collects cobweb,
After every piece of sorbing material crude product surface 3~5 layers of cobweb of package, package, pack to get long-acting renewable formaldehyde absorbing
Material.
Step（1）Described in pineapple, soybean, squid palpus out and water mass ratio be 3:3:2:10, the temperature in greenhouse is 30
~35 DEG C, relative air humidity be 70~80%.
Step（2）Described in standing be sealed by fermentation temperature be 26~28 DEG C, stand sealing and fermenting time be 2~3
It.
Step（3）Described in the temperature of freezing processing be -15~-10 DEG C, time of freezing processing is 24~30h, is dried
The temperature of system is 105~110 DEG C, and the time of baking is 10~15min.
Step（4）Described in ferment filtrate and honey mass ratio be 10:1, porous dried bean curd carrier and maceration extract
Mass ratio is 1:8, the frequency of sonic oscillation dipping is 35~40kHz.
The beneficial effects of the invention are as follows：
（1）The present invention using rich in amino acid pineapple, soybean, squid palpus out as raw material, they and water co-grinding will crush
Object, which is put into the environment of high temperature and humidity, to be stood mouldy, obtains the crushed material containing mould microorganism, is then sealed anaerobism hair
Raw material degradation is generated amino acid using mould microorganism and is dissolved in ferment filtrate, is separated by filtration to obtain rich in amino by ferment
The ferment filtrate of acid and microorganism, is then made frozen bean curd, is frozen to the cold using moisture in bean curd, the principle that volume becomes larger, will
The support of bean curd internal void is big, has widened the aperture inside bean curd, then bake and be dehydrated through baking oven, and the frozen bean curd for obtaining high porosity is dry
As adsorbing agent carrier, the viscosity of the invention later with honey increase ferment filtrate, and it is adsorbing agent carrier by ultrasonic immersing
Ferment filtrate is loaded, finally wraps up the carrier for loading ferment filtrate up to long-acting renewable formaldehyde absorbing material by cobweb
Material, the present invention are made in formaldehyde adsorbent, since the dry carrier of porous frozen bean curd has porosity characteristic, large specific surface area, load byte
Point is more therefore stronger to the formaldehyde absorbing ability in air, and the package of later stage spider silk makes sorbing material surface carry one
The loose porous spider's thread layer of layer, further improves sorbing material specific surface area, improves its absorption property again, inhaled by carrier
In attached formaldehyde meeting and carrier hole or the ferment filtrate of area load contacts, and the amino acid in ferment filtrate can be sent out with formaldehyde
Raw reaction generates hydroxymethyl derivative, and harmful formaldehyde is changed into innocuous substance, plays the role of purifying formaldehyde, and
With the increase of formaldehyde absorbing amount, the amino acid quantity in ferment filtrate is also being reduced, and the microorganism in ferment filtrate opens at this time
Beginning plays a role, and since the ingredient of bean curd and cobweb is largely protein, protein fibre can be in the effect of microorganism
Lower generation slowly degradation, and new amino acid is gradually generated, these newly generated amino acid can make up in amino acid extracting solution
The part lost is reacted with formaldehyde, to extend the effective acting time of scavenger, reaches the term of validity for extending scavenger
Purpose, and the amino acid layer after formaldehyde adsorption aging and can layer by layer fall off under the action of microorganism, expose internal new ammonia
Base acid layer continues adsorption cleaning formaldehyde, which thereby enhances the renewable performance of methyl aldehyde adsorption material of the present invention, has wide answer
Use foreground.
