Background technology
Nowadays, increasing finishing pollution and increasing haze flue gas etc. annoying the life cycle of present urban human
Border, such as formaldehyde, flue gas etc. enjoy people to pay close attention to, and also always search for a kind of natural filtering that can purify pollutants in air
Medium.
Air purification medium has that aperture is small, and its gap is typically between 0.2-1.5um, even aperture distribution, porosity
Greatly, typically more than 95%, while maintaining the circulation of air, all dust granules including bacterium can be filtered, are reached
Purification and the purpose of ventilation.Traditional air purification medium is using polytetrafluoroethylene (PTFE) as raw material, and one is formed after expanded stretching
Kind there is micro porous film, turn into novel filter material on various fabrics and base material by this film special process is laminating,
The membrane aperture is small, is evenly distributed, and porosity is big, while maintaining the circulation of air, can filter all including bacterium
Dust granules, reach the purpose of purification and ventilation, it is widely used in the fields such as pharmacy, biochemistry, microelectronics and laboratory consumptive material.
Purple willow is that Salicaceae Salix is grown thickly machaka for many years, and well developed root system, adaptability are extremely strong, drought resistance and resistance to overhead flooding injury
It is stronger.Purple willow is distributed widely in fluvial outwash, the river terrace of alluvial moistening.Purple willow not only has clockwork spring rate height, wicker elongated, rich
The good characteristics such as flexible, and can check winds and fix drifting sand, conserve water and soil, shore protection, bank protection, develop purple willow using low-lying land, because of ground
Develop to suiting measures to different conditions wetland specialty industries, can effectively evade the risk of natural calamity, avoid, reduce and reduce flood pair
Destruction and adverse effect along Huaihe River low-lying land agricultural production, be directly connected to along Huaihe River low laying areas broad masses of the people livelihood and
The sustainable development of economic society, it is to keep away calamity mitigation along Huaihe River low-lying land agricultural, increase income the important channel of synergy.Meanwhile develop Qi
Willow can also improve land resources utilization rate, promote the ecological balance.
Purple willow light is shone, and belongs to heliophilous species.Illumination deficiency, growth are bad.It is born in mountain region river bank, wet meadow.Purple willow is manurial-philous
Water, anti-waterlogging caused by excessive rain is best to be grown in the deep sandy loam in upper strata and irrigation canals and ditches side slope, thus should select sandy loam, flood land with
And the place plantation that irrigation canals and ditches side slope of nearly water etc. is fertile.Fertilizer and water condition is good, and shoot growth is vigorous, can be with normal growth 20~30
Year.Under the conditions of drought and barren soil, shoot growth is thin and delicate short and small, the lost of life.In the shallow ponding unfavorable conditions of 2~3 months
Under, remain to normal growth.Purple willow Salt And Alkali Tolerance poor-performing, soil salt content is such as more than 0.3%, then shoot growth weakens.
Purple willow bar is typically gathered in late July to early August fair weather.GPRS is with cutting bar with peeling.Peeling
Before to prepare the clip made with waddy, branch following is first peeled off some skins, is placed in clip, is then taken out from thick head to thin head
Draw, obtain informal voucher.Dried in time after stripping, the branch after drying is bundled by thickness grading, storage.Storage period prevents sootiness, made moist,
In order to avoid the mouldy discoloration of branch.
Purple willow after treatment, is prepared the medium that can remove formaldehyde and flue gas, the fibrous material energy by the utility model
Formaldehyde in air and flue gas are enough filtered, while there is higher safety and stability.
Utility model content
Inventor is by the characteristic to purple willow wood fibre and correlative study, it is proposed that it is a kind of it is brand-new can remove formaldehyde and
The air purification medium of flue gas, the cross-section structure of the air purification medium are as shown in Figure 1.
The purple willow air purification medium is bonded by 5 layer materials, is respectively from top to bottom：Teflon membrane filter layer
1, konjaku glue-line 2, purple willow fabric layer 3, konjaku glue-line 4 and teflon membrane filter layer 5.
Wherein, the teflon membrane filter layer 1 is that process is expanded using polytetrafluoroethylene (PTFE) as raw material, rolled, biaxial tension
Forming one kind afterwards has micro porous film layer, is a kind of high polymer material.
The konjaku glue-line is after konjac glucomannan is dissolved in into water, by 75 ~ 80 DEG C of heat treatments, then smears the thin of flat board formation
Film, its thickness are 0.1 ~ 2mm.
The specific preparation method of the purple willow fabric layer is as follows：
Strip purple willow stem is taken, is soaked 1 ~ 2 hour with 0.1 ~ 0.3% sulfur dioxide solution, obtains strip purple willow stem.
Strip purple willow stem is placed in 2 ~ 5%（m/V）Citric acid solution in soak 3 ~ 8h, obtain the purple willow after citric acid treatment
Stem.
Purple willow stem after citric acid treatment is drained, after be put into 3.5 ~ 6%（m/V）NaOH solution in soak 5 ~ 10h.
Under conditions of purple willow stem after naoh treatment is placed at into 55 ~ 70 DEG C, 3 ~ 5h of heated-air drying.
By purple willow fiber with 100 ~ 105 DEG C of vapor 15 ~ 30min of boiling, after boiling, 0.5 ~ 2% biphosphate is put into
4 ~ 8h is soaked in aqueous solutions of potassium.
Purple willow fiber is prepared into purple willow fiber textile, and purple willow fiber textile is placed in 255 ~ 260 DEG C of condition
Under, 1 ~ 3h of forced air drying, obtain purple willow fabric layer.
Beneficial effect
The utility model will be discarded extensively, and the purple willow for log is subject to deep processing, obtain it is a kind of have except formaldehyde and
The air purification medium of flue gas, can be used in air purifier, there is provided a kind of natural nontoxic purification of air is situated between
Matter.
Purple willow air purification medium PARA FORMALDEHYDE PRILLS(91,95) and flue gas of the present utility model have good adsorption effect, by inventor
Detection, will contain 1%（V/V）Formaldehyde air with 1m3/ min speed passes through the air purification medium, its formaldehyde percent of pass
3.82%, it is seen that purple willow air purification medium provided by the utility model has the effect except formaldehyde；Similarly, 3% will be contained（V/V）
