Description

A kind of coating removing formaldehyde
Technical field
The present invention relates to a kind of coating, particularly a kind of coating removing formaldehyde.
Background technology
Formaldehyde is more highly toxic material, and on Chinese noxious chemical priority acccess control list, formaldehyde is in second.Formaldehyde has been defined as carcinogenic and cause deformed material by the World Health Organization, be generally acknowledged allergen, is also one of potential strong mutagen.Research shows, formaldehyde has strong carcinogenic and tumor promotion.The impact of formaldehyde on HUMAN HEALTH is mainly manifested in the aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction.Its concentration reaches 0.06-0.07mg/m in atmosphere 3time, slight asthma will be there is in children.When formaldehyde content in indoor air is 0.1mg/m 3time, just there are peculiar smell and sense of discomfort; Reach 0.5mg/m 3time, can eyes be stimulated, cause and shed tears; Reach 0.6mg/m 3, throat discomfort or pain can be caused.When concentration is higher, can cause nausea vomiting, coughs uncomfortable in chest, even pulmonary edema of panting; Reach 30mg/m 3time, meeting causing death immediately.
Long Term Contact low dosage formaldehyde can cause chronic respiratory tract disease, also can cause nasopharyngeal carcinoma, colorectal carcinoma, brain tumor, menoxenia and nuclear transgenation, also can to cause in DNA single chain commissure and DNA and protein commissure and suppress the reparation of DNA damage, pregnancy syndrome, cause neonatal chromosome disorder, leukemia etc., teenager's memory and intelligence also can be caused to decline.In all contactees, children and pregnant woman's PARA FORMALDEHYDE PRILLS(91,95) particularly responsive, harm is also just larger.According to the display of related data statistics: the mankind have the illness of 70% relevant with indoor environment, and China has 120,000 people to die from indoor pollution every year, the child leukaemic of more than 90% lives in new clothes and repairs the house ill in 1 year.
At present, the method removing formaldehyde mainly contains following several:
1) ventilation
Ventilation is exactly the flowing by air, and obnoxious flavour is discharged to outdoor, and this is a kind of simple effective method, and unique weak point is that the Form aldehyde release cycle is long, generally takes 3 years to 15 years, by obviously unrealistic for more than the 3 years free time of new house after finishing.Be stranded this, depend merely on ventilation and also do not reach the requirement of removing formaldehyde.
2) charcoal absorption
The use initial stage of gac is really effective, because hole has adsorption potential, lean on carbon molecule and formed by the gravitation of binding molecule, aperture is less, and adsorption potential is stronger.In addition, according to kinetic molecular theory, all objects, by molecule or atom composition, have gap between them, and be in again eternal unrestrained random thermal motion state, intermolecular mutual collision is very frequent simultaneously.From pertinent data display, in normal conditions, the free movement speed of formaldehyde molecule is about 450 meter per seconds, a formaldehyde molecule and other molecules are per second will collide 109 times.Now, if the diameter of colliding molecule mates with gac hole, will be adsorbed.No matter be traditional gac, or the modified activated carbon propagandizing often at present, all cause limited sorption capacity because its hole is excessive.
3) with water, vinegar, black tea is soaked removes formaldehyde
A lot of people introduces, and because formaldehyde is water-soluble, can stay at home and put several basin more and be used for absorbing formaldehyde, or by vinegar or the method such as black tea is soaked.
Formaldehyde is soluble in water, alcohol and ether this be true, can dissolve in wherein after running into water in the free formaldehyde moving process in air, this is substantially identical with the absorption principle of gac.The contact area of one basin water and air only has the size of basin, and the specific surface area of 1 gram of gac internal void can to reach a football pitch so large.Even if put 100 basin water in room, its adsorption effect can not be more how many by force than a parcel gac.Therefore utilizing the methods such as water, black tea, vinegar to carry out formaldehyde adsorption, is obviously also unpractical.
4) photocatalytic method
Photocatalyst is under the irradiation of light, similar photosynthetic light-catalyzed reaction can be produced, produce the extremely strong free hydroxy of oxidation capacity and active oxygen, there is very strong photoredox function, the various organic compound of oxidable decomposition (as formaldehyde) and part inorganics, the cytolemma of bacterium and the protein of solidification virus can be destroyed, can kill bacteria Sum decomposition organic pollutant, organic pollutant is resolved into free of contamination water (H 2o), carbonic acid gas (CO 2) and other innoxious substance, thus there is extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, air purification function.
5) fruit such as orange, pineapple formaldehyde adsorption
This is the method that past a lot of people likes, and can be described as an indigenous method among the people.Why a lot of people feels to use pomelo peel, and after pineapple, indoor finishing taste is little, and that because the taste of fruit covers the taste of formaldehyde covers, and formaldehyde there is no obvious minimizing.
6) plant absorption formaldehyde
Plant can pass through photosynthesis suction part objectionable impurities, but the effect of these class methods is very limited.Reason is as follows:
What one, plant carried out is photosynthesis, generally suction part objectionable impurities by day, and does not possess this function at night.The rule of life of people is all generally that daytime is outdoor, and night, when people needs most purifying air, plant had no idea to play corresponding effect in indoor.
Two, the objectionable impurities of plant absorption is very limited.The releasing value of national standard PARA FORMALDEHYDE PRILLS(91,95) requires lower than 0.08 milligram/cubic metre, the house that the overwhelming majority has just been fitted up, and formaldehyde is not less than 0.2 milligram/cubic metre, and absorbs the higher epipremnum aureum of formaldehyde efficiency, and the formaldehyde of absorption per hour is only 20 micrograms.With 100 square meters, room is high 3 meters, formolite number is the room of 0.2 milligram/cubic metre, need 1800 basin epipremnum aureums simultaneously, almost space, whole house to be filled, formaldehyde could be reduced to 0.08 milligram, this still carries out in well-lighted situation by day, and will ensure in the release carrying out no longer including in the process absorbed formaldehyde.And in fact, the formaldehyde in the furniture after finishing is also constantly discharging always.Therefore, plant only the objectionable impurities such as PARA FORMALDEHYDE PRILLS(91,95), benzene can play auxiliary governance role.
7) air purifier is except formaldehyde
All purification efficiencies of air purifier calculate and all complete in laboratory, be measure gained when getting rid of chronic pollution source, that is, these data all obtain meeting under specified conditions, therefore in actual use, purification efficiency can than manufacturers declare lower.Essentially, air purifier just plays a kind of effect of assisting and remedying, such as when polluting has appearred in room air, use air purifier can pollution abatement degree to a certain extent, but and do not mean that and fundamentally can eliminate atmospheric pollution.
Above method is all the remedial measures after finishing, and most effective means is exactly the harm just fully taking into account formaldehyde before finishing in fact, selects environment-friendly materials as far as possible, accomplish to provide for a rainy day in fitment process.
