Abstract
The invention discloses a kind of purifying formaldehyde method, includes the following steps: that indoor formaldehyde scavenger is scattered in interior by (1), close the door window closed 4-7 days, wherein the dosage of the indoor formaldehyde scavenger is 15-30 grams/m；(2) windowing of opening the door is divulged information 1-3 days.The indoor formaldehyde scavenger is made of the raw material of following weight parts: 3~7 parts of bentonite, 1~1.5 part of tea polyphenols, and amino acid 1~3 part, 80~90 parts of adduct sodium sulphate-hydrogen peroxide-sodium chloride, 180 parts of deionized water, 1~5 part of lauryl glucosyl.A kind of method of purifying formaldehyde of the present invention, has health environment-friendly, can effectively decompose the harmful substances such as formaldehyde, the benzene in air for a long time, to achieve the effect that remove Indoor Air Formaldehyde.
Description
Technical field
The invention belongs to daily necessities technical fields, and in particular to a kind of purifying formaldehyde method.
Background technique
Formaldehyde is noxious material, median lethal dose (rat, oral) 800mg/kg, steam energy intense stimulus mucous membrane, tool
There is carcinogenicity, belong to high poisonous substance.It can be reacted with the ionic chloride in air generates carcinogen-dichloro formaldehyde ether.First
Aldehyde not only can make protein denaturation in conjunction with the amino in protein to cause the injury to human body, actually formaldehyde is to people
The injury of body be it is various, high-concentration formaldehyde is also toxic to nervous system, immune system, liver etc..Formaldehyde is to human body
Injury can also be through a variety of ways: formaldehyde can be absorbed through respiratory tract, suck high-concentration formaldehyde after, it may appear that respiratory tract it is serious
Stimulation and oedema, eye shouting pain, headache, can also occur bronchial asthma.Direct skin contact high-concentration formaldehyde, can cause dermatitis,
Color spot, necrosis.Its aqueous solution " formalin " can be absorbed through alimentary canal.
A small amount of formaldehyde is often sucked, slow poisoning can be caused, chronic respiratory disease, mucous membrane hyperemia, skin can be caused
The symptoms such as disease, allergic dermatitis angling and fragility, nail matrix finger tip pain are stimulated, or even cause nasopharyngeal carcinoma.For women, warp
Often suck a small amount of formaldehyde, in fact it could happen that feminine menstrual disorder, pregnant woman sucks for a long time may cause pregnancy syndrome, cause newborn
Constitution reduction, chromosome abnormality, ewborn infant deformity, in addition it is dead.Man sucks for a long time serious can lead to leukaemia, gas
Chest, fecundity missing, constitutional symptom have headache, out of strength, stomach is received poor, palpitaition, insomnia, weight loss and vegetative nervous disorder
Deng.The people of Long Term Contact formaldehyde can cause nasal cavity, oral cavity, nasopharynx, throat, skin and gastral cancer.
Formaldehyde is a kind of important Organic Ingredients, is mainly used for artificial synthesized adhesive, such as: phenolic resin processed, ureaformaldehyde tree
Rouge, synthetic fibers (such as synthesis vinylon-polyvinyl formal), leather industry, medicine, dyestuff.Various artificial board (planes
Card, density board, fiberboard, glued board etc.) in due to having used urea formaldehyde resin adhesive, thus formaldehyde can be contained.New-type family
The production of tool, the decoration laying of metope, ground, will use adhesive.All a large amount of places using adhesive, always have first
Aldehyde release.Material containing formaldehyde can deaerate, and be classified as a kind of human carcinogen likely by Environmental Protection Agency USA.
For above-mentioned formaldehyde pollution, formaldehyde scavenger product, usual according to physical absorption or chemisorption currently on the market
Processing mode eliminate removing residue formaldehyde, but can have following technological deficiency: using physical absorption, such as active carbon, bamboo charcoal,
Adsorbance is limited, and inconvenient for use, it is often necessary to replace, form secondary pollution；Using chemisorption, although processing formaldehyde effect
Fruit is good, but the toxicity of compound being added in scavenger is larger, not environmentally friendly enough, will cause environmental pollution after long-time service, and influence
Occupy indoor user health；The using effect of part commercial product will receive the limitation of application environment, in most formaldehyde scavengers
Containing titanium dioxide, containing titanium dioxide, careless acid dihydrazide etc., since titanium dioxide is ultraviolet light catalyst, in natural light or
Under no light condition, the removal effect of formaldehyde is extremely limited, and has application limitation.Therefore, how purifying indoor formaldehyde change is carried out
It obtains extremely important.
Summary of the invention
The purpose of the present invention is being directed to the deficiency of existing indoor formaldehyde minimizing technology, a kind of purifying formaldehyde method is provided.
A kind of method of purifying formaldehyde, includes the following steps:
(1) indoor formaldehyde scavenger is scattered in interior, is closed the door window closed 4-7 days, wherein described indoor
The dosage of formaldehyde scavenger is 15-30 grams/m；(2) windowing of opening the door is divulged information 1-3 days.
Further, the indoor formaldehyde scavenger is made of the raw material of following weight parts: 3~7 parts of bentonite, tea is more
1~1.5 part of phenol, amino acid 1~3 part, 80~90 parts of adduct sodium sulphate-hydrogen peroxide-sodium chloride, 180 parts of deionized water, ten
1~5 part of dialkyl group glucoside.
Further, the amino acid is the mixture of ASPARTIC ACID and L- homoserine, wherein L- asparagine
The mass ratio of acid and L- homoserine is 2.5:1-1:2.5.
Further, the amino acid be alanine, tryptophan, ASPARTIC ACID, histidine, lysine, glutamic acid,
One of methionine, proline, threonine, leucine, arginine, interior propylhomoserin, glycine and L- homoserine or its mixing
Object.
Further, the adduct sodium sulphate-hydrogen peroxide-sodium chloride is prepared using following methods: by chlorination
Sodium is added in hydrogenperoxide steam generator, adds anhydrous sodium sulfate, stirs, and decompression filters, vacuum drying.
Indoor formaldehyde scavenger of the invention is prepared using conventional method in that art, such as can be more by bentonite, tea
Phenol, amino acid, adduct sodium sulphate-hydrogen peroxide-sodium chloride, water and lauryl glucosyl mix according to the ratio, and stirring is equal
It is even to can be prepared by indoor formaldehyde scavenger of the invention.
A kind of method of purifying formaldehyde of the present invention, has health environment-friendly, can effectively remove the first in room air for a long time
Aldehyde.
Specific embodiment
For the predetermined purpose and technical means and efficacy that the present invention is further explained, with reference to embodiments to of the invention
Specific embodiment is described in detail.
The wherein preparation of adduct sodium sulphate-hydrogen peroxide-sodium chloride:
50 kilograms of sodium chloride are added in 200L35wt% hydrogenperoxide steam generator, are kept for 25 DEG C of temperature, under constant stirring,
60 kilograms of anhydrous sodium sulfates are slowly added to, constant temperature is stirred to react 30min.Decompression filters, vacuum drying.Obtain 68 kilograms of product sulphur
Sour sodium-hydrogen peroxide-sodium chloride adduct, wherein content of hydrogen peroxide 9.3wt%.
A kind of preparation of indoor formaldehyde scavenger: by 5 parts of bentonite, 1 part of tea polyphenols, 2 parts of amino acid, above-mentioned preparation institute
