Abstract
The present invention discloses an adsorption-absorption reaction type formaldehyde removing agent which is composed of an adsorbing-absorbing agent and reactants of sodium sulfite and ammonium salts, or sodium sulfite and hydroxylamine hydrochloride, wherein the adsorbing-absorbing agent can be activated carbon, aluminum oxide, kieselguhr, polyamide, water, etc. and has two states, solid and liquid. The present invention has the removing mechanism of formaldehyde that formaldehyde in air is adsorbed and absorbed by the adsorbing-absorbing agent; the adsorbed-absorbed formaldehyde rapidly reacts with the reactants in the removing agent to prepare acid, alkali and corresponding products; the acid and the alkali are neutralized to prepare salts and water, and the formaldehyde is completely converted into nontoxic tasteless new substances without secondary pollution. The formaldehyde removing agent can be directly put in indoors or sprays the indoors, and has the characteristics of obvious effect, economical and practical operation, no harm to a human body, no secondary pollution, etc.
Description
Affiliated field
The present invention relates to a kind of formaldehyde eliminating agent.
Background technology
Along with the raising of people's living standard, people have been universal phenomena to the finishing of room and workplace.Yet (as artificial board, coating, paint etc.) contain volatile formaldehyde more in the finishing material that uses, can be behind finishing discharge gradually from finishing material in for a long time and cause indoor free formaldehyde content severe overweight, room air is subjected to severe contamination.The medical experiment result shows that it is 14.1ppM that mouse is exposed to concentration of formaldehyde for a long time
-5.6ppm air in can bring out rhinocarcinoma, the European Community and Environmental Protection Agency (EPA) also formaldehyde is classified as may be carcinogenic material.Although do not find out the definite relation between certain canceration and formaldehyde at present as yet, but national governments have all formulated the rules of concentration of formaldehyde in the relevant qualification environment, and regulation formaldehyde in indoor air concentration is the highest in (GB18580-2001) must not surpass 0.08mg/m for China's national standard " formaldehyde sanitary standard in the indoor air "
3According at present new finishing dwelling house room air Investigation on Formaldehyde Pollution being shown that the indoor concentration of formaldehyde of newly-decorated dwelling house is 6.65 times of outdoor concentration of formaldehyde, exceed standard 5.15 times.Because formaldehyde gas has strong impulse to people's eyes and respiratory mucosa, and live in for a long time can be produced people's nervous system in the environment of formaldehyde severe contamination and have a strong impact on, cause immune level and some dysfunction of organ, cause headache, nauseating, tired, drowsiness etc.Existing solution mainly is to add the auxiliary agent of formaldehyde eliminating agent and so on or spray formaldehyde eliminating agent in building board production process on the plate face, reaches the purpose that reduces free formaldehyde.Facts have proved that some can reduce the resistance to water of wood-based plate to adopt these methods, some modifier price is more expensive, will certainly improve the cost of product, and addition is too much, can influence the curing of resin, reduces the bonding strength of wood-based plate.Therefore it is thorough that formaldehyde is eliminated in development, and harmless, and the indoor formaldehyde remover of non-secondary pollution has important practical significance again.
Summary of the invention
Purpose of the present invention is exactly to pollute at the formaldehyde in the room air to develop a kind of product one absorption absorption reaction type formaldehyde eliminating agent that can fundamentally thoroughly eliminate formaldehyde, can directly place indoor or spray indoor, effect is obvious, and harmless, does not produce secondary pollution.
This absorption absorption reaction type formaldehyde eliminating agent is to be made by the component of following ratio of quality and the number of copies:
1 part in adsorbent
Sodium sulfite 0.5-1.5 part
Ammonium salt 0.2-1 part.
Also make by the component of following ratio of quality and the number of copies:
1 part in adsorbent
Sodium sulfite 0.5-1.5 part
Hydroxylamine hydrochloride 0.2-1 part.
Add adsorbent and be for the absorption of the formaldehyde in the room air, this class adsorbent can be selected active carbon or aluminium oxide or diatomite or polyamide or molecular sieve or silica gel etc. for use; Ammonium salt can be selected ammonium sulfate or ammonium chloride or ammonium nitrate or ammonium carbonate or ammonium acetate or ammonium oxalate or ammonium hydrogen phosphate etc. for use.
A kind of absorption absorption reaction type formaldehyde eliminating agent, it is to be made by the component of following ratio of quality and the number of copies:
100 parts in water
Sodium sulfite 2-20 part
Hydroxylamine hydrochloride 1-10 part.
Water here uses as absorbent, indoor formaldehyde can be absorbed.
Formaldehyde eliminating agent of the present invention from this is divided into solid absorption type and two kinds of forms of liquid absorption-type, but be that solid type or liquid-type all are at first to utilize the absorption absorbent that the absorption of the formaldehyde in the room air is absorbed, the formaldehyde that is adsorbed absorption rapidly and the reactant in the formaldehyde eliminating agent react, generate bronsted lowry acids and bases bronsted lowry and corresponding product, acid-base neutralization generates salt and water, finally makes formaldehyde be converted into novel substance nontoxic, tasteless, harmless, non-secondary pollution.Chemical equation is as follows:
It is as follows that this formaldehyde eliminating agent PARA FORMALDEHYDE PRILLS(91,95) is eliminated the effect experiment:
The elimination effect of solid absorption response type remover PARA FORMALDEHYDE PRILLS(91,95) is got two closed containers that volume is identical, two culture dishes that fill the formalin of same concentrations and equal volume are placed two containers respectively, put into the solid type formaldehyde eliminating agent in one of them container, another is not put.In the identical time, measure the concentration of formaldehyde in the gas phase of two containers then respectively, the results are shown in Table 1.
Effect experimental result (the mg/m of table 1 solid type formaldehyde eliminating agent
