Abstract

The invention provides a kind of formaldehyde and close administering method, step is that source of pollution surface is first used clear water wiped clean by (1), spraying the first layer film, air seasoning 4h; (2) second layer film is sprayed, dry; Remove second layer film, repeat above step.Governance process of the present invention is simple to operate, and without any peculiar smell, membrane structure is tight, transparent, has no adverse effects to action face, achieves and has object, permanent removal formaldehyde for source of pollution, purify air.

Description

A kind of formaldehyde closes administering method

Technical field

The invention belongs to air purification field, relate to the improvement in Form aldehyde release source, especially a kind of close and the administering method of decomposing formaldehyde.

Background technology

Formaldehyde is a kind of colourless gas having intense stimulus smell, has comparatively high toxicity, and being defined as carcinogenic and teratogenecity material by the World Health Organization, is generally acknowledged allergen, is also one of potential strong mutagen.Decorations and making furniture will use artificial board, paint, coating, wallpaper etc., all contain sizing agent in these materials.On market, sizing agent has a variety of, as: urea-formaldehyde resin, melamine-formaldehyde, amido formaldehyde resin, resol etc., all contain formaldehyde.In the process of synthesis, some formaldehyde does not have complete reaction to fall, have residual, heat and wet will discharge formaldehyde, be dispersed in air, cause formaldehyde, its release period reaches 3 ~ 15 years, healthy to people of long-term effect, therefore, decorating and renovating material and new furniture are one of important sources causing formaldehyde in indoor air to pollute.

At present, the improvement carbaldehyde Method of indoor pollution mainly contains: physisorphtion, air purifier, air freshener, oxidation style etc.

Physisorphtion uses simple, but belongs to passive adsorption, adsorb saturated after, also very easily produce secondary pollution;

Air purifier generally can be divided into the combination of two or more form of mechanical type, electrostatic, negative oxygen ion formula, physical adsorption formula, chemisorption formula or front several form, and the removal principle of PARA FORMALDEHYDE PRILLS(91,95) is relevant to cleaner institute preferred form of this.Except PARA FORMALDEHYDE PRILLS(91,95) removal effect has limitation, take up room in addition large, the problems such as power consumption is high;

Air freshener just utilizes fragrance to hide formaldehyde peculiar smell, and sense organ is given people good environment, actual is the method for curing the symptoms, not the disease;

Oxidation style advantage has remove effect preferably to distributing aerial formaldehyde, and in order to prevent causing corrosion to contactant, working concentration is unsuitable excessive, and the removal chance like this for Form aldehyde release source just reduces a lot;

Above method all can to a certain degree removed or hide formaldehyde free in settle air, but release period is reached to the Form aldehyde release source of 3 ~ 15 years, formaldehyde in simple removal air or closed methanal, can't reach the basic demand for the treatment of air indoor formaldehyde.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art part, a kind of formaldehyde is provided to close administering method, the method will remove formaldehyde functional materials and closed material organically combines use, be painted on source of pollution surface, form double-layer films, realize administering formaldehyde from root, stop it endlessly toward air release formaldehyde, harm humans health.

A kind of formaldehyde closes administering method, and step is:

(1) source of pollution surface is first used clear water wiped clean, spraying the first layer film, air seasoning 4h;

(2) second layer film is sprayed, dry; Remove second layer film, repeat above step.

And constituent and the weight thereof of described the first layer film are respectively:

The per-cent sum of above-mentioned each component is 100%.

And constituent and the weight thereof of described second layer film are respectively:

Advantage of the present invention and positively effect are:

1, present method is at source of pollution surface spraying double-layer films, realizes improvement, closed methanal dual-use function.

2, present method is at Form aldehyde release source decomposing formaldehyde, prevents formaldehyde emission in air.

3, the film that present method is made has removing property, according to pollution level, realizes repeatedly spraying improvement, has no effect to surface in contact.

Embodiment

Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.

A kind of formaldehyde closes administering method, and step is:

(1) source of pollution surface is first used clear water wiped clean, spraying the first layer film, air seasoning 4h; The first layer membrane structure is closely transparent, and containing removing formaldehyde effective constituent Textone, effect is direct Formaldehyde Exposed and is decomposed.

(2) second layer film is sprayed, dry; If pollute comparatively serious, after improvement for some time, second layer film can be removed, repeats above step.The effect of the second tunic is the action time of effective constituent PARA FORMALDEHYDE PRILLS(91,95) in prolongation first tunic, simultaneously increasing action surface gloss.

Constituent and the weight thereof of the first layer film are respectively (for 1000g):

Constituent and the weight thereof of second layer film are respectively (for 1000g):

The Main Function principle of double-layer films is respectively:

Spray the first tunic, directly can act on Form aldehyde release source, Formaldehyde decomposition is become harmless product by the Textone in film; The polyvinyl alcohol that second tunic comprises, film forming is fine and close, and stopping property is good, plays sealing process, make Textone and formaldehyde have the enough reaction times to the Textone in the first tunic, improves and removes formaldehyde efficiency.

Example of the present invention:

Administer the desk newly purchased, desk material is artificial board, and after tested, this artificial board every square meter burst size of methanal every day is 100mg, severe overweight.First desk is taken apart by plate during improvement, all carefully spray two membranes in every one side of plate.The first layer film plays a kind of effect of decomposing formaldehyde, and air seasoning 4h, observes thin-film transparent, has no effect to contact surface; Second layer thin film coatings is at the first layer film surface, and air seasoning, observes surface good, and its effect is the effective constituent (such as Textone etc.) in closed first tunic, makes Textone and formaldehyde have the enough reaction times, improves and removes formaldehyde efficiency.Adopt spectrophotometer method test formaldehyde content, front and back data are administered in contrast, and after administering, formaldehyde obviously reduces, and is up to state standards.

Claims (1)

1. formaldehyde closes an administering method, it is characterized in that: step is:

(1) source of pollution surface is first used clear water wiped clean, spraying the first layer film, air seasoning 4h;

(2) spray second layer film, dry; If pollute comparatively serious, remove second layer film, repeating step (2);

Constituent and the weight thereof of described the first layer film are respectively:

The per-cent sum of above-mentioned each component is 100%;
