Indoor formaldehyde detection
Source: Spectrum detection Author: Sales Department published on: 2015-12-06 11:12:00

formaldehyde It is a colorless gas with strong pungent odor. Soluble in water, alcohol and ether. Formaldehyde is gaseous at room temperature, usually in the form of aqueous solution. Soluble in water and ethanol, 35-40% formaldehyde aqueous solution is called formalin. Formaldehyde molecule Phenolic resin (bakelite) was obtained by condensation polymerization of aldehyde group. Formaldehyde is an important organic raw material, which is mainly used in plastic industry (such as phenolic resin, urea formaldehyde plastic calcium carbide), synthetic fiber (such as vinylon polyvinyl formal), leather industry, medicine, dyes, etc.

 Indoor formaldehyde detection

Formaldehyde removal, formaldehyde hazard, formaldehyde removal method:

Harm of formaldehyde removal by ventilation

The best way is ventilation, which is the most simple, economical and effective method. It's best to go through a summer, a heating season.

The harm of formaldehyde removal by green plant absorption method

Plants have a strong ability to absorb formaldehyde, such as cactus, Chlorophytum, reed, ivy, iron tree, chrysanthemum and so on.. Generally speaking, the effect of formaldehyde absorption by plants with large leaves and herbs is better, such as Chlorophytum, huweilan, etc.

Harm of formaldehyde removal by activated carbon adsorption

Activated carbon can be said to be the natural enemy of formaldehyde. Solid activated carbon has many pores and has strong adsorption and decomposition effect on formaldehyde and other harmful substances. The smaller the particle size of activated carbon, the better the adsorption effect.

Reducing the harm of formaldehyde by absorption of vegetables and fruits

You can put the pomelo peel, onion slices, pineapple pieces in the newly decorated room or cabinet, or fumigate the whole room with white vinegar.

Formaldehyde scavenger (formaldehyde scavenger, formaldehyde scavenger)

These chemicals are only useful for formaldehyde. The effect is obvious. But it's gone after the reaction. Wipe off the products in time.

Ultraviolet lamp reduces the harm of formaldehyde

Sterilization effect is still good. But the living things have to be evacuated. I don't recommend using these things at home.

Effect of negative oxygen ions on formaldehyde

Negative oxygen ion is good for removing smoke, but it has no effect on formaldehyde.

Effect of photocatalyst on formaldehyde

Photocatalyst is a kind of nano scale metal oxide material (titanium dioxide is commonly used). It is coated on the surface of the substrate and produces strong catalytic degradation function under the action of light: it can effectively degrade toxic and harmful gases in the air; it can effectively kill a variety of bacteria, and can decompose and harmless the toxins released by bacteria or fungi; at the same time, it also has deodorization, anti pollution, etc Function.

advantage: Safe, no side effects, comprehensive treatment, prevention and control, efficient.

Disadvantages: Need light source (high quality photocatalyst, it can work under ordinary fluorescent lamp)

The harm of formaldehyde was revealed

Stimulating effect: The main harm of formaldehyde is the irritation to skin and mucous membrane. Formaldehyde is the protoplasm toxic substance, which can combine with high protein. When inhaled with high concentration, serious irritation and edema of respiratory tract, eye irritation and headache will occur.

Sensitization effect: Direct skin contact with formaldehyde can cause allergic dermatitis, color spots and necrosis. Inhalation of high concentration formaldehyde can induce bronchial asthma.

Mutagenic effect: High concentration formaldehyde is also a genotoxic substance. Experimental animals in the laboratory inhalation of high concentration, can cause nasopharyngeal tumor.

Prominent manifestations: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, throat pain, stomach anorexia, palpitation and insomnia, weight loss, memory loss and autonomic nerve disorder, etc. long term inhalation of pregnant women may lead to fetal malformation or even death, and long-term inhalation of men can lead to male sperm malformation and death.

Formaldehyde hiding place:

1. Plywood, blockboard, MDF and particleboard for interior decoration;

2. Wood based panel furniture, fabric furniture, kitchen cabinet, etc;

3. Unqualified white latex and coating, etc;

4. Interior decorative textiles, including bedding, wall cloth, wallpaper, carpet and curtain, etc;

5. The harm of formaldehyde in the new car must not be ignored. All kinds of accessories and materials of the new car itself, such as interior plastic, leather cover, etc. Automobile interior structure is mainly composed of leather, fiber and various engineering plastics, and these materials need to use formaldehyde, benzene and other harmful substances in production.

matters needing attention:

Do an indoor test after the decoration.

After new construction, more windows must be opened for ventilation.

Put more flowers and plants that don't bloom often, such as Clivia, cactus and aloe.

Don't rush to check in, wait for the air quality to be qualified.

Advocate simple decoration style and select high-quality decoration materials, which can help you reduce the harm of toxic gas and also let you live in a new home as soon as possible. Wish you a happy life ~!
