The renovated house has newly painted walls, new beds, new doors, and how heavy is formaldehyde

It can only be clear after testing by a professional institution.

There are many ways to deal with indoor formaldehyde:

1. Ventilation is aimed at formaldehyde in indoor air.

2. Activated carbon targets lower levels of formaldehyde.

3。Compound air pollution purification liquid purifies a variety of toxic and harmful gases at the same time, and professional products are used to remove them.

4。Professional company decoration pollution control has the best effect on the professional treatment of pollution sources.

This is incalculable, oh, the formaldehyde content is different depending on the material. You can find a professional formaldehyde cleaning company to test and clean up. It is also possible to open more windows for ventilation.

Depending on what material you use, the formaldehyde content of the paint is higher, the beds and doors are less, and the ventilation can be moved in for a month.

Houses like this that exceed the formaldehyde standard or have more formaldehyde must be treated. Especially for furniture panels.

In many cases, it is safer to spray liquid live ore, that is, nano aldehyde removal enzyme.

It can also form a protective film to isolate harmful substances for a long time.

Indoor plants have a certain effect on the absorption of formaldehyde, but they are by no means a drug machine, they do not have so much energy, there is no basis for saying how much formaldehyde can be absorbed every day, and the statement is even more unscientific. In order to remove the pollution from the newly renovated house as soon as possible, opening the windows and ventilation is the most effective method, and any other means can only be an auxiliary means, and plants are no exception. Of course, if you want to remove formaldehyde as soon as possible, you must use auxiliary means, and you can use herb Diarin to use herbs at the same time to ventilate and plant spider plants.

Use some photocatalyst for Huankang nano-aldehyde enzyme. Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nano-scale titanium dioxide, which is coated on the surface of the substrate and produces a strong catalytic degradation function under the action of ultraviolet light: it can effectively degrade toxic and harmful gases in the air.

Technical principle of photocatalytic decomposition of decoration pollution by negative ion photocatalyst.

Anion photocatalyst (nano titanium dioxide) is a composite word of light + catalyst (catalyst). Negative ion photocatalyst is an upgraded product of photocatalyst, and it is also a catalyst. A catalyst is a substance that is used to reduce the energy required for a chemical reaction and to speed up the chemical reaction, but it does not change due to the chemical reaction.

Anion photocatalyst (no special requirements for reaction conditions after treatment of decoration pollution, i.e., ventilation and light) as the name suggests, is to use the energy of light as the chemical reaction energy**, accelerate the redox reaction, so that the oxygen and water molecules adsorbed on the surface are excited into highly active hydrogen and oxygen radicals and negative oxygen ions, these hydrogen and oxygen free and negative oxygen ion groups with strong oxidation power can decompose almost all organic substances and some inorganic substances that are harmful to the human body or the environment. It can be rapidly oxidized and decomposed into stable and harmless substances to achieve the function of purifying the air.

Under visible light irradiation, the negative ion photocatalyst can produce an electron (E) transition, which reacts with oxygen in the air to produce O2 (negative oxygen ion). The holes (H+) left behind by the electron transition react with water in the air to form highly reactive ·ooh or ·oh (hydroxide radicals). Because the generated free radicals have strong oxidation and decomposition ability, they can destroy C C bonds, C N bonds, C O bonds, H O bonds, and N H bonds in organic matter (the chemical formula of formaldehyde is CH2O, and the chemical formula of benzene is C6H6), so it has the ability to efficiently decompose organic matter.

And decompose them into water and carbon dioxide and harmless substances, while the photocatalyst itself does not consume after participating in the reaction, so it has a long-term effect.

Go to the flower market and buy a green pineapple or use a Philips air purifier.

Ventilation, activated carbon, and plants can evacuate and reduce gaseous polluting organic matter such as formaldehyde, benzene, ammonia, and TVOC, but cannot be removed.

At present, the corporate governance formaldehyde has.

Photocatalyst: A method in which formaldehyde can react with titanium oxide under strong ultraviolet conditions, thereby destroying the molecular structure of formaldehyde. However, the activity of titanium oxide is low, and the ultraviolet rays in ordinary sunlight cannot make it react, so it has caused the family and company that have done formaldehyde treatment, and after the treatment, after staying for a period of time, they feel headaches, dry mouth (drinking water is not cured) and other physical abnormalities, and formaldehyde is once again recovering and flooding the room.

Air purifier: Some people say that air purifiers can remove formaldehyde, but in fact, air purifiers cannot essentially treat gaseous pollutants such as formaldehyde and benzene, but mainly treat particulate matter and floating matter (fungi and microorganisms attached to particulate matter).

Chemical reagent method: Our company can carry out the detection of indoor and other recovered organic matter free of charge. Engaged in professional treatment of indoor formaldehyde, benzene, ammonia, TVOC and other restorative gaseous polluting organic compounds.

Directly from the source of the permeable formaldehyde and other recovered organic matter to capture and control, the generation of crystal particles, no harm to the body, report the microelectric king 132, 4023, a handful.

The safest way is to find a professional company to test governance. It's good to be fresh, you can check it on the Internet.

It is very likely that the key depends on the material you choose, it is recommended that you ventilate for a period of time, and you can do a formaldehyde test.

Probably, I will teach you a little trick, put the grapefruit peel in the corner and close the window, and then open the window again two days later, and the formaldehyde smell is gone.

There is a way to quickly remove formaldehyde in new houses!

After the decoration of the new house, I want to move in quickly, but I am afraid that the indoor formaldehyde pollution will exceed the standard. This is the biggest headache for most people. Don't worry, Jinan Mutong Environmental Protection Technology teaches you how to quickly remove formaldehyde from your new house.

Rest assured.

Formaldehyde is usually divided into short-term formaldehyde pollution sources and long-term formaldehyde pollution sources. Targeted treatment should be given to different formaldehyde release sources in order to quickly remove formaldehyde pollution from new houses.

Short-term sources of formaldehyde emissions in new homes usually come from curtains, wallpaper, paints, coatings, etc. There are several ways to deal with short-term formaldehyde emission sources:

1. Photocatalyst.

The catalyst of photocatalyst is to catalyze the decomposition of formaldehyde released in the air under the action of light, and decompose it into harmless substances such as carbon dioxide and water.

2. Green plants. Green plants will decompose a certain amount of formaldehyde in the air through their own absorption and decomposition.

3. Activated carbon adsorption.

Activated carbon itself has pores, and these pores are used to absorb pollutants in the space, and the adsorption capacity is better at 10 degrees Celsius. The carbon ladle needs to be replaced regularly, otherwise once saturated, the charcoal bag itself will become a source of formaldehyde release. Secondary pollution will be generated.

4. Ventilation. Ventilation is a common method after the renovation of a new house, and it is the easiest and most affordable method. For short-term formaldehyde release sources, most of them will be released after about half a year.

The above methods are all aimed at short-term formaldehyde emission sources, and they have little effect on long-term formaldehyde emission sources.

There are other ways to target long-term formaldehyde emission sources.

Adhesives will be used in new house decoration and furniture decoration, and the adhesive used is urea-formaldehyde resin glue, which decomposes when exposed to moisture and heat, and the release life ranges from 3 to 15 years. If you want to get rid of long-term formaldehyde, you can do it in three steps:

1. Pollution source detection, detect formaldehyde release sources, and understand the degree of pollution (formaldehyde self-test box can be used).

2. Formaldehyde treatment, select long-term effective products, and control formaldehyde pollution (Mutong strong aldehyde remover).

3: Effect monitoring, detection of treatment effect (formaldehyde self-test box).

The first method is to use formaldehyde detectors, such as "six-in-one" and "eight-in-one", which are widely used in the market to detect formaldehyde. The principle is the same as that of the exam paper. On-site sampling, reading data through field instruments, and printing simple reports.

This kind of detection is relatively cheap, but the accuracy of the data is not high, so we can only make a preliminary judgment. In addition, this method cannot detect benzene congeners and TVOCs. If someone says it can be detected, it's also manual data.

Many small companies in the market use this method to detect if indoor air exceeds the standard.

The second is that the home tester is only responsible for sampling air samples, and then sending the collected samples to a professional laboratory for analysis and calculation, and can issue a report within 2-3 working days. The equipment used in such test stations is relatively expensive, ranging from hundreds of thousands to several millions. Therefore, there are very few such experimental equipment.

The most important feature of this type of probing is that the probe data is very accurate. In general, customer testing is done to get the most accurate data. If the detection method is not scientific, resulting in inaccurate data, it is a waste of money and misleading to customers.

Third, there must be a third-party testing agency with independent CMA testing qualifications to conduct testing and issue CMA testing reports.

The data obtained from the test is as accurate as the data from the second test, and the report issued has the force of law and can be used to deal with housing purchase disputes or engineering inspections. The requirements for laboratories to be qualified for CMA testing are very strict, and there are not many institutions in the industry that have CMA testing qualifications. The test takes a relatively long time to generate a report, often more than a week, and is the most expensive of the three.

Formaldehyde exceeding the standard is very harmful, formaldehyde will enter the body through the respiratory tract, **, etc., which will cause serious damage to the human nervous system, respiratory system, hematopoietic system, etc., increase the probability of leukemia, and cause greater harm to the human body. If you want to truly treat indoor formaldehyde, it is recommended to use professional formaldehyde removal products for treatment.

Indoor formaldehyde detection and retest method: system.

1. Electrochemical sensor method: electronic induction equipment detection, DU This is the simplest zhi method, DAO is very convenient to use in our family, but we must pay attention to quality problems when buying this kind of instrument, and the indoor formaldehyde content value detected by this kind of instrument in many markets is not accurate;

2. Gas chromatography;

3. The detection of indoor formaldehyde content by AHMT spectrophotometry is a bit complicated. First of all, it is necessary to ensure that the indoor temperature is about 28 degrees, and it is very troublesome to do experiments with special solution preparation and precise steps. But I'll also talk about the basic steps:

1. Pipette 5ml of water into a 10ml test tube; 2. Prepare standard series according to the proportion; 3. Add 2ml of disodium ethylenediaminetetraacetic acid, sodium hydroxide solution and 2ml of AHMT solution to the water sample and the standard series we prepared above, stir and store evenly for 20min, add potassium periodate, store for 5 minutes, and measure the absorbance with pure water as a reference. This approach is complex. Moreover, it is difficult to grasp the dose, and the requirements for professional chemical experiments are very high, which is not commonly used in our usual indoor formaldehyde detection;

4. Phenol reagent spectrophotometry: It is based on the chemical reaction between formaldehyde and phenol reagent in the air, and the color on the test strip is used as a reference, which is a bit similar to the pH experiment done in our junior high school chemistry class.

There are several ways to detect formaldehyde: 62616964757a686964616fe4b893e5b19e31333365663431

1. Formaldehyde self-test box.

2. Formaldehyde testing institution.

3. Portable formaldehyde detector.

If formaldehyde is found to exceed the standard after testing, it is necessary to consider removing formaldehyde at this time.

There are many ways to remove formaldehyde, and the commonly used ones are:

1. Open window ventilation: open window ventilation mainly uses the circulating air to discharge free formaldehyde, which is the most economical and practical way, but it cannot pollute the source of formaldehyde.

2. Green plants: There is an absorption of formaldehyde by green plants, but because the leaves of plants are relatively small and a passive reaction, even if they can be absorbed, the amount is very small.

3. Activated carbon: Activated carbon is the principle of adsorption, which will be saturated after adsorption for a period of time, and formaldehyde will be released again after saturation, which is easy to cause secondary pollution, so it needs to be replaced regularly.

4. Air purifier: The principle of formaldehyde removal in the air purifier is the same as that of activated carbon, and the air purifier uses the activated carbon filter inside to adsorption, and it will be released again after the adsorption is full, causing secondary pollution, which needs to be replaced regularly.

5. Formaldehyde removal spray (photocatalyst, biological enzyme, etc.): Formaldehyde removal spray is mainly to decompose formaldehyde, some sellers will exaggerate the effect and say that it can seal formaldehyde and prevent the formaldehyde from being released at the source, which is actually unachievable, and some say that it can penetrate into the plate and decompose the formaldehyde inside, which is an exaggeration. Formaldehyde removal agent spray is mainly free formaldehyde released by decomposition.

6. Formaldehyde treatment company: The level of formaldehyde treatment company is uneven, and some of them are only sprayed with chemicals to remove formaldehyde. Regular formaldehyde removal companies will first use high-temperature fumigation liquid to quickly release the formaldehyde from the source of pollution, and then spray with formaldehyde removal agents to decompose the released free formaldehyde.

This is not easy to operate, after all, if you want to test this aspect, you can only ask a special department to apply.
