Is there a relationship between the hours of closing doors and windows and the detected values in indoor air testing?

Of course, the detection value is related to the window closing time. Obviously, the longer the window is closed, the higher the detection result. Two national standards, 50325, 1 hour, 18883, 12 hour.

"The house has just been renovated for a month, and children need to hurry to move when they get married. The smell is still very strong. How much is in addition to formaldehyde here? " Jinan lives in the high-tech zone.

Ms. Zhang of China Railway Yidu International asked when calling for advice. There are not a few owners who call directly to ask questions like Ms. Zhang.

How much is Jinan in addition to formaldehyde? What harmful gases will be produced during decoration? Where do these harmful gases mainly exist? Nail removal

What is the process before and after aldehyde? So Jinan Shuangshi in addition to formaldehyde Company is one of the earliest and most experienced environmental protection companies established in Jinan, so I ask the above questions.

Answer the questions one by one.

1. The main harmful gases produced by new house decoration or adding new furniture are formaldehyde, benzene, TVOC, ammonia, toluene, xylene and even radioactivity.

Radon.

1, formaldehyde-Anxin floor used by many well-known real estate houses in China, found that formaldehyde exceeded the standard. I believed a lot after this incident was exposed.

People began to understand the pollution and harm of formaldehyde in decoration. Especially children and pregnant women, because of their weak constitution, are particularly sensitive to formaldehyde and are equally harmful.

It's even bigger. If you have been to hospital obstetrics, you have childhood leukemia, fetal failure, fetal malformation and infertility.

There are too many cases, which can be described as horror. Of course, this is caused by many reasons, but according to the survey, there are quite a few cases.

The reason is that the home has just been renovated. Formaldehyde is a highly toxic gas, which ranks in the forefront of the list of toxic gases in China.

2, formaldehyde mainly exists in:

A wall latex paint, the diluent contains formaldehyde. Now many big brands of latex paint have little or no taste, but because

Due to the large coating area of latex paint, the owner should pay attention to the formaldehyde constantly emitted inside.

B-composite flooring (laminate flooring, solid wood composite flooring), because pure solid wood flooring is easy to deform and difficult to maintain, is increasing.

Some people use composite floors. From the perspective of environmental protection, reinforced floors contain more formaldehyde than solid wood composite floors.

C-wardrobes, like other furniture, solid wood furniture is better than panel furniture from the perspective of environmental protection. The surface of solid wood furniture generally needs painting, and the oil on the surface

There will be formaldehyde and benzene in the paint. In order to ensure that the paint does not fall off, a lot of glue is needed, and the glue contains formaldehyde. Panel furniture is divided into: large core board (

Solid wood core plywood, double-sided sanding bonding. One of the disadvantages is that formaldehyde emission is generally high, because blockboards are produced in large quantities in the production process.

Using urea-formaldehyde adhesive, the formaldehyde emission is generally high, and the environmental protection standard is generally low, which is also the reason why most blockboards have pungent smell.

Particleboard is to cut all kinds of branches and buds, fast-growing wood, small diameter wood, sawdust and other things into pieces of certain specifications, dry them, and then glue them.

, hardener, waterproof agent, etc. A kind of artificial board which is pressed at a certain temperature and pressure. Because its cross section is similar to honeycomb, it is called wood shavings.

Board of directors; Fiberboard is called density board. Fiberboard is made of plant fiber as the main raw material through thermal grinding, sizing, paving, hot pressing and other processes.

Formulate working procedures. Multi-layer solid wood board Multi-layer solid wood board is based on criss-crossing multi-layer plywood, and the surface is made of high-quality solid wood veneer or craft wood.

Fabric is made by cold pressing, hot pressing, sanding and curing. A lot of adhesives will be used in the processing of these furniture plates.

The environmental protection index is relatively low, and panel furniture is also the main treatment object in in addition to formaldehyde.

D- formaldehyde is produced in the process of wallpaper manufacturing. In order to make the wallpaper stick to the wall better, it is necessary to use glue to produce formaldehyde.

Electronic doors and doorframes

Curtains, sofas, mattresses. Finally, these pollution sources are often overlooked, but they are also rich in formaldehyde.

The invisible killer in the room.

3. What are the symptoms in a room containing formaldehyde for a long time?

Everyone has different physique, sensitivity and symptoms. Bad indoor air first stimulates the respiratory tract, so the throat

Discomfort, dry throat, frequent coughing and sneezing are the most common symptoms, and many owners report cleaning their new homes before moving.

When you are born or do something 1 or 2 hours, you will feel dizzy, headache, even nausea and vomiting, and your resistance will decrease, especially among residents.

Easy to catch a cold. The plants in the room withered, and the fish in the fish tank could not live. In order to improve the indoor environment, some families planted a tree indoors.

Some plants, but if plants often wither, then indoor formaldehyde has exceeded the standard.

Second, the harm of formaldehyde to people is enormous. More and more people have a deeper understanding of indoor formaldehyde, and they will find a local one after renovation.

What is the process of in addition to formaldehyde Company (for example, Jinan Shuangshi Environmental Protection Technology Co., Ltd., the most professional unit in Jinan in addition to formaldehyde) and in addition to formaldehyde?

The first test (if it exceeds the standard)-comprehensive air purification (tailor-made purification scheme for different pollution sources and pollutants, sign

Sign a formal business contract and guarantee for life)-Second inspection (review)

3. How much does it cost to build a new house in in addition to formaldehyde (take Jinan in addition to formaldehyde as an example).

On the premise of ensuring the effect, the average square meter is 20-25 yuan, and regular professional companies will tailor the treatment measures according to different pollution sources and pollutants.

In the case, there is a warranty in the later period. If new furniture is added, it will be handled free of charge. Now the root of the chaos in Jinan market is many cleaning companies and property companies.

Even some individuals buy some products casually from the internet and start their business with simple equipment. You can judge the pollution source without professional testing.

Situation; Second, I am not engaged in the indoor environmental protection industry. I am not a professional. Sometimes I use what products, product dosage and construction technology according to my own feelings.

Over the years, the result is that the treatment effect is not good, and many owners have suffered greatly recently. Many owners have to spend money to find a professional company to purify, not only not.

Save money and spend more.
