Where does formaldehyde come from in decoration, and where does formaldehyde come from in decoration

1. Laminate flooring.

In the process of processing composite flooring, formaldehyde needs to be used or formaldehyde is produced, and when the floor is pasted, it also needs to be fixed with adhesive with strong adhesion, so there is more formaldehyde emitted.

3. Door. The door needs to be painted, and many of them are processed by artificial wood, and a lot of formaldehyde is used in the processing process, so the door will also emit formaldehyde.

4. Wardrobe cabinets and other furniture.

Wardrobes, cabinets, etc., most of them need to be painted with color and more paint. In order to ensure that the paint does not peel off, a lot of glue is also used, so wardrobes, cabinets, etc. will also emit formaldehyde. In addition, the furniture made of solid wood emits less formaldehyde than the furniture of synthetic wood, because many artificial wood needs to use formaldehyde in the processing process, so the formaldehyde content is far greater than that of solid wood.

Solid wood furniture will be more environmentally friendly.

5. Wallpaper. Formaldehyde is produced in the manufacturing process of wallpaper. In order for the wallpaper to adhere better to the wall, it is also necessary to use glue and the like to produce formaldehyde.

Decoration involves all materials, auxiliary materials, main materials, as well as home, soft decoration, lamps, all kinds of will be included.

Formaldehyde in decoration is mainly used in furniture and floors and walls.

1. This kind of glue can make all wood residue, shredded paper, etc. into decorative building materials, and various sample materials such as particleboard, large core board, high-density board, and Aosong board commonly used in interior decoration are bonded with resin glue, so if the decoration carpenter at home is bigger, the larger the board used, the greater the probability of indoor formaldehyde, and the wooden floor inevitably belongs to this rank.

2. Part of the fabric, this kind of resin glue is also widely used in curtain fabrics, mattresses, blankets and other fabrics, because the resin glue made of formaldehyde can improve the wrinkle resistance of the cloth, fire performance, etc. Therefore, the corresponding indoor formaldehyde additives will also be added in the fabric processing, so this kind of items are with indoor formaldehyde.

3. Construction auxiliary materials, in the engineering decoration, the usual decoration company paints the so-called wall and ground solid on the wall and ground after entering the site, and this wall solid ground solid has formaldehyde components, including foam glue and structural glue added when installing window and door openings. The latex paint used in the construction of wall engineering is also an indoor formaldehyde additive, because the indoor formaldehyde additive has a certain moisture-proof and fireproof safety effect.

Decoration formaldehyde**.

1. Interior decoration of wood-based panels such as plywood, blockboard, MDF and planboard. Since the current production of decorative board adhesives is mainly urethral formaldehyde resin, the remaining and non-particulate formaldehyde will be released gradually. In the surrounding environment, it is the main body of formaldehyde in indoor air.

Furniture made of wood-based panels. In pursuit of high profits, some manufacturers use unsuitable panels and low-quality glue when using clipboard materials. As a result, the customer buys it home, which is equivalent to buying a small waste discharge station.

2。Other decorative materials containing formaldehyde can be discharged into the outside world, such as wallpaper, wallpaper, chemical fiber carpet, foam, paint, etc.

3。Some substances that release formaldehyde after combustion, such as cigarettes and some organic substances, are related to the following four factors.

1. Indoor temperature

2. Indoor relative humidity.

3. Indoor material filling degree (i.e., the surface area of formaldehyde released per cubic meter of indoor space) 4. Indoor ventilation (i.e., indoor airflow). High temperature, high humidity, negative pressure, and high load conditions all increase the emission intensity. The measurement results show that under certain conditions.

The concentration of formaldehyde in the air in a small living environment can be higher than the standard allowable level, and the release time is longer. Research from Yokohama National University in Japan shows that the indoor formaldehyde release period is 3-15 years.

Formaldehyde in decoration is mainly **in**? Man-made panels.

Formaldehyde is one of the components of adhesives, and adhesives are used in the processing of composite flooring, plywood, man-made panel furniture, etc., so the board is an important reason for excessive indoor formaldehyde.

2.wall coverings.

Improper selection of wall building materials such as paint, latex paint, and wallpaper will also cause the indoor formaldehyde content to exceed the standard, and the "zero formaldehyde products" claimed by some paint merchants on the market do not actually exist.

3.Home textiles.

Not only home building materials, but also newly bought curtains, carpets, fabric sofas, bed sheets, etc., will have an unpleasant smell, and there will also be formaldehyde. This is because in the process of textile printing and dyeing and finishing, the penetration of dyes is poor, and it is not easy to print and dye color dyes onto fabrics in an instant, and the only way is to add more binders containing formaldehyde!

If you say paint, refers to gypsum powder, then you can be very responsible to tell you that it does not contain formaldehyde, but if some glue is mixed into the paint, then the glue may contain formaldehyde, and formaldehyde is not produced in the decoration process, but in the decoration plate, which can not be confused, formaldehyde is mainly volatilized from the decoration board, and some of the chemical components used in the board are more, so the formaldehyde produced will last longer.

The content of formaldehyde has a lot to do with the decoration board, the glue used, the door, the cabinet, most of the board is a composite board, the use of glue to bond the wood sheet and the wood together, and this kind of board more or less has some formaldehyde. The volatilization rate of formaldehyde has a great relationship with the indoor temperature, the high temperature, the fast volatilization of formaldehyde, the low temperature, the slow volatilization of formaldehyde, and the speed of formaldehyde diffusion has a great relationship with the indoor ventilation. If you want to talk about the main ** of formaldehyde, the main thing is to conform to the template, and more than 50% of formaldehyde is produced by it.

And formaldehyde is a continuous volatilization process, many owners will be vacant for 1 3 months after the renovation of the house, during which they are often ventilated, the purpose is to let the continuous formaldehyde can be discharged from the room. In addition to the formaldehyde content in the board, that is, the furniture, like some special glues, wooden doors, paints, etc., also contain a certain amount of formaldehyde, but because of the different categories, the formaldehyde content is low. Moreover, there are some home decoration sewing agents used, and formaldehyde may also exist in this thing.

However, it is certain that if you say that the paint is gypsum powder, then it does not contain formaldehyde, because the paint is too cheap, and its manufacturing process is not as complicated as imagined, if you add chemical components containing formaldehyde, it has no other effect except harming people, and even increases the cost because of this, but it is said that some solid wall glue seems to contain a certain amount of formaldehyde, but so far I have not found that anyone's paint contains formaldehyde.

1. First of all, formaldehyde in new houses is mainly used in various furniture.

Buying furniture for new house decoration is essential, and many girls are still enjoying this happiness. What you don't know, most of these wardrobes, cabinets, shoe cabinets and even sofas and beds are made of man-made panels. More than 90% of China's wood-based panels are produced with urea-formaldehyde resin glue, one of its characteristics is that it will decompose when damp, and the process of releasing free formaldehyde can last for 3 15 years.

More than 80% of the formaldehyde pollution in the newly renovated new home is due to the formaldehyde release from wood-based panels. Formaldehyde will still exist for more than one or two years.

2. Composite flooring is also a formaldehyde release that cannot be ignored.

Nowadays, most young people who decorate their homes will use laminate flooring, because the beauty is not expensive. There are two kinds of laminate flooring: laminate flooring and solid wood flooring, both of which artificially change the natural structure of the flooring material, but what you don't know is that the composite flooring is also made of man-made panels, so the release of formaldehyde cannot be avoided. The wear-resistant layer on the surface of the laminate flooring and the PVC balance layer on the back allow formaldehyde to only be released from both ends, so the release amount is relatively small.

However, the surface of the parquet is painted, and the back is not closed, so the formaldehyde emission is relatively large, especially in summer. It is recommended that you remove formaldehyde from the back before decorating and laying the floor. But if you really don't notice this problem, you must pay attention to it later.

3. Curtains and wallpaper are the most likely to produce secondary pollution.

The curtains of the new home are newly purchased, and there are your favorite ones on the walls, and some of them are pasted with good-looking wallpapers, as well as various fabrics and textiles at home, which is really a new home and a new atmosphere. They also use adhesives in their production, but the formaldehyde release cycle is relatively short, almost released after half a year. The key is that the formaldehyde released by furniture and floors in the free state will be absorbed by curtains, wallpapers, and fabrics.

Even if the formaldehyde concentration decreases after the ventilation test in your home, the adsorbed formaldehyde will still be released again after closing the doors and windows, which is secondary pollution. If you find that the formaldehyde at home exceeds the standard, you should carry out Changsha formaldehyde treatment in time to protect the health of your family.

Contains pungent and acidic formaldehyde, mainly in artificial wood panels, from interior decoration and decoration materials. Man-made panels such as plywood, blockboard, and particleboard for medium-density fiberboard for interior decoration are the main body that forms formaldehyde in indoor air. Other types of decorative materials that contain formaldehyde and may be emitted to the outside world, such as wall coverings, wall chemical fibers in carpets, styrofoam, paints and coatings, etc.

Formaldehyde is more abundant: wardrobes (made of solid wood particle board should be the most), doors, floors, furniture, etc., because the surface layer is painted, so there is also a certain amount of formaldehyde.

Tips for removing formaldehyde:

Wardrobe hanging bags made of bamboo charcoal can remove the odor of clothes, and can also prevent moisture, sterilization, and insect repellent. Putting bamboo charcoal in your new wardrobe will completely remove the smell of wood and adhesive in less than a week.

Leave furniture in rooms that don't live with people. The most reliable way is ventilation. Ventilation is to allow natural air circulation to carry away the odor of the wooden wardrobe.

On the basis of ventilation, wipe the paint part of the surface with a wet towel when you have time, and then carefully wash it with soap, which will promote the volatilization of trace undesirable gases that re-penetrate the paint surface. Wipe twice a day.

Close the cabinet door at night and put grapefruit peel, residual tea leaves, activated charcoal, etc.; In addition, it also prevents the cabinet door from drying and drifting, so don't wait until the smell is out and the door can't be closed. In the morning, open the doors and windows to ventilate the hall.

It is recommended that the home should be kept regularly ventilated and more plants should be placed, such as cactus, spider plant, tiger tail orchid, ivy, iron tree, chrysanthemum, etc. You can use Qingmanlu nano photocatalyst to remove aldehyde, spray it irregularly for about a week every day, you can remove 90% of formaldehyde, and you can reduce formaldehyde to it, so you will not worry about formaldehyde harming health.

1. Formaldehyde in textiles.

Formaldehyde is mainly used in fiber products as a dyeing aid and a resin finishing agent to improve the anti-wrinkle and anti-shrinkage effect. Formaldehyde can make the color of the textile bright and bright, maintain the durability of printing and dyeing, and make the cotton fabric wrinkle-proof, anti-shrinkage and flame retardant. Therefore, formaldehyde is widely used in the textile industry.

2. Formaldehyde in glue.

Most of the wood-based panels used in furniture are made of urea-formaldehyde resin glue, which is extremely unstable, and will decompose and release formaldehyde when exposed to moisture and heat, so wood-based panels are the main source of formaldehyde release, and it is also the focus of formaldehyde treatment. A small amount of formaldehyde is present in paints and coatings and fabric furniture.

3. Formaldehyde in curtains, fabric textiles, and wall wallpaper.

Curtains, fabric textiles, walls, wall paints, etc., in the process of processing and production, add formaldehyde-containing adhesives, or as preservatives directly add formaldehyde, therefore, it is also a source of formaldehyde release for the new home.

1.A large part of formaldehyde comes from the cheap viscose inside the man-made board - urea formaldehyde resin, in addition to gypsum board, paint, plastic products, adhesives may also contain formaldehyde, because the preparation process is simple, the raw materials are easy to obtain, so that urea formaldehyde resin is still one of the cheapest adhesives, but also one of the most important free formaldehyde in home decoration.

2.Since it is inevitable, how to remove formaldehyde?

First of all, it is necessary to control the source of pollution and minimize the source of indoor pollution.

In addition, when purchasing building materials and furniture, you can go to the big shopping mall to buy qualified quality products, you can also use activated carbon, such as arrowstone, bamboo charcoal, etc., which has a developed pore structure and specific surface area, and can adsorb formaldehyde into its own voids, activated carbon is only adsorbed so it is easy to be saturated, and the effect of wisdom stone is better while adsorbbing and decomposition, and wisdom stone is a natural ore, not black or white ball particles, if you see someone using ball particles to pretend to be wisdom, please stay away from it. There are many types of activated carbon, but the porosity of coconut shell charcoal is the best! Secondly, keep the ventilation smooth, and the indoor floor can be wiped with water frequently!

Formaldehyde pollution at home is mainly in furniture, flooring, and home, if the wallpaper glue used for wallpaper is of poor quality, the glue also contains a large amount of formaldehyde, and there is also a curtain fabric adhesive that also contains formaldehyde, and the boss in the furniture is an important source of formaldehyde, especially the plate is a composite board, and a large amount of formaldehyde will be used to make glue.
