Formaldehyde printing and dyeing auxiliaries are more cotton textiles, and most of the commercially available "cotton wrinkle-proof" clothing or iron-free shirts use formaldehyde-containing auxiliaries, which may release formaldehyde when worn.

    Formaldehyde in children's clothing mainly comes from dyes and additives that maintain the bright and beautiful color of children's clothing, as well as adhesives used in garment printing. As a result, the formaldehyde content of bright and printed clothing is generally high, while the aldehyde content of plain clothing and non-printed children's armor is low.

    2. Formaldehyde in food.

    Present in aquatic foods. Because formaldehyde can keep the color of the surface of the water food bright, it can increase toughness and crispness, improve the taste, and can also preservative, if it is used to soak seafood, it can fix the seafood form and maintain the color of the fish. Formaldehyde has been detected in the main water foods on the market:

    Duck paw, beef shutter, shrimp, sea cucumber, fish maw, pomfret, octopus, cuttlefish, hairtail, squid head, hoof tendon, sea snail, snail meat, cuttlefish larvae, etc., among which the formaldehyde content in shrimp, sea cucumber and squid is higher.

    Found in pasta, mushrooms, or soy products. Formaldehyde can whiten and change color, so formaldehyde is often used by unscrupulous traders to fumigate or directly add to pasta, mushrooms or soy products. Formaldehyde has been detected in related foods such as shiitake mushrooms, mushrooms, rice noodles, vermicelli, yuba, etc.

    Formaldehyde in indoor air.

    3. Formaldehyde in household air.

    Man-based panels such as plywood, blockboard, MDF and particleboard used for interior decoration. The adhesive used in the production of wood-based panels takes formaldehyde as the main component, and the residual and uninvolved formaldehyde in the board will be gradually released to the surrounding environment, which is the main body of formaldehyde in the indoor air.

    Furniture made of wood-based panels. In order to pursue profits, some manufacturers use substandard boards, or use inferior glue when bonding veneer materials, and the formaldehyde in the boards and glues seriously exceeds the standard.

    Other types of decorative materials that contain formaldehyde and may be emitted to the outside world, such as wall coverings, wallpaper, chemical fiber carpets, paints and coatings, etc.

    4. Formaldehyde in chemicals.

    Formaldehyde can come from cosmetics, detergents, pesticides, disinfectants, preservatives, printing inks, paper, etc.

    5. Formaldehyde generated.

    When foam slats are used as heat-proof, cold-proof and insulating materials for houses, under the action of light and heat, the foam ages and deteriorates to produce synthetic compounds and release formaldehyde.

    Hydrocarbons can generate formaldehyde gas through photochemical synthesis, organic matter can also form formaldehyde through biochemical reactions, and also contains a large amount of formaldehyde in combustion exhaust gas, such as 7kg of formaldehyde gas can be generated for every 1000L of gasoline burned, and even formaldehyde gas is generated when a cigarette is lit.

    6. Formaldehyde in automobiles.

    Formaldehyde also comes from interior decoration materials such as seat covers, cushions and headliners, with the most prominent formaldehyde emission in new cars.

    7. Formaldehyde in air pollution.

    Formaldehyde has been among the best in the list of toxic gases in our country, long-term contact with formaldehyde is harmful to health, and formaldehyde must not be a fluke, it is recommended that you can do a formaldehyde test to detect whether the indoor formaldehyde content exceeds the standard, formaldehyde once it exceeds the standard, it is necessary to immediately do a good job of removing aldehyde measures, the following is recommended for you to remove several aldehyde tips, so that you can easily remove formaldehyde.

    1. Putting some green plants at home can also effectively remove odors, especially like pothos, spider plant, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.

    2. This is a gift from nature to us, and it is the most economical way to remove aldehyde, as long as the window is opened, fresh air will enter the room, and formaldehyde will be purified by dilution.

    3. Activated carbon to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

    5. High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying.

    6. The principle of the fresh air system is ventilation, the outdoor fresh air is filtered and transported to the room, and then the harmful substances containing formaldehyde are discharged outdoors to achieve the effect of removing formaldehyde

    1. Ventilation method: open doors and windows to ensure that the north and south are breathable, generally 2 months for its effect 2, physical adsorption method, plants, charcoal bags, live ores and other materials can be put more on it.

    3. Low-temperature nano-scale membrane permeation purification technology, the Dialin herbal method used in this technology 4. Chemical blocking, using chemical reagents to seal pores.

    On the whole, most methods have their own advantages and disadvantages, relatively speaking, the use of herbal decomposition technology has become a relatively ideal choice for purifying indoor air.

    Choosing the right plant can effectively remove a part of formaldehyde, but the plant is easy to wither, and the effect is too slow, formaldehyde is very stubborn, especially some inferior materials, the release life of formaldehyde may be as long as decades, the following is for you to introduce several methods of aldehyde removal, and which plants can remove aldehyde, I hope you can control formaldehyde efficiently.

    1.Opening windows for ventilation is a zero-cost method for indoor formaldehyde removal, and it is also a more practical method. However, the ventilation method also has many limitations, which has a certain relationship with the house type and location, and the formaldehyde release life in the decoration materials is very long, only using the method of opening the window to ventilate the indoor formaldehyde problem is too slow, and the ventilation method can only be used as an auxiliary method to control formaldehyde.

    2.Now the company in addition to formaldehyde can be seen everywhere, this industry is now very chaotic, in the first and the effect of formaldehyde removal have deviated, in the choice of the choice must choose a reliable formaldehyde removal company.

    3.Using activated charcoal is also a great option. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

    4.The fresh air system is similar to the ventilation method of removing formaldehyde, but there is no need to open the window when in use, and the air delivered to the room is filtered, and it is also used when it exceeds the standard.

    5.We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire.

    Formaldehyde is very harmful to the human body, and it is recommended to use a combination of methods when dealing with it, so as to stabilize the formaldehyde concentration in a safe range faster!
