What happens to plastics with excessive formaldehyde after burning

Residue after formaldehyde combustion.

Plastics are mainly caused by odors, and there are more benzene series exceeding the standard, and there is no more ventilation. Formaldehyde is an adhesive present in furniture and is volatile for a long time.

1. Open doors and windows to maintain good ventilation.

2. An appropriate amount of activated carbon and leaf clay materials can be put into the room for adsorption; Ye Guangni is a relatively emerging physisorption material, with the characteristics of porous structure of formaldehyde removal materials, he has tiny pores to contain formaldehyde, toluene and other harmful gas molecules.

3. The release time of formaldehyde is as long as 3-5 years, and it is recommended to buy some plants that remove formaldehyde after moving in: spider plant, tiger tail orchid, ivy, aloe vera and other plants can absorb some harmful substances such as formaldehyde to a certain extent.

Formaldehyde is harmful, the taste of plastic will essentially contain formaldehyde, formaldehyde has serious harm to human health, when the indoor formaldehyde reaches a certain concentration, the human body will have discomfort, greater than the greater than the formaldehyde concentration can cause eye redness, itchy eyes, throat discomfort or pain, hoarseness, chest tightness, asthma, dermatitis, etc. The release of formaldehyde is long-term, with a period of 3 to 15 years, and it cannot be completely eliminated if it only relies on ventilation. It can be supplemented with some other materials.

1. After ventilation, the use of some Yeguang mud activated carbon can dilute formaldehyde, and remember to keep ventilation at home. Ye Guang mud and activated carbon are different materials, different things, activated carbon just has a simple adsorption function, adsorption taste is OK, but it will be saturated. Ye Guang mud has the function of adsorption, locking and decomposing harmful substances.

2. Plant selection aloe vera, spider plant, tiger tail orchid, one-leaf orchid, and monstera are natural aldehyde plants, which can also help decorate the house and relax the mood.

Plastic does not produce formaldehyde anymore.

Plastic is a general term for polymers, there are many types, commonly used plastic products in life such as plastic bags, plastic boxes, etc., the main component is polyvinyl chloride, generally does not contain formaldehyde; Plastic products used in industrial production or furniture may contain formaldehyde, plastics containing formaldehyde generally have the word "aldehyde" in the name, and the most common plastics containing formaldehyde are polyoxymethylene plastics, phenolic plastics, urea formaldehyde foam, polyvinyl formaldehyde foam, etc.

Formaldehyde and aldehydes are indeed used as important industrial raw materials in chemical manufacturing, and many plastic products will also use it in the synthesis process, formaldehyde is often used as preservatives, solvents, rubber curing agents, redox agents, etc. in industrial production, but most of the plastic products that come into contact with in life do not contain formaldehyde.

Formaldehyde is produced under certain conditions, such as some hydrocarbon substances, which will decompose to produce formaldehyde under high temperature sunlight incineration conditions, when plastic products are in thermal shock, strong ultraviolet rays, high humidity and high pressure or react with other substances, they will be deformed, and formaldehyde may also be decomposed to produce formaldehyde, but the content is generally not too large, so pay attention not to buy inferior products when using plastic products, and stay away from heat sources.

Qualified plastic products do not release harmful gases that are harmful to health at room temperature. However, when they are exposed to extreme environments, such as thermal shock, strong ultraviolet light, high humidity and pressure, or reaction with other substances, they can cause plastic products to become unstable or even decompose to produce harmful gases, including formaldehyde. However, this usually only happens under conditions of high temperatures or even combustion.

As important industrial raw materials, formaldehyde and aldehydes play an important role in chemical manufacturing, and many plastic products are also used in the synthesis process. In industrial production, formaldehyde can be used as a preservative, solvent, rubber curing agent, redox agent, etc. Although aldehydes are widely used industrial raw materials, the aldehyde group is quite active, and it often reacts with other substances and groups in the synthesis process to be consumed, and no longer exists in the form of aldehyde groups.

The vast majority of plastics we come into contact with every day do not contain formaldehyde or other aldehydes in their finished products.

Now many children's toys are plastic products, many parents are worried that often play with children's toys may harm children's health, after all, plastic products contain a lot of toxic substances, and some also contain formaldehyde, so children's plastic toys will have formaldehyde?

Do children's plastic toys have formaldehyde?

Every child will be accompanied by a variety of toys when they grow up, and parents will buy a variety of toys suitable for children in the process of children's growth. Some novice parents are very confused about how to buy toys and the safety of toys.

First of all, in general, many toys on the market today are toxic, can harm health, and contain formaldehyde. Therefore, parents need to pay special attention when purchasing. Most low-quality toys are made of cocoaplastic or mixed with other materials.

The material is hard, dense, with few impurities, and the product is fragile. It is best not to buy such toys for your baby.

In addition, it should be noted that some plush toys are not suitable for small babies to play with, because the main problem of plush toys is the lack of logos and material descriptions, etc. In addition, there are some plush toys with many small parts that can be disassembled, and children are easy to swallow and suffocate.

Finally, there are many things to pay attention to when buying toys for your baby, check whether the toys contain harmful chemicals, and do not buy some toys made of flammable materials. And be careful not to be cheap. It is essential to choose products with quality assurance and material safety.

In this way, the safety of the baby's body can be guaranteed, and the baby can also play more happily.

How to use the remote control of children's remote control toy car?

There must be additional product manuals and manufacturers and related certifications, mainly because many products are now made of ** waste, which is not harmful to the health of children.

In many cases, parents rarely ask about the remote control distance when they buy a children's remote control car, and the distance of the current remote control car is also from 20 meters, 30 meters, 40 meters, etc. In the comparison of more than a dozen remote control cars, in general, the ** of the remote control car = the remote control distance of the remote control car (of course, this needs to exclude the trick remote control car and the oil burning remote control car), so when buying, you must understand the remote control distance of the remote control car in detail, so that the baby can better experience the fun brought by the remote control car in the process of playing!

The position of the remote control car when the switch is turned on**Whether the speed of the toy wheel is uniform when rotating, and whether there is a sudden reversal or sudden stop. If everything is checked normally, still hold the toy in your left hand and use your right hand to move the sounder, **Whether the toy wheel will suddenly change the direction of rotation, and check the sensitivity of the switching action. Check the anti-interference ability of the toy, place the toy at a distance of about 1 meter, whistle or speak softly, and observe whether the toy will malfunction.

There are many remote control actions in the car, and the sensitivity of the control is checked one by one when selecting. Pay special attention to the antenna of the transmitter to the longest at the beginning of the inspection, and then slowly shorten the antenna when everything is normal.

Generally speaking, plastic does not contain formaldehyde, but if it has been contaminated with some materials containing formaldehyde, it may carry formaldehyde.

1. Inferior plastic toys do contain formaldehyde, so parents should be cautious when purchasing. National toy safety regulations require that all toys should be made from clean and pollution-free materials. Toys are something that children are often exposed to and are also their favorite gifts.

2. If it contains a large amount of formaldehyde, it will seriously endanger the health of children. At present, market research shows that non-standard manufacturers have formaldehyde exceeding the standard mainly in two aspects: one is raw materials.

On the one hand, there is paint. In terms of raw materials, many unscrupulous businesses actually reuse waste plastics and even medical waste to make toys, children play with not only smell, touch, but also in the mouth, many black-hearted manufacturers in order to reduce costs, the use of medical waste to make toys, which leads to excessive formaldehyde. In terms of paint, the paint itself has a lot of heavy metals exceeding the standard, if in order to reduce costs, the use of substandard paint can often make toys in lead, benzene and other heavy metals exceed the standard.
