Word:[Big][Middle][Small] QR Code 2019/10/16     Viewed:    
With the acceleration of modern urbanization and the improvement of people's living standards, indoor air pollution caused by excessive decoration has posed a serious threat to human health.
According to the statistics of indoor air quality test reports since 2002, 80% of the families' indoor air quality can not meet the requirements of the national standard, and 90% of the families that fail to pass the air quality test are caused by formaldehyde exceeding the standard.
Therefore, formaldehyde is the most dangerous pollutant in the indoor environment. Formaldehyde scavenger products came into being in response to market demand.
Now we will introduce the harm, source and characteristics of formaldehyde in detail
Harm of No.1 formaldehyde
As the second place in the priority control list of toxic chemicals in China, formaldehyde has been identified as carcinogenic and teratogenic substance by the World Health Organization. It is recognized as a source of allergy and one of the potential strong mutagens. It is considered that there is a causal relationship between formaldehyde and leukemia.
Formaldehyde can cause obvious irritation to eyes, respiratory tract, mucous membrane and skin of human body; acute poisoning can lead to tears, runny nose, cough and other symptoms, leading to a variety of respiratory diseases; chronic inhalation of low concentration can lead to continuous headache, weakness, insomnia, etc.; long term inhalation of low dose can cause chronic respiratory diseases, female menstrual disorders, neonatal physical deterioration, chromosomal abnormalities Often, even induce nasopharyngeal carcinoma.
Source of No.2 formaldehyde
Through the analysis of indoor formaldehyde, the main sources of formaldehyde are as follows:
1) Plywood, blockboard, MDF and particleboard are used for interior decoration.
2) Furniture made from wood-based panels.
3) other decorative materials containing formaldehyde, such as white latex, foam plastics, paint and coatings.
4) From the interior decoration textiles, including bedding, wall cloth, wallpaper, chemical fiber carpet, curtain and fabric furniture.
Characteristics of No.3 indoor formaldehyde pollution
1) The pollution cycle is long. According to the national environmental protection product quality supervision and inspection center, some rooms still have the problem of formaldehyde exceeding the standard after 10 years of decoration.
2) Over standard is serious. In the rooms tested by the national environmental protection product quality supervision and inspection center, most of the rooms exceed the standard by 4-5 times, and some even exceed the standard by more than 10 times.
What is formaldehyde scavenger?
Formaldehyde scavenger is a kind of liquid product which can reduce the concentration of formaldehyde in the air. It can contact the formaldehyde in the air to the maximum extent by spraying on the indoor wall surface, decoration surface and other objects suitable for painting, so as to absorb and convert formaldehyde into safety substances.
Industry status of formaldehyde scavenger products
With the improvement of people's understanding of the harm of formaldehyde, people's demand for formaldehyde scavenger products has increased sharply. Only one building material supermarket has achieved an annual sales of 3.8 million yuan of formaldehyde scavenger. Under the stimulation of huge market demand, many enterprises rush into this industry. At present, there are more than 500 enterprises producing formaldehyde scavenger products in China.
The formaldehyde scavenger products on the market are mainly divided into two categories, one is the power type air purifier using electric power, the other is the air purification material relying on its own performance, the latter is more energy-saving and environmental protection.
According to the different purification principles, formaldehyde scavenger products can be roughly divided into physical scavenger, chemical scavenger, biological scavenger and pseudo scavenger.
The formaldehyde scavenger produced by Ribao is mainly made of active polyamine compounds. It is used to remove formaldehyde and acetaldehyde in polymer, especially suitable for removing acetaldehyde in pet, so as to meet the requirements of food and beverage packaging, and also suitable for removing formaldehyde and acetaldehyde in acetic acid resin, adhesive and paint.
