Unqualified adhesives contain a variety of toxic and harmful substances, such as curing agents, volatile organic compounds, diluents, plasticizers, other additives and fillers, etc. These substances will enter the human body through various channels and endanger human health.
(1) Volatile organic compounds
Volatile organic solvents in solvent-based adhesives will cause serious indoor air pollution and endanger human health. Such as ammonia emitted from acrylate emulsion, formaldehyde emitted from trialdehyde adhesive, unreacted monomer emitted from acrylate emulsion adhesive, styrene emitted from unsaturated polyester adhesive, polyisocyanate emitted from polyurethane adhesive, etc.
(2) Toxic curing agents and plasticizers
Aromatic amine curing agents are very toxic, and some even cause cancer, such as m-phenylenediamine. Dibutyl phthalate, tricresyl phosphate and dioctyl phthalate in plasticizers will also do great harm to human health, and excessive inhalation will lead to endocrine disorders.
(3) Toxic and harmful fillers
There are many kinds of fillers used in adhesives, which have serious environmental pollution. For example, the diameter of cotton powder fiber filler is very small. If it is not handled properly, these fibers will rise, then invade the human body through the respiratory tract and even the capillary pores of the human body, and gradually accumulate in the lungs, which may induce serious diseases such as lung cancer, bronchial cancer or mesothelioma.
(4) Toxic and harmful additives
The viscosity of adhesive depends largely on additives, including azodiisobutyronitrile and dibutyltin dilaurate. However, these additives are toxic and can cause serious damage to human body.
the world health organization tells us that 68% of human diseases are caused by air, 8% by respiratory pollution, and more than 8% by respiratory injury. In recent ten years, with the improvement of rental decoration, all kinds of cancers, hematological diseases, malignant diseases and strange diseases are related to indoor air pollution, but unfortunately more than 9% people don't know!
how should we clear it?
traditionally, professional companies use sealing agents to block the formaldehyde and other pollutants emitted from the painted surfaces of furniture. However, due to the limited dosage and self-volatilization, formaldehyde will evaporate freely after the "drug effect". What's more, some sealing agents are inherently polluting.
Photocatalyst in addition to formaldehyde is a chemical in addition to formaldehyde method that was eliminated earlier. Although photocatalyst has excellent ability to treat free formaldehyde under the action of ultraviolet light, it has no ability to treat formaldehyde emission sources deeply hidden in the depths of the plate. In addition, ultraviolet light is harmful to human body, so few people use photocatalyst in addition to formaldehyde in recent years.
It is relatively wise to open the window and ventilate for several months or even a year before moving in; If it is treated with scavenger and sealing agent, it will avoid the peak period of formaldehyde release, and it will be better. However, it has become common knowledge that formaldehyde can be released for as long as 3-15 years. Therefore, it is not uncommon for children to suffer from hematological diseases after renovation for seven or eight years.
Since 22, many high-end places are no longer "in addition to formaldehyde", and they all use high-energy physics technology to do "internal cleaning", thus realizing fast and safe check-in.
Guangdong Taichang Environmental Protection Technology Co., Ltd. has been focusing on the physical technology of indoor air treatment for more than 1 years, and has successfully developed the patented technology of "low-temperature plasma sauna" and Taichang 5A air processor. By using the deep plasma infiltration technology, it carries out sauna neutralization reaction on the hidden harmful substances release sources such as concrete, wood-based panels, paint layers, textiles and mattresses.
With the internal cleaning technology, the pollution sources such as formaldehyde, benzene, toluene, xylene, ammonia, TVOC and odor can be eradicated in only 3 days, thus eliminating the rebound phenomenon. Internal cleaning technology has ended the history of "2-year chemical agent in addition to formaldehyde".
