Chemical experts tell us: formaldehyde is widely used in synthetic resins, plastics, rubber, leather, paper, dyes, pharmaceuticals, pesticides, photographic film, explosives, building materials, as well as disinfection, fumigation and anti-corrosion processes. It can be said that formaldehyde It is a "all-rounder" in the chemical industry. However, the use of anything must be limited, once the use exceeds the standards and limits, it will bring a negative side. According to reports: formaldehyde has the following major health hazards: stimulating effects: First, the main hazard of formaldehyde is the stimulation of skin mucosa. Formaldehyde is a virgin substance that binds to proteins and causes severe respiratory irritation and edema, eye irritation, headache, and bronchial asthma. Second, sensitization: direct contact with formaldehyde can cause allergic dermatitis, pigmentation, necrosis, often inhaled a small amount of formaldehyde, can cause chronic poisoning, mucosal congestion, skin irritation, allergic dermatitis, nail keratosis and fragility, A The bed is painful at the fingertips. Third, mutagenic effect: high concentration of formaldehyde is also a genotoxic substance. Long-term inhalation of pregnant women may cause deformity or even death of newborn babies. Long-term inhalation of men can lead to sperm deformity and death in men. In this way, the "pet" of formaldehyde is like an untrained "bad dog." Once out of control, it will be seriously hurt. The most hateful unscrupulous traders have actually “transplanted†formaldehyde used in industry into the food field, and “preserving fresh vegetables†for vegetables, which can be called “grass and human lifeâ€.
Knowing that formaldehyde is harmful to human health, why are businesses still abusing, or even treating it as their own "pet"? First, the businesses involved are not only lacking in morality, but also lacking a minimum sense of responsibility. As long as the product can sell, he is sick and infected, and it is dark and dark. So, "poisonous furniture" has driven many people out of the house, consumers are afraid of facing seafood, and the housewife hears the news of formaldehyde dishes. Secondly, the use of formaldehyde is low in cost and quick. According to industry insiders, the main reason for formaldehyde abuse in manufacturing is its low price. Even if it is used excessively, it is forbidden to go public at most. This is not enough for those who "take a shot and change places". According to chemical experts, in recent years, China has successfully developed a formaldehyde-free finishing agent and an environmentally friendly urea-formaldehyde resin that does not contain formaldehyde. However, it has not been put into production much today, mainly because the cost is too expensive. It can be seen that the cheap price hinders the replacement process of formaldehyde, and it also shows that formaldehyde is still the “darling†of the chemical industry for a long time to come. Therefore, only strict supervision of the production field, just like other dangerous chemical products, requires companies to strictly use the standard, more than one point must be severely punished. Entrepreneurs know the truth: to be a product and behave like a person, you will produce a "good" product and you will get a good return. Otherwise, it is difficult to escape the strange circle of retribution - you sell toxic furniture, and you may eat "formaldehyde vegetables" in your mouth. Formaldehyde use
