Formaldehyde is a colorless gas with a strong pungent smell. Chemical formula: HCHO. Soluble in water, alcohols and ethers. Formaldehyde is a gas at room temperature, usually in the form of aqueous solution, soluble in water and ethanol.
Formaldehyde is an important organic raw material, mainly used for synthetic binder, used in the production of urea-formaldehyde resin and phenolic resin, from formaldehyde and urea according to a certain mole ratio reaction to produce urea-formaldehyde resin. Phenolic resin was prepared by mixing formaldehyde and phenol in a certain molar ratio.
Health hazards of formaldehyde
Studies show that formaldehyde has strong carcinogenic and carcinogenic effects. The effects of formaldehyde on human health are mainly manifested in abnormal smell, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function.
Mild wheezing occurs in children at concentrations of 0.06-0.07 mg/m per cubic meter of air. When the formaldehyde content in indoor air is 0.1mg/m, there is a peculiar smell and discomfort; when it reaches 0.5 mg/m, it can stimulate the eyes and cause tears. Up to 0.6 mg/m, may cause throat discomfort or pain. Higher concentrations can cause nausea and vomiting, cough chest tightness, asthma and even pulmonary edema; at 30 mg/m, death occurs immediately.
Long-term exposure to low doses of formaldehyde can cause chronic respiratory disease, caused by nasopharyngeal carcinoma, colon cancer, brain tumor, menstrual disorders, the nucleus gene mutations, even on single DNA stated and DNA and protein LianJi inhibit DNA damage repair, pregnancy complications, neonatal chromosome abnormality, leukemia, their memory and mental decline.
In all the contacts, children and pregnant women are particularly sensitive to formaldehyde, and the harm is greater. It is a major pollutant in decoration and furniture. Its release period lasts for 3-15 years, and it will volatilize from the deep layer of the material in case of heat and tide, seriously polluting the environment and becoming a difficult worldwide problem to solve. The elderly, children and pregnant women are most vulnerable.
Formaldehyde harms: light people have nasal, pharynx, throat discomfort and burning sensation, runny nose, pharynx pain, cough, etc., serious people have chest pressing feeling, dyspnea, headache, upset, etc. Long-term excessive inhalation of formaldehyde can cause nasopharyngeal cancer, laryngeal cancer and other serious diseases.
Formaldehyde release characteristics
1, formaldehyde is a release half-life, wood-based panels and other formaldehyde release cycle is 3 to 15 years.
2, with the rise of temperature and humidity, the release of formaldehyde will accelerate.
3, with the reduction of temperature and humidity, the release of formaldehyde will slow down.
4. In the same closed space, when formaldehyde release reaches a certain concentration in the air, the release of pollution sources will stop. When the concentration of formaldehyde in the air is reduced by ventilation, the pollution source will continue to release formaldehyde.
And all aluminum furniture products all choose aluminum alloy profile structure and element design, not afraid of water is not afraid of moisture, can be directly washed with water and clean sanitation, and not moldy. The most important thing is that all aluminum furniture products can achieve zero formaldehyde. With the news that the new house formaldehyde exceeds the standard in recent years, every new house decoration residents are most worried about health and environmental protection problems, and formaldehyde has become the biggest worry of residents.
All aluminum furniture solves this problem, and can make customers feel at ease using it without worries. Moreover, the surface of all aluminum furniture products has strong heat resistance, which overcomes the shortcomings of traditional wooden furniture that is easy to burn.
In addition, the overall structure and elements of all aluminum furniture can be fire retardant. After the use life of all-aluminum household products, their materials can be recycled and reused at a guaranteed price, which greatly improves the effect of recycling and reduces the waste of social resources and environmental pollution caused by waste reuse.
