  • Hazards of formaldehyde

Formaldehyde is more toxic substances, toxic chemicals in our list of priority control of the second highest formaldehyde. Formaldehyde World Health Organization has been identified as carcinogenic and teratogenic substances, is a recognized source of allergy is potentially strong mutagenic One thing. Studies have shown that formaldehyde has a strong carcinogenic and tumor promotion. Effects of formaldehyde on human health is mainly manifested in abnormal sense of smell, irritation, allergy, pulmonary function abnormalities, liver dysfunction and immune dysfunction and other aspects of its concentration in reached 0.06-0.07mg / m3, per cubic meter of air children occurs in mild asthma; when the indoor air formaldehyde content of 0.1mg / m3, there is smell and discomfort; reach 0.5mg / m3, it can stimulate the eyes, causing tears; reach 0.6mg / m3, can cause throat discomfort or pain; at higher concentrations, can cause nausea, vomiting, cough, chest tightness, shortness of breath or pulmonary edema; reaching 30mg / m3, would immediately cause death.
Formaldehyde damage to health evidence
Professor, School of Life Sciences, Central China Normal University, Yang et al., Recent animal experiments, from the level of molecular biology research confirms indoor formaldehyde pollution genotoxic and carcinogenic effects, neurological and reproductive toxicity effects on the human body, oxidative damage to cells, toxicity eye and airway irritation and immune system.
As a country 'fifteen' scientific and technological issues 'major pollutants in indoor air health hazard assessment technique' of sub-topics, Yang and other researchers used simulation technology exposure, according to the general pollution of indoor formaldehyde levels were 2.24 mg / cubic meter and 4.81 mg / cubic meter gaseous formaldehyde perfused mice was observed by molecular biomarkers of airway (nasal and bronchial) neurons with edema and inflammation when exposed to elevated levels of formaldehyde, a corresponding increase in the frequency of the test volunteers blink, The higher the concentration of formaldehyde prompted more intense eye irritation.
With 3 mg / cubic meter concentration of formaldehyde gas in mice exposed to 7 days, 6 hours per day, the researchers found that glutathione mouse brain, heart, liver, lung, kidney, testes and other organs have antioxidant effects level and superoxide dismutase (SOD), glutathione peroxidase vigor has declined, indicating that formaldehyde in addition to causing damage to the outer Hu respiratory tract can also cause oxidative damage to other organs or systems, it is a systemic toxicant. Experiments confirmed that stimulation of gaseous formaldehyde pollution can also lead to chromosome breakage, resulting in oxidative damage to DNA molecules directly inhibit SOD activity, so that the free radical scavenging adverse indirect cause oxidative damage DNA molecules, and potentially carcinogenic Effects of Brain tissue antioxidant enzyme activity resulting in reduced free radical scavenging slow, a lot of accumulation, resulting in neuronal damage, neurobehavioral changes in water maze test in mice, the formaldehyde exposure on learning and memory in mice, Compared with the control group was significantly lower.
In addition, rats exposed to formaldehyde can cause testicular damage, reproductive cells have damaging effects, but also to formaldehyde-specific antibody levels increased, reduced immunity, so is exposed objects become 'acquired allergies

  • How do we achieve to formaldehyde products

Our main product is added to the titanium dioxide

Nano TiO2 has a very valuable optical properties, in the automotive industry and many other areas have shown a good development prospects. Nano TiO2 also has a high chemical stability, thermal stability, non-toxic, super-hydrophilic, non-migratory, and is fully in contact with food, so is widely used UV materials, textiles, light catalytic catalyst, self-cleaning glass, sunscreen, paint, ink, food packaging materials, paper industry, aerospace industry, lithium batteries.

  • Formaldehyde principle

Photocatalyst [Photocatalyst] light [Photo = Light] + catalyst (catalyst) [catalyst] compound words. Photocatalyst is a nano-sized titanium

In addition to formaldehyde photocatalytic reaction principle
Dioxide collectively optical semiconductor material having a photocatalytic function on behalf of the current international governance indoor environmental pollution ideal material.
Photocatalyst under the irradiation of light, will produce similar photocatalytic reactions of photosynthesis, resulting in a strong oxidation free hydroxyl and reactive oxygen species, a strong light redox function, there are a variety of oxidized decomposition *** *** compound and part no matter, can damage cell membranes and cure viral proteins of bacteria, can kill bacteria and decomposition of pollutants *** to *** pollutants have decomposed into non-polluting water (H2O) and Carbon dioxide (CO2), which has a strong bactericidal, deodorant, anti-mildew, anti-fouling and self-cleaning, air purification function.

  • Advantages of our products

1. Comprehensiveness: photocatalyst can effectively degrade formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other pollutants, and a highly efficient broad-spectrum disinfection performance, bacteria or fungi can release toxins decomposition and harmless treatment .
2. Continuity: During the reaction, photocatalyst itself does not change and the loss, in the light irradiation may be continuous purification of pollutants, with long-lasting, the advantages of continuing role.
3. Safety: non-toxic, harmless to human safety and reliability; final reaction product is carbon dioxide, water and other harmless substances, no secondary pollution.
4. Efficiency: photocatalyst use inexhaustible solar energy will be able to diffusion of environmental contaminants at low concentrations status clear purification.
