How to control formaldehyde release |
Update:2016/8/8 |
Currently formaldehyde has been identified as carcinogenic and mutagenic substances WHO, is one of the potential strong mutagenic carcinogenic, one of the things, if the release of excessive will seriously harm human health. Study shows that the new house renovation finished containing formaldehyde, the release of the incubation period of up to 15 years. Green League in addition to formaldehyde experts learned that a citizen in the renovation of 8 years later, still detect the formaldehyde content of furniture exceeded more than doubled.
State General Administration of quality supervision, inspection and Quarantine of the wood furniture manufacturing enterprises to detect found, there are at least 15 kinds of toxic chemicals in each enterprise, up to 31, seriously overweight; the benzene exceeded the enterprises occupying 89.0%, exceeding the highest 121.5 times; formaldehyde enterprises accounted for 76.9%, the high standard 116 times. "Furniture formaldehyde content exceeds the standard, mainly due to the processing of the process, once the plate, glue, paint formaldehyde content can not be guaranteed, the formaldehyde content of furniture will not consciously exceeded. In addition, in order to reduce the cost, the enterprise to buy inferior plate. And environmental protection materials, low formaldehyde content but the cost is relatively high, and poor plate comparison, the difference between the price of 60-100 yuan per block." At present, in accordance with the state regulations, the amount of formaldehyde in furniture should be less than M2 0.15mg/. Green League in addition to formaldehyde, said: sometimes manufacturers procurement is more environmentally friendly E0, E1 plate, but in the process of processing, because the glue, paint and other factors also cause excessive formaldehyde. "Even if the use of green building materials can not guarantee excessive formaldehyde, although enterprises have materials certification standards, but in the production process, if the inspection is not strict, it can not guarantee that it is environmentally friendly." Indoor air governance furniture surface decoration method for the closure of formaldehyde is very obvious. In the specific implementation process, we should pay attention to the use of low formaldehyde release of adhesive, a variety of decorative materials and coatings and reasonable process to ensure that the decoration does not lead to the release of a new formaldehyde. Indoor air treatment using the environment on furniture formaldehyde emission has a great impact. Temperature, humidity and ventilation will affect the formaldehyde emission. Under normal climatic conditions, the temperature increase of 8 degrees Celsius, the formaldehyde concentration in the air will be doubled; the humidity increases by 12%, the formaldehyde emissions will increase by about 15%. Therefore, under the conditions of the premise, you can use air conditioning and fresh air system devices to adjust the indoor temperature and humidity and fresh air volume, so that the emission of formaldehyde emission control. The Green League Environmental Protection Technology Co., Ltd. was established in 2003, specializing in providing Foshan in addition to formaldehyde, photocatalyst in Foshan, Foshan in addition to smell, Foshan in addition to the paint fumes, Foshan houses in addition to taste, Foshan air purification, Foshan formaldehyde detection service is national the earliest in the photocatalyst, in addition to formaldehyde, decoration pollution control of large enterprises is the first master photocatalyst in addition to formaldehyde in addition to pollution of core technology and application of high-tech enterprises, environmental protection industry association member units.
