Editor's Note : The Quality Supervision Bureau announced the results of the quality inspection of 43 types of kitchen furniture produced by the city's enterprises. Among them, the problem of formaldehyde emission has once again attracted people's attention.
Formaldehyde: It is a colorless and easily soluble irritating gas. It is gaseous at normal temperature and usually appears in the form of an aqueous solution. It is a very strong fungicide with antiseptic, sterilization and stabilizing effects. It is determined by the World Health Organization as Carcinogenic and teratogenic substances.
The effects on human health are mainly manifested in olfactory abnormalities, stimuli, allergies, abnormal lung function, abnormal liver function and abnormal immune function. Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, menstrual disorders in women, pregnancy syndrome, and nasopharyngeal cancer.
E1 grade and E0 grade: all of the free formaldehyde content of the board, wherein the free formaldehyde content of E1 grade is ≤1.5mg/L, and the formaldehyde content of E0 grade is ≤0.5mg/L.
Problem analysis
Environmental protection cabinets are more than "formaldehyde does not exceed the standard"
The cabinet incident not only brought another crisis to the industry, but also brought new questions for consumers to buy. How to buy cabinets, how can we buy products that meet environmental requirements?
It is understood that the current environmental standards for cabinets have yet to be further improved, and the environmental protection requirements of the cabinet industry mainly refers to the amount of formaldehyde released from the cabinet panels. Excessive formaldehyde content in the kitchen will have a stimulating effect on human skin, conjunctiva, respiratory mucosa, etc., causing respiratory and eye diseases, etc., which are very harmful to the human body. The most direct way to identify whether it is environmentally friendly is to have the relevant test report issued by the merchant. However, the environmental protection of cabinets is a comprehensive concept. "Formaldehyde does not exceed the standard" is only one of the important aspects. Others include chemical pollution, physical damage and garbage pollution.
Chemical pollution: In addition to formaldehyde, there may be harmful substances such as benzene, ammonia, and harmful heavy metals in the cabinet. In addition to the panel, there are also cabinets and adhesives that need to be treated in order to ensure that the content of harmful substances does not exceed the standard.
Materials, poorly-made cabinets, there may be burrs, sharp corners, etc. in the details, these unreasonable parts, it is easy to cause harm to the body. Inferior cabinets may also be contaminated with noise, radioactivity, etc. To avoid these problems, high-quality hardware is required to properly select panels and countertops.
Whether energy-saving design: the choice of sink directly affects the amount of tap water used. The single large sink is more water efficient than the currently popular double sink; because the double sink can be dip and washed separately, it can be used more reasonably. The setting of the gas stove should avoid the tuyere as much as possible. If it is installed at the door, the gas will be affected by the flowing air when it is used. Not only the use of gas will increase, but also the soot will be blown away by the wind and will not be absorbed intensively, which will affect the smoke. Machine work.
Garbage pollution: The kitchen has always been regarded as the “manufacturing workshop†of garbage. It has become commonplace to soil the floor and block the sink. If the residual garbage is not properly cleaned, it will easily breed bacteria and attract four evils. If a set of cabinets is poorly designed or the quality of the fittings is defective, the garbage cans are unreasonably set or quality problems are likely to cause garbage pollution.
Unsafe to use: Cabinets are a place where water, electricity and gas are collected. If these three things are not used properly, they will cause harm to the environment and even affect personal safety. The overflow in the sink should be properly set; electrical appliances, wires and plugs should be protected from leakage; gas valves, flameout protection, etc. Although these are not directly related to the cabinet, it is integrated with the design and installation of the cabinet, so it must be taken into consideration at the beginning of the installation of the cabinet.
