The importance of preventing formaldehyde
Formaldehyde is one of the indoor pollution problems that everyone is concerned about, but everyone is thinking about how to treat formaldehyde. In fact, the prevention of formaldehyde is more important than treatment.
That is to say, before long-term use of the product, the index of formaldehyde emission must be tested. For example, man-made panels, laminate flooring, panel furniture, paint, latex paint and other products that may contain formaldehyde.
When formaldehyde reaches a certain concentration, it will be harmful to the human body. Some people say that formaldehyde can be smelled with the nose, but formaldehyde is a colorless and toxic chemical substance. People can breathe formaldehyde into the body. It has a pungent odor, but it can only be smelled when the concentration of formaldehyde is high. When the concentration of formaldehyde is low, it is difficult for people to detect it by smell.
The method to prevent formaldehyde production is to detect the index of formaldehyde emission, which can be tested by a device dedicated to detecting formaldehyde emission index. The following editor will introduce you a special device for detecting formaldehyde-formaldehyde climate chamber.
The formaldehyde climate chamber is suitable for the determination of formaldehyde emission of various man-made panels, composite wood floors, carpets, carpet underlays, carpet adhesives and other indoor decoration materials, and can be used for the detection of other volatile harmful gases. Really simulate the indoor climate environment, and the test results are closer to the real environment, so it is true and reliable.
The size of the test piece is length=(1000±5)mm, width b=(1000±5)mm. The surface area of the test piece is one square meter, and the "1 cubic meter climate chamber method" will last for at least 10 days. Under the action of constant temperature, constant humidity and constant airflow, the measurement starts from the 7th day. When the number of tests exceeds 4 and the difference between the two measurement results before and after is less than 5%, the average value is taken as the measurement result. If the difference between the two measurement results is greater than 5%, it must be measured once a day. If the stable state is not reached within 28 days, the measured value on the 28th day can be used. Before and after the formaldehyde emission limit value is less than 0.124mg/m3, it is qualified.
Before you want to use artificial boards and composite floors for a long time, you must first check and find that the formaldehyde exceeds the standard and take effective measures in time! As long as precautions are in place, formaldehyde is not terrible.
