Formaldehyde is an organic chemical substance, a colorless gas with a pungent odor. When formaldehyde exceeds a certain concentration, it may reduce the body's respiratory function, the information integration function of the nervous system and affect the body's immune response . It has irreversible harm to all systems of the body. When we buy latex paint, businesses often claim that their latex paint does not contain formaldehyde. So, can latex paint really be formaldehyde-free?
In fact, formaldehyde is the raw material of latex paint - a substance that will definitely evaporate from the emulsion. All latex paints will inevitably contain formaldehyde. The formaldehyde content of high-quality latex paint fully complies with relevant national standards. The official formaldehyde test result of Kanamei water-based paint is "not detected", which can meet the standard of being ready to be painted and lived in.
However, the formaldehyde content in your home is the result of the joint action of building materials, decorative materials and furniture. Even if you are painted with Konamine water-based paint which has ultra-high environmental standards, it is best not to relax your vigilance about the air quality in your home. After the decoration is completed and all the furniture is brought into the site, find a CMA laboratory or a professional formaldehyde testing and management company for testing to get truly meaningful test results.
There are various methods for formaldehyde control on the Internet, which can basically be divided into three categories: physical adsorption, biological absorption and chemical decomposition. The first two can basically only be used as placebos. The most obvious feature is that in the effectiveness promotion, there are only explanations of the principles and no quantitative experiments. Chemical decomposition products will basically be more credible, with quantitative calculations, laboratory tests, processes and data. Therefore, to control formaldehyde, if it needs to be effective in a short time under very strict conditions without ventilation, it is okay to ask a professional treatment team to use chemical reaction methods. However, it should also be noted that spray reactants are generally not suitable for open surfaces of solid wood furniture, high-end fabrics and leather.
However, the release period of formaldehyde is as long as 3-15 years. In view of this characteristic, the easiest and long-term effective method to remove formaldehyde is ventilation. Keep the windows open all day in summer, and add an industrial fan when there is no wind and hot weather. In winter, in order to maintain temperature and humidity, you can keep it airtight for a few days and ventilate it for one day.
To summarize, as long as we maintain a reasonable density of furniture and building materials, ensure adequate ventilation, and purchase building materials that are as environmentally friendly as possible, we can avoid excessive indoor formaldehyde concentration to the greatest extent.
