Treatment of Formaldehyde in Ji Hong, Harbin: The sooner in addition to formaldehyde is renovated, the better?

Decoration of in addition to formaldehyde is not as soon as possible. With the current technology, there is no method or product that can completely remove formaldehyde in home decoration at one time. Therefore, in addition to formaldehyde should be prepared for long-term persistence. There are some special short-term in addition to formaldehyde products on the market, which are characterized by quick effect and good removal effect in seven days, so that customers can confirm receipt and praise them during this period. However, the removal effect of this product can only last for half a month at most. If short-term pollution control products are used, the control effect is very obvious within half a month after the product takes effect, but after half a month, the product gradually reaches saturation. If we continue to use it after saturation, formaldehyde will be released from it, causing secondary pollution. The reason why formaldehyde is difficult to remove is that the formaldehyde hidden inside the plate is difficult to remove.
