Problems solved by technology

For example, some strong oxidizing formaldehyde scavenger can oxidize formaldehyde, but it is easy to decompose itself. Spraying it on the wood will directly damage the wood, and it will lose its effectiveness within a few hours.

Abstract

The invention discloses a formaldehyde removing agent. The formaldehyde removing agent comprises the following components in parts by weight: 1-5 parts of glycine, 0.8-3 parts of chitosan quaternary ammonium salt, 0.5-1 part of dencichine, 0.5-1 part of maca root extractive, 1-5 parts of glycerin, 0.5-1 part of triethyl citrate water solution, and 100-150 parts of de-ionized water. The formaldehyde removing agent can effectively remove formaldehyde in furniture boards, is convenient to use and low in cost, can avoid formaldehyde recurrence after use, cannot generate secondary environment pollution in the product use process, and is long in acting time, more thorough in treatment and high in formaldehyde removing rate.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an aldehyde remover. Background technique [0002] Formaldehyde, also known as formaldehyde. A colorless gas with a special pungent smell, which is irritating to human eyes and nose. The main harm of formaldehyde is shown as the stimulation to skin mucous membrane. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable, which is greater than 0.08m 3 High formaldehyde concentrations can cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, wheezing, dermatitis, etc. Newly decorated rooms have higher levels of formaldehyde, which is the main cause of many diseases. Long-term exposure to formaldehyde increases the risk of certain cancers such as Hodgkin's lymphoma, multiple myeloma, and myelogenous leukemia. At present, the methods of removing formaldehyde mainly include activated carbon...
