Problems solved by technology

However, the disadvantages of this type of formaldehyde scavenger are: although the effect is quick, it will rebound after a period of time, and even cause some plates to deform, which is easy to cause secondary pollution; most of the plant-extracted formaldehyde scavenger uses Euonymus Euonymus, Sansevieria, and Clivia , Pineapple and other natural plants are used as adsorption materials. The disadvantages of this type of formaldehyde scavenger are: the effect is slow, the removal efficiency is not high, and the pollution problem cannot be solved for a while.

Embodiment 1

[0022] Weigh respectively 700g of pulverized spirit herb powder, 250g of ammonium bicarbonate, CaCl 2 50g, mix well and distribute in equal amounts in 20 well-sealed bottles. Used to remove formaldehyde from a newly purchased desk with 6 drawers: open the caps of 12 of the above-mentioned bottles containing formaldehyde scavenger, put 2 capped bottles of formaldehyde scavenger in each drawer, and then close the drawer .

[0023] After 10 days, it was detected that the concentration of formaldehyde in the drawer changed from 0.41mL / m to the original closed 60min. 3 , reduced to 0.08mL / m 3 Below; in the room where the desk is placed, the concentration of free formaldehyde in the air is reduced to 0.08mL / m after the doors and windows are closed for 12 hours 3 the following.

Embodiment 2

[0025] Weigh respectively 1360g of pulverized spirit herb powder, 540g of ammonium bicarbonate, CaCl 2 100g, mix well and distribute in equal amounts in 20 well-sealed bottles. It is used to remove formaldehyde from a newly purchased wardrobe with 5 doors: first open the caps of 10 above-mentioned bottles containing formaldehyde scavenger, disperse them in the wardrobe, and then close the door of the wardrobe.

[0026] After 15 days, it was found that the concentration of formaldehyde in the closet changed from the original 0.38mL / m2 closed for 60 minutes. 3 , reduced to 0.08mL / m 3 Below; in the room where the wardrobe is placed, the concentration of free formaldehyde in the air is reduced to 0.08mL / m after the doors and windows are closed for 12 hours 3 the following.

Embodiment 3

[0028] Weigh respectively 1380g of pulverized spirit herb powder, 540g of ammonium bicarbonate, CaCl 2 80g, mix well and distribute in equal amounts in 10 well-sealed bottles. Used to remove formaldehyde in a newly purchased car: Open the caps of the 5 above-mentioned bottles containing formaldehyde scavenger, disperse them in the car, and then close the doors and windows.

[0029] After 15 days, it was found that the formaldehyde concentration in the car changed from the original 0.28mL / m after 60 minutes of closure. 3 , reduced to 0.08mL / m 3 the following.

Abstract

The invention belongs to the biotechnical field and discloses a formaldehyde scavenging agent. The formaldehyde scavenging agent is prepared from the following components in percentage by weight: 65-70% of lysimachia foenum-graecum powder, 25-25% of ammonium hydrogen carbonate and 5-10% of CaCl2. The formaldehyde scavenging agent disclosed by the invention can be used for effectively scavenging formaldehyde in rooms, automobiles and furniture and has the advantages of quick formaldehyde scavenging speed, high efficiency, convenience in use and simple formula.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a formaldehyde scavenger. Background technique [0002] Formaldehyde is a highly toxic substance, and it ranks second on the list of priority control of toxic chemicals in my country. Formaldehyde is defined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. Formaldehyde can spontaneously react with free amino groups on proteins, DNA, and RNA to denature proteins and nucleic acids. After the chemical reaction with formaldehyde, the genetic code formed by the base arrangement on the DNA encoding the protein will also change accordingly, resulting in gene mutation and, in severe cases, cancer. Excessive formaldehyde in the air of newly decorated interiors and newly purchased cars is one of the most harmful pollutants to the human body. [0003] Studies have ...
