Embodiment Construction

[0013] 1. Preparation of formaldehyde remover:

[0014] First add 125 liters of distilled water into a 250 liter container, then take 1000 grams of triethanolamine, 250 grams of sodium metabisulfite, 250 grams of disodium edetate, 2,3,4,5,6-pentahydroxy 500 grams of hexanal (the above four substances are analytically pure), respectively added to the aforementioned distilled water successively, stirred while adding to make it fully dissolved, to obtain a concentrated solution of formaldehyde remover, then packaged for easy transportation and use The aforementioned formaldehyde remover is diluted to 1000 grams (by weight) with distilled water before, and the pH value is close to 8.

[0015] 2. Application experiment:

[0016] Apply the formaldehyde remover of the present invention according to the aforementioned method: after 24 hours of emptying (opening the doors and windows) of the decorated room, and then closing the room (closing the doors and windows) for 24 hours, detect...

Abstract

A formaldehyde remover for the aldehyde-contained adhesive and the flyboard is prepared from triethanolamine, sodium dimetasulfite, Na2EDTA, 2,3,4,5,6-pentahydroxy hexyaldehyde and distilled water through proportion and compounding. It has high effect on removing formaldehyde from indoor air.

Description

technical field [0001] The invention relates to a formaldehyde remover, in particular to a aldehyde-containing adhesive, a synthetic board production plant, and when it is used for interior decoration, the formaldehyde remover can be used to remove free formaldehyde therefrom. Background technique [0002] Along with the raising day by day of people's living standard, interior decoration is very common. However, when aldehyde-containing (such as urea-formaldehyde, phenolic, etc.) production plants, synthetic board (plywood, density board, etc.) The space causes serious pollution, irritates people's eyes, mouth, nasal cavity, etc., and endangers people's health. The above-mentioned problems have caused widespread concern in the society, and it is hoped that they can be resolved at an early date. Therefore, how to remove the pollution of free formaldehyde to indoor air has become a subject that scientific and technical personnel pay attention to. ...
