Problems solved by technology

[0007] In actual use, the volatilization time of free formaldehyde generally lasts for 10 to 15 years. In the above two formaldehyde scavengers, the active ingredients added are limited. Once the effectiveness fails, free formaldehyde in the wood-based panel will still be released in large quantities. come out, causing indoor air pollution. In addition, when the formaldehyde scavenger reacts incompletely with formaldehyde, it may also generate other toxic substances and cause secondary pollution.

Embodiment 1

[0025] Since the existing man-made boards use phenolic and urea-formaldehyde resins containing formaldehyde in the production process, while the furniture and home decoration building materials made of such boards are used by people, the residual and unreacted formaldehyde in the boards It will be gradually released to the surrounding environment, and the longest release period can reach 15 years. For this reason, formaldehyde has become the main body of indoor air pollution. The timeliness of the product is poor, and once the effectiveness fails, a large amount of free formaldehyde in the wood-based panel will still be released, causing indoor air pollution, etc. In order to solve the defects of the existing technology, the present invention proposes an indoor formaldehyde remover Formula, the formaldehyde remover is mainly used for indoor environment, using the combination of physical adsorption and chemical reaction to achieve the complete removal of formaldehyde, not only c...

Abstract

The invention discloses an indoor methanol remover formula which comprises the following components: 100 parts of adsorbent carrier, 16-72 parts of ethylene group urea, 4-5 parts of accelerant and 2-4 parts of essence. The formula adopts the ethylene group urea and the adsorbent carrier which are matched for use, the ethylene group urea is loaded on the adsorbent carrier, and when the adsorbent carrier performs physical adsorption on methanol in air, the ethylene group urea loaded on the adsorbent carrier can make a chemical reaction with the methanol to finally convert the methanol into a nontoxic and odorless substance, so that the methanol is thoroughly removed; the formula is convenient to use, low in price, and pollution-free; practice proves that the air quality is obviously improved after use of the formula; and the formula is particularly suitable for daily household use.

Description

technical field [0001] The invention belongs to the field of formaldehyde removal, and specifically relates to an indoor formaldehyde elimination agent formula. Background technique [0002] Formaldehyde has always been considered as the number one suspected carcinogen in indoor pollution, and it usually comes from decoration, decoration materials, furniture and coatings, etc., especially wood-based panels and the adhesives they use. Wood-based panels, plywood, particleboard, fiberboard, composite flooring, etc., they use phenolic and urea-formaldehyde resins containing formaldehyde in the production process. According to statistics, more than 90% of domestic wood-based panels are pressed with urea-formaldehyde glue, so of course there will be problems during application. Free formaldehyde, used in furniture manufacturing or other panel applications, often has a certain impact on the human body. In the actual application process, the reasons for the generation of free forma...
