The reporter has just learned from Shandong Zhucheng Liangfeng Chemical Co., Ltd. that soybean protein is hydrolyzed by amino acid, and the active enzyme extracted from pure plants is added to desalinate urea formaldehyde resin (a kind of adhesive with formaldehyde as the main raw material), paint The new product of free formaldehyde in latex paint - biological aldehyde scavenging enzyme (also known as amino acid hydrolyzed soy protein) was successfully developed by the environmental science and technology research institute of the enterprise. This product can also quickly clean formaldehyde emitted from decorative materials such as wood-based panels, furniture, wallpaper, carpets, etc.
It is reported that biological aldehyde scavenging enzyme has solved the worldwide problem in the field of formaldehyde pollution, and its debut has been highly praised by famous departments and users. It has been awarded the title of "Green Star" by the Environmental Protection Industry Association (Certificate No two thousand and seven Lu 06 No.), and is approved to use the special logo for environmental protection. Due to its major technological breakthrough and internationally advanced overall performance, it has been identified as a provincial scientific and technological achievement and accepted as an invention achievement (Application No.: two hundred billion seven hundred and ten million one hundred and fourteen thousand seven hundred and ninety-one )。 Through the relevant appraisal organized by the Science and Technology Department of Shandong Province, it is confirmed that the development of this product has successfully filled the domestic gap and reached the advanced level of similar products in the world.
Song Liang, chairman of Zhucheng Liangfeng Chemical Co., Ltd., told reporters that at present Formaldehyde treatment products on the market can be roughly divided into the following five categories:
The priority is the blocking agent, which is mainly composed of film-forming substances, such as polyvinyl alcohol, chitosan and other polymer resins, to form transparent films to block formaldehyde.
The second type is the oxidant that can oxidize formaldehyde, such as the mixed solution composed of strong oxidants such as hydrogen peroxide and chlorine dioxide. Oxidation of free formaldehyde molecules plays a role in adsorbing formaldehyde pollution;
The third type is ammonia derivatives, which are used to make formaldehyde capture agent to clean formaldehyde;
The fourth type is activated carbon, macromolecules adsorb and wrap formaldehyde molecules;
The fifth type is photocatalyst.
In principle, the blocking agent blocks the source of formaldehyde release, which is a good way. However, in the actual use process, furniture will gradually be exposed to re release formaldehyde after a long time of wear and tear, and lose its function; Although the use of oxidant formaldehyde treatment products can temporarily reduce formaldehyde pollution to a certain extent, most oxidant formaldehyde treatment products are generally chemically toxic, and improper use can easily cause secondary pollution of indoor air; Formaldehyde treatment products produced by ammonia derivatives are generally unstable, even reversible, and will decompose and release formaldehyde under high temperature and humidity; The activated carbon adsorption has the problem of saturation point. As we all know, the adsorption capacity of activated carbon is limited, and it is obviously unrealistic to place no amount of activated carbon in a polluted space; The cleaning effect of photocatalyst on formaldehyde requires very harsh reaction conditions, which has long been described in many domestic scientific papers.
Biological aldehyde scavenging enzyme is produced by adopting unique biotechnology, using amino acid to hydrolyze biological protein, combined with enzyme catalytic compound and other technologies. It can penetrate into the deep layer of the material and react quickly with formaldehyde, Produce a non-toxic, tasteless and non decomposable macromolecule material, so as to thoroughly clean free formaldehyde, without causing secondary pollution, which is truly green Environmental protection products 。 The product was tested by the Environmental Protection Product Quality Supervision and Inspection Center (CMA2006002118Z), and the formaldehyde removal rate of indoor formaldehyde was more than 91.5%; It is recognized as actually non-toxic and non hazardous chemicals by the Center for Disease Control and Prevention (CMA2006000919S) and the Chemical Dangerous Goods Identification Center of the State Administration of Work Safety; The wood-based panel quality supervision and inspection center (CNAL2006002118Z) conducted a comparative test on samples. The product can not only clean formaldehyde in wood-based panels, but also significantly improve other physical indicators of wood-based panels.
It is understood that biological aldehyde scavenging enzyme not only improves the formaldehyde hazard caused by decoration pollution, but also brings good news to furniture and wood-based panel manufacturing enterprises. Many wood-based panels and furniture manufacturers have greatly reduced the formaldehyde release of their products after using biological aldehyde scavenging enzymes, which can meet the EU E0 and E1 very high formaldehyde release standards. The workshop workers generally respond that the pungent and choking smell has disappeared when the biological aldehyde scavenging enzymes were not used before, the working environment has been greatly improved, and the workers are more energetic than before.
At present, this product is not only used for urea formaldehyde resin and wood-based panels, but also gradually extended to coatings, clothing, leather, textile, printing and dyeing, sewage treatment and other fields; We believe that the extensive promotion and application of biological aldehyde scavenging enzyme will make great contributions to these industries! It can be predicted that the sooner biological aldehyde clearing enzyme is applied to production and people's life, people will be protected from formaldehyde one day earlier, and improve people's quality of life and social ecological civilization.
It is reported that the product has been mass produced. 0536-2165528 15064403497 Zhao Yan
