(formaldehyde) (film protein) (water)
2、 Product characteristics:
This product is made of domestic innovative biotechnology, using oxidation hydrolysis of biological protein as the main raw material, adding active enzyme and plant essence extracted from pure plants, and combining biological enzyme catalysis, adsorption and decomposition technology. The solid color of this product is white, the aqueous solution is colorless, tasteless, non-toxic, the PH value is basically neutral, no corrosion, will not damage the sprayed wood or articles, and has a unique adsorption and cleaning capacity for harmful gases such as formaldehyde.
The product adopts its own process of penetration to make it reach the deep layer of the material directly, and react with harmful substances such as formaldehyde in the material quickly to generate a tasteless, non-toxic, and non decomposable water-soluble substance, which can thoroughly clean free formaldehyde and reduce the formation of secondary pollution.
Formaldehyde cleaning rate is up to 90% or more. The use of formaldehyde in wood-based panel products will not change the physical and chemical indicators of wood-based panels, but will significantly improve the product grade of wood-based panels and produce E1 and E0 grade wood-based panels. This product is soluble in water and easy to absorb moisture. After absorbing moisture, it becomes a sticky film.
3、 Main purpose:
1. It is used for indoor pollution of houses, offices, hotels, hospitals, school buildings and cars after decoration. During indoor decoration, formaldehyde in various decorative materials such as wood-based panels and coatings is removed.
2. It is used for cleaning formaldehyde in adhesives and coatings containing free formaldehyde, which can reduce free formaldehyde to less than 0.1% (GB18584-2001).
3. Used for formaldehyde cleaning in plywood, particleboard, (medium and high density fiberboard) and blockboard.
4、 Usage:
1. When it is used for indoor environmental pollution control, first clean the surface of the articles to be treated comprehensively, and then treat the inside and outside of the articles to be treated by brushing, spraying and injection, or spray on the wall surface, dosage: 5-12ml/m two (within ten times of the standard), that is, 100-200 m per kg of biological aldehyde scavenging enzyme can be treated two In case of serious exceeding standard, secondary spraying can be carried out.
2. When used for adhesives and coatings, add appropriate amount of water to dissolve it, which can be properly heated at 60 ℃ (small batch can be mixed at room temperature) to dissolve into colorless transparent colloidal body, and directly add it to the adhesives and coatings that need formaldehyde removal.
3. When it is used for plywood, particleboard, medium and high density fiberboard and blockboard, it can be added during glue mixing, which can significantly reduce formaldehyde emission and will not change the physical indicators of wood-based panels.
