Coating technology: the way to reduce the residual formaldehyde content in urea formaldehyde resin

It is suggested that the content of residual formaldehyde in urea formaldehyde resin is strictly required by the state For this reason, a new assistant for eliminating residual formaldehyde, high formaldehyde glue and formaldehyde reducing partner, has been developed in China This kind of high aldehyde gum reducing aldehyde partner is composed of pure natural plant extract and a variety of formaldehyde capturing substances The formaldehyde emission of plywood can reach E0 level by adding a certain proportion of glue, which solves the international problem that the formaldehyde emission of plywood is always high The formaldehyde reducing companion with high formaldehyde glue can completely lock a large amount of residual formaldehyde in urea formaldehyde resin glue, home decoration materials and man-made products, quickly eliminate the irritating smell, and at the same time Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: the state has strict requirements for residual formaldehyde content in urea formaldehyde resin For this reason, a new assistant for eliminating residual formaldehyde, high formaldehyde glue and formaldehyde reducing partner, has been developed in China This kind of high aldehyde gum reducing aldehyde partner is composed of pure natural plant extract and a variety of formaldehyde capturing substances The formaldehyde emission of plywood can reach E0 level by adding a certain proportion of glue, which solves the international problem that the formaldehyde emission of plywood is always high The formaldehyde reducing companion with high formaldehyde glue can completely lock a large amount of residual formaldehyde in urea formaldehyde resin glue, home decoration materials and artificial products, quickly eliminate the pungent smell, and have the function of catching ammonia and other harmful gases The product does not contain any harmful substances and elements and will not cause secondary pollution Compared with similar products, it has the characteristics of tasteless, colorless, non reactive, non binding, non peeling and non irritant It is applicable to all boards, clothing, fabrics, carpets containing aldehydes and ketones, as well as aldehydes reduction treatment for offices, restaurants, family rooms, cars and boats, KTV rooms, newly decorated rooms, and new furniture It has the advantages of rapid action, large proportion of aldehyde reduction, simple use and no influence on the basic properties of the adhesive Compared with the traditional method of reducing the molar ratio and other formaldehyde eliminating products, the product will not affect the prepressing, bonding strength and water resistance of urea formaldehyde adhesive It can improve product quality, reduce production cost and improve product grade It can also be widely used to eliminate free formaldehyde in urea formaldehyde, phenol formaldehyde, melamine acetal resin, polyvinyl acetal (107 glue) and white latex The use of aldehyde reducing companion of high aldehyde glue (1) When it is used in urea formaldehyde resin adhesive or polyvinyl acetal adhesive, it is added into the adhesive in a certain proportion (2) Before the pressure plate sizing, just mix a certain amount of the product and the glue evenly Mix well after adding (3) For the finished wood-based panel with excessive formaldehyde emission, thick spraying is required Lwj-1000 is a colorless or yellowish transparent liquid with pH value (25 ℃) 7.5 ± 0.5 and relative density (20 ℃) 1.021 ± 0.02 The home of coatings focuses on coatings, diatom mud, paint coating, coating technology, fire-resistant coating news and coating, diatom mud, paint coating, coating technology, Decoration knowledge and effect drawing of fireproof coating,
