Application of urea-formaldehyde resin powder
Urea-formaldehyde resin powder is also called urea-formaldehyde resin powder. The English abbreviation UF is the polycondensation of urea and formaldehyde under the action of a catalyst (alkaline or acid catalyst) to form an initial urea-formaldehyde resin powder, and then under the action of a curing agent or auxiliary agent, it forms an insoluble and infusible final thermosetting resin. The cured urea-formaldehyde resin powder is lighter in color than phenolic resin, translucent, resistant to weak acids and alkalis, has good insulation properties, excellent wear resistance, and is cheap.
Urea-formaldehyde resin powder can be used for products that do not require high water resistance and dielectric properties, such as power strips, switches, machine handles, instrument housings, knobs, daily necessities, decorations, mahjong tiles, toilet lids, and some tableware. ‘s manufacture.
Urea-formaldehyde resin powder is the most used variety of adhesives. Especially in the manufacture of various wood-based panels in the wood processing industry, urea-formaldehyde resin and its modified products account for about 90% of the total amount of adhesives. However, in the presence of strong acid and alkali, it is easy to decompose, has poor weather resistance, poor initial viscosity, large shrinkage, high brittleness, no water resistance, and easy aging. The wood-based panels produced with urea-formaldehyde resin powder have formaldehyde release during the manufacturing and use process. problem, so it must be modified.
