Produkt beschreiwung
Urea-formaldehyde resin (UF), also known as urea-formaldehyde resin, is the polycondensation of urea and formaldehyde under the action of a catalyst (alkaline or acidic catalyst) to form an initial urea-formaldehyde resin, and then forms an insoluble and infusible final phase under the action of a curing agent or additive. Thermotinging Resin. Cured urea-formaldehyde resin is lighter in color than phenolic resin, translucent, resistant to weak acids and weak alkali, has good insulation properties, excellent wear resistance, and is cheap. It is the most commonly used variety among adhesives, especially in In the manufacturing of various artificial boards in the wood processing industry, urea-formaldehyde resin and its modified products account for about 90% of the total adhesive usage. Wéi och ëmmer, urea-formaldehydsing Resin ass einfach ze entsuergen, wann se fir staarksäck an Alkalis ausgesat. Et huet schlecht Wieder Resistenz, aarm initial Viskositéit, déi grouss Ofrälung, grommelegkeet, Widderhuelungsorganisatioun, an einfacher Agestioun. Kënschtlech Brieder produzéiert mat Urea-formaldehyds Resin Réhodhydyde wärend der Fabrikatioun a benotzt Prozess. Problem, also muss et geännert ginn.
