Ukuchazwa Komkhiqizo
I-Urea-formaldehyde Resin (UF), eyaziwa nangokuthi i-Urea-formaldehyde Resin, i-polycondenstation ye-urea ne-arkalidehyde esetshenziswayo ye-urea-formaldehydehyde resin, bese yenza isigaba sokugcina nesingenasisekelo ngaphansi kwesenzo se-ejenti elapha noma isengezo. Thermosetting resin. I-Urea-formaldehydehyde Resin ilula ngombala kunemibala ye-phenolic resin, i-translucent, ukumelana nama-acid abuthakathaka kanye ne-alkali ebuthakathaka, inezakhiwo ezinhle zokuvimbela, futhi zishibhile. Kuyindlela esetshenziswa kakhulu phakathi kwezikhangiso, ikakhulukazi ekwenziweni kwamabhodi okufakelwa ahlukahlukene embonini yokusebenza kwezinkuni, i-Urea-formaldehyde resin kanye nemikhiqizo yayo eguquliwe ye-90% yokusetshenziswa okunama-adhesive cishe ama-90%. However, urea-formaldehyde resin is easy to decompose when exposed to strong acids and alkalis. It has poor weather resistance, poor initial viscosity, large shrinkage, brittleness, water resistance, and easy aging. Artificial boards produced with urea-formaldehyde resin release formaldehyde during the manufacturing and use process. problem, so it must be modified.

Isicelo
Ingasetshenziswa kwimikhiqizo engadingi ukumelana kwamanzi okuphezulu kanye nezakhiwo ze-dielectric, ezifana nemichilo yamandla, izibani zezinkuni, amathayili we-mahjong, futhi nazo zingasetshenziswa ekwenziweni kwetafula elithile.

Urea-formaldehyde resin is the most commonly used type of adhesive. Ikakhulu ekwenziweni kwamapulangwe ahlukahlukene okufakelwa embonini yokwakha izinkuni, i-Urea-formaldehyde resin kanye nemikhiqizo yayo eguquliwe i-akhawunti cishe ama-90% okusetshenziswa okunama-adhesive acishe abe ngu-90%.
