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. I-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%. Kodwa-ke, i-Urea-formaldehyde Resin kulula ukubola lapho kuvezwa ama-acid aqinile kanye ne-alkalis. Inokumelana kahle kwesimo sezulu, i-viscosity yokuqala empofu, i-shrinkage enkulu, i-brittleness, ukumelana kwamanzi, kanye nokuguga okulula. Amabhodi okufakelwa akhiqizwa nge-Urea-formaldehyde resin akhiphe i-formaldehyde ngesikhathi senqubo yokukhiqiza nokusebenzisa. Inkinga, ngakho-ke kufanele kuguqulwe.

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 uhlobo oluvame ukusetshenziswa kokunamathela. 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%.
