Thermosetting resin. Yakarapwa urea-formaldehyde resin yakareruka muruvara pane phenolic resin, inopenya, inoshingirira kune isina kusimba asidhi uye isina simba alkali, ine yakanaka yekudzivirira zvivakwa, yakanakisa kupfeka kuramba, uye yakachipa. Ndiwo anonyanya kushandiswa akasiyana pakati pezvinonamira, kunyanya mukugadzirwa kweakasiyana mabhodhi ekugadzira muindasitiri yekugadzira huni, urea-formaldehyde resin uye zvigadzirwa zvayo zvakagadziridzwa zvinokwana makumi mapfumbamwe muzana ezvese zvekunamira kushandiswa. Zvisinei, urea-formaldehyde resin iri nyore kuora kana yaiswa kune yakasimba acids uye alkalis. Iine kusamira zvakanaka kwemamiriro ekunze, kushata kwekutanga viscosity, shrinkage yakakura, brittleness, kusamira kwemvura, uye kuchembera nyore. Mabhodhi eArtificial anogadzirwa neurea-formaldehyde resin inoburitsa formaldehyde panguva yekugadzira nekushandisa maitiro. dambudziko, saka rinofanira kugadziriswa.

Application
