Melamine urea-formaldehyde utomoni ndi condensation product of reaction between formaldehyde, urea and melamine. Ma resinswa achulukitsa kukana kwa madzi ndi nyengo, kuwapangitsa kukhala oyenera kupanga mapanelo oti agwiritse ntchito panja kapena chinyezi chambiri. Ma resin awa amapereka magwiridwe antchito apamwamba kuposa mapanelo, zomwe zimapangitsa kuti zikhale zokwera mtengo kwambiri. Ma resins awa ndi zomatira zomwe zimagwiritsidwa ntchito kwambiri popanga zida zomangira.
Mapulogalamu: matabwa opangidwa ndi laminated (LVL), particleboard, medium density fiberboard (MDF), plywood.
Melamine urea-formaldehyde resins amapezeka mumitundu yosiyanasiyana ya melamine kuti akwaniritse zofunikira zamakasitomala osiyanasiyana, ndipo zogulitsa zimatha kupangidwa mogwirizana ndi zomwe kasitomala amafuna.
1. Kupanga mipando yamatabwa: Urea-formaldehyde utomoni ufa angagwiritsidwe ntchito kumanga matabwa, plywood, pansi matabwa ndi mipando ina yamatabwa. Zili ndi mphamvu zomangirira kwambiri komanso kukana kutentha, ndipo zimatha kupereka mgwirizano wokhalitsa.
2. Makampani opanga mapepala: Urea-formaldehyde utomoni ufa ukhoza kugwiritsidwa ntchito ngati cholimbikitsira pakupanga zamkati kuti apange mphamvu ndi kukana madzi kwa pepala. Ikhoza kupanga mgwirizano wamphamvu pakati pa ulusi ndikuwonjezera mphamvu yolimba komanso kulimba kwa pepala.
3. Zida zoyaka moto: Urea-formaldehyde utomoni ufa ukhoza kusakanizidwa ndi zinthu zina kupanga zokutira zotchingira moto ndi zomatira zoletsa moto. Zida zomwe zimayaka moto zimagwiritsidwa ntchito kwambiri pazida zamagetsi, zomangamanga, ndi zoyendera kuti zipereke chitetezo chachitetezo chamoto.
4. Makampani okutira: Urea-formaldehyde resin ufa angagwiritsidwe ntchito kupanga zokutira zokhala ndi kutentha kwabwino komanso kukana nyengo. Zovala izi zimakhala ndi kukana kwabwino kwambiri komanso kukana mankhwala ndipo zimagwiritsidwa ntchito kwambiri pamagalimoto, zomangamanga ndi zina.
5. Makampani opanga nsalu: Urea-formaldehyde utomoni ufa umakhalanso ndi ntchito zambiri pamakampani opanga nsalu. Ikhoza kugwiritsidwa ntchito popanga zomatira za nsalu zosiyanasiyana, monga silika, nsalu za ubweya, ndi zina zotero. Nsalu yomwe imagwirizanitsidwa ndi urea-formaldehyde resin ufa imakhala ndi madzi amphamvu komanso osasunthika, ndipo sizovuta kuzimiririka ndi kuwonongeka. Kuphatikiza apo, urea-formaldehyde resin ufa angagwiritsidwenso ntchito popanga zinthu zosiyanasiyana zoteteza madzi ku nsalu, anti-wrinkle agents, etc., kupanga nsaluyo kukhala yokongola komanso yothandiza.
6. Zomatira: Urea-formaldehyde utomoni ufa angagwiritsidwe ntchito ngati zomatira wamba zitsulo, galasi, zoumba ndi zipangizo zina. Ili ndi kukana kwamadzi bwino komanso kukana kwamankhwala ndipo ndiyoyenera kugwiritsa ntchito zida zosiyanasiyana zamafakitale.
Mwachidule, urea-formaldehyde resin ufa ndi zomatira zapamwamba kwambiri zolimba komanso kukana madzi. Amagwiritsidwa ntchito kwambiri polumikiza zinthu monga matabwa, mapepala, ndi nsalu. Kuphatikiza apo, urea-formaldehyde resin ufa amathanso kugwiritsidwa ntchito popanga zinthu zowononga, zotchingira zotchingira, zokutira zotsutsana ndi dzimbiri, ndi zina zambiri, ndipo zimakhala ndi ntchito zambiri komanso chiyembekezo chogwiritsa ntchito.
