Sharaxaada Alaabta
Urea-formaldehyde resin (UF), oo sidoo kale loo yaqaan urea-formaldehyde resin, waa polycondensation of HOL iyo formaldehyde ee hoos yimaada ficilka kicinta (alkaline ama kicinta acidic) si ay u sameeyaan urea-formaldehyde hore, ka dibna waxay sameeyaan aan la milmi karin wejiga kama dambaysta ah ee aan la fahmi karin Xabagta kululaynta. Xabagta urea-formaldehyde ee la daweeyay ayaa midab ahaan ka khafiifsan xabagta phenolic, translucent, adkaysi u leh asiidhka daciifka ah iyo alkali daciifka ah, waxay leedahay sifooyin dahaar wanaagsan, caabbinta xidhashada aad u fiican, waana raqiis. Waa noocyada ugu badan ee loo isticmaalo xabagta, gaar ahaan marka la soo saaro looxyada macmalka ah ee kala duwan ee warshadaynta alwaaxyada, urea-formaldehyde resin iyo alaabteeda wax laga beddelay ayaa ah qiyaastii 90% wadarta isticmaalka koollada. Si kastaba ha ahaatee, xabagta urea-formaldehyde way fududahay in la burburiyo marka ay la kulmaan asiidh xooggan iyo alkalis. Waxay leedahay iska caabin cimilo oo liidata, viscosity bilowga liidata, yaraanshaha weyn, jajabnaanta, iska caabinta biyaha, iyo gabowga fudud. Looxyada macmalka ah ee lagu soo saaray urea-formaldehyde resin sii daaya formaldehyde inta lagu jiro habka wax soo saarka iyo isticmaalka. dhibaato, markaa waa in wax laga beddelo.

Codsiga
Waxaa loo isticmaali karaa alaabooyinka aan u baahnayn caabbinta biyaha sare iyo sifooyinka dielectric, sida xargaha korontada, furayaasha, mashiinka mashiinka, daboolka qalabka, burashooyinka, baahiyaha maalinlaha ah, qurxinta, mahjong tiles, daboolka musqusha, iyo sidoo kale waxaa loo isticmaali karaa samaynta alaabta miiska qaarkood.

Xabagta Urea-formaldehyde waa nooca ugu badan ee la isticmaalo ee xabagta. Gaar ahaan soo saarista looxyada macmalka ah ee kala duwan ee warshadaynta alwaaxyada, urea-formaldehyde resin iyo alaabteeda wax laga beddelay ayaa ah qiyaastii 90% wadarta isticmaalka koollada.
