Fa'amatalaga o oloa

Urea-formaldehyde resin (UF), lea e lauiloa foi o le urea-formaldehyde resin, o le polycondensation o le urea ma le formaldehyde i lalo o le gaioiga a le catalyst (alkaline poʻo le acidic catalyst) e fausia ai se uluaʻi urea-formaldehyde resin, ona fausia ai lea o se mea e le mafai ona faʻaaogaina. infusible vaega mulimuli i lalo o le gaioiga a se vailaʻau faʻamalolo poʻo faʻaopoopoga. Thermosetting resin. O le resini urea-formaldehyde faʻamalolo e mama i le lanu nai lo le resini phenolic, translucent, faʻasaʻo i vai vaivai ma vaivai alkali, e iai mea faʻapipiʻi lelei, faʻaofuofu lelei, ma taugofie. O le ituaiga sili ona masani ona faʻaaogaina i totonu o mea faʻapipiʻi, aemaise lava i le gaosiga o laupapa faʻapitoa eseese i le gaosiga o fafie, urea-formaldehyde resin ma ana oloa faʻaleleia e tusa ma le 90% o le aofaʻi o le faʻaogaina o le pipii. Ae ui i lea, o le urea-formaldehyde resin e faigofie ona pala pe a faʻaalia i vailaʻau malolosi ma alkalis. E le lelei le tau, le lelei o le viscosity muamua, fa'aitiitia tele, fa'afefeteina, fa'afefe vai, ma le matua faigofie. O laupapa fa'akomepiuta e gaosia i le urea-formaldehyde resin e fa'asa'o ai formaldehyde i le taimi o le gaosiga ma le fa'aogaina. fa'afitauli, o lea e tatau ai ona toe fa'aleleia.

Fa'atatauga

E mafai ona faʻaaogaina i oloa e le manaʻomia ai le maualuga o le vai ma mea faʻaeleʻele, e pei o le eletise, ki, masini masini, meafaifaʻaili, ki, mea e manaʻomia i aso uma, teuteuga, tile mahjong, tapuni faleuila, ma e mafai foi ona faʻaaogaina i le gaosiga o nisi laulau.

Urea-formaldehyde resin o le ituaiga sili ona faʻaaogaina o mea faʻapipiʻi. Aemaise lava i le gaosiga o laupapa faʻapitoa eseese i le gaosiga o fafie, urea-formaldehyde resin ma ana oloa faʻaleleia e tusa ma le 90% o le aofaʻi o le faʻaogaina o le pipii.
