Tlhaloso ea Sehlahisoa
Urea-formaldehyde resin (UF), eo hape e tsejoang e le urea-formaldehyde resin, ke polycondensation ea urea le formaldehyde tlas'a ts'ebetso ea catalyst (alkaline kapa acidic catalyst) ho theha resin ea pele ea urea-formaldehyde, ebe e theha e ke keng ea qhibiliha. mokgahlelo wa ho qetela o sa kgoneng ho phekoleha tlasa ketso ya sepheko kapa setlatsi. Resin ea thermosetting. Resin e phekotsoeng ea urea-formaldehyde e na le 'mala o bobebe ho feta phenolic resin, e feto-fetoha, e hanyetsana le li-acid tse fokolang le alkali e fokolang, e na le thepa e ntle ea ho kenya letsoho, e hanyetsa ho apara hantle, ebile e theko e tlase. Ke mefuta e mengata e sebelisoang haholo har'a likhomaretsi, haholo-holo ho Ho etsoa ha liboto tse fapaneng tsa maiketsetso indastering ea ho lokisa lehong, resin ea urea-formaldehyde le lihlahisoa tsa eona tse fetotsoeng li etsa karolo ea 90% ea kakaretso ea tšebeliso ea sekhomaretsi. Leha ho le joalo, resin ea urea-formaldehyde e bonolo ho bola ha e pepesehetse li-acid tse matla le alkalis. E na le khanyetso e mpe ea boemo ba leholimo, viscosity e fokolang ea pele, ho honyela ho hoholo, brittleness, ho hanyetsa metsi, le ho tsofala ha bonolo. Maboto a maiketsetso a hlahisoang ka urea-formaldehyde resin e lokolla formaldehyde nakong ea tlhahiso le ts'ebeliso. bothata, kahoo e tlameha ho fetoloa.
