Vpliv dodatkov na lastnosti sulfoniranih melaminsko-formaldehidih pen

Petrič, Lucija (author), Alič, Branko (mentor)

Pripravila sem 15 različnih SMF pen, na podlagi spreminjanja mas osnovnih komponent pene in dodatkov. Tako sem ugotavljala kako določene snovi in dodatki vplivajo na lastnosti SMF pen. Vsako peno sem pripravila po istem postopku. Zamreževanje je potekalo v mikrovalovni pečici. Izmerila sem njihove mehanske lastnosti, njihovo gostoto ter ugotavljala njihovo mikroskopsko zgradbo.

• Title: Effect of additives on characteristics sulfonated melamine formaldehyde foams

Abstract

I prepared 15 different SMF foams with different mass of basic component of foams and additives. By changing their ratios I tried to determine how certain component and additives effect on characteristics of SMF foams. All foams were prepared by the same procedure. Crosslinking proceeded in microwave. I measured their mechanical properties, their density and observe their microscopic structure.
