Utekočinjen les in njegova uporaba

Abstract

Opisani so postopki pridobivanja utekočinjenega lesa pri normalnem tlaku in povišani temperaturi. Najpomembnejša sta utekočinjenje s polihidričnimi alkoholi in utekočinjenje s fenolom. Oba postopka zahtevata uporabo katalizatorjev, ki se lahko med seboj zelo razlikujejo. Kombinacija utekočinjenega lesa in predvsem umetnih smol vodi do nastanka novih fenolnih in epoksi smol ter do sedaj nepoznanih poliuretanskih pen.

Secondary title:	Liquefied wood ands its application
Secondary abstract:	Described are procedures of liquified wood production at normal pressure and higher temperatures. The most important ones are liquifieing with polyhidric alcohols and liquifieing with phenol. Both procedures demands us-age of different catalysators. Combination of liquified wood and resins leads us to forming new phenol and epoxi resins and up to now unknown polyurethanic foames.
