Abstract

SYNOPSIS IN INTERLINGUA CHARACTERISATION DEL PROCESSO DEL PRISA IN CAUCHUS DENTAL A POLYSULFURO.—Le characteristicas del prisa de cauchus dental a polysulfuro esseva studiate per viscometria extrusional. Quando le reagente de prisa esseva addite, le fortia extrusional (F) cresceva exponentialmente con le tempore, i.e., F = Aexp(kt). Per contrasto con le situation in alginatos e cauchus a silicona, nulle prestemente identificabile tempore del initiation del processo de prisa esseva trovate. Le parametro k characterisava le intensitate del prisa. Illo dependeva del temperatura, e le energia de activation esseva circa 12 kilo-calorias per mol. Le parametro k esseva relativemente insensibile pro le concentration del reagente de prisa. Isto contrastava marcatemente con le comportamento de cauchus a silicona. Le characteristicas del processo de prisa es explicabile a bases chimic.
