Abstract

The paper presents the results of analysis of physico - chemical parameters influence on the intensity of water scale precipitation on washing machines heaters. Washing machines of the same producer were, to this end, modified to an endless cycle of washing with the same amount of cotton fabric at the same conditions. On the basis of various experiments it was determined that water hardness, the amount of exceeded carbon dioxide, water turbulence around the heater, the amount of cotton fibres in water exceeded from fabrics, and heater specific heat strength have the key role in water scale building up in washing machines heaters.

Secondary abstract: V prispevku so podani rezultati analize vpliva fizikalno kemijskih parametrov na intenzivnost izločanja vodnega kamna na grelcih pralnih strojev. Pralni stroji istega proizvajalca so bili v ta namen posebej prirejeni na neskončen cikel pranja z isto količino bombažnih tkanin pri istih pogojih. Na osnovi več različnih eksperimentov je bilo ugotovljeno, da imajo ključno vlogo pri nalaganju kamna na grelce pralnih strojev trdota vode, količina presežnega ogljikovega dioksida, turbulenca vode okoli grelca, količina iz tkanin izločenih bombažnih vlaken v vodi in specifična grelna moč grelca.
