20.500.12556/DKUM-56228 The influence of physico-chemical parameters on water scale precipitation on washing machines' heaters 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. 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. magnetic water treatment magnetic hydrodynamics water scale calcium carbonate scale prevention washing machine electrical heater magnetna obdelava vode magnetna hidrodinamika vodni kamen usedline preprečevanje vodnega kamna kalcijev karbonat pralni stroji električni grelec true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-12-21 16:53:25 2015-12-21 16:53:25 2022-06-11 03:08:49 2021-05-15 03:29:34 2007 0 0 str. 719-724 št. 4 Letn. 54 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 628.162:537.84 14086149 12003862 1318-0207 URN:SI:UM:DK:BNUCUBGE Acta_Chimica_Slovenica_2007_Dobersek,_Goricanec,_Krope_The_influence_of_physico_-_Chemical_parameters_on_water_scale_precipitation_on_wa.pdf Acta_Chimica_Slovenica_2007_Dobersek,_Goricanec,_Krope_The_influence_of_physico_-_Chemical_parameters_on_water_scale_precipitation_on_wa.pdf 1 C86857D1662B8A0DFE476A9F355C1DC2 ee64d5db29a14dbaf7ec65494fa6679016b43de553fef61fb48587a693a285dd 936100d2-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=116289 http://acta-arhiv.chem-soc.si/54/54-4-719.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=84361 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
