Abstract

Razvlaknjenje taline mineralne volne je kompleksen proces, katerega poznavanje je ključnega pomena pri proizvodnji izolacijskih materialov. Postavili smo preizkuševališče, ki omogoča proučevanje procesa razvlaknjenja. Pomembni vhodni parametri, ki vplivajo na proces, so vrtilna frekvenca koles centrifuge, položaj natoka in volumski pretok taline. Izdelali smo regresijski model izkoristka razvlaknjenja taline v odvisnosti od vhodnih parametrov. Z opazovanjem procesa s hitro kamero je bila ugotovljena neenakomerna gostota porazdelitve vlaken na zbiralni mreži v odvisnosti od vhodnih parametrov.

Secondary title:	Model of melt fiberization on a two wheel spinner
Secondary abstract:	Melt fiberization is a complex process and its understanding is crucial for production of insulating materials. A measurement setup has been designed to allow the study of important input parameters that influence the fiberization process such as wheel rotational speed, angular position of the melt and the melt volume flow. A regression model of melt fiberization efficiency was made based on the input parameters. By visualization of the fiberization process with a high-speed camera, an uneven density of fiber distribution on the collecting grid was determined depending on the input parameters.
