The fibers were pneumatically transported from the spinner rotor to the accumulation grid with the aid of the blow-away and the suction airflow. The fiber primary layer formed on the accumulation grid was visualized by a camera for several different operating regimes. Acquired images were post-processed to determine the light absorption in the primary layer, which was then used to calculate the bulk density and the surface density of the layer. Based on the measured process quantities, we were able to form multiple regression models with a relatively good correlation to the experimental data. The models as well as the qualitative image analysis show a significant effect of spinner rotor rotational speed, pneumatic transport velocity and fiber deposit mass on primary layer bulk density and spatial distribution of fibers"},{"@xml:lang":"sl","#text":"V proizvodnem procesu mineralne (steklene, kamene) volne je faza tvorbe primarne plasti vlaken izrednega pomena za lastnosti in kakovost končnih proizvodov.

Pojav je zelo kompleksen, saj gre za dvofazni tok zrak-vlakna, za katerega so značilne zapletene prostorske strukture medsebojno prepletenih vlaken, ki so v interakciji s turbulentnim tokom odpiha. Zaradi kompleksnosti procesa in težavnih pogojev za opazovanje je ravno tvorba primarne plasti najslabše raziskan sklop v proizvodni verigi mineralne volne"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-OB9BM9L0","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-OB9BM9L0"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-OB9BM9L0/022dc402-6f93-42b8-bae1-b62589c52682/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-OB9BM9L0/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-OB9BM9L0"}}}}
