Obtaining basaltic continuous and staple fibers from rocks in Krasnodar Krai

Abstract

The possibility of using rocks form the Khatsavitskoe, Solokhaul'skoe, and Tugupskoe deposits in Krasnodar Krai in the production of basaltic fibers has been investigated. Using laboratory single-spinneret setup it is shown that continuous, thickened, and rough fibers are formed from melts of these rocks in a wide temperature interval. Using a setup with an induction method of melting the raw materials and acoustic blowing of the melt with compressed air, commercial prototype batches of superthin staple fibers, whose main technical characteristics fall into the range regulated by GOST 4640-93, were obtained.

Suitability of Icelandic basalt for production of continuous fibres

“…The optimal chemical composition for production of CBF is considered to be one that gives an acidity modulus in the range 3–6 (e.g. Tatarintseva and Khodakova 2010, Tatarintseva et al 2012a).…”
