Abstract
Изобретение относится к физико-механохимическим процессам переработки избирательных видов отсевов гранитного производства путем технологии получения минерального волокна на основе шихты горных пород с производством из нее силикатных расплавов с последующим раздувом размерных или бесконечных волокон или нитей. Технический результат изобретения характеризуется механоактивацией сырьевой смеси до полной гомогенизации как смеси шихты, так и расплава. Способ производства минеральных волокон включает шихтовку компонентов, образованных из отходов производства горнорудной продукции на основе гранитоидных пород, плавление с последующим раздувом из расплава волоконной нити, при этом компоненты шихты вводят в виде отсевов основного щебеночного производства в составе гранитоидных пород и метадиабазов, с содержанием петрогенных окислов, сопоставимых с базальтами и андезибазальтами субщелочного ряда, при этом механоактивируют компоненты шихты фракцией от 0,0001 до 160 мкм с числом Fr-(Фруда) не менее 6-9 в течение 30-90 с и осуществляют гомогенизацию путем смесеобразования с содержанием компонентов, мас.%: диориты - 64-79%, граниты - 10-13%, гранодиориты - 6,3-8,5%, метадиабазы - 4,3-6,4%, и начинают плавку не позже чем через 60-3600 с непосредственно после механоактивации при 1050-1150°C с последующим раздувом из расплава волоконной нити.The invention relates to physical and mechanochemical processes for processing selective types of screenings of granite production by the technology of obtaining mineral fiber based on a mixture of rocks with the production of silicate melts from it with subsequent blowing of dimensional or endless fibers or threads. The technical result of the invention is characterized by mechanoactivation of the raw mixture until complete homogenization of both the mixture of the charge and the melt. The method for the production of mineral fibers includes the mixing of components formed from waste products of mining products based on granitoid rocks, melting and subsequent blowing from the melt of a fiber thread, while the components of the batch are introduced in the form of screenings of the main crushed stone production as part of granitoid rocks and metadiabases, containing petrogenic oxides , comparable with basalts and basaltic andesites of the subalkaline series, while mechanically activating the components of the charge with a fraction of 0.0001 to 160 μm with a Fr- (Froude) number of at least 6-9 for 30-90 s and homogenization is carried out by mixing with the content of components, wt .%: diorites - 64-79%, granites - 10-13%, granodiorites - 6.3-8.5%, metadiabases - 4.3-6.4%, and start melting no later than 60-3600 s immediately after mechanical activation at 1050-1150 ° C, followed by melt blowing of the fiber thread.
