00 ;о Изобретение относитс  к составам стекол дл  производства волокна, в частности непрерывного, которое может быть использовано в качестве ар мирующего материала дл  изготовлени стеклопластиков. Цель изобретени  - обеспечение стабильности процесса формовани  за счет снижени  кристаллизационной способности. Составы стекол приведены в табл.1 Стекло вар т по обычной технологии . Дл  введени  в состав стекла оксидов редкоземельных элементов (РЗЭ) используют отходы горно-рудно промьшшенности. Введение суммы указанных оксидов РЗЭ в количестве менее 5 мас.% вызывает значительное повышение температуры варки стекла (до ) и приводит к частичной кристаллизации образцов стекла при отливке, что ха рактеризует высокую скорость роста кристаллов. Такой состав стекла непригоден дл  получени  стекловолокна . При введении оксидов РЭЗ в количестве более 20 мас.% стекла отлича ютс  повышенной плотностью при умен шенной в зкости, что вызывает рас- слоение стекломассы в процессе ее осветлени . Указанные составы стекол характе ризуютс  в зкостью при формовании 10 - 10 пауз при значительно сниженных температурах верхнего пре дела кристаллизации, что исключает растекание стекломассы по фипьерной пластине, кристаллизацию стекломасс в фильерах и дает возможность примен ть дл  их формовани  стандартные многофильерные сосуды. Свойства стекол приведены в табл.00; o The invention relates to glass compositions for the production of fibers, in particular continuous fibers, which can be used as reinforcing material for the manufacture of glass-reinforced plastics. The purpose of the invention is to ensure the stability of the molding process by reducing the crystallization ability. The compositions of the glasses are given in Table 1. The glass is var t according to conventional technology. To introduce oxides of rare-earth elements (REE) into the glass composition, mining ore wastes are used. The introduction of the sum of the indicated REE oxides in an amount of less than 5 wt.% Causes a significant increase in the glass melting temperature (up to) and leads to a partial crystallization of the glass samples during casting, which characterizes the high crystal growth rate. Such a glass composition is unsuitable for making glass fibers. With the introduction of oxides of REZ in the amount of more than 20 wt.% Of glass, they are characterized by an increased density with a reduced viscosity, which causes stratification of the glass mass during its clarification. These glass compositions are characterized by viscosity during the molding of 10–10 pauses at significantly lower temperatures of the upper crystallization range, which eliminates the spreading of the glass mass on the phiperon plate, the crystallization of the glass mass in the spinnerets and makes it possible to use standard multiphilic vessels for their formation. Properties of glasses are given in table. 2. Такое сочетание в зкостных и кристаллизационных свойств позвол ет формовать его на промьшщенных многофильерных сосудах без применени  искусственного охлаждени . Ни котемпературное формование указанного стекла экономически выгодно из-за пониженного расхода платины на единицу продукции. Уменьшение скорости роста кристаллов вблизи верхнего предела кристаллизации (KV при t - 20°С) способствует большей стабильности процесса формовани  волокна, т.е. снижению кристаллизационной способности . Эффективность от использовани  предлагаемого состава заключаетср в значительном улучшении технологических свойств стекла, позвол ющих получить безобрьшный процесс формовани  волокна при стабильных физико-механических характеристиках получаемого непрерывного стекл нного волокна. Формула изобретени  Стекло дл  стекловолокна, включающее SiO , .l, CeOg, , , , . 4°3 Yb,j,0, отличающеес  тем, что, с целью обеспечени  стабильности процесса формовани  за счет снижени  кристаллизационной способности , оно дополнительно содержит Sm,0 , GdgCj, , , - - Q при следующем соотношении компонентов, мае.%: 45-65 15-25 10-19 0,2-0,8 0,6-2,4 0,3-1,2 0,5-2,0 0,2-0,8 0,3-1,2 0,4-1,6 0,6-2,4 0,25-1,0 0,4-1,6 0,35-1,4 0,5-2,0 0,4-1,62. Such a combination of viscosity and crystallization properties allows it to be molded into industrial multi-filler vessels without the use of artificial cooling. Neither the temperature-forming of said glass is economically advantageous due to the reduced consumption of platinum per unit of production. A decrease in the growth rate of crystals near the upper crystallization limit (KV at t - 20 ° C) contributes to greater stability of the fiber spinning process, i.e. reduce crystallization ability. The effectiveness of the use of the proposed composition lies in a significant improvement in the technological properties of glass, which allows to obtain a smooth process of forming the fiber with the stable physicomechanical characteristics of the continuous glass fiber obtained.
