Изобретение относитс к составам химически стойких стекол дл внутреннего остекловывани металлических труб.This invention relates to chemically resistant glass compositions for the internal vitrification of metal tubes.
Известно химически стойкое стекло fl включающее, вес.%: SiOj 6075; Г -2.0 до 5; МдО 2-5; СаО 3-1р; SrO 0,2-1,8; BjO 2-5; TiOi 0,2-1,8. Это стекло по химической устойчивости относитс к 1-му гидролитическому классу и обладает температурой оплавлени выше .Known chemically resistant glass fl including, wt.%: SiOj 6075; G -2.0 to 5; MDO 2-5; CaO 3-1p; SrO 0.2-1.8; BjO 2-5; TiOi 0.2-1.8. This glass is chemically resistant to the 1st hydrolytic class and has a higher melting point.

Стекло характеризуетс хорошими химическими и . термическими свойствами.Chemically resistant glass 2, composition, wt.%: SiO, is closest to the proposed one. 53-71, AIzO, 4.5-10; BiOa 5-10; CaO 3.2-6; MgO 0.1-2.1, N32.0 5-8; KjO 0.1-2; BaO 0.5-10; SrO 0.5-10. Glass is characterized by good chemical and. thermal properties.
К недостаткам известных стекол относ тс мала смачивающа и адгезионна способность к стали, низкие значени КЛТР и высокие температуры оплавлени (вьпле 800 С) .The disadvantages of the known glasses are low wetting and adhesive ability to steel, low CTE values and high melting temperatures (800 C).
Цель изобретени - увеличение смачивающей и адгезионной способности к стали.The purpose of the invention is to increase the wetting and adhesive ability of steel.
