Изобретение относитс к области соединени стекл нных изделий с металлическими и может быть использовано при производстве остеклованных труб в качестве промежуточного сло между стеклом и металлом.The invention relates to the field of joining glass products with metal and can be used in the manufacture of vitrified tubes as an intermediate layer between glass and metal.
Известна эмаль, включающа В2Оз, NagO, SiO2, СоО, NiO, не пригодна дл остекловывани труб.Known enamel, including B2Oz, NagO, SiO2, CoO, NiO, is not suitable for vitrifying pipes.
Целью изобретени вл етс использование эмали в качестве промежуточного сло при остекловывании металлической трубы.The aim of the invention is the use of enamel as an intermediate layer when vitrifying a metal pipe.
Достигаетс это тем, что эмаль содержит следующие компоненты, вес. %:This is achieved by the fact that the enamel contains the following components, weight. %:
В2Оз50 -60B2Oz50 -60
Na2O25 -35Na2O25 -35
NiO0,5- 1NiO0.5-1
SiO25 -15SiO25 -15
СоО1,5- 2CoO1,5- 2
Эмаль состава, вес. %: В2Оз 58; Na2O 30; SiO2 10; СоО 1,5; NiO 0,5 обладает следующими свойствами:Enamel composition weight. %: B2Oz 58; Na2O 30; SiO2 10; Soo 1,5; NiO 0.5 has the following properties:
Коэффициент термического расширени а 10-, 1/°С, в интервале температур 20-400°С.The coefficient of thermal expansion is 10-, 1 / ° C, in the temperature range of 20-400 ° C.
Температура разм гчени , °С 535.Softening temperature, ° C 535.
Величина прочности сцеплени эмали с металлом трубы, кг/мм 8.The magnitude of the adhesion strength of the enamel with the metal pipe, kg / mm 8.
