Description

Изобретение относится к производству эмали для покрытия, преимущественно, стальных и чугунных изделий. The invention relates to the production of enamel for coating mainly steel and cast iron products.

Известна эмаль, включающая следующие компоненты, мас.%: SiO2 68,74-72,72; Na2O 9,63-10,82; K2O 5,5-6,53; Li2O 2,5-3,41; SrO 9,65-10,5 (1). Ударная прочность такой эмали 12-14 Дж.Known enamel, comprising the following components, wt.%: SiO 2 68,74-72,72; Na 2 O, 9.63-10.82; K 2 O 5.5-6.53; Li 2 O 2.5-3.41; SrO 9.65-10.5 (1). Impact strength of such enamel is 12-14 J.

Достигаемым техническим результатом является повышение ударной прочности эмали. Achievable technical result is to increase the impact resistance of enamel.

Указанный технический результат достигается тем, что эмаль содержит следующие компоненты, мас.%: SiO2 61,0-63,5; Na2O 7,0-9,0; K2O 7,0-8,5; Li2O 1,5-2,0; SrO 9,0-10,0; NiO 7,5-8,5; FeO 2,0-4,0.The specified technical result is achieved in that the enamel contains the following components, wt.%: SiO 2 61.0-63.5; Na 2 O 7.0-9.0; K 2 O 7.0-8.5; Li 2 O 1.5-2.0; SrO 9.0-10.0; NiO 7.5-8.5; FeO 2.0-4.0.

В таблице приведены конкретные составы предложенной эмали. The table shows the specific compositions of the proposed enamel.

Ударная прочность предложенной эмали составит 20-22 Дж для всех составов. Увеличение ударной прочности повышает надежность эмалевого покрытия, увеличивает срок службы эмалированных изделий. Impact strength of the proposed enamel will be 20-22 J for all compositions. The increase in impact strength increases the reliability of the enamel coating, increases the service life of enameled products.
