Изобретение ОТРШСИТСЯ к составам дл очистки металлической поверхности от высокотемпературных отложений, а именно отложений, образующихс в особых услови х (высока температура при одновременном воздействии песка, глины и топлива).The invention will refer to compositions for cleaning a metal surface from high-temperature deposits, namely deposits that are formed under special conditions (high temperature with simultaneous exposure to sand, clay and fuel).
Цель изобретени - интенсификаци процесса и улучшение качества очистки.The purpose of the invention is to intensify the process and improve the quality of cleaning.
Состав г.отов т последовательным смешением всех компонентов при подогревании .The composition of the graves is the sequential mixing of all the components when heated.
Режим обработки деталей: температура 140-150 С, врем очистки 40 60 мин; затем следует промывка деталей в° кислотном растворе с добавками трех- и шестивалентного хрома.The mode of processing details: temperature 140-150 C, cleaning time 40–60 min; This is followed by washing the parts in ° acidic solution with additions of tri- and hexavalent chromium.
Дл испытаний приготовлены три .раствора следующего состава, г/л:For the tests prepared three solutions of the following composition, g / l:
1.Едкий натр 400 Нитрит натри 50 Нитрат натри 10 Калий-цирконий фтористый3 Вода До 1 л1.Sodium soda 400 Nitrite sodium 50 Sodium nitrate 10 Potassium-zirconium fluoride3 Water Up to 1 l
2.Едкий натр 550 Нитрит натри 100 Нитрат натри 30 Калий-цирконий фтористый«4 Вода До 1 л2. Edible soda 550 Nitrite sodium 100 Sodium nitrate 30 Potassium-zirconium fluoride “4 Water Up to 1 l
3.Едкий натр 700 Нитрит натри 200 Нитрат натри 503. Edible soda 700 Nitrite sodium 200 Nitrate sodium 50
- Калий-цирконий- Potassium Zirconia
Результаты испытаний приведены в .таблице,The test results are given in the table.
Врем полной очистки деталей в предлагаемой композиции составл ет 40-60 мин, тогда как в известном растворе даже после обработки в течение 80-120 мин отложени удал ютс лишь на 85-95%. .The time of complete cleaning of parts in the proposed composition is 40-60 minutes, whereas in a known solution, even after treatment for 80-120 minutes, the deposits are removed only by 85-95%. .
Предлагаемьш состав позвол ет достичь полной очистки деталей от высокотемпературных отложений за более короткое врем , что дает возможность увеличить производительность процесса очистки в 1,5 раза, существенно улучшив при этом качество очистки деталей .The proposed composition allows to achieve complete cleaning of parts from high-temperature deposits in a shorter time, which makes it possible to increase the productivity of the cleaning process by 1.5 times, while significantly improving the quality of cleaning of parts.
