Description
(54) СУСПЕНЗИЯ ДЛЯ ПОЛУЧЕНИЯ ЭЛЕКТРОИЗОЛЯЦИОННБ1Х ЖАРОСТОЙКИХ ПОКРБ1ТИЙ(54) SUSPENSION FOR OBTAINING ELECTRO-INSULATING HEAT-RESISTANT BOXES
Таблица 1Table 1
Суспензию нанос т на нолосы трансформаторной стали с помощью профилированных роликов и покрытие высушивают при 180- 200°С в индукторе. Суспензию готов т путем смешени окиси магни с водой до однородной консистенции и затем добавлени в смесь соли магни либо путем добавлени к смеси окиси магни и воды необходимого количества муравьиной или уксусной кислот дл образовани муравьинокислого или уксуснокислого магни . Дл приготовлени суспензии в качестве частично гидратируюш;ейс окиси магни используетс и окись магни со степенью гидратации 20 и 63%. Результаты проведенных исследований при различном составе суспензии приведены в табл. 1.The suspension is applied to the nolos of transformer steel with the help of profiled rollers and the coating is dried at 180-200 ° C in an inductor. The slurry is prepared by mixing the magnesium oxide with water to a uniform consistency and then adding the magnesium salt to the mixture or by adding the required amount of formic or acetic acid to the mixture of magnesium oxide and water to form formic acid or magnesium acetate. To prepare the suspension as partially hydrated, magnesium oxide is used to use magnesium oxide with a degree of hydration of 20 and 63%. The results of the studies with different composition of the suspension are given in table. one.

Адгези покрыти к стали Adhesion to steel
оцениваетс в баллах:Scored:
1 - адгези отсутствует,1 - no adhesion,
5 - адгези высока ,5 - high adhesion,
2-4 - промежуточные значени адгезии.2-4 are intermediate adhesion values.
Как видно из таблицы, даже при минимальном количестве вводимой соли магни 0,4% (композици 1) адгези повышаетс по сравнению с суспензией, не содержащей этой соли (композици И). Адгези имеет наибольшее значение при содержании муравьинокислого магни 4,8% (композици 4) и уксуснокислого магни 15,2% (композици 8). При этом при использовании суспензии, содержащей муравьинокислый магний, в большей степени возрастает не только адгези покрыти к металлу, но и его электрическое сопротивление (см. табл. 2, в которой представлена характеристика покрытий, полученных из предложенной и известной суспензий, а также магнитных свойств трансформаторной стали толщиной 0,28 мм после высокотемпературного отжига).As can be seen from the table, even with a minimum amount of magnesium salt of 0.4% (composition 1), adhesion is increased compared with a suspension that does not contain this salt (composition I). Adhesion is most important when the content of magnesium formate is 4.8% (composition 4) and magnesium acetate with 15.2% (composition 8). In this case, when using a suspension of magnesium formic acid, not only does the adhesion of the coating to the metal increase, but also its electrical resistance (see Table 2, which describes the characteristics of the coatings obtained from the proposed and known suspensions, as well as transformer steel with a thickness of 0.28 mm after high-temperature annealing).
Как видно из данных таблицы 2, использование предложенной суспензии не только улучшает адгезию покрыти , но и магнитные свойства стали.As can be seen from the data of Table 2, the use of the proposed suspension not only improves the adhesion of the coating, but also the magnetic properties of the steel.
