(54)-СМЕСЬ ДЛЯ ПРОЯВЛЕНИЯ МАГНИТНОЙ ЗАПИСИ(54) -MIX FOR MANIFESTATION OF MAGNETIC RECORDING

Claims (1)

Изобретение огносигс  к технике магнитной записи, а именно к про вл ющим смес м. Известен про вигепь магнитной записи на основе предварительно намагниченного магнитного порошка lj. Однако такой про витель прит гивает с  к элементам аппаратуры магнитной записи. Наиболее близкой кiизобретению  вл  етс  смесь дл  про влени , содержаща  карбонильное железо и бензин 2j. Недостатком этой смеси  вл етс  мала  адгезионна  способность, снижающа  прочность про вл ющего сло . Целью изобретени   вл етс  повышени адгезионной способности. Дл  этого в смесь, содержащую карб1 нипьное железо и бензин, дополнительно введена канифоль при следующем соотношении ингредиентов, вес. %: Карбонильное железо 2 - 2,5 Бензин ,91,5-94 Канифоль4 - 6 При приготовлении смеси в 93 вес.% бензина были введены 2 вес. % карбонильного жепеза и 5 вес. % канифоли. Смесь нанос т на магнитный носигепь. Высыхание смеси продолжаетс  2 мин, после чего на поверхности носител  о&разуетс  пленка про вител . Удаление пленки про вител  производитс  чистым бензином. Предлагаема  смесь позвол ет получить четкое изображение, про вл юща  пленка эластична и не разрушаетс  при пр косновешга и перегибах ленточного носител  , не разрушает магнитный носитель и ив загр зн ет аппаратуру. Формула изобретени  Смесь дл  про влени  магнитной аапкси , содержаща  карбонильное железо и бензин, отличающа с  тем, что, с целью повышени  адгезионной способности, в нее дополнительно введена канифоль при следующем соотношении ингредиентов, вес. %:The invention of ognosigs to the technique of magnetic recording, in particular, to developing mixtures. It is known to record magnetic recordings on the basis of a pre-magnetized magnetic powder lj. However, such an vendor attracts with to the elements of magnetic recording equipment. Closest to the invention is a mixture for the manifestation, containing carbonyl iron and gasoline 2j. The disadvantage of this mixture is low adhesiveness, which reduces the strength of the developing layer. The aim of the invention is to increase the adhesion ability. To do this, rosin is additionally added to the mixture containing carbide iron and gasoline with the following ratio of ingredients, weight. %: Carbonyl iron 2 - 2.5 Gasoline, 91.5-94 Rosin4 - 6 When preparing the mixture, 93% by weight of gasoline was introduced 2 weight. % carbonyl zhepeza and 5 wt. % rosin. The mixture is applied to a magnetic nasigap. Drying of the mixture lasts 2 minutes, after which a pro ducer film is formed on the surface of the carrier. Removal of the film is made by pure gasoline. The proposed mixture allows to obtain a clear image, the developing film is elastic and does not break when the carrier bends and bends the tape, does not destroy the magnetic carrier and also contaminates the equipment. Claims of the invention Magnetic aapxy mixture containing carbonyl iron and gasoline, characterized in that, in order to increase the adhesiveness, rosin is added to it in the following ratio of ingredients, weight. %: 3622128436221284 Карбонильное железо 2-2,51.
