Description

(54) РАСТВОР Да очистки ПОВЕРХНОСТИ ЧЕРНЫХ МЕТАЛЛОВ(54) SOLUTION FOR SURFACE BLACK METAL SURFACE

Изобретение относитс к области химической обработки поверхности металпов, в частности созданию раствора дп очистки поверхностей черных металлов от ржавчины и жировых загр знений.The invention relates to the field of chemical treatment of the surface of metals, in particular the creation of a solution dp of cleaning surfaces of ferrous metals from rust and fatty contaminants.

Известен раствор, содержащий ортофосфорную кислоту - 15-3 О г/л и синтаноп ДС-10 г/п ij. Известный раствор эффективен при температурах выше 20-25 С.A known solution containing orthophosphoric acid - 15-3 O g / l and sintanop DS-10 g / n ij. Known solution is effective at temperatures above 20-25 C.

Недостатком известного р аствора ап етс низкое обезжиривающее действие.A disadvantage of the known solution is a low degreasing effect.

Цепь изобретени - создание раствора, который позвол ет повысить качество травлени металлов за счет одновременного удалени ржавчины и жировых загр знеНИИ , а также улучшени адгезии лако 1фасочных покрытий.The chain of the invention is the creation of a solution that improves the quality of metal etching due to the simultaneous removal of rust and fatty contaminants, as well as improving the adhesion of paint coatings.

Это достигаетс тем, что раствор дополнительно содержит сульфосапициловую кислоту, аммоний азотнокислый иThis is achieved in that the solution additionally contains sulfosapicylic acid, ammonium nitrate and

Claims

Example. An aqueous solution is prepared for treating the surface of ferrous metals for color, including orthophosphoric acid (6%), sulfanol (2 g / l), sulfosalicylic acid (2 g / l), ammonium nitrate (4 g / l) and acetone (8 %). 362 The surface of the edepi running gear is treated with the prepared solution. The surface of the parts has slash contamination with teeshichnyh oils and e 4u: P1lopom and atmospheric corrosion. As a result of sea trials, it was found that there was no evidence of delamination of paint and varnish coating on the test parts, which indicates significant improvement in adhesion. The treated surface also needs a d: reprocessing treatment for the removal of rust. The solution for preparing the surface of the hard metals for painting is non-toxic and non-fire hazardous, allows simultaneous removal of rust and gilts, and does not require subsequent washing with water. The solution helps to increase the productivity of work, to process surfaces with a rubbing, dipping, and a jet region. 84 Formula of the invention Solution dp of cleaning the surface of ferrous metals, including phosphoric acid and surfactant, characterized in that, with a chain of improved quality of cleaning, it additionally contains sulfosalicylic acid, ammonium nitrate and acetone in the following ratio of components, g / l: Orthophosphoric acid (sp.
