Description
Изобретение относитс к области наЬ несени покрытий.This invention relates to the field of coating application.
Известен состав дл пассивировани цинка содержащий соединени трех- и шестивалентного хрома.A known composition for passivating zinc containing compounds of trivalent and hexavalent chromium.
Предложенный состав отличаетс тем, что в него введены соль азотной кислоты и борсодержащее соединение при определенном соотношении компонентов, причем со.пь азотной кислоты и борсодержащее соединение выбрацны соответственно из группы, содержащей нитраты аммони щелочного металла берили , магни , цинка и кадми р и из группы, содержащей борную кислоту, борат магни и полибораты аммони , щелочного металла , берили и магни . Это повышает коррозионную стойкость покрыти .The proposed composition is characterized in that a nitric acid salt and a boron-containing compound are added to it at a certain ratio of components, and the nitric acid copolymer and boron-containing compound are selected, respectively, from the group containing ammonium alkali metal nitrates of beryl, magnesium, zinc and cadmium p and from containing boric acid, magnesium borate, and ammonium, alkali metal, beryl, and magnesium polyborates. This increases the corrosion resistance of the coating.

Оптимальное содержание соединений трех- и шестивалентного хрома 1в пересчете на хром), соли азотной кислоты (в пересчете на MOj ) и борсодержащего соединени (в пересчете на бор) составл ет соответственно 10,0; 0,5; 17,8 и 4,3%. The optimum content of compounds of trivalent and hexavalent chromium 1 in terms of chromium), salts of nitric acid (in terms of MOj) and boron-containing compound (in terms of boron) is respectively 10.0; 0.5; 17.8 and 4.3%.
В качестве соединени трехвалентного хрома используют соединени изAs compounds of trivalent chromium, compounds from
ГРУППЫ, содержащей сульфат и нитрат хрома, хромовые квасцы. В качестве соединени шестивалентного хрома используют соединени из группы, -содержащий хромовую кислоту и бихроматыGROUPS containing chromium sulfate and nitrate, chromic alum. As a compound of hexavalent chromium, compounds from the group, -containing chromic acid and bichromates are used.
аммони , щелочного металла, берили , магни , цинка и кадми .ammonium, alkali metal, beryl, magnesium, zinc and cadmium.
Процесс пассивировани осуществл ют следующим образом.The passivation process is carried out as follows.
Приготавливают пассивирующий состав тщательным смешиванием его компонентов до образовани однородной массы. Затем 20-60 г полученной массы раствор ют в 1 л дистиллированнойThe passivating composition is prepared by thoroughly mixing its components until a homogeneous mass is formed. Then, 20-60 g of the obtained mass is dissolved in 1 liter of distilled
или деионизованной воды. Издели с цинковой поверхностью обрабатывают пассивирующим раствором в течение го-laa (оптимально 30 сек) при 15-35С (оптимально 25QC) . Наноситьor deionized water. Products with a zinc surface are treated with a passivating solution for th-laa (optimally 30 seconds) at 15-35 ° C (optimally 25QC). Apply
