Description
При электролитическом цинковании в щелочных электролитах нл катоде,, как правило, образуютс отложен 1 губчатого цинка. Основной причиной образовани цинковой губки вл етс накопление в цинкатном электролите мельчайших коллоидных частиц цинка или его соединений, образующихс при анодном растворении цинка. Дл предотвращени этих влений при электролитическом цинковании в щелочных электролизах примен ют цианиды и специальные добавки.When electrolytic galvanizing in alkaline electrolytes on a cathode, as a rule, 1 spongy zinc is deposited. The main reason for the formation of zinc sponge is the accumulation in the zinc electrolyte of the smallest colloidal particles of zinc or its compounds formed during the anodic dissolution of zinc. In order to prevent these phenomena, cyanides and special additives are used in electrolytic galvanizing in alkaline electrolysis.
Предложенный сиособ электролитического цинковани позвол ет получать плотные, мелкозернистые и светлые цинко1зые осадки бе.-i применени цианидов дл щелочных ваин цинковаии .The proposed electrolytic zinc method allows to obtain dense, fine-grained and light zinc precipitation, i.e., the use of cyanides for alkaline wain zinc.
Отличительна особенность способа состоит в том, что в анод ввод т свинец в количестве не более 0,5%, в электролит Ц1;нковаии погружают полоски свинца или перед цинкованием покрывают катод тонким слоем свинца.A distinctive feature of the method is that lead in an amount of not more than 0.5% is injected into the anode, in lead electrolyte C1, the strips are immersed in lead or coated with a thin layer of lead before galvanizing.
Описываемый способ позвол ет устранить образование цинковой губки на катоде, так как каллоидные частицы циика, образующиес при анодном растворении цинка и вызывающие по вление местных губчатых наростов на катоде, контактно вытесн ют свипец из раствора и, окисл сь, переход т в раствор в виде ионов.The described method allows to eliminate the formation of zinc sponge on the cathode, since the calloid particles formed during the anodic dissolution of zinc and cause the appearance of local spongy growths on the cathode, contact the solvent from the solution and, being oxidized, go into solution in the form of ions .
Предмет изобретени Subject invention
. Способ электролитического цинковани в И1елочных электролитах , отличающийс тем, что в электро,тит щитковаии погружают полоски свинца.. A method of electrolytic galvanizing in electrolytic electrolytes, characterized in that strips of lead are immersed in electrical titanium.
2. Видоизменение способа по п. 1, отличающеес тем, что вместо погружени s электролит свинцовых полосок катод перед ци-нкованием покрывают тонким слоем свинца.2. Modification of the method according to claim 1, characterized in that instead of immersing the electrolyte of lead strips, the cathode is coated with a thin layer of lead before chiseling.
3. Видоизменение способа по пп. 1 ц 2, отличающеес тем, что свинец ввод т в аиод в количестве не более 0,3%.3. Modification of the method according to paragraphs. 1 c 2, characterized in that lead is introduced into the iodine in an amount of not more than 0.3%.
