Description

Примен емые при лужении жести сернокислые электролиты не обеспечивают получени  достаточно хорошей структуры осадка олова и не позвол ют регенерировать разбавленный электролит, собирающийс  в отсеке улавливани .The sulphate electrolytes used in tin plating do not provide a sufficiently good structure of tin sediment and do not allow the diluted electrolyte collected in the trap compartment to be regenerated.

Описываемый электролит дл  скоростного лужени  жести с применением серной кислоты, сернокислого олова и органических добавок позвол ет получать осадки высокого качества при высокой интенсивности процесса лужени  и допускает корректирование разбавленного электролита до рабочей концентрации выпариванием при 80-100 Это достигаетс  введением 4,4-тетраметилдиаминдифенилметана в состав электролита .The described electrolyte for rapid tinning of tin with the use of sulfuric acid, tin sulfate and organic additives allows to obtain high quality sludge at a high intensity of tinning process and allows the diluted electrolyte to be corrected to the working concentration by evaporation at 80-100 This is achieved by introducing 4,4-tetramethyldiamine diphenylmethane into the composition electrolyte.

Описываемый электролит содержит: сернокислого олова 40-60 . серной кислоты 75-100 г1л, трилона Б 1-10 г/л, пирокатехина 0,5- 1 г1л и 4,4-тетраметилдиаминдифени.лметана 0,5-3 г/л. Электролиз осуществл ют при плотности тока 20-30 а1дм и температуре электротита 60-80.The described electrolyte contains: tin sulfate 40-60. sulfuric acid 75-100 g1l, trilon B 1-10 g / l, pyrocatechin 0.5-1 gl and 4,4-tetramethyldiamine diphenylmethane 0.5-3 g / l. The electrolysis is carried out at a current density of 20-30 a1 dm and an electrotite temperature of 60-80.

Выход по току составл ет 91% теоретического. Работоспособность электролита - более 50 а-час на каждый литр.The current output is 91% of the theoretical. Electrolyte performance is more than 50 a-hour per liter.

Образующиес  осадки олова легко оплавл ютс . Потери олова не превышают 7%.The tin precipitates that form are easily melted. Losses of tin do not exceed 7%.

Предмет изобретени Subject invention

Электролит дл  скоростного лужени  жести с применением серной , сернокислого олова и органических добавок, отличающийс  тем, что дл  интенсификации процесса лужени  и возможности выпаривани  разбавленного электролита установлен следующий состав электролита: сернокислое олово 40-60 г1л, серна  кислота 75-100 г/л трилон Б 1-10 г/л, пирокатехин 0,5-1 г/л и 4,4-тетраметилдиаминдифенилметан 0,5-3 г/л.The electrolyte for speeding the tin with the use of sulfuric, tin sulfate and organic additives, characterized in that to intensify the process of tinning and the possibility of evaporation of the diluted electrolyte the following electrolyte composition is established: tin sulfate 40-60 g1l, sulfuric acid 75-100 g / l Trilon B 1-10 g / l, pyrocatechin 0.5-1 g / l and 4,4-tetramethyldiamine diphenylmethane 0.5-3 g / l.
