Description
Известные способы удалени задублениого сло с новерхмости биметаллических форм офсетной печати трудоемкие и требуют специальных условий дл работы.Known methods for removing the zubilne layer from the top of the bimetallic forms of offset printing are labor intensive and require special conditions for operation.
Предлагаетс способ удалени задубленного сло с (|)орм при помощи электрохимической обработки.A method for removing a pitted layer with (|) orms using electrochemical treatment is proposed.
Форма (см. чертеж) завешиваетс в гальваническую ваниу и вл етс катодом. В качестве анода может быть использован корпус ванны или отдельные аноды. Электролитом вл етс слабый раствор сол ной кислоты; плотность тока равна 5 нродолжителыюсть нроцесса 5-6 мин.The form (see drawing) is hung in vanilla and is the cathode. The body of the bath or individual anodes can be used as the anode. The electrolyte is a weak solution of hydrochloric acid; current density is equal to 5 cycles of 5–6 min.
Выдел ющийс на катоде (на обрабатываемой форме) атомарны; водород своим давлением в момент выделени отрывает пленку задубленного сло .Separated at the cathode (on the processed form) are atomic; Hydrogen, with its pressure at the moment of release, tears off the film of the zadubated layer.
Предлагаемый способ более рационален и исключает примепе.тме трудоемкого ручного труда.The proposed method is more rational and excludes the use of labor-intensive manual labor.
Предмет изобретени Subject invention
Способ удалени задубленного сло с поверхности плоских биметаллических форм офсетной печати путем воздействи на него водных растворов неорганических соединений, о т л и ч а ю HI ийс тем, что. с нелью интенсификации нроцесса и устранени ручного труда, обработку форм производ т электролитически, включа их в качестве катодов, и примен в качестве электролита слабый раствор сол ной кис.кггы, причем плотность тока поддерживают примерпо 5 а/дм-.The method of removing a zabublennogo layer from the surface of flat bimetallic forms of offset printing by exposing it to aqueous solutions of inorganic compounds, so that. With the aim of intensifying the process and eliminating manual labor, the forms are processed electrolytically, including as cathodes, and a weak solution of hydrochloric acid is used as the electrolyte, the current density being approximately 5 a / dm.
