Description

Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 26.10.1974 71838 W- 48a, 1/04 MKP C23b 1/04 1 ^, .- .Twórcawynalazku: Kazimierz Mloczek Uprawniony z patentu tymczasowego: Wojewódzkie Biuro Dokumentacji Technicznej Przemyslu Terenowego,Katowice (Polska) Kapiel do elektrochemicznego odtluszczania i odrdzewiania metali i ich stopów Przedmiotem wynalazku jest kapiel do elektrochemicznego odtluszczania i odrdzewiania metali i ich sto¬ pów.Znane sa kapiele do elektrochemicznego odtluszczania, które w wiekszosci wypadków oparte sa na fosfo¬ ranie trójsodowym, wodorotlenku sodowym i weglanie sodowym. Elektrolity te posiadaja skomplikowany sklad i sa najczesciej opracowywane dla jednego rodzaju metalu co powoduje ograniczenie ich stosowania^ Kapiel do elektrochemicznego odtluszczania wedlug wynalazku stanowi roztwór wodny glukozy w ilos¬ ci 10-300 g/l i wodorotlenku sodowego w ilosci 5-300 g/l oraz srodek utleniajacy powodujacy powstawanie kwasu glukonowego w trakcie procesu odtluszczania. Odtluszczanie za pomoca kapieli wedlug wynalazku pro¬ wadzi sie w znany sposób przy zachowaniu temperatury od20°C do 100°C i gestosci pradu od 0,1 do 20 A/dcm2.Przyklad kapieli: Glukoza 180-200 gA Wodorotlenek sodowy 120-160 g/l Warunki pracy kapieli Temperatura 60-80°C Gestosc pradu 0,2-10 A Kapiel wedlug wynalazku posiada szczególne zastosowanie w przypadku odrdzewiania przedmiotów stalo¬ wych z polaczeniem depasywacji ich powierzchni powodowana powstawaniem kwasu glukonowego z glikozy.Roztwór ten nadaje sie takze do odtluszczania w kielichach i bebnach. PL PLPriority: Application announced: May 30, 1973 The patent description was published: October 26, 1974 71838 W- 48a, 1/04 MKP C23b 1/04 1 ^, .-. Creator of the invention: Kazimierz Mloczek Authorized temporary patent: Provincial Technical Documentation Office of the Local Industry, Katowice (Poland) Bath for electrochemical degreasing and rust removal of metals and their alloys The subject of the invention is a bath for electrochemical degreasing and rust removal of metals and their alloys. There are baths for electrochemical degreasing, which in most cases are based on trisodium phosphorus, hydroxide sodium and sodium carbonate. These electrolytes have a complicated composition and are most often developed for one type of metal, which limits their use. The electrochemical degreasing bath according to the invention is an aqueous solution of glucose in the amount of 10-300 g / l of sodium hydroxide in the amount of 5-300 g / l and Oxidizing agent causing the formation of gluconic acid during the degreasing process. According to the invention, the degreasing process by means of the bath is carried out in a known manner, maintaining the temperature from 20 ° C to 100 ° C and the current density from 0.1 to 20 A / dm2. Example of the bath: Glucose 180-200 gA Sodium hydroxide 120-160 g / l Working conditions of the bath Temperature 60-80 ° C Current density 0.2-10 A The bath according to the invention has a special application in the case of rust removal of steel objects with the combination of depassivation of their surface caused by the formation of gluconic acid from glucose. This solution is also suitable for degreasing in cups and drums. PL PL
