Description
Przedmiotem wynalazku jest sposób obróbki po¬ wierzchni strony nieuzytkowej blach chemigraficz¬ nych przed lakierowaniem.The subject of the invention is a method of treating pores the face of non-usable chemigraphic sheets before painting.
W przemysle poligraficznym do otrzymywania form drukowych jako podloze stosuje sie najczes¬ ciej metalowe blachy chemigraficzne, korzystnie cynkowe. Na szlifowana powierzchnie tych blach nanosi sie warstwe swiatloczula, która naswietla sie przez negatyw. Elementy naswietlone zostaja przez swiatlo zahaftowane i traca swoja rozpusz¬ czalnosc w wodzie, natomiast elementy nienaswie- tlone usuwa sie odslaniajac w tych miejscach pod¬ loze metalowe. Pozostale na blasze elementy war¬ stwy kopiowej hartuje sie chemicznie i termicz¬ nie, a odsloniete miejsca blachy trawi sie za pomoca specjalnych roztworów, których glów¬ nym skladnikiem jest kwas azotowy. Jedinafk roztwory kwasu azotowego trawia metal nie tylko w odslonietych miejscach* na stronie uzytkowej for¬ my drukowej, ale równiez i odwrotna strone bla¬ chy chemigraficznej. Zabezpiecza sie ja wiec za pomoca trwalej^ kwasoodpornej warstwy lakieru o dobrej przyczepnosci do podloza. Warstwa lakie¬ ru musi byc bardzo gladka, poniewaz w przypadku grawerowania blachy metodami elektronicznymi jej powierzchnia powinna dobrze przylegac do stolu prózniowego urzadzenia do elektronicznego grawe¬ rowania. ** Z tych tez wzgledów bardzo wazne jest odpo¬ wiednie przygotowanie nieuzytkowej powierzchni :o 2 blachy chemigraficznej, albowiem jednoczesnie mu¬ si byc bardzo gladka i wykazywac dobra przyczep¬ nosc do lakieru.In the printing industry to receive printing forms are used as the substrate less chemigraphic metal sheets, preferably zinc. On the sanded surfaces of these sheets a photosensitive layer is applied which illuminates through the negative. The elements are lighted up through the light embroidered and loses its dissolution active in water, while elements non-water the light is removed, revealing the underneath at these points metal beds. Other elements of the sheet the copy joint is chemically and thermally hardened no, and the exposed places of the sheet metal are etched behind with the help of special solutions, the head of which one ingredient is nitric acid. Jedinafk nitric acid solutions digest metal not only at exposed places * on the user page of the format we print, but also the reverse side of the faint chemigraphy. So it is secured for by means of a durable acid-resistant varnish layer with good adhesion to the substrate. Lacquer layer ru must be very smooth, because in the case of metal sheet engraving by electronic methods the surface should adhere well to the table vacuum device for electronic engraving rowania. ** For these reasons, it is very important to respond proper preparation of unused space :about 2 chemigraphic sheet metal, because at the same time to be very smooth and show good grip paintability.
Wedlug znanych sposobów na przyklad wedlug Z. Kowalski: Powloki z tworzyw sztucznych. WNT; Warszawa 1967 powierzchnie blaclly szlifuje sie mechanicznie przez szczotkowanie, opalanie lub piskowanie i nastepnie przemywa alkoholem.By known ways, for example, by Z. Kowalski: Plastic coatings. WNT; Warsaw 1967, the blaclly surfaces are being ground mechanically by brushing, sunbathing or squeaking and then washed with alcohol.
Znane jest równiez czyszczenie blach przed la¬ kierowaniem za pomoca papieru sciernego o gra¬ nulacji 100—200 i nastepne odtluszczanie alkoholo¬ wym rozitwoireim weglanu wapnia. Przy takiej obróbce powierzchni powloka lakiernicza ma wprawdzie dobra przyczepnosc, ale stosunkowo chropowata powierzchnia obniza wyglad estetycz¬ ny blach. Ponadto na ostrych krawedziach rys szli¬ fierskich warstwa lakieru w czasie chemdgraficz- nego trawienia ulega czesto uszkodzeniu, co albo dyskwalifikuje, albo ogranicza zastosowanie blach na formy drukowe.It is also known to clean sheet metal before laundries abrasive paper steering against the grain nulation 100-200 and subsequent alcohol degreasing elution of calcium carbonate. With such surface treatment paint coat has Admittedly good adhesion, but relatively the rough surface lowers the aesthetic appearance sheets. In addition, scratches ran along sharp edges paint layer during chemdgraphic digestion is often damaged, which either disqualifies or limits the use of metal sheets for printing forms.
Chropowata powierzchnia uniemozliwia równiez zastosowanie blach lakierowanych do elektronicz¬ nego grawerowania, gdyz ich powierzchnie nie przylegaja szczelnie do stolu prózniowego urzadze¬ nia do grawerowania. Oprócz tego odbywajaca sie na sucho obróbka mechaniczna strony nieuzytko¬ wej blach powoduje stosunkowo duze zapylenie pomieszczen bardzo szkodliwymi dla zdrowia pro¬ szkami sciernymi i pylem metalicznym.The rough surface also prevents use of varnished sheets for electronic engraving as their surfaces do not adhere tightly to the vacuum table of the device for engraving. In addition, taking place dry machining of the unused side sheet metal causes relatively high dustiness rooms that are very harmful to health pro¬ abrasive glasses and metallic dust.
Znany jest równiez sposób odtluszczania plyt na 105 590105 590 przyklad cynkowych przez zmywanie ich powierz¬ chni roztworami alkalicznymi zawierajacymi wo¬ dorotlenek sodowy i weglan sodowy. Przy tym sposobie obróbki czesto na powierzchni blach po¬ zostaja biale plamy,, które obnizaja lokalnie przy¬ czepnosc warstwy lakieru do podloza powstaja w tych miejscach odpryski, co nie tylko obniza wy¬ glad estetyczny blach, ale takze wyklucza ich za¬ stosowanie na formy drukowe.The method of degreasing discs is also known 105 590 105 590 example of zinc by washing their surfaces They are alkaline solutions containing water sodium hydroxide and sodium carbonate. While the method of treatment often on the surface of metal sheets there are white spots, which reduce local addiction adhesion of the varnish layer to the substrate is formed by spattering in these places, which not only reduces the performance glad aesthetic sheet metal, but also excludes their za¬ use on printing forms.
Okazalo sie, ze mozna przygotowac, z wyelimi¬ nowaniem obróbki mechanicznej, powierzchnie blach chemigraficznych, które jednoczesnie sa glad¬ kie i wykazuja dobra przyczepnosc do lakieru.It turned out that you can prepare with elimination machining, surfaces chemigraphic sheets that are smooth at the same time and show good adhesion to paint.
Sposób obróbki powierzchni strony nieuzytkowej blach chemigraficznych wedlug wynalazku polega na poddaniu blachy chemigraficznej dzialaniu ka¬ pieli preparujacej zawierajacej w 1000 ml wody —50 g weglanu metalu alkalicznego, 2—10 g wo¬ dorotlenku metalu alkalicznego, 2,5—20 g fosfora¬ nu metalu alkalicznego, 10—30 g krzemianu me¬ talu alkalicznego oraz 0,5—20 g srodka powierzch¬ niowo^czynnego w temperaturze 60'—70°C przez oikres 3—10 mim. * Jako srodek powierzchniowo-czynny stosuje sie wedlug wynalazku produkty addycji tlenku etylenu do nienasyconego alkoholu tluszczowego ewentual¬ nie do mieszaniny nienasyconych alkoholi tlusz¬ czowych. Srodki te znane sa pod nazwa rokanol, na przyklad rokanol L-4, LN-75, 0-18, O-20, O-30, IT-5, 10C-15, OC-21 i inne.The method of surface treatment of the non-use side According to the invention, the chemigraphic sheets consist on subjecting the chemigraphic sheet to the action of canal preparation wash with 1000 ml of water - 50 g of alkali metal carbonate, 2 - 10 g of water alkali metal hydroxide, 2.5-20 g of phosphorus alkali metal, 10-30 g of metal silicate alkaline thallium and 0.5-20 g of surface agent at 60 ° -70 ° C for oikres 3-10 mim. * As a surfactant, it is used according to the invention, ethylene oxide addition products for unsaturated fatty alcohol, optional not to a mixture of unsaturated fatty alcohols ties. These agents are known as rocanol, for example Rokanol L-4, LN-75, 0-18, O-20, O-30, IT-5, 10C-15, OC-21 and others.
Zastosowanie sposobu obróbki blach chemigra¬ ficznych wedlug wynalazku nie tylko zapobiega powstawaniu plam na blachach, ale takze elimi- nuje obróbke mechaniczna, dzieki czemu wydat¬ nie skraca czas tego procesu. Powierzchnie blach , przygotowanych sposobem wedlug wynalazku sa czyste i gladkie oraz wykazuja dobra przyczep¬ nosc lakieru ochronnego.The use of the chemigraine sheet metal processing method according to the invention not only prevents the formation of stains on trays, but also to eliminate is mechanically processed, thanks to which the expense does not shorten the time of this process. The surfaces of the sheets prepared according to the invention are clean and smooth and show good grip resistance of the protective varnish.
