Abstract
Prostriedok vytvořený roztokom chloridu sodného a vody používaný na odstraňovanie silikonových olejov z povrchu termoplastických umělých hmót před nanášaním farby. Použitie tohoto roztoku zabezpečí dostatočné spojenie nanášanej farby s podkladom, po zaschnutí sa farba nedá zotriet a nelúpa sa.A product made from a solution of sodium chloride and water used to remove silicone oils from the surface of thermoplastic plastics before applying paint. The use of this solution ensures sufficient adhesion of the applied paint to the substrate, and after drying the paint cannot be wiped off and does not peel.
Description
Vynález sa týká použitia roztoku chloridu sodného na odstraňovanie silikonových olejov z termoplastových výliskov před nanášanim farby sieťotlačou.The invention relates to the use of a sodium chloride solution for removing silicone oils from thermoplastic moldings before the ink is applied by screen printing.
Doposial sa na odmastovanie výliskov z termoplastov používajú různé druhy odmasťovadiel - saponáty, rozpúšťadlá alebo riedidlá, ktoré nezabezpečujú důkladné odstránenie silikonových olejov, ktoré zostávajú na povrchu výliskov po vybratí zo vstrekovacích foriem. Farba nanesená sieťotlačou na takto nedokonale odmaštěný povrch výliskov nie je dostatočne súdržná s podkladom a skoro sa začne odlupovat.Until now, various types of degreasers - detergents, solvents or thinners have been used to degrease thermoplastics moldings, which do not ensure the thorough removal of the silicone oils that remain on the moldings surface after removal from the injection molds. The ink applied by screen printing on such an imperfectly degreased surface of the moldings is not sufficiently cohesive to the substrate and will soon begin to peel off.
Vyššie uvedené nedostatky sú odstránené použitím roztoku na odstraňovanie silikonových olejov z povrchu termoplastov před nanášanim farby sieťotlačou podlá vynálezu, ktorého podstata spočívá v tom, že roztok je vytvořený rozpuštěním 0,2 až 0,5 kg chloridu sodného v 1 litri vody.The above drawbacks are overcome by the use of a silicone oil removal solution from the surface of the thermoplastics prior to the application of silk screen printing according to the invention, the solution being formed by dissolving 0.2-0.5 kg of sodium chloride in 1 liter of water.
Výhodou použitia roztoku chloridu sodného vo vodě, na odstraňovanie silikonových olejov používaných ako separačná vložka vo vstrekovacích formách je, že farba nanesená na takto odmaštěné výlisky z termoplastických hmůt je dostatočne kompaktná s podkladom, nedá sa po zaschnuti zotrieť a nelúpa sa.The advantage of using a sodium chloride solution in water to remove the silicone oils used as a release liner in injection molds is that the paint applied to such degreased thermoplastic moldings is sufficiently compact with the substrate, cannot be wiped off and does not peel after drying.
Pri použití roztoku chloridu sodného podlá vynálezu sa postupuje tak, že výlisky z termoplastov sa vyperú v roztoku, ktorý je vytvořený v koncentrácii na 1 liter vody 0,2 až 0,5 kg kuchyňskéj soli (NaCl) a potom sa prevedie oplach v čistéj vodě. Pri nanášaní farby sa postupuje už bežne používaným spůsobom.Using the sodium chloride solution according to the invention, the thermoplastics moldings are washed in a solution which is formed in a concentration of 1 liter of water 0.2 to 0.5 kg of common salt (NaCl) and then rinsed in clean water. . The application of the paint is carried out by a commonly used method.
