L\u2019objectif de chaque installation de pr\u00e9traitement est d\u2019am\u00e9liorer la mouillabilit\u00e9<\/strong> du substrat trait\u00e9. Pour ce faire, en ce qui concerne les mati\u00e8res plastiques, les cha\u00eenes mol\u00e9culaires apolaires doivent \u00eatre bris\u00e9es pour que les radicaux libres puissent se fixer. Il s\u2019ensuit la formation de mol\u00e9cules polaires auxquelles les mol\u00e9cules de la substance \u00e0 appliquer (peinture, vernis, adh\u00e9sif, etc.) peuvent se lier.<\/p>\n\r\n <\/div>\r\n <\/div> \r\n <\/div> \r\n \r\n <\/div> \r\n <\/section>\n\n\n

L\u2019ensemble des quatre proc\u00e9d\u00e9s physiques de pr\u00e9traitement de surface<\/strong> ont en commun de fonctionner avec un plasma, c\u2019est-\u00e0-dire un gaz ionis\u00e9. Le plasma est g\u00e9n\u00e9r\u00e9 par une d\u00e9charge \u00e0 haute tension dans les installations corona<\/a> et plasma<\/a>, et \u00e0 l\u2019int\u00e9rieur de la flamme chaude lors du flammage<\/a>.<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n

Contrairement aux proc\u00e9d\u00e9s chimiques humides, l\u2019activation de surface physique n\u2019engendre pas de d\u00e9chets dangereux<\/strong> n\u00e9cessitant une \u00e9limination co\u00fbteuse. De plus, les phases de s\u00e9chage, indispensables lors de l\u2019activation chimique, sont supprim\u00e9es. En r\u00e8gle g\u00e9n\u00e9rale, dans la production, le pr\u00e9traitement physique est int\u00e9gr\u00e9 directement en amont du rev\u00eatement.<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div>\r\n

L\u2019utilisation d\u2019une installation de pr\u00e9traitement est toujours profitable lorsque des surfaces hydrophobes<\/strong> doivent \u00eatre mouill\u00e9es avec un liquide tel qu\u2019une peinture, un vernis ou un adh\u00e9sif. De telles surfaces se retrouvent dans de nombreuses mati\u00e8res plastiques courantes, mais les m\u00e9taux, les c\u00e9ramiques, le verre et de nombreuses sortes de papier pr\u00e9sentent \u00e9galement de faibles tensions de surface. Ce n\u2019est que gr\u00e2ce au pr\u00e9traitement que les adh\u00e9sifs et les couches de finition peuvent se lier durablement \u00e0 de tels substrats.<\/p>\n<\/div>\r\n \r\n <\/div>\r\n \r\n <\/div>\r\n \r\n <\/div> \r\n <\/div>\r\n <\/div> \r\n <\/div> \r\n <\/div> \r\n \r\n <\/section>\r\n
