Contribution for study on curing of organic coatings in papers, by electron beam

Creators

Description

The behaviour of national raw material is studied: paper, resins vamishes used on the surface finishing furniture, when subnitted to electron beam curing in an inert atmosphere. The dosimetric control of the irradiation system was made by using CTA films. The minimum cure dose obtained for the EBC 1650/3009 varnish(national polyester) was 2.4 Mrad and of 2.0 Mrad for the EBC 1650/3010 (imported polyester from Germany). The optimun cure dose for both was 3.0 Mrad. The papers impregnated with EBC varnish of with conventional varnish were measured mechanically for resistance in traction and an evaluation of resistance of the finished surfaces with the ebc varnishes was made. The coatings obtained with the EBC varnishes manufactured nationally were compared with the conventional vamishes of thermal cure and with paper samples impregnated and cured in Germany. (author)

Abstract (Portuguese)

Estuda-se o comportamento de materias-primas nacionais: papeis, resinas e vernizes, usados no acabamento superficial de moveis, quando submetidos a cura induzida por feixes de eletrons em atmosfera inerte. O controle dosimetrico do sistema de irradiacao foi feito por meio de peliculas de CTA. A dose minima de cura obtida para a verniz EBC 1650/3010 (poliester importado da Alemanha). A dose otima de cura para ambos foi de 3,0 Mrad. Nos papeis impregnados com verniz EBC ou com verniz convencional foi medida a resistencia mecanica a tracao, bem como foi feita uma avaliacao da resistencia quimica das superficies acabadas com os vernizes EBC. Os revestimentos obtidos com os vernizes EBC da fabricacao nacional foram comprados com os vernizes convencionais de cura termica e com a mostra de papel impregnado e curado na Alemanha. (autor)
