Cada metal possui uma recomenda\u00e7\u00e3o de tratamento e a falta ou excesso de oxida\u00e7\u00e3o pode contribuir no aparecimento de trincas.<\/h4>\n

No caso de falta de oxida\u00e7\u00e3o, isso pode causar trincas e lascamentos de bordo, devido a insufici\u00eancia de ader\u00eancia. J\u00e1 o excesso ir\u00e1 ocasionar fraturas de \u00f3xido, quando o opaco n\u00e3o adere ao metal. Sendo assim, para promover o m\u00e1ximo de uni\u00e3o, siga rigorosamente a recomenda\u00e7\u00e3o do fabricante.<\/h4>\n

    Para que se obtenha uma boa ader\u00eancia ao metal \u00e9 de suma import\u00e2ncia que haja uma primeira queima de opaco (wash) em temperatura mais elevada (10~20 \u00baC acima do convencional).

    Cuidados com a solda<\/strong><\/h3>\n

    Se houver solda na estrutura, verifique a temperatura ideal, segundo a indica\u00e7\u00e3o do fabricante. Em pe\u00e7as com Solda Fit, recomenda-se baixar de 10~20 \u00baC a temperatura final de oxida\u00e7\u00e3o para evitar distor\u00e7\u00e3o da estrutura ap\u00f3s a queima. Para trabalhos pequenos (de at\u00e9 3 elementos) n\u00e3o ultrapasse 970 \u00baC. J\u00e1 em casos de pontes fixas extensas (acima de 7 elementos), baixe a temperatura para 960 \u00baC. Se necess\u00e1rio, a diferen\u00e7a da temperatura de oxida\u00e7\u00e3o pode ser compensada, aumentando o tempo de perman\u00eancia em 1 a 2 min. no processo.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″ shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_link_target=”_self” column_shadow=”none” column_border_radius=”none” width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none” column_link=”http:\/\/talmax.com.br\/talmax-digital\/componentes-proteticos\/”]
