Os selantes de silicone se tornaram um material quase indispens\u00e1vel nos setores modernos. Sua not\u00e1vel flexibilidade, v\u00e1rias formas de resist\u00eancia a intemp\u00e9ries e durabilidade de longo prazo s\u00e3o os principais fatores que contribuem para esse status. Arranha-c\u00e9us, reparos dom\u00e9sticos, se assim posso dizer, e quase todo tipo de necessidade de veda\u00e7\u00e3o estrutural ou geral se beneficiam dessas caracter\u00edsticas de desempenho superior. Este artigo abordar\u00e1 as aplica\u00e7\u00f5es industriais mais espec\u00edficas.<\/p>\n
Os arranha-c\u00e9us modernos dependem do silicone para o envidra\u00e7amento de fachadas e paredes cortina. A uni\u00e3o estrutural excelente e a impermeabilidade quase perfeita s\u00e3o fornecidas; as juntas herm\u00e9ticas\/estanques devem suportar o movimento constante do vento e todas as formas de deslocamento do edif\u00edcio.<\/p>\n
Os selantes aplicados a janelas e portas t\u00eam a finalidade b\u00e1sica, mas importante, de bloquear a infiltra\u00e7\u00e3o de ar e alguma forma de entrada de \u00e1gua. O silicone de cura neutra \u00e9 particularmente eficaz nesse caso, sendo a efici\u00eancia energ\u00e9tica e, at\u00e9 certo ponto, o isolamento ac\u00fastico os resultados finais.<\/p>\n
Em ambientes propensos \u00e0 umidade, h\u00e1 o uso de silicones sanit\u00e1rios. A preven\u00e7\u00e3o de mofo e bolor \u00e9 a principal preocupa\u00e7\u00e3o, e aditivos do tipo fungicida s\u00e3o frequentemente inclu\u00eddos; o aumento da \u2018vida \u00fatil\u2019 da \u00e1rea vedada \u00e9 um benef\u00edcio secund\u00e1rio, mas relacionado.<\/p>\n
Os fabricantes de autom\u00f3veis os utilizam - as juntas do motor s\u00e3o o principal exemplo, a colagem do para-brisa, toda e qualquer redu\u00e7\u00e3o de ru\u00eddo de vibra\u00e7\u00e3o (NVH). A resist\u00eancia ao calor (mais de 250\u00b0C, se bem me lembro) e a elasticidade simples os tornam quase ideais para montagens de ve\u00edculos.<\/p>\n
Confi\u00e1vel na avia\u00e7\u00e3o, isolando tanques de combust\u00edvel, pequenas cabines e\/ou janelas. A baixa libera\u00e7\u00e3o de gases e a resist\u00eancia quase universal a todos os extremos de temperatura e press\u00e3o s\u00e3o os principais fatores.<\/p>\n
Os conjuntos eletr\u00f4nicos sens\u00edveis precisam de alguma forma de prote\u00e7\u00e3o contra elementos internos e externos: umidade, poeira e\/ou exposi\u00e7\u00e3o a produtos qu\u00edmicos. O silicone fornece todos os itens acima e, ap\u00f3s a cura, ainda mant\u00e9m a flexibilidade.<\/p>\n
Os pain\u00e9is solares, pelo menos, exigem selantes resistentes a UV\/intemp\u00e9ries. Colagem de vidro e\/ou encapsulamento de m\u00f3dulos fotovoltaicos, tudo a ponto de ser uma \u2018\u00faltima linha de defesa\u2019.<\/p>\n
Pesados ou n\u00e3o, todos os tipos de veda\u00e7\u00f5es e gaxetas em m\u00e1quinas e\/ou equipamentos mar\u00edtimos sempre far\u00e3o parte do mundo industrial.<\/p>\n
Os propriet\u00e1rios de im\u00f3veis gostam de ver o resultado final de todos os itens acima como uma esp\u00e9cie de veda\u00e7\u00e3o \u2018permanente\u2019, e todos sabemos que o silicone faz e sempre far\u00e1 parte de nossas vidas.<\/p>\n
Os selantes de silicone, em todos os sentidos industriais ou dom\u00e9sticos, s\u00e3o uma parte verdadeira e duradoura da vida moderna.<\/p>","protected":false},"excerpt":{"rendered":"
