Em vidros automotivos, a seguran\u00e7a nunca \u00e9 opcional \u2013 mas a durabilidade tamb\u00e9m n\u00e3o.

Um material que demonstra claro potencial para essa fun\u00e7\u00e3o exigente \u00e9 o vidro borossilicato. Neste post, analisamos por que ele \u00e9 um bom candidato e o que \u00e9 necess\u00e1rio para dobr\u00e1-lo com sucesso.<\/em><\/p>\n

Comparado ao vidro sodo-c\u00e1lcico tradicional, o vidro borossilicato oferece melhor resist\u00eancia a impactos e prote\u00e7\u00e3o contra arranh\u00f5es. Em testes, por exemplo, o SCHOTT BOROFLOAT\u00ae 33 \u00a0demonstrou resist\u00eancia at\u00e9 quatro vezes maior a rachaduras em condi\u00e7\u00f5es especiais de impactos bruscos \u2013 uma clara vit\u00f3ria para a durabilidade a longo prazo. Por isso, \u00e9 uma escolha inteligente para o painel externo de para-brisas laminados. O vidro sodo-c\u00e1lcico, mais econ\u00f4mico, pode permanecer na parte interna.<\/p>\n

No entanto, combinar dois tipos diferentes de vidro traz consigo seus pr\u00f3prios desafios de dobra.<\/p><\/blockquote>\n

Curvatura de vidro mais complexa<\/h3>\n

Propriedades do material, como viscosidade e expans\u00e3o t\u00e9rmica, variam significativamente entre o vidro borossilicato e o vidro sodo-c\u00e1lcico. Isso significa que os dois vidros amolecem e expandem em taxas diferentes durante o aquecimento, aumentando o risco de defeitos visuais, como pontos quentes, se o processo n\u00e3o for rigorosamente controlado.<\/p>\n

Para uma curvatura bem-sucedida, o forno precisa aplicar mais calor ao vidro borossilicato, sem superaquecer o vidro sodo-c\u00e1lcico. Esse equil\u00edbrio \u00e9 dif\u00edcil de ser alcan\u00e7ado com equipamentos padr\u00e3o, mas poss\u00edvel com um forno de curvatura de para-brisas flex\u00edvel e um ajuste adequado do processo.<\/p>\n

Sucesso com as ferramentas certas<\/h3>\n

Uma s\u00e9rie de ensaios confirmou que a combina\u00e7\u00e3o borossilicato-cal sodada pode ser curvada com boa qualidade \u00f3ptica \u2013 desde que o processo de aquecimento seja ajustado corretamente. Como o borossilicato requer temperaturas de curvatura mais altas, o controle cuidadoso da intensidade e da dire\u00e7\u00e3o do aquecimento \u00e9 fundamental..<\/p>\n

Conclus\u00e3o: ao repensar o processo de dobra, as montadoras podem acessar os benef\u00edcios do vidro de borossilicato para para-brisas mais dur\u00e1veis, sem comprometer a qualidade.<\/p><\/blockquote>\n
