Sobre IBD

Foi desenvolvida uma composição de vidro borossilicato dopado com fluoreto de sódio e silício, mais refinada e livre de sementes, bolhas e cordões. A adição do composto de fluoreto acelerou a fusão do vidro, mas reduziu a viscosidade e a tensão superficial. Foram feitas muitas variações na composição do vidro borossilicato padrão (7740) para desenvolver uma nova composição que fosse fundida de acordo com as condições economicamente disponíveis. O forno elétrico com sistema de agitação era muito caro, o que não era viável para o Paquistão desenvolver um vidro tão caro. Assim, um forno a gás sem sistema de agitação a uma temperatura comparativamente mais baixa foi usado para a fusão desses vidros, em vez do forno elétrico. Este vidro foi desenvolvido pela primeira vez no Paquistão em escala laboratorial, com os recursos e instalações disponíveis no nosso país.

    Opracowano skład szkła borokrzemowego domieszkowanego fluorkiem krzemu sodu, który był bardziej wyrafinowany, wolny od ziaren, pęcherzyków i splotów. Dodatek związku fluorku przyspieszył topienie szkła, ale zmniejszył jego lepkość i napięcie powierzchniowe. Wprowadzono wiele zmian w standardowym składzie szkła borokrzemowego (7740) w celu opracowania nowego składu, który można ...
