Abstract

Perfectionnement au traitement thermique de verre Le verre, chaud, est mis en contact avec un mélange fluidisé au gaz de matières en particules dont l'une au moins est apte à engendrer du gaz lorsqu'elle est chauffée par le verre chaud. Les matières sont mélangées en des proportions choisies pour conférer au mélange une capacité calorifique et un indice de fluidité de nature à assurer le traitement thermique requis. Le procédé convient pour la trempe thermique de feuilles de verre pour pare-brise de véhicule.
