Abstract
(DE)
Verwendung eines wasserlöslichen Glases zum Korrosionsschutz von Glaswaren, wobei das wasserlösliche Glas hergestellt ist aus wenigstens einer Verbindung, die in Reinigungs- und/oder Spülvorgängen einer Geschirrspülmaschine ein für den Korrosionsschutz von Glaswaren aktives Agens freisetzt, wobei jede dieser Verbindungen jeweils höchstens 85 Mol-% des Glases ausmacht und die Löslichkeit des wasserlöslichen Glases durch einen Masseverlust von wenigstens 0,5 mg unter den in DIN ISO 719 angegebenen Bedingungen definiert ist.
(EN)
The invention relates to the use of a water-soluble glass as corrosion protection for glassware. According to the invention the water-soluble glass consists of at least one compound which in cleaning and/or rinsing cycles of a dishwashing machine releases an agent which protects glassware against corrosion. Each of these compounds accounts for no more than 85 molar % of the glass and the solubility of the water-soluble glass is defined by a mass loss of at least 0.5 mg under the conditions specified in DIN ISO 719.
(FR)
L'invention concerne l'utilisation d'un verre hydrosoluble pour protéger de la verrerie contre la corrosion. Ce verre hydrosoluble est produit à partir d'au moins un composé qui libère, pendant le processus de lavage et/ou de rinçage d'un lave-vaisselle, un agent actif pour la protection contre la corrosion de la verrerie, chaque composé étant constitué d'au maximum 85 % en moles de verre, et la solubilité du verre hydrosoluble étant définie par une perte massique d'au moins 0,5 mg, dans les conditions spécifiées dans DIN ISO 719.
