Abstract
Išradimas priskiriamas apsauginių dujų, susidedančių iš 0.0010-0.100 tūrio masės % azoto manoksido. 0-90 tūrio masės % helio, 0-5 tūrio masės % vandenilio, 0-50 tūrio masės % anglies dioksido ir likęs kiekis argono, gamybos būdui. Išradimas objektas taip pat yra dujų mišinys iš kurio gaminamos minėtos apsauginės dujos.@Apsauginių dujų gamybos būdas charekterizuojamas yuo, kad anglies monoksidas ištirpinamas kondensuotam argone iki 0.0010-0.100 tūrio masės % koncentracijos, skaičiuojant dujinei fazei, po to garinant gautą tirpalą įmaišomis likusios sudedamosios dalys tokiomis proporcijomis, kad gautų numatytos sudieties apsaugines dujas.@Dujų mišinys, apsauginių dujų gamybai, charakterizuojamas yuo, kad susideda iš 0.0010-0.10 tūrio masės % azoto monoksido ir kondensuoto argono, skaičiuojant dujinei fazei, ir yra geriau, kai laikoma dideleme slėgyje.The invention relates to a protective gas consisting of 0.0010-0.100% by weight of nitrous oxide. 0-90% by weight helium, 0-5% by weight hydrogen, 0-50% by weight carbon dioxide and the remaining amount by argon. The object of the invention is also a gas mixture from which said protective gas is produced. The method of producing the protective gas is charcoalized by dissolving the carbon monoxide in a condensed argon to a concentration of 0.0010 to 0.100% by weight, based on the gaseous phase, followed by evaporation of the resulting solution by stirring the remaining ingredients. @ Gas mixture for the production of protective gases is characterized by the presence of 0.0010-0.10% by weight of nitrogen monoxide and condensed argon, calculated for the gaseous phase, and is better when kept under high pressure.
