FAQ
Q1: Shin ruwa na cryogenic argon ya fi sanyi fiye da ruwa nitrogen?
Amsa: A'a. Liquid nitrogen yana da wurin tafasa na -196°C (-320°F), yana sa ya yi sanyi kusan digiri 10 ma'aunin celcius fiye da argon ruwa na cryogenic, wanda ke tafasa a -186°C (-303°F). Idan aikace-aikacenku ya dogara kawai akan isa mafi ƙarancin zafin jiki don daskarewa, nitrogen ya fi girma.
Q2: Me yasa argon ruwa na masana'antu ke amfani da tsada don aiwatarwa fiye da nitrogen?
Amsa: Bambance-bambancen farashi ya zo zuwa ga yalwar yanayi da wahalar cirewa. Iskar da muke shaka tana da kusan kashi 78% na nitrogen, wanda ke sa ya zama mai sauƙi da arha don fitar da shi ta Rukunin Rarraba Jirgin Sama (ASUs).
