Method for making noodles using dodam rice and konjac and noodles manufactured using the same

摘要

The present invention is a cylinder pre-treatment step of removing moisture in the cylinder; And a fluorinated passivation film forming step of forming a fluorinated passivation film on the inner surface of the cylinder using anhydrous hydrofluoric acid. It relates to a surface treatment method inside a high-purity hydrogen fluoride storage container, including hydrogen, oxygen, etc., even during long-term storage of high purity hydrogen fluoride. It is possible to provide a surface treatment method capable of minimizing the amount of impurity gas generated, and a storage container of high-purity hydrogen fluoride surface-treated accordingly.
