Polymer permeation tube for preparing standard gases using permeation method and fabrication method thereof

摘要

PURPOSE: A polymer penetration pipe and a manufacturing method thereof are provided to manufacture reactivity, corrosiveness, toxicity material, or moisture reference gas. CONSTITUTION: A polymer penetration pipe includes a raw material for manufacturing reference materials. The inner surface of the penetration pipe includes polymer materials which are reformed to the fluorine. The polymer material includes one among silicon, poly tetra fluro ethylene, polyethylene, polypropylene, polyvinylacetate, polyamide, polyester, polyethylene terephthalate, nylon and their combination.
