A.1 Negative pressure ammonia filling method
Appendix A
(Informative Appendix)
Ammonia filling method for calcium carbide packaging
Use three valves to connect the packaging, vacuum pump and nitrogen filling pipe. First, close the nitrogen filling pipe, open the vacuum pump to extract the gas in the packaging, then close the vacuum pump, open the nitrogen filling pipe to fill nitrogen until positive pressure is generated in the packaging. A.2
Positive pressure nitrogen filling method
When filling calcium carbide, insert a nitrogen filling tube into the bottom of the package, start filling with nitrogen, remove the mixed gas in the package from the bottom, then close the opening, and then fill with nitrogen from the nitrogen filling hole on the top cover. 6
