16

Return halogen

The chloride ion content of less than 5%, and definitely do not get damp, not get halogen

The chloride ion content of less than 10%, will get damp, and sometimes back to halogen phenomenon

The chloride ion content of less than 20% will get damp back to halogen and chalking

The chloride ion content of less than 35%, it will certainly damp back to halogen and powder
