Abstract

PURPOSE: To collect fluorides in a stable form of calcium flouride being safe and harmless for the human body and easy to combine, by dispersing calcium lactate and sticking on the gas permeable porous base material by using as the scavenger of fluorides.
CONSTITUTION: Aqueous solution or suspension of calcium lactate, is impregnated into the gas permeable porous base material such as natural or synthetic fiber paper, nonwoven fabric and treated base material is dried and then, calcium lactate is uniformly dispersed and stuck. Said treated material is used for the scavenger of gas containing hydrogen fluoride and fluorides generated at welding excution time. Stable calcium fluoride is formed by contacting with treating gas. Thus, hydrogen fluoride and fluorides are easily collected in a safe form for the human body.
