Formulation and use of glass etching solution
In the curen bone, and the volatile gas is toxic and corrosive.
Pickling of glass must be particularly careful, therefore, need to have professional extraction, washing equipment, including eliminate corrosive gas shield, wide mouth plastic containers, suitable storage space and working equipment. The long handle of plastic is a useful tool, but it can also be used after wrapping wax in a metal spoon. Staff members should wear protective clothing, protective boots and mask when dealing with acid. It is recommended to be equipped with alkaline neutralization equipment to solve the emergency.
The depth and effect of corrosion depends on the strength and temperature of the acid, the quality of the glass and the soaking time. Pickling glass needs to adjust the pickling method according to different circumstances. Generally, four water nuclear 60% concentration of hydrofluoric acid is widely used, if must carry on the depth of pickling, requires 2 part water and 1 copy of hydrofluoric acid, must remember to add acid to water, instead of adding water to acid. 4 portions of water and 1 acid can corrode approximately 1. 5mm of glass in 2 hours. One recipe from Scandinavia: three 60% concentrations of hydrofluoric acid + 5 portions of water + 1 90% concentration of sulfuric ac
