Glass products are more and more common in our life, we can find them in the kitchen, living room and even in the bedroom, we often use glass bottles to hold spirits, wine and drinks.
In order to decorate the bottle technicians provide many options, spray paint and frost. Do you know how to produce the frosting bottle？
The technician offers three options for froste.
The first is acid corrosion, technical personnel debugging a weak acid liquid, generally use oxalic acid in order to ensure the safety of operators; The acidic liquid is concentrated in a metal container, and the belt dips the bottle into the liquid for about 1-2 minutes before it is evenly coated with frost, which is actually corroded by the acidic liquid.
The second is to sand the bottle, which is safe enough and environmentally friendly, because no dangerous liquid is involved, and the machine keeps churning the stuff around the bottle, and after a few minutes the bottle is polished.
The third option is spray paint, technicians mix a special paint, this option produces more, but the cost is better.
