Ordinary Glass Frosting powder
Price Term: FOB
Package: 25kg/pcs
Common Glass Frosting Powder ST-101 can frost Sodium-Calcium-Silicon glass such as lamp glass, flat glass, bottles, arts glass... ST-101 is based on industrial grade Hydrochloric Acid. It is a new type environment-friendly powder that allows a better recycling . Stable and easy to use the powder makes your glass appears softer and white.
Frosting Operation >> Preparation of the Frosting Solution
·Mature the Frosting solution at least 24 hours before use．
·The ratio of powder ST-101 to Hydrochloric Acid
(≥31) is 1:0.50 ．
·Keep the powder in a plastic container, slowly pour Hydrochloric
Acid in, and keep stirring the solution evenly. Finally, cover
the container.
·Keep maturation over 24 hours before use (The longer, the better)
·The newly-prepared solution is too thick, and its temperature
will fall down slowly, so don"t apply it until it comes back to
be normal in temperature and thickness.
Frosting Operation >>Frosting Process
·Constantly stir the matured solution to be even completely ．
·Dip the clean glass wares into the solution for 20-40 seconds ．
· Take out the etched glass to drop for 10-20 seconds ．
·In the beginning, the solution is fairly thick. However the
etching time should be longer when the solution becomes less
thick after etching for some time ．
·The frosting time varies with the temperature and chemical
compositions．
·For dirty glass, use 15 Hydrochloric Acid to wash．
Frosting Operation >>Wash Process & Dry · Rinse and wash the frosted glass wares under the running water
· Dip the glass into the 5-10 diluted Hydrochloric Acid for 20-60
seconds to make brasive parparticles on the glass easy to
remove ．
·Rinse and wash the glass again under the running water
and dry it with air for package．
Etching Operation >>Treatment of Waste Water
· Neutralize waste water by lime stone to PH=7-9 ．
·Let off the waste water after filtrating the dreg out of it ．
Etching Operation >>Refills
To keep the etching solution available longer, the following approaches can be adopted: ·Add the 1:0.50 matured solution to the solution in which there
is no more pre-treatment solution mixed ．
· If more pre-treatment solution has been mixed with the solution,
You can add matured thick solution to it (The Ratio of the
powder to Hydrochloric Acid=1:0.30-1:0.40) ．
·Check out if the solution is still effective by comparing
its proportion. The regular solution is in the proportion of
1.36-1.37 at indoor temperature ．
Etching Operation >>Cautions
·The maturing time of the solution relates to the temperature.
The best time is ranged from 2 to 5 days.
·During etching, the workers should wear eyes-safety glasses and
rubber gloves ．
·If the eyes touched the liquid, please wash with the clean
water immediately.
·With a density of 1.14, 31 industrial grade Hydrochloric
Acid will make frosting available longer , leading to a
larger yield.
