Asia Exclusive - high boron glass frosting powder special

TBS-305 special high boron glass frosting powder TBS-305 rapid-type high boron Frosting quartz glass powder is widely used in various types of quartz glass, lighting, deep processing of quartz glass tube containing boron products. Finished features: surface, even delicate, hand lubricant, hazy look beautiful, translucent and soft. [Glass products Frosting] will be placed in a clean glass products Frosting 15-20 minutes (high boron content of products Frosting time is extended), 30 seconds after removing the drip-dry, rinse with water. [Packing] 25Kg / Bag with acid ratio (by weight): Frosting powder: hydrofluoric acid = 1: 0.5 (the main points in the frosting powder materials and small material, a ratio of 4: 1 as with 2kg powder Frosting Ingredients 0.4kg to 1.6kg small material is hydrofluoric acid 1kg) For example: the 25 kg Frosting powder into a plastic bucket, while stirring, 12.5 kg of hydrofluoric acid (HF concentration ≥55%, do not avoid adding low excessive concentration of hydrofluoric acid or hydrofluoric acid), the Frosting powder into a plastic container of hydrofluoric acid was added slowly, stirring until evenly covered, curing more than 24 hours (the longer the better aging time), should be stirred during several times to fully reflect the new configured Frosting relatively thick, the temperature drop will be cooling phenomenon, after ripening liquid viscosity temperature can resume normal use. [Frosting Operation] 1, cleaning: good before frosting with plastic gloves will be watered hydrofluoric acid (HF 1 ratio of water to 6) diluted in clean glassware, glassware cleaning with a soft cloth for 30-60 seconds (ensure piece of glassware are cleaned - so as not to affect Frosting effect) after acid washing, rinse the glass with tap water (tap water, place drops of clean water for 20-30 seconds, so the excess water into the Frosting impact Frosting liquid efficacy). 2, mixing, filtration: Before Frosting Frosting liquid that has been configured with a plastic (or bamboo stick) stir until evenly, then prepare 80 mesh screen will maturation Frosting good medicine all filters once and the filtrate Rewind kits (sand with shower), residue (crystal) with plastic barrels good (After Frosting glass work is complete, the screen 80 of the crystal installed back Frosted solution to fully dissolve, so repeated operation, so residue (crystals) can be recycled, extend the life of Frosting). 3, Frosting: Place the glass products soak into Frosting of glass products for the first time immersion Frosting: A clean glass products completely immersed in the liquid inside 10 minutes after removing the glass with tap water clean products ( again after the clean glassware completely immersed in the liquid inside 10 minutes: Do not rinse the glass into the excess moisture from entering the liquid inside to prevent dilution of the liquid reduced efficacy) of glass products for the second soaking Remove the glassware with tap water cleaned using water dry or drying can be. (When Frosting just started, Mongolian eclipse strong force, after a period of eclipse Mongolia, Frosting time is extended) [add add] For purposes Frosting long-term use, use the following method to add: 1, No excess cleaning fluid and water into the old Frosting, configuration powder Frosting: hydrofluoric acid (1: 0.5) was concentrated Frosting, after aging old added to a liquid, 2, into excess cleaning Old Frosting liquid and water, and destroyed part of the supernatant was added maturation has previously concentrated Frosting. [Note] Frosting aging time and ambient temperature curing longer the best results. In Frosting process should wear protective glasses and rubber gloves as Frosting accidentally splashed into the eyes, immediately wash with water.
