Glass ink manufacturers in the production of water-based glass ink and the use of the process, due to the cleaning of the equipment, will produce a certain amount of waste water. How to deal with water-based glass ink wastewater?
chemical oxidation-coagulation process
The composition of wastewater mainly includes water-based glass ink, starch and surfactant. Through the use of oxidation decolorant KMnO4, H2O2, NaClO, activated carbon selectivity test; Through the flocculant: Y-13, FSH7, FCH3, FO4248, AN910SH screening test and dosage and pH adjustment test. The results showed that under the best experimental conditions of adding the best oxidant NaClO15g g/L, the best coagulant FCH 30.2g/L and pH adjustment of 8.5, the CODcr removal rate reached 94% and the chroma removal rate reached 100.

Glass ink is an ink that can adhere to glass
Glass ink (glass printing ink) can be printed on glass and can be firmly attached to the ink.
1, glass ink can be used to manufacture craft glass or painted glass and other crafts, because the glass paint color ability, waterproof function is good, not easy to change color and other functions, so in the manufacture of these crafts will not occur when cracking blistering phenomenon, can be very good protection of glass, but also increased the ornamental glass, in the living room dining room to play a decorative role.

On the use of glass ink steps and key points
1. After opening the barrel, investigate the condition of glass ink in the barrel. If there is no normal line, mix the paint solution in the barrel evenly.
2, according to the proportion shown in the label paint, first the curing agent and main paint mixed merger mixing war, and then participate in the diluent, adjust to the construction viscosity can be construction.
3, the substrate cleaning: with talcum powder or public cleaning agent scrub the glass appearance, thoroughly eliminate the glass appearance stains, adhere to the glass appearance clean and monotonous.
4. Spraying: The distance between large spray guns and small spray guns should be 20-30cm and 15-25cm respectively. Spraying air pressure should be 0.3-0.6 (about 3-6kg/C㎡) to adjust the spray gun to a suitable oil and air output to ensure uniform atomization.
5. In case of high humidity in the construction environment, the modifier can be scrubbed on the glass substrate or the sprayed paint film can be baked at low temperature to ensure the quality of the product.
6. It is necessary to use up the glass ink within the useful use time, within 3 hours in summer, and within 8 hours in winter.
