Temperature of 85 ~
2 to 5 seconds. Custom Made Swooper Flags
In a closed process, the board more than most of the ink off, some of the residual available scrubbing brush in water for brushing, cleaning can be sent to the dry process, post-processing (metal processing technology).
6. Color signs printed on aluminum oxide. Printed Teardrop Flags Aluminum flat anodized signage signage varieties, is widely used. It has beautiful, bright, high hardness, good abrasion resistance. The previous process for aluminum cutting, mechanical polishing, chemical polishing, oxidation; indirect legal system version, lithopone Houqi and alkyd varnish to protect the ; dyed pulp coloring. This process, regardless of the plate or staining materials, complex processes, Custom Made Swooper Flags low anti-Indian forces, the resolution is poor, the high cost of shortcomings.
Existing conditions, it is possible to compile a set of processes is relatively simple, good quality, high efficiency and new technology. New technology to direct the legal system of non-toxic Custom Printed Teardrop Flags diazo photosensitive plastic plates, practice has proved to the plate fast, high resolution, high anti-Indian forces, with less material requirement. India and protect the paint, dyeing, retreat printed material processes merged into one, that is homemade water-based stain printed materials, direct staining, a series of chromatic, without color tank. Which greatly simplifies the whole process and operating procedures, so that the plane oxidation dyeing signs With the new method. Now the main process of this new method are described below: (1) system of plates. Using 250 mesh polyester plate sensitive adhesive Diazoresin sensitive adhesive, scraping gum six thick film. Custom Made Swooper Flags Proofing light 1000W Abstract lamps. The light from the
② electrolytic oxidation. Cutting aluminum oxidation by mechanical polishing and acid polishing. The process recipe and conditions below.
Three acid polishing:
Of H2SO4 15%;
Of HNO3 10%.
Temperature of 90 ~
Voltage 10 ~ 24V;
Current density of ~ 0.5
Time of 40 to 50 minutes.
Aluminum plate cold water, and then, and were then rinse, drying can be . Teardrop Flags Wholesale
③ silk screen stain. First the preparation of printed materials, printed materials for the water-soluble paste. Methyl cellulose and sodium alginate slurry, the dyes used in the anionic dyes (direct dyes, acid
Dyes and reactive dyes). The formula is as follows:
Hydroxymethyl cellulose 55%
Sodium alginate, 15%
0.6% sodium hexametaphosphate
Dye 30% Custom Made Swooper Flags
Preparation of the hydroxymethyl cellulose, sodium alginate, respectively, the first in the container stirring a small amount of cold water, and trace gradually added. After the increase, and then stirred for 10 minutes. At rest 24 hours after adding methyl cellulose, the margin of boiling water dissolve until the temperature dropped to 50 ~ 60 ° C by adding a margin sodium alginate. Personalized Advertising Flags Dye method of preparation is the same as the ordinary oxidation dyes, then the formula in order to join after the stand Stir in the same container. Custom Made Swooper Flags
Oxidation of a good aluminum substrates, the good version with a good paste and system . is completed, after the water wash away the paste to dry the printed material floating objects, and then closed in boiling water. And then dried, cut to shape, to complete the entire system of licensing work.
