Epoxy signs manual
Epoxy signs of manual operation:???????Epoxy plate manual operation is different from Epoxy plate machining (For more see "Epoxy signage Operating Procedures"), to distinguish between specific request from for comparison.1, the first ready for all kinds of substrates, such as: nameplates, badges, medals, etc. into the oven preheating temperature requirement of 60 degrees, the purpose of the removal of surface moisture.2, the substrate was placed flat dehumidified consistent level of console board waiting drip.3. The amount, take a clean beaker, accurate measurement, the B component, a 2: 1 weight ratio of mixing evenly (must be mixed, otherwise there will be sticky and with the substrate surface delamination phenomena , the manufacturers of the products are the same to do this). (Note: the proportion of the manufacturers are not the same, as the case may be).4, and then with a good mixture into a vacuum oven, open real pump, removing bubbles mix in a vacuum.5, take in the clean needle, the needle after defoaming Shuijingjiao suction tube, then measure and drip evenly in the prepared substrate (ie: signs, trademarks, etc.) of the surface, the general crystal layer thickness 2mm, let the natural leveling can be (Note: The above process is controlled within 30 minutes, so as not to increase the liquid viscosity, resulting in inoperable).6, the substrate 3-5 minutes after instillation Shuijingjiao observe glue surface without bubbles or dust particles, if any small bubbles, usable pin to pierce, found dead have not stream Shuijingjiao to place, with Extradition can pin.7, pouring good signs, at room temperature 20 ℃ -30 ℃ cured 10-24 hours harden, becoming left the surface of the crystal plate.8, in case of stickers, trademarks, etc., in itself is very thin, and the boundary is not obvious, when pouring, likely to cause Shuijingjiao spill to reach 2mm thickness will be difficult, so make Shuijingjiao grasp different situations, control viscosity, In the application process, you can put 1-2 hours in order to increase the viscosity, adapt thin Shuijingjiao casting.9, making more than 2mm thick crystal glue signs, can be divided into secondary Epoxy, after the first dispensing, curing for 3-5 hours, then dropping layer.10, Epoxy after cleaning, regardless of manual dispensing, or automated dispensing, after the completion of the machinery, equipment, containers are required to clean, because the Shuijingjiao hardened, insoluble in any solvent, therefore it must not harden before the machine , the containers are required to clean (Recommendation: Use acetone or ethanol)
Aluminum signs, classification and production
?In the classification of signs, aluminum signs (the aluminum plate) occupies a part of, and aluminum have their own brand in their own classification, in simple terms, is divided into three types: black silver word, silver face black, silver at the end Silver word. As for the other colors of signs, nameplates do not belong to Al licensing category.???????Al licensing production and other production processes signs have in common, there are differences between the law, we look at the following specific description:First, the bottom of the color production methods. ⑴ oxide (such
