Organic glass screen printing manufacturer sign photosensitive glue in the making

Organic glass screen printing manufacturers introduce the sign of the photosensitive adhesive emulsion is one of the panels made of common materials, due to the use of sensitive glue material technology is more difficult to grasp, prone to bubbles or different levels of problem such as pinhole, - in the following - - - - - - > organic glass screen printing manufacturers introduce the sign of the photosensitive adhesive emulsion is one of the panels made of common materials, due to the use of sensitive glue material technology is more difficult to grasp, prone to bubbles or pinhole problem of different level, such as the organic glass screen printing manufacturers to introduce about sign in making this kind of problem solving: a bleb pinhole, the sign of the surface of the photosensitive glue. 1. Substrate surface is too dirty to sensitive glue affect production. 2. Silk screen causes page clean enough, not clean oil or removal. 3. Printing in the printing speed is too fast, the knife is not sharp. 4. Ink viscosity is high, there is no reasonable use thinner. Second, the surface of the adhesive film or indentation condition 1. Preliminary drying temperature low enough, and no blast drying oven to sign making photosensitive glue appear this kind of situation. 2. Long exposure time lead to higher temperature heat, exposure equipment malfunction or vacuum pressure cause this kind of situation. Organic glass screen printing manufacturer introduces the photosensitive glue three, can't sign production development, go to the film difficult to 1. Baking time is too long, the temperature is too high or oven failure affect sensitive glue effect. 2. Ink expired or improper dilution ratio affect the use. More than four, sign production enhancement incomplete glue 1. Use concentration enough developer or developing low temperature, pressure is not enough. 2. After preliminary drying temperature, time is long, roasted placed for a long time. After preliminary drying placed too long 3. Used by the ink expires, or after printing without baking or place a long time. 4. A longer exposure time lead to network adhesion, film problem can also lead to failure.
