The following on the use of screen printing glue technology, glue selection, screen selection and glue thickness, printing design, glue drying, etc.(a) use technology to use screen printing glue principle is very simple, just like ink screen printing, screen printing glue through the silk screen printing technology, the glue coated on the substrate to joint accurately, after waiting for glue to dry up, will produce a layer of dry film like tape, after can be real-time joint material end to the other side, or mounted on a layer of the debonding paper, in order to use in the future.(2) choose the screen printing glue now most of the screen printing signs or panels, are mainly plastic, such as polyester, PVC, ABS, PC film.The use of glue paste this kind of screen printed plastic, must choose no corrosive glue, so as not to damage the plastic surface or erosion of screen printing ink, water-based glue is the best choice.Another advantage of water-based glue is that it does not contain organic solution, will not release harmful gases, and does not burn, no fire and other potential environmental damage, in line with the current environmental protection and ISO14000 industrial standards.It is also convenient and safe for storage.(3) screen selection and the thickness of the glue screen printing glue glue coating location and weight greatly depends on the screen selection and pattern design.At present, the general manufacturers are using polyester or nylon mesh, take its economy and high water resistance, there are manufacturers using steel mesh, in order to obtain more precise, uniform and high stability effect.Screen printing glue after drying thickness and coating area also according to the selection of screen type and mesh.Normally, glue is about half as thick when it dries as it was when it was wet.At present, most of the silk screen manufacturers choose #23 to #39 (per cm) or 60-100 (inch) mesh, but if you want to achieve more accurate and clear pattern printing effect, you can choose a higher number of mesh.However, high density mesh, the printed glue thickness will be relatively thin.As for glue thickness, the base material with rough surface will be thicker, and the base material with smooth surface will make the glue thinner.Generally, the thickness of the screen printing glue will be affected by the following factors: 1. The screen mesh (2) the thickness of the sealing retinal/plasma (3) the design of the printing design 4. Glue the solid content of 5. Glue bonding degree 6. Screen printing speed of 7. 8. Glue scrape Angle glue scrape the hardness of 9. The surface of the substrate (4) printing pattern design of general printing available flooded immersion (commonly known as the earth) printing, is printing the pattern on the substrate.If the pattern to be printed is more complex, or the glue to be printed is a little thicker, we can use linear (commonly known as zebra crossing) or dot (commonly known as dag zi) printing.(5) the dry water-based screen printing glue sex screen printing glue dry is influenced by temperature increase and accelerate, SP7533 screen printing glue, for example, if you use 100 # steel net, dry time, about 30 minutes at room temperature, about 15 minutes under 50 ℃, screen printing, also can use infrared lamp or the glue dries up with hot air conveyor belt;Drying rate also due to different substrate and deviation.
