Solution To The Surface Bubbles Of Acrylic LED Backlighting Plate Screen Printing Ink

Solution to the surface bubbles of Acrylic LED Backlighting Plate screen printing ink

Acrylic LED on the back plate after the silk screen printing ink can appear sometimes bubble, bubble of the main causes of basically has the following several aspects: (1) acrylic materials such as dust adhered on the surface of the LED back plate, and oil stains. Screen printing ink itself has air bubbles or uneven viscosity. Screen printing is too fast or printing speed is uneven.

The intrinsic factor of the bubble is that because of the high viscosity of the ink, the ink surface tension is large, and the gas oil in the ink is difficult to escape from the ink film and stay in the ink layer. If the ink surface tension of ink viscosity is small, the bubbles will disappear by themselves, so there will not be the phenomenon of the printing of the printing ink.

It is usually possible to use the following measures to prevent bubbles in the ink layer: use a hydrophobic solvent. When the ink itself produces the air bubble, can add the appropriate anti-foaming agent in the ink. Acrylic LED Backlighting Plate If the ink is poor, when the screen printing plate is raised, the ink flow is relatively small, unable to fill the screen marks, not the surface smooth and smooth ink layer.

In order to prevent the appearance of screen after printing, the following method can be used: 1. It can be used for printing ink with slow drying, Acrylic LED Backlighting Plate increasing the flow time of ink and gradually solidifying ink. When making the plate, try to use a thin wire mesh.

Acrylic processing requirement for temperature: Acrylic LED Backlighting Plate acrylic sheet long using temperature is 80 ℃, high temperature will produce deformation. So try to save yakeli board under 50 ℃ environment.

Acrylic processing when these matters should be paid attention to in order to prevent the damage, scratches, roughly the same as the aluminum surface hardness of acrylic resin, although it belongs to a hard variety in the plastic, but must pay attention to when using scratch. To protect the surface, paste protective paper on acrylic resin. In use, in order to prevent the wound, adhesion dust, it is recommended that you use it as far as possible in the state of the protective paper, and then peel off. In addition, while working, please wear protective equipment, gloves, etc., while protecting your hands while protecting the surface. When removing the stain on the surface of the plate, use a soft cloth dipped in water or neutral detergent to clean it.

Considerations for adhesion of dust: if use dry cloth to wipe forcibly acrylic resin, will be charged by friction phenomenon, easy adhesion free of dust in the air and cause scars, please note. It is recommended that you use a soft cloth with antistatic agent or anti-static methanol, and gently wipe it.

Note to the line expansion: acrylic resin, like many plastics, has a linear expansion rate, which must be considered due to temperature variations due to temperature changes. Hope to be able to under the condition of constant storage and processing (using), if there is difference in temperature, in 20 ℃ temperature conditions, for example,Acrylic LED Backlighting Plate each 1 m length scale of about 1.4 mm.

Want to maintain an acrylic LED the brightness of the original back plate, there are acrylic LED back light care spray wax and cleaning and maintenance agent skincare product in two kinds of acrylic LED back plate. The former is mainly aimed at all kinds of wooden, polyester and acrylic paint, fire rubber sheet material LED back plate, and jasmine and lemon. Two different kinds of pure and fresh fragrance which are suitable for all kinds of wood, glass, composite wood or acrylic plate etc of real wood the LED back plate, especially for mixed material acrylic LED back plate. Acrylic LED Backlighting Plate So, if you can use both clean and care the effect maintain article, can save a lot of valuable time.
