Basic knowledge of controlling surface dirt and scratches on light guide plates, provided by a light guide plate cutting manufacturer
Foshan Zhuohong Electromechanical Equipment Co., Ltd. specializes in light guide plate cutting services.
Why is the surface of the light guide plate easily soiled and scratched? Let the light guide plate cutting manufacturer analyze it for everyone.
The surface of the light guide plate is easy to adhere to dust, fingerprints and other dirt. If it rubs or collides with foreign objects, scratches will occur; in fact, this property is the same as ordinary acrylic. It's just that the light guide plate exports light from the inside under the action of the light source, and the dirt and scratches on its surface will be very intuitive, while ordinary acrylic does not have light guide performance, and can only be seen from the side carefully to see its surface dirt and scratches.
Below, the light guide plate cutting manufacturer will introduce the basic common sense of controlling surface dirt and scratches on the light guide plate.
1. Avoid processing and installing light guide plates in dusty workshops; be sure to install and process them in dust-free workshops.
2. After removing the protective film from the light guide plate, avoid touching the light guide plate with wet or sweaty hands;
3. Before removing the protective film from the light guide plate, the dust and debris on the surface of the light guide plate and in the installation structural parts should be cleaned;
4. Do not remove the protective film of the light guide plate too early. It should be removed before the installation of the light guide plate according to the processing process;
5. When handling the light guide plate, avoid arbitrarily rubbing or bumping the surface of the light guide plate; avoid sand leakage into the gap of the light guide plate at the original plate placement; when cutting the light guide plate, clean the foreign objects on the surface of the cutting bed;
6. Avoid wiping the surface of the light guide plate directly with non-cotton materials.
Common sense of handling dirt on the surface of the light guide plate: The main dirt on the surface of the light guide plate includes dust, fingerprints, and residual water stains during casting. The common sense of handling is as follows:
1. All the above dirt can be wiped off with an all-cotton fabric dipped in alcohol;
2. After wiping with alcohol, it should be air-dried or blown dry, otherwise, water will remain on the surface of the light guide plate, and bright spots will be produced after contact with reflective materials or pictures;
3. If the dirt on the surface of the light guide plate is not very obvious, it is recommended not to wipe it, otherwise, improper handling will produce new scratches;
4. If the light guide plate has static electricity, it is easy to attach dust, and it is not easy to clean; 1% soapy water can be used, and the dust can be easily removed by wiping with a soft cotton cloth dipped in soapy water to achieve a cleaning effect.
Common sense of handling scratches on the surface of the light guide plate:
1. Lighter scratches can be wiped with alcohol to reduce the effect of scratches;
2. Deeper scratches can be polished with an electric roller [cloth roller], which is a common method for acrylic products.
How to remedy the surface problems of the light guide plate that cannot be handled: If the dirt and scratches on the surface of the light guide plate are difficult to handle, or the handling work will affect the overall work efficiency; the following methods can compensate for the defects caused by the surface problems of the light guide plate on the product:
1. If there is a certain space distance between the display picture of the light box or display product and the light guide plate, the defects on the light guide plate will generally not be seen after the picture is installed;
2. For particularly light-colored pictures or pictures that are close to the light guide plate, a diffusion film must be covered on the defective light guide plate, which can generally completely compensate for the surface problems of the light guide plate;
3. There are various types of diffusion films on the market. If the light guide plate is particularly severely scratched, a thicker diffusion film can be used, which may affect the brightness of the light guide plate, but the brightness reduction will generally not exceed 15%.
