Teach you to clean the projection screen
Small pieces of non-wetting stains, using an eraser
When there are relatively small pieces of non-wetting stains, a better method is to gently wipe them off with an eraser. However, if the rubber is not of good quality or a colored eraser, it may not be completely erased and leave a blank mark. Therefore, pay special attention to the use of pure white high-grade rubber, which is easy to buy in stationery stores. As for the method of erasing, I would like to know what to do when I recall the warmth of my homework.
Liquid stains or stains are large, use detergent
First, make sure that the pH of the cleaner is as neutral as possible. Because the screen base layer and coating, most of which are resin or rubber materials, are susceptible to corrosion and discoloration.
Second, do not use oily cleaners and brightener cleaners such as Bi Lizhu. Water-based, volatile foam-based cleaners can be used, and there is no damage to the screen. You can also choose one of the cleaners in the supermarket's collar.
Finally, it is important to know what tools to use when cleaning the projector screen. Because the surface of the curtain is actually uneven, it is necessary to select an erasing tool with as small a molecular particle as possible, such as a polymer sponge. The sponge particles are very small, and the sponge can be sufficiently removed after the cleaning agent softens and softens the dust. Dust in the pit. On the contrary, using a rough sponge or towel, it is difficult to clean the small stains into the concave of the curtain.
Oily stains, using cotton balls, a small amount of degreasing solvent
This situation is more difficult to deal with, and if handled improperly, there is a great risk. Only use a small amount of degreasing solvent on the cotton ball first, and then quickly wipe it off, then dilute with more pure water or neutral detergent and blot it as soon as possible. However, for some special stains, especially at some evening parties, there are no effective cleaning methods for the colored stains that are sprayed up. So before this lively scene appears, it's best to take care of your projector screen to avoid hanging.
Glass bead curtains can't be cleaned
Commonly used projector screens can be divided into white plastic screens, glass bead curtains, metal curtains, etc. according to the curtain material. In general, in addition to the glass bead (Glass Beaded) does not have the clean characteristics, other screen materials can basically choose the appropriate cleaning method according to the degree of fouling.
The bead curtain is widely used because of its high gain and moderate price. However, the bead curtain material, because of the surface of a fine quartz coating, the stain easily invades the gap between the particles, it is difficult to clean up. In addition, the surface of the quartz crystal itself is also very easy to stick to the stain, that is, secondary pollution occurs. Therefore, when using the screen of the glass bead curtain, you should be extra careful and caring, and it is best to close it in time when not in use.
