- Around the earth is an atmosphere that is about 1,000 kilometers thick. The atmosphere consists of nitrogen, oxygen, carbon dioxide and other rare gases, as well as water vapor and dust. The atmosphere has reflection, absorption and scattering effects on electromagnetic waves. When the sun 150 million kilometers away from the earth hits the earth's surface, most of the energy disappears, leaving only a part

- The projection screen and the projector are a whole and complement each other. Therefore, the maintenance of the projection screen that is matched with the projector must be paid equal attention. Below I introduce the common sense of maintenance of the projection screen:
- Depending on the type and material of the projection screen, pay attention to different maintenance methods.
- 1.Most metal curtains and glass beads curtains have the characteristics of mildew resistance, fire resistance and cleanability. However, it is necessary to pay attention to prevent excessive dust and excessive moisture. The best cleaning method is to gently clean with a soft brush Too much washing will reduce the gain of the screen.
- 2. For glass-beaded screens, there are usually some threads or vertical lines on the surface. It is best not to wash with water. Try to wipe with soft cloth and chicken feather broom along the lines and clean from top to bottom. Large, so as not to damage its texture, if necessary, can be wiped with a damp cloth, wipe the surface gently, and dry in time.
- 3. Regardless of whether it is a manual screen or an electric screen, the screen should be rolled back into the protective box when it is not needed. After each use, check the surface of the curtain for dust or dirt. If found, wipe it with a soft cloth and roll the curtain into the protective box. The screen can be used often, but the continuous use time can not exceed 5 minutes, otherwise it will cause the motor to heat up. If continuous use is required to wait until the motor has cooled down, no additional lubricant is required for the motor.
- There are other points to note:
- · When rolling the curtain into the metal case, check the surface of the curtain to ensure that it is free of dust and foreign matter before rolling it back.
- · The curtain can be used often, but the continuous use time can not exceed 5 minutes, otherwise it will cause the motor to heat up.
- When using continuously, wait until the motor has cooled down before using it.
- · The motor does not need to add lubricant.
