Projector dust removal is a necessary operation to protect the service life and picture quality of the projector. During use, the projector will inhale a large amount of dust and other impurities, which will adhere to the internal parts of the projector, such as lenses, mirrors, and filters, resulting in blurred images, distortions, or color changes. If it is not cleaned and dusted regularly, it will seriously affect the use effect and life of the projector.

In addition, the projector dust removal is also to protect the health of the user's limbs. During the use of the projector, fine particles such as dust and bacteria will spread into the room through the air, causing potential harm to the human respiratory system, eyes and other organs. Regular dust cleaning of the projector can not only ensure the normal operation of the equipment, but also reduce the presence of indoor dust, bacteria and other pollutants, thereby improving the health level of users.

To sum up, projector dust removal is a necessary operation to protect the health of the equipment and users, and it needs to be carried out regularly. Professional dust removal equipment can be selected for dust removal operation or manual cleaning operation according to the instructions for use to obtain the best dust removal effect.

Projector. Cleaning method, divided into external and internal:

External cleanup

1. Lens: Slightly blow off the dust on the surface of the fuselage, you can go to the photography store to buy a professional dust-free cloth or blow a balloon to clean it, and then wipe the stains on the surface of the lens, wipe the lens with lens paper and alcohol, be sure to wipe it in one direction, and you can't wipe it back and forth or wipe it in a circle, which will cause damage to the lens coating.

2. Filter: You can use a brush to remove dust, and if the sponge block accumulates too much dust, it is recommended to soak it in cold water with professional cleaning agent for a few minutes, and then dry.

3. Fan: The exhaust fan can be used with a brush and a vacuum cleaner.

Dispose of it cleanly. The cleaning of the suction fan is more difficult, generally due to the installation position is not good to clean, it needs to be completely removed to be cleaned.

4. Body shell: plastic cleaner or anhydrous alcohol can be used.

The wipe is a softer non-woven fabric, which is still wiped in one direction, and the seams of the shell are cleaned with a cotton swab dipped in anhydrous alcohol.

Internal cleanup

Due to the complex internal structure, and some precision components need professional knowledge to deal with, and generally lose the warranty qualification after disassembly, it is recommended to send it to after-sales and let the manufacturer help clean up, which may require some costs.

1. The specific parts of the projector are cleaned and dusted: (1) Surface cleaning of the projector's liquid crystal panel, polarizer, dichroic lens, FBS lens, compound eye lens, reflector, lens and other components: (2) Cleaning of the inner surface of the projector bulb and the lamp surface lens; Residual (3) Cleaning of projector filters, fan blades and ventilation channels

4) Dust removal on the surface of the main circuit board, power supply board, lamp power board and signal interface circuit board. 2 Introduction to cleaning methods Physical cleaning method: firstly, use an air pump to remove primary dust on the appearance and interior of the whole machine, and then use advanced cleaning agents, special cotton swabs, and advanced lens paper for the optical path (such as liquid crystal components, lenses, etc.), and gradually destroy the surface of the lens to dust and clean, which will not damage the internal molecular structure of any lens.

But this method has very high requirements for the technical level of the operator, once the positioning of the liquid crystal plate and the lens is destroyed, there will be image dislocation of the gods, color edges and other phenomena, only assembly and debugging is the work that the general technical personnel can not successfully complete, so the optical path dust removal is a certain risk. For the circuit board, the surface dust is removed with an air pump first, and then cleaned with imported precision instrument cleaning agent, which does not cause any harm to the circuit board. Chemical Cleaning Method:

This method is often referred to as the ultrasonic cleaning method, the items to be washed are placed in a container containing chemical reagents, and the ultrasonic wave uses the huge energy generated by its unique wavelength to break up the dirt, decompose the substance, and achieve the purpose of dust removal. This energy is so penetrating that it is suitable for cleaning glass lenses and plastic parts, but cannot be used to clean special lenses and metal parts made of composite materials inside the projector. In particular, the LCD display unit is very afraid of the ruthless destruction of the crystal molecular structure caused by the huge energy generated by ultrasound, otherwise it will accelerate the aging of the LCD panel and the appearance of ghosting.
