Multimedia projector is smooth whether clean will immediate impact reachs the road umbriferous picture, and use what dirt affects liquid crystal projector directly normally. Because dimension of liquid crystal board is lesser, be in commonly 0.5~1.5 inch, very small dirt is adherent can magnify above a lot of times, can form the stain with a lot of differ size on screen, camera lens looks more apparently when tone is ambiguous. And clean liquid crystal board compare difficulty again, because the polarizer of surface of liquid crystal board is organic high polymer film, unfavorable wait like banana oil, alcohol with organic dissolvent, can damage polarizer otherwise. Because the space is very little between liquid crystal board and polarizer, very hard method cleans here clean, what abroad uses is tall calm sb's anger sheds a law to clean, and home still does not have this equipment, if how is cleaned clean, this is to introduce a kind practical and simple method, also be the experience that we give in the summary in be being used for a long time.
Prepare a clean model bowl, clean clear water is put in the basin, the cleaner of right amount weak acidity is entered in the drop in water, had better be tableware scour, put assembly of all lens, liquid crystal board into water to immerse entirely next, with a compressed fine bamboo be in bamboo on tangle on cotton is extended enter swab gently between liquid crystal board and polarizer, other lens brushs a law with cotton, clear water of the reoccupy after be being washed rushs, can rinse a few times more, conditional but full of reoccupy distilled water, blow with hot hair drier next dry can. This kind of method is will liquid crystal board gets off alone will clean, but final coincide is more difficult, it is very difficult to do not advocate the personnel that does not have experience especially commonly its coincide. And of camera lens clean simpler, try with light graze of the paper that brush lens directly can, the dirt of the dirt inside machine and air channel brushs an edge to suck by the side of conditional usable cleaner, can prevent dirt effectively to fly upwards everywhere so. After the screen pack outside machine is cleaned with water, blow after working can, it is half month or a month are cleaned commonly, inspect working environment and decide.
3, the face-lifting processing of professional entrance machine and project machine
Because import projector and working projector its housing all by standard mould one-time casting model and into, in its surface is being used and carrying a process, extremely easy cut is mixed flyblown. As the accretion of its sales volume, will gradually halfway chance is returned, after wanting the old machine that returns its and breakdown machine processing, sell afresh, must undertake renovating handling to its, and the housing of this kind of machine uses maximum pressure electrostatic spray paint and gush model, it is commonly outside assist treatment. Must get off housing before sending face-lifting, prohibit will overall send, otherwise the circuit of easy attaint interior, do not make face-lifting processing commonly, but in-house light road must be cleaned, the place before its clean a method to be like is narrated.
