Most of the currently used projector adjustment tables are 3-axis and 6-axis adjustment tables. After a certain period of time, the raster drift will occur. It is necessary to re-adjust the mechanical adjustment to ensure that the display screen is not distorted and to avoid adjacent screens. Misalignment.
Adjustment of color
Currently used large-screen projector lamps are mostly UHP bulbs, in the use of projector bulbs after a certain period of time will appear different degrees of attenuation, will certainly affect the brightness of the projector, resulting in the color of the adjacent screen between the big screen And uneven brightness, thus affecting the user's visual effects. In this case, the color and brightness of the projector can be adjusted by the relevant software, thereby effectively ensuring the consistency of the large screen effect.
Projector lens cleaning
The lens of the projector is an important part of the projector, made of special optical materials, and will have a film on the surface of the lens. After a long time use, there will be some dust on the surface of the lens. If you do not clean it, over time, it will affect the life of the lens, and it will also affect the display effect of the projector.
Projector core light path assembly cleaning
The color wheel is an indispensable component of the DLP display technology, and it plays a key role in the stability of the system. Therefore, after a period of time, the component should also be cleaned. There is a micro-mirror inside the projector core and a light-pass ROD assembly.
Screen cleaning
At present, the large-screen screen has two kinds of glass screens and resin screens. The screen must be cleaned regularly during use to ensure that the screen is not deformed and does not affect the display.
Mirror cleaning
The large-screen systems currently sold are mostly designed for rear projection boxes, which can greatly reduce the thickness of large-screen cabinets, while also saving a lot of installation space for customers, and it is also beautiful. However, this type of box structure design must have a reflector in the box body. The reflector needs to have a reflectance of 98% or more. It belongs to a special product, and usually a reflection film is applied on the surface to meet the requirements. Reflectance requirements. However, the mirror will collect a certain amount of dust on the surface after being used for a period of time. If it is cleaned from time to time, it may be eroded by the dust on its surface to reflect on the reflective film, which affects the display effect.
Replacement of spare parts
Lamps are the necessary spare parts for large screens. Lamps themselves also have problems with their lifetime. The average service life is about 6,000 hours.
Feed additive is a small amount or a small amount of material added in the process of feed production, processing and use. Feed additive is a Raw Material for modern feed industry must use for strengthening basic feed nutritional value, improve animal production performance, guarantee the animal health, save feed costs, improve quality of animal products and other aspects have obvious effect.
Feed Additives are divided into Microbial Feed Additives and Chinese Herbal Feed Additives. Among them, the microbial feed additive is a kind of microbial product that replaces or balances one or more bacterial strains in the animal ecosystem. In a narrow sense, it is a kind of microbial product that can stimulate the growth of beneficial bacteria and resist the growth of harmful bacteria. Microbial feed Additives containing a large amount of beneficial bacteria (active lactobacillus, bifidobacterium, bacillus), compound enzyme, chelating peptide, mildew remover, etc., as the inside of livestock and poultry feed, can rapid reproduction, on the one hand, into the bacterial metabolites and gut endotoxin inhibits the growth of other harmful flora, on the other hand, it formed the normal microbial flora in the host, synthesis of main vitamin for host, provide nutrition and prevent the invasion of pathogenic bacteria.
