A few key points in LCD electronic whiteboard maintenance

With the rapid development of multimedia applications, the use of liquid crystal electronic whiteboards has become more and more extensive. Then, for the daily care of liquid crystal electronic whiteboards, many users are not familiar with the correct cleaning methods, and it is easy to make the following mistakes: use soft Wipe cloth or paper towel, it is easy to scratch the LCD screen; clean the screen with water, it is easy to cause short circuit of the internal equipment of the monitor, and the water trace will remain on the screen, it is difficult to remove, affecting the effect of the LCD screen; clean with alcohol or other chemical solvents, Dissolving the special coating of the LCD screen seriously affects the viewing effect.

For cleaning LCD whiteboards, the company's professional LCD whiteboard manufacturers have the right way to clean them - use deer skin or high-grade glasses cloth to gently wipe the dust off. For fingerprints and oil on the LCD screen, use a cleaner dedicated to the LCD screen. When using detergent, also be careful to wipe from the center of the screen until the cleaning agent on the screen is wiped clean.

It is worth noting that during this process, do not allow water to flow into the interface of the electronic whiteboard screen and the screen frame to avoid short-circuiting of the display. Also, do not use a hard towel to scrub the surface of the electronic whiteboard screen to avoid rubbing the surface of the electronic whiteboard screen and affecting the display. Cleaning the display should be timed quantitatively, and frequent scrubbing is not correct, which will also have some adverse effects on the display of the electronic whiteboard. In addition, I have some secrets to deal with some oil stains that can't be wiped off. I use a transparent glue to stick it on the screen, and then peel it off. The place where the screen is pasted is very clean, and the oil stains are glued to the transparent glue.

1, to avoid the internal burning of the electronic whiteboard screen

CRT displays can burn out due to long-term work, as well as LCDs. So be sure to remember that if you don't use it, be sure to turn off the display or lower the display brightness of the display. Otherwise, it will cause internal burnout or aging. Once this damage occurs, it is permanent and cannot be recovered. So be sure to pay enough attention. In addition, if a fixed content is continuously displayed for a long time, it may cause some LCD pixels to overheat, thereby causing internal burnout. To avoid this, take the following actions:

1) Please turn off the LCD touch screen display when it is not working.

2) often change the display content on the screen at different time intervals (such as running a screen saver)

3) reduce the brightness of the display to a darker level;

4) Display an all-white whiteboard screen content.

2, maintain the humidity of the environment

3. Correctly clean the touch screen surface

4. Avoid unnecessary vibration

The LCD whiteboard screen is very fragile, so avoid strong shock and vibration. The LCD whiteboard is almost the most sensitive electrical device in the user's home or office. LCD whiteboards contain a lot of glass and sensitive electrical components that fall to the floor or other similar strong blows can cause damage to the LCD whiteboard screen and the CFL unit. Also be careful not to apply pressure to the LCD display surface.

5, do not disassemble

One rule is that you should never disassemble an LCD whiteboard. Even after a long period of shutdown, the CFL inverter in the backlight assembly may still have a high voltage of approximately 1000V, which can cause severe personal injury. So never try to disassemble or change the LCD whiteboard display to avoid high voltage.

6, usually it is best to use the recommended best resolution

7, put an end to some bad habits

The biggest bad habit is to often point to the whiteboard screen by hand. The LCD touch screen display is very delicate, and the display of thousands of dollars should not be moved casually. Generally speaking, the liquid crystal display is relatively light, accidentally knocked down, this is not a joke. Another point to note is that the power consumption of the liquid crystal display is relatively small, but the voltage of the transformer behind the liquid crystal display is still very high; pay special attention to safety, do not open the back cover of the electronic whiteboard display under power.

As a modern teaching equipment, LCD touch electronic whiteboard is a modern educational equipment for multimedia teaching in multimedia classrooms. The use of information technology as the output of teaching methods not only makes modern classroom teaching more vivid, but also stimulates learning interest and better protection. Teachers and students have vision and make teachers and students healthier.

Conveying Machine, in a word, is a kind of machine to convey powder, small particles or granule from one point to another point. There are several different type of conveying machine: From conveying ways, we can distinguish horizontal conveying, inclined conveying and vertical conveyor. From the feeding material continuous ways we can distinguish into: even feeding, batch feeding, volumatic feeding. 

For example, conveying machine include:

Flexible Screw Conveyor: Flexible screw conveyor is flexible, allowing a multiple of configurations to suit application  requirements. The standard unit consists of an inlet, an outlet, a flexible spiral spring, a PPR  hose, a motor and a hopper.

Its design is very simple & eliminates the need for any additional operating equipment such as  filters or bearing. It consists of electric motor driven spiral, which is the only moving part,  rotates within a food grade & sealed tube.The material moves along the spiral within the tube. The unique action of the flexible spiral conveyor eliminates the risk of the product separation  that can take place in conventional pneumatic conveying systems where mixed materials have  components of different densities and particle size.In fact,the conveying action ensures constant remixing.Conveyor maximum length can be upto 15 meters for material bulk density 0.6 kg/ litre and may be increased or decreased inversely with bulk density.Vertical installation are also possible,but carrying capacity  decreases with increase in angle of inclination. Feed hopper is  available in standard size or according to customers specification.

Vacuum Conveyor: The vacuum conveyor machine can reach the objective that feeding materials with safe and convenient can't cause some dangerous factors for the operators, It mainly consists of vacuum pump(no oil and water),oil and water separator, stainless steel suctiontube, flexible hose, PE filter or SUS316 filter, compressed air cleaning device, pneumatic discharging device, vacuum hopper and automatic level control device. This machine can reach GMP standard and is the ideal feeding to food industry and pharmaceutical industry.

Remarks: we have two kinds of vacuum conveyor machines for electrical vacuum conveyor and pneumatic vacuum conveyor. The working process is almost same, but the electrical vacuum conveyor is replace the vacuum generator for electrical pump. You can choose the vacuum conveyor according to real situation
