Boride-based powders are commonly used in thermal spray applications due to their high hardness, wear resistance, and thermal stability. Some commonly used boride powders for thermal spray include: Boride Powder,Nickel Boride Powder,Chromium Boride Powder,Thermal Spray Materails Luoyang Golden Egret Geotools Co., Ltd , https://www.xtchvaf.com
In addition, other reasons that cause the full-color LED display screen are also provided for your reference:
1. Boron Carbide (B4C): Boron carbide is one of the hardest materials known, making it ideal for applications requiring high wear resistance. It also has excellent chemical resistance and thermal stability.
2. Titanium Diboride (TiB2): Titanium diboride offers a combination of high hardness, excellent wear resistance, and good thermal conductivity. It is often used in applications where both wear and heat resistance are required.
3. Tungsten Boride (WB): Tungsten boride powders have high hardness, excellent wear resistance, and good thermal stability. They are commonly used in thermal spray applications for their ability to withstand high temperatures and resist wear.
4. Chromium Boride (CrB2): Chromium boride powders offer high hardness, wear resistance, and good thermal stability. They are often used in thermal spray coatings for applications requiring resistance to abrasion and erosion.
These boride-based powders can be used in various thermal spray processes such as plasma spraying, high-velocity oxy-fuel (HVOF) spraying, and detonation gun spraying to provide protective coatings on surfaces that require enhanced wear resistance and thermal protection.
If the new screen is powered on, it may be that the control card settings are not scanned correctly, or the cable is not plugged in (check the cable from the control card to the first board). This problem can also occur when the 5V power supply is connected incorrectly.
If you suddenly find this phenomenon after using it for a while, in addition to the control card failure, the biggest possibility is that the board is flooded with water or a power supply.
Also try to connect the display of a DVI interface first, see if the DVI output port of the graphics card is normal. In the case of a general meteor shower card, the resolution of the DVI interface is 1024*768. The cause of the LED display screen may also be a problem with the graphics card, or a driver problem. Try to unplug the network cable of the receiving card behind the display and press the debug button on the receiving card to see if the screen scan is normal.
1, LED display screen can not be displayed
Solution: Check if the power supply of the electronic display is normal, and if there is a 220V power input.
2, LED electronic display is not normal, flower screen
Solution:
(1) Whether the LED control card parameter setting is correct, and whether there is any signal transmitted to the electronic display LED control card;
(2) Whether the communication line is communicating normally, check whether the LED control card has signal input;
(3) Whether the 5V power supply of the LED control card is normal;
3, the electronic display part of the screen display is not normal, such as black screen, flower screen
Solution: Check whether the screen power supply showing abnormality is working normally; the signal transmission line is faulty; the single module of the screen body is faulty.
A. There is a problem with the output.
1. Check whether the line from the output interface to the signal output IC is connected or shorted.
2. Check if the clock latch signal of the output port is normal.
3. Check if the cascaded output data port between the last driver IC is connected to the data port of the output interface or is shorted.
4, the chassis heat is not good, resulting in increased graphics card temperature.
Solution: Eliminate heat dissipation problems.
Check whether the fan is running normally, refuel the fan, clean the dust inside the chassis, and solve the heat dissipation problem.
5, reinstall the system, graphics card or display does not support high resolution.
Solution:
(1) Restart the computer, press F8 continuously, in the advanced startup menu, choose to enter “Safe Mode†and press Enter to log in to the system, then enter the display settings under Windows. After selecting the 16-color status, click the “Apply†button and click “OKâ€. " button.
(2) Restart the computer. In the normal mode of Windows, enter the device manager, delete the graphics driver, and restart the computer.
Conference room / exhibition hall small pitch P1.667 p1.875 p2LED display how to buy?
Lianshuo Optoelectronics Co., Ltd. is a professional manufacturer of small-pitch ultra-high-definition LED display brands. Our small-pitch electronic screen products have the advantages of low performance, low failure rate, good color consistency, no color difference, and strong color reproduction. At present, the main small-pitch display models are: p1.2 p1.5 P1.66 p1.8 p1.9 p2.0, etc. P1.667 indoor small-pitch display (referred to as P1.66 electronic screen) has extremely high definition. The pixel spacing is only 1.667mm, and the number of pixels per square meter is as high as 380,000. The display effect can be said to be completely no less than ordinary home TV. The P1.66 full color display has bright colors and fine refresh rate, which is very suitable for meetings. Room video conference or exhibition hall display. But the problem is that the P1.666 LED electronic screen is relatively expensive, and the procurement cost may exceed many unit budgets. P1.875 full color display (referred to as P1.8 electronic screen) point spacing is 1.875mm, one square meter pixel 284444, although the pixel is 100,000 square meters less than P1.66 display, but the display effect is unambiguous, even In the eyes of non-professionals, the clarity is only a fraction of the difference of P1.66. In terms of price, the P1.8 full-color electronic screen is nearly one-third cheaper than P1.6667. It can be said that the price/performance ratio is very high. If it is not very demanding for the LED large-screen effect, the individual still recommends p1. 875LED electronic splicing screen. P2.0 full color LED screen (referred to as P2 display) is the entry-level small-pitch LED electronic screen, and it is also a cheap and small-interval indoor display. If you want to buy a small pitch electronic screen, but the budget is not a lot, what should I do? P2LED display may be a good choice! Just like some people like Mercedes-Benz and BMW very much, but there is not much money on hand. In this case, it may be a method to choose an entry-level luxury car. Having said that, in the end, it depends on whether the budget is sufficient. If you don't have money, choose P1.6667led display!
