Road safety driving must be familiar with common traffic signs

December 19, 2020

The main role of the traffic sign is to regulate and direct traffic. In general, the amount of traffic signs will not be too large. The driver only needs to see the traffic signs in advance. However, there are still many violations of the traffic rules. Many newcomers do not say that they will not recognize the traffic signs, but because the driver is excited and nervous, even when he is new, his face is dazzled. When the traffic signs and markings were on, some of the traffic in the brain was immediately returned to the coach. Now a simple introduction will be given to everyone by traffic sign manufacturers:
The guide sign is used to indicate the realm, the direction and distance of the town, the entrance and exit of the highway, and the location of the famous location. The color is blue (green) + white. This type of sign is most useful when drivers come to unfamiliar roads. They can help drivers locate and identify directions.
The warning sign is a sign that warns vehicles and pedestrians to pay attention to the dangerous place. Its color is a yellow bottom + black border + black pattern, and the shape is an equilateral triangle with the top corner upward. The color of this type of sign is very conspicuous, and it is usually set in locations where traffic is more complicated or in suburban areas.
The role of the indication sign is to instruct the vehicle and the pedestrian to drive according to the specified direction and location. The color is a blue background and a white pattern, and the shape is divided into a circle, a rectangle and a square. Indicators are very common on the roads. They can guide the driver in the right direction and lane to avoid violations.
The ban sign is a sign that prohibits or restricts vehicles. Except for individual signs, most of them are white + red circle + pattern red bar + black pattern. The ban sign is often combined with an electronic camera. When drivers see such a sign, they do not want to make a fortune. They can only follow the signs.
The four types of traffic signs, such as road signs, warning signs, direction signs, and prohibition signs, are the most common types. Digesting these information is enough to cope with traffic signs on the road. Effective methods include adjusting the driving mentality, training driving skills, cultivating a sense of direction, etc. You may wish to try new drivers.

Pyrite as Fillers Used in Grinding Wheels/ Abrasive Tools

Ablation grinding wheel / abrasive( filling agent )

PYRITE__As fillers used in grinding wheels/ abrasive tools

 

Place of Origin: Henan Luoyang, China

Pyrite, Iron pyrites, pyrites lump, Ferro sulphur, Pyrites powder.

Product Description

Detailed introduction:  is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.

Formation of a protective layer 
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.

4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2 
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2 

400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.

FeS2→FeS + S 
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).

(4)Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:
