Is the reversing radar useful? Can the novice reversing "artifact" depend on it?
1. Is reversing radar useful?
First: Is the parking sensor useful? Reversing radar is a relatively important auxiliary tool. Now there are many people who rely on the reversing radar completely, which can reduce a lot of unnecessary scraping and collision. So if the price difference is not big, it is recommended to buy a configuration with radar, such as a large price gap. It is recommended to buy one for yourself, very practical! !
Second: Because the rear window of some cars is not good, it is not easy to see. Now there are more parking spaces in the parking lot, and it is often necessary to move the car in a small space. For your own car, it is better to install one.
Third: There are two kinds of reversing radar: one is the ordinary reversing radar. Generally, it is based on the distance of your car's butt from the obstacle, and it sounds you, for example, the closer you get to the obstacle, the faster the sound it makes. . One is the visual reversing radar. You can see the scene behind the car in the car or see the distance of the car's butt from the nearest obstacle. There is a reversing radar. It is especially useful when the obstacles behind are not clear or there are moving obstacles behind. It is also a good tool for you to protect your car.
Second, the novice reversing "artifact" can rely on it?
Nowadays, almost every car is equipped with a reversing radar. Because of this, many car owners believe it unconditionally, which leads to many "traffic accidents". So is this article useful for reversing radar? The owner of the installation knows that it is quite useful, that is, there will be mistakes, so it is most important to practice your own reversing technology.
Today's reversing radar is quite popular, so the reversing radar is so popular? The reason is actually very simple, and now there are more newcomers and female car owners. It is understood that there are currently hundreds of reversing radar brands on the market, there are many varieties, useful digital display distance, and voice prompt range, and then advanced can be displayed in real time through DVD images, that is, reversing image monitoring system. But because the brands have different functions, the price is not the same.
According to the introduction of relevant people, the main criterion for judging the performance of reversing radar is the number of probes, which determines the detection coverage capability of the reversing radar. The more probes, the fewer the detection blind spots. There are 2 probes, 3 probes, 4 probes, 6 probes and 8 probes on the market. 2~4 probes are generally installed on the rear bumper of the car. The reversing radar of more than 6 probes can be extended to the front. Even the side of the body and other locations.
In the survey, more than 70% of netizens think that reversing radar is the most practical configuration, but don't trust it too much, because it will inevitably lead to mistakes that lead to your collision.
A car owner encountered a reversal of the reversing radar. Specifically, this kind of reversing radar that he installed in the car has been used for a while, and there has been no problem, so he is very relieved about the function of the reversing radar. One day, when he was reversing, he suddenly slammed, and the rear bumper of the car hit a stone pier, and the reversing radar also rang. After getting off the bus, I found that there was a stone pier behind the rear of the car, which was about 10 cm lower than the reversing radar. The radar was not detected beforehand.
An industry insider who sells reversing radars said that most of the reversing radar products on the market are normal because of the presence of probe residual vibration. He said that the "jurisdiction" of most reversing radars is actually very limited. Due to the position of the probe installation, obstacles above the rear of the car are generally undetectable by the reversing radar. Prompt consumers, when buying a car, some dealers love to reversing the radar to offset part of the price of the car, as a gift to the consumer. However, these reversing radars, especially the cheap reversing radars installed in mid- and low-end cars, are particularly vulnerable to blind spots in the detection range. It is best for the owner not to fully believe in the reversing radar. When reversing, it is best to get off the bus and see what obstacles there are.
I hope that consumers will remember that instead of relying on reversing radar, it is better to practice reversing technology. When reversing, whether or not there is a reversing radar installed, it is best to get off the car and look at the rear and left and right sides of the car. Pay special attention to obstacles such as large stones, steel pipes, fire hydrants and water pipes. Ditch or small river or something, these are even more dangerous. It should also be noted that in the process of reversing, not only the car is behind, but also the various directions of the car. If there are any passengers, it is most reliable to find the individual behind the car.
After reading this article, the owner should know that the reversing radar is not foolproof. The owner should believe in his own driving skills, so it is the safest guarantee to practice the reversing technology.

Graphite Block is a solid shape, which is usually made of artificial Graphite , graphite mould and so on. It also has small graphite blocks made of Flake Graphite , such as a carbon brush. Graphite is mostly powder, such as soil Graphite Powder , flake graphite and other powder.

Graphite blocks for silicon carbide furnace, graphite furnace and other metallurgical furnaces, resistance furnace for lining and conductive materials, and opaque graphite heat exchangers. Widely used in electronics, metallurgy, chemical industry, steel and other fields, the product quality is excellent, the performance is stable.


The function and use of high purity (isostatic pressure) graphite blocks

Production and processing of various materials, specifications of the graphite rods, graphite products, graphite block, graphite block, graphite plate, graphite tubes of rotary kiln, High Purity Graphite crucible, graphite ring, graphite boat graphite products, such as the opposite sex, with high temperature resistance, good thermal conductivity, melting high purity, strong corrosion resistance, long service life, etc. Create the graphite block of special rotary kiln in rotary kiln, including kiln head, kiln tail graphite block and Graphite Seal Block. With long service life, the attached impurity content is very few, with high volume density and strong anti-folding ability.


Graphite, graphite, soft, black grey; It has a greasy feel and can contaminate paper. The hardness is 1 ~ 2, and the hardness can be increased to 3 ~ 5 along the vertical direction with impurities. The proportion is 1. 9 ~ 2. 3. Scope of specific surface area is focused on the 1-20 m2 / g, under the condition of starvation, its melting point above 3000 ℃, is one of the most heat-resistant mineral. It conducts electricity and conducts heat.

There is no pure graphite in nature, which often contains impurities such as SiO2, Al2O3, FeO, CaO, P2O5 and CuO. These impurities often appear in the form of quartz, pyrite, carbonate and other minerals. In addition, there are water, asphalt, CO2, H2, CH4, N2 and other gas parts. Therefore, in addition to determination of fixed carbon content, the content of volatile and ash content must be measured.

The technological properties of Natural Graphite classification graphite are mainly determined by its crystalline form. The crystalline form of graphite minerals has different industrial values and USES.

1. Dense crystalline graphite:

Dense crystalline graphite is also called blocky graphite. Such graphite crystals are clearly visible to the naked eye. The particle diameter is greater than 0. 1mm, which is concentrated in 0.1-1m2/g than surface area, and the crystal is arranged in a disorganized and dense block structure. This kind of: the characteristic of graphite is high grade, the average carbon content is 60 ~ 65 %, sometimes reach 80 ~ 98%, but its malleable and slippery sex is not as good as flake graphite is good.

2. Special Graphite:

Graphene is widely used in industry and is used in almost every industry. Industrial use of synthetic graphite, or special graphite. According to its forming way can be divided into the following kinds.

1. Isostatic pressure graphite, the three high graphite that many people call, but not the third height is isostatic pressure.

2. Pressed graphite.

3. Extruded graphite, mostly electrode material.

(1) processing speed is faster: usually, graphite's machining speed can be 2~5 times faster than that of copper; The discharge process is 2~3 times faster than copper.

The materials are more difficult to deform: the advantages of the thin rib electrode are obvious. The softening point of copper is around 1000 degrees, which can be easily distorted by heat. The sublimation temperature of graphite is 3650 degrees. The thermal expansion coefficient is only 1/30 of copper.

(2) lighter weight: the density of graphite is only 1/5 of copper, and the large electrode can reduce the burden of machine tool (EDM). It is more suitable for use in large mould.

(3) smaller discharge consumption; Because the spark oil also contains C atoms, in edm, high temperature lead to spark came out of the oil C atoms are broken down, turned on the surface of Graphite Electrode form a protective film, compensate the loss of the graphite electrode.

(4) no burrs; After finishing, the copper electrode needs to be repaired by hand to remove the burrs. However, graphite processing has no burrs. It saves a lot of cost and is easier to realize automatic production.

(5) graphite is easier to grind and polish; Because graphite's cutting resistance is only 1/5 of copper, it is easier to grind and polish by hand.

(6) lower material cost and more stable price; Due to rising prices in recent years, and now isotropic graphite copper price is lower, under the same volume, the universality of toyotanso graphite products price is 30% ~ 60% lower than the price of copper, and the price is more stable, short-term price fluctuations is very small.

It is this incomparable advantage that graphite products gradually replace copper as the preferred material for EDM electrode.
