What is the role of graphene and the uses of graphene The role of graphene

Fengtian Zhengxin Graphene environmentally friendly engine oil has low traction coefficient, low friction coefficient, excellent lubrication performance, high viscosity coefficient, good low-temperature fluidity, good oxidation resistance and thermal stability, and strong carbon removal and decontamination ability, which can make the engine get the best lubrication and protection.

The wear resistance of Fengtianzhengxin graphene environmental protection engine oil is more than 5 times that of ordinary engine oil, and the thermal conductivity is more than 3 times that of traditional engine oil, the use of Fengtianzhengxin graphene environmental protection engine oil can save fuel consumption by 5%-20%, improve engine power as a whole, reduce engine noise, automatically clean carbon deposits, oil sludge, can reduce harmful exhaust emissions by 80%, make exhaust emission detection easily up to standard, Chinese life insurance underwrites oil change cycle of 20,000 kilometers.

With modern production technology and enough attention to environmental protection, our company chooses castor oil instead of highly polluting mineral engine oil as the base oil, and adopts a unique suspension technology production process to successfully fuse castor oil and graphene. As a new material, graphene in motor oil has the characteristics of ultra-thinness, high strength (200 times the breaking strength of the world's best steel), and excellent thermal conductivity. Graphene's super wear resistance can reduce 75% of the metal wear of the car in the cold start state and prolong the engine life; Its super thermal conductivity can quickly conduct heat out and prolong the maintenance cycle of the vehicle; Graphene oil film can reduce the phenomenon of burning engine oil.

Castor oil has the characteristics of tough oil film, strong lubricity, strong penetration, high and low temperature resistance, good viscosity and temperature, non-volatile, green and environmental protection, which can greatly reduce friction and wear and protect the engine to the greatest extent.

Zhangjiagang Dao Kaile Environmental Protection Technology Co., Ltd. is the "Fengtian Zhengxin Graphene Environmental Protection Engine Oil East China Operation Center", the company pays attention to product quality and brand building, takes "Fengtian Zhengxin" engine oil as the fist product, and is committed to building "Fengtian Zhengxin" into a high-quality, high-tech, internationally competitive well-known brand, and constantly promoting the national brand "Fengtian Zhengxin" to the world.

Graphene is not only the thinnest of the known materials, it is also very strong and hard; As an element, it transfers electrons at room temperature faster than any known conductor.

1. Anti-rust: Since graphene will not be soluble in water, polymers can be mixed for anti-rust coatings. Graphene is insoluble in water and has ultra-high electrical conductivity, and if combined with steel, it can prevent steel from coming into contact with water and alleviate the electrochemical reaction of iron oxide to achieve an anti-rust effect.

2. Supercapacitors: Graphene capacitors can store more energy and have more times of charge and discharge. Capacitors can store electrical energy, such as the flash of a camera, which it relies on to provide energy.

3. Flexible electronic circuits: increase the computing speed of the computer by 50 times, and the most important material for computer chips is silicon. Graphene, on the other hand, conducts electricity better than silicon, uses less electricity, generates less heat, and can even eliminate cooling fans, and can be up to 50 times faster.

4. Speaker: The sound principle of this kind of speaker is that graphene produces sound through the heat energy generated by the transmission of electric current. If you put a layer of graphene less than one nanometer thick on glass and two types of plastic (two different types), and then apply alternating current, you can hear the sound.

Instead of vibrating through a diaphragm, this speaker emits sound through graphene transporting an electric current, and its biggest advantage is that it is thin and flexible, and can be made into any shape.

5. Water purification: The strong adsorption capacity of graphene can effectively control water pollution. The graphene filter element can filter out sediment, heavy metals, and chemical residues, and the sterilization rate can reach more than 90%, and the filtered water is sweet and delicious, and the service life is longer than that of activated carbon, which solves the trouble of frequent replacement of the filter element.

The application prospect can be done"Space elevators"According to scientists, graphite is easily found on Earth, and graphene is arguably the strongest substance known to man, and it will have many fascinating development prospects. It can not only develop and manufacture paper-thin ultralight aircraft materials, but also make ultra-tough body armor"Space elevators"The manufacture of cables opens a door"Alibaba"The Gate.

Photon sensors.

Graphene can also appear in the larger market as photonic sensors, which are used to detect information carried in optical fibers, a role that is still being played by silicon, but the era of silicon seems to be coming to an end. In October last year, a research team at IBM revealed for the first time the graphene photodetector they had developed, and the next thing people have to look forward to is graphene-based solar cells and liquid crystal displays. Because graphene is transparent, the electric board made from it has better light transmittance than other materials.

Other applications. Graphene can also be used in transistors, touch screens, gene sequencing and other fields, and is expected to help physicists make new breakthroughs in the field of quantum physics research. Chinese researchers have found that bacterial cells cannot grow on graphene, while human cells are not damaged.

Taking advantage of this, graphene can be used to make bandages, food packaging and even antibacterial t-shirts; Photoelectrochemical cells made of graphene can replace metal-based organic light-emitting diodes, because graphene can also replace the traditional metal graphite electrodes of lamps, making it easier**. This substance can not only be used to develop and manufacture paper-thin materials for ultralight aircraft, to make ultra-tough body armor, but even to make the 10,000-mile-long space elevator that scientists dream of a reality.

1. Anti-rust. Graphene is insoluble in water and can be mixed with polymers as an anti-rust coating.

2. Speaker.

Graphene makes sound by transmitting the heat energy generated by an electric current.

3. Supercapacitors.

Computer chips equipped with graphene supercapacitors are expected to obsolete batteries.

4. Clean up radioactive waste.

Graphene oxide particles combined with radioactive contaminants can make nuclear waste removal safe and cheap.

5. Flexible electronic circuits.

Silicon semiconductor chips give computers intelligence. It can process the binary ** of the basic units that make up digital information is 1s and 0s. Graphene has better electrical conductivity than silicon, it uses less electricity and produces less heat, so it is highly likely that graphene can process these 1s and 0s much faster than silicon.

6. Artificial muscles.

A layer of graphene fixed to the polymer wrinkles and stretches when an electric current passes through it.

7. Detect ** objects.

Graphene foam detects low concentrations.

Foam filters made of graphene can be used for DNA sequencing.

9. Bulletproof vest.

Graphene and carbon nanotube composite fibers have higher strength than Kevlar fibers, which are commonly used in the preparation of bulletproof vests.

10. Night vision.

Using a single layer of graphene as a negative and adding lead sulfide crystals to the negative, a night vision photodetector with high sensitivity and high flexibility can be made.
