WS₂ grease has good lubrication performance, and can still play a good lubrication effect on mechanical equipment in high temperature, high pressure, high vacuum and other harsh working environments. What are the reasons for this?

Gearbox is a very important part of the vehicles. Its performance is the key to measure the power, economy and drivability of construction machinery. The tungsten disulfide coating is used to treat the gearbox, which effectively extends the gearbox's service life.

The harm of tungsten disulfide to human body mainly comes from the tungsten disulfide powder produced in the process of crushing and grinding. It may cause harm to human body through inhalation, intake and skin or eye contact, causing lung damage, eye and skin irritation and other conditions.

Tungsten disulfide coating is widely used in automobile industry, medical equipment, plastic industry and other fields. It is favored by most customers. It has brought considerable economic benefits to the industries and enterprises, which is inseparable with its own advantages.

Tungsten disulfide has a hexagonal layered crystal structure -- the weak bonding between atoms in a single crystal layer and the weak van der Waal’s force between the crystal layers, which makes it both lubricated and conductive and accordingly has a wide range of applications in the field of solid lubrication and electronics.

With the improvement of science and technology level and the progress of human development level, environmental pollution is becoming more and more serious, toxic and difficult to degrade. Pollutants are more and more widespread in the air, which is harmful to biological safety and ecosystem, and restricts the progress of society.

With the continuous improvement of the power of electronic devices and the miniaturization of devices, the corresponding power density is also increasing, and the problem of heat dissipation is becoming more and more prominent, which puts forward higher requirements for the performance and reliability of heat sink materials.

With the rapid development of global industrial technology, environmental pollution has become increasingly serious, which has caused immeasurable harm to people's health and life. Therefore, photocatalytic technology has developed rapidly in recent years. Semiconductor catalysts have attracted extensive attention of scientists for their advantages of simple preparation, low energy consumption and fast degradation.

Traditional cemented carbide is composed of hard WC phase and low melting point metal bonding phase. WC has high hardness, excellent oxidation resistance and corrosion resistance. The addition of metal bonding agent will inevitably weaken the hardness, wear resistance, oxidation resistance and corrosion resistance of the alloy. In addition, it is likely to make the alloy more stable. The decrease of wear resistance, especially the softening and oxidation of metal bond at high temperature, will make WC cemented carbide prone to over-rapid failure, which limits the application scope of WC cemented carbide.

Tungsten oxide is a very good catalyst and high temperature superconducting material. It is also used to make electrochromic windows, infrared switches, writing, reading and polishing optical equipment, gas sensitive, humidity sensitive and temperature sensitive components. Meanwhile, tungsten oxide nanowires have excellent field emission properties and can be used as structural precursors for WS₂ nanotubes.
