Molybdenum disulfide
It has a broad range of application and excellent properties, so much research has been conducted on its preparation and use at home as well as abroad.
Natural law
MoS2 may be prepared naturally, using the molybdenite concentrat purification method. The method involves removing the acid-insoluble matter (SiO2, Fe, Copper, and molybdenite) from a molybdenum concentration of high quality through physical and chemical action. The nano-MoS2 obtained is refined further to remove impurities, such as Ca and Cu. The nano-MoS2 produced by this method is capable of maintaining the MoS2 crystal form, it has good lubricating properties, and can be used to make lubricants. The nano-MoS2 that is produced using the natural method has a low purity, and purification technologies need to be improved. If the temperature of the atmosphere is less than 400, the lower-cost MoS2 is recommended. MoS2 offers a better lubricating effect below 1300 degrees.
Chemical synthesis
The synthetic method is able to prepare sulfides in different sizes and puritys, with less impurities. It can also be tailored to meet specific functional requirements. Synthetic methods have always been popular for producing nano-sulfides. There are a number of methods to prepare nano MoS2, such a thermal decomposition with ammonium, hydrogen sulfide, or sulfur, high energy ball milling, carbon nanotube confinement, hydrothermal synthesis, high energy physical method and chemical combination, among others. In general, there are only two preparation methods. You can reach nano-MoS2 directly by reacting either a tungsten, molybdenum or sulfur source.
Useful Information
As an effective anti-friction agent, molybdenum disulfide The raw materials of brake pads include four parts: binder, reinforcing fiber, friction performance modifier, and filler. Four parts make up the composition of brake pads: binder (binding agent), reinforcing fiber (reinforcement fiber), friction performance modifier (friction performance modifier) and filler. The friction performance modifiers fall into two different categories.
(1) Anti-friction material: Addition of this material can increase the material’s resistance to abrasion, reduce noise and reduce its coefficient of friction. These materials are primarily graphite (or molybdenum), lead, or copper.
(2) Friction material The friction coefficient can be increased by adding this material. Among the most common inorganic materials are metal oxides, some metal fillers and certain inorganic compounds. The friction modifier is mainly used to adjust the material’s thermal stability and working stability.
Molybdenum diulfide offers good dispersibility and wear resistance as well as noise reduction. Addition of molybdenum disulfide to brake pads has the following main functions:
Anti-friction: Molybdenum Disulfide processed through jet pulverization can have a particle size between 1.5-20 microns. It has an excellent dispersion and anti-friction performance.
Increased friction The friction temperature causes molybdenum dioxide to oxidize and form molybdenum trioxide, which expands when temperature increases. This plays a key role in increasing the friction.
Anti-oxidant, anti-falling and other: Molybdenum Disulfide is slightly alkaline. It protects the friction material from oxidation by covering the surface.
Expansion: The internal voids can increase when the friction material is heated to a high temperature. However, molybdenum oxide can compensate for this.
Reduce the specific gravity The specific gravity for molybdenum diulfide is 4.5 to 5.2. As the fineness increases the specific surface increases and the specific density decreases.
