Molybdenum disulfide is the inorganic compound with the formula MoS2. This black crystalline sulfide of molybdenum occurs as the mineral molybdenite. It is the principal ore from which molybdenum metal is extracted. The natural amorphous form is known as the rarer mineral jordisite. MoS2 is less reactive than other transition metal chalcogenides, being unaffected by dilute acids. In its appearance and feel, molybdenum disulfide is similar to graphite. Indeed, like graphite, it is widely used as a solid lubricant because of its low friction properties, sometimes to relatively high temperatures. 

Structure and physical properties: 

In MoS2, each Mo(IV) center is trigonal prismatic, being bound to six sulfide ligands, each of which is pyramidal. The trigonal prisms are interconnected to give a layered structure, wherein molybdenum atoms are sandwiched between layers of sulfur atoms. [2] Because of the weak van der Waals interactions between the sheets of sulfide atoms, MoS2 has a low coefficient of friction, resulting in its lubricating properties. Other layered inorganic materials exhibit lubricating properties (collectively known as solid lubricants or dry lubricants) including graphite, which requires volatile additives, and hexagonal boron nitride. MoS2 is diamagnetic and a semiconductor. 


Use as lubricant: 

MoS2 with particle sizes in the range of 1-100 µ M is a common dry lubricant. Few alternatives exist that can confer the high lubricity and stability up to 350 ° C in oxidizing environments. Sliding friction tests of MoS2 using a pin on disc tester at low loads (0.1-2 N) give friction coefficient values of <0.1. 

Molybdenum disulfide is often a component of blends and composites where low friction is sought. A variety of oils and greases are used, because they retain their lubricity even in cases of almost complete oil loss, thus finding a use in critical applications such as aircraft engines. When added to plastics, MoS2 forms a composite with improved strength as well as reduced friction. Polymers that have been filled with MoS2 include nylon (with the trade name Nylatron), Teflon, and Vespel. Self-lubricating composite coatings for high-temperature applications have been developed consisting of molybdenum disulfide and titanium nitride by chemical vapor deposition. 

Filtermesh (filtermesh) is simply made of metal meshes with different meshes. Its function is to filter the molten stream and increase the resistance of the stream, thereby filtering out mechanical impurities and improving the effect of mixing or plasticizing.
With acid resistance, alkali resistance, temperature resistance, wear resistance and other properties; mainly used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries. The filter is divided into textile fiber filter and metal filter. Filters are installed on machines called filters to filter natural water and food.
Product Usage
1. Used for sieving and filtering under acid and alkali environment, oil industry as mud net, chemical and chemical fiber industry as sieve strainer, electroplating industry as pickling net ...
2. Used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries.

3. Used in air conditioners, purifiers, range hoods, air filters, dehumidifiers, and dust collectors, etc., suitable for various filtering, dust removal and separation requirements.

Metal rubber filter
The metal rubber filter is made of stainless steel wire. The raw material is stainless steel wire, which does not contain any natural rubber, but has a loose and capillary structure. It is particularly suitable for gas and liquid filtration under high and low temperature, large temperature difference, high pressure, high vacuum, strong radiation, severe vibration and corrosion.
Metal rubber filter has some characteristics of metal, such as corrosion resistance, high strength and impact resistance. At the same time, the metal rubber filter can adjust the filtering accuracy of the filter by using the thickness of the wire, the density of the metal rubber, and the thickness of the filter. When cleaning, it is easy to restore its original density, which is convenient for cleaning.
Ventilation filter
Nylon filter product features: It is made of PP fiber textile molding, which has the best acid and alkali resistance and corrosion resistance. It has low resistance and can be repeatedly cleaned. The economy is relatively high. In addition, it captures Long and short fibers and dust particles are easy to clean, the filtration efficiency is not affected by cleaning, and the impact strength is very good. It is the product of choice for our customers.
Metal filter
All metal filter products, I believe everyone understands that the metal filter uses multi-layer expanded aluminum foil or stainless steel mesh products. It is a special filter material for the filter. As a result, the multi-layer folding and expansion of the filter is arranged in different densities and pore diameters from coarse to fine, so that the object changes the flow direction multiple times when it passes through, increasing its efficiency.
Air conditioning filter
The air-conditioning filter has a concave-convex honeycomb structure, which can be widely used in sewage filtration systems and air filtration. It is easy to clean and replace multiple times and has a long-lasting effect. Moreover, the air-conditioning filter is easy to clean, and has been recognized by a large number of users and friends.
Coarse filter
Coarse-effect filter products are mainly used for coarse dust filtration and air filtration system pre-filtration.
When cleaning impurities during use, special attention should be paid to the stainless steel wire mesh on the filter element cannot be deformed or damaged. Otherwise, the filter is installed, and the purity of the filtered medium cannot meet the design requirements. Pumps, meters and other equipment can also be damaged.
