Micronized waxes have good lubricating properties and can reduce the friction of inks during the printing process, thus improving the abrasion and scratch resistance of inks. For example, in water-based inks, the wax powder can prevent printed materials from sticking to each other when stacking, especially in high temperature environment, this property is especially important. Micronized wax can be used as a matting agent to reduce the gloss of the ink by the distribution of its particles on the surface of the ink, so that the printed matter has a matte effect. Micronized wax can be evenly distributed in the ink to improve the smoothness and feel of the coating. At the same time, it can also enhance the dispersion of pigment, so that the pigment coloring strength is increased. In oil-based ink, micronized wax can form a wetting film on the ink surface, making the ink surface smoother, more even and flat.

It can overcome the common causes of cable damage such as "pulling", "folding", "hanging", "smashing" and "squeezing", and can provide all-round protection for cables and water pipes. https://www.langno.com/cable-cleats/

Applicable to underground and ground coal mines containing explosive gas and coal dust: There are a large number of flammable and explosive components such as gas dust in coal mines, and there are many metal equipment and instruments. When the equipment is moved and used, it is very likely to collide with the cable hook, which will produce sparks and lead to explosions. However, the mining cable hook will not collide with the metal equipment to produce sparks when in use, ensuring the safety of underground coal mines. It is suitable for low-gas mines with an altitude of +1150m-1800m, an ambient temperature of -20℃ ～+45℃, and an earthquake fortification intensity of VIII. Major advantage Corrosion resistance: The flame retardant, corrosion resistant and antistatic materials are evenly distributed in the body of the mining cable hook, and the antistatic and flame retardant properties meet the coal mining industry standards. The humid and harsh environment underground will cause the steel cable hook to corrode and rust, which will increase the friction of the hook, resulting in increased friction, sparks are easily generated during friction, leading to combustion or even explosion. Due to its material characteristics, the mining cable hook can effectively avoid the above safety problems and is more suitable for the flammable and explosive working environment underground. Lightweight and easy to install: The steel cable hook is heavy, which will increase the labor intensity of workers and reduce work efficiency during use. The mining cable hook has low density, light weight, low cost, easy transportation and installation, durable and long service life. When used for underground installation, it can not only reduce the labor intensity of workers and improve work efficiency, but also reduce the overall cost of the project. Anti-aging and strong bearing capacity: The mining cable hook has good anti- aging performance due to the advantages of raw materials. It is not easy to become brittle in a humid environment and has good toughness. It absorbs impact force and can resist repeated impact. The maximum breaking force is not less than 3500N, and it has strong bearing capacity and can withstand loads for a long time. The force is not less than 160kg . When the arc hook bears a load of 50kg, the deflection of the straight rod section is less than 10mm. Compared with other hooks on the market, our company's hooks are slightly heavier and have better bearing capacity. Stable chemical properties: The mining cable hook is made of PVC material, and the flame retardant, corrosion resistant and antistatic materials are evenly distributed in the body. It has stable chemical properties and is resistant to alkali, alcohol, ether, hydrocarbons, weak acids, lubricants, detergents, water, etc. It is odorless, non-toxic, tasteless, and rust-free. It can be used in a variety of environments without changing the performance of the product itself. Low hardness: The hardness of the mining cable hook is lower than that of the metal hook, and will not cause damage to the cable when laying the cable. Anti-static: The arithmetic mean of the surface resistance of the upper and lower surfaces of the mining cable hook is ≤3×108 Ω. Flame retardant: The average value of the flame burning time of the alcohol burner of the mining cable hook is ≤3.00s, and the maximum value of the flame burning time is ≤10.00s; the average value of the flameless burning time is ≤10.00s, and the maximum value of the flameless burning time is ≤30.00s; the flame extension length after burning is ≤280mm. The average value of the alcohol lamp with flame burning time of the mining cable hook is ≤6.00s, and the maximum value of the flame burning time is ≤12.00s; the average value of the flameless burning time is ≤20.00s, and the maximum value of the flameless burning time is ≤60.00s; the flame extension length after combustion is ≤250mm. Wear-resistant and long service life: The mining cable hook has strong wear resistance. During use, it will not be worn due to friction and other problems. It can maintain working performance for a long time. Under normal use conditions, the service life can reach 50 years.

Non-metal rollers refer to industrial conveyor rollers made of non-metallic materials. Compared with traditional metal rollers, non-metal conveyor rollers have the advantages of flame retardancy, light weight, corrosion resistance, wear resistance, and low noise, so they have been widely used in modern industrial production.  The emergence of bulk non-metal rollers not only improves the operating efficiency of the conveyor belt system, but also reduces maintenance costs, providing strong support for the sustainable development of enterprises. In modern industrial production, high temperature rollers are important material conveying equipment, and their performance and quality directly affect production efficiency and economic benefits. In recent years, non-metal mining conveyor rollers have gradually occupied a place in the market with their unique technical advantages and product advantages, and have become the first choice of many companies. Major advantage Non-metallic oil-free rollers are a new generation of high-tech industrial mining supply developed by our company that use plastics instead of steel. The technical advantages are: a. The tube body is made of polymer composite material, which has the advantages of flame retardancy, high wear resistance, long life, non-magnetic, no adsorption of iron powder, dust and various sticky substances, low friction coefficient with the belt, self-lubricating, etc., which greatly avoids the defects of steel rollers and ceramic rollers, thereby greatly extending the service life of the belt and avoiding damage to the belt ; b. The design of non-metal rollers fully considers the use environment and user needs. It adopts an embedded combination design, which enables the roller to maintain better stability when bearing loads. At the same time, the bearing seat of the non-metal roller is closely connected to the cylinder, with a large load-bearing capacity, avoiding the problem of separation and scratching the belt during work, and improving work efficiency. In addition, the bearing seat of the non-metal roller is made of special materials, which is non-heat- conductive and high-temperature resistant, further improving the performance and safety of the product. The sealing structure adopts a double labyrinth design (after immersion test, the water inflow is almost zero) and precision assembly, which completely isolates the bearing from the outside world. It can effectively protect the bearing for long-term and continuous operation, and avoid dry grinding of the belt and roller skin caused by the bearing being contaminated and not rotating. At the same time, it replaces the traditional welding process, improves the concentricity, makes the equipment run more smoothly, and extends the service life of the roller. d bearing is a fully sealed maintenance-free bearing specially used for rollers, which has the advantages of flexible operation, long life and maintenance-free. Main function The main function of Langnuo non-metallic rollers is to support and transport materials. In the conveyor belt system, rollers are responsible for supporting the conveyor belt and keeping it running smoothly. With their excellent wear resistance and corrosion resistance, non-metallic rollers can ensure that the conveyor belt can still run stably in harsh environments and reduce the possibility of failure. At the same time, the lightweight design of non- metallic rollers also reduces the energy consumption of the entire system and improves energy efficiency.
