POM (Polyformaldehyde)
POM (Full-name: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised “Plastic Steel”, and has comprehensive excellent performances, such as: wear-resistance, high hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability. POM has widely applied in Automobile industries, electronic and electric products, commodity, pipeline & fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and other metals.
Except POM-H, is often copolymerized with ethylene oxide together, in order to avoid the melting of POM material in the high temperature. POM-H has the better performances than POM-C in its high crystalline, mechanical strength and rigidity. And POM-C has the better performances than POM-H in its low melting point, temperature stability, fluxion characteristic and machining capability.
Father more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-efficient of frication, good lubrication, wear-resistance, non- creepage resistance.
Automobile industries: POM has a large application in car industries, because the mechanical parts made by POM, which has the advantages of high mechanical strength, high hardness, good wear-resistance, low co-efficient of friction, easy to maintain, reducing cost and so on, can be used in cars instead of coppery half stalk and planet gear. It not only saving copper materials, but also improving service life. At the engine fuel system, components for hose valves and case cover of radiator, cooling fluid’s standby case, water valve, oil box’ cover, pump impeller, shell of gasification machine and accelerator pedal and so on.
Electronic and electric Industries: because of its lower power consuming, high dielectric strength and insulation resistance and electronic arc resistance, POM has widely applied in electronic and electric Industries, such as: shell of electronic spanner, shell of electronic scissors, shell of coal drilling machine ,handle of switch, parts also for phone, wireless recorder, video tape recorder, television, computer, electrograph, calculagraph, bracket of recorder tape and so on.
Agricultural machine: part of manual sprayer, joint and transport part of seeder, parts of milk machine, shell of irrigation and drainage, valve, joint and bush of water and so on.
Other field:
Pharmacy & packing Machine: transporting screw, planet gear, gear bar, chain wheel and cushion bar and so on.
Construction industries: water tap, window frame, wash pot, water tank, pulley for portiere, shell of water meter and tie-in of water pipe.

How do leaf chains handle reverse motion or anti-reverse requirements?
Leaf chains are designed to handle reverse motion or anti-reverse requirements in lifting applications. They offer a unique design that prevents the chain from backtracking, ensuring the load remains securely in place even during sudden stops or reversals.
The anti-reverse feature in leaf chains is achieved through their construction. Leaf chains consist of link plates connected by pins and retainers, forming a continuous loop. The link plates have a shape that allows them to interlock with one another, creating a self-locking mechanism.
When the chain experiences a reverse motion or tries to move backward, the interlocking link plates engage and resist the motion, effectively preventing the load from descending unintentionally. This anti-reverse capability is crucial for ensuring the safety of lifting operations and protecting both the load being lifted and the equipment.
In addition to their anti-reverse characteristics, leaf chains also offer smooth and quiet operation during forward motion, making them suitable for various lifting applications where controlled and precise movement is essential.
It is important to note that proper maintenance and periodic inspections are necessary to ensure the anti-reverse feature of leaf chains remains effective. Regular lubrication and prompt replacement of worn or damaged components can help maintain the chain’s reliable performance in handling reverse motion requirements.
In summary, leaf chains possess inherent anti-reverse capabilities due to their interlocking link plate design, making them suitable for lifting applications that involve frequent changes in motion direction while maintaining load security and stability.
What are the benefits of using a leaf chain in waste management and recycling equipment?
Leaf chains offer several advantages when used in waste management and recycling equipment. These applications often involve heavy loads, continuous operation, and challenging environments, making leaf chains an excellent choice for such equipment. Here are the benefits of using a leaf chain in waste management and recycling equipment:
- High Load Capacity: Leaf chains are designed to handle high loads, making them suitable for heavy-duty waste management equipment, such as balers, shredders, and compactors.
- Resistance to Wear: Waste management and recycling equipment operate in abrasive conditions due to the presence of debris and recyclable materials. Leaf chains are made from durable materials and can withstand wear and tear, ensuring a longer service life.
- Reliability: Continuous operation is often required in waste management and recycling processes. Leaf chains are known for their reliability, providing consistent performance under demanding conditions.
- Compact Design: Leaf chains have a compact design, which is advantageous in space-constrained waste management facilities, where equipment needs to be efficient and easy to maneuver.
- Cost-Effectiveness: Leaf chains offer a cost-effective solution for waste management and recycling equipment, providing excellent performance at a reasonable price point.
- Resistance to Corrosion: Waste management and recycling environments can be corrosive due to exposure to moisture and chemicals. Leaf chains with appropriate coatings or materials can resist corrosion, ensuring longevity and minimizing maintenance requirements.
Leaf chains play a crucial role in the reliable and efficient operation of waste management and recycling equipment. However, regular maintenance, such as proper lubrication and inspection for signs of wear, is essential to ensure optimal performance and safety. Following the manufacturer’s recommendations and guidelines for chain maintenance will contribute to the longevity and reliability of the leaf chain in waste management and recycling applications.
