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 perform in dusty or dirty environments?

Leaf chains are designed to perform well in dusty or dirty environments, thanks to their robust construction and self-lubricating capabilities. In such conditions, chain components are exposed to various contaminants like dust, dirt, and debris, which can potentially affect the chain’s performance if not adequately addressed.

One of the key features that make leaf chains suitable for these environments is their simple yet durable design. With fewer moving parts and components, there are fewer areas for dirt and debris to accumulate, reducing the risk of chain jamming or clogging. The link plates of leaf chains are typically sealed to prevent contaminants from entering the pin and bushing joints, reducing wear and prolonging the chain’s life.

Leaf chains often incorporate self-lubricating properties, such as oil-impregnated sintered bushings or sealed pins, which help to maintain proper lubrication even in dusty conditions. This self-lubrication minimizes friction between the chain components, reducing wear and ensuring smooth operation, even in dirty environments.

However, it is essential to perform regular inspections and maintenance to keep the leaf chains in optimal condition. Cleaning the chains and removing any accumulated dirt or debris, along with proper lubrication, will help extend their service life and maintain their performance in dusty or dirty environments.

In summary, leaf chains are well-suited for use in dusty or dirty environments due to their simple and robust design, self-lubricating capabilities, and resistance to chain jamming or clogging. Proper maintenance is crucial to ensuring their reliable performance in such conditions.

Can leaf chains be used in heavy-duty lifting and rigging applications?

Yes, leaf chains are commonly used in heavy-duty lifting and rigging applications. Leaf chains are known for their high strength, durability, and ability to handle heavy loads, making them suitable for various lifting and rigging tasks in industrial settings. Here are some reasons why leaf chains are well-suited for heavy-duty lifting and rigging applications:

  • High Load Capacity: Leaf chains are designed to have a high load-carrying capacity, which allows them to lift and handle heavy loads safely and efficiently.
  • Durability: Leaf chains are made from high-quality materials and are constructed with precision, making them resistant to wear, fatigue, and damage from heavy lifting operations.
  • Compact Design: Leaf chains have a compact design, which makes them suitable for use in limited space or confined areas where larger lifting systems may not be feasible.
  • Flexibility: Leaf chains can be easily adapted to various lifting configurations and can accommodate different rigging setups, making them versatile for different applications.

These characteristics make leaf chains a preferred choice in heavy-duty lifting and rigging applications such as cranes, hoists, winches, elevators, construction equipment, and various industrial machinery. When using leaf chains for heavy-duty lifting, it is essential to follow manufacturer guidelines, adhere to load capacity limits, and perform regular inspections and maintenance to ensure safe and reliable operation.
