What are the extended applications of oil-impregnated nylon liners compared to nylon sheets?

Sep 04, 2019

Nylon sheet material was prepared by in-situ intercalation polymerization of nylon sheet graphite nano-conducting composite material. The room temperature conductive percolation threshold value is 0.75% (volume), which is much lower than that of conventional conductive particle-filled polymer materials. For 2. At O%, the room temperature conductivity can reach 10 ~ S / cm.

    The transmission electron microscopy of nylon sheet shows that the flake graphite has a large diameter-thickness ratio due to the exfoliation of graphite after high temperature expansion. The thickness of the sheet is further stripped into several tens of nanometers by in-situ intercalation polymerization. In situ ruthenium layer polymerization with the nylon sheet enables the graphite particles to be uniformly dispersed in the nylon sheet substrate, thereby resulting in a low bleed threshold and high electrical conductivity of the conductive plastic.

    The oil-containing nylon sheet is a new type of self-lubricating material formed by adding a lubricating oil additive to the nylon sheet base to uniformly distribute the oil droplets in the nylon sheet. The dry friction factor of oily nylon sheets is only 1/2 of that of steel-bronze. Moreover, it has small mass, good elasticity, high hardness, easy processing, high heat distortion temperature, high heat resistance and cutting ability, and is very suitable for replacing copper and zinc-based materials as bushings.

    The pulley bushing was made of oily nylon sheet material, and the bushing of the overloaded pulley of the door machine was replaced. Since the nylon sheet has a certain elasticity, the deformation caused by the pressure can be quickly recovered after the pressure is reduced.
