The manufacturing process of NFJ Rust-Proof Foam Reinforced Metal Cotton is as follows: carbonize and rust-remove selected steel wool and perform passivation and anti-rust pretreatment; select small-mesh foam iron powder for reasonable grading; add carbon-based media materials and use special equipment Stir the above two materials thoroughly; add a medium-temperature (350°C) binder for the first sintering to remove carbon substances; select appropriate materials to retain and remove substandard waste; add reinforcing composite agents and sinter at high temperature.

 

Principle:

1、The porous structure achieves the following functions:

1.1 Adjusts the loose packing density between 1.0-2.0, closer to or the same as other materials, achieving uniform blending.

1.2 Absorbs noise in the pressure-friction state of the brake pad.

1.3 Large surface area improves heat dissipation, reducing the likelihood of high temperature causing metal embedding.

1.4 Deforms under heat and pressure, avoiding hard friction, reducing damage to mating parts.

1.5 Absorbs and dissipates pressure, raises the critical point of dynamic thermal energy conversion, avoiding sparks.

1.6 Organic fibers can be embedded in the material's pores, enhancing the overall strength of the brake pad.

2、Full iron-based material has good electrical conductivity, eliminating static electricity.

3、Rust-proof treatment ensures high rust resistance, eliminating the common drawback of easily rusting steel wool.

4、Precise composite ratios of various materials improve wear resistance and shear force.

5、Iron-based material is harmless to human health and the environment, demonstrating strong environmental characteristics.
