Beijing Jinke Composite Materials Co., Ltd. has a history of more than 20 years. The company has long been committed to the NFJ foam fiber porosity enhancing material for friction materials of brake parts for trains, automobiles and other industries, and NFJ inorganic high-temperature secondary binder. , NFJ inorganic high-temperature friction powder, NFJ non-rust iron powder research, development and production.

    Aiming at the problem of oxidation and rust of the ferrous metal powder material in the friction sealing material during use (will make the surface of the product easy to rust, produce flared flaking, affect the surface appearance and braking performance of the product. Braking or noise occurs And other issues). The company's scientific researchers conducted special research to find out the cause of oxidation and rust, and have obtained effective solutions. Now they have successfully developed non-rust iron powder.

First, the principle of preparation

    The principle is to use a variety of physical and chemical rust prevention technologies. During the smelting process, rust inhibitors are added at high temperatures to change the metallographic structure of the metal. Mechanical cooling is used during the granulation and crushing process. At the same time, inert gas is added. After high-temperature passivation treatment, the ferrous metal powder has achieved substantial rust prevention. The metal powder produced in this way can never rust, improve the quality of the friction seal material, and reduce the production cost. It is an ideal environmentally friendly product today.

Never rust

Third, the technical indicators

1.Appearance: black powder

2.Fe content: 68% ~ 74%

3.Fineness: can be produced between 100 days and 300 mesh

4.Water content: <0.8%

5.Loose density:

6, anti-corrosion performance: 5% NaCl solution, soak for 24 hours without rust spots

Fourth, instructions for use

    Users can choose the particle size of non-rusting iron powder according to their own formula, and the product has better dispersion performance during mixing. In this way, a good metal heat dissipation net is formed, which has a good effect on heat dissipation performance, high temperature resistance, wear resistance, impact resistance and noise reduction during the use of friction dense materials.
