Is stainless steel fiber expensive? What are the functions of stainless steel fibers

The first stainless steel fiber is generally determined according to the material of the fiber, the thickness and how many fiber filaments there are in a bundle, and the production process of each manufacturer is different. Ultimately, it's up to you to see if your use meets the requirements. 260 yuan kg--850 yuan kg range.

b a, synthetic plastics belong to organic synthetic polymer materials, so a is correct; B. Cotton is a natural material, not a synthetic fiber, so B is wrong; c. Stainless steel is an alloy and belongs to metal materials, so C is correct for burning; d. Degradable plastics can be decomposed by microorganisms in nature, so they can effectively solve the problem of "white pollution".

The internal structure, physical and chemical properties and surface properties of stainless steel fibers have undergone significant changes in the fibrosis process, stainless steel fibers not only have all the advantages of high elastic modulus, high bending and tensile strength inherent in metal materials, but also have some special properties and wide uses of non-stainless steel fibers.

Compared with organic and inorganic fibers, stainless steel fibers have higher elasticity, flexibility, flexibility, adhesion, abrasion resistance, high temperature resistance, corrosion resistance, better ventilation, electrical conductivity, magnetic conductivity, thermal conductivity, self-lubrication and sintering. At the same time, the unique environmental protection and reusability of stainless steel fiber have greatly improved its use value in social production and life.

With the many advantages of stainless steel fiber, stainless steel fiber has been widely developed and utilized in electronics, chemical industry, machinery, military, textile, food, medicine and other industries, and has opened up broad application prospects. Taking the textile industry as an example, at present, stainless steel fiber wire is mainly used in the production of metal fiber radiation protection clothing, Jingqi metal fiber radiation protection clothing is the third generation of radiation protection products in the development history of radiation protection clothing, it uses stainless steel metal fiber and cotton fiber blending process, that is, the metal is drawn into a filament, forming a network structure inside the fabric.

Ferromagnetism, electrical properties, surface treatment, coefficient of friction, versatility of stainless steel fibers.

Ferromagnetism of stainless steel fibers:

With the decrease of fiber diameter, the saturation magnetization is increasing, and with the decrease of fiber diameter, the martensitic phase content is increasing, and the intensity of its characteristic diffraction peak is also significantly increased. After the grain size is reduced to a certain extent, the exchange coupling between the grains makes the remanence enhancement, the coercivity decrease, and the permeability of the material increases.

The reason for the weak magnetism of austenitic fibers may be the stress-induced martensitic phase transformation, and the main component of austenitic stainless steel fibers is also iron, or it may be due to the smaller the fiber diameter, the iron element in its structure is closer to the ferromagnetic spatial state. Within a certain range, as the filament diameter decreases, the magnetism increases, and the fiber is paramagnetic after annealing. The magnetic properties of pure austenitic fibers are relatively weak, and annealing can transform the fiber structure into a single austenite again, and its martensitic diffraction characteristic peaks are weakened or disappeared.

Martensitic phase fibers are more magnetic, and their strength exceeds that of nickel matrix.

Stainless steel fiber electrical properties:

The diameter of the fiber filament decreases and the resistivity increases; The decrease in the diameter of the fiber decreases the axial conductivity of the fiber and increases the resistance.

The diameter becomes smaller, resulting in phase transition, crystal sequence transition and magnetic transition, which affect the resistivity, and the crystal has orientation and texture phenomena.

Stainless steel fiber surface treatment:

Stainless steel fiber production process, copper plating, tie head, pipe threading - wire drawing, annealing - acid electrolytic separation - cleaning and drying. In the acid hydrolysis and separation process, the DMJ03 system of Manjing technology is used to achieve rapid peeling, and the dispersion and passivation treatment are carried out simultaneously, and the finished product has strong anti-corrosion and anti-oxidation ability.

Coefficient of friction on the surface of stainless steel fibers:

The diameter of the fiber filament decreases, the friction coefficient increases, and the functional performance of the special fiber becomes more obvious. Theoretically, the paving surface is more uniform, and due to its special functionality, it may be necessary to change the spatial environment and processing technology of the paving process in order to better the material functionality.

Versatility of stainless steel fibers:

Conductive, anti-electromagnetic wave, sound absorption and insulation, filtration, antistatic, abrasion resistance, high temperature resistance, cutting resistance, etc.

Stainless steel fiber is a new type of industrial material, which not only has the properties of high electrical conductivity, high thermal conductivity, high strength, high temperature resistance, corrosion resistance, etc., but also has the characteristics of chemical fiber and synthetic fiber; At present, it is widely used in the industrial fields of petroleum, chemical, chemical fiber, electronics, textile, military, aviation, polymer material imitation, environmental protection and so on.
