As mentioned above, boron is an important chemical raw material. The main use of boron ore is to produce borax, boric acid, elemental boron and other compounds of boron, which are widely used in many sectors of the national economy.
1. Building materials industry
The glass industry is the largest user of borax. The addition of a certain amount of borax to the glass production can enhance the thermal stability of the glass, increase the transmittance of ultraviolet rays, and improve the transparency and impact resistance of the glass. In recent years, boric acid has also been widely used in the manufacture of glass fibers, which are not only important raw materials for the production of FRP, but also new materials for construction, machinery and naphthalene industry.
Borax is used as a catalyst in the ceramic industry. Borax is also an additive for the production of preservatives, high temperature crucibles, paints, etc.
2. Light industry
Borax is an important raw material for the production of enamel products. It can enhance the firmness and gloss of enamel products, improve the heat resistance of enamel, and greatly increase its expansion coefficient.
In the printing and dyeing industry, borax is a commonly used scouring agent to remove oil, wax and pigments contained in natural cotton fibers, and has bleaching effect on the original cloth to facilitate dyeing.
Borides in the paper industry is a new paper coating, it can increase the gloss and fire properties of the paper, and the like used for processing mercury-containing waste water in the paper industry.
Certain compounds of boron can also be used as fire retardants, fire retardant coatings, paint desiccants, antirust paints, and the like.
3. Metallurgical industry
In the metallurgical industry added boride may be made of special steel, boron steel, such a steel having high strength and excellent corrosion resistance and heat resistance properties, are the main components for producing high-quality steel jet engine or the like.
Adding a little boron to metals such as aluminum , molybdenum , and nickel can improve the mechanical properties of these metals. Boron is also an antioxidant when casting magnesium and its alloys. Iron , boron, silicon amorphous metal is a high-tech material, used as a transformer core, instead of silicon steel sheet, can save 3/4.
4. Machinery Industry
In the machinery industry, boron is used for grinding, grinding, drilling and polishing of hard materials such as cemented carbide and gemstones .
“Boronization†is a new process in the machining industry that improves the hardness, wear resistance and oxidation resistance of the surface of the part.
5. Chemical industry
Borax and boric acid can be used as additives for daily chemical products such as soaps and detergents. The boron-containing detergent has the properties of protecting hair, strong detergency, and no pollution. Some borides may also be made good reducing agent, the catalyst, bromide, and the like.
6. Electronics Industry
Among the boron series compounds, some borides are insulating materials, and some borides are good conductive materials, have semiconductor characteristics, and have electron emission properties. They can be used to manufacture various electronic components and devices. The ignition pole of the fuel pipe, the telecommunications equipment, the capacitor, the semiconductor admixture, the high-voltage high-frequency electricity and the plasma arc insulator, the radar transmission window, and the like.
7. Atomic energy industry and defense industry
Boron has a remarkable function of absorbing neutrons and can be used as a structural material for control rods and atomic reactors in atomic reactors.
Boron carbide has a high melting point, high compressive strength, radiation and chemical resistance, so it is an ideal protective material for aviation and armor. Certain compounds of boron are components for the manufacture of rocket nozzles, combustion chamber internals and jet engines. The hydride of boron is a commonly used combustion agent in liquid rocket propellants.
8. Agriculture
Boron is used in agriculture to produce boron fertilizers, insecticides, and the like.
This generation of biomass fuel Pellet Mill with big gearbox, with advantage as follow:
1-all gears flat connecting no taper gears, structure more properly than before,
2-and gears more bigger and tronger than before, roughly no need change the gears ,
3-the motor shaft and the machine main shaft directly connecting into the gearbox, so machine transmission efficiency is more higher than before.
