There are two main types of aviation fuels used by airlines around the world: aviation gasoline and jet fuel, which are suitable for different types of aircraft engines. Aviation gasoline is used as fuel for piston type aviation engines. Due to the fact that jet fuels commonly produced and widely used both domestically and internationally belong to the kerosene type, they are commonly referred to as aviation kerosene, abbreviated as aviation coal.
Diesel is a light petroleum product, a complex mixture of hydrocarbons (with a carbon atom number of about 10-22), used as fuel for diesel engines. It is mainly composed of diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced through shale oil processing and coal liquefaction, and can be divided into two categories: light diesel (with a boiling point range of about 180-370 â??) and heavy diesel (with a boiling point range of about 350-410 â??). Widely used in large vehicles, railway locomotives, and ships. The most important use of diesel is for diesel engines in vehicles and ships. Compared with gasoline engines, diesel engines have higher thermal efficiency and lower fuel consumption. Diesel has low energy consumption, so some small cars and even high-performance cars have switched to diesel.

Application of nitrocellulose Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.
1. Chopped basalt fiber Basalt fiber is a kind of inorganic fiber material. Chopped basalt fiber is an inorganic mineral fiber with a length of less than 50mm and can be evenly dispersed in cement concrete. 2. Characteristics of chopped basalt fibers (1) The naturalness of raw materials. Because the raw material for producing continuous basalt fiber depends on the natural volcanic extrusive rock, there are no ingredients harmful to human health except that it is inherently high in chemical stability and thermal stability. (2) Comprehensive performance. Basalt fiber is acid resistant and alkali resistant. It is both low temperature and high temperature resistant. It is insulated and insulated by heat and electricity. Its tensile strength is higher than that of large tow carbon fiber. Its elongation at break is even better than that of small tow carbon fibers. It has high compressive strength, shear strength and adaptability to aging, and has good comprehensive properties in harsh environment. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of steel fiber and polyester fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with asphalt concrete, cement concrete and mortar. The newly mixed basalt fiber concrete has stable volume, good workability and durability, and has superior high temperature resistance, anti-seepage, crack resistance and impact resistance.
1. Basalt short fiber - a new material to replace steel fiber. Basalt short fiber is an inorganic mineral fiber with a length of less than 50mm, which can be evenly dispersed in cement concrete. 2. Characteristics of basalt short fiber (1) the specific gravity of steel fiber is 7.8 and that of cement concrete is 2.5. After mixing, the specific gravity of steel fiber is higher than that of cement, and the cement will sink and have poor dispersion. The specific gravity of basalt short fiber is 2.6, which is basically equivalent to that of cement concrete. After mixing, it does not sink, has good dispersion, is degradable, and is green. The road surface will not be as hard as steel fiber, resulting in car driving noise.. (2) Basalt staple fiber is a real "multifunctional" fiber. Acid and alkali resistance (especially alkali resistance, fully applicable to cement concrete), low and high temperature resistance, insulation and sound insulation. The tensile strength is three times that of steel fiber. The corrosion resistance of basalt fiber is better than that of steel fiber. The compressive strength is 20% higher than that of steel fiber, which is suitable for harsh environment. It has excellent comprehensive performance. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of 50% steel fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with cement concrete and mortar. Fresh basalt fiber concrete has stable volume, good workability and durability, and has excellent high temperature resistance, impermeability, crack resistance and impact resistance.
