Nitrocellulose is a white, odorless, and odorless solid. Celluloid plastic is a thermoplastic material containing 20% camphor plasticizer. It softens significantly at 80 , can be molded and processed at 110-125, and can self ignite above 165 . Transparent, soft, with high mechanical strength and low water absorption. No deformation and no white spots in boiling water for 2 minutes. Stable to water and general dilute acid solutions, can be corroded by dilute alkaline solution, partially soluble in benzene and dichloroethylene, and soluble in solvents such as ethanol and ethyl acetate.
Method of production
Nitrocellulose is a mixture of acid that nitrates cellulose, undergoes acid removal, pre washing, boiling, washing, dehydration, and then uses alcohol to remove water, resulting in nitrocellulose containing alcohol.
purpose
Nitrocellulose is mainly used in the plastic industry to manufacture stationery and educational items such as table tennis balls, triangular plates, pen holders, eyeglass frames, toys, and umbrella handles and tool handles in daily necessities. Nitrocellulose can also be used as a fiber, adhesive, coating, and substrate material.
Security
This product is non-toxic. This product belongs to Class A flammable dangerous goods. Packaged in wooden boxes with plastic bags lined inside. Each box should not exceed 160kg, or packaged according to user requirements. There should be a "flammable" mark on the outside of the box. Storage should be placed in a dry, ventilated, and clean warehouse, away from heat sources and direct sunlight. It should not be stored together with acidic, self igniting, and explosive materials. It is strictly prohibited to approach open flames. Transportation should be protected from sunlight and rain, and should be carried out in accordance with the transportation regulations of the transportation department for dangerous goods.
Forming processing
CN is fully kneaded with plasticizers (such as camphor), solvents (alcohol), dyes (or pigments) in a kneading machine at 36, and then filtered in a pressure filter at 60 . The filtered material is rolled on a two roller rolling machine, and the resulting thin sheet is crushed, dried, flattened, or polished to obtain sheet-like CN plastic. The rolled thin sheet can also be placed into an extrusion machine to form a tubular object.
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.
