A new generation of wood bulletproof ceramics can be made from hemp stalk core powder, which has high protective ability and light weight. Hemp electromagnetic shielding plate can be used to shield electronic information of command post; The high-efficiency carbon adsorption material made of hemp stalk can be used to make high-grade gas masks; Hemp seed protein can be extracted from the residue of hemp seed oil pressing, which can be used to make high nutritional value combat rations. Hemp seed biodiesel has been tested by millions of kilometers of tank engines and ground vehicles.
Extended data
trait
1, hemp fiber is the softest of all kinds of fibers, and its fineness is only one third of that of ramie, which is equivalent to that of cotton fiber. The top of the fiber is blunt and round, and there is no sharp top like ramie and flax, so the finished product is particularly soft and fit.
2. There are many cracks and small holes in the center of hemp fiber and the surface of the fiber, which form excellent capillary effect, so it is good for perspiration and moisture absorption.
3. The cross-section of hemp fiber is more complex than ramie, flax, cotton and wool, and it is irregular triangle, hexagon, oblate circle, waist circle, etc. The hollow cavity and shape are different, and its molecular structure is polygonal, loose and spiral. Therefore, hemp fiber has a good dissipation effect on sound waves and light waves, and can block the radiation of strong ultraviolet light without special finishing.
4. Avoid static electricity accumulation. Hemp is a poor conductor, and its electric breakdown resistance is about 30%-90% higher than that of cotton fiber. It is a good insulating material. Because hemp fiber has excellent moisture absorption performance, hemp products exposed to the air generally contain about 12% of water, and the humidity in the air can reach 95%, and the water content can reach 30%, but the feel is not wet. Therefore, hemp products can be easily wetted.
5. Hemp fiber has high heat resistance, and can not change color at 370'C, which is suitable for all kinds of fabrics.
6. Anti-mildew and sterilization. Hemp fiber is hollow and usually contains oxygen, which makes anaerobic bacteria unable to survive. It has obvious killing effect on Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, Trichophyton gypseum, Penicillium, etc. Hemp does not need any chemical pesticides and pesticides, and it can prevent athlete's foot. It is a standard green product.
