Ultrafine Ultra High Molecular Weight Polyethylene Continuous production equipment

Product Details

1. Manufacturing process of flexible UD cloth

Flexible UD cloth: fiber + modified polystyrene resin (modified polyethylene resin is made of polystyrene resin modified by ethylene vinyl acetate copolymer EVA with high flexibility, elasticity and filler compatibility)

PE UD: Using ultra-high molecular weight polyethylene fiber as raw material, using specially formulated matrix material and 2 to 12 unidirectionally arranged fiber flakes in a 90° orthogonal manner, through specific process technology and resin matrix composite processing, Its appearance is white fibrous flakes.

Aramid UD: Aramid fiber has high strength, high elastic modulus, and its strength is more than 8 times that of steel at the same weight. Due to its unique properties, this fiber is currently one of the best bulletproof materials in the world. .

The aramid fiber material produced is based on our special UD technology, where the fibers are arranged in parallel in each layer, each layer is shaped by a resin matrix.

2. The production process of hard UD cloth

Hard UD cloth: fiber + water-based polyurethane glue (impregnated glue)

Using ultra-high molecular weight polyethylene fiber as raw material, using special water-based dispersion binder, two fiber layers arranged individually at 0°/90° are compounded by specific technology, and their appearance is white fiber flakes .

Mainly used for bulletproof inserts, bulletproof armor, bulletproof shields, bulletproof walls and other hard bulletproof applications; light weight, with excellent protection effect for multi-bullet shooting and oblique shooting.

Excellent anti-frag performance, which can greatly reduce sag. At the same time, due to the extremely low dielectric properties of PE fiber, PE fiber can play a better invisible effect when using PE fiber as the protective shell of important devices such as warships, tanks or turrets.

3. Continuous production line of film-free release paper UD cloth process

Invention patent: 2017101291563

Use and Features

1. This machine is suitable for the continuous production of UD non-woven fabrics such as bulletproof vests, helmets, shields, chest inserts, armored vehicles, and explosion-proof blankets for military protective equipment.

2. Drying by circulating air heating system.

3. Using computer PLC control system, easy to operate, high production efficiency and less labor.

4. The mirror roller pulls the wire and lays the wire to ensure that the fiber's own performance is not damaged.

5. Use release paper instead of film to complete the entire production process, and finally release the release paper to form a film-free UD cloth.

5. Influencing factors of ballistic performance of UHMWPE fiber composites

Influencing factors: modulus, content of matrix resin, fiber fabric structure, composite surface density, etc.

The application of UHMWPE fiber in the field of safety protection products embodies the excellent performance of UHMWPE fiber. The impact toughness of UHMWPE fiber composite material is very good, and its specific impact absorption energy is higher than that of composite materials. Its specific impact absorption energy is aramid fiber and carbon fiber respectively. and 2.6, 3 and 1.8 times that of E glass fiber composites. Because of its good impact resistance and ballistic resistance, it is suitable for body armor, helmets and bulletproof armor. The ballistic resistance of UHMWPE fiber composite armor is 2.5 times higher than that of aramid fiber armor structure, and it can be made into a strong and light armor structure. It is more than twice the fiber and has been widely used to make flexible body armor and bulletproof steel plate materials.

6. About UHMWPE fiber cloth

In addition to being used in bulletproof vests and bulletproof helmets, UHMWPE fiber can also be used to make bulletproof armor by its light weight, which can be used for cash transport vehicles, armored vehicles, bulletproof vehicles, and light armed helicopters to reduce weight; it can also be used to make Explosion-proof lining of the box. Because UHMWPE fiber has good textile processing properties, it can also be made into various stab-resistant and cut-resistant fabrics.

When impacted by a bullet, the high-performance fiber material will be stretched and sheared by the projectile, and the impact force will be diffused to areas other than the impact point by generating elastic deformation, thereby effectively consuming the energy of the bullet, thereby resisting the bullet or reducing the impact of the bullet. Human injury. However, the defense level of soft body armor is really not high. At present, the soft body armor on the market only has grades IIA, II and IIIA, which can usually only be used to resist the attacks of pistols and shotgun bullets. If you are dealing with higher-level threats, you will need to equip hard body armor.
