2、 Introduction to aramid fiber

The outstanding properties of aramid fiber are its high strength, high modulus, and excellent heat resistance. At the same time, it also has appropriate toughness for textile processing. The weight to tensile strength of standard PPTA aramid is 6 times that of steel wire, 3 times that of fiberglass, and 2 times that of high-strength nylon industrial yarn; Its tensile modulus is 3 times that of steel wire, 2 times that of fiberglass, and 10 times that of high-strength nylon industrial yarn; After 100 hours at 200 ℃, it can still maintain 75% of its original strength, and after 500 hours at 160 ℃, it can still maintain 95% of its original strength. Accordingly, para aramid is mostly used as a lightweight and heat-resistant textile structural material or composite structural reinforcement material. The disadvantages of the performance of para aramid include low compressive strength and modulus, poor resistance to moisture and ultraviolet radiation, and poor adhesion between the surface and substrate.

The main varieties of aramid fibers include aramid 1313 (meta aramid), aramid 1414 (para aramid, also known as aramid II), and aramid III (para heterocyclic aramid).
3、 The production process of aramid pulp

Aramid pulp is obtained by surface fibrillation treatment of aramid fibers, and its surface structure greatly improves the adhesion, making it very suitable as a reinforcing fiber for friction and sealing products.
Aramid pulp fibers are widely used in industrial papermaking due to their excellent wet processing and reinforcement properties. Pulp is easily dispersed in water for papermaking, and the high aspect ratio of pulp fibers provides the strength of aramid pulp. In addition to improving the tensile strength, modulus, and creep resistance of the elastic matrix, it is suitable for use as insulation paper and printed integrated circuit boards that require dimensional stability due to its low coefficient of thermal expansion, light weight, and excellent electrical properties. The lightweight and high-density components of aramid pulp can be used in electronic products such as communication lines and high-speed transmission circuits.

4、 Production process of aramid fiber precipitation

Settling fibers are formed by the contact of aramid raw material with DMAC/water mixture to form flocculent settling fibers, with a ratio of generally 1:20; The GLC2000 series dual inlet mixing and dispersing machine is used for dispersion. The GLC2000 series powder and liquid dispersing and mixing machine adopts dual inlet feeding. The aramid raw liquid and DMAC/water mixture enter the working chamber from two different feeding ports at the same time, and then mix and disperse. After discharge, the fibers settle, and the effect is good and the efficiency is high.

5、 Principle of sedimentation fiber mixing and dispersing machine equipment
The sedimentation fiber high-speed mixing and dispersing machine uses the high-speed rotation of a special rotor to generate a vacuum, which evenly sucks the powder into the hopper or working chamber and distributes it evenly in the rapidly flowing liquid flow. In the liquid flow, the powder is instantly wetted without producing agglomerated blocks. Due to the uniform wetting of the powder by the liquid flow from the beginning, there is no un wetted powder, nor will there be any crust formation on the surface of the liquid flow, stirring shaft, and container wall. Traditional craftsmanship is prone to forming hard crusts. It can be seen that using the GLC system can greatly improve the quality of products. The main reason for the reduction of dust is that the vacuum is generated by the liquid flow, and all the powder is introduced into the liquid flow without any residue. The environmentally friendly auxiliary facilities necessary for traditional processing techniques will no longer be needed here.
