Aramid precipitation equipment and process

Aramid precipitation fibers are flocculent fibers generated by contacting aramid raw liquid with coagulation liquid (such as DMAC/water mixture), which require specialized equipment to achieve efficient dispersion and molding:

1. ‌Device Type‌：

• ‌Continuous shear settling machineXLC2000Adopting a dual inlet design, the aramid raw material and coagulation liquid are injected simultaneously, and uniform precipitated fibers are formed through high-speed shearing

• ‌High speed disperser (such as Sijun GRS2000)Equipped with automatic control function, suitable for the preparation of aramid 1414 fiber, capable of handling high viscosity materials and optimizing fiber aspect ratio
  .

2. ‌Key process points‌：

• ‌mixing ratioThe ratio of aramid raw liquid to coagulation liquid is usually 1:20, which needs to be precisely controlled to ensure fiber morphology
  .

• ‌Decentralized technologyFor example, the GLC2000 series equipment achieves rapid mixing of raw liquid and coagulation liquid through strong shear force, improving sedimentation efficiency

2、 Fusite precipitated fiber

Fusite precipitated fiber is a thin film fiber material of aromatic meta polyamide. Fusite precipitated fibers have excellent thermal stability (can be used for more than 10 years at 220 ℃, heated for 1000 hours at 240 ℃, with mechanical strength still maintaining 65% of its original level, and only decompose into a small amount of gas at 370 ℃ or above), flame retardancy (self extinguishing, surface carbonization during high-temperature combustion, non combustible, and no molten droplets), electrical insulation (aramid insulation paper can withstand a breakdown voltage of up to 10kV/mm), chemical stability, adhesion, and thermal bonding properties. They are widely used in the manufacturing of electrical insulation paper, high-temperature filter materials, packaging, honeycomb structure materials, and are important basic materials in high-tech fields such as aerospace, aviation, * * *, electronics, communication, environmental protection, petroleum, chemical, and marine development.
Main technical indicators: characteristic viscosity ≥ 1.6, absolute dryness rate ≤ 14%, original beating degree (30-50) oSR, 240 ℃ thermal shrinkage rate ≤ 20%.

3、 Preparation process of meta aramid precipitation fiber

The characteristic of meta aramid precipitated fibers is a water containing flocculent state. The XLC2000 is equipped with a specially designed screw rotor, mixing head, dispersing head, with one inlet for the coagulation bath and the other for the aramid solution. The working principle is to use the high-speed rotation of a special screw rotor to generate feed, and continuously and uniformly introduce the high modulus liquid crystal raw material into the rapidly flowing DMAC and water mixture. After the mixing reaction in the shear chamber, it is instantly sheared and dispersed, precipitating down like short fibers. Since the mixed liquid and the raw material are not in contact with each other before mixing, only at the moment before mixing, the raw material is dispersed and introduced into the mixed liquid, so the precipitated fibers are finer and more uniform. The Xide mechanical settling machine adopts an upright design, consisting of 1-3 working chambers. Under the high-speed drive of the motor, the material moves at high speed in the narrow gap between the rotor and stator, forming turbulent flow. The material is subjected to stronger hydraulic shear, centrifugal extrusion, high-speed cutting, impact, and grinding, achieving the effects of dispersion, emulsification, and fragmentation. The distribution range of material particle size and the effect of homogenization and refinement, as well as the output size, are determined by the physical properties of the processed material, the number of working chambers, and the control of the time the material stays in the working chamber.

4、 Advantages of Taicang Xide precipitation mechanism preparation

When production requires a continuous process, we recommend the XLC2000 series continuous aramid fiber settling machine to meet the requirements. The original liquid and mixed liquid are instantly mixed and dispersed, and XLC effectively combines this mixing and dispersion to form a homogenized product. The various substances mixed are mixed in a certain proportion, then dispersed and sheared to directly obtain the finished product. You can eliminate the need for tanks and other auxiliary equipment, which saves costs and operational expenses. During the production process, XLC has great flexibility and also allows for higher material density.
