PROCESS TO MANUFACTURE A MIXTURE OF P-ARAMID PULP WITH CHOPPED FIBERS, MIXTURE AND ITS USE |
| 摘要 |
A process to manufacture a mixture of p-aramid pulp with chopped fibers, wherein the process includes: providing a first mass that includes p-aramid pulp, providing a second mass that includes chopped fibers, guiding the first mass and the second mass into a mixing device, wherein the first mass and the second mass are mixed to yield a mixed mass, guiding the mixed mass on a dewatering device, whereupon the mixed mass is dewatered to yield a dewatered cake, guiding the dewatered cake, either directly or via a passage, through a cake breaker into a drying atmosphere to yield a dried intermediate, and guiding the dried intermediate, either directly or via a passage, through a homogenizing device into an opening device, wherein the dried intermediate is opened to arrive at an opened mixture of p-aramid pulp and chopped fibers. The mixture and its use are also described. |

1. A process to manufacture a mixture of p-aramid pulp with chopped fibers, wherein the process comprises:
a) providing a suspension comprising p-aramid pulp in water, b) providing a suspension comprising chopped fibers in water, wherein the chopped fibers comprise p-aramid or carbon, c) guiding the suspension from a) and the suspension from b) into a mixing device, wherein the suspensions are mixed to yield a mixed mass having a solid content of p-aramid pulp and chopped fibers in the range of from 50 wt. % to 95 wt. % of p-aramid pulp and from 5 wt. % to 50 wt. % of chopped fibers, d) guiding the mixed mass on a dewatering device, whereupon the mixed mass is dewatered to yield a dewatered cake, e) guiding the dewatered cake either
i) directly, orii) via a passage through a cake breaker into a drying atmosphere to yield a dried intermediate, and f) guiding the dried intermediate either
i) directly, orii) via a passage through a homogenizing device into an opening device, wherein the dried intermediate is opened to arrive at an opened mixture of p-aramid pulp and chopped fibers. |
