METHOD FOR SEPARATING FIBERS

The invention relates to a method for separating fibers using a container with a specified receiving volume， a vacuum pump which is connected to the container volume via a vacuum line and a valve， and a ventilation line with a specified cross-sectional opening and at least one valve. The valve can be switched from a closed state into an open state in a time domain of 19 ms to 41 ms and from the open state into the closed state in a time domain of 20 ms to 45 ms. The method at least has the steps of filling the container with a specified quantity of water and at least one fiber composite， closing the container in a gas-tight manner， mixing the water and the fiber composite using mechanical energy， in particular by stirring， generating kinetic energy in the fiber composite by lowering the container internal pressure to a value between -700 hPa to -950 hPa， and equalizing the pressure in the container interior in order to generate cavitation in the fiber composite. The pressure equalization in the container interior for generating cavitation in the fiber composite takes place within at least one time domain of 0.001 s and 1 s.

本发明涉及一种利用容器(container)分离纤维的方法，该容器具备指定的容纳容积；该系统包含通过真空管路(vacuum line)和阀门(valve)与容器内部容积相连的真空泵(vacuum pump)，以及带有指定通径(cross-sectional opening)和至少一个阀门的通气管路(ventilation line)。该阀门可在19ms至41ms的时域内从关闭状态切换至开启状态，并可在20ms至45ms的时域内从开启状态切换回关闭状态。该方法至少包含以下步骤：向容器内注入指定量的水与至少一种纤维复合材料(fiber composite)；以气密(gas-tight)方式封闭容器；通过机械能，尤其是通过搅拌(stirring)操作，使水与纤维复合材料混合均匀；将容器内部压力降至-700hPa至-950hPa之间，以使纤维复合材料获得动能；以及均衡容器内部压力，以在纤维复合材料中引发空化现象(cavitation)。用于在纤维复合材料中产生空化现象的容器内部压力均衡过程，需至少在0.001s至1s的时域内完成。
