Embodiment Construction
[0016] A kind of assay method of centrifugal method glass microfiber strength of the present invention, comprises the following steps:
[0017] (1) Take by weighing the 2-6 μm glass microfiber sample 1g that will be detected by centrifugal method;
[0018] (2) Put the weighed glass microfiber sample into the juice extractor, and add 600ml of 20°C distilled water, then press the electric switch to start beating;
[0019] (3) Press the stop switch after beating for 5 seconds;
[0020] (4) Remove the conditioning cup of the juicer, pour the glass microfiber slurry in the cup into the indicating measuring cylinder, and use a small amount of water to rinse the conditioning cup several times (50-100ml each time, 4-8 times). Pour the liquid into the measuring cylinder until the scale of the measuring cylinder is 1000ml;
[0021] (5) Stand still for 5 minutes, observe the scale corresponding to the layered position of the fiber in the graduated cylinder, and the scale value is the f...

Abstract
The invention discloses a method for measuring strength of glass microfiber with a centrifugation process. The method comprises steps as follows: firstly, a standard mass of to-be-detected glass microfiber samples prepared with the centrifugation process are weighed; the weighed glass microfiber samples are put in a pulping device, a standard volume of water is added, and the pulping device is started and continuously operates for a standard pulping time; secondarily, pulp in the operated pulping device is completely poured into a measuring cylinder, and water is added to the measuring cylinder to the preset standard scale; finally, the pulp in the measuring cylinder is left to stand for a standard standing time, the corresponding scale of the fiber in the layering position of the measuring cylinder is observed immediately, and the scale value indicates the strength of the microfiber. By means of the method, the strength of the glass microfiber prepared with the centrifuge process can be quantified. By means of the measuring method, disturbance of human factors to measurement is eliminated, production can be timely and accurately guided, middle transition products and unqualified products are reduced, the production efficiency is improved, and the cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of glass fiber detection, in particular to a method for measuring the strength of glass microfibers by centrifugal method. Background technique [0002] In recent years, due to the extensive use of glass microfibers, the development and maturity of centrifugal glass microfiber technology has been promoted. In the past, the production of glass microfibers was all produced by the flame blowing method, and the fibers produced were mainly used in papermaking (AGM separators), so the measurement of fiber properties was designed around papermaking. With the maturity of centrifugation technology , the use of glass microfibers is also constantly expanding; and the properties of centrifugal fibers and flame fibers are also somewhat different, and the scope of application is also different, but the strength of the fibers is a very key indicator, in the application of microfibers. of equal importance. The strength of...
