The sizing agent is composed of coupling agent, lubricant, film-forming agent and other substances. In the production process of glass fiber, the sizing agent is mainly applied by devices made of graphite, ceramic, resin and other materials.

In addition, as for the quality of the finished glass fiber products, the moisture content of the existing glass fiber raw yarn is controlled at about 10%. For every 1 percentage point reduction in moisture, the stability of the sizing agent can be improved by about 10%.

[0036] The performance of the oil coating roller 1 obtained in Examples 1-3 and Comparative Examples 1-3 was tested, and the test results are as follows: ① The dispersion rate of the glass fiber bundle specifically refers to, taking a glass fiber bundle consisting of 100 glass fibers as an example, the proportion of glass fibers that are completely dispersed individually after being oiled by the oiling roller 1 to the total amount of glass fibers.

[0037] The wear resistance is based on GB / T1689-1998, and the wear amount is tested using an Akron abrasion tester.

[0038] The glass fiber bundles are dispersed by the dispersing and infiltrating device of the present application and the above-mentioned oil coating roller 1, wherein Examples 1-3 have a good dispersing effect on the glass fiber bundles. Examples 1-3 use powdered PEEK and powdered molybdenum disulfide to work synergistically to form a discontinuous soft and hard interlaced interface on the roller surface, which can disperse the glass fiber filaments to a higher degree.

[0039] In Comparative Examples 1-3, since no chlorinated paraffin was added, the roller surface was easily adhered to the wetting agent and dust, and the wetting effect was relatively poor.
