Glass fiber material is a kind of inorganic non-metallic material with excellent performance. It has high tensile strength, high elastic modulus, good rigidity, low elongation, good contact with resin, insulation and heat insulation, corrosion resistance and waterproof, strong filterability, The advantages of low water absorption and good processability. It can be made into products of different forms such as strands, bundles, felts and woven fabrics. It is the base material of structural materials and functional materials that are indispensable for the development of high-tech industries.
1. The influence of the position of the oiler on the drawing tension and hairiness
The oil applicator is an equipment device that uniformly coats the glass fiber sizing agent on the surface of the glass fiber precursor. In order to study the influence of the position of the oil applicator on the drawing tension and hairiness of D450, the distance between the oil applicator and the center of the leakage plate was adjusted to A and B respectively in the experiment. Under the conditions of these two oil applicator positions, D450 was measured. The drawing tension and hairiness of D450 have no obvious changes; the position of the surface oiler has little effect on the drawing tension and hairiness of D450.
2. The influence of the type of bundling device on drawing tension and hairiness
The bundling device is a device for bundling a plurality of glass fiber strands into a bundle. Commonly used bunching devices are bunchers and graphite rods. In order to study the effect of different bundling devices on the drawing tension and hairiness of D450, two devices were used in the experiment. The results showed that the drawing tension using the bundling device was about 10% higher than the drawing tension using the graphite rod. The production quantity difference was not big, but the bundling The bundling performance of the concentrator is better, therefore, the concentrator should be given priority in production.
3. The influence of the shape of the wire arranging device on the drawing tension and hairiness
In order to study the influence of the wire arranging device shape on the drawing tension and hairiness, the original wire arranging device shape was adjusted, reducing the wire diameter of the arranging wire and reducing the length and short angle distance, and comparing the D450 produced before and after the shape of the arranging device was changed. The results show that the wire drawing tension of the arranging device is appropriately reduced after adjustment, and the number of hairiness is not significantly reduced; if the diameter of the fiber produced is smaller than D450, the number of hairiness after adjustment of the arranging device is significantly reduced, so it is more important to use the adjusted arranging device. reasonable.
4. The influence of drawing machine distance on drawing tension and hairiness
The distance of the wire drawing machine is the horizontal distance between the center of the wire drawing machine head and the center of the slip plate. In the experiment, there are three types of wire drawing distances: A, B, and C, where A>B>C. It is found by checking the fiber tension and hairiness obtained under the three wire drawing distances. Experiments have shown that as the drawing distance decreases, the tow angle decreases, and the drawing tension also decreases. However, too small drawing tension is not conducive to the wiring. In order to ensure the normal wiring, it is necessary to increase the horizontal movement distance of the wiring To increase the drawing tension.
