Description
Technical Field
The invention relates to the field of glass fiber manufacturing equipment, in particular to a glass fiber drawing machine capable of reducing moisture of yarn groups and a using method thereof.
Background
Glass fibers are commonly used as reinforcing materials in composite materials, electrical and thermal insulation materials, circuit substrates, and other various fields of the national economy. China is a large glass fiber producing country, a plurality of glass fiber manufacturers are in China, market competition is strong, and the key for improving product quality and product grade and additional value by improving process technology and production equipment is the benefit improvement of the manufacturers.
The glass fiber is a basic reinforcing material, and with the continuous development and progress of science and technology, the application field of the glass fiber is wider and wider, and the glass fiber is subdivided. The downstream requirements make glass fiber manufacturers continuously develop new products, and the requirements of high-end application customers on the stability and consistency of product quality are higher and higher.
The glass fiber is used as a reinforcing material, has low cost, high modulus and higher cost performance. However, glass products are brittle and easy to break, and in order to protect glass fibers, increase the flexibility and the wear resistance of the glass products and be beneficial to being combined with a reinforced matrix during application, an organic wetting agent needs to be coated on the surfaces of the glass fibers during the fiber drawing process. The impregnating compound is generally aqueous emulsion or aqueous solution, the organic part of the impregnating compound needs to be dried at a certain high temperature to form a film, the impregnating compound can migrate from the inner layer to the outer layer of the bobbin along with the evaporation of water in the drying process, and the higher the water content is, the more serious the impregnating compound migrates.
The direct roving of the glass fiber is a large class of glass fiber, and is directly oriented to customers without subsequent processing after drawing, forming and drying, so that certain process defects cannot be compensated and balanced after the drawing and forming process is finished. It is known that sufficient moisture must be applied to glass fibers during drawing, and the negative effect caused by excessive moisture is that in the drying and dewatering process, organic components of the sizing agent can migrate from the center of a bobbin to the surface layer along with the moisture, so that the content of the surface layer is far higher than that of the central layer, and the parts with higher content of the sizing agent are slow in speed or even cannot be completely combined with a composite material matrix. Although the part with higher impregnating compound content can be removed by removing the skin, the positions of two end surfaces cannot be removed due to the characteristics of the forming process of the direct yarn, so that the continuous consistency of the product is influenced. If the moisture application amount in the glass fiber drawing process is reduced, the cooling effect of glass and the lubricity of moisture on yarns can be reduced, and the yarns with high temperature and low moisture are easy to cause the problems of poor bundling property, abrasive breakage, more broken filaments and the like in production, thereby seriously affecting the product quality.
Chinese patent CN112408780A discloses a single-side automatic reversing continuous on-line glass fiber chopping machine, which is the same as the wire drawing operation mode of the structure of the present application. However, the product produced by the method is chopped granular glass fiber, is different from the whole roll product related to the application, and does not have the problem of impregnating compound migration in the subsequent drying process.
Chinese patent CN210320840U discloses a drying device for yarn spinning, which is provided with a hot air blower and can dry and remove moisture from the output yarn. The yarn is dried in this patent by completely drying the yarn before it is wound into a package. Because of the brittle nature of glass fiber yarn, the glass fiber removes moisture before the coiling and can cause lubricated not enough and the mill-off in the winding process, and the equipment is more with the yarn contact point and the mill-off fibre easily, so this equipment is not suitable for glass fiber production.
The research direction of the application is as follows: not only is enough moisture application amount ensured to be used for cooling and lubricating the glass fiber, but also the moisture migration of the impregnating compound along with the moisture from inside to outside in the drying process is reduced, and a step of dewatering is required after winding and forming and before drying.
