Product Description
Prepare raw materials
At present, the preparation methods of raw materials at home and abroad are different, the solvents used are different, and the solid content is also different. Therefore, there is no fixed unified mode, and the production equipment varies greatly, while conventional melt spinning does not add solvent. But no matter which method is adopted, the desired effect can be achieved in the end. Because the production is continuous, the ratio of raw materials cannot fluctuate, and it is required to be uniform throughout. Although the increase in solid content is one of the important means to increase production, the draw ratio is also increased, and the overall vehicle speed must respond faster, which increases the difficulty of operation. However, if you can control the percentage of solid content within an appropriate concentration, it is still possible, and you should do what you can according to your own situation. Increasing the speed of the metering pump is also one of the effective means to increase production.
mixing material
The screw extruder plays the role of conveying-stirring-heating-pressurizing on the material. First of all, the slurry before entering the “screw” must be defoamed and must not contain water vapor, and the material must be fully kneaded and stirred during the transportation process. The heating temperature of each zone should be set according to the position of the kneading block on the screw, and a certain conveying pressure should be guaranteed. The setting of the screw kneading block is very theoretical, and different combinations will have different effects on the mixing of materials.
spinning
The function of the spinning box is mainly to keep warm; to control temperature; to evenly distribute the material to each spinning assembly.
spinning
The material is extruded into filaments by the metering pump, which is realized through the spinneret. The hole diameter of the plate and the shape of the plane are its important technical parameters, which play a role in the forming and tensile properties of the fiber. Crucial role. The temperature at the spinning box and the spinneret is matched, and the temperature parameter is set by observing the molten state of the extruded filament. But in order to control precisely, also need to have some specific technical conditions and practical experience.
extraction
It is mainly to extract and replace a large amount of solvent in the filaments, so as to obtain “pure” high-strength polyethylene fibers. The selection of extractant varies from manufacturer to manufacturer, and the production process is also different. So far, it is difficult to find an ideal extractant that is economical, practical, safe and environmentally friendly, has good extraction effect, and is non-toxic and tasteless [internationally, it is also a problem that cannot be solved for a long time].
In the process from spinning to extraction, the silk strands are stretched randomly and continuously. From the appearance, it changes from thick to thin, from translucent to semi-milky white. The stretchability of the silk also gradually increases, with a little “strength “. If viewed from the inside of the silk, the molecular structure of the raw material has not changed greatly, the macromolecules are not aligned, and they are still in a disordered state. The molecules are wrapped and isolated by a large number of solvents, and cannot form molecular chains. If the chain cannot be formed, the silk cannot have real strength. At this time, the inside of the fiber is actually like a circular tube-shaped network. The molecular particles of polyethylene are in the tube network. As the fiber continues to stretch and become thinner, the solvent is continuously precipitated, and the shape of the tube network From round to long, from comb to dense, the density between material molecules gradually increases, and the arrangement of macromolecules also gradually changes from a disordered state to a partially ordered state.
dry
The main purpose of the drying process is to remove and dry the extractant sticking to the filaments for drawing purposes. This process seems simple to control, but it is actually quite difficult. If the temperature and tension of the process are not properly controlled, a large number of parallel and stiff threads will occur, resulting in the inability to continue processing the semi-finished tow. The grasp of drying temperature and drying length is the key. This process should not be underestimated, it is directly related to the product quality of post-drawing.
heating draft
The drafting process of ultra-high molecular weight polyethylene fibers is basically the same as that of conventional polyester staple fibers in terms of form, but the required control accuracy is quite different. The fiber must be drawn in multiple stages in order to achieve the characteristics of high strength and high modulus. During each stage of underdrawing, the intermolecular structure changes greatly. With the stretching, the macromolecules are arranged from disordered state to ordered state, and the crystallinity gradually increases. Only when the orientation degree of the macromolecules of the fiber along the fiber axis increases, the number of macromolecular chains will increase, the cohesion force will be greater, and the strength of the fiber will naturally be higher. The crystallinity of the fiber increases, and the initial modulus also naturally increases. Under the action of external force, the fiber has smaller elongation and smaller deformation.
During the process of fiber understretching, the understretch ratio should be as large as possible, and the fiber should have a sudden stretch change, so as to promote the orderly orientation and high crystallization of macromolecules. The internal crystallization of the fiber undergoes crystallization transformation at the same time as the high degree of orientation is formed. Due to the high molecular weight of this kind of fiber and its strong resistance to external forces, it can only be produced by thermal stretching process. Therefore, a higher stretching temperature is required to achieve high drafting. The temperature of each stage of stretching is different. It depends on the state of the filament in the previous process. There is no fixed number, but it must be within the temperature range that the fiber itself can bear. In production, the temperature generally does not exceed 155 degrees Celsius. Otherwise, there will be hard threads and stiff threads.
Winding
Requirements for coil forming: the coil has no slump or burr, and the tow must be fixed in length and weight. The so-called fixed length and fixed weight are by no means simple. The requirements for the length and weight of tow have deep connotations, and it is very difficult to grasp them accurately. It is a requirement that all production processes must be normal and stable, and the fineness of the fiber can only be guaranteed if it is always uniform. Whoever can truly achieve the technical level of fixed length and fixed weight will reach the peak in the field of high-strength fibers.
