If electric heating is used, the wiring is required to be firm and reliable and the wire is prevented from overheating. Other electrical equipment should be strictly maintained to keep it in good condition. Cold working is a production process for processing methods such as stamping, extrusion or chip processing of raw materials or blanks. It occupies a large proportion in the packaging machinery manufacturing industry. There are many types of cold-processing equipment, such as car, drill, boring, milling, planing, inserting, pulling, grinding, etc., as well as precision machine tools, CNC machine tools, and special-purpose EDM, ultrasonic and laser processing machines. Many types. In metal chip processing, a large amount of flammable liquid such as lubricating oil or hydraulic oil is often used, and high temperature and sparks are generated during the processing. Therefore, although it belongs to the production of apes, the fire prevention work cannot be ignored. In particular, EDM machines, CNC and combined machine tools, precision machine tools and lifting vehicles, which have typical fire safety requirements, are strictly regulated in the electronic control operating system, auxiliary equipment systems, equipment maintenance and repair, and site cleaning. Effective implementation. Large-scale cold-worked workshops shall be first- and second-class fire-resistant buildings. Other simple buildings shall not be built in the workshop. The use and management of flammable and combustible materials shall be tightened by fire and electricity.
Heat treatment is a processing technique that improves the properties of metal materials and their products. There are usually annealing, normalizing, quenching, tempering and chemical heat treatment projects, among which oil bath quenching, salt bath quenching, and chemical heat treatment are more dangerous. When the oil bath is quenched, the flammable liquid such as engine oil or transformer oil is often used as the cooling medium, and the metal workpiece needs to be heated to the hot state, so the fire prevention is particularly important. The quenching train is required to be installed in the first and second-class refractory buildings, and maintain a certain fire separation distance with other workshops and dangerous goods warehouses. When quenching, the oil temperature should be strictly controlled, and the flash point should not be exceeded. The filling factor of the oil tank should not exceed 0.75; the oil should be updated in time to prevent oxidation and deterioration, and the flash point drops. When the salt bath is quenched, the molten salt due to high temperature will not only ignite when exposed to organic matter, but also explode when exposed to moisture due to rapid expansion of volume. Therefore, salt baths are more dangerous than oil bath quenching. Therefore, the salt should not be too fast when heating up, so that the water content is fully evaporated; the salt and salt baths are required to be free of impurities. At high temperatures, it is strictly forbidden to add salt to the bath; the building construction requires fire prevention and no leakage of rain and snow. . (Finish)
Fischer-Tropsch wax can be used in plastic processing, such as injection molding, extrusion and pelletizing industries. In the production process of masterbatch and modified plastics, Fischer-Tropsch wax contributes to the dispersion of fillers and excellent smoothness during mixing. It can be used as an external lubricant for PVC. The low viscosity can increase the production speed of the product. It helps to disperse the pigments and fillers during mixing. It is especially useful in the extrusion of high-viscosity systems. It is more than ordinary PE WAX. 40-50% less, and can significantly improve the surface gloss of the product. When using intense colors, the melted Fischer-Tropsch wax can effectively wet the dye and reduce the extrusion viscosity.
When used in the ink as a particulate powder, it can improve the wear resistance and wrinkle resistance of the applied material. When applied to the coating, it can have a wrinkling effect, and when used in a micro powder state, it can form a wrinkle effect of stripes and water lines. When powder coating resin is added, it plays a role of lubrication in the extrusion process, which can reduce screw torque, reduce energy consumption and improve production efficiency.
