Description
Technical Field
The invention relates to the field of power cable steam crosslinking, in particular to an operation method of a steam oven for power cable steam crosslinking.
Background
At present, a steam crosslinking furnace is mainly used for silane crosslinking, plastic particles are converted into a molten state from particles in a screw of an extruding machine through heating of each region in the extruding process, and are extruded out of a conductor or a cable core through a machine head to form an insulation or a sheath, as a macromolecular material has dependence on temperature, the macromolecular material expands with the increase of temperature, the inter-molecular distance is increased, and the molecular energy is increased, so that the state of internal molecules of the plastic is changed in the extruding process, the original glass state is converted into a high-elastic state, and finally the plastic is converted into a viscous state, the viscous state macromolecule reaches the maximum energy of the linear macromolecule, and the internal molecules cannot be recovered, if the high elasticity, the limit elongation and the creep property and the strength of the molecules are required to be continuously increased, the linear macromolecule is required to be converted into a bulk macromolecule, the molecules are more stable and are not easy to deform, and the molecular energy is required to be increased when the linear macromolecule is converted into the bulk macromolecule, namely the plastic is heated, so that the molecular chain is crosslinked; if the temperature of the plastic is too high in a local single time through the screw, the plastic can be coked, so that the plastic needs to be externally heated for a long time, namely, the plastic is steamed.
The conventional enterprises generally adopt a water pit stewing method to crosslink plastics, the whole coiled wire is generally required to be put into water for stewing for more than one hour, the efficiency is low, the materials are extremely wasted, in addition, in the stewing process, the cable is prevented from entering water, the cable is required to be sealed and the sealing performance is particularly good, and the operation is more complicated; because the temperature of the water vapor is higher than that of the hot water, a later-stage enterprise reforms a cooking sump, water is arranged below the water sump, and a cable is put above the water sump, so that the efficiency of the method is improved compared with that of a earlier-stage cooking method, but the sump has poor sealing property, so that a large amount of water vapor is easily leaked, material waste is caused, the efficiency is reduced, and therefore, the problems that how to crosslink plastic cooking reduces material consumption and the cooking efficiency is increased are the most considered at present.
Enterprises generally adopt warm water for crosslinking, the reels are required to be fully placed in water and steamed, and the cables cannot be fed water absolutely due to the uniqueness of the cables, otherwise, the magnetic fields around the cables can be directly influenced to reduce the service life of the cables, so that the ends of the cables are required to be sealed absolutely during conventional steaming; because the water in the cooking pool is used for a long time, the surface of the cable is dirty after the cable is cooked, and the water is required to be dried for a long time, so that the surface impurities are erased; the temperature of boiling water can only reach the maximum degree, the heat preservation effect is not ideal, long-time heating is required to fully achieve crosslinking, so that resource waste is caused, water is required to be changed frequently in a warm water crosslinking pool, otherwise, the surface of a cable is polluted, even impurities damage the surface of the cable, and the waste of water resource is caused; due to the limitation of the warm water crosslinking pool, the process of putting into the pool and taking out from the pool is inconvenient, even the surface of the cable is damaged, the whole cable is scrapped, and the problem of how to reduce the material consumption and increase the cooking efficiency of the existing steam crosslinking furnace in the process of cooking and crosslinking plastics is a long-term difficult technical problem; for the above reasons, a method of operating a steam oven for steam crosslinking of power cables has been developed.
