Description
Technical Field
The invention belongs to the technical field of rubber product vulcanizing devices, and particularly relates to a coupled semi-annular bending waveguide microwave reactor.
Background
Rubber raw rubber also has some useful application characteristics, but has a plurality of defects, such as low strength and low elasticity; it becomes hard when cold and sticky when hot; easily aged, etc. To improve the properties of the raw rubber, sulfur or many other chemical crosslinking agents and physicochemical methods are used for crosslinking, thereby expanding the range of applications of the rubber. In the rubber industry, it has been customary to refer to cross-linking of rubber as vulcanization. The vulcanization lays a foundation for large-scale industrial production and application of rubber.
After latex is obtained from a rubber tree, the latex is subjected to impurity removal, dilution and acid addition for solidification, and industrial natural rubber finished products are obtained through curing, pressing and creping, granulation and vulcanization. In the process, the rubber is subjected to a series of complex chemical changes, and the plastic rubber compound is changed into high-elasticity or hard cross-linked rubber, so that more complete physical and mechanical properties and chemical properties are obtained, and the use value and the application range of the rubber material are improved and widened. Thus, vulcanization is of great importance for the manufacture and use of rubber and its articles.
Vulcanization can be achieved by: the semi-finished product made by processing raw rubber, plasticated rubber and mixed rubber through calendering, extruding, forming and the like is converted into a soft elastic rubber product or a hard rubber product again under the action of a vulcanization system under certain external conditions, so that the technical process of service performance is obtained. In the vulcanization process, raw rubber in the rubber material components and a vulcanizing agent or raw rubber are heated to generate chemical reaction, and linear rubber macromolecules are crosslinked into macromolecules with a three-dimensional network structure.
The vulcanization speed is very low under most conditions only by using the crosslinking agent, the use value is not high, and a vulcanization accelerator and a vulcanization activator which can improve the vulcanization speed of rubber, reduce the vulcanization temperature, reduce the dosage of the crosslinking agent and improve the vulcanization degree and the activity of the accelerator are required to be added. The process conditions necessary for vulcanization, namely vulcanization temperature, time and pressure. Therefore, the reasonable determination and strict control of the vulcanization process conditions are key links for determining the quality of rubber products.
The microwave heating principle is as follows: when microwave is used for heating rubber, under the action of a rapidly changing microwave field, the polar orientation of polar molecules in the rubber changes along with the change of an external electric field, so that the effect of the spin motion of the polar molecules is caused, electromagnetic loss occurs, the field energy of the microwave field is converted into heat energy in a material, the temperature of a medium is increased, and the purpose of heating by using the microwave is achieved.
At present, heating equipment for rubber vulcanization is mostly heated by conventional hot oil, and because the rubber has low thermal conductivity, the time and energy consumption are long when the rubber is completely heated to the temperature required by vulcanization reaction; thereby also having below the equipment that vulcanizes through microwave heating rubber in the market, the conveyer belt transmission material is adopted in the microwave heating device who uses more for heating device can't seal, causes the microwave to leak, and is very big to operating personnel's bodily injury.
