Described immediate heating type electrothermal tube is characterized in that described infiltration layer processed by nanoscale tin particulate, and conductive layer is processed by nano-sized crystal attitude tin, and protective layer is processed by the oxide of aluminium.
Described immediate heating type electrothermal tube is characterized in that described infiltration layer processed by stannous chloride, and conductive layer is processed by nanoscale tin micro mist, and protective layer is processed by the nanometer aluminum micro mist.
The multilayer composite metal film electrothermal tube structure that the utility model adopts can make the metalfilmresistor stability of processing improve greatly, and resistance value changes hardly in time, and therefore, also greatly prolong its useful life, skin; The oxide alundum (Al of aluminium has been blocked the infiltration of oxygen toward conductive layer, and the metal particle in the protection conductive layer is not oxidized, thereby has guaranteed the stable of resistance value.
With the performance of existing electrothermal tube; The electrical power density of the utility model electrothermal tube has improved 50%, and the single tube electric rating improves 65%, and electrical strength improves 1.5 times; Insulation resistance has improved 4 times; Improve 4.5 times useful life, power attenuation reduces more than 10%, and leakage current closely is original 15%.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-quartz ampoule; 2-infiltrates layer; The 3-conductive layer; The 4-protective layer; The 5-silver electrode.
Embodiment
Below in conjunction with Figure of description the utility model is further specified:
The immediate heating type electrothermal tube is provided with infiltration layer 2 quartz ampoule 1 surperficial the spraying, infiltrates layer 2 surperficial a spraying conductive layer 3 is set, and the conductive layer 3 surface sprayings that conductive layer 3 two ends are equipped with between 5, two silver electrodes 5 of silver electrode are provided with protective layer 4.
Defectives such as the utility model is according to original metal film electrothermal tube operation principle, and is not high to film resistance stability, and useful life is not long are innovated on the resistive element structure, adopt multilayer composite metal film resistance structure.This structure is divided into three layers with metalfilmresistor, and nexine is for infiltrating the nanoscale tin particulate basic unit of quartz ampoule, to improve the adhesion strength and the conductive capability of resistive film and quartz ampoule; The middle level is a nano-sized crystal attitude tin crystals layer, is the conductive bodies layer of resistive element; Outer then be the protective oxide film of aluminium, play the protective resistance body.The resistance two ends are silver coating, work the electrode effect that connects, and peg graft with base, and the base inwall is copper structure, constitute conductive path with silver electrode.Such composition metal resistive film greatly improves its stability, so its bulk life time is improved because outer field protection has been arranged.The prescription of nexine is principal phase with the stannous chloride, and the middle level is a principal phase with nanoscale tin micro mist, skin then with the nanometer aluminum micro mist as principal phase.
The multilayer composite metal film electrothermal tube structure that the utility model adopts can make the metalfilmresistor stability of processing improve greatly, and resistance value changes hardly in time, and therefore, also greatly prolong its useful life, skin; The oxide alundum (Al of aluminium has been blocked the infiltration of oxygen toward conductive layer, and the metal particle in the protection conductive layer is not oxidized, thereby has guaranteed the stable of resistance value.
With the performance of existing electrothermal tube like following table; The electrical power density of the utility model electrothermal tube has improved 50%, and the single tube electric rating improves 65%, and electrical strength improves 1.5 times; Insulation resistance has improved 4 times; Improve 4.5 times useful life, power attenuation reduces more than 10%, and leakage current closely is original 15%.
