Insulating method of thermocouple leg body conductors
专利汇可以提供Insulating method of thermocouple leg body conductors专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain insulation of desired length easily, prevent short-circuiting due to contact, and facilitate discrimination of leg body polarity, by coating the positions desired to be insulated with Alundum dispersion, and giving primary heating, then giving secondary heating in reducing atmosphere.
CONSTITUTION: Using aqueous solution of aluminum nitrate as a dispersion medium, Alundum medium is caused to disperse in the positions desired to be insulated in thermocouple leg body conductors. The mixing ratio of dispersion medium and alundum powder should be proper to allow smooth coating. And coating is repeated until a desired thickness is obtained. Thus coated layer is heated primarily in the atmosphere to oxidize the aluminum nitrate into aluminum oxide. Then, in the oxidizing or reducing atmosphere, selected according to the material of the leg body conductors, the coated layer is heated secondarily at about 1000°, in order to intensify the bonding of alundum particles and the adhesion to the leg body conductors. Thus, the insulation of desired length may be esily obtained
