Description
Technical field
The present invention relates to high-tension power transmission and transformation equipment technology, and in particular to a kind of insulated porcelain sleeve inorganic adhesive and its gluing
Technique.
Background technology
At present, insulated porcelain sleeve is widely used in high voltage power transmission field, and the quality of insulated porcelain sleeve for power transmission network to extremely closing
It is important, wherein, the mucilage binding quality of metal cap on insulated porcelain sleeve body and metal pedestal is fixed in insulation porcelain by bonding mode
Critical role is occupied in the Performance Evaluation of set.
In general, metal cap and the mucilage binding of metal pedestal are bonded by insulation compound, during bonding, first by sizing material
Bonding site for the treatment of coated in insulated porcelain sleeve blank, is then sleeved on corresponding site by metal cap or metal pedestal, after insert plus
In hot equipment, solidification is realized by the method integrally heated to porcelain piece.But traditional insulation compound is as organic insulation
Sizing material, bonding efficiency is low, and high energy consumption, cementing strength is inadequate, and degumming phenomenon easily occurs in use, and if thickening the easy shadow of glue-line
Processing and transaction capabilities are rung, and insulating properties is also poor.In addition, the defects of mobility is larger when bonding also be present in organic sizing material,
The flowing of sizing material easily makes the ad-hoc location starved of bonding plane and causes bonding interface electric durability when bonding agent is heated in solidification process
Decline, on the other hand easily because the defects of sagging adhesive vestige is also easy to produce on porcelain piece surface to the part, it is necessary to carry out volume
Outer removing glue processing, causes cost increase and percent defective increase.
