Abstract
The invention discloses a preparation method of a glass phase in electrical resistance slurry, wherein the preparation method comprises the particular preparation steps: (1) placing silica, bismuth trioxide, zinc oxide, zirconium oxide and boron oxide in a three-dimensional swinging mixer, and mixing; (2) loading the mixture into a crucible, placing the crucible in an electric melting furnace, melting, then immediately taking out to put into water, and carrying out water quenching; (3) carrying out preliminary crushing of the mixture with an impact crusher, then placing the obtained powder into a pulverizer, carrying out secondary pulverization, then placing the obtained powder into a gas-blowing flotation machine, removing impurities, then placing into a ball mill, adding water, and carrying out ball milling; and (4) placing the mixture fine powder into a drier, drying, annealing after drying, then naturally cooling, to obtain a glass powder, adding the glass powder into the electrical resistance slurry, and mixing to obtain the glass phase. The preparation method has the beneficial effects that the glass powder particle size is finer and more uniform, and through the multi-step process, noise interference caused by the glass powder particles is greatly reduced.
Description
Technical field
The present invention relates to resistance slurry preparing technical field, the preparation method of glass phase in particularly a kind of resistance slurry.
Background technology
Thick-film resistor is to rely on interparticle contact in glass basis to form resistance, and its cost is relatively low, and frequency response speed is fast,
It is used widely in non-precision appliance applications.Contact in thick-film resistor constitutes complete resistance, but the thermal strain meeting in work
Interrupt contact.Due to parallel connection in most cases, thick-film resistor will not be opened a way, but resistance can increase with constant temperature over time
Plus.
The charge movement of bunchiness in actual electrical equipment is due to structure, granular texture also can make thick-film resistor produce very high making an uproar
Sound, has influence on the electrical application performance of reality.
