Background technique
Due to the fast development of modern information technologies, small size, high sensitivity and quickly are had increasing need in electronic field
The sensor and coil of response, and this be unable to do without high-precision, high performance insulating wrapped metal composite wire, traditional enameled wire by
It is difficult to meet the needs of high performance coil in heat resistance and insulating properties.In recent years, glass fluxing technique gold is prepared by melt spinning method
The problem of belonging to silk, then preferably resolving the thermal stability and small size of composite filament.But glass bag is prepared using melt spinning method
It covers metal fibril and needs electromagnetic field suspended metal molten bath, therefore the quality of metal bath is small (for several grams of quantitative levels), causes to melt
The stability contorting difficulty for melting spinning technique is high, and composite filament and metal core filaments dimensions are difficult to stablize, and is difficult to prepare larger straight
The glass fluxing technique wire of diameter (diameter is the 0.1mm order of magnitude).It is compound using the biggish glass fluxing technique of core filaments diameter fluctuation range
Silk prepares high performance electronic product, then can reduce the sensitivity and precision of its product.
