The batch materials enter the kiln to be melted, and enter the platinum-rhodium bushing through the heat preservation of the passage, and the platinum-rhodium bushing needs to be electrified and heated to enable the glass to flow out through a bushing nozzle of the bushing.
The platinum and rhodium powder and the platinum-rhodium alloy bushing plate can be subjected to erosion of high temperature, oxidizing atmosphere and molten glass liquid at the drawing operation temperature (1100-1500 ℃) of glass fibers or basalt fibers at high temperature, and the interaction of the dead weight of the glass liquid and the tensile stress of glass fibers in the bushing plate and the bushing plate cavity. In addition, platinum-rhodium alloys are subject to changes in the texture crystal structure of the alloy under high temperature conditions. Under the combined action of the factors, some metals exposed in the air are gradually oxidized and volatilized, part of the oxidized and volatilized metals are deposited on the surface of the alloy, part of the oxidized and volatilized metals are deposited inside pouring refractory materials of the bushing, part of the oxidized and volatilized metals are evaporated and dispersed into the air, and the rest of the oxidized and volatilized metals are remained in glass fibers along with molten glass, so that the platinum and rhodium of the bushing is seriously lost.
