Fiber Drawing Process Test

- May 11, 2017-

In the fiber drawing process test, the electric-melt non-water-cooled molybdenum electrode is used to control the electrician parameters and the glass depth of each part in the furnace reasonably. Brushed leakage board selection of high-temperature thermal creep properties of platinum Rhodium-25 alloy for the substrate material, molding zone blow forced cooling the root of the beans, making the best wire drawing viscosity, glass liquid crystal, in order to ensure the stability of the wire drawing operation and high-strength monofilament.

By the fiber drawing process test concluded: First, the use of 5% modified oxide cerium (CEO2) replaces 5% SiO2, making the glass liquid process performance greatly improved, the glass liquid viscosity correspondingly has a larger decline, the crystallization temperature of glass liquid drops to about 1300 ℃, which is advantageous to drawing work; second, the temperature distribution of glass liquid in the furnace is uniform, the temperature gradient is smaller, the surface temperature of glass liquid is higher, which is conducive to the rapid melting of cold glass, and the highest temperature in the furnace is lowered. To reduce the corrosion and corrosion of refractory materials to the glass pollution; Thirdly, the viscosity of high-strength glass is slightly larger, so the cooling position is low, the cooling strength is small, the silk root molding is longer, the molding performance is better, is suitable for continuous pulling glass fiber; In addition, high-strength glass wire wiredrawing when the phenomenon of flying silk is relatively small, the wire drawing work more stable, single machine production is higher; fourthly, the mechanical properties of high strength glass fibers are good, their single filament strength, original yarn rupture strength and elastic modulus are better.
