Study on Rheological Properties of Silica Sol in Sisal Fibber Reinforced Investment Casting

Abstract:

In casting temperature Laquan silica sol crust process suitable for the production of surface roughness is small, precision high accuracy in size, and has become the mainstream technology has been widely used. Silicon sol casting with high dimensional accuracy, good surface quality and other advantages, is a widely used less advanced technology without cutting, using silica sol casting method can save a lot of machine equipment and processing time, but also greatly saves metal materials. Hard fiber sisal has high tensile strength, resistance to seawater immersion, friction resistance, flexibility and other characteristics, can be used for fishing, sailing, mining, transportation rope, canvas, waterproof cloth and other raw materials. The most commonly used binder in investment casting is silica gel solution (abbreviated as silica sol), such as ethyl silicate hydrolysate, water glass and silica sol.
