Centrifugal glass wool seems to be widely used in construction. Is it harmful to the human body? What is the difference between the centrifugal glass wool and common glass wool? The Centrifugal glass wool is a kind of common glass. Glass wool can be divided into superfine wool and centrifugal glass wool.
Manufacturing techniques of them are different.
They are basically the same.
Ultra-fine glass wool is of thin fiber, high softness and less dust, but high price while the centrifugal glass wool is of coarse cotton yarn, poor compression rebound but the price is relatively cheap.
Fine glass fiber cotton is an excellent inorganic non-metallic materials and it has a wide range of varieties. The advantages of it are good insulation, heat resistance, corrosion resistance, high mechanical strength, but the drawback is brittleness and wear resistance.It is made of glass ball or abandoned glass and goes though process of high temperature melting, drawing, winding and weaving. The diameter of the monofilaments is from several microns to twenty microns, equivalent to 1 / 20-1 / 5 of a human hair and each bundle of fiber strands is composed of hundreds or even thousands of monofilament.Glass fibers are commonly used as reinforcing materials, electrical insulating materials, insulation materials and circuit boards in the field of composite materials.Centrifugal glass wool is a silk material which is made by blowing the molten glass by centrifugal blowing processes and spraying thermoset resin. After thermal curing and deep processing, the silk material can be into products with a variety of usages.Centrifugal glass wool is a typical porous sound-absorbing material with fluffy fiber staggering inside and a lot of tiny pores existing.
