The surface of the slag wool is smooth and cylindrical, and its cross-section is a complete circle. This is mainly due to the fact that the blast furnace slag shrinks into a circular shape with the smallest surface area under the action of surface tension before cooling and solidifying into fibers.
When the acidity coefficient is 1.0-1.3, the fibers of blast furnace slag are thin and the fibers are arranged in an orderly manner; with the increase of the acidity coefficient, the fiber diameter tends to increase, and at the same time, a small amount of slag balls are included in the fibers, and the fiber quality deteriorates. Generally speaking, the higher the acidity coefficient, the better the chemical durability of slag wool. However, when the acidity coefficient is too high, the resulting fibers may be longer. Although the chemical stability is improved, it is more difficult to melt, the fibers are thicker, and even cannot be formed into fibers. Therefore, in actual production, the acidity coefficient of slag wool can generally only be maintained at 1.2, and it is difficult to reach 1.3.
● Non asbestos
Our slag wool mineral fiber has no asbestos and can be ideal alternatives of asbestos for friction application. What’s the most important, it is at far lower price than asbestos.
● Low Ignition loss
At high temperature, some inorganic substances in mineral fibers will be burned off, resulting in fiber loss on ignition rate. Slag wool mineral fiber are pure inorganic fiber without any organic composition, so it hardly have a fiber burn rate.
● Very low shot content
The HB11X shot content can be controlled below 2% after six times of shot removal process. Shot will bring wear and noise. Shot content is one of the standards to velue fiber quality.
● Excellent stability
Excellent stability, temperature resistant, corrosion resistant, moisture resistant and wear resistant.A
