First, the appearance quality
The first way to judge whether basalt fiber is good or bad is to look at its appearance quality. Good basalt fibers should have a smooth appearance and be free of defects such as burrs, cracks, and pitting. When selecting, you can observe the texture of the fiber surface, and the smooth feel is generally of better quality.
2. Weight
Secondly, the weight of basalt fiber is also an important basis for judging the quality of the fiber. Good basalt fiber is relatively light in weight and less dense, suggesting that it is lighter in weight and less prone to breakage.
3. High temperature resistance
The quality of basalt fiber can also be judged by its high temperature resistance. Good basalt fiber should have high temperature resistance, and there should be flame self-extinguishing after combustion, and there should be no odor, smoke, oil dripping and other phenomena, which is an important condition to ensure that it is not affected by high temperature.
Fourth, other key features
In addition to the above three methods, the quality of basalt fibers can also be judged from other key characteristics. For example, good basalt fiber shows the characteristics of water resistance, anti-corrosion, strong acid resistance, and alkali resistance; Pollution of the environment should also be strictly controlled.
