As a commonly used basalt material in the road and building materials industry,many people may not be very familiar with it.Its performance has been widely used,and its fibers can also play a key role in medicine.Many people may not be very familiar with it.Let's briefly introduce it together below:
The acidity coefficient Mk of basalt stone fiber is(WSiO2+WAl 2 O3/(WCaO+WMgO),and the lower the Mk,the better its chemical durability.In this case,the temperature requirements are also relatively high.The formula for calculating the pH value of CBF is pH=-0.060 2WSiO2-0.12 WAl 2 O3+0.232WCaO+0.120 WMgO+0.144WFe 2O 3+0.217WNa2O，pH The higher the value,the more alkaline oxides there are,and the poorer the water resistance.Generally,under normal circumstances,<4 is stable,<5 is stable,and<6 is moderately stable.

The fiber calculation method is 5.48, with a pH value of 1.7. Its operating temperature range is -269~650 ℃, while glass fiber is 60~450 ℃. At a high temperature of 900 ℃, the mass loss of CBF is 12%, so CBF is used as a high-temperature filtration material for air purification and disinfection in the process of antibiotic production.
In fact, as a new type of material, basalt stone fiber has a considerable use in our daily lives. If you want to learn more about basalt stone products in the future, you can continue to follow us.
