Basalt filter bag is an industrial dust filter bag made of basalt fiber.Basalt is a natural volcanic rock.It is made into basalt fiber by melting and drawing.This fiber has many excellent properties and is used in filter bag manufacturing to form basalt filter bags.Its main features and advantages include:

●Technical Parameters

●High temperature resistance
Basalt fiber has excellent high temperature resistance and can usually be used in high temperature environments of about 600℃,which is suitable for filtering high temperature flue gas.
●Corrosion resistance
Basalt material has good acid and alkali corrosion resistance and is suitable for filtering some corrosive gases.
High mechanical strength
Basalt fiber has high tensile strength and wear resistance,making the filter bag more durable and longer life.
●Environmentally friendly and natural
Basalt is a natural mineral material with an environmentally friendly production process and no harmful substances released.
●Good filtration efficiency
Basalt filter bags can effectively filter industrial dust and ensure that emissions meet standards.
●Application fields
Basalt filter bags are suitable for industries such as steel,electricity,cement,metallurgy,and chemicals,and are especially suitable for dust removal of ultra-high temperature and highly corrosive gases.
In short,basalt filter bags are high-temperature,corrosion-resistant,environmentally friendly,and stable industrial dust removal filter bags,suitable for dust control under harsh working conditions.
