Description

technical field [0001] The invention relates to the technical field of basalt production, in particular to a hollow basalt fiber production device and a production method. Background technique [0002] Basalt continuous fiber is a pure natural inorganic non-metallic material, and it is one of the most important components in the new material industry. Traditional solid basalt fibers generally have a higher density, usually 2.6-2.7g / cm 3 about. It is generally used as a structural force in the fiber-reinforced composite material industry, resulting in a higher density of the composite material. At the same time, the sound insulation and heat insulation properties of solid fibers are weak, and it is difficult to give full play to the characteristics of the integration of structure and function of fibers at the same time. Traditional solid basalt fibers are greatly restricted in the application fields that need to meet both structural and functional requirements. [0003] Th...

It is generally used as a structural force in the fiber-reinforced composite material industry, resulting in a higher density of the composite material

At the same time, the sound insulation and heat insulation properties of solid fibers are weak, and it is difficult to give full play to the characteristics of the integration of structure and function of fibers at the same time. Traditional solid basalt fibers are greatly restricted in the application fields that need to meet both structural and functional requirements.

[0003] The inventors of the present application found in the process of realizing the technical solution that the current molding equipment for basalt fibers is aimed at traditional solid fibers, and there is no molding equipment related to the manufacture of hollow basalt fibers
