Abstract

The invention relates to a basalt fiber acupuncture filtering felt, in particular to a basalt fiber acupuncture filtering felt and a making process thereof. The invention aims at providing a basalt fiber acupuncture filtering felt with high temperature resistance, static prevention and higher breaking strength and a making process thereof. The invention has the technical scheme that the basalt fiber acupuncture filtering felt is made by base cloth and basalt fiber layers on the upper layer and the lower layer of the base cloth in an acupuncture process, wherein the base cloth is made from basalt fiber yarn as a raw material, and the basalt fiber layers are made in a mechanical net-formation process. The making process of the basalt fiber acupuncture filtering felt comprises the following steps of: making the basalt fiber layers in the mechanical net-formation process; making the base cloth; lapping and stacking the basalt fiber layers on the upper surface and the lower surface of the base cloth, and making a semi-finished product of the basalt fiber acupuncture filtering felt by acupuncture; dipping in emulsions, and then making the basalt fiber acupuncture filtering felt by usinga tentering and sizing furnace. The basalt fiber acupuncture filtering felt provided in the invention has the advantages of high mechanism strength, high temperature resistance, static prevention andwide application.

Description

technical field [0001] The invention relates to a needle-punched filter felt, in particular to a basalt fiber needle-punched filter felt and a manufacturing process thereof. Background technique [0002] Basalt fiber is drawn from volcanic basalt at a high temperature of 1500 degrees Celsius. It has chemical stability, physical stability, anti-ultraviolet radiation, wave-absorbing function, wave-transmitting function, non-toxicity, no molten droplets when burning, and burning smoke. Low density, environmental protection and no pollution. At the same time, basalt fiber has extremely high service temperature, high fracture degree, high modulus, excellent mechanical, physical and chemical functions, extremely low thermal conductivity, high sound absorption coefficient, extremely low moisture absorption, and high specific volume Resistance, anti-ultraviolet, wave-absorbing function, anti-radiation, anti-electromagnetic, combustion without molten droplets, low combustion smoke d...
