Problems solved by technology

[0003] The advantage of ceramic fiber is high temperature and good performance at high temperature, but its biggest defect is that it is non-degradable and harmful to the human body. Most of these refractory fibers have a diameter of less than 6 μm. In addition, they are brittle and easy to break to produce fiber dust. Inhaled into the human body, thereby affecting human health, inducing inflammation of the respiratory system and even cancer
and cause some harm to the environment

specific Embodiment approach

[0023] The specific implementation method is as follows, wollastonite is CaSiO 3 or CaOSiO 2 , containing SiO 2 51.75%, CaO48.25%. Often contain iron, manganese, magnesium;

[0024] Quartz sand: ordinary quartz sand, namely SiO 2 ≥90-99%Fe 2 o 3 ≤0.06-0.02%, the refractoriness is 1750℃.

[0025] Theoretical composition of zircon sand (zircon) (wB%): ZrO 2 67.1%, SiO 2 32.9%.

[0026] The chemical composition of talc is Mg 3 [Si 4 o 10 ](OH) 2 .

Embodiment 1

[0028] With 10% talc, 50% quartz sand, 38.5% wollastonite, 1% zircon sand and 0.5% P 2 o 5 As the raw material, mix it evenly, put the evenly mixed raw material in a resistance furnace, and melt it at 1500-2000°C; the molten liquid is passed through the spinning method, and the cotton is collected by the cotton collector to obtain a fiber cotton blank with a required thickness, and then passed through the needle The thorns are heat treated at 600-850°C, and finally cut and rolled to form the invention.

Embodiment 2

[0030] Use 5% talc, 45% quartz sand, 47.5% wollastonite, 2% zircon sand and 0.5% P2O5 as raw materials, mix evenly, put the evenly mixed raw materials in a resistance furnace, and heat through 1500~ Melting at 2000°C; the molten liquid is passed through spinning, and the cotton is collected by the cotton collector to obtain a fiber cotton blank of required thickness, then undergoes acupuncture, heat treatment at 600-850°C, and finally cuts and rolls to form the invention.

Abstract

The invention discloses a 1,100-DEG C ecological soluble environment-friendly refractory fibre, which comprises the following materials by mass percent: 55-75 percent of SiO2, 10-30 percent of CaO, 0-10 percent of MgO, 1-2 percent of ZrO2, 0.1-0.5 percent of P2O5, and less than 5 percent of other impurities. The refractory fibre provided by the invention can replace aluminum silicate refractory fibre, is soluble in human body fluid, and can also be decomposed and emitted, to reduce the damage for human body and to improve the production and use safety. Besides, the refractory fibre has sufficiently high high-temperature resistance and structural strength, and has a long-time working temperature reaching1,100 DEG C.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a 1100-degree ecologically soluble and environmentally friendly refractory fiber. Background technique [0002] In 1941, the Central Research Institute of Babcock & Wilcox Co. in the United States discovered that a stream of kaolin melt was sprayed with compressed air to obtain a fiber similar in shape to asbestos. China began to trial-produce ceramic refractory fibers from the early 1970s. Generally, raw materials such as coke, kaolin, quartz sand, and alumina are used to produce fibers through electric arc or resistance furnace melting. The main components are Al2O3 and SiO2, and they are successfully used in industry. Furnace, and has been widely used in various industrial fields such as metallurgy, machinery, petroleum, chemical industry, electronics and light industry. In addition, it has also been applied in cutting-edge science and technology such as aerospac...
