Description
Technical field
The present invention relates to a kind of pyroceram fibre, particularly pyroceram fibre of a kind of solubility and its production and application.
Background technology
The main component of traditional ceramics fiber (pure aluminium silicate series ceramic fiber) product is aluminium sesquioxide (Al
2O
3) and silicon-dioxide (SiO
2), account for 98～99% of product gross weight, wherein Al
2O
3Be about 46%, SiO
2Be about 53%, its resistant to elevated temperatures working temperature is at 1000 ℃～1260 ℃.This ceramic fiber has fine particle and part fiber to be inhaled into human body in producing preparation and use, owing to be difficult to be excreted, can produce certain harm to human body, thereby reduce work efficiency of workers.The ceramic fiber of human body fluid has appearred dissolving in foreign market at present, though this ceramic fiber is excreted easily through the reaction with body fluid, reduced harm to a certain extent, but also had at present the defective of the low and structural fragile of fibre strength human body.
The present invention just is being based on above-mentioned background, has proposed a kind of new soluble pyroceram fibre, has resistance to elevated temperatures and the structural strength that has further improved ceramic fiber on the basis of solubility, has significantly enlarged the range of application of ceramic fiber.
Summary of the invention
The object of the present invention is to provide a kind of new ceramics fiber, not only can be dissolved in human body fluid, reduce harm, improve the security of producing and using, and have better resistance to elevated temperatures and structural strength human body.
The present invention is achieved by the following technical solutions:
A kind of soluble pyroceram fibre is provided, is prepared from by following raw materials by weight percent:
Silicon-dioxide 60～70%, aluminium sesquioxide 5～15%, calcium oxide 6～10%, magnesium oxide 6～10% and zirconium white 3～6%.
Described soluble pyroceram fibre preferably is prepared from by following raw materials by weight percent:

The present invention also provides a kind of preparation method of described soluble pyroceram fibre, may further comprise the steps:
Described raw materials by weight percent is got rid of silk with tumbling machine after 2200 ℃ high-temperature fusion, make described soluble pyroceram fibre, described tumbling machine is three centrifugal tumbling machines or the centrifugal tumbling machine of diaxon.
The present invention also provides a kind of application of described soluble pyroceram fibre, and promptly described soluble pyroceram fibre is used for 1000 ℃～1200 ℃ industrial production environment high temperature resistant, heat insulation or fire-retardant.
Above-mentioned application is that described soluble pyroceram fibre is further made the heat insulation or fire-retardant of the industrial production environment that is used for 1000 ℃～1200 ℃ behind tapetum fibrosum, fibrefelt, fiberboard, fibre module, fibrous paper or the fiber textile according to ordinary method.
The present invention has significantly improved the solubleness of ceramic fiber by add the calcium oxide and the magnesium oxide of described dosage in raw material, has improved to become fine environment, has stablized the chemical ingredients of soluble ceramic fiber.Simultaneously, by in raw material, having added the zr element of described dosage, in the solubility that has guaranteed ceramic fiber, make the structural strength of ceramic fiber obtain remarkable reinforcement.
Soluble pyroceram fibre of the present invention dissolves in human body fluid after being inhaled into human body, can be decomposed and excrete after producing reaction with human body fluid, thereby significantly reduced harm to human body.
The diameter of the soluble pyroceram fibre by prepared of the present invention is at 3～4 μ m, and staple length is greater than 100mm, and the slag ball is greater than 0.23mm, and slag ball content is less than 5%.
Compared with prior art, beneficial effect of the present invention is:
1. fibrous texture intensity height
With under the isodensity, tensile strength and other existing soluble fiber that the present invention contains the zirconium soluble fiber have tangible difference.As density is 64kg/m
3The time, existing other soluble ceramic fiber tensile strength are up to 38/Kpa, and the present invention to contain zirconium soluble fiber tensile strength be 40/Kpa.When density is 96kg/m
3The time, existing other soluble ceramic fiber tensile strength are up to 68/Kpa, and the present invention to contain zirconium soluble fiber tensile strength be 80/Kpa.
2. the product use range is wide
Characteristics such as high structural strength that ceramic fiber of the present invention had and environmental protection make its prepared product can use in fields such as iron and steel, industrial furnace, aluminium metallurgy, casting, chemical industry, boats and ships, space flight, sealing, automobile, electric prospection, buildings.And in a single day the soluble ceramic fiber that does not possess the high like this structural strength of ceramic fiber of the present invention runs into wet environment in engineering construction, fiber has very big loss, thereby reduce the performance of product fire resistant heat preserving, its use range also just is narrower than soluble ceramic fiber of the present invention relatively.
3. chemical composition stability
Soluble ceramic fiber of the present invention has improved chemical stability after adding zirconium.The non-zirconium soluble ceramic fiber heat shrink rate that contains is 6% at 1300 ℃, is 8% at 1400 ℃; Is 3% and the present invention contains zirconium soluble ceramic fiber heat shrink rate at 1300 ℃, is 4% at 1400 ℃.
4. staple length is long, and slag ball rate is low
The staple length of ceramic fiber of the present invention is greater than 100mm, and slag ball content is less than 5%; The staple length of existing other soluble ceramic fibers is at 50-80mm, and slag ball content is at 8-10%
