Abstract
The present invention belongs to a refractory heat-insulating material, which relates to an environment protection type ceramic fiber needling blanket and a manufacturing method thereof. Ceramic fibers are manufactured by that raw materials are melted and formed into fibers; the ceramic fiber needling blanket is manufactured by collecting cotton, needling, hot treating and cutting. The main raw materials of the ceramic fibers are Silicon dioxides and Aluminum oxides; the present invention is characterized in that the present invention comprises the following components of the following proportion by weight: four to six shares of Magnesium oxides and / or Calcium oxides. The fibers are formed by adopting the process of spraying and blowing, or fling fibers in a centrifugal way. The present invention has the advantages long and soft fibers, large strength, favorable refractory properties, low fusion temperature of the raw materials, easy fiber forming, large temperature ranges, high yield of the fibers and stable quality; dust which is deflected to acidness reacts with body fluids after the dust enters human bodies, and most of the dust is decomposed and exhausted, so the harm is lightened; the present invention has the gloss of the fibers, and nonfiber objects are less than 8%; when textiles are manufactured, fibers which are cut are few, the rate of finished products is high and the strength is large in the process of acting of stress, such as the force of cutting, stretching, bending, etc.
Description
Technical field
The invention belongs to refractory thermal insulating material, is a kind of inorfil (for example, alumina-silicate ceramic fibre) blanket of resistance to elevated temperatures, is specifically related to a kind of environment protection type ceramic fibre needle punched blanket and preparation method thereof.The present invention is to use the temperature can be at 900～1100 ℃, and textile performance excellent high-temperature textile fabric is suitable for the raw material as equipment, pipeline heat-insulating fiber textile simultaneously.
Background technology
Traditional ceramics fiber (alumina-silicate ceramic fibre) product, its main component is Al
2O
3And SiO
2, both account for 97%, and all the other 3% are potassium, sodium, iron etc., and melt temperature is greater than 2000 ℃; Get rid of silk or blowing method production owing to adopt, fiber finer (3～5 μ m) in addition, thus cause a large amount of dust and particle in process of production.Contain 30～60% SiO in these dust
2, its chemical property meta-alkalescence (pH7～8), enter human body by respiratory system after owing to can not be decomposed by human body and all discharge.In the course of time, when these dust after human body inner product coalescence acquires a certain degree, just can produce harm to health, produce such as occupational diseases such as anthraco-silicosises.
Summary of the invention
The object of the invention provides a kind of fiber of slant acidity own, after the dust of slant acidity enters human body in the production, with the human body fluid effect, is decomposed, discharges, thereby alleviate harm to human body.
Technical scheme of the present invention is: develop a kind of environment protection type ceramic fibre needle punched blanket, raw material is made ceramic fibre through fusion, one-tenth fibre, through collecting cotton, acupuncture, heat treatment and cutting, make the ceramic fibre needle punched blanket again; The main raw material of its ceramic fibre is silica and alundum (Al, and feature is also to contain weight in the component of its ceramic fibre to form 4～6 parts magnesia or calcium oxide.
Contain weight in the component of its ceramic fibre and form 55～75 parts silica; Contain weight in the component of its ceramic fibre and form 20～40 parts alundum (Al; Allow to contain other impurity of 0.5～1%.
A kind of preparation method of environment protection type ceramic fibre needle punched blanket is characterized in that fine employing of one-tenth of its ceramic fibre jetted or a centrifugal technology of getting rid of.The melt temperature of its raw material is 1700～1900 ℃; The fine temperature of the one-tenth of its raw material is 1550～1700 ℃.
The ceramic fibre that the listed proportioning of the present invention produces has the following advantages:
1. its chemical property slant acidity (pH6.1～6.5), after the dust of these slant acidity entered human body, with humoral effect, major part was decomposed, discharges, and has alleviated the harm to human body;
2. ceramic fibre has silky gloss, and fiber length (80～300mm), fiber softening, intensity is big, and non-fiber (slag ball) is less than 8% (former technology 10%);
3. in order to the producd fibers textiles, sheared, stretched, in the carding step of crooked iso-stress effect, the cut-out of fiber is few, thereby guarantees to obtain yield rate height, wool top that intensity is big, yarn; And has good heat resistance (900～1100 ℃);
4. after adding magnesia or calcium oxide, the raw materials melt temperature is low, and melt is fit to become fine temperature range big (1550～1700 ℃), becomes easily fine, fiber recovery rate height, and fiber quality is stable.
The specific embodiment
Embodiment 1 raw material weight proportioning: silica: alundum (Al: magnesia=55: 40: 4; Through 1700～1900 ℃ of fusions, in 1550～1700 ℃, winding-up or a centrifugal technology of getting rid of become fibre to make ceramic fibre with raw material, the fibre property slant acidity, and its pH6.1～6.5, non-fiber (slag ball) is less than 8%; Through collecting cotton, acupuncture becomes blanket again, and the blanket base after the acupuncture becomes blanket through 700～900 ℃ high-temperature shaping, and cutting obtains the ceramic fibre needle punched blanket of quality softness.Because raw material is easy to get, and its melt temperature is lower, so product cost is lower, can help being applicable of product.
The present invention and conventional ceramic fibre comparative result: * solubilized degree-refer to body fluid solubilized degree
