    莫來石簡介

     

          莫來石(或莫乃石)是一系列由鋁硅酸鹽組成的礦物統稱,這一類礦物比較稀少。是鋁硅酸鹽在高溫下生成的礦物,人工加熱鋁硅酸鹽時會形成莫來石。天然的莫來石晶體為細長的針狀且呈放射簇狀。莫來石礦被用來生產高溫耐火材料。莫來石是一種優質的耐火原料,這一類礦物比較稀少。

     

          明悅莫來石主要特點為:膨脹均勻,熱震穩定性極好,荷重軟化點高,高溫蠕變值小,硬度大,抗化學腐蝕性好。目前,我公司現貨供應天然燒結莫來石,高含量電熔莫來石。

     

    Mullite (or MoNaiShi) is a series of aluminium silicate mineral collectively, this kind of mineral is scarce. Is aluminum silicate under high temperature generated minerals, artificial heating will form mullite aluminum silicate. Natural mullite crystals as elongated needle and radiation clumps. Mullite ore is used to produce high temperature refractory materials. Mullite is a kind of excellent refractory raw material, this kind of mineral is scarce.

    Mullite main characteristic is: the uniform expansion, excellent thermal shock resistance, high load softening point, high temperature creep value is small, high hardness, good resistance to chemical corrosion. At present, our company cash supply natural sintered mullite, fused mullite high content.

     

    【莫來石分類】

     

          明悅莫來石合成生產工藝有燒結法和電熔法兩種。燒結莫來石產品質量好,即結晶細小,相互犬牙交錯,組織結構致密均勻;電熔莫來石產品礦相分布欠佳,易有氣泡,其組織結構致密牢固。我國用全天然料燒結莫來石按Al2O3含量分為M70、M60、M45三個牌號,每個牌號有三個品級。

     

          燒結莫來石采用優質天然原料,經多道工序精選均化,高溫煅燒制成。燒結莫來石產品質量穩定,廣泛用于生產各種抗熱震性優良的高溫低蠕制品。

     

          電熔莫來石采用高純度石英砂、工業氧化鋁,在超大電弧爐上熔煉而成,莫來石色澤白、殘碳極低、氣孔率低、雜質含量低、抗折強度大,荷重軟化溫度高,硬度大,高溫蠕變小、針狀晶體發育良好,莫來石以其優秀的抗熱震性能及耐磨性能,被廣泛應用于玻璃窯體爐襯磚、莫來石磚,大型冶煉高爐熱風爐磚、高爐低蠕變硅線石磚,陶瓷窯具、匣缽、棚板、石油化工等行業,莫來石是高檔耐火材料的原材料。常用規格:0-1、1-3、3-5、5-8、8-15mm及200目、325目等。

     

    Mullite composite production process with sintering, and fused method two kinds. Sintered mullite products of good quality, that is, crystal small, jagged, dense homogeneous structure; Fused mullite products poor ore phase distribution, easy to have bubble, its organizational structure dense solid. China's press with all natural materials sintered mullite Al2O3 content into M70, M60, M45 three grades, each brand has three grades.

    Sintered mullite is made of high quality natural ingredients, after selection process more homogenization, high temperature calcination. Sintered mullite products stable quality, widely used in the production of various kinds of good thermal shock resistance of high temperature and low creep products.

    Fused mullite using high purity quartz sand, alumina industry, on the large electric arc furnace smelting, mullite colour and lustre is white, low carbon residue, low porosity, low content of impurities, flexural strength, high refractoriness under load, high hardness, high temperature creep, acicular crystals have well developed, mullite, with its excellent thermal shock resistance and abrasion resistance, are widely used in glass kiln body lining bricks, mullite bricks, large blast furnace hot blast stove brick and low creep blast furnace sillimanite brick, ceramic kiln furniture, sagger, shed board, petrochemical and other industries, mullite is high-grade refractory raw materials.

    Specification: 0 and 1, 3, 3-1-5, 5-8, 8-15 mm and 200 mesh, 325 mesh.
