棕剛玉
棕剛玉以優質鋁礬土為原料，無煙煤，鐵霄，在電弧中經2000度以上高溫熔煉制成，經自磨機粉碎整形，磁選去鐵，篩分成多種粒度，其質地致密、硬度高，粒形成球狀，適用於制造陶 瓷、樹脂高固結磨具以及研磨、拋光、噴砂、精密鑄造等，還可用於制造高級耐火材料。
棕剛玉具有純度高，結晶好，流動性強，線膨脹系數低，耐腐蝕的特點。經數十傢耐火生產企業實踐驗證，該產品在應用過程中具有不起爆、不粉化、不開裂的特點。尤其是其遠高於傳統棕剛玉的性價比，更使之成為棕剛玉質耐火材料的最佳骨料和填充料。
產品粒度按國際標準以及各國標準生產，可按用戶要求粒度進行加工。通用粒度號為 F4~F320，其化學成份視粒度大小而不同。突出的特點是晶體尺寸小耐沖擊，因用自磨機 加工破碎，顆粒多為球狀顆粒，銳石牌棕剛玉具有純度高，質地致密，堆積密度大，自銳性強，韌性好，磁性物含量特低的特點，用其制成的磨具磨削鋒利，發熱率低，磨削比高，且使用時沾附少；制成的燒結磨具具有燒成後顏色深藍、不起網狀裂紋、無銹斑的特點，適用於制造陶瓷、樹脂高固結磨具以及研磨、拋光等。
棕剛玉磨料的用途
棕剛玉砂又名石榴子石系屬矽酸鹽類礦物，經過精心篩選，機械加工，篩選分級等方法制成的研磨材料，主要用於研磨玻璃制品制品，工業除銹及水切割等。（1）對矽片、光學鏡頭 、精密機器機表、拋光玻殼、玻璃器皿、陶瓷石料、皮革、 塑料、金屬機件能提高光潔度。（2）可噴砂切割，是制造砂輪、油石、砂佈、砂的必須原料。（3）可作為修築高速公路路麵、飛機跑道、耐磨橡膠、工業地坪.防滑油漆等尚佳的耐磨材料。（4）可作化工、石油、制藥、水處理過濾的介質和鉆井泥漿加重劑。（5）對電鍍、核污染的防護具有良好的效果。 (6) 是水洗廠牛仔服噴砂車間用砂.水切割行業優質的配砂。

Brown aluminium oxide
With bauxite, carbon material, iron filings as raw materials, Brown Fused Alumina is restored and obtained through the melting of the brown the brownartificial corundumin the furnace above 2200℃, and made of a variety of particle sizes products by purifying, crystallization, sorting, crushing, magnetic separation and screening methods. With its dense texture, high hardness and the formation of spherical particles, it is suitable for the manufacture of ceramics and resin, as well as the high-Bonded Abrasives grinding, polishing, sand blasting, precision casting and so on, also can be used to manufacture high-grade refractory material.
Brown Fused Alumina has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant and other characteristics. Dozens of refractory manufacturers have proved in practice that the product has not detonate, non-powder, non-cracking characteristics in the application process.
Particle size is in accordance with international standards and can be processed as requirements. Universal size: No. F4 ~ F320, its chemical composition varies depending on grain size. Its prominent feature is the small crystal size, impact resistance and spherical particles. This product has high purity, dense texture, large bulk density, strong self-sharpening, good toughness, low level magnetic material content and other characteristics
