? ? ? 上海頂央棕剛玉是以鋁礬土、焦碳為主要原料,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,適用于制造陶瓷、樹脂高固結磨具以及研磨、拋光、噴砂、精密鑄造等,還可用于制造高級耐火材料。
?
? ? ? 棕剛玉俗名又稱金剛砂,具有純度高,結晶好,流動性強,線膨脹系數低,耐腐蝕的特點。該產品在應用過程中具有不起爆、不粉化、不開裂的特點,尤其是其遠高于傳統棕剛玉的性價比,更使之成為棕剛玉質耐火材料的骨料和填充料。棕剛玉粒度砂是由人工精選棕剛玉塊,采用對輥、球磨、巴馬克等設備加工而成,粒度有F8-F1500。主要用于拋光、研磨、工業磨削等。

? ? ? 粉塵小
?
? ? ? 用水洗棕剛玉進行表面噴磨處理,由于它的比重比**,所以在噴射過程中產生的粉塵比較少,這一點保證了操作員的健康和**,提高了操作員的能見度,與礦渣相比較,由于礦渣比較脆,在噴磨過程中,易被撞碎形成小顆粒,礦渣比重比較小,由此小礦渣顆粒懸浮在空氣中,造成對環境的污染。
?
? ? ? 水洗棕剛玉是水洗廠牛仔服、水切割行業優質的配砂。本廠產品自銳性好,邊角鋒利,在不斷粉碎中形成新的棱刃,介殼狀斷口硬度均勻,對所磨器具、物件不會造成劃傷現象,而且化學成分穩定,耐酸堿,具有其他磨料和人工合成磨料不可替代的優勢。
?
? ? ? **率
?
? ? ? ?水洗棕剛玉在一定壓力作用下,能夠大量快速地用鋒利的棱角撞擊物體表面,所以被視作是一種非常快的噴磨方式,在氣流中顆粒加速度和速度是慣性和顆粒大小產生的作用,越小的顆粒,加速越容易,因此能產生更高的沖擊力沖擊物體表面,從而產生一個非常高的清洗速度,通常情況下,這個速度比其他常規磨料快兩倍。
?
?
? ? ? 低碳棕剛玉經過爐前和特殊工藝的再處理,降低棕剛玉中殘余碳的含量,使產品在使用中不粉化、不爆裂、韌性大是磨料磨具行業,耐火材料行業的**原料。主要用于陶瓷磨具、**磨具、有機磨具、砂帶、涂附磨具等,根據殘碳含量分為:煅燒棕剛玉C?≤0.05%;低碳棕剛玉C?≤0.10%;普通棕剛玉C?≤0.15%;
?
?
? ? ? 1、由于有耐高溫、耐腐蝕、高強度等性能,故用澆鋼滑動水口,冶煉稀貴金屬、特種合金、陶瓷、煉鐵高爐的內襯、理化器皿、火花塞、耐熱抗氧化涂層。
? ? ? 2、由于有硬度大、耐磨性好、強度高的特點。在化工系統中,用做各種反應器皿和管道,化工泵的部件;做機械零部件、各種模具,如拔絲模、擠鉛筆芯模嘴等;做刀具、模具磨料、材料、人體關節、密封模環等。
? ? ? 3、剛玉保溫材料,如剛玉輕質磚、剛玉空心球和纖維制品,廣泛應用于各種高溫爐窯的爐墻和爐頂,既耐高溫又保溫。
