棕剛玉:blown fused alumina
生產工藝:又稱金剛砂,是以鋁礬土,焦炭(無煙煤)
為主要原料,在電弧爐內經高溫冶煉而成。主要成分為AL2O3,和TiO2。另外還有少量的SIO2和Fe2O3.,
性能:具有耐高溫,耐腐蝕,硬度大,強度高,耐磨損,結晶好,膨脹系數低等特點。微晶硬度:努譜硬度HV1800-2200kg/mm2,莫氏硬度9.0體積密度為3.85/cm3,,最高使用溫度1850℃,熔點2250℃
顏色:為深棕色,煅燒後為深藍色。
用途:1.噴砂棕剛玉,2.自由研磨,3.樹脂磨具,4.塗附磨具,5.磨料水力切割, 6,耐火材料。棕剛玉功能性填料——主要用於汽車制動件、特種輪胎、特種建築制品等領可作為修築高速公路路麵、飛機跑道、碼頭、停車場、工業地坪、體育場地等耐磨材料;
過濾介質——是磨料的新型應用領域,采用粒狀磨料作過濾床的底層介質,凈化飲用水或廢水,是國內外新型的水過濾材料,尤其適用於有色金屬選礦、石油鉆井泥漿加重劑
水洗棕剛玉磨料優點:
粉塵小:用水洗金剛砂進行表麵噴磨處理,由於它的比重比較高,所以在噴射過程中產生的粉塵比較少,這一點保證瞭操作員的健康和安全,提高瞭操作員的能見度,與礦渣相比較(礦渣形成過程中是用冷水甚至是海水進行高溫冷卻,所以形成的是玻璃相結構,具有易碎性),由於礦渣比較脆,在噴磨過程中,易被撞碎形成小顆粒,由於礦渣比重比較小,造成小礦渣顆粒懸浮在空氣中,造成對環境的污染,同樣,石英砂也是一種非常易碎的磨料,在噴磨過程中,會產生大量的對人體有害和對環境有嚴重污染的矽酸粉塵,這種粉塵一旦被人體吸入,很容易導致矽肺病甚至是癌癥。
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。並且本廠產品研磨時間短,效益高,但價格低廉,這些可以禰補壽命短而不足。
高效率:水洗金剛砂在一定壓力作用下,能夠大量快速地用鋒利的棱角撞擊物體表麵,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麵,從而產生一個非常高的清洗速度——通常情況下,這個速度(m2/h r)比其他常規磨料快兩倍。
