1-3mm地坪防腐材料黑刚玉 万丰黑刚玉段砂现货

【黑刚玉简介】
       黑刚玉是将铝矾土于电弧炉中经2000度以上高温熔炼制成，经自磨机粉碎、整形、磁选去铁等多道工序，筛分成多种粒度。隆泰黑刚玉成品是一种以a-AL2O3和铁尖晶石为主矿相的灰黑色结晶体，具有韧性高、耐高温、热太性能稳定的特点。磨料组成基本粒集中，切削力强，耐磨性好，工效高。主要用于金属制品、光学玻璃、竹木制品的抛光和喷砂，又是制造树脂砂轮、切割片、砂布的新颖磨料。
【黑刚玉特点】
       黑刚玉产品规格有：16#-400#的各种粒度。粒度均匀，硬度高，亲水性强，光洁度好，自锐性强。适用于树脂切割片，喷砂抛光，制磨纸浆砂轮，电子工业的半导体荧光屏，光学工业的镜头镜片的研磨；对印刷板，皮革骨料，塑料玉石的加工；尤其对电镀前底面，电镀层，不锈钢，铜，铝制品的抛光具有良好的效果。
