耐高溫耐低溫研磨砂白剛玉220#

 

噴砂用白剛玉砂選用充分冶煉結(jié)晶的白剛玉固定爐料，經(jīng)過破碎、篩分等工藝生產(chǎn)而來。噴砂用白剛玉的粒徑范圍經(jīng)過嚴(yán)格控制，使磨粒大小控制在一定范圍內(nèi)。噴砂后產(chǎn)生表面一致的粗糙度。白剛玉韌性好，研磨能力強(qiáng)，自銳性好，噴射到噴砂工件表面時(shí)，通過氣流的沖擊力，工件撞擊出凹痕。鈍化后的噴砂表面有利于后續(xù)噴漆的油漆保持把持力。白剛玉噴砂磨粒還具有噴砂效率高，利用率高的優(yōu)點(diǎn)。

 The white fused aluminum oxide used for sandblasting is produced by using fully melted and crystallized white corundum as fixed furnace material, and is processed through processes such as crushing and screening. The particle size range of white corundum used for sandblasting is strictly coolled to keep the abrasive particle size within a certain range. After sandblasting, a consistent surface roughness is produced. White corundum has good toughness, strong grinding ability, and good self sharpening. When sprayed onto the surface of sandblasted workpieces, the impact force of the airflow causes the workpieces to produce dents. The sandblasted surface after passivation is beneficial for maintaining the grip of subsequent paint spraying. White corundum sandblasting abrasive particles also have the advantages of high sandblasting efficiency and high utilization rate.

白剛玉的特性：

1.    白剛玉顯微硬度20.58Gpa,維氏硬度2200-2400kg/mm2，莫氏硬度9.0�？蓢娚坝诖蟛糠纸饘�、鑄鋼件、鑄鐵件、有色金屬合金材料、含鉻含錳含鎢鉬金屬、玻璃和其他非金屬材料。

2.    白剛玉研磨能力強(qiáng)，噴砂效率高，由于具有很強(qiáng)的自銳性 ，不會(huì)對(duì)噴砂表面造成燒*氧化。

3.    白鋼玉還可以直接用于研磨拋光，表面處理，噴砂除銹等領(lǐng)域，可用于干式和濕式噴砂，表面拋毛拋光，噴涂前表面處理鈍化等領(lǐng)域。

4.    白鋼玉氧化鋁的純度高，主要晶相時(shí)α相的氧化鋁。雜質(zhì)少，磁性物含量低，噴砂后不會(huì)產(chǎn)生化學(xué)殘留，可用于醫(yī)藥、航空、食品領(lǐng)域機(jī)械部件的噴砂。

 

 Feature：

1. The microhardness of white corundum is 20.58Gpa, the Vickers hardness is 2200-2400kg/mm2, and the Mohs hardness is 9.0. It can be sandblasted on most metals, steel castings, cast iron, non-ferrous alloy materials, chromium, manganese, tungsten and molybdenum metals, glass, and other non-metallic materials.

 

2. White corundum has strong grinding ability and high sandblasting efficiency. Due to its strong self sharpening property, it will not cause burning and oxidation on the sandblasted surface.

3. White steel jade can also be directly used in fields such as grinding and polishing, surface treatment, sandblasting and rust removal. It can be used in dry and wet sandblasting, surface roughening and polishing, and surface treatment passivation before spraying.

 

4. The purity of white steel jade alumina is high, and the main crystal phase is α Phase alumina. With low impurities and low magnetic content, sandblasting does not produce chemical residues and can be used for sandblasting mechanical components in the fields of medicine, aviation, and food.
