7.磨料水力切割——是以磨料作切割介质,依靠高压水力射流进行基本切割,应用于石油(天然气)管道、钢材等部件的切割,是一种新型、环保、安全的切割方式。
8.产品可靠,性能稳定,品质优良,使用方便。
水洗棕刚玉磨料优点:
粉尘小:用水洗金刚砂进行表面喷磨处理,由于它的比重比较高,所以在喷射过程中产生的粉尘比较少,这一点保证了操作员的健康和安全,提高了操作员的能见度,与矿渣相比较(矿渣形成过程中是用冷水甚至是海水进行高温冷却,所以形成的是玻璃相结构,具有易碎性),由于矿渣比较脆,在喷磨过程中,易被撞碎形成小颗粒,由于矿渣比重比较小,造成小矿渣颗粒悬浮在空气中,造成对环境的污染,同样,石英砂也是一种非常易碎的磨料,在喷磨过程中,会产生大量的对人体有害和对环境有严重污染的硅酸粉尘,这种粉尘一旦被人体吸入,很容易导致硅肺病甚至是癌症。
【开元棕刚玉】产品自锐性好,边角锋利;在不断粉碎中形成新的棱刃,介壳状断口硬度均匀,对所磨器具、物件不会造成划伤现象,而且化学成分稳定,耐酸碱,具有其他磨料和人工合成磨料不可替代的优势。并且本厂产品研磨时间短,效益高,但价格低廉,这些可以祢补寿命短而不足。
高效率:水洗金刚砂在一定压力作用下,能够大量快速地用锋利的棱角撞击物体表面,所以被视作是一种非常快的喷磨方式,在气流中颗粒加速度和速度是惯性和颗粒大小产生的作用,越小的颗粒,加速越容易,因此能产生更高的冲击力冲击物体表面,从而产生一个非常高的清洗速度——通常情况下,这个速度(m2/h r)比其他常规磨料快两倍。

The scope of application of brown fused alumina
Brown fused alumina called industrial teeth: mainly used in refractory materials, grinding wheel, sand.
1. The sand brown corundum - sand abrasive hardness modest, bulk density is high, no free silica, more than major, good toughness, Mr Kay brown fused alumina is the ideal "environmental protection" type sand materials, widely used in aluminum, copper material glass, washing jeans precision mould, etc;
2. Free abrasive, abrasive abrasive, level used in tube, optical glass, monocrystalline silicon, glasses, watches and clocks, glass, crystal glass, jade and other areas of free grinding, is the widely adopted advanced grinding materials;
3. Resin abrasive, abrasive has the right color, hardness and toughness, suitable particle section type and cutting edge keep degrees, used in resin grinding tool, the effect is ideal;
4. Coat with abrasive, abrasive is abrasive paper, cotton and other production manufacturer production raw material;
5. Brown corundum functional filler, mainly used in automobile brake parts, special tires, special building products brought can be used as building highway pavement, runway, docks, car parks, industrial floor, sports venues and wear resistant materials;
6. The filter medium - is abrasive new application fields, the granular filter bed for the bottom of the abrasive medium, purify drinking water or wastewater at home and abroad, is a new type of water filtration material, especially suitable for non-ferrous metal processing, oil drilling mud weighting agent:
7. Abrasive hydraulic cutting - is abrasive for cutting medium, rely on high pressure water jet in basic cutting, used in the oil (gas) pipe, steel etc cutting, it is a kind of new type, environmental protection, safe way to cut.
Customer: washing factory cowboy sand workshop shipyard shipyard steel structure plant powder for our factory ShaBuChang sand, crystal glass industry building floor industry steel hardware industry electronics qi car manufacturing coast terminals, parking lot hospital stadium. Sand industry cooperation content to all types of users required floor aggregate and abrasive.
8. Products and reliable, stable performance, good quality, easy to use.
Washed brown fused alumina abrasive advantages:
Little dust: wash emery surface spray grinding processing, because of its specific gravity is higher, so in the injection process of dust is less, which ensure the operator\'s health and safety, to improve the operator\'s visibility, and slag phase comparison (slag formation process is to use cold water and even the sea for high temperature cooling, so is the formation of glass phase structure, has the fragility), because of the slag is brittle, in spray grinding process, easy to be crash form small particles, due to the relatively small proportion of slag, cause small slag particles suspended in the air, causing the environmental pollution, also, quartz sand is also a very fragile abrasive jet mill, in the process, can produce a large amount of harmful to human body and the environment have serious pollution of the silica dust, the dust once inhaled by human beings, it is easy to lead to silicosis and even cancer.
Is the washing factory jeans. Water cutting industry quality with sand. Our products since the sharpness, edge sharp; In the constant grinding in forming a new edge blade, conchoidal fracture hardness even, the grinding apparatus, object won\'t cause scratches phenomenon and chemical stability, acid and alkali resistant, with other abrasive and synthetic abrasive irreplaceable advantages. And the products of our factory grinding time is short, high efficiency, but the price is low, these can you fill life short and shortage.
High efficiency: washing emery in certain pressure, can under the action of a large number of fast with sharp Angle impact surface, so be regarded as is a very quick spray grinding way, in the gas particle
