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。

是水洗厂牛仔服.水切割行业优质的配砂。本厂产品自锐性好,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 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。

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 use of the brown fused alumina,

Brown fused alumina teeth called industry: mainly used in refractory materials, grinding wheel, sand blasting.

1. Sand corundum, sandblasting abrasive hardness is moderate, high packing density, no free silica, than major, good toughness, Mr Kay brown fused alumina is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, water wash jeans precision molds, and other fields; Level 2. Free grinding, grinding abrasive, applied to the tube, optical glass, silicon single crystal with glass, mirror, clock and watch, crystal, jade and so on in the field of free abrasive, grinding is adopted widely in the domestic advanced materials; 3. Resin abrasive, abrasive has color appropriate, good hardness and toughness, suitable particle cross section type and keeping degree blade, used in resin abrasive effect is ideal; 4) is coated with abrasive, abrasive abrasive paper, gauze production factory production of raw materials; 5. Brown fused alumina filler - is mainly used for automobile brake parts, special tires, special construction products such as led can be used as building highway pavement, airport runway, wharf, parking lot, industrial floor, wear-resisting material such as sports venues; 6. The filter medium, is a new kind of application field, abrasive using granular grinding as filter medium, the bottom of the bed, purify drinking water or wastewater is a new type of water filtration materials at home and abroad, especially in non-ferrous metal ore dressing, oil drilling mud weighting agent:

7. Hydraulic cutting - an abrasive abrasive cutting medium, rely on high pressure water jet cutting, basic application in the oil (gas) pipelines, steel parts such as cutting, is a new type, environmental protection, safe way of cutting.

Customer base: washed denim sandblasting factory workshop repairing yard shipyard steel structure factory powder factory our sandpaper, ShaBuChang crystal glass industry building floor steel hardware industry electronics industry qi car manufacturing coast terminals, parking lot, hospital, stadium. Sand industry and other cooperation required floor aggregate content to all types of users and abrasive. 8. The product is reliable, stable performance, good quality, easy to use.

Washed corundum abrasive advantages:

Little dust: wash emery grinding surface spray processing, because of its specific gravity is higher, so less in the injection process of dust, it ensures the operator's health and safety, and improve the operator's visibility, comparing with the slag, slag formation in the process of high temperature is even in cold water is seawater for cooling, so the phase structure is formed by glass, have fragility), because slag is brittle, in the process of jet mill, easy to be smashed to form small particles, due to the relatively small proportion of slag, cause little slag particles suspended in the air, causing pollution to the environment, also, quartz sand is a kind of very friable abrasive, in the process of jet mill, will produce large amounts of harmful to human body and there are serious pollution to the environment of silicate dust, once the dust is inhaled, it is easy to cause silicosis disease and even cancer.

Are jeans washing plant. Water cutting industry quality with sand. Our products are good self-sharpening, sharp edges; Form new blade edges in the shattered, conchoidal fracture surface hardness is uniform, to the grinding tools, objects will not cause scratch phenomenon, and chemical stability, resistance to acid and alkali, and other abrasive and artificial abrasive irreplaceable advantages. And our products are milling time is short, high efficiency, but the price is low, these can fill your life short and insufficient.

Efficiency: water emery under certain pressure, to a large number of rapidly with a sharp impact surface edges and corners, it could be seen as a very fast way of jet mill, particle acceleration and velocity in air is inertia and the role of particle size, the smaller the particles, accelerate the easier, thus can produce higher impact shock surface, to produce a very high speed of cleaning - typically, this speed (m2 / h r) two times faster than other conventional abrasive.

Packaging and shipping instructions:

gongyi city every abrasives factorybag of 25 KGS net each white woven bag packing. Stored during transport to prevent damaged packaging, in order to avoid loss or mixed with sundry. Unfavorable transportation stacked together with supporting and other filter material.
